WARNING!!!
The digital fault label programming must match with the external
control wiring to the controller. Failure to do so may cause severe
equipment damage.
9.5.2. ACTION
This setting allows a fault circuit to be programmed as either an
alarm
or a
shutdown
.
Note:
All activated alarm and shutdown faults will energize the “common fail”
circuit and sound the alarm horn.
9.5.3. 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 no unlatch until a reset
command clears it.
Note:
This programming prompt only appears if alarm faults
are programmed. Shutdown faults are automatically set as latching.
9.5.4. POLARITY
This setting allows the digital fault circuit to be set for
Open to Fail
or
Close to
Fail
sensing contacts.
9.5.5. 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).
9.5.6. 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.
9.5.7. IDLE CONTROL DIGITAL INPUT PROGRAMMING
When a digital input is programmed as Idle function, the following settings must
be programmed to ensure correct operation.
