MAINTENANCE

(MAINTENANCE)

The MAINTENANCE menu is to be used only by qualified and trained personnel, who knows the problems of the inverter
control and specific DGBOX characteristics.
The menu permits two types of jobs:

a)

Inspection and routing maintenance jobs

b)

Configuration of the critical parameters for inverter operation and reset operations

List of alarms during functioning

It allows displaying the chronology and type of alarms which have tripped over time, and analysing the operating
data at the time of each alarm. An example of the analysis of the parameters during an alarm is shown below.
