a. introduction

Thank you for purchasing DIG LEIT® X or a XRC series controller.

This manual describes how to get the LEIT X or XRC 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.

Please take the time to read through the enclosed instructions and follow them step-by-step.

B. aBout the leit X & Xrc controller

The LEIT X and XRC Series Controllers are advanced ambient light powered water management irrigation

controllers. The LEIT X and XRC use a time tested photovoltaic module, which harnesses light energy to generate

electricity that is stored and used to power the controller day and night in any kind of weather.

DIG LEIT irrigation controllers are available in two models: LEIT X (without radio) or LEIT XRC (with radio remote

control capability).

The LEIT X and XRC series irrigation controllers have an improved menu base with straightforward programming

that allows for a wide range of irrigation programs. Features include four programs with three start times per

valve, manual runs with “skip to the next valve” option, rain delays for up to 99 days, budgeting up to 200 percent,

status checks, review history reports, modify program settings, valve grouping, verify solenoid integrity, radio

remote connection (XRC) and more.

Using the LEIT Link remote control handset in conjunction with a LEIT XRC controller, the user can review status

and history reports, modify program settings, temporarily interrupt a running program, do a manual run and test or

skip to the next valve mode from a distance of up to 800 feet line of site. The current running program and current

valve open information is provided when activated. In the Check Status mode the handset can review time, date,

budget, sensor activation and solenoid integrity. In Uplink History one can review the hourly usage of each valve by

month, or year, including Manual run usage. The LEIT Link handset is a 2-way radio device that can request or send

information and commands to a particular LEIT XRC controller and receive confirmation for the information sent or

requested.

IMPORTANT: The LEIT XRC requires greater energy for radio communication than is used for the

controller alone. The LEIT XRC controller requires daily exposure to light levels at a minimum of

10.000 lux, which is equivalent to daylight around 8-10 AM on a cloudy day. On very cloudy days the

controller requires more time to charge up and to operate with the radio. In order to retain sufficient

energy to maintain control over the valves, the controller radio will automatically turn off in low light

conditions. To maximize the energy available, the XRC controller should be installed in an open,

un-shaded area.

1. sysTem

This chapter will explain the components and installation of the LEIT X and XRC series controllers. The LEIT

controller must be installed according to the manufacturer’s recommendations; failure to do so will void the

manufacturer’s warranty. The LEIT X and XRC controllers can replace all SOLATROL and ALTEC 8000 controllers

and can be mounted on the same column as the ALTEC 8000 by removing the plastic sleeve from the mounting

column and mounting the new controller in its place. The LEIT X and XRC can operate with all of the old SOLATROL

and LEIT 8000 solenoids, such as LEMA 1500E, 1500-4 and 1500S. We recommend all new installations be done

using the 160HE series valves and 1600HE solenoid actuator.

1. Battery: 9-volt alkaline battery for the LEIT Key

2. Standard wire stripper

3. Flathead screwdriver (9/64” or smaller)

4. Concrete: approximately three 90 lb (40 kg) bags

5. Conventional waterproof wire connectors

2. InsTallaTIon

Select the optimum location for the LEIT X and XRC series controllers. If possible locate the controller in open area

not adjacent to a wall or building. We recommend installing a rain sensor with each controller with the use of

adapter model SKIT 8821-4.

2.1 Valve Installation Model 160HE-XXX (2-WAY)

Recommended version is a complete valve assembly including LEMA solenoid actuator with plastic in-line valve

(globe), sizes from 3/4” to 2”.

Maximum static operating pressure is up to 150 PSI.

1. Shut off mainline to the valve.

2. Install series 160HE-xxx valves with a solenoid actuator according to a valve standard

installation specification (see Figure A on page 7).

3. After installation is completed, turn the water supply on and pressurize the mainline. The

valves should open momentarily and then shut off. Test each valve in manual operation by

turning the solenoid from left to right to open and right to left to close the valve, making

sure that the valve is operating correctly. The valve should open momentarily and then shut off.

4. Splice the solenoid actuator hot wires (red) to one of the color-coded wires. Splice the solenoid actuator white

wire to the single incoming white (common) wire. Use 2 conventional dry-splice waterproof connectors. Leave

the wires slightly loose on each side so that repairs, if needed, can be carried out easily. Make sure not to

exceed the maximum run recommendation of wire distance (see page 7).

