Страница: 20 / 118

Four different types of remotes have been designed to allow the user to handle all possible kinds of lighting control:
•
SRU101: to control lights with one beam direction
•
SRU102: to control lights with two independent beam directions and only one secondary transformer connected
•
SRU111: to control lights with one beam direction, with redundant voltage limiting circuits to act as a part of a SELV
configurated series circuit.
•
SRU112: to control lights with two independent beam directions and only one secondary transformer connected, with
redundant voltage limiting circuits to act as a part of a “SELV” configurated series circuit
Specific configurations for different lights switched in series by only one remote are also possible, as RELIANCE IL is
available with a 300 W output. Using the parameterizing software lucDMC, individual control and monitoring numbers
(addresses), communication parameters and segment numbers are assigned to the remotes via the series circuit line. The
parameterization can also be done with the RFID reader DRH100.
A blink feature can be set optionally. The blink feature is used for RGLs or Runway Holding Position Lights (RHPL).
Communicating with the CUs, a centralized synchronization of the blink features of all remotes in a series circuit can also
be established optionally.
No manual adaptions or long-termed commissioning for the individual circuits are necessary, as the settings are
programmed to be overtaken automatically every time the series circuit is switched on.
2.4 Functional description
The ADB SAFEGATE RELIANCE IL is a successor product of the COSAL SCROLL ILCMS system. RELIANCE IL allows the user to
control and monitor individual lights in a constant current driven lighting series circuit. Individual lights or segments can be
switched separately in a series circuit. This feature makes it possible to map an entire runway and / or taxiway or to group
switchable stop bars with a common power supply. The system is designed to build up fail-safe airfield ground lighting
systems. The RELIANCE IL SRU remotes serve to monitor every single light within a series circuit. RELIANCE IL (known in the
industry as an ILCMS) form the basis of a dynamic runway map for lighting and precise monitoring, including detection of
failures in neighboring components as required in ICAO Annex 14. The circuit is steerable phased, based on a thyristor and
achieves Root Mean Square (RMS) currents of 1.6 to 6.6 Amperes (0.1 to 100 % light intensity).
The Airfield Ground Lighting Control and Monitoring System (ALCMS) processes control commands sent by Air Traffic Control
(ATC) panels or Aviation Safety Monitoring System (ASMS) (e. g. radar monitoring) and decrypts the commands into logical
lights segments and physical (often redundant) sections of a lighting circuits or single lights.
The lamp output is cut out by a electronic component when it receives a valid OFF command by the remote to force the
series current to bypass the load. The bypass results in the lamp being switched off. The CCR is to be set completely OFF if all
lights are supposed to be off. This action is meant to save energy.
In the opposite way, the bypass of the lamp is opened and the current flows through the lamp filament when the electronic
component receives a valid ON command from the remote. The light switches ON. The outlet is bypassed when a overvoltage
was measured at the lamp outlet. This way, high voltages at the lamp outlets are avoided.
Testing of the connected lamps is supposed to be executed cyclically with ON and OFF states in a cycle that is to be defined.
Lamp test commands for sending the test results are fed into the series circuit automatically and cyclically when there are no
detected commands.
The CU is installed into a slot of the CCR and monitors the data flow in the series circuit.
The CU listens the sensor line of the CCR and demodulates and filters the control commands. The CU also filters feedback
created by the CCR and the remotes out of the series circuit marked by harmonic content. The CU forwards the calculated
results to the Communication Unit of the CCR that is connected to the ALCMS.
CCR automatically resends the command when a faulty command is detected on the circuit line. This action is intended to
guarantee a high level of reliability and reaction speed in case of a faulty command.
A special characteristic is that the CCR reduces the current synchronically to the control command if more than a defined
percentage of the lights — relative to the dimensioning of the circuit and the number of lights that stay ON — must be
switched off simultaneously to protect the circuit from overvoltages with damaging effects.
