• • 500 SERIASTALLATION INSTRUCTIONS <br /> 5. Testing the Sump Sensors and System <br /> After all sensors have been properly connected,the 522 Remote Monitoring System is installed <br /> and the dispenser is ready for operation, power up the dispenser at the circuit breaker. If the <br /> sensors are connected, the dispenser should power up and operate normally. If the dispenser <br /> does not come on, check all wiring connections and sensor connections—be sure the impact <br /> sensor has been properly reset. <br /> a. Testing Model 510 Discriminating Sensor The Model 510 is a two-part <br /> sensor-the lower part of the sensor is a discriminating "fuel-only"polymer strip (see below) <br /> while the sensor cap contains an optical sensor that is used to detect a high-water condition. <br /> The polymer strip will detect fuel approximately 2- <br /> 3 minutes after being placed in fuel. After it has <br /> been immersed in fuel several times, it is <br /> recommended that it be replaced (replace with <br /> Beaudreau Part#5IORS). This will help prevent <br /> false alarms. The easiest way to test for <br /> functionality is to disconnect the polymer strip to <br /> simulate a fuel leak. When the strip is removed, the <br /> Optical 522 Monitor will alarm for fuel and all shear valve <br /> High Water cables should be tripped within 3-4 seconds. Power <br /> Sensor will also be shut off to the dispenser within 10-12 <br /> seconds. Replace the strip and reset all shear valves <br /> as set forth on page 7. <br /> The high-water optical sensor located in the cap of <br /> the sensor can be tested by placing the entire sensor <br /> into a bucket of water that is shielded from direct <br /> sunlight—make sure the optical cone is beneath the <br /> water level and that no ambient light can get into <br /> the bucket. High water will alarm the same as fuel, <br /> therefore when the cone sees water, the 522 <br /> Replaceable Monitor will alarm for fuel and all shear valve <br /> Discriminating cables should be tripped within 3-4 seconds. Power <br /> Polymer Strip will also be shut off to the dispenser within 10-12 <br /> (Part#51ORS) seconds. Replace the strip and reset all shear valves <br /> as set forth on page 7. <br /> Page 9 <br />
