1.2
EQUIPMENT DESCRIPTION
1.2.1
Features
The Constant Current Regulator is a power supply designed for precision operation of
airfield lighting. The output current is regulated within +/-1% at any load and for
line voltages form +10% to -5% of nominal. The three or five discrete brightness steps
conform to FAA standards. The regulator may be controlled both locally and from a
remote location.
Protective circuits are provided to sense an overcurrent or an open circuit in the
series lighting loop and shutdown the regulator. The front panel display alerts
maintenance personnel to the nature of the shutdown. The protective circuitry can
be reset by setting the regulator control switch to off for 1 second. Provided no fault
condition remains, setting the control switch to the desired brightness step will
restore operation.
The regulator may be connected directly to an FAA approved load switching device.
No regulator malfunction or damage to the series lighting loop will occur.
1.2.2
Options
This regulator can be factory supplied with various options. Contact Crouse-Hinds
Airport Lighting Products for a current list of options.

SECTION 2. TECHNICAL DESCRIPTION
2.1
THEORY OF OPERATION (BASIC REGULATOR)
The information presented here applies to a standard model Constant Current
Regulator (CCR). Regulators supplied with options may have minor operating
differences, but the basic operation is the same for all units.
Many functions in the CCR are controlled by a custom programmed electronic circuit.
This device performs brightness step and digital display control, open circuit and
over-current sensing, and handles system fault conditions. Several optional features
also use the programmed circuit to reduce the amount of additional circuitry
required. Each of the standard functions is discussed in detail in the following
paragraphs. Optional functions are discussed in Supplemental sections of this
manual.
2.1.1
Current Regulation
A ferro-resonant transformer is conjunction with a pair of silicon controlled rectifiers
(SCR) is used for current regulation. This design provides precise control regardless
of the load size or line voltage. For very low loads or low brightness settings, the SCR
conduction angle will be large. At increased loads or higher brightness settings, the
conduction angle will be smaller.
The SCR gating signal is controlled using closed-loop electronic feedback control.
Load current is sensed by a current transformer which generates an analog signal.
The signal is processed by an electronic circuit and compared to a predetermined
reference. The result is a time delayed SCR control signal. This control signal is
applied to a pulse transformer to generate a gating signal for the SCR’s.
2.1.2
Brightness Control
Each brightness step has a specific digital reference value stored in electronic
memory. When the desired step is selected on the keypad, the proper memory value
is converted to an analog signal. This signal is the reference used for comparison as
discussed in paragraph 2.1.1. Refer to Section 3.2 for keypad operation. All remote
brightness connections are electrically isolated form the control electronics by optocouplers for transient protection.
5
9540
Rev. W
2.1.3
Remote Control Operation
The regulator can operate remotely using external switches connected to the remote
control terminal block TB1. The exact wiring of these switches depends upon
whether control power is obtained from the regulator internal supply or from an
external source.
The regulator turns on to brightness B1 (or B10) when control power is applied to
terminals CC and B1 (B10). To get a higher brightness, control power is applied to
terminal B2, B3, B4 or B5. (For three-step regulators, apply control power to B30 or
B100, for one-step regulators, apply control power to on). Only the terminal for the
desired step and CC require control power. If two or more steps are energized
together, the regulator will operate at the highest brightness step selected.
2.1.4
Digital Display
A multi-purpose Digital Display provides system operation data. Under normal
conditions, the display shows the output current being supplied by the CCR. Under
power-up and system fault conditions, it displays specific CCR status data (refer to
paragraph 2.1.6).
2.1.5
Protective System
2.1.5.1
Overcurrent Protection
Overcurrent protection is triggered by comparison of the value of the feedback signal
to predetermined limits. In the event of a minor overcurrent (between 5% and 25%
above rated output), the control system responds within 5 seconds. If a major
overcurrent (greater than 25% above rated output) occurs, the control system
responds immediately. The response consists of de-energizing the load by opening
the main contactor and providing status data to the digital display. To reset and reenergize the CCR, the keypad or remote brightness control switch must be set to OFF
for at least one second.
2.1.5.2
Open-Circuited Load Protection
This protection is triggered by comparison of the value of the feedback signal to a
minimum current level. If the current remains below 2 amps for about 1 second, the
control system performs the same shutdown sequence as for overcurrent protection.

