In order for the LectroCount LCR 600 to control valves
with solenoids on 110VAC 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: +12VDC
Materials needed for wiring valves with 110vaC
solenoids: not supplied with the valve
• SPST relay switch (1 per solenoid)
•
20AWG stranded wire (2 per solenoid)
• Weatherproof flexible conduit, ½" diameter and ½"
NPT conduit connectors or cable glands (if application
requires)
• PTFE tape or pipe sealant
To wire 110vaC solenoids to the lCr 600:
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.
Turn off all 110VAC circuits before beginning
the installation.
