Introduction

Welcome to Rain Bird

Thank you for purchasing your new, state-of-the-art Rain Bird® Controller. For more than six decades, Rain Bird® has led the irrigation industry in meeting all of your water management needs by providing the highest quality products and services available. Your new Rain Bird® Controller is designed to give you a lifetime of on-site watering control.

The MDC Controllers

The MDC line of controllers are systems that completely manage your landscape and turf needs by letting you control all your irrigation functions from one central location. MDC Controllers use Schedules to control the days, times and length of time each valve operates.

Once you program and store irrigation Schedules and other instructions, the MDC communicates this information, through a two-wire (MAXI cable) communication path, to numerous decoders located throughout the irrigation system. The decoders act on command from the controller, activating solenoids on various valves, master valves and pumps.

The MDC2 Controller uses a program module, which supports up to 50 (decoder) outputs. The controller also has slots to hold three expansion modules. Each expansion module supports an additional 50 outputs. This means you can configure your MDC2 Controller to support 50, 100, 150 and 200 outputs.

Installation

This chapter of the manual explains how to mount your new MDC2 Controller on the wall, how to connect the wiring, install program and expansion modules and replace the battery.

Mounting the Controller

Before You Begin

Warning! Before installing your controller, make sure that the area around you is free from dirt and dust and that your hands and arms are clean. This will avoid contaminating the controller’s internal parts.

Warning! Do not let water or other liquids come in contact with any part inside the cabinet.

Choosing a location

When choosing the best location to install your wall-mounted controller, please consider the following:

You must install this controller in compliance with local electrical codes.

4 The MDC2 Controller cabinet is water-resistant, so you can mount it inside or outside.

4 Select an area, protected from vandalism, where the user can easily reach the controller. Rain Bird®

recommends placing the controller at eye level, in a utility room.

Warning! To minimize electromagnetic interference, select a location that is at least 15’ (4.6 m) away from high-draw motors, such as air conditioners, refrigerators or pool pumps.

4 Select a location that has access to 120-Volt AC electrical power (or the proper electrical supply voltage outside

the United States).

4 Mount the controller on a flat, stable, vertical surface. Allow sufficient conduit clearance for the electrical

connections at the bottom of the cabinet.

4 Allow 9 1/2” (24.2 cm) minimum clearance for the hinged cabinet door to swing fully to the left.

4 Allow at least 6 1/4” (17.2 cm) minimum clearance above the cabinet door so you can easily remove the hinge

pin to service the controller.

Installation, continued

Preparing the Controller Cabinet for the Power and Field Wires

Note: You can remove four knockouts from the

controller cabinet making it easy to route the wires. You will find two of these knockouts on the back (for routing wires through a wall) and two on the underside (for feeding wires through the cabinet’s bottom).

To tap out a knockout, place the cabinet on a firm surface with the groove facing you. Work your way around the groove with a slotted screwdriver, firmly tapping out the knockout.

A hole on the underside of the cabinet fits a 1” (2.6 cm) PVC male adapter for installing PVC conduit. You can increase its size to 1 1/4” (3.2 cm) by tapping out the knockout around the hole. If you are using #14 AWG wire, or larger, you may need the larger hole. If you run the wires through the bottom holes, you will need to install conduits. Slip the conduit through the hole and secure it with a male adapter or other conduit fittings.

Mounting the Controller on the Wall

Note: The MDC2 Controller has four mounting holes

on the back on the cabinet—three keyhole slots near the top and one circular hole at the bottom.

Note: To install the controller on a flat wall surface, use the left and right keyhole slots at the top of the cabinet. To install the controller on a narrow stud, use the center keyhole slot.

1. Place the mounting template onto your mounting surface. Make sure it is level and mark the top drill holes. If mounting to a stud, mark the drill hole in the center of the stud.

2. Drill the holes and use the appropriate plugs or fasteners.

3. Screw in the appropriate mounting screws, leaving about 3/8” between the screw heads and wall.

Note: The mounting materials and specific screws you need will vary according to the mounting surface (i.e., wood, cement, masonry, drywall, etc.)

4. Slide the MDC cabinet over the top screws.

5. If mounting to a stud, swing open the cabinet door and faceplate. Mark the position of the bottom drill hole and then lift off the controller. Do not attempt to drill the bottom hole through the cabinet.

6. Drill the bottom hole and remount the cabinet.

7. Secure the bottom of the cabinet with a screw, tightening it all the way.

There are three types of connections you must make to your MDC2 Controller. They include:

• ConnectingtotheTwo-wireCommunications

Cable,

• GroundingtheController,and

• ConnectingtotheMainPowerSource.

