notice
 
The overall machine safety depends on the professional mounting and installation of the safety monitoring module and the signal transmitter, as well as on the correct and professional electrical connection of the components.
If there it any risk whatsoever, the machine may not be restarted.
 
notice - Wiring example
 
Monitoring the safety edges SE 40 / SE 70 with a safety monitoring unit SE-304C up to PL d and Category 3.
Manual reset function or auto-reset:
The manual reset function is triggered by an edge-sensitive signal (edge switching "0-1-0" within 100 ms up to 2 s) (X2/X3). Alternatively, the auto-reset function can be activated by a connection (A3/X2).
Both re-initialisation and auto-reset must comply with the requirements of EN 1760-2 (diagram A2, A3).
If less than 4 safety edges are connected, the following diagram must be observed.
The wiring diagram is shown for the de-energised condition.
