HOT SHOT OVERVIEW
ATTENTION: Depending upon the style of system that your are going to control with the Hot Shot
Wireless Controller you may need to supply additional parts. Such as relays, step-down transformers, Mur-
phy switches etc. These items are suggested in the wiring guides that follow in this manual.
HOW IT WORKS
Think of the HOT SHOT system as a 12-2 control wire going from the pivot to the irrigation pump. When the Hot
Shot Transmitter’s RELAY Input is activated, a 15 second delay timer is started. After the delay timer has expired,
the transmitter will send the (turn ON) command to the receiver. This transmission will close the relay contacts at
the pump to start water. When the pivot is done irrigating or when the safety is tripped, the pivot will open the Hot
Shot Transmitter’s RELAY Input contacts and send the (turn OFF) relay command to stop water. Battery backup
in the transmitter will still allow the HOT SHOT to work in case of a pivot power outage. Each system is coded
with its own four digit code so it will not interfere with other systems in the same area. The following manual has
been prepared to provide details for Transmitter installation and Receiver installation on electric and engine driven
wells.
MOUNTING
Cabinets are a weatherproof UV protected NEMA 4X cabinet with mounting ears on top and bottom. The Hot
Shot cabinet can be mounted on the side of a control panel, pole or any other surface as long as the antenna does
not have metal running within 12” of the antenna whip. If longer range is needed, an external long range antenna
can be used. Do not mount the HOT SHOT receiver to the well engine or cover because the strong vibrations can
be harmful to the unit.
CODE SWITCH SETTINGS
All transmitters and receivers will be shipped from the factory with preprogrammed field codes. This ensures
that your neighbor will not duplicate the same field code as your unit. Your field codes already match, so you do
not need to program any codes. If you ever need to replace a unit due to servicing, the field code can be pro-
grammed to match the existing or new add on units. FOLLOW THE EXAMPLE BELOW…

ATTENTION: All Hot Shot units have a designated GROUND Terminal. Hot Shot units must have
there ground terminal connected to a proper ground or grounding system as per the NEC (National Electri-
cal Code) and or your local and state electrical code guidelines.

INDICATOR LIGHTS
SUPERVISION FEATURE
The Supervision Feature is a great way for checking at a glance the
integrity of the system. The RED Supervision Light will come on
if the receiver has not heard it’s correct code from the transmitter
within the past three hours. Then the Supervision Light will begin
to blink until the receiver hears it’s correct code again. If there are
two or more receivers on the same transmitter and the Supervision
Light is blinking on both of them, it is indicating that the transmit-
ter is either turned off or malfunctioning. If only one out of the
two receiver’s Supervision Lights are blinking, it is indicating that
that receiver is malfunctioning and that the other receiver and
transmitter are working properly.
RECEIVER # SWITCHES(1,2,3,4)
When a Hot Shot Receiver (only 810-3R) is going to be used with A Hot Shot 810-3T transmitter using it’s #1,
#2, #3 or #4 SENSOR INPUTS, the receivers going to be used will need to be assigned to the sensor on the
transmitter that will control it. All receivers come factory set in the default mode as a #1 receiver. Meaning they
are only controlled by the SENSOR INPUT #1 of the transmitter. When using the SENSOR INPUT #2, #3 OR
#4 SENSOR INPUT the transmitter you will need to use the FOUR DIP SWITCHES located to the left of the
12-digit code bar on the receiver to program
the receiver so it can be controlled by it’s
designated SENSOR INPUT on the trans-
mitter. You can make it a #2 receiver
(which is controlled by the #2 sensor on the
transmitter) by only turning on the #2 dip-
switch. You can make it a #3 receiver
(which is controlled by the #3 sensor on the
transmitter) by only turning on the #3 dipswitch. This makes it capable for the pivot to control and share multi-
ple wells. Also see Discrete Operation and Multi Pivot Operation in the transmitter section.

STROBE Used for troubleshooting, this light flashes once for each of the four correct digits of the
code received. The light will stay on steady for one second if an incorrect digit of the
code is received. Example: If the light flashes two times and then goes on steady it is
indicating that the third digit doesn’t match. If the light flashes one time and goes on
steady it is indicating that the second digit doesn’t match. If the light comes on steady
right away it is indicating that the first digit doesn’t match.
RELAY When this light is on it indicates that its corresponding relay has been activated.
SUPERVISION When this light is flashing it indicates that it has not received its correct code
from the transmitter in the past 3hrs. Sliding function switch #8 to its OFF
position will turn off this indicator light.

