Overview
Fault Timeout controls the delay before fault actions are performed.
Restriction
Fault Timeout is applied only to the following alarms (listed by Status Alarm Code): A003, A004, A005,
A008, A016, A017, A033. For all other alarms, fault actions are performed as soon as the alarm is
detected.
Procedure
Set Fault Timeout as desired.
The default value is 0 seconds. The range is 0 to 60 seconds.
If you set Fault Timeout to 0, fault actions are performed as soon as the alarm condition is
detected.
The fault timeout period begins when the transmitter detects an alarm condition. During
the fault timeout period, the transmitter continues to report its last valid measurements.
If the fault timeout period expires while the alarm is still active, the fault actions are
performed. If the alarm condition clears before the fault timeout expires, no fault actions
are performed.
