1.8 Run hour meter count start
Select the quantity which starts the run hour meter count: voltage or power
Voltage: phase voltage > 10V
Power: 3-phase active rated power
Programmable value: 0...50%Pn
Pn = 3-phase active rated power = 3-phase rated voltage Un x rated current In x√3
Un: 400V
In: 1A or 5A
= 400V x5A x √3= 3464W or 400V x1A x√3= 692,8W

1.9 RS485 communication
(where provided)
According to the models, this meter can be without communication or equipped with
RS485 ModBus RTU/TCP
Address number: 1...255
Parity bit: none – even – odd
Waiting time before answer: 3...100ms
Transmission speed: 4800 – 9600 – 19200 – 38400 bit/s
ModBus message word format
1 Just for 32-bit quantities
1.10 Pulse output
(max. 27V 50ma)
Quantity that can be coupled: active or reactive energy
Pulse weight: 1pulse/10Wh(varh) – 100Wh(varh) – 1kWh(kvarh) - 10kWh(kvarh) -
100kWh(kvarh) – 1MWh(Mvarh) - 10MWh(Mvarh)
Width of the pulse: 50 – 100 – 200 – 300 – 400 – 500ms
1.11 Harmonic Analysis
Display mode: up to the 9 th harmonic or up to the 25
Password = 2001

2.1 External VT or CT ratio
Vt = External primary/secondary VT ratio
Ct = External primary/secondary CT ratio
External CT ratio (Ct): 1...9999
External VT ratio (Vt): 1,00...10,00
For voltage direct connection (without external VT) load Vt=1,00
By modifying the CT and/or VT

Phase sequence diagnostic
In the software of the device we have added a specific functionality to detect and correct
many problems concerning voltage and / or current connection.
This function can be activated through password and allows to display and modify the
connection sequence provided that the following conditions are respected:
1) The neutral wire (in a 4-wire network) is connected to the right terminal
ber 1)
2) No crossings between cables connected to CT's
nals 1 and 3 - are connected some way both to CT1 and CT2)
3) The power factor is between 1 and 0,5 - Inductive load - for each phase.
