INTRODUCTION
1.1
Scope and Purpose of document
This handbook is for use solely with the equipment identified by the AFL Part Number shown on the
front cover. It is not to be used with any other equipment unless specifically authorised by Aerial
Facilities Limited.
The purpose of this handbook is to provide the user/maintainer with sufficient information to service
and repair the equipment to the level agreed. Maintenance and adjustments to any deeper level must
be performed by AFL, normally at the company’s repair facility in Chesham, England.
This handbook has been prepared in accordance with BS 4884, and AFL’s Quality procedures, which
maintain the company’s registration to BS EN ISO 9001:2000 and to the R&TTE Directive of the
European Parliament. Copies of the relevant certificates and the company Quality Manual can be
supplied on application to the Quality Manager.
This document fulfils the relevant requirements of Article 6 of the R&TTE Directive.
1.2
Limitation of Liability Notice
This manual is written for the use of technically competent operators/service persons. No liability is
accepted by AFL for use or misuse of this manual, the information contained herein, or the
consequences of any actions resulting from the use of the said information, including, but not limited
to, descriptive, procedural, typographical, arithmetical, or listing errors.
Furthermore, AFL does not warrant the absolute accuracy of the information contained within this
manual, or its completeness, fitness for purpose, or scope.
AFL has a policy of continuous product development and enhancement, and as such, reserves the
right to amend, alter, update and generally change the contents, appearance and pertinence of this
document without notice.
All AFL products carry a twelve month warranty from date of shipment. The warranty is expressly on a
return to base repair or exchange basis and the warranty cover does not extend to on-site repair or
complete unit exchange.

SAFETY CONSIDERATIONS
2.1
Earthing of Equipment
Equipment supplied from the mains must be connected to grounded outlets and earthed
in conformity with appropriate local, national and international electricity supply and
safety regulations.
2.2
Electric Shock Hazard
The risk of electrical shocks due to faulty mains driven power supplies whilst
potentially ever present in any electrical equipment, would be minimised by adherence
to good installation practice and thorough testing at the following stages:
a)
Original assembly.
b)
Commissioning.
c)
Regular intervals, thereafter.
All test equipment must be in good working order prior to its use. High current power supplies can be
dangerous because of the possibility of substantial arcing. Always switch off during disconnection and
reconnection.
2.3
RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs
connected to AFL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a
‘spare’ output has been left un-terminated. Either of these conditions would impair the
system’s efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would severely
mitigate against the efficient radiation of RF power. Radio frequency burns could also be a hazard, if
any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory) regarding
exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of
producing RF field strengths, which may exceed guideline safe values especially if used with
antennas having appreciable gain. In this regard the use of directional antennas with backscreens
and a strict site rule that personnel must remain behind the screen while the RF power is on, is
strongly recommended.
Where the equipment is used near power lines or in association with temporary masts not having
lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.
2.4
Lifting and other Health and Safety Recommendations
Certain items of AFL equipment are heavy and care should be taken when lifting them
by hand. Ensure that a suitable number of personnel, appropriate lifting apparatus and
appropriate personal protective equipment is used especially when installing Cell
Enhancers above ground e.g. on a mast or pole.

2.5
Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes
used in devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide
dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if
ingested or by contact.
Products that contain beryllium are load terminations (dummy loads) and some power amplifiers.
These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown
above). They are marked as hazardous in line with international regulations, but pose no threat under
normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic
failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created
will be contained within the equipment module as long as the module remains sealed. For this reason,
any module carrying the yellow and black danger sign should not be opened. If the equipment is
suspected of failure, or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for
disposal.
To return such equipment, please contact the Quality Department, who will give you a Returned
Materials Authorisation (RMA) number. Please quote this number on the packing documents, and on
all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation barrier.
This material should never be heated to the point where smoke or fumes are evolved. Any person
feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes should seek medical
attention.
2.6
Laser safety
General good working practices adapted from
EN60825-2: 2004/ EC 60825-2:2004
Do not stare with unprotected eyes or with any unapproved optical device at the fibre ends or
connector faces or point them at other people, Use only approved filtered or attenuating viewing aids.
Any single or multiple fibre end or ends found not to be terminated (for example, matched, spliced)
shall be individually or collectively covered when not being worked on. They shall not be readily
visible and sharp ends shall not be exposed.
When using test cords, the optical power source shall be the last connected and the first
disconnected; use only approved methods for cleaning and preparing optical fibres and optical
connectors.
Always keep optical connectors covered to avoid physical damage and do not allow any dirt/foreign
material ingress on the optical connector bulkheads.
The optical fibre jumper cable maximum bend radius is 3cm; any smaller radii may result in optical
cable breakage or excessive transmission losses.
Caution: The FO units are NOT weather proof.

