MultiSmart Installation & Operation Manual
Figure 136 - Well Cleanout Inhibit Options
These inhibit options are disabled by default. The user can enable these options on this screen. These
options make sure that pumps will be stopped before reaching the pump’s snore point, thus protecting the
pumps during well cleanout. If these options are enabled, then the Delay Adjustment and Level
Adjustment on the Well Cleanout screen are not used and a value of 0 is used for both Delay and Level
Adjustments.
Digital Alias on this screen can be assigned to any digital tag to stop well cleanout when the tag is set.
Under Current Threshold defines the pump under current threshold for inhibiting well cleanout. If the pump
current reaches less than this threshold, well cleanout is inhibited if it is active.
Low Power threshold defines the pump power factor threshold for inhibiting well cleanout. During a well
cleanout, if pump power factor reaches less than this threshold, well cleanout is inhibited.
Low Flow threshold defines the pump station outflow rate threshold for inhibiting well cleanout. If the station
outflow rate reaches less than this threshold during a well cleanout, the cleanout is inhibited.
A value of 0 for any of these thresholds indicates that the particular option is disabled for inhibiting well
cleanout.
16.1.5 Well Washer
A well washer can be controlled by the MultiSmart in order to coordinate its use with the pumping cycles.
Name Description
Enabled? Toggle this value to enable or disable the well-washer feature.
Activation Level Sets the level at which the washer is activated.
Activation Delay Sets a delay after the Activation Level is reached before the well washer is started.
Max On time Maximum run time for the well-washer
Inter-Start Period Ensures the well washer does not run too often
Maximum Off Time
Sets a maximum time the well-washer can be off. This ensures the washer is run at a
minimum interval even if the well level has not reached the activation level.
Table 21 – Well Washer Parameters
NOTE: It will also be necessary to configure a digital output to activate the well washer. In particular,
you will need to set the digital output source to the well washer “active” tag. See Section 14.11 for a
description of how to configure digital outputs.
