potential. DO NOT touch the Application Setting Switches while the power is on.
Hazardous
voltage
The controller has 6 possible Application Settings. These settings are used to adjust the Minimum Speed of the
motor and the Ramp Setting, or acceleration and deceleration ramp. This allows the controller to fit a wide range
of applications.
Before adjusting the Application Switches, turn the circuit breaker and disconnect switch to the off position. Wait
5 minutes. Remove the controller access cover. On the inside of the access cover is the Application Switch Setting
Table. See Diagram 6 for details. This table shows the switch setting needed for the desired system response. See
Diagram 3 for details.
Select a Minimum Speed of 10 Hz if the pressure at the pump's suction is within 20 PSI of the desired pressure
setting. Select a Minimum Speed of 30Hz if the pressure at the pump's suction is more than 20 PSI below the
desired pressure setting, if pumping from a tank or if drawing a suction lift.
Changing the Ramp Setting changes how fast the controller can change the speed of the motor. A Slow Ramp
Setting allows the controller to work better in applications where the average demand for water is low (less than
3GPM or about 1 faucet). A Fast Ramp Setting allows the controller to work better in applications where the
demand for water is high because the motor is allowed to change speed faster.
Note
The Application Switches are preset at the factory to "0000" or Minimum Speed = 30 Hz, Ramp
Setting = Fast.

Motor Rotation Direction

If the pressure or flow seems low, check motor rotation direction. Turn the circuit breaker and disconnect switch
to the off position, and wait 5 minutes. Switch any two leads on the controller output (T1, T2, or T3). Turn the
circuit breaker and disconnect switch to the on position. Observe pressure and flow. If pressure or flow still
seems low check plumbing.
Note
It is possible for the pump to maintain constant pressure with a low flow or a high positive 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 controller is always powered. A Solid Green Status Code indicates that the pump is in standby mode (pump
not running) or that the line input voltage is low.
Danger
Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch

and circuit breaker and wait 5 minutes before servicing.
Hazardous
voltage
A Blinking Green Status Code indicates that the pump is running. A Blinking or Solid Red Light indicates a problem
with the controller. Refer to the access cover side panel or Diagram 6 for Status Codes. See Section 9 for more
details.
