CHAPTER 4 - PLACING SYSTEM INTO OPERATION
It is suggested the following sequence be used when the PCS140e.1 is started for the first time. If, at
any time, the expected result is not obtained, see the troubleshooting chapter. Before applying power
to the unit inspect all wiring
4.1-Supplying Power to the System
Check that the supplied voltage is 120 VAC (+/- 10%). Turn all of the pump Hand-Off-Auto switches
to the ‘Off’ position. Turn on the main power breaker. The PLC will power up and the HMI will display
the Main Menu screen. Verify that there is adequate water level in the source tank (above LWCO level).
4.2-System Setup and Configuration
The system needs to be configured to reflect the various options that are required the specific
installation.
Setting System Options
1.From the main menu screen, access the Setup Screen Menu by pressing the ‘F2’ button.
2.After entering the correct password, select “System Options”
3.Enter the correct password for access to the System Option screen.
4.Enter the correct number of pumps (2, 3 or 4) for the system.
5.Enter the correct units for the header pressure (psi, kPa, or bar).
6.If Modbus data monitoring is desired, turn the Modbus port on by pressing the button. The Modbus address has
a default value of 1. A different value may be entered at this screen.
7.Press ‘F1’ to return to the System Setup menu.
I/O Configuration/verification
1.Select “I/O Config” from the System Setup menu.
2.At the I/O Config menu, select the “Analog In Config” button.
3.Enter appropriate parameters for the header pressure transmitter. Typically, the ‘Raw’ signal values will be 4 and
20 mA. The Scale values should correspond to the range of the transmitter in the selected units of measure-
ment (psi, kPa or bar). The actual values for the input signal and the scaled signal are displayed.
4.Press ‘F1’ to return to the I/O Config menu.
5.Select the ‘Digital I/O’ button.
6.Turn each H-O-A switch to the ‘Auto’ position and verify that the correct inputs are highlighted.
7.Return each switch to the ‘Off’ position and verify that the inputs return to a non-highlighted state.
8.Turn each H-O-A switch to the ‘Hand’ position and then back to the ‘Off’ position. Verify that each pump starter
pulls in and the correct pump runs. Verify that the correct ‘Pump Running’ input is highlighted while the pump
is on and returns to the non-highlighted state when the pump is off.
9.Press the ‘Dig Outs’ button to access the Digital Output screen.
10.With the H-O-A switches off, press each of the DO buttons and verify that the correct relay changes state while
the button is pressed. Relays that are off will turn on and relays that are on will turn off when the button is
pushed.
11.For each pump, turn the H-O-A switch to the ‘Auto’ position and press the corresponding DO button. Verify
that the correct pump runs. Repeat for all pumps.
12.Press ‘F1’ until the System Setup Menu is displayed.
Setpoint Entry
1.Select the ‘Setpoint Config’ button.
2.Enter the Low Pressure setpoint. When the header pressure falls below this level, another pump will be started.
