3.
Momentarily press the OVP/UVL button so that the CURRENT displayshows “OUP”. T he
VOLTAGE display will show the last se
t
ting 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 setting.
7.
Adjust OVP limit to th
e maximum by repea
t
ing Step 3 and rotating the VOLT encoder CW.
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 showthe last sett ing 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 i
ts minimum and check that the output voltage cannot be d
e-
creased below the UVL setting.
5.
Adjust the UVL limit to the minimum by repeating Step 1 and rotating the VOLT encoder CCW.
3.8.7
Foldback Check
Refer to Section 5.5 for explanation of the FOLD function pr
ior 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 Output Current setting to approx. 10% of the unit rating.
3.
Momentarily press the FOLD button. Ensure that t
he FOLD LED illuminates. The Output Voltage
r
e
mains unchanged.
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 ALARMLED blinks.
5.
Press the FOLD button again to can
cel the protection. The Output Voltage remains zero.
6.
Press the 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 sec. The VOLT display will show the commun
i-
cation port address.
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 RE
M/LOC button for approx. 3 sec. The CURRENT display will showthe
communication port Baud Rate.
Using The CURRENT adjust encoder, check that the Baud Rate can be set to 1200, 2400, 4800,
9600 and 19200.
WARNING
Shorting the output may expose the user to hazar
d
ous
voltages. Observe proper safety procedures.
