86 Door Test Error
If the lift starts for a target floor without completing
door open test at that floor successfully then this error
is created.
Cause
Troubleshooting
1. Parameter B56 refer to the door test procedure. This parameter
defines if the door will make a self-check at every opening or
only at first opening. if this procedure fails then check the KL1-
KL2 and AL1-AL2 commands on the door mechanism.
2. If the error insists with the commands working properly, then
the error appear at first startup. if the door drive loses power
supply, it makes itself a width learn before normal operation.
this procedure happens with slow speed to the door drive,
so the door commands from the board do not have the time
to reset the door mechanism. in this case, increase the door
opening time [C04] DOOR OPEN PERIOD-1 for door A or [C34]
DOOR OPEN PERIOD-2 for door B and try to make the open-
ing and closing time of the door motor faster.
