Example [6 relay model]:
A range of 0.5 meters is used to vary the setpoint. The randomly-selected setpoints are
always inside the ON and OFF setpoints.
Grouping Pumps [6 relay model]
You can group pumps and use the same pumping algorithm separately on each group. If
you specify different pumping algorithms then the pumps are already grouped by
algorithm and you do not need to use this parameter.
Group pumps only when four pumps are using the same algorithm and you want to split
them into two groups.
Example:
Pumps One and Two can operate as a group and Pumps Three and Four can operate as
another group.
Setting a Flush Valve [6 relay model]
A flush valve stirs up the sediment on the bottom of the well during pumping so that it
doesn’t accumulate. These parameters will control any relays set with P111 = 64 (Flush
Valve).
Most sets of parameters will work with only one or two changes; however, for these
parameters to work, all of them must be set to a value.
