ELMON board 31-30
Safety Relais
6.3 Test
For a standard-compliant design of the protection, 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-
cation 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
initiates 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.

Test
With testing by the control, the ELMON board 31 system satisfies the Cat. 2 require-
ments in accordance with EN ISO 13849-1:2008 "Safety-related parts of control
systems" .
Without testing, the operation or wiring of the ELMON board 31 satisfies no specific
safety requirement.
