Monitoring of the machine contact
2 ways of monitoring are selectable:
Mode 1
In this mode the access to the LC must only be done when the machine
contact has been openend and closed again. An exception is when the
access is done while the contact is open and still is going on while the
contact closes.
Forbidden access into the light curtain
On forbidden access the lamp (on terminal 58) shows symmetric fl ashing.
The lamp on terminal 48 fl ashes with code 1. After fi nishing the access the
lamp on terminal 58 returns to permanent light and signalises, that the
machine can be started with the start button.
