External K time monitoring: If selected, enables the setting of the time window within which the
external feedback signal is to be monitored (according to following output conditions).
OUTPUT

With high level (TRUE) OUTPUT, the FBK signal must be at low level (FALSE) within the set time.
Otherwise, OUTPUT is set to low level (FALSE) and the error is indicated on the master MOSAIC M1
by the flashing CLEAR LED corresponding to the OSSD in error.
Enable Error Out: If selected, enables the ERROR OUT output. This output is set to high level
(TRUE) when an external FBK error is detected.
The Error Out signal is reset in case of one of the following events:
1. Switching on and switching off of system.
2. Activation of the RESET MOSAIC M1 operator.
Example of OSSD with correct Feedback signal:
In this case ERROR OUT=FALSE
OSSD feedback unconnected: If selected, the feedback must not be connected. If not selected the
feedback must be connected directly to 24V or through the series of NC contacts of K1/K2.
