Specifications 27.40.39-004-28320930-2018


 

The obstruction lights ZOS-A are innovative and high quality aviation omnidirectional view light-signal devices intended for light twilight marking of high objects fully complying with ICAO.


The medium intensity obstruction lights ZOS were designed using the innovative experience of the leading world manufacturers of this type of aviation light-signal equipment.


The team of our engineers set up the target to provide the clients with the most efficient solution in terms of the modern and reliable equipment, which meets all expectations and needs as well as complies with the international and national regulation requirements and in quality and performance capabilities competes with the best western counterparts.


Quality control at all obstruction light ZOS-A production stages is carried out strictly in accordance with Specifications 27.40.39-004-28320930-2018, which enables to significantly decrease claims.


Function objective:


The medium intensity obstruction lights ZOS-A, type A, 20000cd are intended for high objects (obstructions) light marking, which pose dangers for air transport (high buildings and constructions, stacks, relay mobile communication masts, tower cranes, bridge pylons, any buildings in the vicinity of airfields).


The unique performance features of the medium intensity obstruction lights:


The obstruction lights operation and control is carried out over the communication line via RS-485 interface.


RS-485 is a physical level standard for the asynchronous interface which regulates electrical parameters of semi-duplex multipoint differential communication line, common bus type.

The reception and transmission in the bus is made asynchronously over UART in a semi-duplex mode with bit parity check.


The universal asynchronous receiver-transmitter (UART) is a computing node intended for setting up communication with other digital devices. It transforms the transmitted data into a successive type, so as it can be transmitted over one physical digital line to the other similar device.


Each obstruction light has a unique address, which is assigned in 1-100000 range. The address is assigned to the obstruction light by the manufacturer and remains the same during its operation. A user cannot change the address (serial number) of the obstruction light. 


   The unique optical unit provides compliance with ICAO and FAR requirements.

   The aluminum body with powerful radiator provides excellent heat removal.

   Vandal-proof design.

   Cree LEDs guarantee long service life.

   Practically, it does not require any maintenance.

   The service life is higher than that of the counterparts with a xenon light source.

   Lower power consumption compared to xenon counterparts, which provides safety for the                 specialists who mount them.

    Long-term cost-effective operation.


Solution advantages: 

   The obstruction lights ZOS-A are used as a separate unit or in the combination with the other             lights.

   The built-in status monitoring system enables to control the operation remotely not only of the           whole obstruction lights combination, but also a separate light.

   The status monitoring system of the obstruction lights in accordance with the standard ANSI             TIA/EIA-485-A:1998, Electrical Characteristics of Generators and Receivers for Use in Balanced         Digital Multipoint Systems.

   The obstruction lights flash synchronization with GPS.

Connection order:


The power, ground and control contacts are shown in figure 3.

The 46-48 V, DC, power cables (the polarity is mandatory) are connected to contacts + and - (see fig. 3).


The control and operation cables are connected to contacts CONTROL: where A and B are a control bus (twisted pair, RS 485 interface), which operates in the asynchronous semi-duplex mode. It provides commands reception and data transmission about light technical status; G- common cable; T- synchronization signal output.


In order to avoid short circuit, the cables A and B must not come into contact with each other as well as with the common cable G. To avoid conflict situations in the control line, the cables must be correctly connected to contacts A and B.


The ground wire is installed by the manufacturer and has an outlet on the obstruction light body.

The obstruction lights in the system operate according to the setup synchronization algorithm and technical parameters monitoring control.


The ground is connected to the central output. Wire cross-section is selected according to current consumption and it must not bigger than connectors 2,5 mm² size.


Complete set:

Main mounting and operation requirements:


The obstruction lights ZOS-A are mounted by a holder (a base stand) with outer G ¾ thread. The mounting base stands are installed on top of high objects (roofs, etc.), subject to light obstruction.

A stationary LED module is a light source in the obstructions lights ZOS-A, which do not require any service and replacement for the entire period of its operation.


So as to connect power and monitoring cables, you should unscrew the top part of the obstruction light (the light filter) from its base and then get them connected. While assembling the obstruction light, make sure that the rubber seal is tightly seated. You should brush the light filter with clean cotton, soft flannel or suede leather without using any solvent or grinding materials, if it gets dirty. Finally, you should clean it with spirits-soaked cotton.


Packaging:


The obstruction lights packaging according to GOST 23216 (All-Union State Standard) for storage conditions 2 (s) GOST 15150 (All-Union State Standard). The lights ZOS-A are packed in a shipping container, which secures safety and protection from any mechanical damage and atmospheric precipitation.


Labor safety rules:


To provide safety operating the obstruction light ZOS-A, it is prohibited:

  To replace the lamp for the light source with lower light intensity value;

  To carry out any operations with the obstruction lights with power on;

  To assemble or operate the obstruction light with damaged insulation;

  To assemble and operate the obstruction lights, it is required to follow PUE (Electrical Equipment

   Rules).
