Remedy
Check whether the filter of the
controller is not clogged up.
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 the Drive Unit 1 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 of the
Drive Unit 1 is not clogged up.
Replace the fan.
Check whether the filter of the
Drive Unit 1 is not clogged up.
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 alone, replace the power
supply.
Stop the Drive Unit 2 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 of the
Drive Unit 2 is not clogged up.
Replace the fan.
Check whether the filter of the
Drive Unit 2 is not clogged up.
