SOLENOID CONTROL OPTION
PROVIDED BY LEONARD VALVE
Description:
The Solenoid Control Option (SCO) is designed to accept dry contact inputs, either Normally Open
(N.O.) or Normally Closed (N.C.), in order to switch an AC powered solenoid opened or closed.
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 an AC powered solenoid in the event that
the alarm on the LMS-188-4P-BMS 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-BMS
will switch to N.C. and the solenoid will shut down.
Solenoid valve and associated power supply are to be
provided by others.
Installation:
Included with every SCO is a 12 VDC/600 mA power source with a 10’ lead that requires a dedicated 110 VAC
outlet to plug into. See wiring diagram below for reference. Do Not Energize SCO, LMS-188-4P-BMS, or
solenoid valve until wiring is complete.
Solenoid valve and associated power supply are to be provided by
others.
1.
Connections from the power source to the SCO (+ side to terminal
7
), terminal to
solid state relay (terminals
3+ to 8
), and power source to solid state relay (- side to terminal
4-
) have
been made at the factory.
2.
Properly ground the SCO by using the screw provided inside of the enclosure and
connect to suitable earth ground
3.
Connect terminal
5
(12VDC) to the
COMMON ‘C’
terminal (
9
) of the LMS-188-4P-
BMS relay switch.
4.
Connect either terminal
9 or 11
from the LMS-188-4P-BMS relay switch to terminal
6
on the terminal strip. Use terminal
9
with N.C. solenoids; use terminal
11
with N.O. solenoids.
5.
Connect the positive side of the solenoid power supply to terminal
1
on the solid state
relay.
6.
Connect terminal
2
on the sold state relay to the positive side of the solenoid valve.
Complete the circuit by connecting the neutral side of solenoid to the neutral side of power supply.
