Control Terminal Designations
As shown in Figure 2.10, the SMC-Flex controller contains 24 control
terminals on the front of the controller.

Do not connect any additional loads to these terminals. These “parasitic” loads may cause problems with operation,
which may result in false starting and stopping.
;
Aux. Contact #1 is always programmed for Up-to-Speed to control the bypass contactor in MV applications.
➌
Aux. Contact #2 is always programmed for “Normal” indication in MV applications.
➍
RC snubbers are required on inductive loads connected to auxiliary.
Note: The OFF state leakage current for a solid-state device connected to an SMC-Flex input must be less than 6 mA.
