Clear Fault (cont.)
• Cycle control power to the SMC Dialog Plus controller.
Notes: (1) An overload fault cannot be cleared in this way for
firmware releases prior to the following:
- Standard Option 1.07L
- Soft Stop Option 1A07L
- Pump Control Option 1B05L
(2) A communication fault (F21) cannot be cleared in this
way for firmware releases prior to 1.04C.
Important: An overload fault cannot be reset until the Motor Thermal
Usage, parameter 11, value is below 75%. See page 1-7
for further details.
Fault Buffer
The SMC Dialog Plus controller stores in memory the five most
recent faults. Display the fault buffer by selecting the Faults group
and scrolling through the fault buffer parameters. The information is
stored as fault codes. To determine what faults have occurred, use the
fault code cross-reference below.
Fault Codes
Table 9.A provides a complete cross-reference of the available fault
codes and corresponding fault descriptions.

Fault Auxiliary Contact
The auxiliary contact is located at terminals 29 and 30. This contact
can be programmed as either Normal or Fault. Note that the state that
this contact takes upon power-up (normally open or normally closed)
can be programmed. These parameters can be found in either Basic
Setup, Advanced Setup, or the Linear List groups when modifying
parameters in the Program mode.
