The T4000 Multi transponder safety switch consists of three components:
•
S
ensor
T
he sensor is mounted on the fixed part of the guard and is connected to the eval‐
uat
ion unit.
•
A
c
tuator (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 a
t le
ast IP54. Depending on the evaluation unit variant (see "Product variants",
page 11), 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.
