SYSTEM OVERVIEW
Theory of Operation
The Hetronic radio remote control system includes a
transmitter and receiver. The transmitter electronically
generates a carrier frequency which allows it to
communicate with the receiver. Each system is
programmed with a unique address code. This code
allows the operation of multiple systems in the same
general vicinity. The receiver only accepts commands
from the transmitter with the same address code.
NOTE: The receiver and transmitter have the address
code set at the factory.
E-Stop Function
The most important feature of the radio remote control
system is the E-Stop. The transmitter sends the E-stop
status signal along with the specified crane/machine
function. This method confirms that ongoing operations
are safe. If the E-stop pushbutton is pressed, the relay
module in the receiver causes all crane/machine
motions to stop. The receiver goes into Safe mode.
To restart the system, disengage the E-stop button and
press the Start/Horn button.
The E-Stop responds faster than any other function.
When E-Stop is engaged, the system ignores any other
signal that is transmitted. The problem must be
corrected before the system will respond to any other
signal.
The E-Stop is self-monitoring and redundant in the
transmitter and receiver. The system performs a
self-test to ensure the E-Stop circuit is working
properly. If an error is detected, the system
automatically goes into Safe mode.
When the transmitter is turned on, it performs a
self-test to be sure that communications are within
designated parameters. If an error is detected, the
transmitter will not transmit any signals.
Transmitter Sleep Mode
The transmitter sleep mode is designed to prevent
accidental operation. If the transmitter is not used for
10 minutes, it turns itself off. The controls are not
operational while the transmitter is turned off. To restart
the transmitter, turn the key switch off and then back
on, and press the Start/Horn button. The sleep mode
can be enabled or disabled by the operator.
IMPORTANT: If the transmitter has a selector switch or
latching pushbutton that is engaged, the sleep mode
will not occur. The engaged selector switch or latched
pushbutton is constantly sending a signal to the
receiver.
Receiver Safe Mode
The following conditions cause the receiver to go into
its Safe mode:
• The transmitter goes into Sleep Mode
• Radio signal interference
• Transmitter out of operating range
• E-Stop button is activated
• E-Stop circuit failure
• Low battery sends E-stop after time out
When the transmitter signal is no longer sensed by the
receiver, the Time Out process begins. The Time Out
period is set to 450 msec at the factory. If the receiver
does not establish contact with the transmitter within
that time period, it goes into the Safe Mode. In Safe
Mode, the receiver shuts off power to the output
modules and activates the E-stop function.
To restart the system, be sure the transmitter signal is
active and sensed by the receiver. Then press the
Start/Horn pushbutton.

Car Antenna Installation
If the receiver must be located inside a control panel or
other enclosure, an external car antenna may be
required. Mount the antenna onto a metal surface with
the same ground as the receiver circuit board. Remove
any burrs from the antenna mounting hole and scrape
away any paint which may insulate the antenna base
from making positive contact.
NOTE: Improper installation of the antenna will cause
intermittent signal loss.
1. Drill a hole 14 mm (.56 in.) dia. through the
control panel or enclosure at the external car
antenna location.
2. Insert the connector base through the hole with
the antenna on the outside. Seat the base firmly
against the enclosure surface.

4. Screw the antenna pole onto the antenna base.
5. Remove the Miniflex antenna from the receiver
housing by unscrewing it from the antenna base.
6. Connect the external antenna cable to the
antenna base on the receiver housing.
7. Bundle any excess antenna cable and secure
with tie wraps or equivalent.
IMPORTANT: DO NOT run the antenna cable with
power or control wiring. Intermittent signal loss will
result.
GainFlex Antenna Installation
Your application may require the use of a GainFlex
antenna. The GainFlex antenna can extend the range
of the radio remote control system up to 300 meters
(1000 ft.). It can also be used where a standard
antenna is difficult to mount. If you are not sure which
antenna is suitable for your application, please contact
Hetronic or your dealer.
When using a GainFlex antenna, there must be no
metal or conductive materials within 2 meters (6 feet)
of the antenna. This material will interfere with the
transmitter signal and cause intermittent signal loss.
For the best reception, the antenna should point
upward.
NOTE: Improper installation of the antenna can cause
intermittent signal loss.
1. Secure the GainFlex antenna base to a mounting
surface with the tie wraps included. Mount the
antenna vertically with the base pointed upward.
2. Screw the GainFlex antenna pole onto the base.
3. Unscrew the Miniflex antenna from the receiver
housing.

FREQUENCY AND ADDRESS SETTINGS
Each Hetronic radio remote control system contains a
radio frequency (RF) unit. Each system consists of a
transmitter RF unit and a receiver RF unit.
The address settings are pre-set at the factory in the
ADMO module. However, if the transmitter coder
board, the base board, or if the entire transmitter or
receiver are replaced, the ADMO address must match
the system.
IMPORTANT: If the ADMO settings of the transmitter
and receiver do not match, the system will not function.
CAUTION: AVOID INJURY OR DAMAGE -
Operating the transmitter without its antenna
could destroy the final stage of the RF
module. DO NOT attempt to change the
Hetronic pre-set frequency or the 16-bit
address. Personal injury and property

