1.1 Customized display page
Possibility to load a customized display page on which you can choose which quantities
the three display lines must show.
If the user loads a customized page, this will become the standard display when the
meter is switched on
(as alternative the one showing the line voltages).
The selectable displays for the customized page are mentioned in the tables page 7.
1.2 Connection
The meter can be used for single phase or three phase 3- and 4-wire network.
The selectable connections are:
1.3 Current delay time and average power
Selectable delay time: 5, 8, 10, 15, 20, 30, 60 minutes
The selected time is valid both for the current and the average power
1.4 Display lighting
The 4 selectable levels (0 – 35 – 70 – 100%) show the display lighting percentage
1.5 Run hour meter count start
Select the quantity which starts the run hour meter count: voltage or power.
Voltage: count start with phase voltage > 20V
Power: total active power, programmable value 0,5…50%Pn (rated power)
1.6 RS485 communication (where provided)
According to the models, this meter can be without communication or equipped with
RS485 ModBus RTU/TCP or RS485 BACNET communication
1.6a RS485 ModBus RTU/TCP communication
Address number: 1...255
