• • 500 SERIASTALLATION INSTRUCTIONS <br /> b. Testing Model 516 Discriminating Sensor If using the Model 516 <br /> Discriminating Sensor, the sensor can be tested by placing it in fuel or water to alarm. To test <br /> the 516 sensor in fuel, place it into a cup of fuel that is shaded from direct sunlight (the sensor is <br /> optical and needs to be tested in dark conditions). When the sensor is placed into fuel, the 522 <br /> Monitor will immediately alarm for fuel and all shear valve cables should be tripped within 3-4 <br /> seconds. Power will also be shut off to the dispenser within 10-12 seconds. After the shear <br /> valves have been tripped, remove the sensor from the fuel and clean with alcohol and a clean <br /> paper towel. Wipe off the optical cone inside the sensor with the alcohol and towel. Reset all <br /> shear valves as set forth on page 7. If testing for water, place the sensor in water—the 522 <br /> Monitor will alarm for water as long it remains in water and will stop when removed from the <br /> water. <br /> C. Testing Model 406-5 Liquid Level Sensor If using the non- <br /> discriminating Model 406-5 Sensor, the sensor can be tested by placing it in water to alarm. <br /> Make sure that the test is done in a bucket or cup shielded from direct sunlight. When the sensor <br /> is placed into the water or fuel,the 522 Monitor will alarm for fuel and all shear valve cables <br /> should be tripped within 3-4 seconds. Power will also be shut off to the dispenser within 10-12 <br /> seconds. Reset all shear valves as set forth on page 7. If fuel is used for the test instead of water, <br /> remove the sensor from the fuel and clean with alcohol and a clean paper towel before mounting <br /> in the sump. <br /> Testing Note: All Beaudreau sump sensors have been third-party <br /> tested and are EPA-listed interstitial liquid sensors.