2.2 LEMA Solenoid Actuator Installation Model 1600HE (2-WAY)

Select the appropriate adapter for the valve(s) that will be used (see list on page 5). The LEMA solenoid actuator

operates only with 2-way normally closed valves.

Maximum static operating pressure is up to 150 PSI.

1. Shut off mainline to the valve.

2. Unscrew the conventional solenoid from the valve and remove the solenoid

housing, solenoid stem, plunger, spring, and “O” ring (if necessary). For BUCKNER

and SUPERIOR valves, do not remove the existing “O” ring.

3. Select the appropriate conversion adapters for this valve(s) then thread and

tighten the conversion adapter clockwise to the compatible valve port, do not over

tighten.

IMPORTANT: When installing adapter on BUCKNER and SUPERIOR valves

remove the adapter sleeve (model 30-424) before installing.

4. Screw the LEMA 1600HE into the correct adapter. Firmly tighten the solenoid by

hand, but do not over tighten.

5. Positioning the solenoid at a 40-45° angel towards the valve creates a manual lever; helpful

for manual on/off.

6. After installation is completed, 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

turning the solenoid from left to right to open and right to left to close the valve, making

sure that the valve is operating correctly. The valve should open momentarily and then shut

off. If the valve remains open in manual operation, examine the adapter and the sleeve to

see that it is installed correctly and the adapter is firmly secured. Do not over tighten the

LEMA solenoid actuator to the valve and do not cross thread the adapter into the solenoid

cavity.

NOTE: For all brand name valves with 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.

7. Splice the solenoid actuator hot wires (red) to one of the color-coded field wires. Splice the solenoid actuator

white wire to the incoming white (common) wire. Use 2 conventional dry-splice waterproof connectors. Leave

the wires slightly loose on each side so that repairs, if needed, can be carried out easily. Make sure not to

exceed the maximum run recommendation of the wire distance (see A1 below).

WARNING: The LEMA solenoid actuators must not be tested with any AC valve tester or DC tester

over 9-volts. If you do so, it will cause irreparable damage to the LEMA solenoid actuator and the

controller unit. Testing the solenoids with equipment rated higher then 9-volts will void the warranty.

2.3 Wire Installation and Distance

Run all direct burial wires along their respective trenches from each valve box to the controller location. Use

selection of color-coded direct burial wires to connect to each solenoid red (hot) wire. Use white (common) wire to

connect to the solenoid’s white (common) wire. Make sure to label each color-coded wire inside the irrigation box

with the designated station number.

MAXIMUM WIRE DISTANCE

Wire gauge recommendation LEMA 1500S SOLENOIDS LEMA 1600 HE SOLENOIDS

12 AWG (4 mm2) 2400 feet (700 m) 7,500 feet (2272 m)

2.4 Controller Installation

1. To install the mounting column, set the curved bottom of the mounting column in

a 12” x 18” x 12” (30 x 45 x 30 cm) frame and pour in the three 90 lb (40 kg) sacks

of cement (see Figure A). Make sure the column is vertical and the opening in the

curved bottom is accessible and unclogged. All wires should route to the controller

through the bottom of the mounting column (see A1).

NOTE: Make sure the cement pad is dry before continuing with the

installation

Part 1 Introduction

1.1 LEIT X, XR and XRC controllers are advanced water-management irrigation controllers. The controllers utilize ambient light as the source of energy to

operate up to 28 valves using a low voltage, high efﬁciency, watertight, 2-way magnetic solenoid actuator that operates at 5-volts. Built to the highest

quality standards (ISO 9002), the LEIT X, XR and XRC controllers have a menu base program with straightforward programming that allows for a wide

range of irrigation programs such as valve grouping, 4 programs with 3 start times, run times up to 6 hours, budget, rain delay, status reports, history

reports, manual runs and more. The controller design uses the most advanced time-tested photovoltaic module, which provides more power to harness

light energy day and night, anytime, anyplace. Used for sprinkler or drip systems, the LEIT X, XR and XRC controllers are commercial quality water

management controllers for any type of environment and for a wide range of uses.

