Page 5: Correct Use
Operating Instructions Transponder-Coded Safety Switch CTS-C2-BP/BR-FLX 2. Correct use Safety switches series CTS-C2-BP/BR-FLX are interlocking devices with guard locking solenoid (type 4) for process protection without safe guard lock monitoring. The device complies with the requirements according to EN 60947-5-3. The device can be configured with the aid of a function actuator. Depending on the function actuator taught-in, guard lock monitoring for process protection is permanently active or available as an additional option and the evaluation of the actuator code has a high or low coding level. - Page 6 EN 60204-1 Ì The safety switch is allowed to be operated only in conjunction with the intended EUCHNER actuators and the related con- nection components from EUCHNER. If different actuators or other connection components are used, EUCHNER provides no warranty for safe function.
