QUANTUM™ CONTROLLER BOARD IDENTIFICATION

INTRODUCTION

Frick® Controls has over the years, strived to remain onthe cutting edge of microprocessor technology anddevelopment. In addition, because of the ever-increasingspeed, memory, features, and power of microprocessors,Frick® Controls will continue to introduce the latestadvancement in microprocessor control technology.

Our microprocessor family has shared the nameQuantum™ over the past six years. There are currentlyfour controllers within this family. The first two of thesecontrollers (known as Quantum™ 1 and Quantum™ 2) areno longer in production, and as such, will not be furthermentioned in this manual. The two current members inproduction of the Quantum™ family are the Quantum™ 3,and the Quantum™ 4. It is critical to the end user to beable to identify the differences between these controllers.Refer to the section in this manual entitled “Quantum™ 3Main Board History and Identification” and “Quantum™ 4Main Board History and Identification” for additionalinformation as to how to identify the particular Quantum™controller that you have.

Throughout this manual, the two different controllers willbe talked about for the most part as one (as they dofunction the same). Please note however that there is aseparate section for both the Quantum™ 3 and for theQuantum™ 4, where all of the individual specifics areidentified and explained. This is why it is important for youto be aware of which version of Quantum™ board youhave.

Quantum™ 4

TROUBLESHOOTINGTHE QUANTUM™ CONTROL PANEL

This section contains information on troubleshooting andmaking corrections to the boards and control circuits of theQuantum™. Reference the drawings at the end of thismanual.

GENERAL INFORMATION:

The components within the control panel can beinadvertently damaged by static electricity ormishandling. Only qualified technicians shoulddirectly handle these components.

1. DO NOT attempt to make corrections to thepower supply without shutting off the power to thecontrol panel. Accidental shorts can irreparablydamage the processor boards or the displayscreen.

2. DO NOT HANDLE the panel boards when theircables are disconnected without first attaching aproperly grounded wrist ground strap to preventstatic electrical discharge from your body.

Most problems encountered with the microprocessor andcontrol circuits will be the result of a wiring fault, a blownfuse, faulty I/O module or failure of a peripheral controlsuch as a solenoid coil or a temperature sensor. Faults inthe computer, while possible, are unlikely. If a faultdevelops in the computer, the probability is that allfunctions will cease and the display screen will go blank.The control system consists of an AC (high voltage) side,which can be either 120 volts, or 230 volts, and a DC (lowvoltage) side. The AC side actuates solenoids, relays,alarms, and other electromechanical functions. The DCside operates the computer and it's various sensors.

When working within the panel, the AC high voltageside, which can be either nominal 120 VAC or nominal230 VAC, CAN CAUSE INJURY OR DEATH.

To troubleshoot the low-voltage side of the control circuits,it is necessary to have the following tools:

1. Accurate digital multimeter (capable of reading tothe hundreds of a volt)

2. Small wire stripper

3. Small screwdriver (with insulated shaft)4. Small snip nose pliers

5. Wrist Grounding strap6. Static free grounded work surface

Note: Proper panel voltage refers to the AC (high volt-age) that has been supplied to the panel, which couldbe either nominal 120 VAC or nominal 230 VAC(Reference the Control Panel Power Specifications).

Some problems that are encountered involvetroubleshooting the panels digital inputs and outputs. TheGCU Board has 1 digital input connector (J10), and twodigital output connectors (J7 & J9). Additionally, there arethree analog input connectors (J4, J5 & J11) and 1 analogoutput connector (J8).


ACUair SYSTEM DESCRIPTION

The heart of the ACUair control system is the Quantum™controller. This is where all setpoints for system operationare entered and all data is viewed from. The Quantum™controller can have up to four GCU (General Control Unit)controllers connected to it. Each GCU controls a single airhandling unit and provides the actual control of digital andanalog inputs and outputs for the unit that it is mounted to.Each GCU controller runs a software program that isindependent of the Quantum™ controller. The Quantum™program communicates to the GCU to monitor data, andeven if the Quantum™ controller were to be powereddown, each of the potentially available four GCU’s willcontinue to function normally, as they do not rely on theQuantum™ for control (only data acquisition).

Additionally, the Quantum™ can be communicated with bya various array of protocols and software packages, suchas HMI (Human Machine Interface). These packages areusually custom designed by the end user and loaded ontoa desktop PC, and allow the PC to provide various dataacquisition and control functions remotely. For the enduser that does not wish to design their own package, aturn-key (out of the box) package is available from Frick®

Controls. The name of the software is Q-Talk, a turn-keypackage that has been specially designed to mimic thegraphic screens that are present on the Quantum™controller. Data may be viewed and changed, as well asprovide remote system control. Contact Frick® for moreinformation on this product.

