d) Rotate the VOLT encoder CCW to adjust the OVP setting to 50% of the unit voltage
rating.
e) Wait a few seconds until the VOLT display returns to show the Output Voltage.
f) Adjust the Output Voltage toward its maximum and check that the Output Voltage
cannot be increased more than the OVP setting.
g) Adjust OVP limit to the maximum by repeating Step 3 and rotating the VOLT
encoder C.W.
3.8.6 UVL Check
Refer to Section 5.4 for explanation of the UVL function prior to performing the
procedure below.
a) Press the OVP/UVL button TWICE so that the CURRENT display shows “UUL”. The
VOLTAGE display will show the last setting of the UVL level.
b) Rotate the VOLT encoder to adjust the UVL level to approx. 10% of the unit voltage
rating.
c) Wait a few seconds until the VOLT display returns to show the output voltage.
d) Adjust the output voltage toward its minimum and check that the output voltage
cannot be decreased below the UVL setting.
e) Adjust the UVL limit to the minimum by repeating Step 1 and rotating the VOLT
encoder CCW
3.8.7 Foldback Check
WARNING
Shorting the output may expose the user to hazardous voltages.
Observe proper safety procedures.
Refer to Section 5.5 for explanation of the FOLD function prior to performing the
procedure below.
a) Ensure that the Output Voltage is set to approx. 10% of the unit rating.
b) Adjust the CURRENT encoder to set the Output Current setting to approx. 10% of
the unit rating.
c) Momentarily press the FOLD button. Ensure that the FOLD LED illuminates. The
Output Voltage remains unchanged.
d) Short the output terminals momentarily (approx. 0.5 sec.). Ensure that the Output
Voltage falls to zero, the VOLT display shows “Fb” and the ALARM LED blinks.
e) Press the FOLD button again to cancel the protection. The Output Voltage remains
zero.
f) Press the OUT button. Ensure that the Output Voltage returns to its last setting.
g) Turn the output off by pressing the OUT button. Ensure that the VOLT display shows
“OFF”.
3.8.8 Address Setting
a) Press and hold the REM/LOC button for approx. 3 sec. The VOLT display will show
the communication port address.
b) Using the VOLT adjust encoder, check that the address can be set within the range
of 0 to 30.
3.8.9 Baud Rate Setting (RS232 and RS485 only)
a) Press and hold the REM/LOC button for approx. 3 sec. The CURRENT display will
show the communication port Baud Rate.
b) Using The CURRENT adjust encoder, check that the Baud Rate can be set to 1200,
2400, 4800, 9600 and 19200.
