1 Installation

1.1 General information

All remote control receivers for forestry winches are equipped with a standard 7 pin or 13 pin
plug.

In general, if the make and model of the winch was specified with the order, the
plug will be correctly configured for the customer. However we strictly
recommend that the wiring between the winch and the plug is checked, to
ensure that it is correct. On the last page of this manual you will find the
configuration of the plug for your winch, please compare this against the wiring
information in the winch user‘s manual.

Once the 7/13pin plug of the remote control receiver is connected to the
corresponding socket on your winch, the unit is ready for operation !

After charging on the LG2 battery charger the transmitter is ready for use. (See section 5.1

for charging instructions)

1.2 Mounting of the receiver

There are 4 holes in the back of the receiver box for fixing the unit to the vehicle with 4 to 5
mm diammeter screws. The holes can be accessed simply by removing the plastic strips on
the top of the receiver housing however, to fit screws into the holes, the lid of the housing
will probably need to be removed. This is done by removing the plastic strips, and then
unscrewing the screws that hold on the lid. After the lid has been removed, the receiver can
then be fixed to the skidder with suitable screws.

If possible please use rubber vibration absorbers that reduces the mechanical stress for the
complete unit (they are available at your service station). Due to the special case
construction the receiver is resistant against splash water and dust.

Please do not screw the moun

ting screws directly through the top cover

of the receiver. There will be big tensions that can cause a break! Do not

install the receiver directly at the winch without adequate protection

against mechanical and weather impact!

In case you use the system on a detachable winch, mounted on the tractor using a standard
three point attachment point, it is recommended that the receiver is also not permanently
connected to the tractor. If the receiver is permanently connected, and the winch is
detached from the tractor, without unplugging the control cable, it is very likely that the cable
will be torn out of either the plug or the receiver. If the receiver is simply lying in the tractor,
for example, it is less likely that damage will occur.

2 Operation

2.1 General information

The remote control series HM22xx conforms to the highest standards of safety (Details are
available in section 4.1 of this manual). The unit performs a self test every time it is switched
on and the internal status is permantly monitored. As a safety feature, if the unit detects an
error, it turns itself off. See also the block diagram in the appendix.

LED Function

Green LED: Indicates that the unit is in its standby mode
Red LED: Indicates that the unit is in its active mode
Yellow LED: Indicates the reception of a radio signal

Standby mode

The receiver unit is switched on by pressing the momentary action push button on the front
panel. The green LED should illuminate, indicating that the unit is in the standby state (see
also section 4.2).

N.B. The illumination of the Green LED indicates the standby mode.

The remote control of the receiver is still disabled until correct operation of the handheld unit
is confirmed. This is done by pressing and releasing any button on the transmitter. If the
transmitter is determined, by the receiver, to be operating correctly, the user can then
proceed to switch the system into the active mode, as explained below. (This feature
prevents unwanted and dangerous operation of the winch due to faulty parts or sticking push
switches on the transmitter unit)

Active mode

The following combination of button pressed on the transmitter will switch the receiver unit
from the standby mode into the active mode

press and hold Gas+

press and release Stop

release Gas+

The red LED on the receiver should now illuminate, indicating that the unit is in its active
mode. This means that the remote control functions are now enabled, and the system can
now control the winch (see also section 4.2).

N.B. The illumination of the red LED indicates the active mode.

3 Safety instructions

The use of radio remote controllers lightens the load of daily work, while increasing
the daily yield.

However, in contrast to when the operator is standing next to the skidder, operating
the winches manually, the operator may be some distance away and may not be able
to appreciate the tension or strain on a winch cable, or the pull on the skidder. This
increases the chance of the system being overloaded, in which case the cable can
snap or the skidder can turn over.

It is for this reason that the operator is urged to keep a good distance from the
skidder and from loads pulled by the winches. He should keep at least half a cable
length from the whole system!

If a load becomes jammed, and the operator goes forward to work on it, the receiver
should be switched into the standby mode by pushing the Stop button on the hand­held transmitter (see section 4.2).

The operation of the HM22xx radio remote control systems was designed to eliminate
the adverse of dangerous effect of interference or malfunction.

HM-Funktechnik, however, strictly recommends that if a user has any problems with a
unit it should be taken out of operation. It should then be checked by a skilled and
experienced electronic engineer, or sent to the service agent.

