OLM INPUT FAILURE (603) Description: The OLM input monitors the status of the both the thermal
overload and the starter overload contacts. Bus 2L should be 120VAC and
relay SAFL should be picked only if the doors are locked. 2MV bus must also
be active.
Troubleshooting:
Check that IDC terminal 2L on the HC-CTL-2 board connects to IDC termi-
nal 2L on the HC-DVR board.
Check the wiring of the thermal overload between terminals TO1 and TO2
on the HC-DVR board.
Check the wiring of the starter overload between terminal OL1 and OL2 (if
present).
Replace the HC-DVR board.
OLM INPUT IS LOW (604) Description: The OLM input monitors the status of the both the thermal
overload and the starter overload contacts. Bus 2L should be 120VAC and
relay SAFL should be picked only if the doors are locked. 2MV bus must also
be active.
Troubleshooting:
Check the wiring of the thermal overload between terminals TO1 and TO2
on the HC-DVR board.
Check the wiring of the starter overload between terminal OL1 and OL2 (if
present).
Replace the HC-DVR board.
OUT OF SERVICE (39) Description: The COS Timer has elapsed subsequent to the Car Delayed
Timer having already elapsed. Fault-bypassed in Construction/Inspection.
System Verifies: - Car Flags - Car Out of Service
Troubleshooting:
Determine the cause of the delay.
See Car Delayed for additional information.
OVERLOAD (44)
OVERLOAD 2 (45)
Description: Car is loaded beyond overload setting. Buzzer will sound and
car will not leave floor until load is below the setting. Not generated in con-
struction operation. Bypassed by FRS.
Troubleshooting:
If in error, verify no input is programmed for the Load Over function.
Otherwise, calibrate load weigher.
Verify status of input and input wiring.
PARAMETER RANGE FIT (239) Description: When loading stored parameters, some parameters did not
pass the valid range check. This message is not necessarily a problem but
parameter verification is recommended. This may occur when:
Changing software.
If a parameter is corrupted.
Using parameter files with different versions.
PARAMETER STORAGE FAULT (118)Description: A fault occurred while parameters were being stored. Cannot
be bypassed. The car will not be allowed to move.
Troubleshooting:
If fault occurred while updating software, reset processor C, repeat soft-
ware update.
If fault does not clear, see error code under STORAGE ERROR (MOTION
DIAG>MOTION NUMERIC). Contact MCE.
PASSENGER MODE (0) Description: Passenger mode active.
