Hayward Pro Logic® Model: PL-PS-4 PL-PS-8 PL-PS-16 PL-PS-16V Operation - Page 45

• pH Timeout - Check Feeder -- If the unit has been dispensing pH 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. • pH Calibration Error -- When using the pH Calibration Wizard and the entered test result was different from the measured pH level by ± 1.0 or more. The pH probe may need to be cleaned or replaced. • 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. • 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 Pro Logic internal temperature sensor is either an open or short circuit. For helpful troubleshooting information on any of these issues, go to the Diagnostic Menu and then scroll through the various items until you see the cause for the "CHECK SYSTEM" LED being illuminated. Diagnostic Menu To enter the Diagnostic Menu, press the "Menu" button repeatedly until the display shows "Diagnostic Menu". At this point, you can use either the "" buttons to scroll through the various menu items which are described below: +S2e3t.4D5ay an+d6T.i7m5eA W84e°dFnesd3ay2010P:3P7MP Press to switch chlorinator operation to opposite polarity (15 second delay) Move to previous/next menu item +/- 23.45V is the voltage applied to the chlorinator cell +/-6.75A is the current (amps) through the cell 84ºF is the water temperature at the cell 3200PPM is the "instant" salt level at this time This display will be shown only if the chlorinator is enabled. For the chlorinator to be operating, several other things must be happening: the filter pump must be running, the flow switch must be detecting flow, the chlorinator setting must be set greater than 0%, the water temperature at the cell must be between 50ºF and 140ºF, and the salt level must be within the operating range. If any of these conditions are not met, the chlorinator diagnostic display will tell you the reason. It's possible to have more than one reason, in which case after you rectify what was displayed the first time, a second display will appear. If the current (amps) display is 0.00A, then the chlorinator is operating normally but is in the off part of its normal operating cycle. Simply press either the "+" or "-" key to start a new cycle. The Pro Logic periodically reverses the polarity of the voltage applied to the cell in order to automatically clean off any calcium deposits. It is important that you check the chlorinator operation in both polarities. To do this, press either the "+" or "-" buttons and the chlorinator will turn off, wait for 15 seconds and then turn on in the opposite polarity. 42
