Alternate Duty Assist (P111 = 52)

Alternates the lead pump each time the material level cycles and runs all pumps together.
Relay Operation (for P118 = 2)
The setpoints associated with the relays are grouped so that they can be rotated.
Setpoint one does not relate directly to relay one. The pumping algorithm manages the
mapping of setpoints to relays.
When pumps are run, they RUN in parallel.
