Features

The WellZone™ digital controller provides pressure control for single phase 2-wire submersible well pump applications. It uses a 0-150 PSI pressure transducer to monitor the discharge pressure and turns the pump ON and OFF according to the Start and Stop setpoints. The LCD display is visible through the clear cover of the enclosure to allow for quick view of the system pressure, run status, hours run and pump cycles. The rotary button provides the user with a simple navigation method through the menu and program settings. It features built in pump protection including rapid cycling and dry run. It is preprogrammed to run the pump as the pressure drops below 40 PSI and stop as the pressure rises above 60 PSI. High & Low pressure settings are available with an auxiliary alarm relay.

Mounting the Control Panel

1. Drill and fasten top of the enclosure using appropriate anchor.
2. Drill and fasten bottom of the enclosure using appropriate anchors.

Wiring the Control Panel

CAUTION!
Disconnect all power to the control panel before wiring.
Ensure that the incoming supply power voltage is the same as the rating of the pump motor being installed. Ensure that the rated Amps of the motor does not exceed the rating of the control panel.

1. Connect the following wires to the proper terminal positions:
   • Incoming power to the circuit breaker
   • Motor/Pump power to Motor
   • Pressure transducer
   See wiring label on inside the control panel for details.

2. Verify correct operation of control panel after the installation is complete.

3. Maximum motor cable lengths.

¹Cable length is measured from the motor to the main panelboard (Service Entrance) 75C Insulation – AWG Copper Wire only. Do not use aluminum conductors.
Use with 2-wire motor only with internal thermal protection.
²Typical S.F.A. (Service Factor Amps). Check motor nameplate for actual data.

Operation Guide

Notes :
A. If there is no operation for 20 sec, the display will return to the main screen.
B. The service function is used for alerting the user when it is time to change a filter or to serivce the equipment after the accumulated run time is reached.
The icon will flash on main screen when the timer is done (Filter at 0%).
Push and hold ESC button 4 seconds to reset the filter or service time.

Parameter| Description| Default| Range Min| Range Max| Unit| Function
---|---|---|---|---|---|---
START| Start Pressure| 40.0| 1.0| 140.0| PSI| The pump will RUN when the pressure drops below the “START” pressure value and continue to RUN until the pressure rises above the “STOP” value.
Set START<STOP. The “STOP” value should be at least 10 PSI over the “START” value.
STOP| Stop Pressure| 60.0| 10.0| 150.0| PSI| The pump will RUN when the pressure drops below the “START” pressure value and continue to RUN until the pressure rises above the “STOP” value.
HIGH| High Pressure| 70.0| 0.0| 150.0| PSI| High Pressure alarm. The pump will stop if the pressure rises above this value.
LOW| Low Pressure| 20.0| 0.0| 150.0| PSI| Low Pressure alarm. If the pressure drops below this value, the “LOW TMR” timer will start. The pump will stop when the timer is done and a “LOW PRESS” alarm will be displayed.
LOW TMR| Low Pressure Timer| 30| 0| 3599s(59m:59s)| Seconds| Low pressure timer. This delay timer needs to be long enough to allow the pump to pressurize the system on start up. It can be used to detect a broken discharge pipe or significant leak. Value is in Seconds (s).
OVERLOAD| Motor Overload| 12.0| 4.0| 14.0| Amps| Set to the motor S.F.A. (Service Factor Amps) value as listed on the motor nameplate. The pump will stop if it is pulling excessive amps and the “OVERLOAD” alarm will be displayed. The controller will reset the fault automatically after a cooling period. The controller will reset this fault 4 times automatically before requiring a manual reset.
DRY RUN| Dry Run Amps| 0.0| 0.0| 14.0| Amps| Pump DRY RUN protection. Set this value lower than the normal pump operating amps. 30% lower than the motor Service Factor Amps is common. Adjust up or down as this function is tested. Example: Motor SFA = 10.0A. Set the Dry Run Amps = 7.0A. Set to “0.0” to disable this function (Default).
DRY TMR| Dry Run Timer| 30| 0| 3599s(59m:59s)| Seconds| Time delay before stopping the pump on “DRY RUN” as the amps are lower than the “DRY RUN” amps value. Timer value is in seconds (s).
RECHARGE| Recharge Timer| 20| 0| 3599m(59h:59m)| Minutes| Automatic reset timer after a “DRY RUN” trip, allowing for enough time for the well to recharge. Timer value is in minutes (m).
STRT / MIN| Starts Per Minute| 2| 1| 10| Cycles| Rapid cycle protection. Enter the maximum allowable pump starts per minute. If the number of starts is exceeded, the display will show “RPD CYCL” and a manual reset is required for the pump to start again.
NO AMPS| No Amps Detect| ON| ON| OFF| NA| No amps detection function informs the user of thermal switch trip internal to the motor. Allow the motor to cool and it will start again automatically. This detection function is disabled when set to “OFF”.
FILTER| Filter Life Timer| 200| 1| 9999| Hours| Set the estimated pump run time between filter replacements. The time is set in hours (h) and corresponds to pump running hours. will flash on the screen when this timer is done.

