Operating Instructions Transponder-Coded Safety Switch CTP/CTA-L1/2-BR 2. Correct use Safety switches series CTP‑L1/2-… and CTA-L1/2-… are interlocking devices with guard locking solenoid (type 4). The device meets the requirements according to EN IEC 60947‑5‑3. Devices with unicode evaluation possess a high coding level, devices with multicode evaluation possess a low coding level.
Operating Instructions Transponder-Coded Safety Switch CTP/CTA-L1/2-BR 3. Description of the safety function Devices from this series feature the following safety functions: Monitoring of guard locking and the position of the guard (interlocking device with guard locking according to EN ISO 14119) Ì Safety function (see chapter 6.5. Switching states on page 11): - The safety outputs are switched off when guard locking is released (monitoring of the locking element).
Operating Instructions Transponder-Coded Safety Switch CTP/CTA-L1/2-BR 4. Exclusion of liability and warranty In case of failure to comply with the conditions for correct use stated above, or if the safety regulations are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void. 5. General safety precautions Safety switches fulfill personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Operating Instructions Transponder-Coded Safety Switch CTP/CTA-L1/2-BR 6. Function The device permits the locking of movable guards. The system consists of the following components: coded actuator (transponder) and switch. Transponder-coded actuator Whether the device learns the complete actuator code (unicode) or not (multicode) depends on the respective version.
Operating Instructions Transponder-Coded Safety Switch CTP/CTA-L1/2-BR 6.2.7. Communication connection C A monitoring output with the suffix C has the additional function of providing a communication connection to a BR/IO-Link Gateway. The switch delivers cyclical and acyclical data. You will find an overview of the communication data in chapter 11. Using communication data on page 32. If no BR/IO-Link Gateway is connected, this output behaves like a monitoring output. 6.3.
Operating Instructions Transponder-Coded Safety Switch CTP/CTA-L1/2-BR 6.4.3. Guard locking on version CTP/CTA-L1 and control via IO-Link communication (guard locking actuated by spring force and released by power-ON) Activating guard locking: close guard; no auxiliary voltage at the solenoid and set bit CL. Releasing guard locking: apply auxiliary voltage to the solenoid and clear bit CL. The spring-operated guard locking functions in accordance with the closed-circuit current principle.
