Setting a Pump to Run On [6 relay model]

When you need to pump below the normal OFF setpoint, use P130 (Pump Run-On Interval)
and P131 (Pump Run-On Duration) to control this event.
Example:
The pump connected to Relay Three is set to pump for an extra 60 seconds every 5 hours.
Parameter
P130
P131
Note: P130 counts when the indexed relay is tripped, not the number of pump
cycles. If the indexed relay only trips once every four pump cycles then the actual
interval of the run-on will be 20 pump cycles, or five cycles of Relay Three.

Setting the Pump Start Delays [6 relay model]

The pump start delay ensures that all of the pumps do not start at once to avoid power
surges. There are two parameters used here: P132–Pump Start Delay and P133–Pump
Power Resumption Delay. The default is 10 seconds but you can increase this if your
pumps take longer to spin up.
Example:
The delay between pumps is set to 20 seconds and the delay of the first pump is set to 30
seconds.
Parameter
P132
P133

Reducing Wall Cling [6 relay model]

Use the Wall Cling parameter to randomly alter the ON and OFF setpoints over a range.
This eliminates the ridge of material that builds up at the setpoint that can give false
echoes.
This setting may increase the number of days between trips to clean the wet well.
Wall cling reduction is set by P136. The relay setpoints ON and OFF are randomly varied
inside a range so the material level does not stop at the same point.
