opens in case of failure. At the same time, the respective error is indicated in plain text in
the display:

- display and relay
missing reactive power
OVER COMPENSATED
- display and relay
OVER CURRENT
- display and relay
MEASURING VOLTAGE ???

Additionally, several messages for different operation states are generated. An individual
adjustment resp. masking of single messages is possible in EXPERT-MODE 2.
During masking, the display of message, the eventual output via alarm relay and possible

Section 15: OSCI-MODE
Section 16: MAINTENANCE AND WARRANTY
No maintenance is required when operation conditions are obeyed. Nevertheless a
functional check of the controller together with the rotational check of the compensation
system is recommended.
The typical life expectancy of the internal Li-battery is min. 8...10 years. It is firmly
connected to the circuit board and should only be exchanged by the manufacturer.
In the event of any interventions in the controller during the warranty period, all warranty
claims lapse.
