4. Alarm handling and log list
4.1 Alarm handling
When an alarm occurs, the unit will automatically go to the alarm list for display of the alarm. This function
can be disabled or enabled. For further explanation, please see the Designer’s Reference Handbook.
If you do not want to read the alarms, use the BACK push-button to exit the alarm list.
If you want to enter the alarm list later, use the INFO push-button to jump directly to the alarm list reading.
The alarm list contains both acknowledged and unacknowledged alarms, provided that they are still active
(that is the alarm condition is still present). Once an alarm is acknowledged and the condition has disap-
peared, the alarm will no longer be displayed in the alarm list.
This means that if there are no alarms, the alarm list will be empty.
This display example indicates an unacknowledged alarm. The display can only show one alarm at a time.
Therefore, all other alarms are hidden.
Use the and push-buttons to scroll in the display and see the other alarms.
Place the cursor (underscore) under ACK and then press SELECT to acknowledge an alarm.
Place the cursor under the selection FIRST or LAST and then press SELECT to jump to the first (oldest) or
the last (most recent) alarm.
4.2 Log list
An event is for example closing of breaker and starting of engine. An alarm is for example over-current or
high cooling water temperature. A battery test is for example test OK or test failed.
The logging of data is divided into three different groups:
● Event log containing 150 loggings
● Alarm log containing 30 loggings
● Battery test log containing 52 loggings
