Hayward Pro Logic Model: PL-P-4 Operation - Page 7

Troubleshooting and Diagnostic Information The Pro Logic 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 Department from Monday through Friday, 8AM to 8PM EST at 888921-7665. 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 Pro Logic will remain in this mode of operation until manually taken out of service mode. Pressing the "SERVICE" button again will cause the Pro Logic to switch to service-timed mode which is very similar to service mode, except that the Pro Logic 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/keypad(s). Pressing the "SERVICE" button again, will return the Pro Logic to normal (automatic) operation. Check System Indicator The "CHECK SYSTEM" LED will alert you when the Pro Logic 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 Pro Logic chlorinator cell approximately every 3 months and clean the cell if necessary. The Pro Logic 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 30) 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 Pro Logic 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 Pro Logic 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 Sensor -- If the water 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 the solar sensor is either an open or short circuit. • Chlorinator Cell Sensor -- If the chlorinator function is enabled (Configuration Menu/Chlorinator) and the cell sensor is either an open or short circuit. 31 Lights, Aux1 and Aux2 Outputs Standard Relay: Manual operation of all 3 relays is identical. Assuming that the relay is currently off, simply press the appropriate button to turn on the relay. If the relay does not turn on, it probably is due to the "interlock" feature (which was set up in the Configuration Menu) being activated that requires the filter pump to be running and the valves to be in the pool-only position. This protects pumps and other equipment from possible damage. If the controlled output is on, pressing the appropriate button again will turn off the relay. Manual turn off is disabled if the "Freeze Protection" feature is enabled and the air temperature is less than the selected freeze temperature threshold. Dimmer Relay: If Lights or an Aux output is configured as a dimmer, pressing the corresponding button will generate a temporary display which shows the dimmer output level (Off - On 100%). Pushing the "+" or "-" button changes the level in increments of 20%. When the desired output level is displayed, press the corresponding button again to turn off the display and return to normal operation. When the Lights or Aux output comes on again (either manually or automatically), the dimmer output level will be the same as the last time that it was set. VSP Relay: This selection is used to configure a Lights/Aux output to supply power and control a Hayward Variable Speed pump (VSP). External Input Interlock: If enabled, this function will force the Lights or Aux off when the external input is active. External Input Interlock will not have precedence over Freeze Protection for Lights and Aux outputs. Pool/Spa Valves Pool-only or spa-only systems: The POOL/SPA button has no function. Pool and Spa systems without spa spillover: In pool-only mode, the left LED next to the POOL/SPA button is illuminated. Pressing the POOL/SPA button will switch the Pro Logic to spa-only operation (right LED illuminated). Pressing the POOL/SPA button again will switch back to pool-only. Note that the filter pump will turn off while the pool/spa valves are turning. Pool and Spa systems with spa spillover: In pool-only mode, the left LED next to the POOL/SPA button is illuminated. Pressing the POOL/SPA button will switch the Pro Logic to spa-only operation (right LED illuminated). Pressing the POOL/SPA button again will switch to spa spillover operation (both LED's illuminated). Pressing the POOL/SPA button again will switch back to pool-only. Note that the filter pump will turn off while the pool/spa valves are turning. External Input Interlock: If enabled, this function will force the Valve off when the external input is active. External Input Interlock will not have precedence over Freeze Protection for Valve outputs Service The main unit keypad has a SERVICE key. This button 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, and the remote display/ keypads are disabled (except for manual turn off for emergencies). The red SERVICE LED will be illuminated and the Pro Logic will remain in this mode of operation until manually taken out of service mode. Pressing the SERVICE button again will cause the Pro Logic to switch to service-timed mode which is very similar to service mode, except that the Pro Logic 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/keypad(s). Pressing the SERVICE button again, will return the Pro Logic to normal (automatic) operation. See Troubleshooting/Diagnostic Information (page 30) for more information about the service modes. 4
