MOUNTING AND INSTALLATION
CONTROLLER PLACEMENT
WARNING: Do not drill holes in the controller's case. It has all the holes necessary
for mounting it on a wall or pedestal. Drilling holes in the unit will cause metal
chips to mix with the electronics and this will cause the unit to malfunction. If, for
some reason, it is absolutely necessary to drill additional holes in the unit, carefully
remove all the electronics prior to doing so.
Controllers are suitable for indoor/outdoor environment. It is lockable, dust-free and rain
resistant. Outdoors the controller should be placed in a shaded and dry environment not
subject to direct sprinkler spray or continuous heavy moisture. Additionally, a pedestal
(PED 1) is available for outdoor controllers; contact your Rain Master distributor.
MOUNTING THE CONTROLLER
1. On an upright, flat and secure surface, place the mounting bracket at eye level and
fasten securely.
2. Mate the bracket on the back of the controller to the mounted bracket and hang the
controller.
3. Secure the bottom of the controller by placing a screw through the hole located in its
back wall at bottom center.
CONTROLLER CONNECTIONS – AC POWER
1. Refer to Figure 1 - Power and Field Wiring.
2. Mount controller.
3. Place Rain Switch in “No Watering” position.
4. Remove lower panel.
5. Using #10-gauge or heavier copper wire, connect ground screw to ground rod or
grounded water pipe using a ground rod clamp. The wire should be as short as possible
with no sharp bends or kinks. If multiple clocks are being installed in the same
location, use a ground rod for each and contact the factory for the RMIS pamphlet
on proper grounding techniques.

ELECTRICAL GROUNDING FOR THE CONTROLLER
Proper electrical grounding is required to ensure safety to you, as well as to protect the
controller electronics in the event of electrical line surges or lightning. In areas where
lightning is a common occurrence, it is strongly recommended to use the HAWK model
HK-T.
Grounding Instructions
1. Mount the controller as close as possible to the grounding rod, so that the #10 grounding
wire from the controller to the ground rod is as short as possible. Ensure the grounding
wire is free of nicks and bends.
2. Use a grounding rod clamp to secure grounding wire to grounding rod. Be sure all
surfaces are clean of oxides and dirt, and that all connections are solid and secure.
3. In areas of very dry soil or sand, it may be necessary to "Dope" the grounding rod.
Contact your Rain Master distributor or Rain Master for grounding pamphlet,
“RMIS Grounding”.
4. Should the 8' grounding rod not penetrate completely into the soil it is acceptable to
put it into the ground on a slight angle. It is important that the rod be a full 8' into
the ground, with only enough of the rod showing to clamp the wire on. Should other
grounding installation requirements be necessary, contact your distributor or Rain Master.
Note: It is important to check the resistance periodically to ensure it is not greater than
10 ohms. Contact your Rain Master Distributor for details.

CONTROLLER CONNECTIONS – VALVES AND FIELD WIRING
The controller utilizes quick disconnects and color coded wires. The wires are 24" long
and each end must be stripped and attached to the corresponding field wire. HAWK HK
and HK-T model controllers come equipped with terminals to which the field wires are
directly connected. Unused wires should be taped off to prevent shorting.
The station numbers are labeled just above the quick disconnects behind the lower panel
of the controller. Simply match the station's wire to the appropriate field wire. Note that
the controller's COMMON wire isWHITE and the MASTER VALVE/PUMP is BLACK.
Should it be necessary to detach the Quick Disconnect blocks from the printed circuit
board, hold the plastic assembly and pull down gently but firmly.
Note: When reattaching the Quick Disconnect, be careful to make sure that the lip at the
top of the plastic connector is facing you as you push the connector onto the pins.
Additionally, be sure to match the Quick Disconnect blocks with the corresponding
color as labeled on the bottom of the printed circuit board.
MASTER VALVE AND PUMP WIRING OPTIONS
The RME HAWK provides a variety of control options when selecting a MasterValve
and Pump. Because the pump and master valve can be assigned to any program, and the
master valve can be either a Normally Open or Normally Closed configuration, virtually
any system can be accommodated. For example, drip programs may be SETUP in one
or more programs which don’t use the pump, while large rotors may be in a pump defined
program.The following table summarizes the options which are available, the installation
diagrams required to achieve these options, and the corresponding SETUP (programming
of the RME HAWK using the SETUP key). For detailed information on SETUP, please
refer to ADVANCED SETUP PROGRAMMING beginning on page 47.

