5.2 When Fault Symptoms Are Observed
When a fault symptom shown below is observed, perform the corresponding action required. Contact NF
Corporation or its representative if the symptom cannot be corrected.
Table 5-4. When Fault Symptoms Are Observed (1/2)
Symptom Possible cause Action required
This product does not
operate when the
power switch is turned
on.
This product is not connected to a
live power. Securely connect the power cord to a live power
outlet and to the inlet of this product.
There is no output.
Signal not connected.
Connect the signal generator and correctly select an
input signal selection switch.
Input selection not made.
The output on/off switch
(OUTPUT) is not set to ON.
Set the output on/off switch to ON.
The output on/off switch
(OUTPUT) cannot be set to ON.
Output cannot be turned off when the overload LED
(OVLD) is turned on.
Release the condition for turning on the overload
LED referring to the required action shown in
"
Table 5-2 Errors Related to Protection
Function (1/2) " for a case where the overload
LED (OVLD) is turned on.
When the overload LED (OVLD) is blinking, all
switch operations are disabled. Turn off the power
switch.
Release the condition for blinking the overload LED
then turn on the power switch referring to the
required action shown in "
Table 5-2 Errors
Related to Protection Function (1/2) " for a
case where the overload LED (OVLD) blinks.
The output voltage
waveform is distorted
when the overload
LED (OVLD) is off.
AC peak current protection is
working.
Overload occurs. If you drive a capacitive load with
square wave, the output current flows more when
the output voltage waveform rises or falls than when
it is steady.
Lower the load within the maximum output current
(AC peak value) referring to "
4.1 Maximum
Output Current and Operation Range " or
slow the rise time or fall time of the input signal or
lower the input signal (output voltage).
Overload occurs when
the input signal is a
square wave, even if
with no load.
Since the input signal quickly
rises and falls, the current that is
charged to the stray capacitance in
this product reaches the peak
current protection level.
Lower the input signal (output voltage) or use a
signal generator, such as the NF WF1947, that
controls the rise and fall of waveforms to decrease
the rise and fall time.
