The “CHECK SYSTEM” LED will alert you when the AquaRite Pro LS detects any of the following conditions that are abnormal and require attention for the optimal operation of your pool. Press “<“ or “>” to view all of the existing “Check System” conditions.
Solution:
- Inspect Cell — For optimum operation, you will need to inspect the AquaRite Pro LS chlorinator cell approximately every 3 months and clean the cell if necessary. The AquaRite Pro LS will automatically remind you when it is time and display “Inspect Cell, + to reset” as part of the rotating Default Menu. Clean the cell (see instructions, page 11) and then press the “+” button during the “Inspect Cell” display to reset the timer.
- High Salt/Amps — The AquaRite Pro LS will stop generating chlorine under certain high salt conditions in order to protect the internal electronics from damage. The only way to lower the salt level is to partially drain the pool and add fresh water.
- Chlorinator Cell Sensor — The cell sensor is either an open or short circuit.
- Low Volts — If the chlorinator cell voltage is too low.
- No Cell Power — If no chlorinator cell power is detected on the printed circuit board.
- Check Flow Switch — If the flow switch input is invalid.
- Cell Power Error — If a chlorinator cell power error is detected on the printed circuit board.
- Cell Missing — If the chlorinator is enabled but no cell is detected.
- CSM Comm Error — If Chemistry Sensing is enabled and the Chemistry Sense Module (CSM) is not responding.
- pH Probe Error — If the CSM indicates that there is a problem with the pH probe.
- pH Low – Check Feeder — If a pH level of 6.9 or less is detected, check the feeder for proper operation
- pH High – Check Feeder — If a pH level of 8.1 or higher is detected, check the chemical supply and the feeder for proper operation
- pH Timeout – Check Feeder — If the unit has been dispensing for more than the selected timeout without reaching the desired level. Check the chemical supply and the feeder. If both are OK, the timeout may need to be increased. Press the “+” button to reset the alarm and resume dispensing.
- ORP Probe Error — If the CSM indicates that there is a problem with the ORP probe.
- ORP Low – Check Chlor — If an ORP level of 350mV or less is detected. Check the chlorinator for proper operation. Check the salt level (> 1.2 g/l)
- ORP High – Check Chlor — If an ORP level of 950mV or higher is detected. Check the chlorinator for proper operation.
- ORP High – Chlor Off — If an ORP level of 950mV or higher is detected and the chlorine feed mode is ORP Auto Sensing, the chlorinator has been turned off. Check the chlorinator for proper operation.
- ORP Timeout -Chlor Off — If the unit has been chlorinating for more than the selected sanitizer timeout without reaching the desired level, the chlorinator has been turned off. Press the “+” button to reset the alarm and resume chlorination.
- Ambient Sensor — If the internal (ambient) sensor is either open or short circuit.
