10.4.3. ALARM
LATCH
If an alarm fault was programmed, it may be selected as a ”latching” alarm or
“non-latching”. When “latching” is selected, it will not un-latch until a reset
command clears it.
Note:
This programming prompt only appears if alarm faults
are programmed. Shutdown faults are automatically set as latching.
10.4.4. BYPASS ON START DELAY
This allows the alarm or shutdown circuit to be disabled until after the bypass
timer has expired. Fault circuits that are not delayed will be enabled at all times
(i.e. engine running or stopped).
10.4.5. TRANSIENT DELAY TIMES
This allows the selected fault circuit to be inhibited from being activated until the
specified time delay period has expired. Delay times from 0.0 to 999.9 seconds
are available by entering the time required.
10.5. DIGITAL FAULT PROGRAMMING MENU
To program the controller’s digital fault circuits, refer to the following descriptions.
