Read the fault code of an electric motor
Where the panel shows the numeric fault code of a metering motor controller, and what each code means.
When a metering motor raises “FAILURE”, its controller also records a numeric code. Read it out and give it to the service support together with the number of the motor.
On the home screen, open the context menu of the faulty motor: hold its tile, or hold “MENU”, step to the motor with “UP” / “DOWN” and press “MENU”.
Select “Information” and press “MENU”. The status screen of the motor opens.
Read the line “Last fault”. The status of the motor reads “Faulty” while any of its alarms is active.
The same code is shown as “Error code” on the Motors screen — see Motors screen and Motor controller diagnostics.
The codes
The panel shows only the number. The descriptions come from the motor controller itself.
Command and parameter errors
The controller refused something the panel asked of it.
