Alternate Duty Backup (P111 = 53) [MR 200]
Alternates the lead pump each time the material level cycles.
Please note that this feature applies to the MultiRanger 200 only.
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 can RUN only one at a time.
Relay Table
Service Ratio Duty Assist (P111 = 54) [MR 200]
Selects the lead pump based on number of hours each pump has run and the specified
ratios that each pump requires. Multiple pumps can run at one time.
Please note that this feature applies to the MultiRanger 200 only.
Relay Operation (for P118 = 2) [MR 200]
Please note that this feature applies to the MultiRanger 200 only.
The setpoints associated with the relays are grouped so they can be redistributed based
on pump RUN time ratios. The next pump to start or stop is the one with the required time
to actual time ratio.
Over time the number of hours demanded of each pump will conform to the ratios
specified. Usually, the ratios are specified in percent values.