WHAT TO DO BEFORE CALLING THE FACTORY

When someone calls in to the factory with a suspectedQuantum™ problem, sometimes the person calling doesn'tprovide enough information. This is because they mostlikely are not aware of the type of information that wouldbe useful to factory personnel in helping to identify andcorrect the problem. An example of this is the statementthat the Quantum™ is not “booting” (the main processorboard is not starting). Unfortunately, this description isusually vague and only means that there is nothing on thedisplay. A blank screen could be the result of manydifferent problems. Following is a list of possible reasonsfor no display:

• No power

• Loose or Faulty Display Cable or Inverter Cable

• Bad Display

• Bad Backlight Inverter

• Bad Backlight Fluorescent Tube

• Wrong Combination of Display, Cable, Inverter,or Software

• Faulty CPU Board

Before calling the factory for assistance, review theinformation on the following pages and try to discover andresolve your Quantum™ problem. The actual cause ofmost problems is usually not with the Quantum™ itself,but with something external to the Quantum™. However,on the rare occasion that the problem has been identifiedas being the Quantum™ controller, use the followingsection as a guideline for replacing it.

REPLACING THE QUANTUM™ BOARD

The Flash Card memory load is done prior to the boardshipping. The customer should still have their settingsmanually recorded, and saved to a Flash Card, so that thenew board can be setup the same as the old one. It issuggested that the operator first record all controlsetpoints prior to board replacement. Factory Setupsettings will also be lost. The setpoint data sheets areuseful for recording this information. A MaintenanceFlashcard may also be purchased that will allow thesesetpoints to be saved electronically, and may bedownloaded later. Make sure that the operator can accessFactory Setup to restore all compressor specific settings.

The procedure to replace the main board is outlinedbelow:

1. Shut off control power.2. Remove the old board from the machine and the

new board from its packing and place both on ananti-static surface.

3. Ensure that the jumpers on the new board are setthe same as those on the old board.

4. Install the modified replacement board into thepanel.

5. If program changes are necessary through aFlash Card download, then follow the directionsin the Factory Setup manual (S90-500 FSI) forthe procedure to reload a program Flash Card.


QUANTUM™ 3 CONTROLLER

WHAT SHOULD OCCUR WHEN POWERING UPTHE PANEL

The first thing that should be checked whentroubleshooting the Quantum™ is it’s powering upsequence.

When powering up the Quantum™, the followingsequence of events is indicative of a properly workingmain processor board:

• The LED’s for +5V, +12V, and –12V will turn onsolid. (Lower left corner of Main PCB)

• LED KB will begin to blink. (Left side of MainPCB)

• Several initialization screens will appear (thesewill look very similar to the way the screen of adesktop computer appears when it is booting.

• The last of the initialization screens is the“System Configuration” screen.

• Various POST codes will appear.

• The screen will go then show Looking forboards…

• The “Air Handling Unit Overview” screen isshown.

After the Quantum™ has properly powered up, thefollowing sequence of events is indicative of propercommunication to the connected GCU boards:

• The TX/RX LED’s near the white connector willbegin to blink.

• All connected GCU boards' TX/RX lights shouldbe blinking.

• Each GCU board should have the power LED’s(+5 and +12) lighted and the “Status” LED shouldbe blinking.

WHAT IF THE “AIR HANDLING UNIT OVERVIEW”SCREEN IS NOT SHOWN

If the “Air Handling Unit Overview” screen is not shown,check the following items:

1. If no LED’s are lighted, then check AC and DCpower.

2. Check if the lighting of the LED’s is occurring asdescribed in the “What Should Occur WhenPowering Up The Panel” section.

• If the powering up sequence continues torepeat without displaying the “Air HandlingUnit Overview” screen, then there is a“booting” problem.

3. Check if an error message is displayed whenbooting.

• Be sure to write down any error messagesexactly as they appear.

4. Check that the software is OK:• Is the correct software installed?• Did you just install new software?

• Is the program that the Quantum™ isrunning the same that all GCU boards arerunning?

• If you need to clear the numerical setpointand calibration areas of memory for anyreason, clear the memory as described inthe S90-500 FSI publication. NOTE: Thisinformation will be replaced by factorydefault values, so any setpoint andcalibration data values that need to becustomized must be reentered.

5. Check for bad or loose connections.

6. Check the display. If the CPU board is bootingbut you have no display, check the following:

• Check the LCD backlight tube. Look veryclosely at the display to see if anything isvisible in the dark screen. Using a beam typesource of good lighting, such as a flashlight,look for any “ghost” type image. If it appearsthat there is something on the screen butvery dark, the problem maybe the LCDbacklight tube. On the LG Philips, NEC, andSharp displays this tube is field replaceable.On the Samsung LCD display, it is notavailable and the display will have to bereplaced. There may be a sticker on thedisplay mounting plate. If there is, it will havea part number that describes the type ofdisplay. If there is no sticker, you must takethe display apart to identify the displaymanufacturer.

