IMP Switch Fault - Write Enable, IMP SW FLT: WRITE EN
Description: There is a problem with the iBox WRITE ENABLE switch. Both poles must activate.
Car Reaction: None
Tro ubleshooting:
1. Sometimes the switch fault can be temporarily cleared by toggling the switch multiple times.
2. The iBox slide switches can be repaired using MCE part: IMP-SW-JUMPER-KIT.
Independent Service, Independent Svc
Description: Indicates that the Independent Service switch has been activated.
Car Reaction: Car and door operation in accordance to user-defined settings for independent service. (iView/
Car Operation/Independent Service.) Car does not respond to hall calls.
Tro ubleshooting:
1. If reported in error, check the Independent Service switch and wiring.
Inspection Operation, Inspection
Description: The car is operating in Inspection mode.
Car Reaction: One of the inspection modes (in-car, machine room, or cartop) is active. The car will operate
using the Inspection performance pattern.
Inspection Overspeed Fault
Description: While operating in Inspection mode, the car exceeded the Inspection Overspeed setting on the
iView Safety Configuration screen.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Tro ubleshooting:
1. The fault will automatically clear 5 seconds after the car stops. The car is then allowed to run again.
2. If reported in error, check the Inspection Overspeed setting on the Safety Configuration screen.
3. Check the iView event log for any events immediately preceding the overspeed fault.
4. Determine and correct the cause of the overspeed.
Insufficient Brake Feedback Fault, INSFCNT BRK FDBK FLT
Description: Brake current feedback is abnormally low.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Tro ubleshooting:
1. Check DB-25 connector from iField module to iBox is seated properly.
2. Check power supply on brake iField module.
3. Verify all wiring connections on the brake (BK) contactors are properly terminated and conducting.
4. Verify brake voltage parameters.
5. If used, verify iField Module setting for terminals FMCI and FMHC. Please refer to “IFIELD-MODULE-L Ter-
minals on the ICE-FM Board (Brake Module)” on page 6-100.
6. Verify that the brake is properly calibrated. Please refer to “Calibrating Actual Car Speed (System 12 SCR
Drive)” on page 2-38. Please refer to “Brake Parameter Adjustments” on page 4-27.
7. Check Brake voltage on the Operational Status tab. If the value goes below 0.00 volts, and/or the drive
offset (Input ADC) was recently calibrated or adjusted, verify / set the Input ADC = 0.0 on the Configu-
ration > Drive > Calibration tab.
Insufficient Motor Field Feedback Fault, INSFCNT MF FDBK FLT
Description: Indicates that Motor Current Feedback signal is less than 50% of the commanded field current.
Car Reaction: If detected four times over seven runs the car will shut down.
Tro ubleshooting:
1. Check motor field AC supply off isolation transformer.
2. Check connections from controller to motor.
3. Check connections to iField motor module.
