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:

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
(rated power)
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
Programming
The programming is divided on two levels protected by two different numerical passwords
and takes place by means of the
front keypad with 4 keys
