RE300 magnetic safety switch
RE300 magnetic safety sensors can be connected directly to the inputs of the
UE410-MU/UE410-GU/UE410-XU as well as UE410-8DI units. Up to eight RE300 can be
connected in series.
The necessary test signals for the RE300 switch are only generated in program 2 on the
UE410-MU/UE410-XU and in switch position 5 on the UE410-8DI. They comply with the
requirements for an application up to PL e according to EN ISO 13
849-1.
An RE300 can only be connected to the local cut-off path on I3 and I4 on the UE410-GU in
program 4 or 5. The necessary test signals (X1/X2) for the magnetic safety switch RE300
meet the requirements for applications up to PL e as per EN ISO 13
849-1.
Pay attention to the safety notes for the RE300 switch.
•
If RE300 sensors are cascaded, these have to be tested/activated regularly (for
example opening and closing of the protective doors connected to the sensors).
•
Cascading of several RE300 sensors is limited by the line resistance (refer to the
operating instructions of the RE300 for further information).
•
If RE300 sensors (N/C / N/O contacts) are connected, the unused input pairs have to
be connected to simulate a logical “1” input correspondingly at the UE410-8DI. The odd-
numbered inputs/test outputs have to be jumpered respectively (for example I1-X1), the
even-numbered inputs/test outputs are not interconnected (for example I2-X2).