• Verify that both the display cable and theinverter cable are firmly seated. It may benecessary to remove the video cable fromthe back of the LCD display and reseat it tobe sure it is connected properly. Note: Thisis a small connector and caution shouldbe observed so that it is not damageddue to excessive force.

• Check the backlight inverter connector (P4).When the Quantum™ board is mounted inthe panel, this connector is located at themiddle left of the board. The pins on the rightside are odd numbered, with pin P(1) at thebottom -pin P(9) at the top. The pins on theleft side are even numbered, with pin P(2) atthe bottom - pin P(10) at the top. After theQuantum™ has booted, pin P(3) shouldmeasure +2.4 Vdc, pins P(4) and P(5) areDC grounds, and pins P(6) and P(7) shouldmeasure +12 Vdc. A bad inverter will alsocause a dark display.

• Reference the “Display AssemblyComponent Replacement Guide” in the“Identifying the Type of Display” section thatappears later in this manual, and check thatthe LCD, LCD cable, and software versionsare matched correctly.

QUANTUM™ 4 CONTROLLER

WHAT SHOULD OCCUR WHEN POWERING UPTHE PANEL

The first thing that should be checked whentroubleshooting the Quantum™ is it’s powering upsequence.

When powering up the Quantum™, the followingsequence of events is indicative of a properly workingmain processor board:

• Green PWR (Power) LED will turn on solid (upperright corner of main PCB).

• Red FLASH LED will begin to intermittentlyduring the Boot process. It will then go out oncethe “Air Handling Unit Overview” screen appears.

• LED D8 (on the smaller board) will start to blinkat the rate of about once per second. It willcontinue to blink after the Quantum™ hasbooted.

• Several initialization screens will appear (thesewill look very similar to the way the screen of adesktop computer appears when it is booting.

• The last of the initialization screens is the“System Configuration” screen.

• Various POST codes will appear.

• The screen will go then show “Reading DataFrom File"

• “Looking For Boards”, will be seen next

• After the screen displays "Looking For Boards",LED's D4, D5, D7 and D8 will be on solid.

• The “Air Handling Unit Overview” screen willappear.

• Once actual data has been displayed on thisscreen, LED D13 will come on solid and D10,D11, and D12 will start to flash at a quick rate.

After the Quantum™ has properly powered up, thefollowing sequence of events is indicative of propercommunication to the analog and digital boards:

• The TX/RX LED’s near the white connector willbegin to blink.

• All connected GCU boards' TX/RX lights shouldbe blinking.

• Each GCU board should have the power LED’s(+5 and +12) lighted and the “Status” LED shouldbe blinking.

WHAT IF THE “Air Handling Unit Overview”SCREEN IS NOT SHOWN

If the “Air Handling Unit Overview” screen is not shown,check the following items:

1. If no LED’s are lighted, then check power AC andDC.

2. Check if the lighting of the LED’s is occurring asdescribed in the “What Should Occur WhenPowering Up The Panel” section.

• If the powering up sequence continues torepeat without displaying the “Air HandlingUnit Overview” screen, then there is abooting problem.

3. Check if an error message is displayed whenbooting.

• Be sure to write down any error messagesexactly as they appear.

4. Check that the software is OK:

• Is the correct software installed?

• Did you just install new software?

GCU (GENERAL CONTROL UNIT) BOARDS

The information that follows in this section can help locateproblems that can occur with GCU Input and Output circuitboards, and their interaction with the Quantum™controller.

GCU Board Description

The GCU Board is actually a small microprocessor boardand programmed to control discrete outputs, or acceptingdiscrete inputs, from external electrical devices. EachBoard has the capability of 16 output channels and 8 Inputchannels. Additionally, there is the capability for 11 Analoginput channels and 4 Analog output channels. With theQuantum™ ACUair® Control, these I/O channels arededicated as to their function, through the operatingsystem (software), enabled options and external wiring.Each channel that is used by the software will have amodule plugged into it. A yellow module indicates that it isused for Inputs. A black module is used for Outputs. Thestandard Quantum™ ACUair® package can have from oneto four GCU Boards in the control network.

Communications LED's

The Quantum™ controller is in constant communicationwith all GCU Boards. You will notice on each GCU board,that there are a pair of LED's that are labeled as RX1 andTX1. These letters represent Receive (RX) and Transmit(TX). These LED's should be flashing at a fairly high rateduring normal operation. This indicates that theQuantum™, and the GCU Board that you are looking at,are properly communicating with each other.

