Operating instructions
1. Safety
1.1. Safety of this radio remote control system
This radio remote control system is equipped with both electronic and
mechanical protection devices.
When allocated, coding applies to one transmitter only, meaning that control
commands cannot be received from other transmitters.
This concerns your safety
In the event of incorrect operation or misuse, there is a risk of harm to
- the health of the operator or other persons, and
- the machine and other property.
All persons working with this radio remote control system
- must be both suitably qualified and have been instructed as
required by regulations
- must strictly comply with the contents of these operating
instructions.
1.2. Safety information and tips
The following symbols are used for warnings and advisory notes in these
operating instructions, with the following meanings:
This symbol is used to warn you of the risk of fatal accidents or serious
injuries. Such risks can arise whenever operating or working
instructions are not strictly followed.
This symbol is used to warn you of the risk of damage to the machine or
to other property if the operating or working instructions are either not
followed or not followed properly. Disregarding these warnings may
void your warranty.
This symbol is intended to draw your attention to particular features or
important information designed to make your work easier.

1.3. Sources of risk
The system is designed for permitting machines to be controlled by radio
remote control.
However, since the control commands also are transmitted beyond your range
of vision, and through or around obstacles in the vicinity, you should always:
- Put the transmitter down only in a safe and dry location, switch
the transmitter off and pull the key from the key switch (or if your
transmitter does not have a key switch, remove the rechargeable
battery or the battery compartment).
- Disconnect the power supply before you start any installation,
maintenance or repair work!
- Avoid removing or modifying any safety devices!
1.4. Qualified operators
(Refer to the operating instructions for the machine you intend to
operate with this control system!)
The operator is responsible for ensuring that when the transmitter is put down,
it cannot be used by unauthorized persons. This can be done either by pulling
the key from the key switch, by removing the rechargeable battery or by
storing the transmitter in a locked location.
The owner must:
- provide the operator with these operating instructions
and
- ensure that the operator has read and understood them.
1.5. Safety precautions in the working area
- Ensure that there is no risk of slipping in the work area.
- Before each use of the radio remote control system, check that
nobody is within the working area or swiveling range of your load.
- If a carrying aid is prescribed for your transmitter, this is to be
worn during use.
Either turn the key switch to the off position and pull the key, or
remove the rechargeable battery or the battery compartment from
the receptacle when putting the transmitter down. This will prevent
undesired use or misuse of the transmitter by third parties.

1.6. Protection devices
The machine will be stopped:
- If you actuate the red EMERGENCY STOP button or the Stop button
on the control panel of the transmitter
- If the range is exceeded
- If there is receiver or transmitter interference or when the radio signal is
interrupted
- If the rechargeable battery or the battery compartment is removed
- If the rechargeable battery or non-rechargeable batteries is/are run
down
These protection devices:
- are included for the safety of both persons and property, and
- must not be modified, removed or bypassed under any circumstances
or in any way whatsoever!
Additional protection devices (depending on transmitter version):
- Guard rim, guard clip or recessed function buttons. These safety
devices protect against undesired actuation of the control elements,
which in turn prevents unintentional control commands from being
transmitted.
1.7. What to do in an emergency
In an emergency, immediately press the red EMERGENCY STOP button
or the other EMERGENCY STOP button on the transmitter control panel.
Then proceed as instructed in the operating instructions for your
machine. (Figs. 1 - 3)

2. Operation
Have you read and understood the operating instructions, in particular section
1 on safety and protection devices?
You may not use the device until you have done so!
2.1. Handling non-rechargeable/rechargeable
batteries
Depending on the version, HETRONIC radio remote control systems either
come with a battery compartment for two or three 1.5 V alkaline mignon
batteries
or
with a HETRONIC rechargeable battery/battery charger set (12/24 VDC or
115/230 VAC depending on the transmitter type) and two HETRONIC
interchangeable batteries
or
with a VersaPak rechargeable battery/battery charger set (115 V AC or 230 V AC)
with two interchangeable VersaPak penlite batteries rated at 3.6 V each.
If your HETRONIC radio remote control system was
delivered with a battery compartment for alkaline mignon
batteries, never attempt to charge the battery
compartment with the alkaline batteries in a battery
charger!
Alkaline batteries are not capable of recharging; only
batteries specially designed for this purpose can be
recharged!

