TECHNICAL DESCRIPTION
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
opto-couplers for transient protection.
5
9525
Rev. P
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 threestep 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 re-energize 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 2 seconds, the control system performs the same
shutdown sequence as for overcurrent protection.

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 deenergized 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
immediately, thereby signaling a regulator fault.
2.1.7.4
the
monitor
relay
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 de-energized. 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.

Rev. P
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 deenergize.
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 3-4 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
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:

or
Press “B1 (Enter)”
To select B30 -
Press “B30 (Enter)”
or
Press “B2 (Enter)”
To select B100 -
Press “B100 (Enter)”
or
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.

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 3-5.
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:

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
9525
Rev. P
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 B2-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)”.
If the load is less than 50% of the regulator’s capacity, the
regulator will shut off and the display will read “Load Too Small.”
The regulator must be loaded to 50% or more of its capacity to use the
lamp-out monitor.
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
To return to

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:

(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: The circuit cards within the control assembly are
STATIC SENSITIVE. Do not remove or handle them without an
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.
25
9525
Rev. P
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.

DETAIL PROBLEM SOLVING GUIDE
On the next few pages are detail problem solving guides. These guides
make use of the digital display and the indicators on the control box
circuit cards to speed repair.
4.3.2.1
OPENING THE CONTROL BOX
TURN OFF MAIN POWER TO THE REGULATOR BEFORE STARTING:
To open the control box, swing it away from the cabinet and unplug the
connector. Then use a screw driver to remove the top cover screws.
Be careful to keep screws from falling into the box, as they could
short out components inside. Plug the connector back in. Default the
interlock switch by pulling the interlock switch actuator out. Turn
on main power to regulator to begin trouble-shooting. DANGER; BE
CAREFUL! THE CIRCUITS INSIDE THE CONTROL BOX ARE LIVE AND CONTAIN
DANGEROUS CURRENT LEVELS.
