MUSE INPUT IS LOW (CTLA) (Hydro only)
Description: The MUSE input monitors the continuity of the Up Slow Valve coil and also checks the
OFF state of the USE triac.
Troubleshooting:
1. Check the termination of the valve coil at terminal USE on the HC-DVR board.
2. Check terminal US for 120VAC with respect to 1 bus.
NORMAL OPERATION
Description: The elevator is on “automatic” or Normal passenger operation.
NORMAL (PIT FLOOD) OPERATION
Description: The elevator is on “automatic” or Normal passenger operation with the pit flood input
active. In this mode, the car will not serve floors beneath the flood level set. Please refer to “FLR
COUNT BELOW FLOOD LEVEL?” on page 5-53.
Troubleshooting:
If pit flood operation is in error, refer to the drawings for the job and verify the PTFLD input is cor-
rectly configured (connected/disconnected/connected in error).
OIL TANK TEMPERATURE SHUTDOWN
Description: The input that monitors the Oil Tank Temperature Switch is activated.
Troubleshooting:
1. Verify that the oil is overheated. If it is not, determine if the sensor is activated erroneously.
2. Check the OTTS Spare Input to determine if it is the proper state with regard to the Extra Fea-
tures Menu Option OVER TMP SWITCH CONTACT parameter setting (normally open or normally
closed).
3. To clear the fault condition, on the HC-CTL board, place the car on Machine Room Inspection,
press the FAULT RESET button, then return the car to Normal operation.
OLM INPUT IS LOW
Description: The OLM input monitors the status of the both the thermal overload and the starter
overload contacts. 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 the wiring of the thermal overload between terminals TO1 and TO2 on the HC-DVR
board.
2. Check the wiring of the starter overload between terminal OL1 and OL2 (if present).
OVERLOAD CONDITION
Description: The car appears to be overloaded, as indicated by the load weigher input OVL.
Troubleshooting: Check the OVL input. If power is present on the OVL input, the load weigher
contact associated with this input is closed. This contact being closed indicates to the elevator com-
puter that the car is overloaded.
PASSCODE REQUEST
Description: The Passcode Request Option has been activated from the System Mode Menu.
Troubleshooting: The system can be run on Inspection operation only. The pass code must be
entered correctly in the System Mode Menu in order to deactivate this option and allow the control-
ler to run normally. Please refer to “Passcode Request Menu” on page 5-62.
POWER TRANSFER INPUT ACTIVE
Description: The PTI input has been activated.
Troubleshooting: Go into Program Mode and see if any of the inputs are programmed as PTI.
Then, check to see if that particular input is activated.