Receiver
The receiver uses LEDs to indicate operational status.
The cover of the receiver must be removed for the
LEDs to be visible. See "Test the Receiver" in the Test
Procedures Section of this manual for specific
information on LED locations.
TRANSMITTER OPTIONS
Each Hetronic radio remote control system is built to
customer specifications. You may have features that
are not described in this manual. Some possible
options are described below. If you have questions,
please contact your dealer or Hetronic.
Back-up Transmitter
Spare transmitters are frequently used in the event that
the primary transmitter is damaged or misplaced. Only
one transmitter is allowed to be active at any given
time.
NOTE: If the primary and back-up transmitter are
turned on at the same time, the receiver enters the
Safe Mode.
ADMO Address Plugs
If several radio remote control systems are used,
address plugs can configure a spare transmitter to be
used on any of the cranes/machines. Each address
plug corresponds to a specific crane/machine. When a
specific crane/machine address plug is inserted into
the plug receptacle of the spare transmitter, the
transmitter is automatically configured to operate that
crane/machine.
Optical Low Battery Indicator
This feature is a LED indicator of the low battery
condition. It can be used as an alternative to or in
addition to the buzzer signal.
Advanced Low Battery Indication
This feature is basically a timer that indicates a low
battery condition 10 minutes before the Safe Mode is
entered. This feature is beneficial where placing the
crane or machine in a safe position takes more time
after the low battery is indicated.
Feedback
This feature allows the transmitter to receive and
display information such as crane/machine status,
warnings, etc. The feedback can be displayed as visual
graphics or buzzers.
RF Booster
This feature boosts the RF transmission power for
extended range operation of up to 1 mile. It is to be
used only in applications that are safe to operate
outside of the operator’s visual range.
Priority Transmitters
This feature is the capability to have several
independent cranes/machines controlled by one
transmitter. Priority leves can be set to allow the main
transmitter to override the control of individual
crane/machine transmitters.
RF Units
AUTX - Auto Synthesizer - The function of a transmitter
to automatically search a range to find a frequency
without interference.
SCRX - Scan Synthesizer - The function of a receiver
to respond only to a designated transmitter and finding
the frequency that the transmitter is transmitting on.
CRANE/MACHINE CONTROL WITH
MULTIPLE TRANSMITTERS
Multiple crane/machine applications may require the
use of more than one transmitter. Or a single
transmitter may be required to control several
cranes/machines simultaneously. The common
methods of control for these situations are "Pitch and
Catch" and "Independent/Combined Control."
Pitch and Catch
Multiple (usually two) transmitters control one receiver,
but not at the same time. All transmitters must be
configured with the same address code as the receiver,
but set at a different frequency channel.
The first transmitter turned on controls the
crane/machine. The operator moves the load to a
hand-off location and turns the transmitter off. The
second operator turns his transmitter on and takes
control of the crane/machine. The receiver only
accepts commands from one transmitter at a time.
Independent/Combined Multiple
Crane/Machine Control
This configuration is for applications that require
multiple (usually two) cranes/machines on a single
runway. Each crane/machine can be controlled
independently. The cranes/machines may also be
operated in tandem by one operator.
The transmitters built for these applications contain
Selector switches. These switches select each
crane/machine individually or any combination of
designated cranes/machines.
With transmitter interlocks, each transmitter contains a
different address code and frequency channel. The
receivers have a RF module and decoder set for each
transmitter. A special module inside the receiver
determines which transmitter is requesting control of
each crane/machine. The module locks the transmitter
signal to the receiver and all other transmitter signals
are ignored.

20
When that transmitter is turned OFF, the
cranes/machines are available to be controlled by a
different transmitter.
Universal Transmitter
One transmitter is engineered to communicate with
several different systems. The transmitter can be
quickly modified to control any crane or machine in a
designated facility or fleet.
OPTIONAL SAFETY FEATURES
"Press to Operate" (PTO) Safety Switch
To release a crane/machine load, it may be necessary
to incorporate a two-handed activation with a "Press to
Operate" (PTO) safety switch. The PTO switch must be
activated at the same time the load release switch is
activated. This feature ensures that the load is not
released by incidental activation of the release switch.
Typical applications for a PTO switch are magnetic and
vacuum lifting devices or grabs of any type.
A PTO safety switch can also be incorporated into a
joystick as a button on top of a joystick lever.
"Lift to Operate" (LTO) Joystick
"Lift to Operate" (LTO) joysticks have a mechanical
device located near the top of the joystick handle. It
must be held and lifted upward to activate the joystick.
LTO ensures that the joystick is not accidentally
activated. This feature is available on GR transmitters.
"Lift to Operate" (LTO) Toggle Switch
LTO toggle switches must be lifted from their static
positions in order for the switch to be activated. LTO
toggle switches can be "maintained" or "momentary".
This feature is mechanically activated and is available
on Nova, GL, and GR transmitters.
Tilt Sensor Switch
The tilt sensor switch activates if the transmitter is tilted
more than 30 or 45 degrees from level. The switch has
a delay time of 0-5 seconds.The delay time is set at the
factory to customer specifications. If this switch senses
an unacceptable tilt for as long as the time delay is set,
the transmitter either sends the E-stop signal to the
receiver or enables/disables certain functions
according to customer specifications. This safety
device is useful if the operator is in danger of losing his
footing or control of the transmitter. It is available on GL
and GR transmitters.
Range Limitation
This feature uses a RF signal to restrict operator
movement to a predetermined range limit. It can be
preset at the factory, or adjusted in the field.
Interlocking Functions
This feature prevents contradictory operator
commands from the transmitter. Certain functions can
be enabled or disabled when another function is
activated or inactive. An example is hoist up and hoist
down. Activating both functions would most likely
damage the equipment. Therefore, hoist up is
interlocked with hoist down so that when one is
activated the other can not be. The systems are
capable of interlocking any functions.
Magnet Switch
The magnet switch is used mainly in transmitter
docking station situations. Its function is to enable
certain functions only when the transmitter is secured
in a predetermined location.
Corrosion Protection
To resist damage in corrosive environments, all metal
components are fabricated of stainless steel. This can
include receiver housings, hardware, screws, etc.
Solid State DC Outputs
This feature enables Hetronic to eliminate costly
intermediate relay panels for DC crane/machine
operations. There are no moving parts in the
contactors, thereby lowering maintenance costs.
