Auxiliarx output
The Qx_PP, Qx_PN and Qx- outputs are subjected to a plausibility test in all operating states. In
switched on state the correct function of all outputs is tested with a cyclic test pulse. For this
purpose the output is switched to the corresponding inverse value for a test period TT <500µs
(typically 200 µs) i.e. one P-output is switched instantaneously to 0 VDC potential, while one M-
output is switched to 24 VDC potential.
The relay outputs are monitored for plausibility during each switching cycle. The relay outputs
must be switched cyclically and thus tested to maintain the safety function. The switching/test
cycle is determined in dependence on the application.
