Symptom3: No output is generated when the OUTPUT switch
is turned on.
Check Item Cause and Remedy
□
A special load is con-
nected. • The output overvoltage protection function may be
activated. See "2.2 Load".
□
The control cable for
analog remote control is
disconnected. • The output overvoltage protection function has
been activated. Connect the cable correctly by
referring to "4.1 Analog Remote Control".
□
The external voltage is
an overvoltage for ana-
log remote control. • The output overvoltage protection function has
been activated. Connect the cable correctly by
referring to "4.1 Analog Remote Control".
□
The internal tempera-
ture is abnormally high. • The overheat protection function has been acti-
vated. The ambient temperature may exceed the
operating ambient temperature, the inlet or exhaust
port may be blocked, the dust filter may be
clogged, or the fan may have malfunctioned. If
there is no problem in the operating environment
and the alarm is activated, immediately stop the
use of the instrument and request for repairs.
□
Load cable is long
while using remote
sensing function. • The polarity of the remote sensing cable may be
reversed, or the ends may be shorted. The load
cable may also be too thin or too long. Set up the
environment so that the voltage drop in the load
cable is within the conpensation voltage range (0.6
V for a single line). See "3.3.1 Load Cable" and
"3.6 Remote Sensing"
Check Item Cause and Remedy
□
Both "CV" and "CC"
indications are off. • The VOLTAGE and CURRENT is set to 0 V and 0
A, respectively. Both LEDs may not light up
depending on the internal offset adjustment.
This is not a malfunction. Set the VOLTAGE and
CURRENT to the required output using the dial.
□
VOLTAGE or CUR-
RENT is set to 0. • Set the VOLTAGE and CURRENT to the required
output using the dial.
□
The OUTPUT ON indi-
cation is off (OFF is
illuminated). • See "4.1.6 Controlling the Output ON/OFF Using
External Contact".
□
The OUTPUT ON indi-
cation is on. • CV contorl setting or CC control setting in the
CONFIG settings may be “1” (external control).
Set it to “0” (panel control). See "3.2.4 Unit Con-
figuration (CONFIG)"