ELECTRICAL CONNECTIONS FOR A MASTER VALVE
The RME HAWK allows you to SETUP the Master Valve (MV) output as either a
Normally Open or Normally closed configuration. When used in the Normally Closed
mode, the MasterValve line is a source of 24 VAC power. It is active whenever any station
in the controller is on. For Normally Open Master Valves, the controller supplies 24 VAC
only when either a Main Line Fault or Unscheduled Flow Fault occurs.
Normally Closed MasterValve Operation
If you have a Master Valve which requires activation to open, and no pump, connect the master
valve solenoid to the MV andValve Common terminals as shown in Figure 2. If more than
one clock is going to control the MasterValve, the clocks must be isolated from each other.
Contact RMIS for the pamphlet on multiple clock installations. During SETUP, select the
NC (Normally Closed) Valve type for all programs (1, 2, 3, 4).

Simultaneous Normally Closed Master Valve and Pump Operation
If you have a Master Valve which requires activation to open, and a pump which is always
needed whenever irrigating, connect BOTH the master valve solenoid and pump starter to
the MV and Valve Common terminals as shown in Figure 3. If the pump starter operates on
24 volts AC and the combination of the Master Valve Solenoid and Pump Starter require more
than 1 amp, you will need an isolation relay (Rain Master part: RLY1 or equivalent) and an
additional source of 24 VAC (see Figure 4). During setup, select the NC Valve type for all
programs which require the Master Valve and Pump. DO NOT select pump operation.
If the pump starter requires 120VAC, you will also need an isolation relay (RLY1).
If more than one clock is going to control the Master Valve and pump, the clocks must be
isolated from each other. Contact RMIS for the pamphlet on multiple clock installations.

Normally Open MasterValve and Pump Operation
If you have a Master Valve which is always open until energized and a pump, connect the
solenoid to the MV and Valve Common terminals and the Pump to Station 1 as shown in
Figure 5. During setup, select valve type NO (Normally Open).The Master Valve will only
be activated when the controller detects a Main Line Break or Unscheduled Flow condition.
In this case, a fault condition will exist until manually cleared. Also during SETUP, assign
which programs (1-4) require the pump to operate.
FLOW SENSOR INSTALLATION
Refer to Figure 6. Install the Flow Sensor in the Main Line as shown, making sure that
there are at least 10 pipe diameters upstream and 5 pipe diameters downstream of the
sensor from any valve, reducer, elbow, or other obstruction or device which may cause
turbulence in the water flow. Observe the proper direction of flow according to the flow
arrow on the sensor. Install a valve box around the sensor and make the electrical connections
inside the box. Use waterproof nuts over the splices.
The use of Rain Master EV-CAB-SEN or other shielded cable is required to ensure proper
operation. Polarity must be observed when connecting the sensor to the controller.

TAPPING WIRES TO LOCATE VALVES IN THE FIELD
DON'T – Do not turn a station on and tap a wire to the controller's station
terminal/wire to see what valve in the field is connected to it. This is damaging to
both mechanical and solid state controllers and will cause the controller to go into a field
wire fault detection mode. The simple method shown below is safe and will work for
both types of controllers.
1. Use Manual Station to turn on Station 1, perhaps for 1 hour.
2. Flip the Rain Switch to the “No Watering” position.
3. Touch the wire from the unknown field valve to the controller's Station 1 terminal/wire.
4. Flip the Rain Switch to the “AutomaticWatering” position and the valve on that wire
will be activated.
5. When you know what valve it is, flip the Rain Switch off before removing the field
wire from the controller's station terminal/wire.
6. Choose the next field wire and start the process over at Step 2.
7. When all done, turn off Station 1.

REMOTE CONTROL CAPABILITY
All Rain Master controllers feature patented built-in remote control capability which
allows you to operate the controller for a distance of 1 mile in congested areas via a hand
held transmitter. (Consult the Remote Manual for operating instructions).
Never connect anything but a Rain Master remote control receiver to the controller's front
panel remote control connector or damage will result. Connecting to any other remote
control device to any portion of the Rain Master controller will void all warranties and
may cause damage.
ELECTRICAL SPECIFICATIONS
Input power required : 105-130 VAC, 50/60 Hz, .5 amp maximum, .1 Amp idle
Output power: 24 VAC, 1.5 Amps maximum total output
or 36 VA maximum total output
1 Amp per station of Master Valve
Solenoids are rated in either Amps or VA.The term VA stands for Volt-Amps, which is
obtained by multiplying the Amps required by the operating voltage, 24 VAC.
Most modern solenoids require approximately .25 Amps, which is equivalent to 6 VA.
This means that up to six solenoids can be energized at the same time. If you are using a
Master Valve and separate pump, for example, you may use the NO STACK option in
SETUP and run all four programs simultaneously.
Example:
Four programs (.25 A times 4) 1.00 Amps
Master Valve (.25 A times 1) .25 Amps
Pump using Rain Master RLY1 (.20 Amps) .20 Amps
Total Current 1.45 Amps
This does not exceed the maximum allowable 1.5 Amp controller limit.
If higher current solenoids are used or if more than one solenoid is connected to one
station output, caution should be used when operating in NO STACK mode.