Description
This shelf is the interface between the system’s 800MHz bi-directional tunnel amplifiers and the off-air
antenna.
In the downlink direction, the incoming antenna RF is directed through a bandpass filter to a pair of
20dB gain low noise amplifiers that have a switchable 0-30dB attenuator between them. The resultant
single path is then divided several times and fed out of the shelf to the channel selective modules (x
24). When the outputs from the channel modules return, they are combined and exit to the two power
amplifier shelves that serve the East and West tunnel leaky feeders.
The uplink path originates from the tunnel antennas, and is band-selectively amplified and fed to a
pair of 10W power amplifiers. This final amplification stage in the uplink path has an automatic gain
control detector and attenuator to help negate the overloading effect of someone operating a mobile
close to the LCX tunnel antennas.
Note that this shelf has its own, dedicated mains driven, 12-15V DC PSU unit.

VHF/ UHF Programming Procedure
The operating frequency for each channel in the Cell Enhancer is programmed by 16 DIL (Dual In
Line) switches. The programming switches are mounted in the Channel Control Modules which are
located beside the channel modules in the module racking. The Channel Selectivity Modules are
connected to the Channel Control Module via 25 way ribbon cables.
Switch 16 is at the far left of the line of switches leading down to Switch 1 at the far right of the line.
Adjacent to the DIL switches for each channel is a toggle switch to turn on and off individual channels
as required. A green LED indicates the DC ON status of each channel.
A red LED shows the alarm condition for each channel. An illuminated alarm LED indicates that the
synthesiser has not achieved phase lock and that the module is disabled. There is a problem which
requires investigation, often a frequency programmed outside the operating frequency range.
The following information is necessary before attempting the programming procedure.
1)
2)
3)
operating frequency
synthesiser channel spacing (step size)
synthesiser offset (IF)
Check that the required frequency falls within the operational frequency limits of the Cell Enhancer.
For each channel required, subtract the synthesiser offset from the required operating frequency and
record the resulting local oscillator frequency.
Divide each local oscillator frequency by the channel spacing and check that the result is an integer
(i.e.: no remainder).
If the synthesiser division ratio is not an integer value, check the required operational frequency and
repeat the calculation checking for mistakes.
Convert the required local oscillator frequency to synthesiser programming switch state patterns
according to the following table.

Frequency required:
465.5MHz
Channel spacing:
12.5kHz
Synthesiser offset:
21.4MHz
The Local Oscillator frequency is therefore: 465.4 – 21.4 = 444.0 MHz
Dividing the LO frequency
by the channel spacing of:
0.0125MHz:
444.0
0.0125
= 35520
This is an integer value, therefore it is OK to proceed.

900MHz Programming Procedure
Check that the required downlink and uplink frequencies fall within the operational band limits of the
Cell Enhancer.
For each Downlink and Uplink channel frequency, subtract the appropriate synthesiser offset
frequency from the required operational frequency and record the resulting local oscillator
frequencies.
Divide each Downlink and Uplink local oscillator frequency by the synthesiser channel spacing and
check that the result is an integer (i.e. no remainder).
If the synthesiser division ratio is not an integer value, check the required operational frequency and
repeat the calculation checking for mistakes.
Convert the required local oscillator frequency to synthesiser programming switch state patterns
according to the following table.
NOTE: Ensure that the correct column is used from the table below according to the synthesiser
channel spacing of the particular channel modules fitted to the Cell Enhancer.

