3.2 BHPS Functions

This section describes the following functional blocks:

Circuit breakers

Temperature switches

Control board

Distribution board

Battery charger

Heating regulator

Heat exchange regulator.

3.2.1 Circuit Breakers

Circuit Breakers, located on the front panel, are provided for the followingpower supply lines:

AC (Alternating Current) (8 A)

DC voltage (20 A).

The toggle levers are mechanically connected so all supplies to the BTS areswitched simultaneously, irrespective of which supply is actually in use.

3.2.2 Temperature Switches

The following three temperature switches control the power source for the

various parts of the BTS under the command of the Control Board.

Temperature Switch 1 connects 230 VAC mains power to one of the

following:

Position A connects directly to the HEAT

Position B connects one or two AC/DC Power Supply submodules and

Temperature Switch 3.

3.2.3 Control Board

The Control Board continuously monitors the cabinet and battery temperatures,using external sensors. The temperature switches control the power supplied tothe appropriate components in the cabinet. Temperature control signals arealso sent to the temperature regulation functions.

If the internal temperature is below 0 C when the BHPS is switched on (andAC mains is available), the BTS is warmed before it is powered up. This isdone using the HEAT, with the CFU1 and inner fan of the HEXU circulating thewarm air (with switches 1 and 2 in position A ).

If the internal temperature is above 0 C the BTS is powered up (switches 1and 2 change to position B ) and low power warming is continued up to 20 C(with switch 3 set to ON ).

If the internal temperature exceeds 40 C, the HEXU cools the air and the CFU1forces the cooled air to the BTS components.

The following table shows the operational status of the BHPS under eachenvironmental condition.

3.2.4 Distribution Board

The Distribution Board switches and distributes DC power to various BTScomponents.

During normal operation, the Distribution Board supplies the temperatureregulating equipment and the Control Board with DC power from the subrack(s)(generated in the ADPSs).

Each ADPS monitors its incoming AC power supply and raises an alarm tothe Distribution Board if it fails. The Distribution Board then switches over,supplying the subrack(s), temperature regulation equipment and the ControlBoard with DC power from the BBU2. The BBU2 maintains power until it isexhausted or AC power is resumed.

Note that switch over occurs only if the internal ambient temperature isabove 0 C. However, once DC power is switched on, it is not removed if thetemperature subsequently falls below 0 C.

Separating diodes are included in the supply paths of the DC-poweredequipment. These allow DC to be supplied either by the battery, chargingcircuit, or via the subracks without causing a short.

3.2.5 Battery Charger

The Battery Charger ensures the BBU2 is kept at full charge. To preventoverheating, the charging current is regulated according to the BBU2s internaltemperature.

The Battery Charger recharges the BBU2, whenever mains power is availableand the BBU2 temperature is above 0 C. Note that Temperature Switch 2 mustbe in position B (refer to Temperature Switches (Section 3.2.2) ). The BatteryCharger also supplies DC voltage to the Control Board and CFU1 during the

warm-up phase (via Temperature Switch 2).When operating from the BBU2 supply, a Low Voltage Protection circuit raises alow voltage alarm when the battery voltage drops to +41 VDC. If the voltagedrops to +40 VDC, the BTS is disconnected.

Note that the BHPS still operates (with reduced functionality) without a BBU2 -all AC supply and environmental control functions are maintained (see O&M(Section 3.4) ).

3.2.6 Heating Regulator

The Heating Regulator employs a chopper-circuit to control the average ACpower delivered to the HEAT. The Heat is supervised by the Control Board.

3.2.7 Heat Exchanger Regulator

The Heat Exchanger Regulator controls power to the HEXU fans by varying theDC voltage. When the cabinets internal temperature rises above 40 C, theHEXU is operated to reduce the temperature. The internal HEXU fan is alsoused to circulate air during warm-up.

4.2 PM06 Functions

The PM06 is the primary power supply submodule. It provides DC power forthe BTS.

Up to six PM06 are installed in the two PMSRs, sharing the supply load. Power

supply redundancy is provided by the number of PM06s installed.The following sections describe the PM06 main functional blocks:

AC/DC Converter

Output capacitors.

4.2.1 AC/DC Converter

A single-stage AC/DC Converter is contained in each PM06. The outputvoltage is temperature stabilized. Maximum output power is 550 W.

The input and output are fully protected against undesirable conditions,

including continuous short circuit.

4.2.2 Output Capacitors

The Output Capacitors smooth the output of the AC/DC Converter. (Furthercapacitors in the PMSR backpanel provide additional smoothing).

4 PM06/PSI1

4.3 PSI1 Functions

The PSI1 provides the interface between the PM06s and the BTS hardware. Inaddition, the PSI1 includes monitor and alarm generation functions.

The PSI1 contains the following functional blocks:

Phase control

Signaling chain control

Discharge supervision and Deep Discharge Switch

Alarm Interface

Connections.

