Starting the System
Section 7
(continued)
Setting the Pressure
When power is applied the pump will start and the system pressure will increase to the factory preset pressure
(50 PSI if SP1 is enabled and a 300 PSI sensor is used or 75PSI if SP2 is enabled and a 300 PSI sensor is used).
After the pressure has stabilized, use the increase (INC) or decrease (DEC) pressure adjust pushbuttons to adjust
the pressure setting. Push and Hold the increase or decrease pushbutton until the desired pressure setting is
reached. The new pressure setting will save when the system goes into standby mode (solid green light/pump
off). Pressure set point 1 will be adjusted and stored when the SP2/SP1 switch input is open. Pressure set point 1
is preset to 50 PSI when used with a 300 PSI transducer. Pressure set point 2 will be adjusted and stored when
the SP2/SP1 switch input is closed. Pressure set point 2 is preset to 75 PSI when used with a 300 PSI transducer.
Motor Rotation Direction
If the pressure/flow seems low or the system is indicating Motor Overload error check the motor rotation
direction. Turn the breaker/disconnect switch to the off position and wait 5 minutes. Switch any two leads on the
controller output (T1/U, T2/V or T3/W). Turn the breaker/disconnect switch to the on position. Observe pressure
and flow. If the pressure or flow still seems low check plumbing.
For CentriPro Motors, connecting T1/U to Red, T2/V to Black and T3/W to Yellow will give the correct rotation.
Note
It is possible for the pump to maintain constant pressure with a low flow or a high suction head
even if the pump is rotating backwards. While the pump is running use an amp probe on one of the
output power leads connected to the motor and compare the current draw between the two rotation
directions. The lowest current reading indicates the pump is running in the correct direction.
System Status
The status indicator light displays the status of the controller. A constant green status code indicates that the
pump is in standby mode (pump not running). A blinking green status code indicates that the pump is running.
A constant orange light indicates the input voltage is low. A blinking or constant red light indicates a problem
with the controller or system. Refer to the access cover side panel for a list of status codes. See Section 9 for more
details.
Danger
The status code indicator light is not a voltage indicator! Always turn off disconnect
