Faults
SUF I/O
Failed On
SUF I/O On
Fault
Top Door Lock Fault
Trace Trigger
UL and DL Off Fault
Description
The SUF input or
output has failed on.
SUF I/O Failed on
when stopped at the
floor.
The Top Door Lock
failed on while the
door was open.
The Data Trace has
been triggered. This is
not a fault
Both UL and DL level
inputs are off when
car is at a floor. These
two inputs are set
from counts from the
APS selector.
Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• Faulty SUFi input. Swap input board to see if SUFi input
chip is bad and replace input board if necessary.
• The SUF test jumper was left on the output after an I/O
test. Remove test jumper.
• Voltage back feed through the SUF coil. Verify that the SUF
solenoid is connected to the solenoid common. Refer to the
schematic and check the circuit with a meter.
• Faulty SUF output. Swap the output with another device to
verify if the output is bad and replace if necessary.
After the car stops at the floor and the RUN output drops,
the SUF and SDF I/Os are check to verify that they have
turned off.
• Verify that the LED on the output module has turned off.
If not then replace the output module.
• Check for voltage on the solenoid terminal. If there is no
voltage then replace the appropriate input board.
• If there is voltage on the solenoid terminal, remove the
output module. If the voltage goes away with the removal of
the output module, replace the output module.
• Faulty door lock.
• Jumper on door lock circuit.
• Door lock not adjusted properly.
• Faulty wiring to DLT input.
• Faulty DLT and DLT-1 inputs (For this to occur both DLT
and DLT-1 inputs must fail on).
• DOL input failed. Replace DOL input chip.
• Door operator open limit DOL is not adjusted properly
• Verify that the Main CPU is communicating with the APS
selector.• Verify that the Main CPU has a valid floor table.
