DC POWERED SOLENOID CONTROL
HARDWARE SUPPLIED BY OTHERS
Description:
This solution is for systems that utilize a DC powered solenoid valve and want to make use of the SPDT relay
switch included with LMS-188-4P-SM.
Solenoid valve and associated power supply are to be provided by
others.
Application:
The primary application is in systems where it is desirable to control a DC powered solenoid in the event that
the alarm on the LMS-188-4P-SM is active. When in non-alarm condition the relay is in a N.O. state and the
solenoid will allow water to flow through it freely. Once the alarm is active, the relay on the LMS-188-4P-SM
will switch to N.C. and the solenoid will shut down.
Solenoid valve and associated power supply are to be
provided by others.
Installation:
Solenoid power supply is to be supplied by others and is not available from Leonard Valve. The relay contacts
are rated up to 30 V/1A. See wiring diagram below for reference. Do Not Energize LMS-188-4P-SM or
solenoid valve until wiring is complete.
Solenoid valve and associated power supply are to be provided by
others.
1.
Connect positive side of power supply to the
COMMON
terminal (
2
).
2.
Connect either terminal
1 or 3
from LMS-188-4P-SM relay switch to positive side of DC solenoid. Use
terminal
1
with N.C. solenoids; use terminal
3
with N.O. solenoids.
3.
Connect neutral side of power supply directly to neutral side of DC solenoid.