2.1.5.3
2.1.5.4
Fuses
There are two fuses in the regulator for internal power supply protection. Fuse F1
protects the internal 120 VAC supply. Fuse F2 protects the remote control system
supply.
2.1.5.5
Transient Protection
Protection against transients from lightning or other sources is provided. Lightning
arrester LA1 protects the regulator power lines. Arresters LA2 and LA3 protect the
regulator load lines. Varistors are provided on the control system assembly to protect
it from transients on the power and control lines.
The lightning protection provided exceeds the requirements of the applicable Advisory
Circular. Lightning is a naturally occurring phenomenon that varies in intensity and
frequency based upon geographic location. Therefore, each installation should be
evaluated to determine the need for additional lightning protection.
2.1.6
System Status Information
The CCR Digital Display is used during power-up and fault conditions to provide data
regarding system status.
2.1.6.1
Power-Up
When power is applied to the CCR and when resetting from a latched fault mode, the
control electronics performs a series of internal checks. If these are completed
without incident, the control program number will be displayed for one second. The
display will then begin to indicate CCR output current. If any check is not
successfully completed, the system will "lock-up" preventing further operation.
2.1.6.2
Fault Status Messages
If the CCR control circuits detect an abnormal system shutdown, a message will
automatically scroll across the display. When two or more fault conditions exist, the
most recent occurrence is displayed. Messages are cleared when the system is reset
or conditions return to normal. Refer to the Operation and Maintenance Sections for
information on specific messages.

2.1.7
Monitoring (L-829 Only)
The monitor circuitry utilizes runway circuit and regulator signals to perform its
function. The runway circuit current and voltage are applied to current and potential
transformers which perform isolation and step-down functions. The outputs of these
transformers are applied to the electronic circuitry for processing. Also, the regulator
brightness step signals are used by the monitor circuit.
2.1.7.1
Calibration (L-829 Only)
The calibration function is used to initialize the monitor. Upon selection of this mode,
the operator is prompted for information on the specific load circuit and the desired
alarm levels. When all the information has been entered, the monitor turns on the
regulator and automatically adjusts itself for each brightness step. When this
adjustment period is completed (usually within 2 minutes), the regulator is returned
to the off state.
2.1.7.2
Normal Operation (L-829 Only)
The monitor continuously checks the runway circuit for faults. If no system faults
have been detected, the monitor relay is in the energized state, the lampout warning
and alarm relays are in the de-energized state, and the digital display functions as a
true-RMS ammeter.
2.1.7.3
Regulator Power Fault (L-829 Only)
Any removal of input power will de-energize the monitor relay immediately, thereby
signaling a regulator fault.
2.1.7.4
Protective Circuit Faults
In the event of an open circuit or overcurrent shutdown (see section 2.1.5), the
monitor relay will be de-energized, signaling a regulator fault. In addition, the display
will indicate what fault was encountered.
2.1.7.5
Brightness Step Fault (L-829 Only)
The monitor continuously checks the load current. This current value is compared
with reference values selected by information from the brightness step control inputs.
If the fault is continuously present for a five second period, the monitor relay is deenergized. A star (*) will appear to the right of the current reading on the digital
display to indicate an alarm. This fault condition will reset when (1) the current
returns to an in-tolerance value, (2) another properly operating brightness step is
selected, (3) the regulator is set to the off position.
8
9540
Rev. W
2.1.7.6
Ten Percent Drop in Load Volt-Amperes (L-829 Only)
When a large change in load volt-amperes occurs, it is an indication that there are
either two ground paths in the runway circuit or that there are many lamp burned
out in the circuit. After a five second delay, the monitor relay is energized and a star
(*) appears on the digital display to indicate an alarm. The fault condition remains
until the situation is corrected. Connection of a runway circuit selector between the
monitor and the loads will affect monitor performance.
2.1.7.7
Lamp Failure Detection (L-829 Only)
The lamp failure detection feature of the monitor is performed in essentially the same
manner as the monitoring of volt-amperes discussed in paragraph 2.1.7.6. It is
important to note that because of the method used to detect lampouts, it is not
necessary to eliminate lamp shorting devices commonly used in some lighting
circuits. If the number of lampouts exceeds the warning level entered by the user, the
lampout warning relay will energize. If the number of lampouts exceed the alarm
level entered by the user, the lampout alarm relay will energize as well, and the
monitor relay will de-energize.
2.1.8
Elapsed Time Meter
The regulator is equipped with an electronic elapsed time meter. It records the total
on-time of the regulator as well as the individual brightness steps. It will record up to
9999.9 hours of operation before starting at zero hours again. It can be viewed by
entering the appropriate command at the regulator keypad. The total or individual
brightness step on-time may be viewed while the regulator is in the on or off state.

