Stalled Fault
Stop Switch Fault
SU I/O Failed Off
SU I/O Failed On
SUF I/OFailed Off
Description
Stall Fault occurs if the
motion run timer
exceeds the stall
protection time. The
motion run timer is
incremented while the
car is trying to run.
Stop switch is pulled
while the car is in
motion.
The SU input or
output has failed off
The SU input or
output has failed on.
The SUF input or
output has failed off.
Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• The elevator may have stalled from an improper valve
adjustment. Verify the valve adjustment during high speed
and leveling in both directions.
• Increase Stall Timer on the controller under Adjustable
Variables and Car Timers. Set the timer to allow the car to
run the entire hoistway at the recovery speed.
• The recovery speed parameter may need to be increased
to 50 fpm or higher. Typically, do not set higher than 80
fpm. If the recovery speed parameter has been changed.
Run the car in between floors on inspection and then return
the car to automatic. Verify that the car recovers to a
landing without overshooting the
floor.
• Stop switch is pulled.
• Faulty wire connection in the stop switch circuit.
• Faulty SUi input. Swap input board to see if SUi input chip
is bad and replace input board if necessary.
• The SU solenoid is shorted to GND at the SU terminal.
Refer to the schematic and check the circuit with a meter.
• Faulty SU output. Swap the output with another device to
verify if the output is bad and replace if necessary.
• Faulty SUi input. Swap input board to see if SUi input chip
is bad and replace input board if necessary.
• The SU test jumper was left on the output after an I/O
test. Remove test jumper.
• Voltage back feed through the SU coil. Verify that the SU
solenoid is connected to the solenoid common. Refer to the
schematic and check the circuit with a meter.
• Faulty SU output. Swap the output with another device to
verify if the output is bad and replace if necessary.
• Faulty SUFi input. Swap input board to see if SUFi input
chip is bad and replace input board if necessary.• The SUF
solenoid is shorted to GND at the SUF terminal. 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.