Description
The 40Watt master site power amplifier shelf concerns itself with powering the 800MHz channel
information to the LCX tunnel antennas. The output from the channel module shelves is split into two
and input to each of the two PA shelves. Each PA powers either the East or West tunnel leaky feeder
antennas and a proportion of the LCX signal provides a feed to the 800MHz in-line amplifiers that
power the fire exit stairs antennas. All amplifiers in the shelf have alarms and they terminate at the
rear panel mounted 9-way ‘D’ connector, pins 1 & 2.
Since the Mission Valley system was first commissioned, the upgrade was designed and built using a
high power shelf (50-078005) instead of the 40Watt shelf described here. Therefore, this section is
shown for information only.

Page 31 of 85
3.10.1 Description
The VHF simplex shelves are two-path, single frequency cell enhancers that cut the DC power (and
thereby mute the amplifiers) to the opposing path whenever a signal is detected. This is achieved by
using highly accurate crystal filters to set the exact channel frequency and speciality channel selective
modules that react to detectors placed in each path. There are also switched attenuators before and
after the channel modules in order to accurately set the RF threshold levels for correct simplex
operation (this will already have been achieved at the time of final system test and should not need
adjustment). Isolators at the outputs of each path protect the power stages from potentially damaging
stray interference from other channels.
Each amplifier in the simplex CE shelves has an alarm as do the channel modules and the summary
alarms terminate at the rear panel mounted 9-way ‘D’ connector, pins 1 & 2.

3.12.1 Description
The duplex shelves are part of the VHF amplification system and like the simplex shelves, have
crystal filters instead of bandpass filters to set frequencies and bandwidths. There are two downlink
channels and two uplink channels, the downlink paths having isolators fitted to each of the 5Watt
output stages to prevent interfering reflections from the other channel.
The uplink channel modules have a dedicated noise muting circuit fitted externally to the channel
module which operates when the downlink path is active.
All amplifiers have built-in alarms which are configured as a summary, volt-free relay contact pair
terminating at pins 1 & 2 on the rear panel mounted ‘D’ type alarm connector.

VHF Air Interface Shelf (50-078012)
3.13.1 Description
The VHF system is provided with three Yagi off-air antennas, two downlink, receiving downlink signals
from two different directions, and one uplink, facing the nearest BTS. Bandpass filters exclude
extraneous noise on the frequency bands to be processed and once filtered, the downlink signal is
amplified (10dB gain) and separately split to the simplex and duplex shelves’ inputs. The uplink
outputs from these six VHF shelves are combined, filtered and sent directly to the uplink off-air Yagi
antenna. The downlink low-noise-amplifier has an alarm, configured as a summary, volt-free relay
contact pair terminating at pins 1 & 2 on the ‘D’ type alarm connector.

3.14.1 Description
The purpose of the VHF combiner is to take the downlink products of all the VHF shelves and
combine them together so that they may, in turn, be combined with the 800MHz signals from the
cellular amplifiers to feed the tunnel antennas. The reverse is true of the uplink path where the VHF
signals from each of the tunnel antennæ are coupled from the 800MHz signals, filtered, amplified,
combined and then split equally for the inputs of the VHF uplink amplifiers.
The uplink low-noise-amplifier used in the shelf, has an alarm pair, configured as a summary, volt-free
relay contact pair terminating at pins 1 & 2 on the ‘D’ type alarm connector.

VHF/800MHz Tx Multi-coupler (50-078015)
3.16.1 Description
The multi-coupler shelf interfaces the VHF/UHF and 800MHz power output signals together to drive
the downlink Tx antennas and to receive the low-level signals from the uplink antennas prior to their
amplification and re-broadcast bask to the BTS.
This purely passive shelf is a mix of hybrid, cross-band and directional couplers which pass the
downlink signals with as little insertion loss as possible and the uplink signals with as good
isolation/rejection as possible. This shelf has no power source and no alarms.

