Test and start

The BSR23 is a safety relay for output expansion of other safety devices. The internal relays will
follow the safety input channels directly and individually. The safety relay needs to be
monitored by the master unit controlling it. This is done via X1/X2 which need to be included in
serial connection with the test/reset circuit of the master unit.

Arc suppression for inductive loads is recommended to get a longer
lifetime for the relay contacts.
