3.0 Introduction
This section describes the L-827/ L-829 Advanced Control Equipment (ACE2™).
Note
ACE and ACE2 are trademarks of ADB Airfield Solutions.
The ACE2 operates either as the remote interface between the L-890 ALCMS and any controlled element in the airfield
lighting vault or as the stand-alone regulator/monitor performing all L-827/L-829 functions in accordance with FAA AC 150 /
5345-10F. The ACE2 is a universal device that can be used to control any type of CCR and/or controlled element regardless of
the manufacturer.
L-827/L-829 ACE2
The ACE2 can be physically packaged as a Combo Box-Mount (Figure 3), a Wall-Mount (Figure 1), or a CCR Internal-Mount
(Figure 2). The Combo Box Assembly is a wall-mount version, which houses the ACE2 controller board, the IRMS board, and
the CVM. The Remote-Mount is typically placed on top of the CCR. The Wall-Mount is usually bolted to a wall or can be
mounted on the front of a CCR. The internal-mount is mounted inside a ADB Airfield Solutions L-828 CCR. This combination is
called an L-829 CCR.
3.1 Advanced Control Equipment
Compliance with Standards
FAA: Monitoring: Certified to AC 150/5345-10 (Current Edition). ETL Certified.
Insulation Resistance: AC 150/5340-26 Chapter 3, Section 2, para. 27.
Overview
The ACE2 can operate either as the remote interface between the L-890 ALCMS and any controlled element in the airfield
lighting vault or as the stand-alone constant current regulator (CCR) monitor, performing all L-827/L-829 functions in
accordance with FAA AC 150 /5345-10. The ACE2 is a universal device that can be used to control any type of CCR and/or
controlled element regardless of the manufacturer.
The ACE2 can be packaged as a remote mount, wall mount, CCR internal mount, or Combo Box. A remote mount is typically
placed on top of the CCR. The wall mount is typically bolted to a wall or can be mounted on the front of a CCR. The internal
mount is mounted inside a ADB Safegate L-828 CCR (Also called a L-829 CCR). The Combo Box Assembly is a wall-mount
version, which houses the ACE controller board. The Combo Box Assembly also houses the IRMS board and the CVM, which
are normally mounted inside a ADB Safegate L-829 CCR.
Each CCR and controllable item is connected to an ACE2. The ACE2 is a microprocessor-based module that includes all of the
communication, control commands, input/output inter-face, and fail-safe functionality for the controlled element.
Note
For those applications that require:
•Connection with up to a four-circuit L-847
•Up to eight discrete input or outputs
Use ADB SAFEGATE's first generation ACE system. Request data sheet 2016 for more information.

Theory of Operation
The Advanced Control Equipment (ACE2™) represents the heart of ADB SAFEGATE's airfield lighting distributed control
system. Distributed control technology has many advantages over traditional central control, including but not limited to:
cost-effectiveness, system expandability, ease of maintenance, ease of installation, interchangeable parts, and ease of
troubleshooting. In a distributed control scenario, each ACE2 unit is locally installed at or near a controllable item (CCR,
Generator, ATS, etc.). Each ACE2 would, in turn, talk with the airfield lighting control network and execute remote lighting
commands. Multiple ACE2 units can be daisy-chained together, making system expansion very easy.
The ACE2 is a universal device that can be used to control any type of CCR and/or controlled element regardless of the
manufacturer. The printed circuit boards are mounted inside a small and rugged environmental enclosure that can be
mounted on top of the CCR, wall mounted or directly attached to the door of an ADB Safegate L-828 CCR.
The ACE2 consists of a microprocessor-based module(s) that includes all of the communication, control commands, input/
output interface, and fail-safe functionality for the controlled element.
The ACE2 is ADB SAFEGATE' second generation distributed control/monitor system. ACE2 network communications are
compatible with ADB SAFEGATE's first generation system simply called ACE. Thus ACE and ACE2 units can be connected on
the same distributed network.
Communication
Each of the ACE2 units connected to a CCR or other controllable device will have a unique factory set number and a field
programmable communication address. This address is used by the ADB SAFEGATE L-890 ALCMS to direct lighting
commands to the corresponding ACE2, which in turn executes the commands and returns the operational status of the
element back to the ALCMS.
Each ACE2 is connected to redundant communication networks via two RS-422 serial communication ports located on the
main printed circuit board. The ACE network is comprised of a communications server and all the daisy-chained ACE2 and
ACE (if present) units in the lighting vault. Both the ACE2 and ACE devices can be connected to the same network. The
communications server stays in constant communication with all the ACE2 and ACE units in both of the networks while at the
same time staying in constant contact with the main ALCMS network. This communications protocol dictates that the local
ACE2 store all data and parameters specific to the controlled element. This characteristic frees up the ALCMS computers from
having to store the parameters for each of the controlled elements. The result of this is real-time communication between all
of the ACE2 and ACE units and the rest of the ADB SAFEGATE L-890 ALCMS, even if a network connection fails in one of the
ACE2 or ACE units.
Input/Output Interface
The ACE2 incorporates an input/output interface that supports full FAA L-827/L-829 CCR control monitoring capabilities. The
pluggable terminal blocks provide an easy-to-service point of connection.
The latching output relays can be configured to control CCR brightness steps or simple ON/OFF control as required by the
controlled element. The input lines can be configured to monitor any external event that is determined by a discrete dry
contact closure. Some examples include generator monitoring, monitoring of Automatic Transfer Switch position, and control
of Circuit Selector Switch loops. In addition, the ACE2 can be optionally expanded to perform CCR input voltage and current
monitoring as well as airfield circuit cable Insulation Resistance Monitoring.
Fail-safe Functionality
Each ACE2 unit provides a self-contained fail-safe feature. This feature insures default airfield lighting operation in the event
of an L-890 ALCMS component failure or even a complete ALCMS failure. In addition, each ACE2 can monitor its output and
verify that the proper command is executed. The fail-safe system also permits maintenance of portions of the control system
without changing the operational status of the lighting system. The fail-safe system is by definition only used in the ALCMS
modes, and must be set up by a qualified ADB SAFEGATE technician.
The fail-safe mode of each ACE2 unit is defined per requirements of the airport/owner. The fail-safe modes are as follows:
Latching Fail-safe Mode:
This mode is executed as follows:
•If the CCR was switched ON before the failure, it will remain ON at the same brightness level.
•If the CCR was switched OFF before the failure, it will remain OFF.
Simple Fail-safe Mode:
Advanced Control Equipment (ACE2)
Introduction

