n Enabling Suction Pressure Control
The suction pressure control selection is added to parameter Q5-01 Water Level/Suction Pressure Selection. Follow the steps
below for basic suction pressure control setup:
1.
Enable suction control by setting parameter Q5-01 to 1 (Suction Control).
2.
Set suction transducer scaling (Q5-02) in psi, scaling for analog input A1 (20 mA scale).
3.
Set suction pressure setpoint (Q5-03) in psi.
4.
Select iQpump operation when a drop in suction pressure occurs:
Regulate outlet pressure only and go to sleep immediately when suction pressure falls below minimum suction
pressure level (Q5-04). Set suction pressure setpoint (Q5-03) below minimum suction pressure level (Q5-04).
Regulate suction pressure when pressure is below suction pressure setpoint (Q5-03) but above the minimum suction
pressure level (Q5-04). Set suction pressure setpoint (Q5-03) to above the minimum suction pressure level (Q5-04).
5.
Set minimum suction pressure (Q5-04) – Sleep Level for Suction Control.
6.
Set suction pressure wake-up level (Q5-06) – Wake-up level.
7.
Set suction control minimum speed (Q5-08) – Minimum Flow Speed.
