Connect the pack to a 100–240Vac source. No fuse exchange is required.

o

Maximum distance from the power pack to each antenna is about 10.7m (35').

Whenever possible, keep the pedestals from noise sources such as computer monitors, TV’s, switching power supplies, and neon displays.

DO NOT install pedestals more than 2m (6.5') apart.

If crash posts are to be used, locate each post inside the facility and no further than 15cm (6") from the edge of the pedestal.

Cables from the pack to the pedestals can run along the floor through Wiremold or run below the floor through conduit made of galvanized rigid steel. Minimum trade size of conduit shall be 1/2" unless otherwise specified.

Maximum distance from the power pack to each alarm unit is about 7.6m (25').

Plug the transformer used to power the alarm into a 24 hour, unswitched outlet.

Referring to system layout illustrations on pages Q-2 and Q-3, mark the proper placement of system components and accessories on a floor plan blueprint or note pad. Make your notations clear and concise since you will need to reference them during the actual installation. Be sure to inform the customer of your decisions.

Testing for Proper OperationProcedure

Pack

Psion

Comms Link Cable

Remove the four screws from the test point cover to access the test points. Then, connect a scope to the A-TXI and B-TXI test points and verify that the waveform amplitude is approx. 8 amps. peak (each volt increase represents 1 amp). If not, refer to page Q-8 (EuroPro•Max) or Q-11 (Low Cost).

After connecting the transmit, receive, and alarm cables, turn the pack back on. Verify that the LED’s cycle correctly, and that the pedestal alarm audio and lamp do not activate. If not, see “Section 4.0, Service”.

Turn the Psion programmer on and initiate the INTL program that begins on page Q-15. (For general operating instructions on the use of the Psion programmer, see “Appendix A.”)

Verify that the system will monitor current data by selecting the Get Sys Data option (page Q-18).

Turn the pack off and disconnect the Psion programmer. Also disconnect the scope probes and reattach the test point cover.

Unless otherwise directed, make sure that the alarm parameters have not been set for silent operation.

Wave an active tag or label in front of one pedestal. The audio alarm and lamps should activate. Repeat this step for the other pedestal.

1.

2.

3.

6.

9.

10.

11.

Verify that you have Psion data pack (9TOL-0562-02, Rev. E) installed. If so, connect the Psion programmer to the pack.

Temporarily change a few parameters, then verify that the system will download those parameters (see pages Q-16 and Q-17).

4.

Pack Test Point / LED Board

“As shipped” default settings should be optimum for most noise environments. However, the system may have to be adjusted should any of the following conditions occur:

Recommended Adjustments

Noise closely mimics a tag signal—Increase detects for a hit to decrease the chance for an alarm event (but doing so may make the system sluggish).

Bandpass filter output is clipping—Move the noise source or decrease the receiver gain setting from 3 to 2 (or 1).

Noise spikes are initiating validation sequences—Using the VAL test point on the test point / LED board, increase the minimum average setting until only a few validation sequences initiate every 5 to 10 seconds.

Zone protection—Set the lamp and audio configuration settings, and the external alarm configuration setting, if used, to “independent.”

5.

Make sure that the signal at the BP (bandpass) OUT test point for each channels is not clipping. If it is, relocate the noise source or use the Psion to decrease receiver gain.

Basic Signal Checks


AC Line Checks

At the ac outlet, check the voltage between ac neutral (large slot) and ground. If 115Vac is meas- ured, hot and neutral could be wired backwards.

Equipment Required

Dual channel oscilloscope with BNC input for current check

x10 scope probe.

•

•

DO NOT use lines having more than 0.5V between ac neutral (large slot) and ground.

DO NOT use ac lines dedicated for computer equipment.

Adjusting for Noise Interference


In-band noise present in the environment or out-of- phase magnetic field bursts can cause the pack to set off a false alarm or ignore tag ring down. There are three basic types of in-band noise, all of which are characterized with respect to receive windows. These are continuous wave noise, impulse noise and rolling noise.

Continuous Wave (CW) Noise

To configure the receive coils for a vertical figure-8, move the receive cable from connector J1 to connector J2 on the diff. amp. board.

A figure-8 scheme is when upper and lower receive coils are wired so that the magnetic flux generated by a distant signal source induces an equal but opposite current in each coil. Thus, when the system sums the two currents, the signal from the distant source is reduced.

Impulse Noise

The ability for impulse noise to initiate a validation sequence improves when the noise average is low. This is because a signal that meets the SNR requirement when the noise average is low may not meet the requirement when the noise average is high.

For example, as shown below, during store hours when the noise average is high, lets say 7µV (meas- ured at the antennas), a noise spike of 10µV does not surpass the programmed SNR of 12dB. However, after store hours, when the average noise is low, lets say 2µV at the antennas, spikes of 10µV will surpass the 12dB SNR. This means the algorithm will initiate the validation sequence frequently (desensitizing the system), and increasing the chance for a false alarm.

Keep this concept in mind when switching from the default setting for SNR and minimum noise average.

Rolling Noise

In-Band Noise

Usually from a single source and present in all receive windows, this noise is best eliminated at its source. However, if this can’t be done, the noise can be compensated for by wiring each pedestal’s top and bottom receive coils into a vertical figure-8 phase canceling scheme.

Impulse noise may appear in the same receive window, or in different windows from day to day. The pack compensates for this noise by sequentially sampling each receive coil/phase combination and maintaining a noise average for each. If the noise average of one receive channel is above the others, then that channel’s ability to successfully initiate the validation sequence is reduced.

This noise appears periodically throughout the day in any one of the three receive windows or in all. The system compensates for this noise by sampling in- band noise in line phase A, B and C at a repetition rate of 75/90Hz.

