Pump Control Operation
• When the pump control switch (J, F
IG
. 9 page 11) is
set in signal mode, the motor/pump runs when volt-
age is applied to the signal and power connectors.
• When the pump control switch (J, F
IG
. 9 page 11) is
set in power mode, the motor/pump runs when volt-
age is applied to the power connectors. The signal
connectors do not require voltage.
Current Control and Flow Motor
Control Settings
Current and Flow Control Adjustment
1. Remove screws (a), cover (b) and gasket (c) to
access the control board (F
IG
. 10).
2. Current and Flow control are adjusted on the Motor
Control Board using the Current Control Potentiom-
eter Knob (G) and the Flow Control Potentiometer
Knob (H) (page 11). The Current Control knob (G)
governs pump speed, which in turn governs flow.
The Current setting has precedence over the Flow
Rate setting. You may be limited in achievable Flow
Rate by the Current setting.
Turn knob clockwise to increase setting value.
• Turn knob counter-clockwise to decrease set-
ting value.
NOTE: Values are based on lab test conditions at ambi-
ent temperature 72°F (22°C) with an input voltage of
24V. Actual results may very and should be verified in
the application.
3. Replace gasket (c) and cover (b) and screws (a),
being careful not to pinch any wires. Tighten bolts
securely. Torque bolts to 17-19 ft.-lbs (23-26 N.m).