4.1.1
Description
The wall mounted tunnel BDA is a band-selective unit which draws its RF from the tunnel leaky feeder
coaxial cable, feeding separate down and uplink ports and operating in the 800MHz frequency region
with a cross-band coupled bypass to allow VHF signals to be passed through the amplifier with just a
small loss. (The loss at 800MHz is considerable compared with the VHF signals, so a small amount of
gain at 800MHz is required to overcome these losses, whereas the VHF signals need no boosting).
The primary application for the BDA is to boost the 800MHz and VHF signals in areas of the West
Tunnel and Fire Exits where coverage would otherwise be inadequate. Notice that each path has
automatic gain control as the amplifier receives its input from the leaky feeder antennas for both up
and downlink. This means that the signal could have large differences in level at any time which is
why the AGC is needed on both paths.
The amplifier needs 12V DC for its supply, and this enters from the BBU unit through a rugged
connector mounted on the R.H.S (viewed from front) of the case. For further notes on the use of the
battery backup system, see the dedicated BBU handbook at the end of this document (appendix B).

MASTER SITE UPGRADE
5.1
Master Site Upgrade Rack Assembly (50-078021)
5.1.1
Master Site Upgrade Rack Description
This upgrade to the Mission Valley radio repeater system is concerned only with the 800MHz band of
frequencies, which, in the original specification could carry up to 24 channels of cell data
simultaneously. The added hardware for this upgrade will increase the number of available channels
from 24 to 43 but the number of 19” racks remains at three (the original 40W amplifier shelves will not
now be needed and three new channel module shelves will be added).
The cellular amplifier is in addition to the 24 channels already in existence, the increase (19 channels,
6 x 8ch. sub-racks) is designed to alleviate radio congestion to the local BTS and to extend the
number of possible simultaneous uses. Because of the increased channel density, a pair of 80100Watt power amplifier shelves (50-146703), instead of the original 40Watt pair, are the main source
of downlink RF power in the system to maintain the effective power/channel. Only the downlink path is
channelised, the uplink path is band-selective and its traffic is limited only by the total carrier power
available.
All shelves have active device alarms and these are configured as a volt-free, relay contact pair
summary per shelf, terminating in the 9-way ‘D’ connector on the rear panel, pins 1 & 2.
The VHF system needs no upgrade at this time, so the VHF hardware remains the same.

Description
These new high power (80Watts) amplifier shelves have been introduced in place of the 40W
amplifiers originally supplied. The higher power amplifiers are needed to maintain sufficient power per
channel for the 800MHz cellular repeater as there are now 19 extra channels. This shelf has two
amplifiers, a low noise amplifier and a low power (2W) amplifier which acts as a driver for the high
power shelf (50-146703). A 0-15dB switched attenuator at each of the two inputs allows accurate
balancing of the signal through the high power stages. As with all other shelves, alarms exist for all
the amplifiers and they terminate on the rear panel ‘D’ connector as a summary, volt-free relay
contact pair, pins 1 & 2.

INSTALLATION
When this equipment is initially commissioned, please use the equipment set-up record sheet in
Appendix B. This will help both the installation personnel and AFL should these figures be needed for
future reference or diagnosis.
6.1
General Remarks
The equipment racks that these master site shelves will be fitted into must be located on a flat, level
surface that is made from a material suitable for bearing the weight of the rack assembly. If the
installer is in any doubt about the suitability of a site it is recommended that he consult with an
appropriately qualified Structural Engineer.
It is important in determining the location of the rack within the room that space is allowed for access
to the front and rear of the equipment. To enable maintenance to be carried out, the doors must be
able to fully open.
The location must be served with a duct to allow the entry of cables into the unit.
The mains power supply is connected to the terminal strip located on the bulkhead at the rear of the
equipment at floor level. It is recommended that the connection is made by a qualified electrician, who
must satisfy himself that the supply will be the correct voltage and of sufficient capacity.
All electrical and RF connection should be completed and checked prior to power being applied for
the first time.
6.2
RF Connections
Care must be taken to ensure that the correct connections are made with particular attention made to
the base station TX/RX ports.
In the event that the base transmitter is connected to the RX output of the rack, damage to the
equipment will be done if the base station transmitter is then keyed.
Ensure that connections are kept clean and are fully tightened.
6.3
Commissioning
Once all connections are made the equipment is ready for commissioning.
Using the system diagrams and the end-to-end test specification, the equipment should be tested to
ensure correct operation.
On initial power up the system alarm indicators on the front panels of the equipment should be
checked. A red LED illuminated indicates a fault in that particular tray that must be investigated before
proceeding with the commissioning. A green LED on each shelf illuminates, to indicate that the power
supply is connected to the shelf
In the event that any part of the system does not function correctly as expected, check all connections
to ensure that they are to the correct port, that the interconnecting cables are not faulty and that they
are tightened. The majority of commissioning difficulties arise from problems with the interconnecting
cables and connectors.

