2.2.3.1 AGLAS Technology

•

Communicates using a radio frequency signal imposed on the high- voltage airfield series circuit cable - no separate

communication cable needed.

• Communication quality is automatically optimized for each series circuit in a permanent background process.

• New communication principle together with forward error correction drastically reduces signal disturbance caused by impulse

and narrow band interferences.

• Main system elements: AGLAS Master (in the substation), AGLAS Remotes (for individual control and monitoring of lights in

the field). In addition, AGLAS Utility Remote for communication with and energy supply for local field sensors.

2.2.4 Checking the Device

2.2.4.1 Scope of Supply

AGCXXXX Master is supplied with four 19” (0.5m) long cord-set cables for connection to the high-voltage lines from the series

circuits, and includes an instruction manual.

2.2.4.2 Unpacking

The device has been fully assembled, tested and packed at the factory and has no internal transport locks.

NOTE: In case of significant differences in temperature between the means of transport and the place where the device is to be

unpacked, it is recommended to leave the device in its packaging for acclimatization, in order to avoid damage from

condensation.

(e.g. 12 hours for a 30°F (20°C) temperature difference, longer with greater differences.

2.2.4.3 Inspection

The delivery must be checked to make sure that it is complete and in perfect condition. The supplier must be notified of any

complaints within 2 weeks. After this period, complaints about the delivery will not be accepted. In the event of the goods being

returned, the same transport packaging must be used. The number on the nameplate must be checked against the order number

on the delivery note. The nameplate, Figure 2 is located on the side of the device (example: AGLAS Master 30kVA).

Figure 2: Nameplate of the AGLAS Master

The address (MAC ID) of the Ethernet interface Eth0 and Eth1 (e.g. Eth1 Address 0009CF8A 01D9, see illustration) should be

recorded and will be utilized during commissioning. Found on the ABOUT screen.

2.2.5 Storage

If the AGLAS Master has to be stored for a longer period between receipt and installation, it is recommended to leave the device

in its transport packaging.

If the AGLAS Master has to be stored without its packaging, it must be stored in a clean, dry location in order to prevent

contamination via the ventilation slots in the top cover plate.

The storage temperature is shown in “Technical Specifications” on page 27.

NOTE: Allow the AGLAS Master to acclimatize prior to installation for 12 hours before switching on power and the high voltage in

the series circuit.

* Contact ADB Safegate for support

** Technical requirement, not excluding ICAO /FAA compliance

2.3 Theory of Operation

Background Information: AGLAS uses power line carrier (PLC) technology to communicate between controlling units on an airfield

lighting series circuit. A AGLAS system typically consists of one high voltage modem, or Master, collocated with the Constant

Current Regulator (CCR) powering the airfield lighting circuit and many slave units, or Remotes, collocated with individual lights in

the field. A typical AGLAS topology is provided in Figure 6.

• Up to 20 km round-trip circuit length.

• Configurable block evaluation modes include full feedback, small sample feedback, and optimistic feedback.

• Can command 10 blocks to 10 distinct states with one powerline message. Can command all blocks to one state with one

powerline message.

• Switches up to 600 lights, in 10 different groups, in less than 1 second.

• Switches 5 stopbar/lead-on lights simultaneously and presents real-back indication in less than 1 second.

• Status poll provides detailed Remote and lamp parameters.

2.3.2 Integrated System Control

Overall system configuration and control is realized via a control process with integrated web server for configuration and

maintenance.

• Each circuit is equipped with a microprocessor-controlled Master for tracking, recording and management of state of all

Remotes in the circuit.

• The Master communicates with all the Remotes (not light fixtures) in a circuit and polls all lamps independent from the control

system.

2.3.3 Architecture

Figure 7 depicts the general nature of the system components and their interactions. The “Control System”, shown in grey, is an

external ALCMS system that provides controlling commands and digests Master and Fixture status reports. There is typically only

one control system in the architecture. The “Master”, shown in blue, is the high voltage modem that communicates commands to

and receives status from the fixtures. There can be many masters in a given system. Masters digest commands from the control

system and provide status to it. Masters also communicate amongst themselves to maintain communication timing

synchronization. Each master communicates with the fixtures on its respective circuit.

2.4 Installation of stand-alone AGLAS Masters

2.4.1 Installation in the Control Cabinet

NOTE: The AGLAS Master is designed for protection class IP 20 (NEMA 1) according to IEC 529 and is approved for contamination

grade 1 according to IEC 60 664-1 (operation in dry air-conditioned spaces).

The environmental conditions are defined in “Technical Specifications” on page 27.

The airflow is from front to back through the AGLAS units so ensure there is ample room behind the units for proper cooling and

air flow.

The devices should be mounted on rails, brackets or tilting racks. They are to be fixed with the 4 clamp bolts positioned on the

front.

The ground cables of the AGLAS Masters must be connected to the bus bar in the electrical cabinet.

The control cabinet bus bar must be connected by a wire with a minimum cross-sectional area of AWG 0 (50mm

) to the central

earth ground in the control room.

2.4.1.1 Power Supply

The power cable (18 AWG (0.75mm

) recommended) is to be provided by the user. The plug supplied is to be attached to the

cable. The cable is used to connect the mains socket POWER at the rear of the AGLAS Master to the cabinet power supply.

Each AGLAS Master must be individually fused with a 10 A circuit breaker.

(For the location of the power socket, refer to “Rear View with Connections” on page 11).

2.4.1.2 Connection to the Series Circuit

The high-voltage connections “FIELD” and “CCR” on the AGLAS Master are each pre-prepared with cables with a length of 19-in

(0.5m), in accordance with the FAA L-824 specification.

The plugs on the built-in cables “CCR” are connected to the sockets on the extension cables going to the CCR. The latter have to

be separated in the middle beforehand. The extension cables must be shortened to the appropriate length and mounted on the

cabinet terminal strip. From there the connection to the Constant current regulator is made.

The connections from the control cabinet to the Constant current regulator are to be established on site.

The sockets on the built-in cables “FIELD” are connected with the plugs on the extension cables. The free ends of these extension

cables are to be shortened to the appropriate length and mounted on the cabinet terminal strip. From there the connection is

established to the series circuit cables, which lead to the airfield.

(For the location of the series circuit connectors: refer to “Rear View with Connections” on page 11).

2.4.1.3 Over-voltage Protection

When installed on a CCR of 20kW or greater, the CCR contactor wiring shall be run through the AGLAS over-voltage contactor.

Shown in Figure 5.
