If the site is extremely busy,especially if blenders are present,there may not be sufficient idle time to complete a Periodic or Annual test unless the station is shut down. 6. Dispenser programmed to turn On all pumps when only one product is to be used. 7. Test was not scheduled. Setup Daft Warning This alarm occurs if an error was made in programming.This alarm will also occur if the line length has not been programmed.The line length default is 501 feet and will cause a SETUP DATA WARNING if the Service Contractor does not enter the line length. IMPORTANTI The default line type is set to FLEX A(white Enviroflex PP1501).If the actual line type is not FLEX A,and the Service Contractor does not select the correct line type,the result may be a line test failure. Troubleshooting Field Leak Testing Problems This procedure is for sites,which when tested per Veeder-Root documents,fail to produce shutdowns when a calibrated leak is applied to the line. The following steps are necessary to identify the cause of the failure.It is necessary to retest after each step. 1. Verify that the console has been programmed to shut down on 3 gph line test failures. 2. Verify that the pump relay is not sticking,causing the STP to stay On when the console is trying to shut it down. 3. Verify that the PLLD/WPLLD transducer is measuring within 5 psi of actual line pressure.Replace transducer if necessary, purge the line of air,and perform 3 gph test. 4. Verify that the seating pressure of the check valve is between 17-25 psi.If the check valve seating pressure is outside of this range, replace it and purge the line of air. 5. Remove and replace the siphon jet assembly from the FE Petro pump(P/N 400562901).This device eliminates air from getting into the piping system.If air enters the piping system,it affects the bulk modulus of the line and will shift leak thresholds.If a defective jet assembly is found,it is necessary to fully purge the line. 6. If the console has software version 16/116/316 or lower,upgrade the software to the current version. 40 7. In the console line leak setup,increase the piping length by 10 percent and retest the line.If the line passes, the length of piping had been underestimated and should remain at the new length. 8. if the console has software version 23 or higher and is in the"User Defined"mode,verify that the Bulk Modulus value for the line being tested is programmed correctly. Refer to the Line Leak Application Guide(P/ N 577013-465)for approved Bulk Modulus values. 9. If the line fails to produce shutdowns after these steps have been followed,contact Veeder-Root Technical Support for further assistance. 21
