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 CTM-LBI-BR 6.6. Guard locking on version CTM-LBI (guard locking actuated by spring force and released by power-ON) Activating guard locking: close guard; no voltage at control input IMP. Releasing guard locking: apply voltage to control input IMP. The spring-operated guard locking functions in accordance with the closed-circuit current principle.
Operating Instructions Transponder-Coded Safety Switch CTM-LBI-BR 7. Manual release Important! Ì All release functions latch when the device is electrically isolated. Ì Guard locking remains released when the release function is reset. Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test should be performed after release. More information on this topic can be found in the standard EN ISO 14119:2013, section 5.7.5.1.
Operating Instructions Transponder-Coded Safety Switch CTM-LBI-BR 8. Mounting CAUTION Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. Ì Observe EN ISO 14119:2013, section 7, for information about reducing the possibilities for bypassing an interlocking device. NOTICE Risk of damage to equipment and malfunctions as a result of incorrect installation. Ì Safety switches and actuators must not be used as an end stop.
Operating Instructions Transponder-Coded Safety Switch CTM-LBI-BR 9. Electrical connection The following connection options are available: Ì Separate operation Ì Series connection with Y-distributors Ì Series connection, e.g. with wiring in the control cabinet. WARNING In the event of a fault, loss of the safety function due to incorrect connection. Ì To ensure safety, both safety outputs must always be evaluated. Ì Monitoring outputs must not be used as safety outputs.
Operating Instructions Transponder-Coded Safety Switch CTM-LBI-BR 9.1. Notes about Important! Ì For use and operation as per the requirements 1), a power supply with the feature “for use in Class 2 circuits” must be used. Alternative solutions must comply with the following requirements: Electrically isolated power supply unit in combination with fuse as per UL248. This fuse should be designed for max. 3.3 A and should be integrated into the 30 V DC voltage section.
Operating Instructions Transponder-Coded Safety Switch CTM-LBI-BR 9.4. Requirements for connecting cables CAUTION Risk of damage to equipment or malfunctions as a result of incorrect connecting cables. Ì Use connection components and connecting cables from EUCHNER. Ì On the use of other connection components, the requirements in the following table apply. EUCHNER provides no warranty for safe function in case of failure to comply with these requirements.
Operating Instructions Transponder-Coded Safety Switch CTM-LBI-BR 9.5.
