Event
1 At least one input is switched OFF. The GuardStopRequestStatus bit is set to 1.
2 Second input is switched OFF within 1 second of event 1. This event must always occur
within 1 second to prevent a GuardStopInputFault condition. For more information see
QSHT 5700 Inverter Fault Troubleshooting on page
3 First input is switched ON.
4 Second input is switched ON within 1 second of event 3.
5 Both inputs are in the ON state simultaneously within 1 second. As a result, Guard-
StopInputFault is not posted.
6 The GuardStopRequestStatus bit sets back to 0 if event 4 occurs within a 100 ms inter-
val after event 3. If event 4 is outside of the 100 ms interval, but within the 1 second
interval after event 3, then the GuardStopRequestStatus bit sets back to 0 after the 1
second interval following event 3 (not immediately following event 4).
