Starting Delay
Table 4.38 Antibackspin Setting
In certain pump applications, fluid flowing
backward through the pump may spin the pump
motor for a short time after the motor is stopped.
It is dangerous to attempt to start the motor
during this time. To prevent motor starts during
the backspin period, enter a time in minutes in the
Antibackspin Starting Delay setting. If the relay
trips or the motor is stopped, the relay will
generate a trip signal and maintain it for at least
this amount of time. The relay will not issue a
start during the antibackspin period.
The Emergency Restart function overrides the
Antibackspin function allowing the motor to be
placed back in service in an emergency.
