Troubleshooting
5-12 Manual # 42-02-2P24
FCL 1 - 4 - MAIN IGBT STUCK CLOSED
Description: If the brake is not in pick, hold, relevel, or dissipate mode and there is more than 40 volts or
200 milliamps across the brake coil for 200 mS or more, the IGBT stuck closed fault will occur. In CAN
mode, this fault resets automatically after 8 seconds.
Troubleshooting: Check that manual brake pick is not enabled. Please refer to “SW1, Manual Bypass” on
page 5-82.
FCL 1 - 4 - MAIN IGBT STUCK OPEN
Description: If the brake is in pick, hold, or relevel mode and there is less than 20 volts or 100mA across
the coil for 200 mS or more, the IGBT stuck open fault will occur. The car will stop at the next landing. The
first and second consecutive occurrence faults reset automatically after 8 seconds. If the module consecu-
tively faults again, fault “Brake Module Fault Limit Reached” is issued and must be reset on the HC-CTL
board.
Troubleshooting:
1. Check the brake for proper operation according to manufacturer specifications.
2. Verify that the BR contactor supplies the module with sufficient voltage when the Pick command is
sent.
FCL 1 - 4 - MODULE ADDRESS ERROR
Description: A brake module address conflict has been detected. The car will stop at the next destination.
Three consecutive occurrence faults reset automatically after 8 seconds. If the module consecutively faults
again, fault “Brake Module Fault Limit Reached” is issued and must be reset on the HC-CTL board.
Troubleshooting: Verify SW3 positions for each module. Please refer to “SW3 Module ID and Software
Features” on page 5-83.
FCL 1 - 4 - MODULE OVERHEAT
Description: The IGBT units on the bottom of the TC-FCP board generate heat when operating. A thermal
sensor on the heat sink is connected to the module logic board through the TS1 and TS2 inputs. If the tem-
perature becomes excessive, the logic module will generate a fault, pulling the FLT output to the Common
connection level and alerting the controller.
Troubleshooting:
1. The fault will reset when the module cools.
2. If this is a recurring event, check the brake for proper operation. Check that brake pick and hold volt-
ages are correct. Please refer to “FCL Power Data Menu” on page 4-116.
FCL 1 - 4 - NOT CALIBRATED
Description: The addressed module is not calibrated to operate with the Motion 4000 system.
Troubleshooting: Calibrate the module. Please refer to “Calibration (CAN Only)” on page 5-87.
FCL 1 - 4 - TRYING TO RUN IN MANUAL RELEASE MODE
Description: Module is in manual release mode and the controller is attempting to run the car which
involves operating the brake.
Troubleshooting: Disable manual release mode. Please refer to “SW1, Manual Bypass” on page 5-82.
FIRE SERVICE PHASE 1 - ALTERNATE
Description: The car is returning to an alternate fire return landing. The FRS input is low and the FRA
input is high or FRAON is active.
Troubleshooting: Inspect the fire sensors (especially the main floor sensor) and Fire Phase I switch wir-
ing. For some fire codes, including ASME, the Fire Phase I switch must be turned to the BYPASS position
and then back to OFF to clear the fire service status once activated.
