York YK Centrifugal Chiller

[Koluib]

After long shutdown when we try to start Chiller following Error is displaying and Chiller not Starting."MOTOR CONTROLLER LOSS OF CURRENT"
Anybody have idea why this Error is coming and how to reset it.Thanks.

“MOTOR CONTROLLER – LOSS OF
CURRENT”
The Compressor Motor current decreased to 10% Full
Load Amps (FLA) for 25 continuous seconds while the
chiller was running. This could be caused by the starter
de-energizing during run or a defect in the motor current
feedback circuitry to the Control Center. The chiller
will automatically restart at the completion of “System
Coastdown”.

You're getting a start signal and no current feedback telling the controls that it's running.
