Developer Data Trap Triggered
Description: Custom data trap has detected event to save relevant fault information to BBRAM. The informa-
tion for ten events is stored. Additional events overwrite the information for the oldest event.
Dispatcher = Car ‘n’, DISPATCHER = CAR’n’ (n = 1 to 15)
Description: Communication with the main iCue dispatcher has been lost or not established. This car is com-
municating with Car 'n' (n = 1 to 15) which is acting as the backup dispatcher.
Troubleshooting: Check the group to car communication related connections and parameters.
Door Lock Clipped Greater than 200fpm, DOOR LK CLIPPED G200
Description: The door lock signal (DLAT, DLMS, DLAB, or GS) went low for over 300mS while the car was
moving at over 200 fpm.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Tro ubleshooting:
1. Use Event Log to determine where fault occurred. Examine the locks in that area of the hoistway first.
2. Usually caused by a misadjusted door, where the pickup rollers do not have adequate running clearance
from the door clutch.
3. Because this fault must persist for over 300mS, a slight “bumping” of the door lock will not set it off. If
the door clutch/pickup roller clearance is adequate, make sure the door contacts are clean and the door
lock mechanism drops cleanly without friction or binding.
Door Lock Clipped Less than 200fpm, DOOR LK CLIPPED L200
Description: The door lock signal (DLAT, DLMS, DLAB, or GS) went low while the car was moving at under
200 fpm.
Car Reaction: ASAP stop.
Tro ubleshooting:
1. Usually caused by a misadjusted or damaged door. Because it only occurs at speeds under 200 fpm, it is
usually seen when the car leaves the floor where the problem door is located.
DOOR LOCK OPENED
Description: Status message indicating safety processor has detected open door lock. A fault is generated if
car is moving or attempts to move while door lock open.
Down Direction Limit Open, DOWN DIR LIMIT OPEN
Description: Down normal terminal direction limit switch is open.
Car Reaction: Initiate an immediate stop if moving. Further down direction movement is prevented.
Tro ubleshooting:
1. Verify that the switch is operating properly.
2. Verify correct state of the iBox DNTD input.
3. Verify DNTD switch is activating/deactivating at correct location (normally 2” below bottom terminal.
Down Emergency Terminal Switch Position Fault, DN ETS POSITION FAULT
Description: Reported position upon encountering Terminal Switch differed from learned position by more
than set position margin. This fault may be bypassed on the Diagnostics > Fault Bypass tab.
Car Reaction: Emergency Stop: Motor contactor and brake contactor immediately dropped. All hall and car
calls canceled. After car is stopped, it will run at Correction speed to next available floor and cycle door. Door
Open button will remain operational. If fault generated when car is moving, fault will stay latched and Fault
Reset button must be pushed to clear it. If generated when car is not moving, fault will self clear when con-
dition no longer exists.
Tro ubleshooting:
1. Physically check the integrity of the switch and wiring.
2. Check the iBox input for the switch.
3. On the Diagnostics > Terminal Switches Status tab, compare the last pass position against the learned
position for this switch. Verify that Position Margin is within a reasonable range. Relearn the NTS and ETS
switches. Please refer to “Learning Normal & Emergency Terminal Limit Switches” on page 4-12.