MAINTENANCE
7.1
Fault Finding
7.1.1
Quick Fault Checklist
All AFL equipment is individually tested to specification prior to despatch. Failure of this type of
equipment is not common. Experience has shown that a large number of fault conditions relating to
tunnel installations result from simple causes often occurring as result of transportation, unpacking
and installation. Below are listed some common problems which have resulted in poor performance or
an indicated non-functioning of the equipment.
Mains power not connected or not switched on.
External connectors not fitted or incorrectly fitted.
Internal connectors becoming loose due to transport vibration.
Wiring becoming detached as a result of heavy handling.
Input signals not present due to faults in the aerial and feeder system.
Base transmissions not present due to fault at the base station.
Modems fitted with incorrect software configuration.
Changes to channel frequencies and inhibiting channels.
Hand held radio equipment not set to repeater channels.
Hand held radio equipment not set to correct base station.
7.1.2
Fault Isolation
In the event that the performance of the system is suspect, a methodical and logical approach to the
problem will reveal the cause of the difficulty. The system consists of modules fitted in shelves within
an environmentally protected enclosure (rack).
Transmissions from the main base stations are passed though the system to the mobile radio
equipment; this could be a handheld radio or a transceiver in a vehicle. This path is referred to as the
downlink. The return signal path from the mobile radio equipment to the base station is referred to as
the uplink.
The first operation is to check the alarms of each of the active units and determine that the power
supplies to the equipment are connected and active.
This can be achieved remotely (via CEMS, the RS232 Coverage Enhancement Management System,
if fitted), or locally with the front panel LEDs. The green LED on the front panel should be illuminated,
while the red alarm indicator should be off. If an alarm is on, then that individual module must be
isolated and individually tested against the original test specification.
The individual amplifier or FO units within the shelf have a green LED showing through a hole in their
piggy-back alarm board, which is illuminated if the unit is working correctly. If a module is suspect,
check the DC power supply to the unit. If no other fault is apparent use a spectrum analyser to
measure the incoming signal level at the input and then after reconnecting the amplifier input,
measure the output level. Consult with the system diagram to determine the expected gain and
compare result.
In the event that there are no alarms on and all units appear to be functioning it will be necessary to
test the system in a systematic manner to confirm correct operation.

7.1.3
Downlink
Confirm that there is a signal at the expected frequency and strength from the base station. If this is
not present then the fault may lay outside the system. To confirm this, inject a downlink frequency
signal from a known source at the master site BTS input and check for output at the remote site
feeder output.
If a signal is not received at the output it will be necessary to follow the downlink path through the
system to find a point at which the signal is lost. The expected downlink output for the given input can
be found in the end-to-end test specification.
7.1.4
Uplink
Testing the uplink involves a similar procedure to the downlink except that the frequencies used are
those transmitted by the mobile equipment.
7.1.5
Checking service
Following the repair of any part of the system it is recommended that a full end-to-end test is carried
out in accordance with the test specification and that the coverage is checked by survey.
It is important to bear in mind that the system includes a radiating cable network and base stations
that may be faulty or may have been damaged.

