To do that, it is necessary to be in 2 lines mode and to select "Cos Phi" measure ("Space" key). For correct each phase,
it is essential to visualize phase that must be corrected (key "1" for phase "1", key "2" for phase "2").
The function start is realized by "+" or "-" keyboard keys.
At this moment, a message indicates operating mode:
WIRING L1 1/1
Wiring message, corrected phase, wiring type
-0.51
Example of incorrect "Cos Phi" value
1/1 associates L1 with I1
The "+" key allows to modify wiring by specify current (I1 or I2) associated to voltage (L1 or L2).
The "-" key allows to reverse current direction if there is phase opposition, negative Cos Phi value.
When Cos Phi value becomes coherent according to installation, we obtain the next transmission:
WIRING L1 -X/Y
Wiring message, corrected phase, wiring type
0.90
Example of correct "Cos Phi" value
"-" reverses current, "X/Y" associates LX with IY
At this moment, you just have to validate the selected wiring by "Enter" key.
This one is stored and remain active even after a power off.
The procedure is the same for phase 1 and 2.
If the message "WIRING NO CONFORMITY" displays, It must take account only after 2 measured phases correction.
Whenever, if this message displays after complete correction of network, it does mean that a current or a voltage has
been used twice and that chosen wiring is incorrect. It is so necessary to modify wiring by simply changing reference
phase voltage (wired-up in L3-N).
In this unbalanced three-phase without neutral operating mode, it exists for each phase 4 different wiring types. So, in
few seconds and with a tiny intervention on voltage connection, device adapt itself completely to network.
Possible wiring:
Phase L1
voltage 1 with current 1
voltage 1 with current 2
voltage 2 with current 1
voltage 2 with current 2
Phase L2
voltage 1 with current 1
voltage 1 with current 2
voltage 2 with current 1
voltage 2 with current 2
3) Unbalanced three-phase with neutral:
3.1) Operating mode:
In this operating mode, device uses the three voltages and the three currents (L1, L2, L3 and I1, I2, I3 inputs, see dia-
grams of connection). It measures voltage, current and frequency, calculates powers, cos phi, energies for each of the
three phases and determinates finals results of the network (3L).
The device allows to adapt itself to a bad identification of U/I couple of each phase. For instance, by default, device as-
sociates L1 input voltage with I1 input current, and the same for each phase. The wiring function allows to choose cur-
rent/voltage association, that's to say that L1, L2 and L3 will be able to be associated with I1, I2 or I3 in the desire order.
Whenever, a verification will be realized to inform user of a double use of a current, wiring no conformity.
3.2) Method:
The function is realized by the way of RS232 link. It's by a "Cos Phi" value visualization on phases 1, 2 and 3 that user
will be able to determinate if wiring is correct or if it must be modify.
To do that, it is necessary to be in 2 lines mode and to select "Cos Phi" measure ("Space" key). For correct each phase,
it is essential to visualize phase that must be corrected (key "1" for phase "1", key "2" for phase "2", key "3" for phase
"3").
The function start is realized by "+" or "-" keyboard keys.
At this moment, a message indicates the functioning mode:
WIRING L1 1/1
Wiring message, corrected phase, wiring type
-0.51
Example of incorrect "Cos Phi" value
1/1 associates L1 with I1