Copyright © ADB Safegate, All Rights Reserved

This mode is executed as follows:
•After a failure occurs, the CCR will switch ON to a predeter-mined brightness level without regard to the current step.
Smart Fail-safe Mode:
This mode is executed as follows:
•If the CCR was switched ON before the failure, it will remain ON at the same brightness level.
•If the CCR was switched OFF before the failure, it will switch ON to a predetermined brightness level.
Graphics User Interface (GUI)
The ACE2 graphic user interface (GUI) consists of the 128 x 64 pixel monochrome LCD display and four momentary switch
buttons. In typical modes of operation, the upper half of the LCD displays a monitored parameter or in the stand-alone mode
a configuration menu. The first string of the LCD lower half is reserved for warning and alarm messages in “reverse color”.
Reverse color means that the background is white and the text is blue. The second string is split to indicate several fields and
displays:
•Brightness step. Reverse color means protective shutdown, blank – OFF.
•Remote (“Rmt”)/Local (“Lcl” reverse color)
•Primary power present (“PP”) / loss of power (“LoP” reverse color)
•RS422 channel A message received ('A')
•RS422 channel B message received ('B')
•IRMS response received (small 'W'), megging has been reported (large 'W')

3.5 Main Circuit Board
The Main Printed Circuit Board (Figure 4) is the central part of the design. It includes a micro-controller core that implements
main logic and provides calculating functions. A communication circuit provides the interface for the redundant
communication network (RCN), which is how ACE2 receives and transmits data to the ALCMS vault computer. It contains a
fiber optic interface connection for the Current Voltage Monitor (CVM), optional Insulation Resistance Monitoring System
(IRMS), and an RS-232 local configuration interface. The watchdog jumper (J2) is used to select whether the watchdog timer is
On or Off. Connecting pins 1 and 2 enables the watchdog timer. Connecting pins 2 and 3 disables watchdog timer, and
removing the jumper also disables watchdog timer. The normal setting for the watchdog timer is On. The watchdog timer
should only be set by qualified ADB Airfield Solutions personnel. The reset switch (SW1) is used during the design and test
phase, and has no application for the user. The keypad switches and an LCD connector provides a Graphic User Interface (GUI)
for local control and monitoring for all controllable functions. The display is connected to the main board by a ribbon cable.
The two-position DIP switch (SW2), is not currently used, but allows for future upgrades. The DIP switch must remain with
both selectors in the On position for proper operation. The Power Supply circuitry provides all ACE2 equipment with a
regulated and isolated power source.

The Discrete Input/Output circuitry provides an interface for all control and monitoring connections. It contains seven latching
relay outputs and, one proper operation, mono-stable relay output normally used for the Fault Alarm indication. The I/O
circuit contains eight Optically-isolated input lines.
3.6 ACE2 Lamps-Out Monitoring Board
The ACE2 lamps-out monitoring (LOM) board (Figure 5) consists of a processor communicating over a fiber optic serial
communications link, with up to three Current and Voltage Modules (CVM). In addition to RMS voltage, RMS current,
apparent power (VA), and true power (WATTS), the LOM Board also calculates the number of lamps burned out at each
brightness level. The Lamps-out function can detect up to 16 burned out lamps.
If the CCR is controlling multiple circuits through circuit selectors, each of the circuits may have a CVM monitoring voltage,
current, watts, VA, and the number of lamps out on the circuit.
The setting of the two-position DIP switch (SW1) depends on the number of circuits monitored and the number of Lamps-Out
boards used. If the ACE2 contains only one Lamps- Out board, the settings are:
•Switch 1 - Off
•Switch 2 - Off
If the ACE2 contains a second Lamps-Out board, the SW1 settings on the second board are:
•Switch 1 - Off
•Switch 2 - On
If the ACE2 contains a third Lamps-Out board, the SW1 settings on the third board are
•Switch 1 - Off
•Switch 2 - On
The third Lamps-Out board also has a 4-port jumper with a jumper on pins 1 and 2.

Note
VA refers to the Volt-Amps in an airfield load and is measured by reading the RMS voltage, measuring the RMS
current, and multiplying these two numbers together.
Watts corresponds to the amount of power actually consumed by an airfield load. These two numbers are only equal in the
case of a purely resistive load. In systems with reactance (capacitance or inductance), power from the source enters the
reactive portions of the load, and returns to the source, un-used. This additional unused energy is the difference between the
VA and Watts delivered to a system. The power factor of a load is the ratio of the power (watts) used by a load, to the volts
and amps (VA) that are delivered to the load. This is always less than or equal to 1.
It is important to remember that all electrical components in a power system are designed to deliver the necessary VA the
system needs in order for it to consume the watts it needs.
CCR sizes are actually designed to deliver a kVA value because it is impossible to account for the different power factors in
airfield loads. If an airfield load has open-circuited transformers, signs, etc. it requires more VA to deliver the watts needed.
For instance, if a 30kW CCR delivered 30kVA into a load with a power factor of 0.5 the resultant watts would be 15kW.