7.1.6
Fault repair
Once a faulty component has been identified, a decision must be made on the appropriate course to
carry out a repair. A competent engineer can quickly remedy typical faults such as faulty connections
or cables. The exceptions to this are cable assemblies connecting bandpass filter assemblies that are
manufactured to critical lengths to maintain a 50-ohm system. Care should be taken when replacing
cables or connectors to ensure that items are of the correct specification. The repair of component
modules such as amplifiers and bandpass filters will not usually be possible in the field, as they
frequently require specialist knowledge and test equipment to ensure correct operation. It is
recommended that items of this type are replaced with a spare unit and the faulty unit returned to AFL
for repair.
7.1.7
Service Support

Care of Modules
7.3.1
General Comments
Many of the active modules contain semiconductor devices utilising MOS technology, which can
be damaged by electrostatic discharge. Correct handling of such modules is mandatory to ensure
their long-term reliability.
To prevent damage to a module, it must be withdrawn/inserted with care. The module may have
connectors on its underside, which might not be visible to the service operative.
7.3.2
Module Removal (LNAs, general procedure):
The following general instructions should be followed to remove a module:
Remove power to the unit
Remove all visible connectors (RF, DC & alarm)
Release module retaining screws.
Slowly but firmly, pull the module straight out of its position. Take care not to twist/turn the
module during withdrawal. (When the module is loose, care may be needed, as there may be
concealed connections underneath).
7.3.3
Module Replacement (general):
Carefully align the module into its location then slowly push the module directly straight into its
position, taking care not to twist/turn it during insertion.
Reconnect all connectors, RF, alarm, power etc.,(concealed connectors may have to be
connected first).
Replace retaining screws (if any).
Double-check all connections before applying power.
7.3.4
Power Amplifiers
1) Remove power to the unit. (Switch off @ mains/battery, or remove DC in connector)
2) Remove alarm wires from alarm screw terminal block or disconnect multi-way alarm
connector.
3) Carefully disconnect the RF input and output coaxial connectors (usually SMA)
If alarm board removal is not required, go to step 5.
4) There is (usually) a plate attached to the alarm board which fixes it to the amplifier, remove its
retaining screws and the alarm board can be withdrawn from the amplifier in its entirety. On
certain types of amplifier the alarm board is not mounted on a dedicated mounting plate; in this
case it will have to firstly be removed by unscrewing it from the mounting pillars, in most
cases, the pillars will not have not have to be removed before lifting the amplifier.
5) If the amplifier to be removed has a heatsink attached, there may be several different ways it
can have been assembled. The most commonly used method, is screws through the front of
the heatsink to threaded screw holes (or nuts and bolts), into the amplifier within the main
case. If the heatsink is mounted on the rear of the main case (e.g., against a wall in the case
of wall mounted enclosures), then the fixing method for the heatsink will be from within the
case, (otherwise the enclosure would have to be removed from the wall in order to remove the
heatsink).
When the heatsink has been removed, the amplifier may be unscrewed from the main casing by its
four corner fixings and gently withdrawn.
Fitting a new power amplifier module will be the exact reverse of the above.
Note: Do not forget to apply fresh heatsink compound to the heatsink/main case joint and
also between the amplifier and the main case.

7.3.5
Low Power Amplifier Replacement
Disconnect the mains power supply and disconnect the 24V dc supply connector for the LPA.
Disconnect the RF input and output cables from the LPA.
Disconnect the alarm connector.
Remove the alarm monitoring wires from (D type connector) pins 9 and 10.
Remove the LPA module by removing the four retaining screws, replace with a new LPA
module and secure it with the screws.
Connect the RF cables to the LPA input and output connectors. Reconnect the wires to the
alarm board connector pins 9 and 10.
Reconnect the DC supply connector and turn the mains switch on.
Note:
Tighten SMA connectors using only a dedicated SMA torque spanner. If SMA
connectors are over-tightened, irreparable damage will occur. . Do not use adjustable
pliers to loosen/tighten SMA connectors.
Also take care not to drop or knock the module as this can damage (or misalign in the case of
tuned passive modules) sensitive internal components. Always store the modules in an
environmentally friendly location
7.3.6
Module Transportation:
To maintain the operation, performance and reliability of any module it must be stored and
transported correctly. Any module not installed in a whole system must be kept in an anti-static bag or
container. These bags or containers are normally identified by being pink or black, and are often
marked with an ESD label. Any module sent back to AFL for investigation/repair must be so
protected. Please contact AFL’s quality department before returning a module.

