Programmable parameters

Level 1
Password = 1000
1.1 Customised display page
It is possible to set a customised display page where to select which magnitudes should
appear in the three display lines.
If the user sets a customised page, this will become the standard display when the
device is switched on
(as an alternative to the display giving the line voltages)
The magnitudes which can be selected for the customised page are given in the tables
on page 7
1.2 Connection
The instrument can be used for 3 or 4-wire single-phase or three-phase line.
The connections that can be selected are:
Symbol Line Load n°external CT Diagram
1N1E Single-phase -
3-2E 3 three-phase 3 wires Unbalanced
3-3E 3 three-phase 3 wires Unbalanced
3N3E 3 three-phase 4 wires Unbalanced
1.3 Average power and current integration time
Selectable integration time: 5, 8, 10, 15, 20, 30, 60minutes
The selected time is valid for both the current and the average power
1.4 Hour-meter counting start
Select the magnitude which starts the hour-meter counting: voltage or power
Voltage: counting starts with phase voltage > 20V
Power: total active power, programmable value 0.5 ... 50%Pn
1.5 RTU/TCP ModBus RS485 communication
Depending on the model, the instrument may not have communication or may have
RS485 ModBus RTU/TCP communication
No. of address: 1...255
Parity bit: none – even – odd
Waiting time before the answer: 3...100ms
Transmission speed: 4800 – 9600 – 19200 bit/s
1.6 Energy pulses
Associable Measurement: active or reactive energy
Pulse weight: 1imp/10Wh(varh) – 100Wh(varh) – 1kWh(kvarh) - 10kWh(kvarh) -
100kWh(kvarh) – 1MWh(Mvarh) - 10MWh(Mvarh)
Pulse duration: 50 – 100 – 200 – 300ms
