500 SERIE STALLATION INSTRUCTIONS <br /> How the 500C Controller System and 522 Remote Monitoring SystemWork <br /> The 5000 Controller System is installed at the gasoline dispenser and is capable of monitoring <br /> up to 3 sensors. If a fuel leak or high water condition is detected in dispenser containment, the <br /> 5000 Controller System will actuate a solenoid that will trigger all product line shear valves. <br /> When any of the 3 sensors goes into alarm (fuel, water or impact), the 500C Controller will <br /> immediately send the alarm status over the dispenser's AC power line. This transmission will be <br /> received by the 522 Remote Monitoring System that is installed inside the station. The 522 <br /> Remote Monitoring System provides an audible and visual alarm inside the station to alert the <br /> station operator of the problem. It can also be used to shut off power to the dispensers and <br /> turbines. Finally, the 522 Remote Monitoring System is equipped with an output that can alert a <br /> third-party monitoring system such as a TLS-350 that there is a dispenser problem that requires <br /> attention (see Installation Instructions for 522 Remote Monitoring System). <br /> At the Dispenser Inside Station <br /> 500C Controller System 522 Remote <br /> Y Signal Transmission <br /> Over AC Powerline Monitoring System <br /> Sensors Detect Fuel, Water or <br /> Dispenser Impact <br /> Monitors for fuel, water or <br /> Controller Triggers Shear Valves impact alarms.
