A. Introduction
Thank you for purchasing DIG’s LEIT-2 controller, which operates as part of the
LEIT-2 system. This manual describes how to get the LEIT-2 controller up and
running quickly. After reading this manual and having been familiarized with
the basic functionality of the controller, the manual can be used as a reference
for less common tasks in the future.
B. About the LEIT-2 System
The LEIT-2 ambient light (solar) powered irrigation controller is an advanced
wireless device that is programmed using the LEIT RC2 remote handset. The
LEIT-2 controller is comprised of a photovoltaic module (PVM panel), 2 pairs
of 18” (45 cm) station wires used to connect the controller with up to two
S-305DC solenoids, plus a pair of yellow wires for a sensor connection. The
LEIT-2 has an ultra-compact photovoltaic module that harnesses light energy
to generate electricity that is stored and used to power the controller day and
night in any kind of weather. The LEIT-2 controller is operated using the LEIT
RC2 remote control handset, which has an operating range via a 2-way radio
of up to 350 ft (100 m) line of sight.
The LEIT-2 controller requires daily exposure to light levels at a minimum of
3000 lux, which is equivalent to daylight around 7-8 AM on a cloudy day. On
very cloudy days the controller requires more time to charge up and to operate
with the radio.
IMPORTANT: Communication between the LEIT RC2 handset and the
LEIT-2 controllers are automatically limited to daylight hours when there is
sufficient light energy. Longer bright light days will enable the radio to operate
automatically over longer parts of the day, including through the night.

4. WATERPROOF WIRE CONNECTORS (not included).
1.4 Quick Installation Setup and Operation Review
In order to establish communication for the first time between a LEIT RC2
handset and LEIT-2 controller the following steps must be taken:
1. Charge the LEIT RC2 handset (see LEIT RC2 instruction).
2. Setup the LEIT RC2 handset (see LEIT RC2 instruction).
3. Install the LEIT-2 controller following the LEIT–2 installation instructions,
see Section 2, then set it out in the light for initial charge
a.
In bright light conditions (full sun) charging the controller will take under 30 min.
b. In shaded conditions charging the controller could take up to 2 hours.
c. Communication will only initiate when the controller is fully charged.
4. Follow the instructions steps of how to establish initial communication
between a LEIT-2 controller and LEIT RC2 handset.
STEP 1: Splice the two, yellow and yellow with black stripe sensor
wires together using waterproof connectors. This splice will distinguish
that the controller is ready to communicate with a LEIT RC2ET handset.
NOTE: Do not connect yellow wires together until after the
unit has charged and you are ready to assign the ID number.
STEP 2: Using the LEIT RC2 Handset, select Default Setup and
connect
to the LEIT-2 controller using Radio Uplink icon (see page 17).
STEP 3: After establishing communication between a LEIT RC2 handset
and a LEIT-2 controller, setup the controller selecting Setup icon found
in the Controller Menu. Then select Cont. Setup icon found in the Setup
Menu Screen (see RC2 handset operation instructions).

STEP 4: After setting up the controller, program the controller (See RC2
handset operating instruction).
The handset and controller should now be available for communication.
2. Installation
2.1 Solenoid and Valve Installation
NOTE: Maximum operating pressure is up to 150 PSI (10.5 BAR).
Use DIG’s 305DC-XXX 3/4” to 2” valves or Model S-305DC solenoid and select
the appropriate conversion adaptor for the valve(s) that will be used with the
S-305DC solenoid (see list 1.2, #4 on page 8).
1. Shut off the mainline to the valve.
2. Install the valve (model 305DC-XXX) or unscrew the conventional solenoid
from the valve installed and remove the solenoid housing, solenoid stem,
plunger, spring, and O-ring (if necessary).
3. Select the appropriate conversion adapters for the valve(s) (see list 1.2, #4
on page 8).
IMPORTANT:
Do not remove existing O-ring on BUCKNER and SUPERIOR
valves. When installing adaptor on BUCKNER and SUPERIOR valves remove
the adapter sleeve (model 30-424) before installing.
4. Thread and tighten the conversion adapter clockwise to the compatible
valve port. Do not over tighten (see A).
5. Screw model S-305DC solenoid into the selected adapter. Tighten the
solenoid by hand, but do not over tighten (see B).
6. After installation is complete, turn the water supply on and pressurize the
main line. The valves will open momentarily and then shut off. Test each
valve in manual operation by turning the solenoid counter clockwise a half
turn or until the valve opens, and clockwise to close (see C).
10

