Table 5-3. Errors Related to Protection Function (2/2)
State Cause Description
Abnormal
output voltage
Output voltage or voltage applied
to the output terminal is an
overvoltage.
The overload LED (OVLD) is on.
Output cannot be turned on when the output voltage is
abnormal.
Output is turned off immediately if an abnormal output
voltage is detected when output is turned on. The LED in
the output on/off switch (OUTPUT) blinks at this time.
The LED blink can be reset by pressing the output on/off
switch.
A transition is made to disable mode, and the overload LED
(OVLD) blinks if the abnormal output voltage state lasts
for 60 seconds. This product cannot be operated in disable
mode, so turn off the power.
If the overload LED (OVLD) is on even when the input
signal, bias, and output are off, this product may have
failed.
Internal power
supply
abnormality Voltage of amplifier DC power
supply (internal power supply) is
lower than specification.
Operations other than power-off are disabled while the
LEDs are blinking.
Turn off the power, and then turn it on again.
If the LEDs keep blinking, this product may have failed.
