THIESEN ACL-UAV-12V User guide

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
l3-core twisted cord, according to the length of fuselage (5 - 8 meters)
l1 shielded wire for Flarm-Interface
lcolored silicone
l2 screws, approx. Ø 4 mm x 30 - 35-mm length
lsoldering iron, tin solder
lshrink 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

Electric power supply / cable connection to the aircraft system (12 Volts)
The best connection is solder with additional shrinking of the soldering joint with a shrink hose (enclosed). Only use solder for
electronic soldering never use cored solder. It contains acids which cause corrosion!
Important notes
Carefully mount the cables inside the rudder and/or the fuselage. Connect the cables professionally to the aircraft system
(red = positive, ) and to a 5 Amps fuse protection. Luster terminals are black = negative, blue = radio control, green = FLARM
not suitable to connect cables. There is a good selection of suitable crimp connections in various shops.
Servicing / maintenance
For additional UV protection, use varnish. Should the ACL be scratched, use a good polish to refurbish the damages. With
slightly deeper scratches use wet sandpaper with very fine granulation (800-1000) carefully polish again. Do not use
aggressive chemicals like gasoline or solvent.
For day to day cleaning use soap water!
Some insect removers and detergents forces embrittlement of epoxy based plastics and laminates. Use only aircraft certified
products. If the aircraft can not hangarized, please cover the lamps to prevent surface aging!
Pasting
Apply only as much silicone as required to paste the ACL plane (see illustration 2). After fixing the ACL to the required position,
slightly tighten the screw. With your moistened finger using dish liquid clean off any laterally dispensable silicon, a smooth
transition can be modeled between the wing and the ACL.
Silicone needs time to cure (vaporization of acetic acid). The best results are achieved at a temperature of 20° Celsius (68°
Fahrenheit). Just follow the handling instructions of the silicone. The final firmness (stability) will be reached after a few days.
