1. SAFETY CONSIDERATIONS 1.1 Electric Shock Hazard Electrical shocks due to faulty mains driven power supplies. Whilst ever potentially present in any electrical equipment, such a condition would be minimised by quality installation practice and thorough testing at: a) Original assembly. b) Commissioning. c) Regular intervals, thereafter. All test equipment to be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing.
1.3 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).
2. OVERVIEW/SYSTEM DESCRIPTION The AFL Fibre feed Amplifiers for the Pasadena Blue line project are 2 way on-band RF amplifiers. Their application is as an interface between the fibre optical link from the off air amplifiers and the tunnel antenna/leaky feeder system. There are two units one designated ‘UNIT 1’ for the frequencies in the 470-473MHz range , the other ‘UNIT 2’ for the frequencies in the 483-486MHz range. Each unit is housed in an environmentally protected IP65 steel wall-mount case.

5.1.4 3 Stage Amplifier Alarm Boards (12-002201) 5.1.4.1 Description Amplifier Alarm Boards are fitted to monitor the bias conditions of AFL Class A amplifiers which remain constant in normal operation. Any departure from normal bias conditions is a result of device failure, excess temperature, over-driving or oscillation (excessive power). In normal operation, the Class A bias circuit of the amplifier develops a constant voltage of 1.20V across the collector current setting resistor.

5.1.6 DC/DC Converter, 24V in, 12V 8A out (13-003011) 5.1.6.1 Description The DC/DC converter fitted is an AFL assembled, high power PCB unit with an 8 amp @ 12V output capability. The circuit is basically an O.E.M semiconductor regulator (one side of which has a heatsink mounting plate, that is usually bolted to the casing of a Cell Enhancer) and smoothing components built onto a printed circuit board with screw block terminations. Note: no circuit diagram of the O.E.M. regulator is available.
5.1.7 Wide Dynamic Range AGC (17-001101, Det. & 17-001201, Atten.) 5.1.7.1 Description The equipment is fitted with a wide dynamic range Automatic Gain Control (AGC) system. This is generally fitted in the Uplink path (not usually needed in the downlink path, as the signal here is at an almost constant level), to avoid overloading the amplifiers (with the associated performance degradation) should a mobile be operated very close to the unit.
For small signals, below AGC onset, the output control line will be close to 12V and the AGC attenuator will have minimum attenuation. As the signal level increases the control line voltage will fall, increasing the attenuator value and keeping the system output level at a constant value. The AGC onset level is adjusted by the choice of sampler resistor R1 and by the setting of potentiometer VR1. The attenuator comprises a 50? P.I.N diode, voltage-variable attenuator with a range of 3 to 30dB.

6. INSTALLATION 6.1 Initial Installation Record When this equipment is initially commissioned, please use the equipment set-up record sheet in Appendix A. This will help both the installation personnel and AFL should these figures be needed for future reference or diagnosis. 6.2 General The size and weight of the wall units mean that they represent a significant health hazard unless they are mechanically installed in the correct manner.
6.5 RF Connections All RF connections are made to the cable termination, located on the right-hand side of the wall enclosure. 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 may be done if the base station transmitter is then keyed. If the environment where the equipment is installed is deemed to be ‘wet’ i.e.
7. MAINTENANCE 7.1 General Procedures 7.1.1 Fault Finding 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 within a wall mounted, environmentally protected enclosure. Transmissions from the main base stations are passed though the system to the mobile radio equipment; this could be a handheld walkie-talkie, mobile telephone or a transceiver in a vehicle.
7.1.2 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.
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 Service Support Advice and assistance with maintaining and servicing this system are available by contacting Aerial Facilities Ltd. 7.
7.3 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.
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.
