Pressure Tank Recommendations:
Minimum tank size is 2 gallons. Use a pre-charged pres-
sure tank with the Drive. The tank size must equal at least
20% of the pump's rated flow in gallons per minute
(GPM), but cannot be less than 2 gallons capacity. For
example, a pump rated at 7 GPM would require a tank of
2 gallons capacity or larger. A pump rated at 50 GPM
would require a 10 gallon tank or larger. A larger tank may
increase cycling of the pump.

NOTE: Do not connect the clear wire on the transducer cable to any terminal; instead, tie it back with
electrician's tape so that it cannot touch any other components or connections.

NOTE: Set the pressure tank's pre-charge to 70% of the
system operating pressure. When using an external set
point as well as an internal set point, pre-charge the tank
to 70% of the lower set point of the two. Some applica-
tions may require a different percentage when figuring the
set point.
Transducer Connections (See Figure 5):
Use the transducer provided with the drive. Install the
transducer downstream of the tank. Install the transducer in
a tee in a straight section of pipe with at least 1 foot of
straight pipe on each side of the tee (that is, all fittings
must be at least one foot away from the transducer).
Feed the transducer cable through the open 1/2" conduit
hole on the bottom of the drive enclosure.
The transducer terminals, marked AI+ and AI-, are located
to the left of the output terminals. Connect the red wire of
the transducer cable to AI+, connect the black wire to AI–,
and connect the cable shield to the metal lug to the right.
NOTE: Do not use the clear wire on the transducer cable
for any connections; tape the end and tie it back to the
cable with electrical tape so that it does not touch any
other components or connections.
Note: To connect the wires;
1. If the wire ends are not pre-stripped, strip them back
about 1/2".
2. Push the spring terminals up (back).
3. Insert the wires.
4. Release the spring terminals.
