5-86 Manual # 42-02-1P28 A3
LS-EDGE POSITION ERROR (264) Description: Initiated by the LS-EDGE-EL landing system. LS-EDGE has
detected a previously learned floor zone or terminal magnet outside learned
position margins. If moving, the car will perform an emergency stop. If
stopped, the car will not be allowed to move. Bypassed in Construction
Bypass mode.
Troubleshooting:
1. Verify magnet positions.
2. Repeat hoistway learn operation (Utils > Landing System Utilities >
Hoistway Learn (Landing System Learn).
LS-EDGE: ACCESS OVRSPD (339) Description: LS-EDGE has detected an overspeed while operating on
hoistway access.
LS-EDGE: INSPECT OVRSPD (340) Description: LS-EDGE has detected an overspeed while operating on
Inspection mode.
Troubleshooting:
1. Verify Inspection Overspeed setting (CONFIG02 > System Control
Parameters > Inspection Overspeed).
2. Verify Profile Scale setting (CONFIG02 > System Control Parameters >
Profile Scale).
M2L INPUT FAILURE (602) Description: The M2L input monitors the status of the relay contacts of
SAFL and SAFS against the circuits that drive these relay coils. Bus 2L
should be 120VAC and relay SAFL should be picked only if the doors are
locked. 2MV bus must also be active.
Troubleshooting:
1. Check or replace relays SAFL and/or SAFS on the HC-CTL-2 board.
2. Verify that IDC terminal 2L on the HC-CTL-2 board connects to IDC ter-
minal 2L on the HC-DVR board.
3. Check the thermal overload wiring between terminals TO1 and TO2 on
the HC-DVR board.
4. Check the wiring of the starter overload between terminal OL1 and OL2
(if present).
5. Replace the HC-DVR board.
M2L IS LOW (121) Description: 2LS bus unexpectedly low. Cannot be bypassed.
Troubleshooting:
Verify fuse F2MV on SCE-UPD board.
M2MV IS LOW (120) Description: 2MV Bus (120VAC) monitoring input is low. Cannot be
bypassed.
Check fuse F2MV on the SCE-UPD board.
Verify 120VAC across terminals X1B and X2B on the SCE-UPD.
MABGF INPUT FAILURE (470)
MABGR INPUT FAILURE (501)
Description: The (Front/Rear) Access Gate Bypass Monitor (MABGF/R)
input has detected a failure of the Access Bypass Gate A (ABGA/R) or
Front/Rear Access Bypass Bottom (FABB/RABA) outputs.
Troubleshooting: Replace the HC-RDR board
MABT INPUT FAILURE (477) Description: The Top Access Bypass Monitor (door close contacts) (MABT)
input monitors proper operation of the solid state devices associated with
bypassing the top hoistway door contacts during access operation.
Troubleshooting:
Remove the car from access operation and verify that test point TP33
(MABT) on the HC-CTL-2 board is low with respect to 1 bus. If not, contact
MCE for assistance.
