Remedy
If normal voltage is not generated by a
24V power supply alone, replace the
power supply.
Stop the controller as soon as possible
and check whether the ambient
temperature of the controller is not
high.
Check whether the filter is not clogged
up.
Check whether the filter is not clogged
up. If the warning is not cleared after
the controller is rebooted, replace the
fan.
Check whether the filter is not clogged
up. If the warning is not cleared after
the controller is rebooted, replace the
fan.
Stop the controller as soon as possible
and check whether the ambient
temperature of the controller is not
high.
Check whether the filter is not clogged
up.
If normal voltage is not generated by
3.3V of Drive Unit 1 power supply
alone, replace the power supply.
If normal voltage is not generated by
5V of Drive Unit 1 power supply alone,
replace the power supply.
If normal voltage is not generated by
24V of Drive Unit 1 power supply
alone, replace the power supply.
Stop Drive Unit 1 as soon as possible
and check whether the ambient
temperature of Drive Unit 1 is not high.
Check whether the filter is not clogged
up.
Check whether the filter of Drive Unit 1
is not clogged up. If the warning is
not cleared after the controller is
rebooted, replace the fan.
Check whether the filter of Drive Unit 1
is not clogged up. If the warning is
not cleared after the controller is
rebooted, replace the fan.
If normal voltage is not generated by
3.3V of Drive Unit 2 power supply
alone, replace the power supply.
If normal voltage is not generated by
5V of Drive Unit 2 power supply alone,
replace the power supply.
If normal voltage is not generated by
24V of Drive Unit 2 power supply