OPERATION
Figure 3-2 shows the standard controls and indicators on the front control panel.
3.2.1
Local Control Keypad
The local control keypad in conjunction with the digital display acts as an interactive
control terminal for entering many different operational commands into the regulator.
All keypad entries are echoed to the display for a period of five seconds for operator
verification. In all instances, with two exceptions, the command sequence ends with
the “E” key ( for Enter). The two exceptions are the “ABORT” command - which
erases any un-entered command, and the “OFF” command - which will immediately
turn off the regulator.
To select an operating brightness step, simply press the keys according to the
following list:
(Remember - If you make a mistake, press “A” for ABORT.)
To select OFF -
Press “OFF” (no Enter required)
or
Press “BO (Enter)”
or
Press “0 (Enter)”
To select Remote -
Press “BB (Enter)”
For 1 step regulators:
To select ON -
Press “B1 (Enter)”
For 3 step regulators:
To select B10 -
Press “B10 (Enter)”
or
Press “B1 (Enter)”
To select B30 -
Press “B30 (Enter)”
or
Press “B2 (Enter)”
To select B100 -
Press “B100 (Enter)”
or
Press “B3 (Enter)”
Entering B4 or B5 will result in an “ERROR” message.
14

Rev. W
For 5 step regulators:
To select B1 -
Press “B1 (Enter)”
To select B2 -
Press “B2 (Enter)”
To select B3 -
Press “B3 (Enter)”
To select B4 -
Press “B4 (Enter)”
To select B5 -
Press “B5 (Enter)”
Entering B10, B30 or B100 will result in an “ERROR” message.
The brightness step command is stored in what is called ‘non-volatile’ electronic
memory which is reliable for at least 10 years without power applied. This enables
the regulator to immediately return to the selected brightness after a power
interruption without operator intervention - just as if a rotary switch were used for
brightness control.
3.2.2
Digital Display
During normal operation, the digital display functions as a True RMS ammeter,
displaying the regulator load current.
during power-up, under system fault
conditions and when the keypad is in use, the display performs other functions.
When these other functions are finished using the display, it automatically returns to
reading load current. If the display is echoing keypad entries and no new entry is
made within 5 seconds, the display returns to reading load current. They key entries
are not lost.
When power is initially applied to the regulator, the computer performs checks for
valid operation. If these checks are completed successfully, the display will read
“VER. X.X.”, where X.X is the software program version number, for a period of 1
second. Then normal display activity will begin.
If the regulator should shut down due to system fault, a message will immediately
begin to scroll across the display to explain the reason for the shut down. See
Section 3.2.4 for further information.
L-829 only
If a lamp out monitor or brightness step monitor fault is detected, the display will
continue to read current, but a “*” will appear to the right of the current reading. See
Section 3.2.4 for further information.

