Connecting an IntelliFlo
®
Pump to the System COM Port
(see Illustration on page 20)
The RS-232 communication cable (provide with IntellliFlo pump) consists of a 50 ft 22 AWG four
conductor low voltage cable. The EasyTouch PL4/PSL4 Control Systems filter pump output is
rated at 120 VAC, 15 AMP maximum. Check the electrical rating marked on the pump motor before
connecting it to the system.
To connect the IntelliFlo pump communication cable to the Power Center:
1.
Switch OFF power Power Center at the main house circuit breakers.
2. Run the communication cable from the pump to the enclosure.
3. Insert the cable conductors into the one of the plastic grommet fittings, located on the
lower left side of the enclosure and pull the cable up through the low voltage to the PL4/
EasyTouch PL4/PSL4 Control Systems circuit board. See illustration on page 19.
4. Strip back the outer jacket four (4) inches. Strip back each conductor a ¼-inch.
5. Insert the conductors into the COM Port
(J20)
screw terminals located on the top of the
EasyTouch PL4/PSL4 Control Systems circuit board (see illustration below and page 31).
Secure the conductors with the screws. For wiring details, refer to the pin configuration
shown below. Note: Multiple conductors may be inserted into a single screw terminal.