TYPICAL HOT SHOT RECEIVERHOOKUP TO KILL AN
ENGINE DRIVEN WELL
RECEIVER UNIT 810-3R
HOT SHOT RECEIVERS NEED TO BE TURNED ON BEFORE THE HOT SHOT TRANSMITTERS
ARE TURNED ON. HOT SHOT TRANSMITTER ONLY TRANSMITT FOR 1 MINUTE. IF THE RE-
CEIVER IS TURNED ON AFTER THE TRANSMITTER IT WILL NOT OPERATE CORRECTLY
UNTIL THE TRANSMITTER IS SET TO TRANSMITT AGAIN.
AT THE ENGINE
DO NOT mount the HOT SHOT Receiver unit to the well engine or engine cover because strong vibra-
tions can be harmful to the unit.
The diagrams below show a simple way to control an engine driven well using a simple 117 or 518 Murphy kill
switch. Supply power to the receiver by hooking up the 12v positive input on the receiver to the 12v positive
terminal on the battery. Run a wire from the Negative input on the receiver to the negative terminal on the bat-
tery or to a good ground connection. Install a jumper wire connecting the negative terminal to the COM terminal
on the receiver. Connect a wire from the N.C. terminal on the Hot Shot receiver to the S or the SW1 terminal on
the Murphy kill switch. Then install a simple on-off (bypass) switch between the NC and the S or the SW1 ter-
minal. This bypass switch is needed because there will not yet be any water pressure at the pivot and the re-
ceiver’s COM and NC contacts will not open until the water is pressured up and the pivot is requesting water.
Now, with the switch opened, it will act as a bypass to let the engine start and get the water pressured up. Once
the water is pressured up and the pivot is set to request water the receiver’s green RELAY ON light will illumi-
nate and open the contacts. Now, the bypass switch can be closed so that when the pivot is finished and the re-
ceiver is sent a stop water signal, the receiver’s relay will close COM to NC. This shorts the Sterminal to ground
and kills the engine. Other variations and Murphy Kill switches will work as well.

ELECTRIC WELL HOOKUP
 Mount a 480v-120v step-down transformer to supply 120v to the receiver. The Hot Shot Re-
ceiver only requires 1 watt of power to operate. Hot Shot Systems suggest using a minimum of
a single phase 60 hertz 0.050kVA transformer. They are available for purchase through Hot
Shot Systems, just request when ordering.
 Mount a 3 terminal fuse block and a 120vac relay. Hot Shot Systems suggest using a 115V AC
coil relay. They are available for purchase through Hot Shot Systems, just request when or-
dering.
 Wire two, 480v conductors through the first two fuses (1/2 or 1 amp each) to the primary side
of the step-down transformer. Terminals may be different according to the transformer
installed.
 Wire the 120v X1 terminal of the step-down transformer through the remaining fuse (1 amp)
which then goes to the first 120vac input of the Hot Shot Receiver (120 volt polarity does not
matter).
 Wire the 120v X2 terminal of the step-down transformer to the neutral 120vac input of the Hot
Shot Receiver (see diagram on the next page).
 Add a jumper from the first 120vac terminal to the Hot Shot Receivers relay COM. terminal
(see diagram on the next page).
 Wire the NO. terminal on the Hot Shot Receiver to one side of the 120v relay coil.
 Connect the other side of the relay coil to the X2 terminal of the step-down transformer.
 Connect a wire from the Lighting Ground terminal of the Hot Shot Receiver to the ground
lug of the pump panel.
CAUTION: Never switch any voltage greater than 120v with the Hot Shot Receivers internal
relays. This will ruin the relay and void all manufacturer warranties. Use an externally
mounted 120v coil relay to switch all voltages greater than 120v. See diagram on next page.
HOT SHOT RECEIVERS NEED TO BE TURNED ON BEFORE THE HOT SHOT TRANSMITTERS
ARE TURNED ON. HOT SHOT TRANSMITTERS ONLY TRANSMITT FOR 1 MINUTE. IF THE RE-
CEIVER IS TURNED ON AFTER THE TRANSMITTER IT WILL NOT OPERATE CORRECTLY UN-
TIL THE TRANSMITTER IS SET TO TRANSMITT AGAIN.
