2.3) Value acquisition:
Example:
LOW SCALE
4 mA
Two possibilities:
- The validation without modification by pushing on
"Enter"
/
"EXE"
,
- The keyboard value modification (simultaneous display), then the validation by
"Enter"
/
"EXE"
.
Note concerning the value acquisition:
- It is possible, when a mistake is made during a value acquisition, before validating it, to go back by pressing the "DEL"
key (only on PSION), which re-displays the message without taking notice of the wrong value.
- In configuration mode, if there's no action during 2 minutes, device goes back in operating mode without taking notice
of the modifications made before.- In configuration mode, if you want to shift to measure mode without taking notice of
modifications made before, you just have to press "ESC" (PC) or "SHIFT + DEL" (PSION) key.
In configuration, if channels/phases sum is chosen, device calculates:
- channels mean for voltages, currents and frequency.
- channels sum for powers and energies.
- network result for cos phi (power factor)
3) Language:
Languages possibilities are French or English.
4) Network:
The possibilities of wiring on network are:
- in AC:
- one-phase,
- balanced three-phase without neutral,
- balanced three-phase with neutral,
- unbalanced three-phase without neutral,
- unbalanced three-phase with neutral.
- in DC:
- 1 channel,
- 2 channels,
- 3 channels.
It is also necessary to configure ratio transformer if inputs are not directly wired on network:
- PT ratio, potential transformer,
- CT ratio, current transformer.
Ex:
Intensity transformer with 100 A primary and 5 A secondary.
Transformer ratio setting = primary / secondary = 20.
5) Energy:
This menu gets the possibility to:
- validate the access to the energies reset with push-buttons on device's front side (display option),
- reset all the energies.
Warning:
All the energies are definitely reset.
6) Relays 1 and 2:
Each of the two relays has the same possibilities of configuration.
The relay can be use in two modes : alarm or energy meter.
6.1) Alarm:
The relays configuration in alarm is composed of 2 rubrics:
- measures parameters:
measured value:
- star voltage or interlinked voltage (according to network type),
- current,
- frequency,
- cos phi,
- active, reactive, apparent power
- active consumed or generated energy,
- reactive inductive or capacitive energy.
