Figure 5-22, Tfmr Overtemp Fault

• Tfmr Overtemp - This fault message is displayed when the TCO
(Temperature Cut-Out) opens and causes the inverter to shutdown 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.
5.3.3.2 Remote Fault Message – The remote control may not be functioning
correctly and can also display a fault condition. Refer to the following fault
message to help troubleshoot the remote.

Figure 5-23, Fatal Error $ Fault

• Fatal Error $ - This fault message indicates that the remote's internal
data addressing was unrecognizable; similar to a computer lock-up.
Remedy: Reset the remote by disconnecting the remote commu-
nications cable from the inverter for 5 seconds and then reconnect
(see figure 2-2). If the fault continues after resetting the remote,
the remote requires service at an authorized service facility.
Info: The bottom line may not display correct information while the
Fatal Error $ fault condition is displayed; ignore any remote display
information during a Fatal Error $ fault.

• No Inverter Comm - This fault message indicates that the remote is no
longer receiving any communication data via the Magnum Network.

tions cable from the inverter for 5 seconds and then reconnect (see
figure 2-2). If the fault continues, check/replace the remote cable.
