Transmitter
The transmitter generates an RF signal which is FM
modulated. The Modulation is a 120 bit data stream with start
and stop bits, information concerning the selected switch
being activated, and a specialized algorithm developed to
ensure the validity of the transmission. Also transmitted are
address information to enable it to “talk” to its associated
receiver. This address information is set at the factory so no
two devices will be the same. There may be over 20000 units
in the same vicinity without any cross activation.
Receiver
The receiver receives the signal transmitted by the
transmitter, decodes the data stream and checks for validity
of the address and the start and stop bits of the received
data. If this is correct, a proprietary software algorithm is
performed to accept or reject the information to be passed on
to the outputs. If for any reason this test fails, no output will
be allowed to function. Once this test has passed, the
appropriate output will be activated.
Single Proportional Control
The radio system is designed with its own amplifier circuit
that supplies a pulse width modulation output. (An
independent amplifier card is not required for the
proportional valve.)
Input Voltage ............................. 10-30 VDC
Output Voltage .......................... Same as input voltage
Output Current .......................... 5 amps maximum
Proportional Setting .................. Independent low end /
high end settings
The independent proportional low and high end settings
match the potentiometer travel with the proportional valve’s
working voltage and range.
The proportional valve is remote mounted between the
hydraulic reservoir and the existing valve bank. A trigger
controlled potentiometer is mounted in the grip of the hand
held control that is spring loaded. This creates a single
control, “metering” fluid to all the valves mounted on a
manifold.
Electrical Circuit Description
Receiver Electrical Supply
1.
Positive 12 VDC power is supplied from the battery to a
15 amp thermal circuit breaker then to plug letter “A” in
the receptacle.
2.
When the receiver cord is plugged in, +12 VDC power
becomes available to the receiver.
Hand Control Circuitry
1.
The hand control (transmitter) is activated by turning the
power switch to the ON position. The radio transmits ten
seconds to “initialize” the receiver.
This switch should
be placed in the OFF position when not using the
remote controls.
Failure to do so will greatly reduce the
life of the 9 volt battery in the hand control (transmitter).
2.
OFF-START switch in “CENTERED” position.
a.
Ignition circuit not energized until truck is started.
3.
OFF-START switch in “START” position (Momentary).
a.
“L” (Ignition) circuit energized and stays energized
when switch returns to central position.
b.
“M” (Start) circuit energized to power start relay at
truck engine.
c.
“N” (Throttle Advance) circuit energized to power
the throttle advance relay at truck engine (if
equipped).
4.
Function Switch (Turn, Telescope, Hoist, Boom, etc.)
thrown (Momentary).
a.
Energizes the selected circuit to power one of the
solenoid valve coils at the crane frame.
b.
At the same time, energizes “N” (throttle advance)
circuit to power the throttle advance relay at the
truck engine (if equipped). Throttle stays activated
for five seconds after function switch is deactivated.
5.
Trigger
a.
Attached directly to potentiometer shaft.
b.
Controls the speed that a crane function will
operate. The more it is moved, the faster the
function will operate.
Emergency Stop Function
This unit is equipped with an Emergency Stop. The
transmitter has a momentary push button switch near the
antenna. When initially using the radio remote control
system, turn the receiver power on first. This allows power to
the microprocessor and awaits for a special code from the
transmitter to activate a relay to make power available to the
output driver circuit.
When the transmitter is turned on, it will transmit a special
code for 10 seconds to instruct the receiver to initialize. This
will happen only if the transmitter is Not transmitting a
function such as switch being activated. During this initial 10
seconds a function may be activated once the receiver has
been Initialized. The initialization is instantaneous so you will
not have any delay in operation. If the transmitter is “out of
range” or a function is activated when the transmitter is
DANGER
Failure to do so could cause inadvertent operation of the
crane.
