Overfill Protection Testing Testing Procedure <br />c. Print the Tank Inventory Report. <br />d. Test the relay assigned to the external Overfill alarm (if present) to insure the Overfill alarm works. <br />1. If the Overfill alarm does not sound, repair the device before continuing testing. <br />3. Testing <br />a. Turn off power to the console. <br />b. Disconnect the probe from the field wiring and remove it from the riser. <br />1. If you are testing more than one tank remove all the probes from their risers. <br />c. Lay the probe safely on the ground and reattach the field wiring. <br />d. Position the water float at the bottom of the probe and the product float 25% up from the bottom of the <br />probe. <br />e. Power the console back on. <br />f. Simulate a delivery as follows: <br />1. Move the float towards the top of the probe at a rate of 1-2" per ten seconds. <br />2. Continue moving the float to the top of the probe at a rate of 1-2" per ten seconds for the next 50 <br />seconds, the probe is now in delivery mode. <br />3. Slide the float at a moderate speed to the top of the probe. Note to not slam the float against the head <br />of the probe, this can damage the float. <br />g. Once the float reaches the overfill level the Overfill alarm, including external Overfill alarm (if present), will <br />sound. <br />h. Silence the Overfill alarm on the TLS and external Overfill alarm (if present) by acknowledging it. <br />i. Move the float down to the bottom of the probe. The TLS will clear the Overfill alarm once the delivery delay <br />time is complete. <br />j. Repeat 3f - 3i for the other probes. <br />4. Test Completion <br />a. Print out the delivery report for all tanks tested. <br />b. Power off the console. <br />c. Replace the probes back into the tank; before inserting into riser, ensure that the floats are positioned at the <br />bottom of the probe. <br />d. Power on the console. <br />e. If the console is running BIR enter a manual adjustment for the amount of the delivery. <br />f. If the site is not running BIR give the delivery report to the store manager so they can log the delivery as <br />part of the overfill testing. <br />25 <br />
