If you install the valve yourself, refer to the valve installation and operation manual for mechanical installation. Instructions for wiring Liquid Controls valves to the LCR-II can be found below.

 

Materials needed for wiring valves

These materials are necessary, but are not supplied with the valve:

 

•20 AWG stranded wire–3 per solenoid. Unnecessary for 3-way solenoid valves. Only 2 are necessary for E7 solenoids.

•Weatherproof flexible conduit, ½" diameter.

•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.

 

 

 

 

Valves with 110VA C Solenoids

In order for the LectroCount LCR-II to control valves with solenoids on 110 VAC circuits, you must install a relay switch on the positive leg of the solenoid’s circuit.

 

Relay switch specifications:

•Switch: SPST (single pole, single throw)

•Switch Position: Normally open

•Contact Rating: Greater than maximum current of solenoid

•Voltage: +12 VDC

 

Materials needed for wiring valves with 110 VAC solenoids

These materials are necessary, but are not supplied with the valve:

•SPST relay switch (1 per solenoid)

•20 AWG stranded wire (2 per solenoid)

•Weatherproof flexible conduit, ½" diameter and ½" NPT conduit connectors or cable glands

•PTFE tape or pipe sealant

 

To wire 110 VA C solenoids to the LCR-II:

1.Turn off all 100 VAC circuits before beginning the installation.

2.Install the specified relay switch(es) onto one leg of the 110 solenoid power supply circuit.

3.Connect the relay switch on the S1 power supply circuit to terminals 15 and 16 on block J13.

4.Connect the relay switch on the S2 power supply circuit to terminals 17 and 18 on block J13.
