Pump Alternation
The TCU includes a pump alternator function that can be used to minimize pump cycle times or equalize pump run times.
When enabled, the alternator updates each time it starts a pump. If a pump fails to start, the alternator advances to the next
available pump. Pumps can be taken out of service with the H-O-A switches and the TCU will continue to alternate the
remaining pumps.
The following alternation options are available:
• Alternate among all available pumps.
• Alternate between pumps 1 and 2 (High Service Pump option).
• Alternate between pumps 2 and 3 (Jockey Pump option).
• Disable pump alternation