• Reference the “JUMPER AND DIPSWITCHSETTINGS" section later in this manual. Thissection contains the dipswitch settings foraddressing the GCU Boards numbers (1) through(4). When these switches are properly set, theQuantum™ is able to serially communicate witheach GCU board and provide data exchange. Ifthese switches are not properly set, the result willbe lost or failed communications.

Connections to the Quantum™

As stated earlier, the Quantum™ standard ACUair®

control system utilizes up to four GCU Boards (in separateenclosures). To connect all of these boards together sothat the Quantum™ can interface with them, they must beinterconnected with a two-wire cable that provides thecommunications capabilities. These two signals are theRX (receive) and TX (transmit). These signals are themeans by which the Quantum™ communicates to theGCU.

Logic Voltage (Power) LEDs

Located on the GCU Board is a +5 and a +12 “Power”LED. These LEDs should be illuminated as long as the“Control Power” switch is ON, and the proper voltages arepresent at the GCU power connector (J1). The powersupply generates the +5 and +12 Vdc voltages, andpasses it on through a Power harness. If a voltage relatedproblem is suspected, the only way to actually determinethis is to read the voltages on a Digital Voltage Meter(DVM). This may be accomplished by locating theconnector labeled as J1 on the GCU.

To check the +5 Vdc:

Take the red (positive) probe of the DVM andcarefully insert the end into the "+5V" lead, and theblack (negative) probe end into the "GND" (Return orCommon) lead, as shown below:

Set the DVM to read "DC", and set the proper range.The voltage reading should read approximately +5.00Vdc. If the reading is below +4.90 Vdc, the lowvoltage problem will need to be corrected for properoperation of the system.

To check the +12 Vdc:

Take the red (positive) probe of the DVM andcarefully insert the end into the "+12V" lead, and theblack (negative) probe end into the "GND" (Return orCommon) lead, as shown below:

Set the DVM to read "DC", and set the proper range.The voltage reading should read approximately+12.00 Vdc. If the reading is below +11.70 Vdc, thelow voltage problem will need to be corrected forproper operation of the system.

The cause for a low voltage reading could be:

• Poor Connections. Check the power wiring forproper connectivity (loose screw connection,loose connector, broken wire, etc.).

• A problem may exist with the power supply.

• A problem may exist with GCU board.

Status LED

The GCU Board has a “Status” LED indicator on the boardthat blinks when the board’s software is running.

If the “Status” LED is not blinking, check to ensure that theEPROM is installed properly. The EPROM is located inchip slot U22.

Digital Inputs

A Digital input is the portion of the hardware that allowsdevices such as limit switches, relay contacts, and levelswitches, to interface with the GCU. The software programwithin the GCU is constantly “looking” at these Inputchannels, and based upon whether a control voltage ispresent or not, will provide the necessary control for anassociated Output channel.

+5 GND

+12 GND


Input modules are yellow in color. A side profile of thismodule is shown below:

Digital Outputs

A Digital Output is the portion of the hardware that theGCU is to control (energize). These devices includesolenoids, relay coils, fans, blower contactors and heatersto be energized, based upon the logic within the GCUsoftware program.

Output modules are black in color. A side profile of thismodule is shown below:

Although this Output module is labeled as 280 VAC on thetop, and on the side, it can be used on 120 applications.

Never plug an Input module into a position designated foran Output module.

You will notice that when a module is plugged into theGCU Board, there is a fuse located directly adjacent to themodule. This fuse is of the plugable variety, and may beremove for testing.

Checking the Digital Inputs and Outputs

Some problems that may be encountered involvetroubleshooting the digital inputs and outputs. The DigitalGCU has three Digital I/O (DIO) board connectors labeledJ7, J9 and J10. All digital I/O are wired to theseconnectors.

J10 (Input) - Positions 1, 3, 5, 7, 9, 11, 13, and 15 areNeutral connections. Positions 2, 4, 6, 8, 10, 12, 14,and 16 are 120 Vac signal inputs:

J9 (Output) - Positions 1, 3, 5, 7, 9, 11, 13, and 15are 120 Vac Hot connections. Positions 2, 4, 6, 8, 10,12, 14, and 16 are 120 Vac signal inputs:

J7 (Output) - Positions 1, 3, 5, 7, 9, 11, 13, and 15are 120 Vac Hot connections. Positions 2, 4, 6, 8, 10,12, 14, and 16 are 120 Vac signal inputs:

An LED is associated with each module and displays thestate of each module. A lighted LED represents an Inputthat is “High”, receiving a signal or an Output that is “On”.

