Faults
Door Zone Off Fault
Door Zone On Fault
DoorZone Aux Off Flt
DPM Input Fault
DPM Off/GS or DL On
DT Failed On Fault
Description
Door Zone Off Fault
occurs when the car
does not have DZ
when UL and DL are
on.
The door zone input
DZ is set from the
count of the APS
selector and the DZ
input did not turn off
during a run.
Door Zone Auxiliary
Off Fault occurs when
the car does not have
DZA/DZAc when UL
and DL are on.
The DPM input fault
occurs when door
opens and the DPM
input did not go off.
DPM Off with Gate
Switch or Door Lock
On.
The Door Protection
Module input must go
on before gate switch
or door lock inputs go
on.
DT I/O Failed On. The
car is on a door zone
and at the bottom
floor but the DT-1
input (from the Main
CPU count) did not
activate (go off).
Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• The DZ/DZp output from the SAFETY PAL comes from the
combination of the following signals: NTS dz output, NTS
communicating with APS selector, Main CPU dz output and
Main CPU communicating with APS selector.• Verify that the
Main CPU and the NTS processor are communication with
the APS selector.• Verify that the Main CPU and the NTS
processor have valid floor tables.
• The APS selector did not change count during a run. Check
for faults related to the APS selector. Verify that the APS
selector counts change while the car is running.
• The elevator did not leave the floor on a run attempt.
Verify that the elevator can run from the landing. Check the
fault log for another fault that could prevent the car from
running.
• Verify that the Main CPU is communicating with the APS
selector.
• Verify that the Main CPU has a valid floor table.
• DPM switch not setup properly on the door operator.
• Faulty DPM input. Replace DPM input chip.
• The DPM switch on the door operator is not setup
properly. DPM should turn on before the Gate Switch is
made.
• There is no DPM input on the door operator. Jump the
DPM input to the GS-1 terminal.
• Fault DPM input. Replace the DPM input chip.
• The down slowdown count for the bottom floor is set
incorrectly. Review the hoistway slowdown table and if this
value is incorrect, relearn the bottom floor position.
