Warning
High Voltage Electrocution Hazard
Hazardous voltage can shock, burn, cause serious injury
and or death. To reduce the risk of electrocution and or
electric shock hazards:
•Only qualified technicians should remove the panel
•Replace damaged wiring immediately
•Insure panel is properly grounded and bonded

Important Information
Page 2
•Sense and Dispense™ is designed for use with the following Goldline Controls:
ProLogic ™(Version 3.0 or greater)
Aqua Plus ™(Version 3.0 or greater)
AquaRite Pro ™
•In all cases, verify that proper water flow is passing through the flow cell.
•Remember to recalibrate the pH probe anytime it has been cleaned or replaced.
•Always measure the complete water chemistry using a third party test kit(s)
capable of testing salt, free chlorine, pH, alkalinity, stabilizer, calcium hardness,
and phosphates.

Recommended probe maintenance schedule:
Probe maintenance indicators:
1. Slow response to water chemistry changes.
2. Increased need to calibrate pH.
3. Inconsistent readings.
Maintenance
Page 3
1. Probes must be clean and free of oils, mineral deposits, and contamination in
order to function properly.
2. Probe tips must be kept wet at all times, if left out of water or storage solution
the probes will dry out and permanent damage will result.
3. Probes must be removed and kept wet during winterization.
4. Replace acid feed tubing annually.
Residential –at least once every three months.
Commercial –every 30 days.
Important Maintenance Information:

Maintenance –Probe Cleaning
Page 4
Step 1
Unscrew & remove the probes from
the flow cell chamber.
Step 2
Step 3
Clean the probe tip and white reference area
with a soft tooth brush and regular
toothpaste or liquid dish washing detergent.
Step 4
Rinse with fresh water, remove and replace
the Teflon tape, & reinstall the probes.
Finally recalibrate the probe (Page 5 for Pro
Logic or Page 6 for Aqua Rite Pro).
Disconnect the probe connectors
from the flow cell.
Note: During the cleaning process it is crucial to keep the tips of both the ORP and pH probes wet. If the probes dry out
they will be incapable of providing an accurate reading.

Calibrating the pH Probe (Pro Logic)
Press the ‘Menu’ button until ‘Maintenance
Menu’ is displayed.
Step 1
Step 2
Press the right arrow button one time and press
the plus (+) button to enter pH calibration.
Step 3
Use the plus (+) or minus (-) keys to increase or
decrease the pH value.
Step 4
Press the right arrow key to show current reading
and new results. Press the right arrow again.
Press the plus (+) key to save the value.
Step 5
Press the right arrow key twice to complete the
calibration.
Step 6
Always verify that the pH probe is clean prior to running the calibration procedure. Also, when testing the pH reading
independently, it is important to obtain test water from the flow cell chamber (where the probes measure the water).

Press the ‘Settings’ button shown above. The
‘Settings Menu’ will appear.
Press the right arrow button three times and
press the plus (+) button to enter pH
calibration.
Use the plus (+) or minus (-) keys to increase
or decrease the pH value.
Press the right arrow key to show current
reading and new results. Press the right arrow
again.
Press the plus (+) key to save the value.
Press the right arrow key twice to complete
the calibration.

Resetting the pH/ORP Timeout Error
Page 7
ProLogic Aqua Rite Pro
Press the ‘Menu’ button until the ‘Default Menu’ appears.
Press the right arrow button until the ‘pH/ORP Timeout –
Chk Feedr’ appears.
Press the plus button (+) to clear the error.
Press the ‘Info’ button shown above. The ‘Info
Menu’ will appear.
Press the right arrow button until the ‘pH/ORP
Timeout –Chk Feedr’ appears.
Press the plus button (+) to clear the error.

Step 3

If not connected, plug in and reboot the system. If
connected or error does not go away, power unit
up and go to step C.
Check System Light On
CSM Comm Error
‘CSM Comm Error’ (Chemistry Sensing Module) will appear with the sensing module is not communicating with
the main circuit board.
With the power off, verify the CSM
cable is plugged in.
Step B
Verify the CSM cable is not cut,
kinked or damaged in any way.
Step A
If the cable is damaged then it will need to be
replaced. If the cable does not have any
damage, go to step B.