If a properly configured GCU board is not respondingcorrectly, first look at the GCU board on the “ServiceScreen”. It is possible that one or more modules (input oroutput) has a problem:

For an Output - If the screen says that an output ison, there should be 120 volts at the terminal strip forthe corresponding output (refer to the wiringdiagrams). If it is not on, check the LED on the GCUBoard for the suspect output module. It should be lit. Ifthe LED is not lit, then check the fuse for the output(inputs do not have fuses). If the output fuse is OK,then check the module.

For an Input - If you know for a fact that a particularinput should be energized, but the screen shows it asbeing off, then verify at the field wiring terminal stripthe presence of 120 volts (refer to the wiringdiagrams). If voltage is present at the terminal strip,then measure voltage at the GCU board inputterminal strip (J10). Refer to the diagram on this pagethat shows the J10 terminal strip to identify whichposition is used for each input. If there is voltage tothe GCU terminal (J10), then replace thecorresponding input module.

Fuse Testing and Replacement

1. Power off the panel.

2. Open the panel door.

3. Remove the questionable fuse.

4. Check the fuse using a DVM.

5. If the fuse is faulty, check for external shorts onthe corresponding circuit, then replace the fusewith a new plug-type fuse (refer toRecommended Spare Parts list).

Input and Output Module Testing andReplacement

1. Power off the panel.

2. Open the panel door.

3. Replace the questionable module.

4. Power on the panel.

5. If it is an Input module, check if the associatedLED is on when power is applied to the module.

Troubleshooting an Output

1. Make sure the LED associated with the Output ison when power is applied to the module.

2. If the LED is not on when it should be and thereis no operating condition preventing it, contactthe Frick® Service Department.

3. If the LED is on when it should be, check forproper panel voltage on the DIO connector plug.Check the voltage between neutral, and theassociated signal position of the Output module.

4. If the voltage is OK, check for proper panelvoltage between the associated signal position ofthe Output module on the DIO connector and theassociated position on the terminal strip.

5. If the voltage is OK, check the wiring external tothe panel.

6. If voltage is not OK, check the fuse.

7. If the fuse is OK, then check the module.

8. If the module is OK, check for proper panelvoltage on the DIO connector plug between theoutput signal position, and neutral.

Troubleshooting an Input

1. Make sure the LED associated with the Input ison when power is applied to the module.

2. If the LED is on then the Input module is good.

3. If the LED is on and there is no input voltage,replace the Input module.

Replacing a Defective GCU Board

The procedure to replace a GCU board is outlined below:

1. Shut off control power.

2. Remove the old board from the machine and thenew board from its packing and place both on ananti-static surface.

3. Remove any required chip(s) from the defectiveboard and install them in the replacement board.Align the notch at the end of the EPROM with thenotch in the socket.

• Ensure that the GCU EPROM (installed intoU22) has the proper label affixed to it. TheVersion number should match between allGCU EPROMS, as well as the programversion of the Quantum (as shown on the“About…”screen). As an example, if theQuantum version is 2.1, then all GCU boardsmust have version 2.1. The GCU boardsmay have an additional digit in the versionnumber, such as 2.11. This final digit is notcritical with the compatibility of the system.

4. Ensure that all jumpers, dip switches, I/Omodules and components are properly setup onthe new board as it was on the old board.

5. Install the modified replacement board in thepanel.

After replacing a GCU board, it will automatically bedetected after the Quantum power has been cycled offthen on. It will then be necessary to re-enter all setpointsand calibration data to the board. Refer to the FactorySetup Instructions for more information (S90-500 FSI).

ANALOG BOARD

The optional Analog board would be installed in a GCUcontrol enclosure only when the installed options call for it.

The information that follows in this section can help locateproblems that can occur with Analog Input and Outputcircuit board, and their interaction with the GCU Board.

Analog Board Description

The Analog Board is actually a small microprocessorboard and is programmed to control analog outputs, oraccepting inputs, from external electrical devices. EachAnalog Board has the capability of 16 independentchannels or I/O (Input/Output). With the GCU ACUair®

Control, these I/O channels are dedicated, through thesoftware and external wring, as to the function of eachchannel. Each channel that is used by the software willhave to be configured for the type of device that isconnected to it (4-20 mA, 0-5 v, 1-5 v, or ICTD). Thestandard GCU ACUair® control can have up to one Analogboard (depending on options).

• Reference the “JUMPER AND DIPSWITCHSETTINGS” section later in this section. Thissection contains the dipswitch settings foraddressing the Analog I/O Board. When theseswitches are properly set, the GCU board is ableto serially communicate with the Analog I/Oboard and provide control signals and dataexchange. If these switches are not properly set,the result will be one of the following:

• The wrong analog input signals beingreceived

• The wrong analog output signals being sentfrom the board.

