4-18 Operation Method
RC04-PCR-LA
• A setting item can be changed in either the OUTPUT ON or
OUTPUT OFF condition. However, the timing of RUN (sim-
ulation start) is as described below.
When T2 = T4 = 0:
Before performing RUN, always
set OUTPUT OFF. (Then, set
OUTPUT ON again and press the
F1 (RUN) key to start a simula-
tion.)
When T2
≠
0 or T4
≠
0: Setting items can be changed while
the OUTPUT ON condition is
maintained, and then RUN can be
performed.
13.Press the F3 (STOP) key. This stops simulation of power
line abnormality.
14.Press the ESC key to exit the power line abnormality simu-
lation function.
This will cancel the key-lock mode in the PCR-LA power supply.
Pressing the ESC key on the PCR-LA power supply also allows
you to exit the power line abnormality simulation function in the
same way.
• Voltage Change Start Polarity (POL)
Switching the voltage change start characteristic (POL)
causes zero crossing (the time at which voltage reaches the
zero level), which is the start point of T1 to be set to a positive
zero crossing or negative zero crossing shown in the
fi
gure
below. This function changes phase by 180 degrees. In this
case, the output voltage (waveform) of L is based on N of the
PCR-LA AC power supply OUTPUT terminal board.
