6.3 Test
For a standard-compliant design of the protecti on, the primary machine control must perform a test prior
to each dangerous movement or during the non-dangerous phase/movement of the machine. Upon appli-
cati on of the test signal, the output terminal of the switching unit must open. This change in switching state
must be evaluated by the primary machine control . If the test result is correct, the machine control then
initi ates the movement or the next work step. Otherwise, the control must output an error message and
the power-driven work equipment (e.g. motor) must receive a switch-off signal from the machine control.
The available test signal can be selected with the DIP slide switch.
