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 TROUBLE-
SHOOTING IS REQUIRED.
2.
Remove the test shunt. The RX1 (RX2) Occupancy LED
should light. If the RX1 (RX2) Occupancy LED fails to
light, 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.
3.
To calibrate the Crossing Assembly Island (ISL),
proceed to Section 7.4.1.3.
Island Calibration Procedures
1.
Temporarily connect a hardwire shunt across the
track at the appropriate distance beyond the island
receiver rail connections as specified in the hardwire
shunt distance chart of Table 7-2 (0.12, 0.3, 0.4 and
0.5 ohms).
2.
Scroll down the Main Menu until CAL appears on the
display. Then:
•
Press the MENU Button for two (2) seconds until
ISL CAL appears.
•
Hold the MENU Button down until the release
(REL) message appears. Release the MENU Button
immediately once the release (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) seconds, the calibration
process cancels and the calibration process must
be restarted.
•
*ISL 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, see the
WARNING below.
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

THEN REPEAT STEP 2 ABOVE. IF “FAIL”
APPEARS AGAIN, FURTHER TROUBLE-
SHOOTING IS REQUIRED.
3.
Remove the hardware island shunt. The Island
Occupancy LED should light. If the Island Occupancy
LED fails to light, 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.
4.
Review the face of the PSO 4000 Crossing Assembly.
In the Calibration section, the green RX1, RX2, and ISL
LEDs are lit, indicating that the circuits have been
calibrated. In the Occupancy section the red XR, RX1,
RX2 and ISL LEDs are lit, indicating that the circuits
are not occupied.
5.
Once the Island has been calibrated, proceed to
Crossing Assembly Checkout Procedures, Section
7.5.2.
Crossing Assembly Checkout Procedures
1.
Scroll down the Crossing Assembly Main Menu until
INFO appears on the display.
2.
Scroll down the sub-menu one step until “+RX1 SIG
LVL =” appears on the Display.
3.
Take note of RX SIG LVL. This 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.
5.
In the WSS containing the transmitter for the receiver
1 (RX1) track circuit, remove the transmitter’s signal
to the track by disconnecting a transmitter lead from
the track surge equipment.
6.
On the Crossing Assembly, take note of the Signal
Level. If the Signal Level is greater than 20, an
unintended signal of like frequency is present.
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 RESOLVED.
7.
Verify that the RX1 and XR indicator LEDs found in
the Occupancy portion of the face of the unit de-
energize. If the LEDs fail to de-energize, replace the
unit.
8.
Restore the receiver 1 (RX1) track circuit Transmitter
signal to the track by reconnecting the lead in the
transmitter’s track surge equipment.
9.
Verify that the RX1 and XR indicator lights found in
the Occupancy portion of the face of the unit
energize. If the LEDs fail to energize, replace the unit.
10.
Press and release the NAVIGATE button. “+RX2 SIG
LVL =” appears on the Display.
11.
In the WSS containing the transmitter for the receiver
2 (RX2) track circuit, remove the transmitter’s signal
to the track by disconnecting a transmitter lead from
track surge equipment.
12.
Repeat Steps 5 – 9 for receiver 2 (RX2), then proceed
to Step 13.
13.
Momentarily press the MENU Button and release it.
“+ISL SIG LVL =” appears on the Display.
14.
Take note of the Signal Level
15.
Remove the Island Transmitter signal to the track by
opening one of the wires that runs to the rail
connection.
16.
Take note of the Signal Level. If the Signal Level is
greater than 20, an unintended signal of like
frequency is present.
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 RESOLVED.
17.
Verify that the Island and XR indicator LEDs found in
the Occupancy portion of the face of the unit de-
energize. If the LEDs fail to de-energize, replace the
unit.
18.
Once the unintended signal has been removed,
restore the Transmitter signal to the track by
reconnecting the wire that runs between Pin 9 of the
Lower 10-pin Connector and the surge equalizer at
the Surge Panel.
19.
Verify the Island and XR indicator lights found in the
Occupancy portion of the face of the unit energize. If
the LEDs fail to energize, replace the unit.
20.
Verify proper operation of the track circuit
equipment before placing in service in accordance
with railroad or agency procedures and applicable
FRA rules.
21.
Verify proper PSO 4000 operation by observing train
moves, per railroad or agency policy.
22.
The system is now ready for operation.
