Dear customer,
the electronic anti collision light ACL-UAV-12V is a highly innovative product which contributes to saver airspace.
The new LED technology allows an incredibly excellent, red light with only approx. 10% of the input power compared with
conventional lights. The casting in a high-optical plastic makes the ACL absolutely insensitive against water, vibrations and
other environmental influence. The efficiency of the output is much higher, than with conventional electric light bulbs. The self-
warming of the ACL is low and can be determined as safe. To avoid overheating, the heat balance is controlled electronically.
The ACL-UAV-12V has additionally a serial FLARM-Interface. With this interface (19.200 Baud, 8 Bit, No Parity, 1 Stop-Bit) a
Power-FLARM unit can send the emergency level (0-3) and thus control the action replay of the ACL4.
Important:
connect
the shielding of the cable only at the ground of the Power-FLARM to avoid buzz loops and therefore interferences.
In addition, the ACL-UAV-12V has a remote control input and can be switched on and off by a radio control unit with a pulse
length of 1-2 msec or by potential free contacts (Relay).
This anti collision light for ultra light aircraft is designed to be mounted at a suitable position at the tail unit or at the top of the
stabilizer. Please adhere to the following instructions for a professional mounting of the ACL. The illumination angle complies
to the regulations for general aviation.
Required materials and tools
l
3-core twisted cord, according to the length of fuselage (5 - 8 meters)
l
1 shielded wire for Flarm-Interface
l
colored silicone
l
2 screws, approx. Ø 4 mm x 30 - 35-mm length
l
soldering iron, tin solder
l
shrink hose (enclosed)
Recommendations
Cable
2
We recommend a tripple core, flexible and twisted cable with a cross section of at least 1.0 mm and minimum 0,25 mm² for
remote control. In case of doubt, you can order the suitable cable from Thiesen Electronics GmbH. Use a single-wire shielded
cable for the FLARM-Interface.
Adhesion
We recommend standard silicon in a tube. It is available in do-it-yourself markets. This adhesion is strong and in case of a
dismantling you only need a sharp knife. We strongly advise against using other kinds of adhesion, like polyester or epoxy
resin.
Mounting
Use 2 metal screws (Ø 4 mm x 30 - 35 mm) to fix the ACL and a thin layer of silicon to paste it to the required position. By the use
of silicon twisting of the ACL is prevented and sealing against dirt and water is guaranteed.
Use only screws that do not
corrode!
Use metric screws, e. g. M4 with needed length for mounting with clinch nut or clamping nut. The ACL must be
mounted parallel to the longitudinal axis and vertically to the yaw axis of the aircraft (see illustration 1).
Mark the mounting position exactly. Clean and degrease the mounting position with grain alcohol or low aggressive thinner.
The adherend should be free from grease and free from polish. Drill 3 holes - two holes for the attachment screw (e.g. Ø
