Motor FLA Requirements
The front of the SMC controller contains a dial that is used for setting the
actual FLA of the motor. The label is designed to accommodate motors
connected in the line or Delta mode. To determine the proper setting, look at
the motor’s nameplate and set the dial accordingly. The dial setting can be
modified depending on the service factor of the motor.

The controller incorporates, as standard, electronic overload
protection. This motor overload protection is accomplished
electronically by using internal current transformers on each of the
three phases.

In manual reset mode, the fault can only be reset by pushing the ‘Push to Reset’ button
on the front of the controller. In auto reset mode, the unit automatically resets when
the unit determines the motor has cooled to 75% of its thermal capacity.

Switch #14 Description
Normal
OFF
The operation defines the operation of the auxiliary contacts. Normal mode means
that the contact changes state immediately when a start/run command is given.
Up-to-Speed mode means that the contact changes state only when the controller
is in bypass. Aux#2, when added, operates opposite of this programming.
