TYPICAL HOT SHOT RECEIVER HOOKUP TO SHUTDOWN
A ENGINE DRIVEN WELL
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. Turn on function switch 6 and turn on the power to the receiver to enable the Engine
Startup Mode (
for details see pg 4
). When activated the Supervision LED will come on and bypass the Murphy
switch to allow the engine to start and stay running until the transmitter has sent its relay ON command to the
receiver thus ending the bypass timer and taking control of the receiver and turning off the Supervision LED. If
the transmitter has not sent the relay ON command within 15 min the receiver will kill the engine and you will
have to turn the receiver off and then back on again to get it into Engine Startup Mode again. Now when the
pivot is finished or the safety is tripped the receiver will be sent a stop water signal, the receiver’s relay will
close COM to NC. This shorts the
S
terminal to ground and kills the engine. Other variations and Murphy Kill
switches will work as well.
