Thanks all, you have confirmed my suspicions.
The motor is a 230/460 50 hp 3 phase 9 lead motor connected to a part winding starter wired for 230 volts. it is connected to a pump for a water slide.
I suspect two things, 11 seconds timing is way too much and attendants stopping and restarting...
Called to replace a 230 volt 3 phase delta wound motor.
Motor had caught fire, no one could tell me when it had caught fire, (at start or while running) everyone knew nothing...
Sent the motor off for rewind.
While waiting for motor to be returned, tested the starter.
The start starter closed...