Connections to the Quantum™

As stated earlier, the GCU ACUair® control system utilizesone Analog Board. To connect this board so that the GCUcan provide control, it must be interconnected with a wiringharness that provides all of the necessary D.C. voltagerequirements, as well as the communications capabilities.A diagram of this wiring harness can be found later in thismanual (see the ACUair® GCU Control Panel FlowDiagram - D.C. Voltage / Communications Wiring). Thisharness has a 16-pin connector at one end, which plugsinto the Analog board. The other end has no connector,and simply wires directly into the DC power terminalsmounted on the right hand side of the GCU enclosure, andComm Port 2 (J3) of the GCU board.

Analog Inputs

An Analog Input is the portion of the hardware that allowsdevices such as temperature sensors and pressuretransducers, ammonia detectors, etc., to interface with theGCU. The software program within the GCU is constantly“looking” at these Input channels (throughcommunications) and based upon what the voltage orcurrent level of the channel is, will provide the necessarycontrol for an associated action.

Analog inputs arrive at the board on connectors P1through P8. Each of these connectors can receive twochannels (for a total of sixteen).Each of the sixteen analog input channels is boardconfigurable to select for the following input signals:

• 4-20 mA

• 0-5 volt

• 1-5 volt

• ICTD

Refer to the Analog Board drawing and Analog BoardSettings pages that appear later in this section for specificinformation and locations of jumpers. Also, see the sectionentitled “Checking the Analog Inputs and Outputs”.

Analog Outputs

An Analog Output is the portion of the hardware that theGCU uses to provide control. With ACUair®, this output istypically a 4-20 mA signal that is outputted to an externaldevice. The devices are:

• Pre-Heat

• Cooling

• Variable Speed Fan

• Humidity

Checking the Analog Inputs and Outputs

Some problems that are encountered involvetroubleshooting the Analog inputs and outputs. TheAnalog I/O (Input / Output) Boards have eight Analog I/O(DIO) board connectors labeled P1 through P8. Theexternal Analog devices are wired to a DIO connectorplug. Position 1 connects to the plus (+) of the externaldevice for channel 1, position 2 connects to the signal(SIG) of the external device for channel 1 and position 3connects to ground (GND) of the external device forchannel 1. Position 4 connects to the plus (+) of theexternal device for channel 2, position 5 connects to thesignal (SIG) of the external device for channel 2 andposition 6 connects to ground (GND) of the externaldevice for channel 2, as shown below:

The Analog I/O Boards have numerous jumpers that mustbe properly selected. There are sixteen analog inputchannels that can be selected for 4-20 mA, 0-5 Vdc, orICTD. All of these jumper settings are listed later in thissection (Analog Board Settings section). Besides properlysetting the hardware jumpers, each channel is setup insoftware for the proper transducer type and range, andeach transducer must be calibrated through theappropriate sensor calibration screen. Improper setup ofeither the hardware or software will result in improperoperation or range.

The most common fault associated with the reading of theanalog channels other than hardware or software setupproblems fall into one of the following categories:

• Sensor fault

• Wiring problem

GND

Channel 2+

Channel 1+

Channel 1Signal

Channel 2Signal

GND


• Improper grounding of system.

An open wire, shorted wire, or faulty sensor will usuallygive a reading at either the minimum or the maximum endof the range scale. An erratic reading or a reading thatseems to float up and down is usually indicative of agrounding problem. When a single transducer or cable isshorted to earth (or system) ground, this can show up as awhole assortment of problem channels. The easiest wayto find a short to earth problem is to disconnect all thesensor plugs and ohm out each plug screw terminal toearth for open (infinite) impedance. All sensors shouldread open to earth.

Replacing a Defective Analog Board

The procedure to replace the Analog board is outlinedbelow:

1. Shut off control power.

2. Remove the old board from the machine and thenew board from its packing and place both on ananti-static surface.

3. Remove any required chip(s) from the defectiveboard and install them in the replacement board.

4. Check that all jumpers, dipswitches andcomponents are properly setup on the new boardas it was on the old board.

5. Install the modified replacement board in thepanel.

The Quantum™ controller requires accurately adjustedDC voltages in order to function properly. These voltagesconsist of +5 Vdc, and +12 Vdc (the -12 Vdc and +24 Vdcare not used). Periodic measurement and adjustment ofthe DC power system is highly recommended for optimumsystem operation. Over time, it is possible for temperature,humidity, vibration and component age, to degregate theaccuracy of these voltages. When any of the DC voltagesbegin to stray from their optimum range (especially +5Vdc), mysterious problems can begin to arise.

Condor Power Supply

Both DC voltages originate from the power supply. Referto the Flow Diagrams for the Quantum™ 3 and 4.

