WARNING

IF “FAIL” APPEARS ON THE DISPLAY, THE CALIBRATION REQUIRED LED (LEFT COLUMN) REMAINS LIT, OR THE CALIBRATED LED (RIGHT COLUMN) DOES NOT LIGHT, THE CALIBRATION PROCESS DID NOT COMPLETE. SHOULD THIS HAPPEN, CYCLE THE UNIT POWER AND THEN REPEAT STEP 2 ABOVE. IF “FAIL” APPEARS AGAIN, FURTHER TROUBLESHOOTING IS REQUIRED.

3. Remove the test shunt. The RX Occupancy LED should

light. If the RX Occupancy LED fails to light, the calibration process has failed (refer to the WARNING above). Inspect all equipme nt and connections and repeat steps 1 & 2. If the calibration fails again, further troubleshooting is required.

4. The RX Occupancy LED should light once the test

shunt has been removed. Repeat steps 1 – 4 for the OT2 Receiver. When the O T2 RX Occupancy LED lights, proceed to Receiver and Tra nsceiver Checkout Procedures, Section 7.5.1.

Receiver and Transceiver Ch eckout Procedures

1. On the OT1 Transceiver, scroll down the Main Menu

of the Receiver until INFO appears on the display.

2. Momentarily press the MENU Button and release it.

“+RX SIG LVL =” appears on the Display.

3. Take note of RX SIG LVL. T his is the normal receive

signal value. Verify the RX SIG LVL value is >300. If not, set TX LVL to High and perform calibration and checkout procedures again. If the value remains below 300 after selecting TX LVL=High, select a lower frequency where RX SIG LVL value is >300.

4. In the WSS containing the transmitter, remove the

transmitter’s signal to the track by disconnecting a transmitter lead from the track surge equipment

5. On the receiver, take note o f the Signal Level. If the

Signal Level is greater than 20, an unintended signal of like frequency may be pr esent.

WARNING

DO NOT PROCEED TO STEP 6 AND BEYOND UNTIL THE UNINTENDED SIGNAL OF LIKE FREQUENCY IS NO LONGER PRESENT (THIS MAY REQUIRE A FREQUENCY CHANGE TO AVOID UNINTENDED HARMONICS.) THIS CONDITION MUST BE RE SOLVED.

6. Verify that the RX LED found in the Occupancy

portion of the face of the unit is de-energized. If the LED remains lit, troubleshoot the unit.

7. Restore the Transmitter signal to the track by

reconnecting the lead in the transmitter’s track surge equipment.

8. Verify that the RX LED found in the Occupancy

portion of the face of the unit energizes. If the LEDs fail to light, troubleshoot the unit, re-calibrate, and perform Steps 1 - 7 again. When the unit passes, repeat steps 1 – 8 for the O T2 Receiver.

9. Verify proper operation of the track circuit

equipment before placing in service in accordance with railroad or agency procedures and applicable FRA rules.

10. Verify proper PSO 4000 operation by observing train

moves, per railroad or agency policy.

11. The system is now ready for operation.

QUICK REFERENCE GUIDE

INSTALL PSO 4000 TRANSCIEVER

MODULE AS REPEATER

Document Number SIG-QG-10-04

Version A.1

The following procedure should be used when installing Phase Shift Overlay 4000 (PSO 4000) Track Circuits utilizing PSO 4000 Transmitter, 7A471, PSO Receiver, 7A473, and PSO Transceiver Assembly, 7A475.

WARNING

VERIFY THAT THE PSO 4000 RECEIVER’S, AND TRANSCEIVER ASSEMBLY’S SOFTWARE, FREQUENCY, AND ADDRESS FORMATS ARE AS SPECIFIED BY THE RAILROAD’S OR AGENCY’S APPROVED WIRING OR INSTALLATION DIAGRAM. FAILURE TO DO SO MAY LEAD TO INCORRECT OR UNSAFE OPERATION OF THE TRACK CIRCUIT.

IF ANY RECEIVER IS CALIBR ATED IN POOR BALLAST CONDITIONS, IT MUST BE RECALIBRATED WHEN BALLAST CONDITIONS IMPROVE.

FAILURE TO FOLLOW THE R AILROAD’S OR AGENCY’S APPROVED WIRING OR INSTALLATION GUIDELINES REGARDING RECEIVER SETTINGS AND CALIBRATION MAY LEAD TO POSSIBLE UNSAFE OPERATION OF THE TRACK CIRCUIT.

AFTER CALIBRATION, VERIFY THAT THE TRACK C IRCUIT DE-ENERGIZES WHEN THE TRACK CIRCUIT IS SHUNTED WITH THE APPROPRIATE CALI BRATION RESISTANCE (0.06, 0.2, 0.3, 0.4, OR 0.5 OHMS). FAILURE TO DO SO MAY LEAD TO INCORRECT OR UNSAFE OPERATION OF THE TRACK CIRCUIT.

FOLLOWING INSTALLATION OR AFTER ANY RECEIVER MENU CHANGES HAVE BEEN MADE, RECALIBRATE THE RECEIVER AND TEST FOR PROPER OPERATION PER THE REQUIREMENTS SPECIFIED IN TABLE 7-2 AND TABLE 7-3 OF SIG-00-07-06, PSO 4000 I & I MANUAL.

Perform the following steps to install the PSO 4000 un its:

1. Install and connect all PSO equipment in the Wayside

Signaling Station (WSS) per the railroad’s or agency’s approved wiring or installation diagram.

2. Connect all required wiring per the railroad’s or

agency’s approved wiring or installation diagram.

3. Prior to beginning programming, verify LED

functionality using the *CHECK LED portion of the TEST menu per Section 5.2.7.2. If any LED fails to light following test, replace the unit.

4. Program each unit by performing Set to Default. Then

proceed through the setup (SETP) menu to program each unit per the railroad’s or agency’s approved written instructions.

With each unit properly installed and programmed per written instructions, calibrate the OT1 PSO Transceiver Assembly, 7A475 receiver (RX) as follows:

1. When the track ballast is good, connect a track test

shunt (hardwire, 0.06-ohm, 0.2-ohm, or as required) across the track at the receiver track connections. When the ballast is poor, connect the shunt across the track at a point 30 feet b eyond the receiver track connections. Verify solid connections of the shunt to each rail.

2. Scroll down the Main Menu until CAL appears on the

display. Then:

• Press the MENU Button for two (2) seconds until

RX CAL appears.

• Hold the MENU Button down until the release

(REL) message appears. Release th e MENU Button immediately once the releas e (REL) message appears.

• As soon as the MENU button is released, the

armed (ARMD) message appears. Immediately press and release the MENU Button as soon as the ARMD message appears. This starts the calibration process. If the MENU Button is not pressed within two (2) seco nds, the calibration process cancels and the calibration process must be restarted.

• *RX CAL flashes during the calibration process.

• PASS or FAIL appears for two (2) seconds when

calibration is complete. When PASS appears, continue to Step 3. If FAIL appears, the CALIBRATION REQUIRED LED remains lit
