Troubleshooting
A COATS® Service Technician may ask for informa-
tion to help diagnose service concerns (please contact
COATS directly at 1-800-688-9240 for the Certified
Service Partner nearest you). Conveying this informa-
tion to your service technician prior to servicing can help
to expedite service to your equipment. Although much
of the diagnostic information aids your COATS Service
Technician, several remedies for balancer misfunctions
are available to the operator.
Error Messages - One of the following error mes-
sages, shown in the display windows, may appear

Inverter Error - An inverter error occurs when one of
several fault conditions is detected by the inverter; such
as, low line voltage, motor over temperature, motor
overload or motor drive over temperature. The balancer
will not respond to inputs until the fault condition is
corrected. The balancer will clear this error as soon as
possible and indicate that with the following message:
Inverter Fault Cleared. Press Any Icon
Overload Protection - The balancer’s motor is over-
load protected per UL requirements. After 4 to 5 min-
utes the machine automatically resets itself; activating
the fan motor. If this happens, notify your Certified
Service Partner immediately.
Important: Allow the fan to cool the motor for at least
30 minutes before using the balancer so the overload
protection is not tripped again.