4.3.1 Phase Control

The Phase Control block allows the use of either single or three phase mains

supplies.

The input supply lines L1, L2 and L3 are monitored. If only a single phase isprovided, the inputs are connected together so all PM06 inputs are suppliedby the single phase. If all three phases are provided, the PM06 inputs areshared between the phases.

If the mains supply fails, an alarm is raised at the Alarm Interface.

4.3.2 Signaling Chain Control

The Signaling Chain Control block provides a closed chain alarm monitoringsystem for the PM06s.

Normally closed alarm switches in the PM06s are connected in a chain,monitored by the Signaling Chain Control block. If a fault occurs in any PM06,the chain is broken. The Signaling Chain Control block then raises an alarm atthe Alarm Interface.

The signaling chain must only include the PMSR slots where PM06 modulesare installed: a jumper behind the front panel on the PSI1 is set to define thenumber of PM06 modules installed.

4.3.3 Discharge Supervision and Deep Discharge Switch

The Discharge Supervision block monitors the BU60 voltage during batterydischarge (when the BTS is battery powered after a power failure).

If the battery voltage drops below 44 VDC, a deep discharge alarm is raised atthe Alarm Interface. If the voltage drops to 42 VDC, BTS power is disconnectedvia the Deep Discharge switch.

During normal operation with mains power available, the BU60 charges throughthe shunt resistor.

4.3.4 Alarm Interface

The Alarm Interface provides external screw connections for the alarms raisedby the other PSI1 blocks:

Mains power failure

Battery deep discharge

Battery discharging

Power module failure (one or more PM06 modules is faulty, or the

temperature sensor is faulty).

4.3.5 Connections

The PSI1 provides the connections between the mains supply, Power Supplyand Battery Charger, and BTS functional modules:

AC power in (single or three phase)

DC power out

BU60

PM06 input/output.

DC supply bars provide the permanent connection between the outputs ofthe PM06s and the BU60.

In the event of a fault causing excessive battery current, fuses in the BU60connection blow.

5.1 Introduction

The HEAT (Heating Unit) is used only in the MCO2 and MCO4. Its purpose isto maintain the temperature inside the cabinet at a suitable operating level. Airis circulated through the HEAT and the other BTS components by cooling fans.

5.2 HEAT Functions

The principle components of the HEAT are two heating spirals. These aremounted in an aluminium frame which is mounted in the cabinet rack.

If the temperature is below -3 C, upon first switching on the BTS, the HEATbegins a warm-up period of between 30 and 40 minutes. During the warm-upperiod the fans are operated at low power to improve air circulation throughthe BTS.

Under normal operating conditions, the HEAT is only operated when thetemperature is less than +2 C. It is switched off when the temperature exceeds+7 C.

A thermostat monitors the internal temperature of the HEAT and automaticallyswitches it off if the temperature is too high. This protects the BTS fromoverheating in the event of a regulation or circulation fan failure.

The HEAT contains the following functional components:

Heating Spirals

Thermostatic Switch.

Note: The HEAT must be used in conjunction with a BHPS which provides thenecessary power control functions.

5.2.1 Heating Spirals

The two Heating Spirals each have a nominal power of 400 W and provide atotal heating power of 800 W.

5.2.2 Thermostatic Switch

The Thermostatic Switch has the operational characteristics listed in thefollowing table.

6.1 Introduction

To prevent dirt, insects or moisture entering outdoor BTSs, external air isnot used for forced cooling. The HEXU (Heat Exchanger Unit) provides analternative cooling mechanism, where a seal is maintained between the internaland external air.

Note: The HEXU is used only in the MCO2 and MCO4.

6.2 HEXU Functions

The HEXU contains a heat sink and two fans to circulate internal and externalair. The heat sink is cooled by blowing external air over its outside face. Theinternal air is in turn cooled by blowing it over the cold inside face of the heatsink. The internal and external air flows are kept completely separate. Each fanraises an alarm if a failure occurs.

The cool air from the HEXU is circulated by the CFU1, which force coolsthe BTS.

7.1 Introduction

HEX1 (Heat Exchanger 1) is used only in the OBC3. Its purpose is to regulatethe internal temperature of the BTS.

To prevent dirt, insects or moisture entering the OBC3, external air is not used

for forced cooling. The HEX1 includes a heat exchanger cooling mechanism,maintaining a seal between the internal and external air.

A heater is included to ensure the BTS internal temperature is maintainedabove the freezing point.

Units The HEX1 comprises two units:

HEF1, which is an enclosure containing the cooling and heating elements,

together with fans for air circulation

HEC1, which contains the power supply and control functions for the HEF1.

7.2 HEF1 FunctionsThe HEF1 (Heat Exchanger Fan 1) contains a heater, heat sink and two sets offans to circulate internal and external air.

7.2.2 Operation

To cool the internal BTS air temperature, external air is blown across the heat

sink outside face. The internal air is cooled by blowing it over the cold inside
