Table 6.1 Status and Error Messages
Scrolling Message - Special Event Message
FIRE SERVICE PHASE 1 - ALTERNATE
Description: The car is returning to an alternate fire return landing. The FRS input is low, the FRA
input is high or FRAON is active.
Troubleshooting: Inspect the fire sensors (especially the main floor sensor) and the Fire Phase I
switch wiring. For some fire codes including ASME, the Fire Phase I switch must be turned to the
BYPASS position and then back to OFF to clear the fire service status once activated.
FIRE SERVICE PHASE 1 - MAIN
Description: The car is returning to the main fire return landing. The FRS input is low or the FRON
or FRON2 inputs are high.
Troubleshooting: Inspect the fire sensors and the Fire Phase I switch wiring. For some fire codes
including ASME, the Fire Phase I switch must be turned to the BYPASS position and then back to
OFF to clear the fire service status once activated.
FIRE SERVICE PHASE 2
Description: The FCS controller input is ON.
Troubleshooting: Inspect the phase 2 switch and wiring. In some cases, to exit Fire Service
Phase 2, the car must be at the fire floor at which Fire Phase 2 was activated, the doors must be
fully open, and the phase 2 switch must be off (the FCOFF input must be activated) to get out of
6
phase 2.
FRONT DOL AND DLK ARE BOTH ACTIVE
Description: A critical failure has caused both the Door Open Limit and Door Lock inputs to both
be active at the same time.(DOL=0 & DLK=1). A problem with DOL and/or DLK circuitry or wiring.
Troubleshooting: Inspect the Door Open Limit and the Door Lock circuitry and wiring. When this
error is generated, the car will shutdown with the doors open and will not answer any calls. The
only way to reset this error condition is to put the car on Inspection operation.
FRONT DOOR FAILED TO CLOSE
Description: Doors Open (DCL = 1). There is a problem with DCL circuitry or wiring.
Troubleshooting: Inspect the Door Closed Limit circuitry and wiring. When this error is gener-
ated, the car is not allowed to run.
FRONT DOOR IS LOCKED BUT NOT FULLY CLOSED
Description: Doors Open (DCL = 1) and Locked (DLK = 1). A problem with DCL and/or DLK cir-
cuitry or wiring.
Troubleshooting: Inspect the Door Closed Limit and the Door Lock circuitry and wiring. When this
error is generated, the car is not allowed to run.
FRONT DOOR LOCK SWITCH FAILURE (NYCHA)
Description: The front door lock contacts have failed closed.
Troubleshooting: Ensure that with the front hoistway doors closed and locked, there is power on
the DLS input and no power present on the DCL input.
FRONT DOOR OPEN LIMIT FAILURE
Description: The door open limit switch has failed open.
Troubleshooting: Ensure that the car gate is open, there is no power on the DOL input and no
power is present on the DL or GS inputs.
FRONT GATE SWITCH FAILURE (NYCHA)
Description: The front car gate switch has failed closed.
Troubleshooting: Ensure that with the front car gate closed, there is power on the GS input and
no power present on the DCL input.
