Function mode 2 – 1oo1 Test
(T0, T2, T4, T6 static off )
Signal evaluation of up to 2 independent single-channel
switches/sensors (NO or NC) per channel pair. In this function
mode, T0, T2, T4, T6 are not connected to any voltage.

Tab. 1/15: Function mode 2 – 1oo1 Test
Function mode 2 can be used as a test modewhen you con­
nect sensors for function mode 1
This way, a safety controller used alternately in function
modes 1 and 2 can generate user-specific test signals and
evaluate if a zero crossing has taken place.
Software-generated test signals only work with the following
connection blocks:
– CPX-M-AB-4-M12X2-5POL-T
– CPX-AB-8-KL-4POL.
Note
During the test period, safety requirements cannot be eval­
uated with the safety controller.
Function mode 2 can alternatively be used for resetting
sensors with self-monitoring electronic outputs.
