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. Return the toggle to OFF.
Note: If the locomotive bell begins to sound it is an indication that the main reservoir is
below 75-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 105-psi main reservoir
pressure in reached. Now activate the RESET button.
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.
¾ 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.
¾ 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.
¾ 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.
If Trainline Braking option is installed:
¾ For systems utilizing the J1 relay valve for trainline, place the trainline isolation valve to
the REMOTE position.
¾ For systems utilizing the 26L brake cover for trainline, place the trainline dump valve to
the OPEN or REMOTE position.
The remote control system now has primary control of the locomotive.
