FAILURE 95: WATCH DOG
If the watch dog has been activated, message 95 is logged in the Error log register. If this occurs often, ask
the help of a technician.
FAILURE 300-353: MITSUBISHI INVERTER ALARM MESSAGE
Always make sure you have the correct inverter parameter settings in the inverter, especially when you have
replaced an inverter. If you are not sure go to the Configuration menu and select „Inverter Menu...", set the
correct machine type and supply voltage and load the parameters from the wash computer to the inverter
once more. If the correct parameters are not in the inverter all kind of inverter alarms may occur. See also
inverter manual (available on request) for more info.

Short circuit in brake transistor circuit. Power off
immediately! Replace the inverter.
Output overcurrent to ground.
1) Check the motorcable and motor for ground faults.
2) Disconnect the motorcable and try again. If you still
have the error, replace the inverter.
External thermal relay (TRM module, see electrical
scheme) for motor protection tripped. TRM module was
only used on certain machines with MCB controller and
A500 inverter.
See detailed explanation below
Memory was overwritten too many times. Replace inverter.
See detailed explanation below
The max number of retries after fault reached.
The actual inverter error code that causes the problem and
which should be solved, is stored just before Err 316 in the
error log.
Communication error of built in CPU. Replace inverter
Internal fault, If the fault is persistent, replace the inverter
Internal fault, If the fault is persistent, replace the inverter
Power failure between 15 and 100ms. Check for bad
contacts in the power circuit. Repair the power supply.
Supply voltage too low. Check jumper P/+-P1.
Phase open detected on inverter output. Check for bad
contacts or defect (open) motor windings.
Problem with the option in slot 1 or option contact fault
Problem with the option in slot 2 or option contact fault
Problem with the option in slot 3 or option contact fault
