4.3 Transfer to Remote Mode and Resetting Locomotive PCS Fault.
To activate the communication link from OCU to locomotive, move the horn toggle to HORN.
The locomotive should respond by sounding the locomotive horn.
Note:
If the locomotive bell begins to sound it is an indication that the main reservoir is
below 60-psi. This could indicate that the isolation valve is in the wrong position.
Recheck the valve and continue with the start up procedure. If the valve is in the
correct position then recharge the main air reservoir. This is accomplished by
placing the directional switch on the OCU in NEUTRAL and increase engine
throttle. Throttle will automatically reduce once the 90-psi main reservoir pressure
in reached. Now activate the HORN toggle.
Release the trainline brake by pressing the AUTO BRAKE toggle switch to the release
position. The command is accepted when the keypad AUTO BRAKE REL indicator turns ON.
Reset the locomotive PCS fault, if required.
• Older systems did not provide an indication of when or if the PCS Fault was activated. If
the system didn’t respond the operator would go to the locomotive and manually reset the
fault.
• On newer systems the locomotive brake status lights are disabled when a PCS Fault is
activated. To recover from PCS Fault the operator simply sounds the horn. When the fault
is cleared the brake status lights should turn on.
• The OCU with two-way communication link will be able to show a PCS Fault message on
the OCU display.)
Ensure the Independent (locomotive) brake valve handle is in the FULL INDEPENDENT
RELEASE position.
WARNING: The remote control system cannot control independent brakes until the
independent brake valve handle is in the FULL INDEPENDENT RELEASE position.
Ensure that the manual headlight switches are OFF, the dimmer switch is set to DIM, the
generator field is ON, and the isolation switch is in the RUN position.
The remote control system now has primary control of the locomotive.
