Voltage dips in the LTMR auxillary power

[cpmibrahim]

We are experiencing shutdown of motors for momentary fluctuations in bus voltage.

Since the auxillary power to the LTMR is derived from main bus ,the relay is shutting down and causing to drop the contactor instantaneously.

In order to bring the motor back ,is it possible to enable restart function?

Will the restart function initiate after  restoration of power to the relay?
