Timing diagram
The pump pressure function is activated when the measured pressure reaches the
pressure limit. The pump goes to backspin mode after the delay time is passed and
thereafter stops.

Pump torque protection
The pump torque protection function protects the pump from overload or under load
condition and triggers warnings and faults. This function is activated when the
measured rod torque exceeds the defined torque limit and when the measured speed
exceeds the defined speed limit. The rod torque protection is based on the
measurement of rod torque value. This function also enables pump protection with
motor current. The user can select this option in parameter 77.01 Rod torq limit
display.
•If Torque is selected, there is rod torque protection.
•If Current is selected, there is motor current protection.
