. Line to line voltages will appear when the setpoint
S2 SYSTEM SETUP \ CURRENT/VOLTAGE CONFIGURATION \ VT WIRING
is stored as
DELTA
.
Ia/Ib/Ic/In MAX THD:
The maximum total harmonic value for each current input and the
time and date which the maximum value occurred are displayed. The
S1 PQM SETUP \ CLEAR DATA \ CLEAR MAX THD VALUES
setpoint clears this value.
Van/Vbn/Vcn/Vab/Vbc MAX THD:
These messages display the maximum total harmonic
value for each voltage input and the time and date at which the maximum value occurred.
The setpoint
S1 PQM SETUP \ CLEAR DATA \ CLEAR MAX THD VALUES
is used to clear
this value. Phase to neutral voltages will appear when the setpoint
S2 SYSTEM SETUP \ CURRENT/VOLTAGE CONFIGURATION \ VT WIRING
is set to
WYE
.
Line to line voltages will appear when the setpoint
S2 SYSTEM SETUP \ CURRENT/
VOLTAGE CONFIGURATION \ VT WIRING
is set to
DELTA
.

Data Logger
FIGURE 5–19: Actual Values Page 3 – Data Logger
DATA LOG 1:
This message display the current status of the Data Logger 1. The Data
Logger can be set up and run only from EnerVista PQM Setup. See Sections 6.6.4: Data
Logger on page –22 and A.6: Data Logger Implementation on page –15 for a details on the
Data Logger feature.
It is possible to stop the data logger from the PQM front panel using the
S2 SYSTEM SETUP/DATA LOGGER/STOP DATA LOGGER 1
setpoint.
DATA LOG 2:
See DATA LOG 1 description above and replace all references to DATA LOGGER
1 with DATA LOGGER 2.
