6.0 Operation
This section describe the different technologies that enable the operation of the RGL-E light and instructions regarding
programming and connection of the light. Before you start, make sure you have read and understand Safety instructions .
6.1 Technology description
6.1.1 ASP Safecontrol System Technology
A Safegate ASP-SC system is designed to provide individual monitoring of airfield lighting using the series circuit as a means
of communicating status information from airfield lights and sensors. The same concept is used for lighting control providing
the foundation for SMGCS or A-SMGCS, which includes for example automation of stop bars with or without sensors, taxiway
guidance (routing) in combination with status monitoring. For more information, see ASP-SafeControl documentation.
6.1.2 SafeLED IQ and the 2A Concept
The ASP-SC System, using the IQ concept, is designed to provide selective switching and/or monitoring of airfield lighting by
use of an addressable switching unit inside each individually controlled light. A SafeLED IQ light is connected to the
secondary side of a standard series circuit isolation transformer. Communications to/from a SafeLED IQ light uses a unique
power line communication technique developed by Safegate Group where the communication signals are superimposed on
the series circuit current.
In a 2A system the CCR is set at a low constant current and the ASP-SafeControl manages the intensity level of every single
SafeLED IQ light fixture. Furthermore the SafeLED IQ light fixtures can have different light intensity levels in the same circuit.
6.1.3 Sensor Interface Unit (SIU)
Sensors for presence- and direction detection of aircraft and vehicles on the airfield can easily be interfaced to the ASP-SC
system using a SIU. The SIU communicates the detect/no-detect status signals as well as its own status to the series circuit in
the same manner as the SafeLED IQ. The SIU is also connected to the secondary side of a standard isolation transformer using
a standard 2-pin FAA-style connector. Connection to the sensor is established using an IP68 rated 7-pin connector. The SIU
can also supply the sensor with DC-voltage from a built-in current to voltage converter.
6.1.4 Network Concentrator Unit (NCU)
The NCU concentrates all incoming status information from the field, both lamp and sensor statuses. The NCU includes
redundant capability.
6.1.5 Series Circuit Modem (SCM)
The SCM is an interface to the series circuit which receives command from an NCU. The SCM connects to the series circuit via
a standard isolation transformer and to an NCU via standard RS485 or RS232 serial communication.
6.1.6 Series Circuit Filter (SCF)
The SCF is connected across the Constant Current Regulator (CCR) series circuit output and is used to contain the
communication signalling within the airfield circuit and minimize feedback into the regulator.
6.1.7 Control System Interface
The NCU operates as the ASP-SC system main interface interpreting commands sent from the Host/Supervisor System
(including the Safegate ASP-SC system) and in turn controlling the appropriate SafeLED IQ as directed. It maintains all lighting
and error status, sensor detections as reported from the airfield components and is the central point of the ASP-SC system as
operated from each vault. Individual lights can be grouped in lighting segments spanning one or more series circuits, for
example an interleaved stop bar. In turn, the NCU provides alarm status for percentage and adjacent lamp failure within those
defined lighting segments per requirements for low visibility operations. Airfield lighting and ASP-SC system component
status are constantly monitored and updated to the Host/Supervisor system upon occurrence.
6.2 Programming SafeLED IQ
SafeLED IQ is delivered as a pre-programmed unit with field position information and monitor/control parameter settings.
