Overfill Protection Testing Testing Procedure <br />25 <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 />Testing <br />ATurn off power to the console. <br />BDisconnect the probe from the field wiring and remove it from the riser. <br />If you are testing more than one tank remove all the probes from their risers. <br />CLay the probe safely on the ground and reattach the field wiring. <br />DPosition the water float at the bottom of the probe and the product float 25% up from the bottom of the฀ <br />probe. <br />EPower the console back on. <br />FSimulate a delivery as follows: <br />Move the float towards the top of the probe at a rate of 1-2” per ten seconds. <br />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 />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 />GOnce the float reaches the overfill level the Overfill alarm, including external Overfill alarm (if present), will฀ <br />sound. <br />HSilence the Overfill alarm on the TLS and external Overfill alarm (if present) by acknowledging it. <br />IMove 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 />JRepeat 3f - 3i for the other probes. <br />Test Completion <br />APrint out the delivery report for all tanks tested. <br />BPower off the console. <br />CReplace the probes back into the tank; before inserting into riser, ensure that the floats are positioned at the฀ <br />bottom of the probe. <br />DPower on the console. <br />EIf the console is running BIR enter a manual adjustment for the amount of the delivery. <br />FIf 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.