Rev. W
3.2.3
Monitor Calibration (L-829 only)
Calibrating the monitor does not require any tools. All that you need to know is the
number of lamps in the circuit and at what number of lamp burn outs you want the
warning and alarm functions to activate. If you wish, you may elect to calibrate the
monitor in percentage rather than lamp count. This is recommended when there are
different lamp wattages, very few lamps, many lighted signs or more than 200 lamps
on the circuit. Complete instructions are provided below. A flow chart is also
provided in Figure 3-3.
TO CALIBRATE THE MONITOR:
BEFORE CALIBRATING THE MONITOR, BE SURE ALL THE LAMPS ARE OPERATING
PROPERLY. IF SOME ARE BURNED OUT, THEY WILL BE IGNORED BY THE
MONITOR!!.
(Remember - Press “A” to ABORT if you make a mistake.)
Press “CC(Enter)” -
This enters the calibrate mode. The CCR will turn off and
the prompt LMPS = XXX where XXX equals the number of
lamps previously entered (100 if in percent mode) will
appear on the display.
If you wish to use the lamp mode:
Press the keys for the number of lamps in the load, followed by “E” for Enter.
All future prompts will refer to number of lamps.
If you wish to use the percent mode:
Press “C” for “Change” - the display will now prompt “PERCENT?”.
If you change your mind and want to go back to lamp mode, press “C” again.
If you are sure you want percent mode press “(Enter)”. The number of lamps
is not important in percent mode. All future prompts will refer to percentage
of the total load.
The next prompt in either monitor mode is “WARN = XX”. Where “XX” = the lamps or
percent previously entered. Press the keys for the number or percentage of lamps at
which the warning signal is to be activated, followed by “E” for Enter. If you are not
using the warning signal, enter any number (a number must be entered).
At the prompt NORM = XX, WHERE “XX” equals the lamps or percent previously
entered, press the keys for the number or percentage of lamps at which the Primary
Alarm signal should activate, followed by “E” for Enter. In the FAA Advisory Circular
this is called the Normal operation mode.
16
9540
Rev. W
The last data entry is at the DEGR = “XX” where XX equals the lamps or percent
previously entered prompt. Press the keys for the number or percentage of lamps at
which the Secondary Alarm signal should activate followed by “E” for Enter. In the
FAA Advisory Circular this is called the degraded operation mode. This entry must be
higher than the Primary Alarm entry or an error message will appear.
At this point the monitor will ask permission to perform automatic calibration with
the prompt “AUTOCAL?”. Check to be sure the load circuit is connected and no
personnel are working on it. When you are sure of these things, press “E” (for Enter).
The monitor now will assume control of the regulator, turning it on to the highest
brightness step. The monitor will automatically adjust for the load circuit and then
proceed to the lower steps. For a 5 step CCR, it will do B3-B5, A 1 or 3 step will be
monitored at every step. This normally takes about 5 minutes. You can check on the
progress of this calibration by watching the starts (“*”) on the display. Each time a
step change take place, one star will go out.
When the calibration procedure is finished, the display will read “COMPLETE” for
about one second and then normal display operation will resume. If the regulator
was in remote control mode before calibration, it must be reset to remote by pressing
“BB(Enter)”.
3.2.4
Monitor Operation (L-829 only)
After calibration the monitor will continuously operate in both local and remote
control modes. The lamp-out monitor always begins in the Primary Alarm (Normal)
mode. To switch to the Secondary Alarm (Degraded) mode, press “CD(Enter)” on the
keypad. To return to Primary Alarm mode, press “CB(Enter)” on the keypad.
If a regulator shutdown occurs you can find out what happened by reading the
display:
“HIGH LOAD CURRENT” -
Over current protection trip.
“OPEN LOAD CURRENT” -
Open Load protection trip.
“LOW INPUT LINE”
Low line voltage trip.

Other monitor alarms, which do not result from complete regulator shutdown, are
indicated by one star (“*”) to the right of the load current reading on the display. To
find out exactly what is happening, press “CF(Enter)” on the keypad. One of the
following messages will scroll across the display.

CORRECTIVE MAINTENANCE
Corrective maintenance is required when the regulator does not work properly. This
usually requires the replacement of parts or subassemblies. The use of easily
removable subassemblies make repair a simple task. The removal and replacement
method should be obvious to qualified maintenance personnel.
WARNING
VOLTAGES ABOVE 1000 VOLTS ARE PRESENT WHEN THE REGULATOR IS
OPERATING.
DO NOT REPAIR OR SERVICE WITHOUT FIRST REMOVING
POWER FROM THE REGULATOR.
THE USE OF LOCK-OUT DEVICES IS
RECOMMENDED.
The control assembly contains parts which can be replaced in the field by a service
person. If properly trained personnel are not available, replace the entire control
assembly. Improper removal and handling can cause damage to the equipment.
Particular areas of concern are:
4.3
(A)
Remove power from the regulator before disconnecting the connector plug
from the control compartment.
(B)
Depress the serrated release on the connector to remove it from the control
compartment. DO NOT try to remove by pulling on the wire harness. See
Figure 4-1 for operation of the connector.
(C)
CAUTION:

SENSITIVE. Do not remove or handle them without a static control wrist
strap.
PROBLEM SOLVING GUIDE
This guide will assist qualified airport maintenance personnel in locating and
correcting equipment failures.
Problems associated with option functions are
addressed in the specific option Supplement. If further assistance is required,
contact the Customer Service Department at Crouse-Hinds Airport Lighting Products,
Windsor, Connecticut.
4.3.1
FAULT ISOLATION
The first step in fault isolation is the preliminary evaluation. Start by checking for
disconnected wires, switches in the wrong position, blown or missing fuses, etc.
Determine if other equipment on the same circuit is operating properly. Be sure that
the equipment is being used properly by checking the operation instructions. Finally,
if the digital display is working, use the displayed message to localize the problem.
23

Rev. W
If these checks do not pinpoint the problem, try operating the regulator with a short
across the load terminals. OPERATING INTO A SHORT WILL NOT HARM THE
REGULATOR. This is the best way to find out if the problem is with the regulator or
the load circuit. Once these checks have been made, refer to the checklist for further
instructions.
