7.
Remove the shunt from the power supply output terminals.
3.8.5
OVP Check
Refer to Section 5.3 for
explanation of the OVP function prior to performing the procedure below.
1.
Turn the front panel AC power switch to On position and turn on the output by pressing OUT
pushbutton.
2.
Using the VOLT encoder, adjust the output voltage to approx. 10% of the unit vol
tage ra
t
ing.
3.
Momentarily press the OVP/UVL button so that the CURRENT display shows “OUP”. The
VOLTAGE display will show the last setting of the OVP level.
4.
Rotate the VOLT encoder CCW to adjust the OVP setting to 50% of the unit voltage rating.
5.
Wait a few
seconds until the VOLT display returns to show the output voltage.
6.
Adjust the output voltage toward its maximum and check that the output voltage cannot be i
n-
creased more than the OVP

1.05 setting.
7.
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.
1.
Press the OVP/UVL button TWICE so that the CURRENT display shows “UUL”. The VOLTAGE
di
s
play will show the last settin
g of the UVL level.
2.
Rotate the VOLT encoder to adjust the UVL level to approx. 10% of the unit voltage rating.
3.
Wait a few seconds until the VOLT display returns to show the output voltage.
4.
Adjust the output voltage toward its minimum and check that the out
put voltage cannot be d
e-
creased below the UVL x 1.05 setting.
5.
Adjust the UVL limit to the minimum by repeating Sep 1 and rotating the VOLT encoder CCW.
3.8.7
Foldback Check
Refer to Section 5.5 for explanation of the FOLD function prior to performing the
procedure below.
1.
Ensure that the output voltage is set to approx. 10% of the unit rating.
2.
Adjust the CURRENT encoder to set the current limit to approx. 10% of the unit rating.
3.
Momentarily press the FOLD button. Ensure that the FOLD LED illuminates. The ou
tput voltage
remains u
n
changed.
4.
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.
5.
Press the FOLD button again to cancel the protection. The output
voltage remains zero.
6.
Press OUT button. Ensure that the output voltage returns to its last setting.
7.
Turn the output off by pressing the OUT button. Ensure that the VOLT display shows “OFF”.
3.8.8
Address Setting
1.
Press and hold the REM/LOC button for approx. 3 se
c. The VOLT display will show the commun
i-
cation port a
d
dress.
2.
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 (RS
-
232 and RS
-
485 only)
1.
Press and hold the REM/LOC button for approx. 3 sec. The
CURRENT display will show the co
m-
munication port Baud Rate.
2.
Using The CURRENT adjust encoder, check that the Baud Rate can be set to 1200, 2400, 4800,
9600 and 19200.
Shorting the output may expose the user to hazar
d
ous
voltages. Observe proper safety procedures.
