Commissioning
The multi-functional power monitor is made operational by switching on
the power supply. The following appears sequentially on the display:
1. Segment tests: all the segments of the displays and all the LEDs are
lit for 2 s.
2. Version of the software: e.g. ES210 1.04
3. The 3 line voltages at switching on.
Loss of the power supply
All the values configured remain during a loss of the power
supply. On reconnecting the power supply, the last mode selected is
displayed.
Electrical connections
The electrical connections are identical for the ES210 and
ES220).