APPENDIX C - BATTERY BACKUP
C.1
GENERAL DESCRIPTION
The 80-209302 Battery Backup Unit is designed to complement AFL’s extensive range of Cell
Enhancers and provide for continued operation during mains power failure.
The Battery Backup Unit is mounted in a single environmentally-protected case. NOTE:
Although battery back-up units are fitted in an IP65 case, they are open to the local
environment via coarsely filtered grill apertures which are necessary to allow the escape of
gasses from the batteries when they are being charged or discharged. Handles are provided
for carrying the unit and the door is fitted with locks. All the power and alarm connections are
via rugged IP68 sealed connectors.
The Battery Backup Unit contains a switch-mode power supply module (SMPSU), the batteries,
a battery charger and the associated control circuitry. In particular a low-voltage cut-off is fitted
to shut the system down after extended operation to prevent deep discharge of the batteries.
The Battery Backup Unit is fitted as standard with two alarms, a combined power supply and
charger alarm and an intruder alarm. The intruder alarm operates when the enclosure door is
opened. Both alarm circuits are volt-free contacts which are normally closed and become open
circuit in a fault condition. The Battery Backup Unit can be fitted with a more comprehensive
alarm and monitoring alarm system if required. In these cases the Battery Backup Unit can also
be fitted with alarms for AC failure, temperature, etc. and be interfaced for use with the Cell
Enhancer remote alarm reporting system.
When the Battery Backup Unit is used as the default power source for the Cell Enhancer, the
Cell Enhancer only requires a 12V DC supply input. This has the effect of removing the power
supply from the Cell Enhancer case, therefore saving on cost, weight and most importantly
reducing heat generation within the Cell Enhancer case.
The Battery Backup Unit is designed to provide typically four hours autonomy in the event of
mains supply failure. However, this will vary depending on the load presented by the Cell
Enhancer and the size of the batteries fitted.
The circuit diagram and schematic contained in this handbook are based on the standard
model. All Battery Backup Units are capable of being customised to individual customers
requirements for battery capacity, alarms etc. and the drawings may differ from those included
in this manual.

