Pump Station Controller
Introduction
This application uses the MicroLogix 1400 and PanelView Component C600
to provide a "stand alone" multifunction pump controller that allows the user
the ability to choose between a pump down (lift station), pump up (water
tank), or a pressure follower (water distribution) control process, with just a
few simple screen selections.
Functionality includes:
● Control of up to 4 pumps.
● User assignable inputs.
● Use of floats, analog or a combination of both to control the process.
● Control of VFDs through Modbus communication, which reduces the
control wiring to the drives (PowerFlex 4/40/400 VFDs only)
● Pump control can be done with starters, PowerFlex 4 series VFDs or
with another manufactures VFD.
● Pump sequencing control.
● User selectable alarms with the ability to choose which ones can be used
to initiate an alarm dialer (user supplied)
● Pump statistics.
● The ability to save and load VFD parameters from the HMI. (PF4
VFDs only).
● Selectable pump interlocks.
● Screen access security.

2. Press Next to proceed to the Measuring Setup screen.
From the Measuring Setup screen you can:
– Use the Up/Down buttons to select the primary measuring device.
If Pressure Follower mode is selected then Analog "In 0" is the only option for
the primary measuring device.
– Select a secondary measuring device
If the primary measuring device is an analog device, you can assign a float to be
used as backup (not available if primary measuring is floats).
– Use the second analog input (IN 1) to measure flow rate from an
analog transmitter or as the process variable if the default analog
input (IN 0) fails.
When analog input "IN 1" (I:1.1) is set for Flow the flow is totalized
using a calculation in the PLC. A more accurate way to totalize would
be to use digital input I:0/0 as a totalized pulse.

3. Press Next to proceed to the Motor Control Setup screen. In the
example shown, four pumps have been configured; the screen will only
display as many pumps as you set up in the initial configuration screen.
From the Motor Control Setup screen you can use the Up/Down
buttons to select the pump control device.
The Starter and Other VFD selections use physical outputs from the
PLC to control the start/stop operation of the motors, while the
PowerFlex 4 option uses Modbus communication to control the VFD.
4. Press Next to proceed to the first Digital Inputs Assign screen. There
are four Digital Inputs Assign screens in total.
From the first Digital Inputs Assign screen you can:
– Use Digital input I:0/0 as a pulsed input to totalize flow only or to
totalize flow and calculate a flow rate.
Publication IASIMP-QS037A-EN-P - May 2013 9
Chapter 1
As a flow totalizer this can be very accurate. However, using it to
calculate flow rate is not as accurate as using analog input I:1.1 as a
flow rate input.
– Press Enter Gallons Per Pulse to set the appropriate gallons per
input pulse
5. Press Next to proceed to the next Digital Inputs Assign screen.
From the remaining Digital Inputs Assign screens you can:
– Press Normally Open or Normally Closed to set the state to
match the way the digital input is wired on the field device.
– Use the Up/Down and End/Home buttons to scroll through the
list of selections
– Digital inputs I:0/0 – I:0/17 are assignable to any of the 31
selections listed; however, depending on the application, they may
not all be applicable. For example, if you only have two pumps in
your system, selection #20 Pump 3 seal fail would not apply

If during the measuring
buttons will enable or
device setup, floats are
selected as secondary
(backup) then these
disable the pumps from
running in backup mode.
– Press Next to proceed to the Backup Pump Select screen.
The Backup Pump Selection screen is visible only if Float is selected as the
backup on the Measuring Setup screen.
Press the Delay Between Pump Starts (Seconds) to enter the delay
before the next one starts when more than one backup pump is enabled.
If on the “Measuring Setup” screen (above) the “Secondary (backup) Measuring
Device” is set to “NOT USED”, then no pumps will run in backup.
If on the “Measuring Setup” screen (above) the “Secondary (backup) Measuring
Device” is set to “Floats”, then backup pumps will start when the “Lead Start”
float is activated, and continue until the “Pumps Stop” float is activated.
A “lead start” and a “pumps stop” selection must be assigned to an input on
one of the “Digital Input Assign” screens.

Because this is a backup operation likely due to a failure, the pumps do not
alternate.
Setup Examples
Example 1: In a pump
down application. Floats
are being used as backup.
On the Pump Sequence
Setup screen, the Primary
selection for all pumps is
set to Alternate, and the
Secondary selections are
set to Lag1. And on the
Backup Pump Selection
screen, lead, lag1 and lag2
pumps are all allowed to
run as backup. As the level rises and activates the Lead Start float. The lead
pump (because all are set for alternate, it could be any of the four pumps)
starts. Let’s say that the Delay Between Pump Starts (see graphic above) is
set for 60 sec. If the Pumps Stop float does not clear in this time, all of the
pumps assigned to Lag1 as Secondary will start (in this case all of them). If a
pump was set to Lag2 as the Secondary selection, it will start 60 sec. after the
Lag1 pump(s) start. If all of the pumps are set to Lag2 as Secondary, then no
pumps will start during the first 60 sec. (Lag1 time). The sequence is: lead
pump --- delay --- lag1 pump(s) --- delay --- lag2 pump(s). Once a pump starts,
it will continue to run until the Pumps Stop float clears.
Example 2: Same setup as
above except the
Secondary selections are
now as shown. Let’s say that
pump 2 is the lead pump.
Lead Start float is activated.
Pump 2 starts --- 60 sec.
time delay --- pump 1 (lag1) starts --- 60 sec. time delay --- pump 3 (lag2) starts.
Because pump 4 is set to Not Used it does not run.
Example 3: The setup is as
shown, however now the
Lag1 pump is not allowed
to run in backup. Again,
let’s say that pump 2 is the
lead pump. Lead Start float
is activated. Pump 2 starts
--- 60 sec. time delay --- and
although pumps 1 and 3 are
both set for lag1, they do no

run because the lag1 pumps are not allowed to run due to the selection on the
Backup Pump Selection screen --- 60 sec. time delay --- pump 4 (lag2) starts.
Configuring Analog Inputs
Now that the application has been set up, you can continue through the rest of
the configuration.
1. From the Main screen, press Analog Inputs Config to display the
configuration screen.
This button is not visible unless an analog device is being used
(Measurement Setup screen).
The screen includes displays showing the raw data coming from the
analog input card and mA value of the input from the calibrated (zero
and span set) card.
2. Select one of the two following calibration methods:
– Apply a 4mA signal to the cards input (I:1.0), then push Apply a
4mA Signal To Analog "In 0" to make the zero adjustment. After
making the zero adjustment, choose Apply a 20mA Signal To
Analog "In 0" to make the span adjustment if a signal is available.
– Select No 4-20mA Signal Available? to calibrate the analog input
using the card's default values if no current calibrator is available.
You must use one of these calibration methods to ensure proper operation.
3. Enter a scaled value in the Enter 4mA Signal Value field. For example:
0 Ft.
4. Enter a scaled value in the Enter 20mA Signal Value field. For
example: 10 Ft.
