Most of the alarms are of LATCHING type. Even if the alarm condition is removed, the alarms will stay
on and disable the operation of the genset.
The existing alarms may be canceled by pressing one of the operating mode buttons (
LOAD TEST /

) or by pressing the
ALARM MUTE

If the

button is pressed, the alarm relay output will be deactivated; however the
existing alarms will persist and disable the operation of the genset.
Most of the alarms have programmable trip levels. See the programming chapter for settable alarm
limits.
The digital inputs are programmable and may be set to provide a large variety of alarms and warnings.
See the programming chapter for digital input programming.
The alarms may be cancelled either by pressing any of the front panel mode selection buttons or by a
change in external mode force inputs.
