Hayward PL-PLUS Operation Manual - Page 43

Troubleshooting and Diagnostic Information The Aqua Plus 16v provides 2 different tools to aid in troubleshooting any problems that may occur in your pool and/or spa system. The Service mode will allow you to disable automatic operation and manually control most of the equipment (the heater and general purpose Valve3 output are the exceptions). The Diagnostic Menu will provide some detailed information regarding system operation. While both of the features are primarily intended for the use of the professional service technician, their function is fully explained below. If you believe your system is not operating properly or have questions regarding the operation, call the Hayward Technical Service Dept. from Monday through Friday, 8AM to 8PM EST at 908-3557995. Service Mode The main unit keypad has a SERVICE button that is used primarily during servicing of the pool equipment. If you want to completely disable the automatic operation and operate the system manually, you can put the system into Service or Service-Timed mode by pressing the "Service" button. Pressing the "SERVICE" button once will switch the system into service mode which means that all automatic functions are disabled, the optional remote display/keypads are disabled (except for manual turn off for emergencies). The outputs can be manually controlled by pressing the buttons on the local display/keypad. The red "SERVICE" LED will be illuminated and the Aqua Plus 16v will remain in this mode of operation until manually taken out of service mode. Pressing the "SERVICE" button again will cause the Aqua Plus 16v to switch to service-timed mode which is very similar to service mode, except that the Aqua Plus 16v will automatically return to normal operation after 3 hours. During service timed operation, the "SERVICE" LED will flash and the time remaining will be displayed on the remote display(s). Pressing the "SERVICE" button again, will return the Aqua Plus 16v to normal (automatic) operation. Check System Indicator The "CHECK SYSTEM" LED will alert you when the Aqua Plus 16v detects any of the following conditions that are abnormal and require attention for optimal operation of your pool. Press "" to view all of the existing "Check System" conditions. • Inspect Cell -- For optimum operation, you will need to inspect the Aqua Plus 16v chlorinator cell approximately every 3 months and clean the cell if necessary. The Aqua Plus 16v will automatically remind you when it is time and display "Inspect Cell, + to reset" as part of the rotating Default Menu. Clean the cell and then press the "+" button during the "Inspect Cell" display to reset the timer. • Low Salt/Minerals or Very Low Salt/Minerals -- When the salt is too low the Aqua Plus 16v will generate less chlorine and the life of the cell is degraded. Check the cell and clean if necessary before adding salt. • High Salt/Amps/Minerals -- The Aqua Plus 16v 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. • Water/Pool Sensor -- If the water or pool (if Dual Equipment) sensor is either an open or short circuit. • Air sensor -- If the freeze protection feature is enabled (Configuration Menu/ Filter Config.) and the air sensor is either an open or short circuit. • Solar sensor -- If Solar is enabled and the solar sensor is either an open or short circuit. • Spa sensor for Dual Equipment-- If dual equipment spa sensor is either an open or short circuit. • Chlorinator Cell sensor -- If the chlorinator function enabled (Configuration Menu/Chlorinator) and the cell sensor is either an open or short circuit. 40