Even with a perfectly adjusted supply, it is possible for apotential drop in voltage at each connection point withinthe DC wiring harness. This drop normally is in the mill-volt range, but under some conditions, the drop can bemuch greater (as high as tenths of a volt). By the time thevoltage reaches the Quantum ™, and all of these potentialvoltages drops are considered, the combined drop can besuch that serious problems can be apparent. Someexamples of serious problems could be:

• Quantum™ reboots for no apparent reason.

• LED's on the Quantum™ are lit, but nothingappears on the display.

It must be pointed out that only the +5 Vdc can beadjusted.

In order to properly measure the DC power, it must bechecked at the Quantum™ controller connection. For the+5 Vdc, if the voltage is in the range of +5.04 to +5.08(+5.06 is ideal), it can be assumed that the +5 V power iscorrectly adjusted. For the +12 Vdc, if the range isbetween +11.8 and +12.2 Vdc (+12.00 is ideal), it can beassumed that the +12 V power is correct. Remember thatthe +12 Vdc cannot be adjusted on the Condor.

Measuring and adjusting thepower supply voltages

require the control power switch to be energized. Extremecare must be observed when taking any readings, as 120or 230 VAC (depending on incoming system voltage) ispresent within the power supply. Adjusting the supplyrequires the use of a small screwdriver with an insulatedshaft, refer to NS letter NS-10-02) inserted into the supplyto access an adjusting potentiometer. It is possible for thescrewdriver (and the person making the adjustment) tocome into contact with potentially lethal voltages.

To perform measurements and adjustments on the powersupply voltages, use a reliable Digital Volt Meter (DVM).The DVM should be accurate to 1/100 of a volt DC. Withthe control power switch turned "ON", wait until the "AirHandling Unit Overview" screen appears. This is becausethe graphics required to create this screen will draw morecurrent than when the screen is showing the normal"POST" style messages during a boot up. If the screennever appears however (possibly due to a voltageproblem), you will need to proceed regardless of what is oris not displayed.

Ensure that the meter is set to the proper range (DC, 0-50V, or equivalent), as well as observing proper wire polarity.Measure the +5 Vdc first. If you have a Quantum™ 3controller, refer to the pictorial drawing of it on thefollowing page for the exact location of the measurementpoint. Place the negative lead on the common (return) pin,and the positive lead on the +5 Vdc pin as shown. Verifythat the DVM is displaying in the range of +5.04 to +5.08(+5.06 is ideal). If the reading is outside of this range, thenusing a thin, flat bladed screwdriver, insert the tip into theaccess hole for the appropriate voltage potentiometer(refer to the Quantum™ Panel D.C. Power SupplyLayouts). While watching the DVM, slowly rotate thescrewdriver blade clockwise to increase the voltage orcounter-clockwise to decrease.

Check the reading on the DVM. If the reading at theQuantum™ has been adjusted properly, then this readingcan be no lower than +4.98 DC. If the voltage is less,check all of the daisychain connections on the blue DC-I/Oharness. Ensure that all of its connectors are tight. If allconnections are good, then go back and start measuringover again, this time beginning at the first board in thedaisychain. Continue checking the voltage at eachconnection, until you locate the point at which the voltagedrop is excessive. This will usually indicate a connectionthat is not being made properly, or the sockets within theconnector are weak. In either case, the DC wire harnessmay need replacing.

Next, you will want to measure the +12 Vdc. Perform thesame steps as with the +5 Vdc measurement. If thevoltage is low, ensure that there is not an excessivevoltage drop in the wiring harness. If there is not excessiveloss, (and the voltage is low) then the supply itself mayneed replaced.

REPLACEMENT

If the power supply is found to be bad, or not capableof acceptable adjustment, it will need replacing. Whenordering this replacement, you will receive an upgradekit. The purpose of this kit is to allow for the upgradingof the DC power harness, at the same time asreplacing the power supply. Refer to theRecommended Spare Parts list for the upgrade partnumber. This upgrade kit will include the followingcomponents:

• Screws (6-32 x 3/8 flat head)• Power supply (Condor)• DC power cable harness (this is an improved

version of the previous power cable)

IDENTIFYING THE TYPE OF DISPLAYTo date, there have been four different manufacturers ofdisplays that the Quantum™ Control Panel has used. It isimportant to be able to determine the type of display thatyou are installing, so that it can be properly matched withthe version of Quantum™ controller already in place. Thereason for this is that each of the manufacturers has theirown requirements for both logic voltage, and for backlightvoltage for their particular display. Fortunately, theSamsung, NEC, and Sharp displays all share the samevoltage characteristics, only the LG Philips display variesfrom this voltage requirement.

A sticker should be affixed to the top center of themounting plate. This sticker will give the part number ofthe assembly, the display (and type of display), and theinverter. If this sticker is not present, or to confirm thesticker information, measure the distance from one end ofthe white display mounting plate to the other, as shownbelow. If the distance is approximately 12-3/4", the display

that is mounted to the plate is either a Sharp, NEC orSamsung. If the distance is approximately 11-3/4", thedisplay is an LG Philips, as shown below.

