Motion 4000
Table 5.1 Status and Error Messages
MCSB INPUT FAILURE
Description: The Car Stop Bypass Monitor (MCSB) input on the HC-CTL board is active while the car stop
bypass circuit is not active.
Troubleshooting:
1. Verify wiring and connections at ESC and SAFC.
2. Temporarily disconnect then reconnect the CAN connection to the HC-CTL board to reset the micropro-
cessors.
3. Verify that SPA, SPB, and SPC LEDs are all lighted.
4. If this failure occurred while updating software, refer to the update instructions and repeat the process.
MDZLV INPUT FAILURE
Description: The Door Zone/Leveling Monitor (MDZLV) input has detected a failure of the Door Zone/Lev-
eling (DZLV) or (DZLVA) outputs or failure of the normally open DZ relay.
Troubleshooting: Replace relay DZ.
MGB INPUT FAILURE
Description: Gate switch bypass circuit failure detected.
Troubleshooting:
1. Toggle gate bypass switch on HC-CTL board a few times, make certain it is fully in ON or OFF position.
2. Briefly disconnect then reconnect CAN connection to CTL board to reset processors.
MGBR INPUT FAILURE
Description: Rear gate switch bypass circuit failure detected.
Troubleshooting:
1. Toggle gate bypass switch on HC-RDR board a few times, make certain it is fully in ON or OFF position.
2. Briefly disconnect then reconnect CAN connection to RDR board to reset processors.
MGS INPUT FAILURE
Description: The Gate Switch Monitor (MGS) input has detected a failure of the gate switch or Door Zone/
Door Zone Leveling (DZ/DZLVA) circuitry.
Troubleshooting:
1. Check gate switch condition.
2. Replace relay GS.
3. Replace relay DZ.
4. With doors locked, check continuity between IDC terminals GS1 and GS2 on the HC-CTL board.
5. If rear doors are present, check GSR.
MGSR INPUT FAILURE
Description: The Rear Gate Switch Monitor (MGSR) input (test point TP48 (GSR2) on the HC-RDR board)
has detected a failure of the rear gate switch or Door Zone/Door Zone Leveling (DZ/DZLVA) circuitry.
Condition 1: MGSR should be low during automatic operation when either the rear gate or rear hoistway
doors are open as indicated by the GSR and DLR relays, except during re-leveling.
Troubleshooting:
1. If either relay GSR or DLR is not picked, verify that TP48 is low.
2. Check continuity between terminals GS1 on the HC-CTL and GSR1 on the HC-RDR board and between
terminals GS2 on the HC-CTL and GSR2 on the HC-RDR board.
Condition 2: If the car is re-leveling, and the front doors are closed, the MGSR input should have 120VAC.
Troubleshooting: Check continuity between terminals GS2 on the HC-CTL board and GSR2 on the HC-
RDR board.
Condition 3: This fault is also generated if relays GSR and DLR are picked, indicating that the rear gate
and hoistway doors are closed, but the MGSR input is low.
Troubleshooting:
1. Verify relays DLR and GSR are both picked.
2. Verify 120VAC on terminals GSR1 and GSR2.
3. Verify 120VAC on TP49 (MDLR) on the HC-RDR board.
4. Verify 120VAC on TP48 (GSR2) on the HC-RDR board.
