1212E FAULTS
When the controller detects a fault, the controller operates in a manner that is safe in the presence
of that fault. Depending on the severity of the fault, the controller's response can range from
reducing current to shutting down the vehicle.
Some faults are set by multiple conditions. The controller uses fault types to distinguish these
conditions. All faults have a fault type of 1; faults with multiple causes have additional fault types.
Curtis programming devices indicate the fault type.
The emergency messages transmitted when faults occur include the fault type. See Emergency
Message Format.
The following table describes the controller's faults.

cutback is 0 for 64ms
with the main relay on.
1 The undervoltage cutback
is less than 100% with
the main relay on.
1 The capacitor voltage is
10V above the allowed
maximum voltage.
2 The keyswitch voltage
is 4V above the allowed
maximum voltage.
1 The battery voltage is
greater than the user

temperature is greater
than or equal to the
temperature cutback point
for 48ms.