Fault Information

Pressure below the Low Pressure set point for longer
than the Low Pressure Timer.| Check for leaks, broken pipes.
Check the pump and motor.
| STOPS
PUMP| Auto reset  when PSI is back to normal| HIGH PRESSURE ALARM
Pressure greater than the High Pressure set point.| Check pump, piping and pressure tank.
| STOPS
PUMP| Hold ESC for 4 sec to reset or cycle power| PUMP DRY RUN ALARM
Pump DRY RUN protection.  Set this value lower than the normal pump operating amps.  30% lower than the motor Service Factor Amps is common.   Example:
Motor SFA = 10.0A.  Set the Dry Run Amps = 7.0A.
Set to “0.0” to disable this function (Default).| If the pump is tripping on DRY RUN but there is water in the well, decrease this setting. If the pump is NOT tripping on DRY RUN, then increase this value.
| STOPS
PUMP| Hold ESC for 4 sec to
reset or cycle power| PUMP RAPID CYCLING ALARM
This is the maximum allowable pump starts per minute.
If the number of cycles per minute is exceeded, the pump will not start and the RDP CYCL alarm will be displayed.| Check the pressure tank for damage or incorrect pre-charge pressure. These  commonly result in the pump rapid cycling.  Correct or replace pressure tank.  Increase the number starts per minute for
systems with small pressure tanks. Contact the pump/motor manufacturer for the max allowable starts/minutes.
| STOPS
PUMP| Auto reset / Manual reset| MOTOR OVERLOAD TRIP
Class10 overload protection, calculated based on the
motor S.F.A. load.
The overload will automatically reset after a cooling period. It must be manually reset after four consecutive times trips.| Check the pump for clogging or locked rotor condition.
| STOPS
PUMP| Auto reset| WATER DETECTION SWITCH ALARM
Digital input from the optional floor sensor or float switch.  If the input of water sensor is ON for more than 5 sec, shut down the pump and display “WATER SW”.
This alarm will auto reset when the switch opens.| Check the water sensor or float switch.
Correct the cause of water leakage or water supply prior to resetting the fault.
| STOPS
PUMP| Auto reset| PRESSURE TRANSDUCER OPEN CONNECTION
Active when the 4-20mA signal input value is < 3.0mA| Check the transducer cable connection to the pressure sensor.  Make sure it is connected properly and hand tightened.
Check the transducer cable for damage. Replace cable if damaged.
Check the transducer cable connections to the controller.  Make sure there is a  good connection.
| STOPS
PUMP| Auto reset| PRESSURE TRANSDUCER SHORT CIRCUIT
Active when the 4-20mA signal input value is > 21mA| Same as above.  In addition, check the pressure transducer.
Remove it and inspect for damage. Replace if is it damaged.
| WAITING
FOR AUTO
RESET| Hold ESC for 4 sec if you want to cancel the timer and re-start the pump immediately| WELL IS RECHARGING – PLEASE STAND BY
This is the waiting time after the pump as tripped on
“Dry Run” fault, before performing an automatic reset.| Wait for the recharge timer to complete.
Increase or decrease this timer value as needed to match the recovery time of your well.
| NO
CHANGE| Hold ESC for 4 sec if you want to cancel the timer and re-start the pump immediately| NO AMPS DETECTED
No amps are detected which implies that the thermal switch internal to the motor has tripped or that the pump is not connected.
When the “NO AMPS” function is enabled, it will ignore the Low Pressure and Dry Run conditions and maintained the RUN command to the pump unitl the motor has cooled down and restarts automatically.| If it is a motor thermal trip, then allow the motor to cool and it will start again automatically.
Investigate the cause of the motor nternal trip.
If the motor is not connected, check the motor wiring.  The NO AMPS function can be disabled when set to “OFF”.

Auto Reset – resets when the fault clears
Manual Reset – press and hold ESC button over 4 seconds in main screen.