Note: You may also connect an optional sensor, which prevents irrigation during rainfall or when the soil is moist.

This section of the manual contains instructions for all three types of basic connections, and the optional sensor connection.

Note: If you are installing a field or sensor decoder, please see the MDC2 and Decoder Installation poster for more information.

All wiring must be installed and connected in accordance with local electrical codes.

Note: You can run wires through the holes at the bottom of the cabinet or through the knockout holes at the back of the cabinet. If you use the knockout holes, make sure you seal the unused bottom holes. If you run the wires through the bottom holes, you will need to install conduits. Slip the conduit through the hole and secure it with a male adapter or other conduit fittings.

Connecting to the Two-wire Communications Cable

Note: You can connect up to three separate

two-wire communications cables (paths). The communications cable you use must be approved for underground use. Rain Bird® recommends you use MAXI Cable, #14 AWG as your two-wire communications cable.

Warning! Do not install the communications cables in the same conduit as the wires to the Main power source.

To connect the cable,

1. Feed the two-wire communications cable through the conduit and into the controller.

2. Remove about 6” of the cable’s outer sheathing and strip about 5/8” of the insulation from the ends of the two wires.

3. Using a thin blade screwdriver, connect the wire ends to a set of L1 and L2 terminals. Tug on the wires to make sure the connections are tight.

Installation, continued

Grounding the Controller

The MDC2 Controller is equipped with built-in electrical surge protection. For this system to function, you must properly ground the controller.

Warning! Connect the controller to the grounding grid using at least a #8 AWG (10 mm) or #10 AWG (6 mm) bare wire. The wire should be as short and as straight as possible. You will void the warranty if you do not ground the controller to a maximum reading of five ohms.

To connect the ground wire,

1. Loosen the screw on the copper earth ground terminal and slide the end of the ground wire into the terminal. Tighten the screw to secure the wire.

2. Feed the ground wire through the same conduit you used for the communications cable and connect it to ground.

Connecting to the Main Power Source

The three Main power input wires for a standard 120-Volt AC transformer are black, white and green. You will find these wires in the high voltage compartment in the lower left corner of the controller cabinet.

To prevent electrical shock, make sure all supply power is OFF before connecting these wires. Electrical shock can cause severe injury or death.

All electrical connections and wiring runs must be made according to local electrical building codes.

To feed the power wires,

1. Locate the high voltage compartment cover, remove the screw and swing open the cover.

Installation, continued

2. Feed the Mains 120-Volt AC power wires into the high voltage compartment through a separate conduit.

Note: You can also connect the Mains 120-Volt AC power and transformer wires inside a junction box located outside the controller cabinet.

Feed the Mains 120-Volt AC power wires through the 1/4” knockout hole on the back of the cabinet. You also need to cut out the scored hole in the high voltage compartment’s fiberboard liner.

To connect to the Main power source,

1. Strip about 1/2” of the insulation off the ends of the power wires.

2. Using code-approved wire nuts, connect the black (HOT) wire to the black transformer wire, the white (neutral) wire to the white transformer wire and the green (ground) wire to the green transformer wire.

3. Tug on the connections to make sure they are tight, then close the high voltage compartment cover and replace the screw.

Installation, continued

Connecting an Optional Sensor

The MDC2 Controller allows you to connect an optional sensor. The controller works with any open or closed switch sensor.

Warning! The wires you use to connect the controller to the sensor must be approved for underground use. Rain Bird® recommends using a two-wire #18 AWG (maximum gauge) cable long enough to easily reach the controller.

Warning! Install the sensor wire in the same conduit you use for the two-wire communications cable and ground wire. The conduit for the power wires should only contain the power wires.

To connect the sensor’s wires to the controller,

1. Remove about 6” of the cable’s outer sheathing and strip about 5/8” of the insulation from the ends of the two wires.

2. Using wire nuts, connect the two-wire cable to the sensor wires inside a valve box.

3. Protect all underground splices with DBY connections. Insert the wire nuts into the DBY connectors and close the gap tightly. Place the connectors inside the valve box.

4. Run the two-wire cable leading from the sensor wires through a conduit and into the controller cabinet. Use the same conduit you used for the communications cable.

5. Using a thin blade screwdriver, connect the sensor cable wires to SENSOR terminal 1 and SENSOR terminal 2 inside the controller. Tug on the wires to make sure the connections are secure.

You have now completed mounting and wiring your new MDC2 Controller.

