SKIT 8821-4
Installation Manual
INTRODUCTION
The SKIT switch-type, weatherproof sensor adapter provides a quick, reliable
way to connect compatible rain, freeze, moisture, or other normally closed
switch-type sensors. The connection can be made either directly to the LEIT
series irrigation controllers or to one of the micropowered solenoid
actuators.
FEATURES:
- Waterproof construction
- Easy to install
- Adapts to a wide range of sensors
SPECIFICATIONS:
- Compatible with normally closed switch-type sensors only
- Includes four 12-inch 14-gauge wire leads
- Length: approx 1.25″ (3.1 cm); Diameter: approx 0.75″ (1.9 cm)
INSTALLATION
Normally closed switch-type sensors (such as rain, moisture, or freeze sensors) can be installed on a LEIT Controller if there is an unused station available. If a spare station does not exist, a sensor can be installed at one of the valve locations by connecting a SKIT 8821-4 to any LEMA actuator. For either type of installation, a SKIT 8821-4 is required to connect a sensor to the system.
SENSOR CONNECTION TO UNUSED STATION
If there is an unused station on the LEIT controller, connect the sensor
directly to it using a SKIT 8821-4.
PROCEDURE: Run a red (hot) wire from the unused station connector position on
the LEIT controller to the red (hot) wire on the SKIT 8821-4. Then run a white
(common) wire from the common connector station position on the LEIT
controller to the white (common) wire on the SKIT. Finally, splice the two
SKIT black wires into the sensor’s two normally closed (N/C) wires.
SENSOR CONNECTION IF STATION IS NOT AVAILABLE
If the station is unavailable, or the controller is too far from the sensor,
connect the SKIT 8821-4 to LEMA actuators at a valve closest to the desired
sensor location. This method can be used to minimize excessive wire runs.
PROCEDURE:
Choose a valve that is closest to the sensor location. On the installed LEMA
series actuator, splice the red (hot) wire to the SKIT’s red (hot) wire AND to
the red (hot) field wire creating a 3-wire connection. Next, splice the LEMA’s
white (common) wire to the SKIT’s white (common) and connect both onto the
common field wire. Again, a 3-wire connection should have been created.
Finally, splice the two SKIT black wires into the sensor’s two normally closed
(N/C) wires.
NOTE: For use with LEIT 4000, X, and XRC controllers only. Do not use
LEIT-2 or LEIT-2ET systems.