APPENDIX C Battery Backup
Handbook No. 50-078021HBKM
Page 78 of 85
C.3.3 Technical Description
AFL Cell Enhancer/repeater equipment often requires backup against failure of the mains AC supply.
Since the equipment runs on a 12V DC supply the most efficient method of providing backup is by a
bank of dry lead acid batteries of adequate capacity.
The Battery Backup Power Supply Unit incorporates a 400 Watt DC power supply and a
Charger/Regulator with a bank of two 12V 40AH batteries connected in parallel. The 400 Watt
SMPSU power supply will provide 12V DC to power the repeater under normal running conditions
from the mains supply. The batteries will provide 12V DC if the mains supply fails.
To reach maximum capacity the batteries need a charging voltage of 13.5V and this is provided by a
commercially available TRACO type TIS300-124 power supply with an output current capability of
10A maximum. The disadvantage with lead acid batteries is the high terminal voltage during charging.
AFL repeaters employ a diode combiner to sum the 12V DC output of the SMPSU DC power supply
and the battery bank DC output. The diode combiner is used to achieve "no break" changeover on
mains failure, however, if during charging the battery output has a greater voltage than the SMPSU
DC power supply the repeater will draw current from the batteries and not the SMPSU. A further
disadvantage is that the power dissipation in the repeater amplifiers is 30% greater with a 13.5V
supply and some power amplifier devices are rated to 14V maximum collector voltage leaving little
margin for safety.
To overcome these problems the Battery Backup Power Supply must regulate the battery voltage to
be slightly below that of the SMPSU. At the same time when the AC supply is off and the equipment is
running from batteries the voltage drop across the regulator must be a minimum to achieve maximum
backup time as the batteries discharge.
A further requirement is to prevent the effect known as "deep discharge" which shortens battery life.
This means the load must be disconnected from the batteries when they become discharged to a
terminal voltage of approximately 10.5V.
The charger power supply charges the 2 series connected batteries through blocking diodes. The
diodes prevent unwanted current flows between circuit elements. The battery charger DC output is
connected through the Battery Output ON/OFF switch to the Charger Control Board via a diode where
it powers the low voltage disconnect comparator. The comparator senses the battery voltage via a
potential divider and compares it to a fixed 5V reference. Adjustment of the potentiometer VR1 sets
the minimum battery voltage at which the low voltage disconnect relay remains energised and the
output to an 18V regulator is enabled.
In the absence of an AC input the supply to the comparator is maintained from the batteries via a
second diode through the contacts of the low voltage disconnect relay. When the comparator
releases the low voltage disconnect relay the comparator supply is interrupted. The low voltage
disconnect relay will then remain de-energised (Battery Output Off) until either the AC supply returns
or the Reset pushbutton is pressed. On actuation of the Reset pushbutton the output will be restored
provided the battery voltage exceeds the comparator threshold set by the potentiometer VR1.
Output from the low voltage disconnect relay is routed to the 9V regulator which provides a stabilised
9 Volt output determined by two divider resistors. This supply feeds a voltage doubler circuit
configured from a square wave multi-vibrator and two chopper field effect transistors. Two diodes
form the voltage doubling rectifier so that in normal operation approximately 33 Volts is available
across doubler circuit capacitors.
The 16 Volt supply is routed via the control element transistor to the gate of a Power MOSFET which
is the series pass element for regulating the 13.5V battery voltage to 12.5 Volts at the final output.
The FET is chosen for its ability to pass high currents (>30A) with a very low voltage drop (100mV).
To achieve this performance requires that the gate is at least 6V more positive than the drain &
source terminals. This is the reason for the Voltage doubler supply for driving the gate.
The output voltage is sensed by a second potential divider and compared with the reference voltage
from a zener diode to drive the control element transistor for the gate voltage of the pass element.
Adjustment of the second potentiometer VR2 sets the output voltage to the required value.

C.6. INSTALLATION
C.6.1 Battery Backup Unit Installation
The procedure for installing and commissioning an AFL Cell Enhancer Battery Backup Unit is
generally as follows:
Fix the Battery Backup Unit in the chosen position.
Connect a suitable mains power supply to the Battery Backup Unit.
Connect the DC cable from the Battery Backup Unit to the Cell Enhancer.
Switch the Battery Backup Unit on by switching on the two circuit breakers and the
battery output switch on the internal indicator panel.
Test the Cell Enhancer to ensure correct operation from the Battery Backup Unit.
C.6.2 Power Supply Input Voltage Selection
The SMPSU module used within the AFL Cell Enhancer Battery Backup Unit is capable of
operation at any voltage between 90 Vac and 264 Vac. The battery charger power supply (Traco)
must be switched to either 115 or 230V nominal AC supplies. The supply changeover switch is
located on the top surface of the battery charger supply near to the front of the battery backup
case. This slide switch is recessed within the supply and can be operated by a small screwdriver.
C.7. MAINTENANCE
C.7.1 General Comments
The AFL Cell Enhancer Battery Backup Unit requires no routine maintenance. If a failure is
suspected it is possible with the aid of the block schematics (see section 3) to locate any
defective unit.
It should be borne in mind that a failure indicated by the alarm system could actually be a failure
in the alarm system! It is always worth checking that there really is a genuine problem by AC and
DC voltage measurements before starting to dismantle parts of the system. Lead-acid batteries
should be inspected every year for general condition the same way an auto battery would be
regarded.
