9. Press and hold the MENU Button for approximately
two (2) seconds until TLVL=XXXX (e.g., TLVL=LOW)
appears. Transmitter programming is complete.
10. Press and hold the MENU button for approximately
two (2) seconds. The top level menus displays PSO+
XXXX TX (Code) (e.g., PSO+ 4000 TX A) appears in the
4-Character Display in four letter segments.
CONFIGURE PSO+ RECEIVER:
1. Observe the face of the Receiver. Either DIAG is
flashing or PSO+ XXXX RX (Code) (e.g., PSO+ 645 RX
C) scrolls in the 4-Character Display.
2. If desired frequency appears in the window, proceed
to CALIBRATE PSO+ RECEIVER. If PSO+ XXXX RX
(Code) (e.g., PSO+ 645 RX C) shows the wrong
frequency in the 4-Character Display, proceed to step
4. If DIAG is flashing, proceed to step 3.
3. If DIAG is flashing, press and hold the MENU button
for approximately two (2) seconds. DIAG stops
flashing. Navigate to the RFRQ menu. Press and hold
the MENU button for approximately two (2) seconds.
NONE flashes in the 4-Character Display. Proceed to
step 5.
4. If PSO+ XXXX RX (Code) (e.g., PSO+ 645 RX C)
appears in the 4-Character Display and the frequency
is not the desired frequency, press and hold the
MENU button for approximately two (2) seconds. The
currently selected frequency (e.g., 645) flashes in the
4-Character Display.
5. Press and hold the MENU button for approximately
two (2) seconds. The currently programmed
frequency or NONE appears. Press the DATA button
until the desired frequency appears, then press and
hold the MENU button for approximately two (2)
seconds. SET RFRQ = XXXX? (e.g., SET RFRQ=156?)
appears.
6. Press and hold the MENU Button for approximately
two (2) seconds until RFRQ=XXXX (e.g., RFRQ=156
HZ) appears. Receiver programming is complete.
7. Press and hold the DATA button for approximately
two (2) seconds. The top level menus displays PSO+
XXXX RX (Code) (e.g., PSO+ 156 RX C) appears in the
4-Character Display in four letter segments.
CALIBRATE PSO+ RECEIVER:
1. Observe face of PSO+ Receiver. Verify the Calibration
Required (Cal Req) LED is on.
2. 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 beyond the receiver track
connections. Verify solid connections of the shunt to
each rail.
3. To Calibrate the Receiver
•Navigate to the CAL menu.
•Press the MENU Button until *CAL appears.
Release the MENU Button. The calibration
process begins.
•*CAL and CAL alternately flash during the
calibration process.
•PASS or FAIL appears for twenty (20) seconds
when calibration is complete. When PASS
appears, continue to Step 4. If FAIL appears, the
CALIBRATION REQUIRED LED remains lit and
DIAG will flash on the 4-Character Display.
WARNING
IF “FAIL” APPEARS ON THE DISPLAY, THE
CALIBRATION REQUIRED LED REMAINS
LIT, OR THE RELAY DRIVE (RLY DR) LED
DOES NOT LIGHT, THE CALIBRATION
PROCESS DID NOT COMPLETE. SHOULD
THIS HAPPEN, CYCLE THE UNIT POWER
AND THEN REPEAT STEP 3. IF THE UNIT
FAILS TO COMPLETE THE CALIBRATION
PROCESS, FURTHER TROUBLESHOOTING IS
REQUIRED.
4. Remove the test shunt. The Cal Req LED should go
out. If Cal Req LED does not go out, the calibration
process has failed (refer to the WARNING above).
Inspect all equipment and connections and repeat
steps 1 & 2. If the calibration fails again, further
troubleshooting is required.
5. The RLY DR LED should light once the test shunt has
been removed. If not, proceed to Appendix B,
Troubleshooting.

INSTALL PSO+
TRANSMITTER/RECEIVER MODULES
Document Number SIG-QG-10-07
Version B.1
The following procedure should be used when installing
Phase Shift Overlay Plus (PSO+) Track Circuits utilizing
PSO+ Transmitter, 7A481 and PSO+ Receiver, 7A483.
WARNING
VERIFY THAT THE PSO+ TRANSMITTER’S
AND RECEIVER’S SOFTWARE, FREQUENCY,
AND ADDRESS FORMATS ARE AS
SPECIFIED BY THE RAILROAD’S OR
AGENCY’S APPROVED DESIGN. FAILURE
TO DO SO MAY LEAD TO INCORRECT OR
UNSAFE OPERATION OF THE TRACK
CIRCUIT.
IF ANY RECEIVER IS CALIBRATED IN POOR
BALLAST CONDITIONS, IT MUST BE RE-
CALIBRATED WHEN BALLAST CONDITIONS
IMPROVE.
FAILURE TO FOLLOW THE RAILROAD’S OR
AGENCY’S APPROVED DESIGN REGARDING
RECEIVER SETTINGS AND CALIBRATION
MAY LEAD TO POSSIBLE UNSAFE
OPERATION OF THE TRACK CIRCUIT.
AFTER CALIBRATION, VERIFY THAT THE
TRACK CIRCUIT DE-ENERGIZES WHEN THE
TRACK CIRCUIT IS SHUNTED WITH THE
APPROPRIATE CALIBRATION 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
6-4 AND TABLE 6-5 OF SIG-00-10-16, PSO+
I & I MANUAL.
INSTALL PSO+ UNITS
1. Install and connect all PSO equipment per the
railroad’s or agency’s approved design.
2. Connect all required wiring per the railroad’s or
agency’s approved design.
CONFIGURE PSO+ TRANSMITTER:
1. Observe the face of the Transmitter. Either DIAG is
flashing or PSO+ XXXX TX (Code) (e.g., PSO+ 645 TX
A) scrolls in the 4-Character Display.
2. If desired frequency appears in the window, proceed
to step 7. If PSO+ XXXX TX (Code) (e.g., PSO+ 645 TX
A) shows the wrong frequency in the 4-Character
Display, proceed to step 4. If DIAG is flashing,
proceed to step 3.
3. If DIAG is flashing, press and hold the MENU button
for approximately two (2) seconds. DIAG stops
flashing. Navigate to the TFRQ menu. Press and hold
the MENU button for approximately two (2) seconds.
NONE flashes in the 4-Character Display. Proceed to
step 5.
4. If PSO+ XXXX TX (Code) (e.g., PSO+ 645 TX A)
appears in the 4-Character Display and the frequency
is not the desired frequency, press and hold the
MENU button for approximately two (2) seconds. The
currently selected frequency (e.g., 645) flashes in the
4-Character Display.
5. Press and release the DATA button until the desired
frequency appears, then press and hold the MENU
button for approximately two (2) seconds. SET TFRQ
= XXXX? (e.g., SET TFRQ=4000?) appears in the 4-
Character Display.
6. Press and hold the MENU Button for approximately
two (2) seconds until TFRQ=XXXX (e.g., TFRQ=4000
HZ) appears. Shortly afterward, the Transmit Level
(TLVL) setting appears.
7. If the written instructions state that currently
depicted transmit level will be used, proceed to step
10; transmitter programming is complete. If the other
setting will be used, press and hold the MENU button
for approximately two (2) seconds. The current value
(e.g., HIGH) flashes in the 4-Character Display.
8. Press the DATA button until the desired value (e.g.,
TLVL=LOW) appears. Press and hold the MENU
button for approximately two (2) seconds. SET TLVL =
XXXX? (e.g., SET TLVL=LOW?) appears in the 4-
Character Display.
