Important: The actuator must be ordered separately. Actuator CET-A-BWK-0X separately Lift tappet with read head 90, CET.-AR...CDA.... For M screw DIN 0 / ISO, 0, With angle connectors Unicode evaluation Each actuator is unique. The evaluation unit detects only the actuator that has been taught-in. Additional actuators can be taught-in. Only the last actuator taught-in is detected. New actuators are taught by connecting the teach-in input to U B (only version with teach-in input). Multicode evaluation Every suitable actuator is detected by the evaluation unit. Mechanical release Is used for releasing the guard locking with the aid of a tool. The mechanical release must be sealed to prevent tampering (for example with sealing lacquer). Escape release (optional) Is used for the manual release of the guard locking from within the danger area without tools. Wire front release (optional) The wire front release permits remote release of the guard locking via a pull rope. Flexible routing of the pull rope permits release of the guard locking in inaccessible installation situations. Solenoid operating voltage DC V +0%, -% Guard locking types CET Guard locking by spring force Release by applying voltage to the guard locking solenoid. CET CET CET Guard locking by solenoid force Guard locking by applying voltage to the guard locking solenoid. Release by spring force. Guard locking by spring force with door monitoring output. Function as for CET-AR, however here the door position is also monitored. The door monitoring output D is set to HIGH as soon as the actuator protrudes beyond the extended lift tappet (state: door closed, guard locking not active). The output D remains set also with guard locking active. Guard locking by solenoid force with door monitoring output. Function as for CET-AR, however here the door position is also monitored. The door monitoring output D is set to HIGH as soon as the actuator protrudes beyond the extended lift tappet (state: door closed, guard locking not active).

14 Miscellaneous accessories Mechanical key release for safety switch CET Emergency unlocking for safety switch CET Cover for safety switch CET Mechanical key release for safety switches CET Mechanical key release The mechanical key release is used in combination with safety switch CET. It enables authorized personnel to actuate the mechanical release using the related key. The unlocking mechanism holds the solenoid in the "unlocked" position. A screw is used to fix the lock to the cover of the safety switch CET (over the mechanical release). The lock is identical locking. 0,, 0 Ø, Order safety switch CET separately keys included (for spare keys see ordering table below) Every safety switch in the CET series can be upgraded with the mechanical key release Emergency unlocking Using the emergency unlocking the safety switch can be unlocked manually. In the locked position of the emergency unlocking, a ball detent mechanism prevents unintentional unlocking of the safety switch due to vibration or similar effects. In the unlocked position of the emergency unlocking, an integrated bolt engages in a bore on the flange. To reset the emergency unlocking, first the bolt must be pressed inwards, out of the detent mechanism, using a tool. Emergency unlocking for safety switches CET 0, Cover With the CET cover, tampering with the safety switch CET is effectively prevented. The cover prevents the use of simple tools to manually press up the actuator.

16 Connection examples CES-AR Important: To achieve the stated category in accordance with EN ISO 9, both safety ( and ) must be evaluated. Connection of a single CES-AR-C If a single CES-AR-C is used, connect the switch as shown in figure below. The output can also be connected here to a control system as a monitoring output. The switch can be reset via the input. To do this, a voltage of V is applied to the input for at least seconds. The supply voltage to the switches is interrupted during this time. If input is not used in your application, it should be connected to 0 V. DC V -F Connection of several CES-AR-C in series The switches are connected in series using plug connectors and Y-distributors. If, in this connection example, a safety guard 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 guard is open or on which switch a fault has occurred. So that a control system can detect the status of each switch in a switch chain, the monitoring output must be connected separately for each switch. A special external evaluation unit is required for this purpose (see page 9). The switches can be reset via the input. To do this, a voltage of V is applied to the input for at least seconds. The supply voltage to the switches is interrupted during this time. If input is not used in your application, it should be connected to 0 V. Important: Switch chains must always be terminated with a bridging plug.

17 Connection examples CET-AR Important: To achieve the stated category in accordance with EN ISO 9, both safety ( and ) must be evaluated. Connection of a single CET-AR, version without feedback loop If a single CET-AR is used, connect the switch as shown in figure below. The output can also be connected here to a control system as a monitoring output. The switch can be reset via the input. To do this, a voltage of V is applied to the input for at least seconds. The supply voltage to the switches is interrupted during this time. If input is not used in your application, it should be connected to 0 V.

To integrate the subsystem in a category or structure, it is necessary to monitor the downstream load (the feedback loop must be monitored). These examples show only an excerpt that is relevant for connection of the CET system. The example illustrated here does not show complete system planning. The user is responsible for safe integration in the overall system.