Installation, continued

Installing Program and Expansion Modules

The MDC2 Controller uses a program module that controls 50 (decoder) outputs. The controller also supports up to three expansion modules (MDC/M50D), each controlling an additional 50 outputs. So, by adding expansion modules, you can configure the MDC2 Controller to control 50, 100, 150, or 200 outputs. 200 is the maximum number of outputs the controller can manage in any combination over one, two or three separate two-wire communications lines.

Warning! When working with any program or expansion module, always use a grounding strap to avoid electrostatic discharge, which can damage the modules.

Warning! Always turn off the controller before you add or remove any module.

To add or replace a program or expansion module,

1. Use a Phillips head screwdriver to remove the two screws and lock washers holding the guide rail. Be careful not to lose the lock washers.

2. To remove a worn out module, grasp it by its tab and wiggle it back and forth while pulling up.

3. Hold the new module by its tab, so the back of the module faces the top of the cabinet.

4. Firmly plug a 10-pin expansion module into one of the three corresponding sockets on the circuit board. The program module is larger and fits

only in one socket.

Warning! When plugging a program or expansion module into an MDC socket, please note its orientation. Make sure the back of the module’s mini circuit board is facing the top of the cabinet and not the display screen. Plugging the modules in backwards will not damage the controller, but the controller will not work properly.

5. Once you install the modules, replace the guide rail.

Installation, continued

Replacing the Battery

The MDC2 Controller has a built-in lithium battery to backup and store the program memory. During normal use, the battery should last for 10 years. Replace the battery when the MDC2 Controller no longer holds the programmed information.

Warning! The components inside the MDC2 Controller are sensitive to electrostatic discharge. By using a grounding strap, you can help avoid electrostatic discharge, which can damage the units.

To replace the battery,

1. Remove the controller cabinet door from its hinges by opening the door, then pushing the metal pin up and out of the hinge. Set the door and pin aside.

2. Unscrew and remove the faceplate. Set the faceplate aside. Set the faceplate aside.

To prevent electrical shock, turn off the controller and shut OFF all supply power to the unit at the Main power before proceeding. Electrical shock can cause severe injury or death.

3. Using a Phillips head screwdriver, remove the five screws, lock washers and metal clip. Carefully lift the display and control module as far as the connecting wires allow.

4. Disconnect the two-wire harness from the board by grasping the connector and pulling straight up.

MDC

Installation, continued

5. Open the locking tabs on the three ribbon cables by pushing the tabs away from the cables. Disconnect the ribbon cables by grasping the wide sides of the connectors and gently pulling the connector away from the board. Set the module aside.

6. Using a thin blade screwdriver, gently pry the lithium battery out of its compartment and replace it with a new battery, positive side facing up.

Warning! Dispose of the depleted battery in accordance with local regulations.

If you mistreat the battery, it may explode. Do not recharge, disassemble or dispose of in fire.

To reassemble the controller,

1. Reconnect the three ribbon cables by firmly pushing each connector into their slots on the board. A small tab on the side of the connector slides into a slot on the socket, so each connector fits only one way. Firmly push to engage the locking tabs.

2. Plug in the two-wire harness into its corresponding slot on the board. It fits only one way.

3. Reposition the display and control module and replace the screws, lock washers and clip.

4. Replace the controller’s faceplate.

5. Screw on the faceplate.

6. Turn on the Main power supply to the controller and turn on the controller.

Note: When you change the battery, you will need to reprogram the MDC2 Controller.

Programming and Operation

Using the buttons on the controller, you can set up the MDC2 Controller to operate automatically. You can also run the controller manually without changing the Programs you have set.

This chapter shows you how to use the controller’s buttons and gives you step-by-step instructions for setting up the controller to suit your needs.

Familiarizing Yourself with the MDC2 Controller

Before beginning to program or operate your MDC2 Controller, take a moment to familiarize yourself with the controller. Note that the location of the ON/OFF switch is behind the removable panel. Once you turn the controller on, you can use the buttons to guide you through different display screens and functions on the (Liquid Crystal Display) LCD.

Most screens show a row of labels at the bottom. These labels indicate the specific function of the buttons under each label. As the labels change from one screen to the next, so does the function of the buttons. Labels with tabs contain submenus.

A backlight lights the display while you operate the buttons. Once you stop, the backlight remains on for about 70 seconds then turns off. The information is still on the display, but the display is not lit. Pressing any button turns the backlight on again.

Note: You must first turn on the backlight (press a button) before you can operate the controller.
