Description
The MC input or
output has failed off.
The MC input or
output has failed on.
The Middle Door Lock
failed on while the
door was open.
Emergency motion
exit from inspection
MRAM Fault
MRAM Write Error.
After parameter data
RAM has been
modified through the
user interface, the
data is automatically
written to MRAM for
non-volatile storage.
After the data is store
it is compared with
the original parameter
data. If it does not
match a fault is
recorded.
Section 6 – Main CPU Faults & Detailed Faults
Possible Cause/Suggested Fix
• Faulty MCCi input chip. Replace input chip.
• Faulty MCC output chip. Replace output chip.
• No Power at the MRSW terminal. Refer to the schematics
and check the circuit with a meter.
• Faulty MCi input chip. Replace input chip.
• Faulty MC output chip. Replace output chip.
• Faulty door lock.
• Jumper on door lock circuit.
• Door lock not adjusted properly.
• Faulty wiring to DLM input.
Faulty DLM and DLM-1 inputs (For this to occur both DLM
and DLM-1 inputs must fail on).
• DOL input failed. Replace DOL input chip.
• Door operator open limit DOL is not adjusted properly
• Car was in motion before going in inspection Mode. Check
for inspection inputs faulting out or Automatic input going
low.
• The car inspection switch was turned on while the car was
on automatic and in motion.
The MRAM is tested on power up and has failed the test.
Replace the CPU board.
• This error should not occur. If it does occur, the problem
is either a fault CPU board or MRAM chip. Replace the CPU
board.
