Pneumatic safety edge
The input is designed for a pressure-wave switch system (NC) with a terminal resistance of
1k2 (+/-5 % and 0.25 W). The pressure wave switch system needs to be tested with final limit position CLOSE.
The test phase is initiated by pre-limit switch S5 (automatically for DES). If no switching signal is generated at
the pressure wave switch within 2 seconds, the test is negative and fault indication F 2.8 appears.

When the pneumatic safety edge is activated or the current circuit is permanently interrupted, fault
indication F 2.6 appears. Fault indication
F 2.7
appears in case of a short circuit.
Light curtain (with an OSE interface only)
The input is intended for a light curtain with an OSE interface. The light curtain detects people and obstacles
without contact.

X2 - Door safety switch
You can connect a door safety switch for a pass door or slack-rope switch to terminals X2.1/2.2. The door
safety switches are connected to a safety circuit with Performance Level c (PLc) according to ISO 13849-1. The
safety circuit requires an overall terminal resistance of 5k0 for line cross-circuit monitoring.
Examples of door safety switches are shown below. Connect your product accordingly.
Mount the product according to the manufacturer's instructions.

When activated while the door is moving, the door stops and fault indication F 1.2 appears.
When the switch fails, fault indication F1.7 is displayed.
In the case of a line cross
circuit, fault indication
F1.8