4 The receiver unit

4.1 Safety functions

4.1.1 Self test

The receiver has two main safety functions:The first is a continuous monitoring of the circuit
operation. If at any time the system detects a malfunction, the receiver unit will be switched
off automatically. The second safety feature is that the operator can isolate the control
output voltage from the control relays at any time. This function disables all the control
outputs, so that the remote control of equipment is disabled.

4.1.2 Control isolation

The output relay bus-bar voltage is available externally (units with a 13 pin plug only). This
allows the connection of a status indicator, for example a lamp on the back of the vehicle, to
show the operator the current status of the receiver unit. This would be a safety tool, as it
indicates to the operator whether the system is in the standby mode or in the active mode.

The receiver is programmed to test these two safety functions periodically.

4.1.3 Manual alarm function

The HM22xx systems have a manual or passive alarm operation. To activate the manual
alarm the operator must press the Stop button while holding down the Hupe button on the
transmitter. This will switch the external alarm relay and can be used to trigger an
emergency call system, such as the HM WECC2.

11

4.1.4 Automatic alarm function

This function will only be active if the DIL switch no. 3 is set to enable it (see section 4.6).

If the receiver is on, and the operator does not press a button on the transmitter for six
minutes, the receiver switches into alarm mode and initiates a prealarm warning via the
vehicle horn. If the operator does not respond to this by pressing either the Gas+ button or a
Ziehen button, after a further two minutes, the receiver will switch into an external alarm
mode. An extern alarm trigger signal is given as an output from the receiver unit and, as
described above, it can be used to trigger an emergency call system such as the HM
WECC2.

4.2 Safety functions during operation

In case the operator has to work on a load, which is already connected to the skidder´s
winch, he is reminded to use the standby safety function. He can switch the relay bus-bar
voltage off, just by pressing the Stop button on the hand-held transmitter.

This function disables all the remote control functions so that, if the operator inadvertantly
presses a button on the transmitter, the winch is not set into operation. This control driver
voltage can be switched on again according to the procedure described in section 2.1.

4.3 Power supply requirements

The receiver unit is designed for operation on equipment with a 12 or 24VDC supply and
there are no adjustments or modifications needed. The voltage supplied to the unit from the
vehicle is switched through relays to give the control output signals, so that 12VDC is
supplied, the outputs will be at 12VDC, or if 24VDC is supplied the outputs will be at 24VDC.

4.4 Control output protection

In the receiver each output relay is protected by a 6 A poly-switch fuse installed in series
with the output relay contacts. If a maximum current of 6 A is exceeded on an output, due to
a short circuit or excessive load, the fuse will drop out and isolate that output. The fuse will
then automatically reset after the short circuit or excessive load is removed from the output.
These fuse elements are not permanently damaged by short circuits, and they protect the
rest of the circuitry from being damaged, however, they may become hot if any output is
constantly overloaded and this heat can damage the output relays.

For future use

2 Self test relay: O

n start up this relay is latched by pressing the button on the front

panel of the receiver unit.

If the self test routine of the microprocessor detects a malfunction at any time this

relay will be reset, completely isolating the unit from the vehicle power

supply. The

normal start up procedure can be used to restart.

3

It can be used either to drive a warning light, whenever the winches pull in cable, or to

control an hydraulic pump whenever the hydraulic system is used. The function of this

relay is controlled by DIL switch no.5 (see section 4.6 for details)

4

This relay is in series with the self test relay and switches the control relay bus

voltage. R4 can be latched on start up, after the self test funcion is complete, by

pressing the Stop button while holding the Gas+

button pressed (the normal methode

of switching into active mode)
R4 is alo used to switch between standby and active mode: The Stop

button is used

to enter Standby mode, isolating the control relays, and the same sequence as above

to enter the active mode.
The output of this relay is also available externally on the 13pin plug.

5 This relay switches if the Hupe and K. Lösen I buttons are both pressed on the hand-

held transmitter. This relay can be used to drive an engine start mechanism.

6 This relay can be used to initiate an external emergency call

. The function is

controlled by DIL switch no. 3 (see section 4.6 for details)

7 This relay switches if the Hupe and K. Lösen II buttons are both pressed on the hand-

held transmitter. This relay can be used to drive an engine stop mechanism.

8 This relay switches when the Hupe button on the hand-

held transmitter is pressed.

The output is normally open circuit and switches to the supply voltage of the vehicle

(12 or 24 VDC).
It is recommended that an external relay is installed to drive the horn

, as the horn

may draw a large current. This would cause the polyswitch fuse to drop out, and as

described above this can eventually damage the output relay.

