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 (labeled #V1 and #V2) used to connect the controller
with up to two S-305DC solenoids, plus a pair of yellow wires for 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.

7. After installation is complete, turn the water supply on and pressurize the
mainline. The valves will open momentarily and then shut off. Test each
valve in manual operation by moving the manual handle from left to right to
open and right to left to close the valve, making sure that the valve is
operating correctly.
8. Splice the solenoid hot wires (red) to the controller incoming station wire
(V1 red). Splice the solenoid white wire to the single incoming white wire
(V1). If needed repeat for the second valve. Use 2 conventional dry-splice
waterproof connectors. 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: V1 may be identified by label or striped wires.
IMPORTANT: If a valve remains open in manual operation, you may need to
examine the solenoid adaptor and sleeve to see that they are installed
correctly and the adaptor is firmly secured. Do not over tighten the solenoid 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.

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 valve-assembly 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 valve assembly (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 above in
1.2 #4 on pages 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 (no tools necessary) (see a).
5. Make sure that the solenoid holder/handle is not inserted onto the solenoid
housing and then, screw model S-305DC solenoid into the selected adapter.
Firmly tighten the solenoid by hand, but do not over tighten (see b).
6. Slip the manual handle into the solenoid housing. Positioning the solenoid
handle at a 40-45° angle towards the valve creates a manual lever; helpful
for manual on/off (see b1-c).

5. There are 6 wires or three sets of wires from the controller, 1 pair for each
valve and 1 pair for sensor connection (labeled V-1, V-2 and S). Connect the
controller’s output station wire (V1 red) to the hot wires (red) on the
solenoid. Then connect the controller’s output station common wire (V1
white) to the white wire on the solenoid using conventional dry-splice
waterproof connectors. Repeat the same steps for station 2. Leave slack in
the wires on each side so repairs can be carried out easily (see 6).
NOTE: V1 may be identified by label or striped wires.
6. Reattach the valve box cover on top of the valve box and if available lock
the cover to the box (recommended) (see 6).

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
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 will only function with S-305DC solenoid or 305DC-
XXX valve
3. The LEIT-2 controllers will only function with compatible 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.
5. If the valve is weeping or not closing completely, the adapter being used
with the S-305DC solenoid may be loose, cross-threaded, missing an “O”
ring, the adaptor sleeve could be damaged, or the valve diaphragm inside
the valve could be in need of cleaning or replacement.
