Description

This section describes the ADB Airfield Solutions Signature Series.

Ferroresonant, L-828/L-829, constant current regulators (CCRs). These

CCRs are manufactured according FAA specification AC 150/5345-10F.

NOTE: Signature Series is a trademark of ADB Airfield Solutions.

See Figure 2-1. This subsection describes the L-828 CCR. The L-828

uses a Universal Regulator Controller (URC) to provide regulator and

control functions.

NOTE: Figure 2-1 shows a ferroresonant 15 kW/6.6 A L-828 CCR. The

other L-828 CCRs (4, 7.5, 10, 20-30 kW/6.6 A/20 A and 50/70kW) may

differ in size and appearance.

The L-828 CCRs are designed to

• supply three or five precision output current levels (6.6 A/20 A

maximum) to power airport series lighting circuits on runways and

taxiways.

• accurately regulate the output current to within ±1% of the adjustable

nominal levels from no load to full load and with input voltage

variations of -5% to +10% of nominal.

• maintain the nominal output current levels even when 30 percent of

the isolation transformers in the series lighting circuit supplied by the

regulator have open secondaries

See Figure 2-2. This subsection describes the L-829 CCR. The L-829

uses a URC to provide regulator and control functions. It also uses the

Advanced Control Equipment (ACE or ACE2) for control and

monitoring functions.

NOTE: Figure 2-2 shows a ferroresonant L-829 (15 kW/6.6 A) CCR.

The other L-829 CCRs (4, 7.5, 10, 20-30 kW/6.6 A/20 A & 50/70kW) may

differ in size and appearance.

See

Figure 2-3. This subsection describes the Switchgear Regulator Style

Powerpack. The SGRS Powerpack operates similar to the stand-alone type

L-828 / L-829 and uses a URC to provide regulator and control functions.

It also uses the Advanced Control Equipment (ACE or ACE2) for

control and monitoring functions.

The main difference is the CCR frame which is designed to insert into a

SGRS line-up.

NOTE:

829 CCRs (4, 7.5, 10, 15, 20 kW/6.6 A/20 A and 50/70kW) may differ in

size and appearance.

See Figure 2-4 below. The Universal Regulator Controller (URC) is a PC

board that is designed to provide all regulator and control functions for

ferroresonant L-828/L-829 CCRs manufactured by ADB Airfield

Solutions. This is accomplished with an 8-bit embedded microcontroller

and interface circuitry contained on a single 8 x 8 inch through-hole type

printed circuit board. The universal regulator controller PCB performs the

functions listed below.

• Produces SCR drive signals in accordance with the desired output

current setting.

• Detects an overcurrent, or open circuit, and switches the constant

current regulator off.

• When in Remote mode, enables the CCI to provide 120 Vac at 50 W.

The CCI is the Remote power control source.

See Figure 2-2 and picture below. The L-829 ACE (or ACE2) control and

monitoring unit consists of an integrated control unit that is interfaced to

each CCR either internally or within a small external enclosure. The ACE

printed circuit boards are mounted inside a small and rugged

environmental enclosure that is directly attached to the door of the L-829

CCR. The ACE consists of microprocessor-based module(s) that

processes communication, control commands, input/output interface, and

failsafe functionality for controlled elements in the airfield lighting vault.

Advanced Control Equipment (ACE) manual 96A0287 or the

The L-829 CCR monitoring options include the Insulation Resistance

Monitoring System (IRMS), Scanning Monitor Interface (SMI), and

Scanning Monitor Ready (SMR).

The IRMS is used only on the L-829. It performs scheduled cable

insulation resistance measurements and can also perform manually

requested measurements. IRMS provides the ability for monitoring the

long-term degradation of the airfield series circuit cabling and showing the

results on the L-829 CCR front display panel.

WARNING: When servicing a regulator equipped with an

IRMS module, be sure that power to the IRMS is disconnected

before touching the IRMS board, or any of

the high voltage components or wires.

The scanning monitor interface is a relay assembly that can be mounted

internally to the front panel of the CCR. The relay assembly consists of

four relays and sockets. The relay assembly is used to generate feedback

signals concerning the CCRs operation to the Remote Multiplexer. The

relay assembly generates feed back for the following signals: Remote/local

status, commanded ON status, regulator running status, and primary power

status.

The scanning monitor ready includes the scanning monitor interface plus

one current transformer (CT) and one potential transformer (PT). It also

has resistor loads, and a fuse in the potential transformer secondary.

Differential signals presenting the actual series circuit voltage and current

are transmitted to the scanning monitor system two-conductor shielded

cables.

The series cutout Type SCO is often used at airports having a large number

of series circuits to isolate the series circuit from the CCR during

maintenance or testing operations. It also allows manual measurement of

resistance of the series circuit to ground without disconnecting the series

cable. The SCO cutout has a nominal working voltage of 5 kV and a

nominal carrying current capacity of 20 amps AC.

This subsection describes the L-828 CCR theory of operation.

See Figure 2-5. A resonant network consisting of T1, C1, and the SCRs

draws from the input lines. This network is capable of drawing a limited

amount of power. It can be routed to one of two places. The first is the

output leads to the airfield. The second is a resonant tank comprised of C1

and part of T1.

As more power is allowed to flow into the resonant tank, less is available

to flow to the field. It is by regulating the current in this tank that the

SCRs regulate throughput current to the airfield. It is important to note

that the output of the regulator will be the smallest when the “SCRs” are

conducting 100% of the time. This is the opposite of what is seen in

simple SCR regulators where the SCRs are used to directly control the

output of the regulator.

NOTE: C1 is actually a bank of capacitors located near T1.

The components of the resonant network are designed to deliver an output

current slightly higher than 6.6 A/20 A for the minimum input voltage,

while the SCRs are fully off.

The output current flows through the high voltage current transformer T5.

T5 provides feedback to the URC board on the actual current output to the

airfield series circuit.

A second current transformer, T2, provides current to a true rms-reading

ammeter mounted onto the front panel to indicate output current.

See Figure 2-4. This subsection describes the board level circuitry found

on the universal regulator controller.
