Wiring Examples
The application examples shown are suggestions. They however do not exempt the user from carefully checking whether the Safety door switch
and its set-up are suitable for the individual application.
The power supply for the safety door switch must provide protection against permanent overvoltage.
To that effect, stabilized PELV supply units must be used. The safety outputs can be directly connected in the safety circuit of the control system.
For applications of PL e / safety category 4 in accordance with ISO 13849-1, the safety outputs of the safety door switch or safety door switch of
the chain must be connected to a safety controller or safety relay unit of the same Safety Category. If the safety door switch is wired to relays or
to non-safety relevant control components, a new risk analysis must be carried out.
If the safety door switch is connected to the safety input of a safety controller, the controller must have a dual-channel monitoring time of at least
100 ms and the accepted test pulse duration of at least 1 ms. Also, the cross-wire-short monitoring function must be disabled. Typically, a switch-
off time of 250 µs is reached with a 30-m connecting cable. The switch-off time of the safety door switch is additionally extended depending on the
cable length and the capacity of the cable used.
D41D series connection example
When connecting multiple safety door switches in series, apply 24 VDC to safety inputs X1 and X2 on the Nth unit, as shown in the figure below.
Connect safety outputs Y1 and Y2 to safety inputs X1 and X2 of the following safety door switch.
Connect safety outputs Y1 and Y2 of the first unit to the safety controller or safety relay unit. Connect the auxiliary output to the PLC, etc.
When connecting a single safety door switch to the safety controller or safety relay unit, apply 24 VDC to safety inputs X1 and X2 in the same
manner as the Nth unit shown below, and then connect safety outputs Y1 and Y2 to the safety controller or safety relay unit.
