Replace the battery for the CPU board
immediately. Keep the controller ON as long
as possible until the battery is replaced.
If normal voltage is not generated by 5V power
supply alone, replace the power supply.
If normal voltage is not generated by 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.
