Description
Cause:
This is a warning for an incorrect starting sequence.
Troubleshooting :
The possible reasons for this alarm are (use the readings
in the TESTER to facilitate the troubleshooting) :
A) A travel demand active at key on
B) Presence man sensor active at key on
Check the wirings. Check the micro-switches. It could be
also an error sequence made by the operator. A failure in

A failure in the logic is possible too; so when all of the
above conditions were checked and nothing was
found, replace the ACE logic board.
Cause :
This alarm occurs when both the travel demands (Fwd
and Bwd) are active at the same time.
Troubleshooting :
Check the wiring of the Fwd and Rev travel demand
inputs (use the readings in the TESTER to facilitate the
troubleshooting). Check the microswitches for failures.
A failure in the logic is possible too. So, when you have
verified the travel demand switches are fine working and
the wiring is right, it is necessary to replace the controller.
