P122 Pump Service Ratio [MR 200]
Selects pump usage based on the RUN time ratio rather than last used.
This parameter only relates to relays with P111 = 54 or 55.
To make this parameter useful, assign it to all of the pump relays. The number assigned to
each pump relay represents the ratio applied to decide the next pump to start or stop.
Independent Relay Failsafe (P129)
P129 Relay Failsafe
Sets the failsafe operation per relay to allow for more flexible programming.
Use this for operations independent of the Failsafe Material Level (P070).

• P070 Failsafe Timer
• P111 Relay Control Function
Notes:
• All pump control relay ON and OFF setpoints must be the same value
• If the level is within 5% of Span (P007) of the OFF setpoint, the next pump is not
started
Notes:
• The MultiRanger will not sacrifice other pumping strategies to ensure that the ratio
is held true
• If the pump relays are set to the same value then the ratio equals 1:1 and all pumps
are used equally (preset)