2.1.1. Replacing rechargeable/non-rechargeable
batteries
Ensure that there is no dirt or grime in the non-rechargeable /
rechargeable battery compartment, as this can lead to breaks in contact.
Only use alkaline batteries. Zinc-carbon batteries are not suited for
powering the transmitter. The transmitter electronics continuously
monitor the battery voltage. When this has dropped below a certain
value, the operating LED on the transmitter begins to flash red, or you
hear an acoustic signal and the system switches off (handheld
transmitter versions excluded).
Proceed as follows:
- Bring the machine to a safe state within 30 seconds (transmitter
switches off after about 30seconds).
-Switch off the transmitter by turning the key switch to position 0 (if your
transmitter has a key switch).
Alkaline mignon batteries:
- Remove the battery compartment with the run down alkaline batteries
from the transmitter.
- Remove the run down alkaline batteries (two or three).
- Place two or three fully charged 1.5 V alkaline batteries in the battery
compartment as depicted on the latter.
- Insert the battery compartment in the battery receptacle of the
transmitter with the contacts first and the open side facing down, or
insert the battery compartment in the battery receptacle of the
transmitter with the narrower end first (see Figs. 4 and 6).
- Now press the battery compartment until it fully locks into place.
VersaPak rechargeable battery:
- Press the lever at the end of the rechargeable battery compartment until
the battery releases.
- Replace the run down rechargeable battery with a fully charged one.
- Press the end of the rechargeable battery until it fully locks into place
(see Fig. 5).
HETRONIC rechargeable batteries:
- Remove the run down rechargeable battery by pressing the edge lip or
battery cover forward, then pull up and out.
- Take a charged battery and insert it in the designated pockets of the
transmitter battery compartment with both contact points forward
(NOVA) or down (GL) and both guide rails down.
- Then press the rechargeable battery in the direction of the battery
receptacle until the battery fully locks into place (see Figs. 7 and 8).

2.1.2. Battery charger and charging the battery
Charging the rechargeable batteries:
- Remove the rechargeable battery as described in section 2.1.1.
- Then place the battery in the charger designed for your particular battery
(see Figs. 9 to 11).
- Ensure that the battery charger is connected to the respective power
supply (power plug, vehicle, etc.).
- Charging should take approximately 3 to 6 hours, depending on the
version. See section 6, “Technical data”, for more information.
Please make sure that you read the operating instructions
provided by the manufacturer for the battery charger prior
to use and that you follow all safety instructions contained
therein. HETRONIC will not accept liability for improper or
negligent use.
Only use genuine HETRONIC parts or parts approved by
HETRONIC. Not doing so introduces the risk of explosion!
Emitted chemicals and flying parts can cause injury.
Battery chargers from HETRONIC have a charge level
recognition feature that automatically switches the charger
to charge retention mode when the batteries are at full
capacity. Always leave one battery in the HETRONIC
battery charger so that you will have a fully recharged
battery in reserve at all times.
To prevent possible damage to VersaPak rechargeable
batteries and the battery charger: Please ensure that
VersaPak batteries do not remain in the battery charger for
more than 24 hours (only applies to VersaPak penlite
rechargeable batteries and the battery charger).
Batteries and rechargeable battery packs are to be treated
as hazardous waste!
Use a specialist disposal company for recycling and
disposal! Defective rechargeable battery packs can also be
disposed of directly through HETRONIC.

2.1.3. Battery chargers
Battery charger UCH-2-AC or UCH-DC
The battery charger contains a processor to control and regulate
the whole charging process. Depending on the version it is
designed for operating voltages of 10-30 VDC or 90-270 VAC.
After inserting the battery, a yellow LED indicates the charging
process. When the battery is fully charged a green LED lights
up. When you switched to fast charge a red LED lights up
additionally. If no LED is shining after inserting battery
on power at charger the yellow LED is flashing continuously,
the battery is bad.

2.2. Control elements
Please refer to the transmitter and receiver diagram included with these
operating instructions for the control element arrangement of your radio remote
control system. The diagram forms an integral part of these operating
instructions.
The following is a description of those control elements that are standard on
HETRONIC radio remote control systems.
2.3. Operation
Before you use the system, you must carry out the safety checks described in
sections 2.3.1. and 2.3.2. below.
These safety checks must be carried out at least once each day before you start
using the system or before each change of shift.
A diagram of your transmitter version is included with these operating
instructions. The diagram forms part of the operating instructions. The
arrangement of the control elements and the transmitter labeling will vary
subject to customer requirements, but generally will be the same as the
labeling of the previous controls. The only essential difference, in fact, is
that you will now be able to exert control without the need for cable
connections.
Refer also to the manufacturer's operating instructions for your
machine and the diagram of your transmitter version to familiarize
yourself with the arrangement of the control elements and their
functions!
The section below deals with the radio remote control system’s control elements
and special features.
Risk to life and property!

the STOP button during a safety check.
Continuous transmission mode: The radio signal and the EMERGENCY
STOP relay remain active until the transmitter is switched off.
- Now press one of the function buttons of the transmitter and keep it
depressed.

- Check the EMERGENCY STOP function as described in the
manufacturer's manual, however, instead of pressing the EMERGENCY
STOP button on the machine, press the Emergency Stop button or the
yellow STOP button on the control panel of the transmitter.
- Now press the EMERGENCY STOP button or the yellow STOP button
on the transmitter.
Once you have pressed the EMERGENCY STOP button on the
transmitter, it should no longer be possible to exercise control over
any of the machine’s functions!
- Have you completed the checks and does the EMERGENCY STOP
system function properly?
- Now release the function button and unlock the EMERGENCY STOP
button on the transmitter again.
- After the EMERGENCY STOP button has been unlocked and the
transmitter restarted, the system is ready for operation again.

transferred from the machine to the receiver. A diagram of your transmitter and
receiver version is included with these operating instructions.
