1.1 Resets
Possibility to reset the performed counts
1.1a Partial Active energy
1.1b Current Max Demand
1.1c Power Max Demand
1.1d Hour Meter (working minutes and hours)
Run hour function, working minutes and hour counting, is operating when the device
detects L1 phase.
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 Power demand
Combined power: active, reactive, apparent
1.4 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
1.5 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
1.5a RS485 ModBus RTU/TCP communication
Address number 1...255
Transmission speed: 4,8 – 9,6 – 19,2 kbit/s
Parity bit: none – even – odd
Waiting time before answer: 3...100ms
It is usually advisable to load 003 (3ms). If, in the connection to other interfaces the
communication is lacking, try to increase the value.
