valve Installation
If installing the valve yourself, please refer to the valve’s
installation and operation manual for mechanical
installation. Instructions for wiring Liquid Controls valves
to the LCR-II are on the following two pages.
Materials needed for wiring valves: not supplied
with the valve
• 20 AWG stranded wire (3 per solenoid). Not necessary for
3-Way solenoid valves. Only 2 needed for E7 solenoids.
• Weatherproof flexible conduit, ½" diameter and ½" NPT
conduit connectors or cable glands
• PTFE tape or pipe sealant
To wire valves to the lCr-II:
1. Attach cable glands and/or conduit connectors to the
solenoid valve(s) and the LCR-II port(s).
2. Thread the wires through piece of weatherproof conduit
that is cut-to-length from the solenoid to a LCR-II port.
3. Run the weatherproof conduit between the solenoid-
operated valve(s) and the LCR-II housing, pull the wires
through the ports, and tighten the connectors.
4. Connect the S1 solenoid-operated valve wires to
terminals 14 and 15 on the j13 terminal block of the LCR-
II CPU board.
5. Connect the S2 solenoid-operated valve wires to
terminals 17 and 18 on the j13 terminal block of the LCR-
II CPU board.
To wire a single stage valves for presetting:
1. Wire the S1 solenoid as instructed above.
2. Run a jumper wire from Terminal 15 to Terminal 18.
Disconnect the power before working on the CPU board.
Disconnect Power
Solenoid operated valve 81527 (3-way LPG solenoid)
has 3 cables potted into the housing. All other
solenoid operated valves on Liquid Controls valves
use cable assembly 81859, which has 2 cables.
Solenoid Operated Valve Cables
The Earth grounds for Terminals 16 & 19 are optional.
The solenoid operated valves are grounded through
the component they are mounted on.
