Installations

When ordered as part of a meter system with a LCR

600, Liquid Control’s optical air and vapor eliminators

are bolted onto the strainer and wired to the LCR 600

at the factory. Optical air and vapor eliminators can

also be ordered separately and installed onto meter

systems already in service. For mechanical installation

instructions, refer to the manual specific to the optical

air and vapor eliminator. Instructions for wiring optical air

and vapor eliminators to the LCR 600 are provided on

this page.

Materials needed for wiring valves:

not supplied

with the air or vapor eliminator

20AWG stranded wire (2 for the S3 solenoid valve)

Weatherproof flexible conduit, ½" diameter and ½" NPT

conduit connectors or cable glands

PTFE tape or pipe sealant

To wire optical air and vapor eliminators to the

lCr 600:

1. Attach cable glands and/or conduit connectors to the S3

solenoid valve, the optical sensor, and the LCR ports.

2. Thread the 20AWG wires through a piece of weatherproof

conduit cut-to-length from the S3 solenoid to a LCR 600

port.

3. Run the weatherproof conduit between the S3 solenoid-

operated valve and the LCR 600 housing. Pull the wires

through the ports, and tighten the connectors. Liquid

Controls recommends running the optical sensor wire

through weatherproof conduit as well.

4. Connect the three 20AWG wires to the S3 solenoid-

operated valve terminals and to terminals 52 and 53 on

the J15 terminal block of the LCR 600 CPU board.

5. Connect the optical sensor wires to terminals 54, 55, and

56 on the J15 terminal block of the LCR 600 CPU board.

Disconnect the power before working on the CPU board.
