X6: Input „Through / reflective photo cell“ resp. light curtain
Photo cell
A photo cell is used for presence detection. It is only active in door operating modes ".3" and
".4", in the OPEN final limit position or during the CLOSE-operation.
If the light beam is interrupted, fault indication "F2.1" appears.
Light curtain
The light curtain must be self-testing and correspond at least to safety category 2 or
performance level c (plc). If the light curtain corresponds to these requirements, the door can
close into self-hold without safety edge system.
Important!
▶ Operation without safety edge: Connect resistor 8K2 via the terminals X2/3 and
X2/4
▶ Photo cells must not be used via the UBS system if a light curtain is used
▶ Do not use menu item "3.2" for the light curtain
To test the light curtain, activate relay contact X20.
The relay functions are described under menu item "2.7" / "2.8".
If the light beam is interrupted, fault indication "F4.6" appears.
A testing is carried out with every CLOSE-command. Thereby the contact of the light curtain
must switch off within 100 ms. If the test is positive, the contact must switch back on within
300 ms. If the test is negative, the fault indication "F4.7" is displayed.
To reset fault indication "F4.7": Switch control off and on.
Note!
Only use photo cells or light curtains with "Light switching" mode
