Safety switch CES-AR
Benefits for you
- Possible to connect up to 20 safety switches in series
- Integrated short circuit monitoring by pulsing
- Large actuating range
- High level of protection against tampering
- Adjustable actuating head with 5 approach directions (only housing C01)
- Mounting compatible with standard housing according to EN 60947-5-2 (only housing C01)
- Diagnostics using LED
The small design of the actuator and switch makes mounting on the guard easy.
Design and functionality
The safety switches are connected together using connectors. The CES-AR-... has two safety outputs. In a switch chain, the signals from the safety outputs are connected to the next switch. The outputs on the last switch in the chain are connected directly to drives, downstream safety relays or safe control systems. The switch monitors itself for short circuits using pulsed signals. External clock signals are not allowed (see next section).
Indication for actuator in the limit range
If the safety door with the actuator should settle over time, the actuator can drift out of the read head actuating range. The device recognizes this and indicates that the actuator is in the limit range (function available from V 1.1.2 and higher). This allows the safety door to be readjusted in time.Connection to safe control systems or safety relays
Do not use a control system or safety relay with pulsing for monitoring short circuits or switch off the pulsing function in these devices. The switch generates its own clock signals on the output lines OA/OB. A downstream device must tolerate these test pulses, which may have a length of up to 1 ms.The inputs on the downstream device must be suitable for positive-switching devices (pnp outputs), as the two outputs on the safety switch deliver a level of +24 V in the switched-on state.
OUT output
The semiconductor output OUT is switched if the guard is closed (actuator in the actuating range). It is not allowed to be used for safety functions. The OUT outputs on the individual switches can, however, not be polled if connected in series using a Y-distributor. Evaluation is possible only on parallel wiring to the control cabinet.RST input
The switches in a chain in a fault state can be reset using the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 seconds. It is not necessary to disconnect the power supply to reset a fault.Use as individual switch or switch chain
The safety switch CES-AR can be operated as a compact individual switch or in a switch chain with max. 20 devices.
If a single CES-AR is used, connect the switch as shown in figure above. The OUT output can also be connected here to a control system as a monitoring output.

The switches are connected in series using plug connectors and Y-distributors.
The first switch in the chain must always be fitted with a bridging plug. If a safety door is opened or if a fault occurs on one of the switches, the system shuts down the machine. A higher-level control system can, however, not detect which safety door is open or on which switch a fault has occurred. A special AR evaluation unit is required.
