The receiver unit is normally installed in the driver's
cabin, out of EX defined area.
Before installing the receiver, it must be carefully
considered the position inside the drivers cabin.
On dispensers the receiver is often installed in the
front of the cabin, using the standard antenna, like on
photo 2 and 3.
In cabins with windows on all 4 sides, it is a good
possibility for sufficient radio signal unless if the
windows are treated with materials to reduce direct
sunshine, this may also reduce the radio signals.
If the receiver is installed in a lover position, like on
photo 1, it is recommended to use the external
antenna solution.
At the receiver front panel is the recharging and
stow station for the transmitter. When stowed the
integrated battery is automatically recharged. It is
important that the installation of the receiver is done
for easy access for the driver, in order to stow the
transmitter for charging after every refuelling
operation. The orientation of the receiver is not
critical regarding the antenna. It must however be
considered that a lot of metal close to the antenna
could reduce the radio signal, and reduce operational
range and also the operation stability.
On photo 2 and 3 the antenna is free to receive in all
directions.
If an external antenna must be used, several options
are available. See section 2.3 to 2.8.
The receiver must have connection to power
supply/battery, 12 or 24VDC, the fuel valve,
controlling the fuel filling of the aircraft and the
warning indicting lamps.
NOTE: When installing the receiver unit, it should
be considered to installed it in a place with
temperature within 0 and +50ºC. This is vital since
the transmitter battery, NiMH does not charge
properly outside this temperature range.
If the temperature is outside these limits, it is
recommended to use a mains transmitter charger,
CH300 in a room with controlled temperature. See
section 5.2.
