MODES OF OPERATION DESCRIPTION
The Econ FP is a flow activated pump and will accept a dry contact signal or a 12-24VAC/VDC
signal from any control equipment that responds to flow. The pump runs at a set time or a
set speed according to the mode of operation selected. The run time or the pump speed is
adjustable from10% to100% in 1% increments. The control panel displays the modes of
operation as SECONDS, AUXILIARY and FLOW SWITCH.
Before programming, review the pre-programming requirements pages 13 to 14, steps A-D.
In the Seconds mode, the pump can receive a dry (non-voltage) contact signal and will run
for a set time in response to receiving the signal. The pump can receive the signal from, for
example,a water meter or control valve that sends a dry contact signal. There is a choice of
five pump operating time ranges and the maximum time is displayed in the control panel;
the run time is adjustable from 10% to 100% in 1% increments.
1 SECOND = 0.1 to 1.0
5 SECONDS = 0.5 to 5.0
10 SECONDS = 1.0 to 10.0
20 SECONDS = 2.0 to 20.0
60 SECONDS = 6.0 to 60.0
In the Auxiliary mode, the pump can accept a 12-24VAC/VDC signal and will run at a set
speed for as long as it receives the signal. The pump speed is adjustable from 10% to
100% in 1% increments. If polarity is reversed when connecting a DC signal to the AUX
input, the pump will not respond to the signal. The pump can receive the signal from a
control valve or another type of control equipment that responds to flow.
In the Flow Switch mode, the pump will accept a dry (non-voltage) contact signal from a
2 wire flow switch and will run at the set speed for as long as it receives the dry contact.
The pump speed is adjustable from 10% to 100% in 1% increments. The connection is not
polarity sensitive (polarity is not an issue when connecting the flow switch wires).
