6-2 Single-phase, Three-wire Operation
OT01-PCR-LA/2
6.1
Basic Operations
This section describes the operation method for the PCR-LA power supplies, which
differs from the method for operating a PCR-LA power supply singly. Unless other-
wise speci
fi
ed, operation of a PCR-LA power supply refers to the U-phase unit.
For information not provided here, see the PCR-LA AC Power Supply Operation
Manual.
Display during single-phase, three-wire Operation
■
Display common to each phase
The three-phase symbol
and the letter “U” or “V” appear at the left of the volt-
age display area. In this case, the letters indicate that the PCR-LA power supplies
have been set to their respective phases. The voltage display value set at factory
shipment is the phase voltage.
If the letters U-V are displayed at the left of the voltage display area, the PCR-LA
power supplies display the respective line voltages.
■
V-phase unit display
The control panels display only the phase (V) indication, voltage and current indica-
tions, and the load level meter.
■
U-phase unit display
When the three-phase symbol
and all of the letters “U” and “V” appear at the
left of the current display area during power display, the total power of the single-
phase three-wire is indicated.
If the three-phase symbol
and the letter “U” or “V” appear at the left of the cur-
rent display area during a self-test, the U-phase power supply displays the self-test
results for each indicated phase.
6.2
Switching of Output Voltage Display
There are the phase voltage display and line voltage display modes. In the factory
shipment status, the PCR-LA power supplies enter the phase voltage display mode
when the SYSTEM POWER switch is turned ON.
Procedure for switching between phase voltage and line voltage
displays
1.
Press the ESC key to select the Home Position.
2.
Press the PHASE (SHIFT, 2) key.
This changes the phase voltage display mode to the line voltage display mode.
3.
To display the phase voltage, press the PHASE (SHIFT, 2) key again.
