Frequent stop/start protection. Supplied standard on all multiplex systems. Allows each pump to run a minimum
amount of time. Frequent stop/starting can reduce coupling life and is also less efficient from a power consumption
standpoint.
Automation alternation. Supplied standard on all multiplex systems. Allows the pumps to alternate. The primary
feature of automatic alternation is to equalize the run time on all of the pumps.
Troubleshooting
This troubleshooting chart is intended as a basic troubleshooting guide. We recommended that you consult your local
dealer for service. Each Travaini Rotary Vane Vacuum Pump system is tested and checked at the factory. Always indicate
system model and serial number when calling.
WARNING: Before attempting any repairs, remove all power from the system by switching off the main breaker or
disconnect switch. This prevents the system from automatically starting from a vacuum switch.
