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.
