Bulletin 1560E • DPI Control – Controlled Start only

The control scheme shown in Figure 1.27 allows the MV SMC-Flex to be

controlled using DPI. This special usage of DPI includes provisions for a

"Hand" mode of control as well.

With the Hand-Auto selector switch in the "Auto" position, and closure of

the existing starter main contactor, terminal 18 is energized, allowing a

start command to be executed via DPI. "AUX2" serves as an interlock

with the main contactor (or breaker) in the existing starter.

As with the other control schemes, the SMC-Flex module closes "AUX1",

energizing "B-IV", as the motor approaches rated speed.

Hand control is enabled with the selector switch in the "Hand" position.

Closure of the "Start" relay, from the existing starter, allows the unit to

initiate motor soft starting.