7. Splice the solenoid hot wires (red) to the controller’s incoming red station
wire with stripe (V1). Splice the solenoid white wire to the single incoming
white wire with stripe (V1). If needed, repeat for the second valve. USE 2
CONVENTIONAL DRY-SPLICE WATERPROOF CONNECTORS WITH
CRIMP SLEEVE. Leave slack on each side of the wires so that repairs can
be carried out easily.
NOTE: The solenoid operates only
with 2-way normally closed valves.
NOTE: Station one red and white controller
wires are identified by the black stripes.
IMPORTANT: If a valve remains open in manual operation, you may need to
examine the solenoid and the solenoid adaptor to see that they are installed
correctly and the adaptor is firmly secured. Do not over tighten the solenoid
to the adapter and to the valve and do not cross thread the adaptor into the
solenoid cavity.
CAUTION: For all valves with built-in internal manual bleed lever, make
sure the lever is in closed position. Do not move the lever after installing the
solenoid with the valve adapter. If the manual lever on the valve is used, it can
damage the adapter or the sleeve causing the valve to stay open.

Option B: Mounting Column (model 30-831)
1. Excavate a trench from the valve to the column location and then, pull a
set of colored wires from the valve area to the mounting column location
(one pair for each valve). Each pair should consist of one white wire, and
one red or colored wire, preferably of differing colors. Each pair should be
taped and marked separately at both ends, so that the wires do not get
cross-connected (see ).
2. Insert the pairs of wires through the bottom of the mounting column and
push the wires up through the column until at least 6”
(15 cm) of wire
extends from the top of the mounting column (see ).
3. Install the mounting column, setting the curved bottom of the mounting
column in an 8” x 8” x 6” (20 x 20 x 15 cm) frame and pour in the 90 lb
(40 kg) sack of cement (see detailed illustration). Make sure the column is
vertical and the opening in the curved bottom is accessible and unclogged

5. Troubleshooting
The LEIT-2 wireless irrigation control system is a series of components
consisting of LEIT-2 ambient light powered 2 station controller, the RC2
handset, S-305DC solenoids, solenoid adapters, hydraulic control valves, and
wires/splices. It is best to troubleshoot this DC system (like an AC system)
by a process of elimination; the goal being to determine which component(s)
has failed. The following facts and tips may be helpful to eliminate certain
components and facilitate faster troubleshooting. It is assumed that these
are installed controllers that are receiving the proper amount of light. Keep in
mind that the problem may be with more than one component.
5.1 Troubleshooting Controller
1. To test the controller’s output, connect a solenoid to one of the controller’s
19

red and white wire pairs. Institute a test run via the handset with 1 minute
on the station in question and zero minutes on the other station. If the
solenoid is not installed, verify that the plunger retracts and extends or
that you hear the sound of the plunger latching. If the solenoid is installed
onto a valve, see that the valve turns on and the sprinklers or drip system
is working. If it does not turn on, the plunger does not retract and extend
or no sound is heard of the plunger latching, repeat the process using a
second solenoid. If the problem continues you may have an issue with the
controller wires and the WATERPROOF CONNECTORS.
2.
The LEIT-2 controllers function only with S-305DC solenoids or 305DC-XXX
valves.
3. The LEIT-2 controllers function only with compatible normally closed
sensors (HUNTER MINI-CLICK or RAIN BIRD RSD).
5.2 Troubleshooting Solenoids
1. Verify that the correct solenoid and adapters are being used for the valve in
question.
2. Verify that the white and red wires from the solenoid are connected to the
white and red wire pair on the controller and that these splices are tight,
and corrosion free.
3. Verify that no water is leaking externally near the adapter, stem, or bonnet.
4. Verify that all O-rings and/or rubber hoses are in place, if in doubt, check
the adaptor and the solenoid.
a. To test S-305DC solenoid, remove the solenoid from the valve and
disconnect the hot and common wires. Verify the solenoid functions
properly using a 9-volt battery by briefly touching the wires to the
positive and negative contacts. Reverse polarity if nothing happens.
Plunger should retract. Reverse polarity to close, (plunger should extend
and a sound of the plunger latching should be heard).
b. If the solenoid does not function with a 9-volt battery, check the battery.
If the problem with the solenoid continues after using a second battery,
it should be replaced.
