NOTICE
To avoid equipment damage, remove power before
switching modes from signal to power or power to sig-
nal.
•
When the pump control switch (J, F
set in signal mode, the motor/pump runs when volt-
age is applied to the signal and power connectors.

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 10). 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.

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).
