Application #5
Capturing, Diagnosing, & Correcting Equipment Problems
Application 5: You have a site that just reported a PLLD Shutdown on line 4 Diesel. Your site is down and you cannot get a technician to the site for at least three hours. What can you do?
Solution: You can use the Infinity Services to communicate directly with the tank gauge at the site. You can run the VR Pressure Line Leak Diagnostic Report to verify that the no one has the diesel pump handle on (The PLLD test needs to have all diesel pumps turned off.). If you have the optional camera server, you can click on the Current Image button to see who is on site. You can run the site controller DISABLE PUMP command using the Infinity Run Command feature to make sure no one turns a pump on during the test. You can then run the VR Start Pressure Line Leak Test Line 4 (3.0 GPH in V18+). This report will restart the test and if it passes the pumps will restart. You can verify the status by running the VR Pressure Line Leak Diagnostic Report again. You will want to run the report a couple of times to verify the end of the test. To make sure the alarm has cleared, run the VR Active Alarm report. When you are finished you can re-enable the pumps through the Infinity run command feature.