Out-of-Phase Magnetic Field Bursts

Ac line phasing other than 0°, 120° or 240° can cause one pack’s burst to be detected by another as a tag signal. Use potentiometer R61 on the pack of the offending system to bring its burst back into proper phase.

LED Error Indications


No LED’s light.

Remove the lid from the power pack and check cable 0650-0772-01 and cable 0650-0773-01 going from the PFC/main supply board to the low voltage supply board. Also check the cable 0650-0775-01 going from the low voltage supply to the pedestal interface board. For cable locations, see pages Q-23 through Q-25.

Red LED’s do not light up solid after initial flickering.

Power pack software did not boot or system application software never executed.

Yellow LED’s do not light up steadily.

All LED’s lit. Pack failed the line frequency test.

Only the yellow LED’s light.

Transmitter failure interrupt signal caused by too great a change in the delay in the 0XING signal, incorrect bias timing, or by power amplifier components overheating.

Only one of the two green LED’s light.

If only the Ch. A or B LED lights, then the problem is likely caused by an analog gain failure in its associated receiver channel.

Both green LED’s light steadily.

Symptom Probable Cause Suggested

Loose power cord, blown fuse, or loose power supply cable.

Check for a loose power cord.

Check for signals on the test point / LED board. If signals are absent, then check for a blown fuse (see page Q-46).

1.

2.

3.

If steps 1 through 3 do not solve the problem, then replace the PFC/Main and/or low voltage power supply boards.

Problem is likely on the pedestal interface board (page Q-33). Check that the cable connections to the board are tight and check that its jumpers are correctly positioned. If they are, then replace the board. Note: If the pack does not

completely boot up, it will attempt to reboot approx. every 15 seconds (as controlled by the watchdog timer on the pedestal interface board).

- or -

Problem is likely on the transmitter interface board (page Q-35) or power amplifier board (page Q-37). Check that cable connections to both boards are tight and check that their jumpers are correctly positioned. If they are, then turn the pack’s power switch off and on. If the yellow LEDs come on immediately, replace the transmitter interface board. If they come on after a period of time, replace the power amplifier board.

- or -

Problem is likely on the receiver board (page Q-43). Check that the cable connections to the board are tight and check that its jumpers are correctly positioned. If they are, check INT on the test point / LED board. If this signal is incorrect or absent, or if receiver gain is not 98dB (±3dB), replace this board.

Check the transmitter interface cable (0650-0774-01) from the PFC/Main supply to the transmitter interface board. Be sure that LVAC1 (23Vac) is at TP15 on the transmitter interface board (page Q-35). Also check LS' on the test point board. If LVAC1 is wrong or absent, replace the PFC/Main supply. If LS' is wrong or absent, replace the transmitter interface board.


Accessing Power Pack PCBs


To access PC boards, remove the ten screws from the cover, then lift the cover off and set it aside.

To access PFC/main and low power supply boards, remove the seven screws securing the end panel and drop the panel down.

To access pedestal interface, receiver, or transmitter interface boards, remove the board’s bracket screw and carefully unplug it and lift it out. To test these boards, use an ISA compatible 16-bit extender card.

To replace the power amplifier assembly, remove these four screws. DO NOT DETACH THE PC BOARD FROM THE HEAT SINK.

Replacing a Fuse


The fuse is located in the Power Entry Module, which is part of cable assembly 0650-0763-01.

To replace a fuse is simple. Insert a small slotted screwdriver into the slot at the top of the fuse cartridge to nudge it so that your fingers can grab it and pull it out. Then use the same screwdriver to gently remove the fuse.

The M2000 power pack uses two identical 250V, 3A slow-blow fuses; one for the line side and one for the neutral side. If either fuse blows, the pack will not operate.

Reinstall the cartridge such that the 220–240V designation faces the marking on the face of the Power Entry Module.

WARNING—TO REDUCE THE RISK OF FIRE, REPLACE ONLY WITH A 250V, 3A, SLOW-BLOW FUSE.

Pry out cartridge.Remove and replace blown fuse with same type and rating.

3. Reinsert cartridge with 220–240V designation facing marking on module.



Figure-8'ing the Transmit Coils

To configure the transmit coils for a vertical figure-8, do the following:

On the transmitter wiring harness for the EuroPro•Max (shown) or the “Low Cost” pedestal, use a Molex extractor tool to move the wire in pin 1 to pin 3 in the 5-pin Molex connector.

Move the jumper from pins 2 and 3 to pins 1 and 2.

Aligning the Zero-Crossing Signal


To verify that the zero-crossing signal is properly aligned to the actual zero-crossing of the line frequency, perform the following procedure:

Switch off the power pack and unplug it from the ac outlet.

Procedure

Remove the ten screws from the cover of the pack and set the cover aside.

Remove the seven screws from the end panel that hold the PFC/main supply board (0301-0450-01) to enable the board to lay next to the pack. Refer back to page Q-32.

Connect the Channel A probe of an oscilloscope to pin 1 of inductor L2 on the PFC/main supply board. This is the pin closest to the right-hand corner of this board.

Connect the Channel B scope probe to the 0XING test point on the test point / LED board.

Synchronize the scope to Channel B.

Plug in the power cord and switch on the power pack.

Adjust the scope to view the positive-going edge of the zero-crossing signal and the positive-going edge of the zero-crossing of the ac signal.

Note. Use the AC-GRND-DC switch on Channel A to obtain the true zero-volt reference.

Using a non-conductive tuning tool, adjust R30 on the transmitter interface board (0301-0355-01) until the zero-crossing of the ac signal is aligned with the positive-going edge of the zero-crossing test point (±30 µsec.).
