Error diagnosis

9.1. Plug-in system controller, interface for
elevator control
The 7-segment display on the plug-in system con-
troller is used as an error, status and diagnosis dis-
play. The numbers 0-9 serve as error indications.
Each number is allocated to a possible error.
The 7-segment display flashes with the respective
error number if an error occurs.
Internal error on plug-in system controller:
Switch off unit, check wiring
-
Activate unit

used for light curtain component diagnosis and error
location.
The following are possible causes of error if error 1 or 2
occur on the plug-in system controller:
1. "Power" LED on
control unit plug-in
does not illuminate!
2.The buzzer sounds
constantly when light
beam is free!
3.How can a light curtain
