Operating Instructions Safety System CES-AP-C.2-AH About this document This document is valid for all safety switches CES-AP-C.2-AH with version number V 1.1.2 or higher. Correct use The Coded Electronic Safety switches of series CES are safety devices for monitoring movable safety guards. In combination with a separating safety guard and the machine control, this safety component prevents dangerous machine movements from occurring while the safety guard is open.

Operating Instructions Safety System CES-AP-C.2-AH If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance. The device recognizes this and indicates that the actuator is in the boundary area (function available for V 1.1.2 and higher). This allows the safety door to be readjusted in time.
Operating Instructions Safety System CES-AP-C.2-AH Mounting Caution! Risk of damage to equipment as a result of incorrect installation. Safety switches must not be used as a mechanical end stop. ÌÌFit an additional end stop for the movable part of the safety guard. Important: ÌÌFrom the assured switch-off distance Sar, the safety outputs are safely shut down. ÌÌWhen mounting several safety switches, observe the stipulated minimum distance to avoid mutual interference. Installation options min.
Operating Instructions Safety System CES-AP-C.2-AH Electrical connection Warning! In case of an error, loss of the safety function through incorrect connection. ÌÌTo ensure safety, both safety outputs (OA and OB) must always be evaluated. ÌÌThe monitoring output OUT must not be used as a safety output. ÌÌLay the connection cables with protection to prevent the risk of short circuits. Caution! Risk of damage to equipment or malfunctions as a result of incorrect connection.
Operating Instructions Safety System CES-AP-C.2-AH Important: If the device does not appear to function when operating voltage is applied (e.g. green STATE LED does not flash), the safety switch must be returned unopened to the manufacturer. Notes for operation with safe control systems Important: Devices with start button and feedback loop are not suitable for connection to safe control systems.
Operating Instructions Safety System CES-AP-C.2-AH Safety in case of faults ÌÌThe operating voltage UB is reverse polarity protected. ÌÌThe contacts OA/OB are short circuit proof. ÌÌA short circuit between OA and OB is detected by the switch. ÌÌA short circuit in the cable can be excluded by laying the cable with protection. Fuse protection for power supply The power supply must be provided with fuse protection depending on the current required for the outputs. The following rules apply: Max.

Operating Instructions Safety System CES-AP-C.2-AH Connection Connect the device as shown in Figure 3. The OUT output can be connected to a control system as a monitoring output. Important: The subsystem CES-AP complies with PL e in accordance with EN 13849-1. To integrate the subsystem in a category 3 or 4 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 CES system.
Operating Instructions Safety System CES-AP-C.2-AH Warning! In case of an error, loss of the safety function through incorrect connection. ÌÌTo ensure safety, both safety outputs (OA and OB) must always be evaluated. Single-channel use of the safety outputs leads to a loss of the category in accordance with EN ISO 13849-1.

Operating Instructions Safety System CES-AP-C.2-AH Functional check After installation and any fault, the safety function must be fully checked. Proceed as follows: Warning! Danger of fatal injury as a result of faults in installation and functional check. ÌÌBefore carrying out the functional check, make sure that there are no persons in the danger area. ÌÌObserve the valid accident prevention regulations. 1. Switch on operating voltage. ÌÌThe STATE LED then flashes at regular intervals. 2.
