digital output to operate.
2-

led to turn on steadily,
-
The genset contactor to be released immediately,
-

-
The

digital output to operate.
3-
WARNINGS:
These conditions cause:
-
The
WARNING
led to turn on steadily,
-
The

Alarms operate in a first occurring basis:
-If a shutdown alarm is present, following shutdown alarms, loaddumps and warnings will not be accepted,
-If a loaddump is present, following loaddumps and warnings will not be accepted,
-If a warning is present, following warnings will not be accepted.
Alarms may be of
LATCHING
type following programming.
For latching alarms, even if the alarm condition is removed, the alarms will stay on and disable the operation
of the genset.
Most of the alarms have programmable trip levels. See the programming chapter for adjustable alarm limits.
If the ALARM MUTE button is pressed, the Alarm output will be
deactivated; however the existing alarms will persist and
disable the operation of the genset.
If a fault condition occurs, the display will automatically
switch to the ALARM LIST page.
Existing alarms may be canceled by pressing one of the
operating mode buttons:
