MPI-C UNEXPECTED DIRECTION DROP
Description:
The up or down direction input has dropped while the car is running but is not in leveling
operation.
Troubleshooting
:
Informational only.
MSAFL1 INPUT FAILURE
Description:
The MSAFL1 input monitors SAFL and SAFS relay contacts against the circuits that drive the
relay coils. Bus 2L should be 120VAC and relay SAFL should be picked only if the doors are locked.
Troubleshooting:
1. Check or replace relays SAFL and/or SAFS on the HC-CTL board.
2. Check that IDC terminal 2L on the HC-CTL board connects to IDC terminal 2L on the TC-MPI board.
MSAFS1 INPUT FAILURE
Description:
The MSAFS1 input monitors SAFL and SAFS relay contacts against the circuits that drive the
relay coils. Relay SAFS should be picked only if the safety string is made.
Troubleshooting:
1. Check or replace relays SAFL and/or SAFS on the HC-CTL board.
2. Check wiring associated with screw terminals SAFH, SAFC and ESC.
MSSD FAILED ACTIVE
(Hydraulic Elevators Only)
Description:
MSSD monitors the solid state output of U1 and driver TY for proper operation. If either fail
in the on position, this fault is generated.
Troubleshooting:
1. Check terminal SSD wiring.
MTAB INPUT FAILURE
Description:
The Top Access Bypass Monitor (MTAB) input has detected a failure of the Top Access Bypass
(TAB) or (TABA) outputs.
Troubleshooting
:
1. Verify wiring at HC-CTL board terminals TAB and DLAT.
2. Check access switches and proper wiring of access terminals ATU, ATD.
MTABR INPUT FAILURE
Description:
The Top Rear Access Monitor (MTABR) input has detected a failure of the Top Rear Access
Bypass (TABR) or (TABAR) outputs or the TABR input.
Troubleshooting
:
1. Verify wiring at HC-RDR board terminals TABR and DLATR.
2. Check access switches and proper wiring of access terminals ATU, ATD.
MTBR INPUT FAILED TO ACTIVATE
Description:
The voltage monitored at the TC-MPI board BR triac did not go high when the triac was deac-
tivated.
Troubleshooting
:
1. Check the BR test point. There should be 120V here when the triac is not attempting to pick contactor
BR.
2. Check BR, PM auxiliary contactors, and 2L screw terminal connections and wiring.
MTBR INPUT FAILED TO DEACTIVATE
Description:
The voltage monitored at the TC-MPI board BR triac did not go low when the triac was acti-
vated.
Troubleshooting
:
1. Check the BR test point. There should be 0V here when the triac is attempting to pick contactor BR.
2. Check BR, PM auxiliary contactors, and 2L screw terminal connections and wiring.
