INFORMATION
A "discrepancy / stability time error" is reported if there is either a temporary or
permanent discrepancy (a difference) between the two input signals,
or the input signals are not stable (refer to Chapter 2.2.3).
This error is also reported if the safeguard has not been closed correctly or
if a temporary single-channel switch-off has occurred.
INFORMATION
Discrepancy errors can also be detected for electronic safety switchgear
(= switched off cross-fault detection) if there is a short circuit to +24 VDC
or 0 VDC at the safety inputs X1/X2 or the pulse outputs Y1/Y2.
Check device connection cables!
INFORMATION
This fault can only be acknowledged after the safety guard has been opened
one time without fault.
For certain types of interlocks, it may be necessary to switch off the operating
voltage of the interlock or of the SFB-PN one time in order to acknowledge the
fault.
