RVS-DX, Digital Soft Starter Instruction Manual—04/01/04
7-6
Final torque during soft-stopping a pump motor
1. While decelerating, the check valve may close
before Deceleration Time has elapsed, thus,
allowing current to flow through stator winding
causing unnecessary heat. Select Final Torque
sensitivity to 1, and stop the pump, confirm that
current stopped flowing through the motor
shortly after the check valve closed.
2. If current still flows more than 3-5 seconds
after check valve closure, increase Final Torque
up to 10 if necessary, to stop current flow earlier.
