Inspection <br />Verify the levels in the tank to make sure there is product in the tank and that the tank is enabled. <br />If the site is currently receiving a delivery, wait until the delivery is complete. <br />If the tank is performing a SLD tank test, stop the test. <br />2. Preparation <br />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 />Program Delivery delay to 1 minute, this will allow the delivery to be completed quicker. <br />1.
