Why are both a cycle indicator switch and a pressure switch used in a Series Progressive system?
The cycle switch signal regulates lube volume (number of divider valve cycles) and results in a time-out fault when not received within the monitor set time. A pressure switch is typically used for fault feedback when a cycle switch is not used, or when relieving indicators are used (blockage will not stop the system) and can provide additional diagnostics to identify the cause of a problem on any Series Progressive system.
