X6: Input, "Through / reflective photo cell" or 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 closing 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. If the light
curtain corresponds to these requirements, the door can close into self-hold without safety
edge system.
Important!
▶ Operation without safety edge system: Connect 8K2 resistor via terminals X2/3
and X2/4
▶ Photo cells must not be used via the UBS system
▶ Do not use menu "3.2" for the light curtain
▶ To test the light curtain, activate relay contact X20 or X21.
For a description of the relay functions see menu "2.7" or "2.8".
If the light beam is interrupted, fault indication "F4.6" appears.
Testing is carried out at each CLOSE command, 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 fails (is negative), fault indication "F4.7" appears.
▶ To reset fault indication "F4.7": Switch control off and on.
Note!
▶ Only use photo cells or light curtains with "Light switching" mode
