Man

This key acts as a software switch. If the feeder operating mode is Grav and this key is pressed, the operating mode becomes Vol. and vice versus. For PID applications the Auto/Man function is used.

NEW SP

This key, when pressed, allows you to change the operating Setpoint of the feeder if control mode is Local or Ratio. In the Ratio mode, the ratio percentage is entered. This key functions regardless of where you are in the Feeder Overview screens or Menus. The following display appears:

SETPOINT 600.00 kg/hr

New = Type in the new setpoint and press the ENTER key. The display will say "Accepted" if O.K. and revert to the Feeder Overview screen. If Range Error is displayed, the display will not change.

TOT 000

This key, when pressed, displays the totalizer. To clear, enter <0>. To preset the totalizer to a number other than zero, enter than number. This key functions regardless of where you are in the Feeder Overview screens or Menus.

This key, when pressed, takes you to the Main Menu screen where you can select from the various menus available, i.e. New Material Menu Alarm Menu Scale Menu, etc. Note: Use the Next key to select the Menu desired

NEXT

This key allows you to scroll thru the available Feeder Overview screens, Menus and selections within the Menus. ( Note : Use the "C" key to back-up in the listing)

ENTER

The ENTER command accepts an entered value or command, and sends the message to the controller board.

RUN

This key commands the feeder to Run. Note: A setpoint must be entered, all permissives must be satisfied and no Alarm shutdown present in order for the feeder to Run.

765.7 KSU Operation



LED function

The following table provides information on the operation of the display single point leds.

LED Function

This green LED is activated when the controller is in RUN mode. For a system with a speed pickup, this is LED is active when the controller has speed feedback. For systems without speed feedback, the LED is activated by the drive enable signal.

This Red LED is active when the controller is in STOP mode. For a system with a speed pickup, this LED is active when the controller has no speed feedback. Note: These LEDs can also be used as a power on indicator. When the STOP Led is On and the RUN is flashing, it means that the feeder is ready to run and that only the “RUN” button needs to be pressed. If the lights are not flashing alternatively, and the Stop led alone is on, the machine may be missing a key variable or has an interlock set that would prevent the machine from running if the “RUN” key was pressed.

) This Red LED is used to indicate a controller alarm is present. When the alarm is first detected, the alarm LED will light. When the alarm timer expires, the alarm LED will flash to indicate alarm timeout. With this, the status line will also blink.

This Yellow LED will be active when the controller is operating in the Local setpoint control mode. This mode indicates that the setpoint is entered via the keypad in the selected engineering units. This led is not lit for other Control modes, i.e. Ratio, Direct, Line 1-8.

765.8 KSU Operation


KSU Operation

Intro

This section outlines KSU operation. Information is presented in an hierarchy of menus with the most important, operational data presented on the overview menu which is displayed upon start-up. You can reach this menu by pressing the “Home” key. The KSU allows programming of all parameters required to configure and operate the feeder system.

Menu layout

The menus are laid out in a format as shown. You will use the menu and arrow keys to open and work with the menus shown here. In addition, some menus use sub-menus to permit more choice selection and flexibility for editing data.

Power-up sequence

When power is applied to the controller, the following screen appears for approximately 20 seconds after a series of bars is displayed and then the Feeder Overview Screens appear.

Alarm Handling

Intro

This section demonstrates how alarms are handled by the display.

Alarm handling concepts

The following graphic is designed to show what happens in an alarm sequence. Note that first an alarm condition must be present and is indicated by an illuminated ALARM Led. Once the Alarm Delay Timer expires the ALARM Led begins to blink and the Alarm Relay drops out setting your external alarm enunciator. If you are in the Feeder Overview Screen the display line 1 begins to alternate between normal and a blank line. Pressing the ALARM Key acknowledges the alarm. Pressing the ALARM key a second time, clears the alarm. If you in a Menu or special function ( Alarm screen, Totalizer screen or New SP screen ) the display does not change. The only visual indication of an Alarm is the Alarm LED.

Procedure to acknowledge and clear an alarm

To view the alarm screen, acknowledge the alarm and clear the alarm the following procedure should be followed:

Step Action 1 When the alarm led blinks, and the first line of the Feeder

Overview screen blinks, press the ALARM key. 2 The following screen will then appear:

A L A R M S

The initial press of the “Alarm“ key also acknowledges the alarm. Note that an alarm number also appears. This helps to correctly identify the alarm problem.

3 The key must be pressed a second time to clear the alarm. This key functions regardless of where you are in the Feeder Overview screens or Menus.



Programming Security Measures

Intro

This section shows how to set program security measures with the KSU.

Security levels

There are three levels of security that can be set on the KSU display unit. This is in the Security Lev Sub-Menu in the System Main Menu. These are, in the order of access:

Operator – "Oper” Manager – “Mgr” Maintenance – “Main”

To make alterations to the values of the security permissive in the System menu, a switch, connected to the security input (rear of KSU) must be closed. When opened, the Security menu is not changeable. See document 6020 for details on this hardware connection.

Procedure to program the security level

Step Action 1 Open the System menu and Security Lev Sub-Menu. 2 Select the desired protection: Oper, or Mgr, or Maint in the

Security Level Variable and press “Enter”. See the check note in step #3 if the value cannot be changed.

3 To lock the Security menu, a bit input to the KSU must be set to prevent change.

If this bit is locked, no alteration to the Security permissive is permitted.
