Farm and Business Communications manufacture Radio Control Equipment for the
remote operation of Diesel Pumps and Generators, using over air signaling.
The Control unit for use at the engine site has been designed to use
Microprocessor Technology to allow simple installation and operation of all
functions of control at the engine site. Operation of starter solenoid, glow
plugs, fuel circuits, and generator circuits, can all be controlled during
startup and close down using the control unit. All functions of startup and
timing can be preprogrammed simply.The length of time that the Diesel will run can also be set over air via radio. Operation of the engine can be monitored using inputs on the Control Unit, and any failure can be used to close the engine down and send a Selcall alarm signal to the base radio ( Homestead ). It is also possible to listen to the engine running.
The control and activation of the engine site is achieved using DTMF tone
sequences transmitted over radio. Security is maintained by the need to send
a unique code to each engine site, to allow its operation. The reception of
commands are confirmed by reply tones or optional voice confirmation.
The equipment is designed to be interfaced to most UHF CB or Commercial radio products with no need to modify the radio. Connection is simply made to the microphone input and extension speaker socket.
Programming of the engine control unit can be done on site, using a DTMF programmer, or over air using the Homestead Control Unit.
Farm and Business Communications manufacture a simple to operate Homestead based control unit for simple activation of all outsites. Three or Four Key strokes are required for the operation of up to 99 sites. This unit is also used to activate and check Tank monitoring units.
