Check the Phase Monitor lights.
If the green light is lit the power phasing is correct and
you may proceed with voltage sensitivity level adjust-
ment.
If the red light is lit; either the sensitivity level is too low or
the phasing is incorrect to provide clockwise rotation of
the motor.
Rotate the sensitivity adjustment a full rotation counterclockwise (low
voltage).
If the red light turns off and the green light turns on the phasing
is correct for clockwise rotation of the motor.
If the red light does not turn off the phasing is incorrect.
Reverse two (2) of the power leads to the line connection terminals to
change the motor rotation direction.
Verify that the green light is now lit.
Sensitivity Adjustment
Adjust the sensitivity by rotating the adjustment clockwise towards the ‘high’
setting until the green light turns off and the red light turns on.
Rotate the adjustment counterclockwise 1/8 of a turn or until the green light
turns on.
If the line voltage is subject to frequent small voltage drops, it may be
necessary to lower the sensitivity by an additional 1/8 turn to prevent
random trips.
If any of the leads in the Phase Monitor circuit wires have been
inadvertently disconnected, the rotation direction must be checked to
ensure proper clockwise rotation.
Remove the inspection cover on the Motor to Pump Adapter to provide visual
inspection of the shaft coupling.
Set the Flow Direction control to neutral, the Volume control to zero and pull
the Stop button to the up position.
