Actuator (transponder)
The T4000 Multi transponder safety switch consists of three components:
•
Sensor
The sensor is mounted on the fixed part of the guard and is connected to the eval‐
uation unit.
•
Actuator (transponder)
The actuator is mounted on the movable part of the guard.
Each actuator has a unique electronic code.
•
Evaluation unit
The evaluation unit must be installed in a control cabinet with an enclosure rating
of at least IP54. Depending on the evaluation unit variant (
), up to two or up to four sensors can be connected to the evaluation
unit.
Operating principle
The T4000 Multi transponder safety switch monitors movable physical guards:
■
Operation of the machine in automatic mode is possible only if the guards are
closed.
■
A stop command is triggered if the guard is opened while the machine is running.
The T4000 Multi transponder safety switch is uniquely coded: An actuator must be
taught in at the connected sensors during commissioning.
