DKM-411 User Manual Rev_01 Firmware V-1.0
K46D03-EN - 52 -
The device is able to generate fault conditions on adjustable limits of measured parameters.
Fault cases are considered under two categories, namely alarm and warnings:
1- ALARMS: These are the most important fault conditions.
2- WARNINGS: Less severe fault conditions.
Occurring fault conditions will cause the related function to become active. These conditions are displayed in
the ALARM LIST screen. Conditions may also be assigned to relay outputs, activating external circuitry.
Alarms operate in a first occurring basis:
-If an alarm is present, following alarms 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.
In case of fault condition, if the button is pressed, the
alarm output will be deactivated; however the existing alarms
will persist.
If a fault condition occurs, the display will automatically
switch to the ALARM LIST page.
Existing alarms may be canceled by long-pressing the
button.