9 This relay is controlled by the Ziehen I button on the hand-

held transmitter. It is used

to drive the clutch on winch no.1.

10

This relay drives an actuator to control the skidder´s accelerator mechanism in the

funktion Gas-. Its function is controlled by DIL switch no. 2 (see section 4.6 for details)

11 This relay is controlled by the Ziehen II button on the hand-

held transmitter. It is used

to drive the clutch on winch no.2.

12

This relay drives an actuator to control the skidder´s accelerator mechanism in the

funktion Gas+.Its function is controlled by DIL switch no. 2 (see section 4.6 for details)

13

This relay is controlled by the Lösen I button on the hand-held transmitter. It releases
the brake on winch No.1. It is controlled by DIL no. 4 (see section 4.6 for details).

14 This relay is controlled by the Lösen II button on the hand-held transmitter.It

releases

the brake on winch No.2. It is controlled by DIL no. 4 (see section 4.6 for details).

5 The transmitter unit

In the hand-held remote control unit, apart from the radio transmitter module, there is an
encoder, which formats the control data for transmission, and a battery charge management
unit, which permanently monitors the state of the internal battery.

5.1 Charging the hand held transmitter unit

There is a 4.8V NiMH battery permanently installed in the transmitter. The charging cycle of
this battery is controlled by the battery charge management unit.

There are two metal belt loops on back of the transmitter unit. These loops are also the
charging contacts for the internal NiMH battery. These contacts are short circuit protected!

The battery can be charged by slotting the transmitter onto the LG2 battery charger, or any
12VDC source can be used to charge the battery by connecting it accross the two belt loops
(the polarity does not matter).

5.2 Battery charging cycle

When the transmitter is put on to charge the internal circuitry first discharges the battery
completely, to prevent damage to the battery and to maximise its working life of about 1000
charging cycles. The battery is then charged from flat. The discharging can take up to sixty
minutes, and the charging can take up to eight hours.

N.B. The complete charge needs minimum nine hours and the temperature shouldn`t be
below 0°C (32°F).

If the battery is discharged to 30% (for example) of its capacity during the day’s work, when
it is put on to charge, the internal charging circuitry will first discharge the battery completely,
then begin to charge it. This means that putting the unit on to charge for a short time when
the battery is not completely flat may, in fact, decrease the residual charge in the battery.

Important:

Charge the transmitter over-night by leaving it on the LG2 charger or
connecting it to any 12VDC voltage (polarity does not matter). If you want to use
the charging function during a working break please push together the buttons

Gas- and Gas+ after putting the transmitter on the charger. This charging is
limited to one hour.

5.3 Low battery warning

If the residual charge in the battery decreases to about 10% of its maximum capacity, while
in operation, the operator will be warned via the vehicle horn: It will sound for about 1 sec
each time any button on the transmitter is pressed (except the Stop button). This ten
percent is sufficient for a further four to five hours normal work, but this warning informs the
driver that the battery is almost flat and should soon be put on to charge.

A completely charged battery allows a couple of days of operation, depending on how much
the transmitter unit is used: The battery capacity is enough for about 18 hours continuous
transmission (pressing any button permanently).

15

5.4 Data format

The HM22XX radio remote control systems use an highly sophisticated data protocol
between TX and RX. Apart from the control functions, a 16 bit system address and
incremental code element is transmitted, which gives the code a unique format. If the code
were transmitted continuously, it would repeat about every 30 years.

5.5 Radio licence

The HM22XX series remote controllers use HM-Funktechnik GmbH radio modules 70TXRX­M1 for the data link.

The used radio modules 70TX-M1 and 70RX-M1of HM-Funktechnik GmbH are approved by
the FCC under the code PUX and also fulfil the European R&TTE directive.

6 Trouble shooting

If the remote control system doesn`t work, please check first the wiring on the skidder. Is the
plug inserted correctly? Are the contacts of the plug clean, dry and not oxidized? Is the cable
ok and without damages?

Did you charge the battery?

Does the the receiving signal lamp at the receiver lightens when you push a button on the
transmitter?

Do you hear the clicking of the relays when you push a button on the transmitter. If yes,
please check if the driver voltage is activated and the red LED lightens?

Is there maybe a short-circuit in the cable to the winch due to wrong modifications?

If nothing helps please contact our service. They will help you in either case. If it is
necessary to send in the remote control system for service please don`t forget to add a short
failure description. It is often very hard to find a failure that is not obvious or not constant.

For further information please contact our service department or your dealer. The HM­Funktechnik service department is available via phone no. [phone]
