Short circuit monitoring
The switch generates its own clock signal on the output cables OA/OB.
Pay attention to this aspect when connecting to control systems and relays.
Each actuator is unique. The switch detects only taught-in actuators. Additional actuators can be taught in. Only the last actuator taught in is detected.
Category according to EN 13849-1
Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4/PL e according to EN 13849-1
Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated.

Approach directions
Typical operating distance
(Actuator CES-A-BLN… in conjunction with safety switch CES-AR-C.2-… in case of mounting on plastic)
For a side approach direction for the actuator and safety switch, a minimum distance of s = 6 mm must be maintained so that the operating distance of the side lobes is not entered.
Attention:
The operating distance may vary depending on the background material and installation situation.
