Scope <br />This procedure will provide a Veeder-Root ATG certified technician a procedure to safely test tank overfill <br />protection. <br />Reference Documents <br />• Veeder-Root TLS-3XX Operators Manual (576013.610) <br />• Veeder-Root TLS-3XX Setup Manual (576013-523) <br />• Veeder-Root TLS -450 Setup and Operation Screens Manual (577013-940) <br />• Veeder Root TLS-450PLUS/TLS4 Operator's Manual (577014-110) <br />• Veeder-Root TLS4 Quick Start (577014.034) <br />• Veeder-Root Overfill Alarm Installation Guide (576013.589) <br />Consoles <br />TLS-450PLUS, TLS4c, TLS4i, TLS -450 and TLS3XX <br />Requirements <br />TLS-450PLUS. TLS4c, TLS4i, TLS -450: Automatic Event: Device Task programmed to trigger on Tank Overfill and <br />close a relay feeding voltage to the Overfill alarm device. <br />TLS-3XX: Output relay programmed to close a relay on a Tank Overfill alarm feeding voltage to the Overfill alarm <br />device. <br />Testing Procedure <br />1. inspection <br />a. Verify the levels in the tank to make sure there is product in the tank and that the tank is enabled. <br />b. If the site is currently receiving a delivery, wait until the delivery is complete, <br />c. If the tank is performing a SLD tank test, stop the test. <br />2. Preparation <br />a. Turn Alarm filtering off, as this will allow you to clear alarms quicker. Refer to TLS-3XX Setup manual <br />(576013.623) or TLS4XX on-line help. <br />b. Program Delivery delay to 1 minute, this will allow the delivery to be completed quicker. <br />i. Note the customers original value, so you can restore it after the test. <br />24 <br />
