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 light fixtures 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.

PROGRAMMING SAFELED IQ
SafeLED IQ can be delivered as a pre-programmed unit with field position information
and monitor/control parameter settings.
The SafeLED IQ can also be programmed during maintenance or updated remotely
from the sub-station if installed in a circuit using the Wake on Circuit function.
3.2.1
Setting up the Hardware Equipment
The following hardware is required for SafeLED IQ programming:
SCM
– Series Circuit Modem.
LPC
– SafeLED IQ/Sensor Interface Unit (SIU) Programming Control unit.
Cable(s)
– power and communication.
PC
– including ASP-SC Maintenance Tool (AMT) software for programming.
The following are instructions how to set up the hardware equipment required for
SafeLED IQ programming.
Connect the LPC unit to SCM unit
FIGURE 34
– HW SETUP FOR PROGRAMMING
1. Check the voltage selector is in the appropriate position: 120 or 240 V.
2. Connect the LPC unit to the SCM unit using the cables supplied.
Connections are made at the rear of each unit.
