Cycle Sensor: Installation (CS3PH1-500HP)
(Lock out feature: To lock or unlock adjustment settings, hold up and down buttons at the same time.)
Step 1: Mount the pump control in the desired location and wire the unit according to the
appropriate wiring diagram on the following pages. Make sure all local, state, and national
electrical codes are followed.
Apply power to the unit as per diagram.
Step 2: To View the Current Transformer Ratio, press and hold the "Man. Res./CT Ratio" button. Momentarily
press the "Up" button to view the present programmed CT ratio. Follow the chart below to determine the CT (current
transformer) ratio, the number of wire passes through the center of the CT, and the number to program for the CT
|Motor FLA Range||CT Ratio||Number of|
|1 to 7.5 Amps||50:5||10||"5"|
|7.5 to 25 Amps||50:5||2||"25"|
|25 to 75 Amps||50:5||1||"50"|
|75 to 250 Amps||250:5||1||"250"|
|250 to 500 Amps||500:5||1||"500"|
To Change the CT Ratio Setting, continue to press and hold the "Manual Reset"button while pressing either the "Up"
or "Down" until the display matches the appropriate CT ratio setting. Since the update time on this setting is slow,
you will need to hold the "Up" or "Down" button for several seconds to change to the next number.
Step 3: To Set the Current Adjustment Setting, insure that all water valves are closed, so that the pump will be
pressurizing the tank when operating. Press and hold the "Manual Reset" button and observe the number that is being
displayed by the pump control. This number represents the amp-draw of the motor. You will need to multiply this
number by .95 to determine the set point.
Release the "Manual Reset" button and press and hold the "Current Adjust" button. The display will show the present
Current Adjust setting. Modify this number to match the above calculated set point by pressing either the "Up" or
"Down" button. Release all of the buttons when this step is completed.
Note- If the pressure switch shuts the pump down before completing this step, you will need to depressurize the
system by opening a valve, and repeat the process.
Step 4: To View the Dry Run Restart Delay Setting, push and hold the "Restart Delay"button. The display will show
the number in minutes the pump will be off before automatically restarting from a dry run condition. To change this
number, press either the "Up" or "Down" button until the display matches the desired restart delay setting. Release
all buttons. "000" is manual reset only.
Step 5: To View the Rapid Cycle Setting, push and hold the "Rapid Cycle" button. The display will show the number
of seconds required between pump start-ups without locking out on a rapid cycle condition. To change this number,
press either the "Up" or "Down" button until the display matches the desired rapid cycle setting. Release all buttons.
Step 6: Observe the operation of the system, insuring that the pump control is set correctly. If the pump control
is too sensitive, reduce the "Current Adjust" setting by repeating Step 2. If the well will pump dry, insure that the
pump control will shut the pump down when it breaks suction for 10 seconds. If the pump control does not shut down
when the pump breaks suction, increase the under current setting by holding the "Current Adjust" button and pushing up
button. Repeat this step until set.
