Figure 5-30, Tfmr Overtemp Fault

• Tfmr Overtemp – This fault message is displayed when the TCO

(Temperature Cut-Out) opens and causes the inverter to shut down to

protect the internal power transformer from damage. When the TCO has

cooled down, the inverter will automatically restart and resume operation.

Remedy: If the fault occurs while inverting, reduce the load on the

inverter. If it occurs while charging, turn down the charge rate. If

this fault occurs often, ensure the inverter is in a cool location, has

adequate ventilation, and the internal cooling fans are operational.

Unknown Fault XX appears on the

LCD. The FAULT (red) LED is on. The

PWR (green), CHG (green), and INV

• Unknown Fault – This fault message displays when the inverter/

charger has sent a fault code that cannot be determined by the remote.

Remedy: Call the Technical Support department at Magnum Energy

(425-353-8833) to assist you.

Remedy: The AC pass-thru relay is most likely stuck. A relay usu-

ally sticks because of damage to the contacts from trying to handle

currents greater than they are rated. This is usually caused by not

protecting the relay from handling high continuous currents, or by

switching high current inductive loads. The internal relay contacts are

rated to handle 30 amps AC continuously and should be protected

with a breaker sized no larger than 30 amps. If you are connected

to an AC source (grid or generator) and running large inductive

loads (i.e., pumps, motors, etc.,) on the inverter output, turn those

particular loads off prior to removing the AC input source. This fault

requires an inverter or power reset (Sections 6.2 & 6.3) to clear.