2. Run the field wires along their respective trenches from the

valve box up to the bottom end of the mounting column.

Make sure not to exceed the maximum recommended wire

distance (see chart for maximum wire distance on page

xxxx). Push the wires up through the column until at least

12” (30 cm) of wire extends from the top of the mounting

column (see B1).

3. Remove the door from the LEIT controller using the door key

(included) and slide the controller into place on top of the

mounting column. Make sure that 12” (30 cm) of wires are

now inside the controller and cannot slip back down into the

column (see C1).

4. Insert the two clamp spacers and the two screws (both

included with the mounting column) into the holes

located on the lower left and right side of the controller.

Tighten the screws with the hex-key (included) until the

controller does not turn or twist and cannot be pulled off

of the mounting column (see D1).

5. Connect the station wires to the controller using a standard wire stripper.

Strip 3/10” of insulation from the tip of each of the station colored (labeled)

wires. Connect the color-coded (hot) wires into the connector strip labeled

with the station number and tighten the connector screw using a screwdriver.

Connect the white (common) wire into either of the two common wire

connectors labeled “common” located at the lower part of the connector strip

and tighten the connector screw using a screwdriver. If using a master valve,

connect the red (hot) wire from the master valve into the station labeled

“MV/P” (see Figure E1). For pump or other electrical equipment, see detailed

installations on page 10.

3. sensor InsTallaTIon

The SKIT switch-type, weatherproof sensor adapter provides a quick, reliable way to connect a compatible rain,

freeze, moisture or other normally closed, switch-type sensor. The connection can be made either directly to the

LEIT series irrigation controllers or to one of the micro-powered solenoid actuators.

3.1 Sensor connection to unused station

If there is an unused station on the LEIT controller, connect the sensor directly using a SKIT 8821-4.

a. 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 to the

sensor’s two normally closed (N/C) wires (see Figure B, Option 1). If possible, choose a solenoid location

close to the controller.

3.2 Sensor connection if station is not available:

If station is unavailable, or the controller is to 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 (see Figure

B, Option 2).

b. Choose a valve that is closest to the sensor location and, if possible, choose a sensor location close to

the controller. 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) wire and connect both onto the common field wire. Again, a 3-wire

connection should have been created. Finally, splice the two SKIT black wires to the sensor’s two

normally closed (N/C) wires.

3.3 Sensors compatible with LEIT controllers:

Rain sensors are the HUNTER MINI-CLICK II and the RAIN BIRD RSD.

Moisture sensors are the IRROMETER RA and TGA series.

Freeze sensor is the HUNTER FREEZE-CLICK.

4. pump or any eleCTrICal equIpmenT InsTallaTIon

If it is required to switch ON a pump, fertilizer injector, fountain or light, two connection options are available using

the RKIT 8810S relay interface module.

The RKIT 8810S units are used to switch 10 amp electrical circuits to a voltage up to 240V AC or 30V DC.

NOTE: RKIT 8810S can be used with LEIT Series 4000, X and XRC.

4.1 RKIT Installation to the MV/Pump Terminal

To operate all the valves with the unit connected to (e.g. pump), connect the RKIT to the MV/Pump terminal (see

Figure C).

4.2 RKIT Installation to One of the Valve Station Terminal Connectors

Operate only the valve number that RKIT has been installed to (e.g. Fountain will turn on/off by only the station

that is using the RKIT).

To install the RKIT, run a red (hot) wire from the RKIT to any of the controller station terminals. Then, run

a white (common) wire from the RKIT to the common terminal connector or if not available, splice it to the

common field wire using a waterproof connector. Run the two black wires from the RKIT to the AC/DC

equipment and connect them to the corresponding circuit to be switched (e.g. pump start relay).

Make sure to use waterproof dry-splice connectors for all connections.

NOTE: If the RKIT is connected to any circuit higher than 24-volts, it must be located in its own high

voltage junction box in accordance with local electrical code.

If a pump start relay coil current is greater than 2A (Model 8810S 2A up to August 2007) or 10A (Model 8810S 10A

after August 2007) use a pilot relay.

WARNING: RKIT cannot be housed in the same box with any low voltage equipment.

Do not connect the RKIT to a circuit higher than 380-volts.