Once the type of display is known, you will want to use thechart at the bottom of this page to determine the properparts compatibility.

You will also need to refer to the jumper settings for theappropriate Quantum™ controller that is installed.

Display Replacement

1. Shut off control power.2. Remove the defective display.3. Install the new display.4. Ensure that all parts (cables, etc.) are compatible

per the chart at the bottom of this page.5. Verify the jumper (link) settings per the table near

the bottom of this page.

TROUBLESHOOTING A PROBLEM THAT APPEARS UNEXPLAINABLE

When there is a problem that makes no sense due tounexplainable things happening, then check the following:

� It is important to know if the unit ever workedproperly.

� If the unit used to work properly, try to determinewhen the problem first showed up.

� It is important to know if the problem occursrandomly, frequently, or all the time.

� Check what the temperature is at the panel. Is itvery hot or very cold?

� If it just started to act up, then check if there wasrecently a severe lightning storm, fire, flood, or aplant accident. If any of the following conditionsare possible, then check for it:

� Has any water or oil leaked into the panel orconduit?

� If it just started to act up, then check if anythingwas recently changed in the system (i.e. softwareor hardware.)

� If it just started to act up, then check if anyservice was recently done to the air unit or it’selectrical system?

� If there is communication wiring connecting thepanel to another panel or device, then check thefollowing:

� If the Quantum™ is unexplainably shuttingdown, try disconnecting the communicationscable to see if the problem goes away (thisdoes not affect the individual air unitsoperation).

� Check if the communications cable shieldsare tied to machine ground at only onelocation.

� Check that you are using the Frick®

recommended communications cable. Seemanual to match proper cable with type ofcommunications (i.e., RS-422, RS-232, RS-485, or some other type of factorycommunication bus system.)

� If this is an older plant, has the plant wiring beenbrought up to code?

� Do you have power wiring mixed with controlwiring?

� Do you have power wiring mixed with sensorwiring?

� Do you have power wiring mixed withcommunications wiring?

� Check that the starter panel is grounded to theplant transformer. There are usually four wires: 3

for the 3 phases and 1 for plant ground.

� Check that the motor is grounded to the starterpanel. There are usually four wires: 3 for thephases and 1 for ground.

� Check that the pressure transducers are properlygrounded. The two types of transducers you mayhave are as follows: an older type has an 8 to 10inch 3-conductor pigtail coming out of thetransducer. This type will have the attachingcable’s shield cut off and insulated at thetransducer end. The shield is then tied to a panelground terminal in the panel. The newer type hasthe cable as an integral part of the housing andhas the shield crimped to the case at thetransducer end. This type of transducer has thecable’s shield cut off and insulated in the controlpanel.

� Check that the temperature transducers areproperly grounded. The temperature probesusually have two short wires coming out of thesensor, and are tied to a shielded cable at thethermal well head. The shield is insulated at thetemperature probe and grounded at the panelend.

� Check if one of the temperature probes has asignal wire shorted to machine ground. To dothis, first pull the orange plug from the microboard and then use a DVM and check each whitewire to machine ground and each black wire tomachine ground.

� Check that all inductive loads (i.e. Coils,Solenoids, or Relays, etc.) connected to the I/Ooutput modules have surge suppressers acrossthem, preferably at the devices and not at thepanel end.

� If the air unit control settings unexplainablychange modes, it may be a noise problemaffecting the keypad’s input circuit. Check if itworks OK with the keypad cable disconnected. Ifit works OK, then check the grounding asdescribed above. If the grounding is OK thenreplace the keypad.

� Make sure that you have a continuous groundback to the power source. The ground connectionmust be aluminum or copper. A conduit groundwill not work.

� Make sure that there is no AC wiring lying next tothe printed circuit board.

� Unexplainable auxiliary failures are usuallyindicative of noise due to wiring problems (i.e.incorrect earth grounds, mixed power and controlwiring, unsuppressed coils, etc)


SETPOINT DATA SHEETSIn most cases, updating software on the Quantum™ panel will require clearing the current setpoints and data stored in thenonvolatile memory on the main board. It is suggested that the operator first record all control setpoints prior to performingprogram chip upgrades. Panel Setup and Factory Setup settings will be lost when software is updated. The setpoint datasheets are useful for recording this information.

The ACUair® product consists of either of two types of air handling units, Makeup Air, or Mixed Air. Because of the twoavailable types, this section will address each type separately, as each may have different setup screens based upon theinstalled options. Be aware that not all of the items shown here may be depicted on your individual unit. These screens are anattempt at showing all possible options that can be enabled.
