NSTALLATION OF THE RECEIVER
Installation in drivers cabin
External long range antenna (Optional)
Figure 2.1 Receiver and Transmitter in the driver's cabin
The receiver unit with antenna is normally installed in the driver's cabin, out of EX defined area.
The receiver must have connection to power supply/battery, 12 or 24VDC, and the fuel valve,
controlling the filling of the aircraft.
The receiver front panel is also the charging station for the transmitters battery. It is important that
the installation of the receiver is made so that it is easy to reach for the driver, in order to place the
transmitter for charging each time it has been used.
The orientation of the receiver is not important regarding the antenna. It must however be considered
that a lot of metal close to the antenna could reduce the radio signal strength, and reduce operational
range and also the functional stability.
If an external antenna must be used, up to 1,5m from the receiver unit, it must be connected by a
coaxial cable, and the antenna must be mounted vertically on a metal base.
If several antennas are installed on the truck, the DE212 antenna should be at a distance to other
antennas of no less than 1m.
NOTE: When installing the receiver unit, it should be considered to installed it in a place with
temperature within 0 and +50ºC. This is because, the transmitter batteries, NiMH does not charge
properly outside these temperatures.
If the temperature is outside these limits, it is recommended to use a mains battery charger, CH300
inside in a controlled temperature area. See section 5.2.
