TLS-ZR GD2 / TLS-ZL GD2 Solenoid Interlock Switch The TLS-ZR GD2 and TLS-ZL GD2 are additions to the existing TLS GD2 range of guard locking switches. The TLSZR GD2 is a power-to-release and the TLS-ZL GD2 is a power-to-lock unit. They may be used as part of a guard locking system to achieve performance Level "e" to EN/ISO 13849‐1. They are certified by the TÜV as meeting EN/ISO 13849-1. In mechanical configuration they are identical to the existing TLS-GD2 range with the exception that they include an additional RFID door target which is mounted close coupled with the supplied fully-flexible actuator. These switches have built in microprocessor technology and have two channel OSSD solid-state outputs. Locking/unlocking is achieved using a logic level signal input. The RFID door target is uniquely coded and provides the internal microprocessor with additional door position information. Therefore, in the event of a broken or missing actuator key the microprocessor will shut down the OSSD safety outputs. This extra functionality enables performance level "e" to EN/ISO 13849-1 to be reached as there is no reliance on fault exclusion for a broken or missing actuator key. The TLS-GD2 range are positive mode, tongue operated, guard locking interlock switches that can lock a machine guard closed until power is isolated and ensure that it remains isolated while the guard is open. The TLS-ZR GD2 and TLS-ZL GD2 head has two entry slots and it can be rotated to provide three actuator entry points. A blanking plug is provided to seal the unused slot. The TLS-ZR GD2 is a power-to-release switch, the guard may only be opened when a logic signal is applied to the switch after which the internal microprocessor will enable the internal solenoid, which releases the lock mechanism. The TLS-ZL GD2 is a power-to-lock switch, the guard will be locked when a logic signal is...
