General description

Note

Note

The battery matt heaters are also supplied from Line 3.

The DC supply produced by the rectifiers (nominally 54 VDC) is then distributedby the ADUA or ADUB to the connected loads (batteries, DC loads and the LTEBox equipments (determined by customer requirements). Should the AC mainsfail, the ADUA or ADUB provides a battery supply to the loads for a durationdepending on the DC load and battery capacity.

The distribution will vary depending on the configuration

2.2 CCUA operation

The CCUA is a programmable unit and provides control and monitoringfunctions. The functions effected by the CCUA are as follows:

• management of the Site Support cabinet or Integrated Battery Backup Unit(IBBU)

• battery and power management. Should the AC mains fail, the CCUAcauses the system to enter the battery back-up mode of operation. Duringthis condition, the level of battery output voltage is monitored for battery‘low alarm level’ and ‘low level disconnect’ and appropriate actionundertaken by the CCUA should either event become present.

• climatic control. The temperature within the cabinet is monitored and thespeed of the fans (controlled by the temperature of the rectifiers) is adjustedaccordingly to maintain the temperature within specific constraints.

• alarm reporting. An alarm is generated by the CCUA should an alarm stateprevail and this is sent to the base station via the Q1-bus.

• serial number and version reporting of CCUA, rectifiers and LTE x units

During operation of the UltraSite Support, the CCUA monitors and providesfunctions and controls. Should a failure occur in the UltraSite Support, the CCUAgenerate an alarm which is transmitted to the base station via the Q1-bus. If thefailure is an AC mains failure then the CCUA places the Support system into theBattery back-up mode.

There are three modes of operation and these are described in the followingsections.

Battery back-up mode

In this mode of operation, the batteries provide the DC power requirements of theSupport system and the base station.

During this time, the CCUA monitors the DC voltage level and should the levelfalls to the battery low level parameter, a Battery Low alarm is raised. If the DCvoltage level continues to fall and goes below the Low Voltage Disconnect(LVD) level, the CCUA disconnects the battery supply from the load via the LVDrelay. This condition is maintained until the Support system DC voltage is above50 V then the batteries are reconnected.

Site support mode

This mode is entered when the CCUA detects that the Support Mode is active.The mode is used to manually or automatically effect a battery test.

During this mode of operation, the CCUA reduces the rectifier (BATA) output tothe level of the Support Mode level. The whole DC power is then taken from thebatteries.

Normal operation is resumed when the tests have been completed satisfactorilyand the Support Mode signal disappears.

Boost charge mode

The CCUA monitors the status of the batteries to determine whether or not boostcharging of the batteries is required. This can be done on a periodic basis or whenthe batteries have been discharged below a set DC value (automatic).

The maximum boost charge duration is 2 hours after which time, normal systemoperation is resumed. Periodic boost charging does not occur unless 16 weeks(user determined) have elapsed since the previous boost charging had beencarried out. Also, if the battery temperature is equal or in excess of +30ºC.

During battery charging, the current level is monitored and maintained within setlimits by the CCUA.


General description

2.2.1 Unit fan: rectifier internal temperature compensation

The CCUA monitors the internal temperature (once a minute) of the rectifier unitsand controls the unit fan speeds accordingly; 1 fan unit/2 rectifiers. Control of theunit fan speed is realised according to the warmer rectifier and adjusted until thecooler rectifier cools down to a level at which juncture the fan is switched OFF.

The unit fan speed is set to a minimum if the temperature information from bothassociated rectifiers is missing.

The temperature of the rectifiers is measured once a minute by the CCUA and isundertaken by software control

The unit fans are switched off if the temperature of the rectifier units is below theset level (+10ºC) and switch on when the temperature is above this level. The unitfan speed increases from 40% (PWM signal 25%) to 100%. The relationshipbetween the PWM and fan speed is a straight line function. The following Table2gives some figures:

When PWM control is < 20% and fan control is > 80%, the fan is stopped.

The CCUA generates an alarm should a fan stop rotating and an alarm if rotationof a unit fan is too slow compared to the PWM signal (see Alarms 3.2.3.

The fan speed is also dependent on the supply voltage. The CCUA checks that thereduced fan speed is not attributable to reduced voltage by comparing the rotationspeed (rpm) measurements with other fans. An alarm is activated if the other fansare rotating at the desired speed (see Alarms 3.2.3.

The fans can be controlled separately for test purposes

60 40 70

40 60 50

20 80 35



2.2.2 Cabinet fan 1 (Support cabinet)

The cabinet cooling fan is used exclusively in the outdoor UltraSite Supportcabinet. The maximum speed of the cabinet fan is 75% of rated value to reducethe noise level but without diminishing the effect of the airflow.

This fan is controlled in the following manner:

• Speed of fan is the same as the speed of the slowest unit fan except whenthe unit fan speed is 100% when the cabinet fan speed is then 75%. Whenthe speed of the fastest unit fan goes below 100%, the cabinet fan speedreduces its speed to the slowest unit fan speed in a stepped manner (10%change/1 minute. If one unit fan is controlled OFF, the cabinet fan is alsocontrolled OFF (except if the other unit fan is rotating at 75% speed)

• Fan is controlled OFF if cabinet heater is ON

• Fan is controlled OFF if the cabinet door is OPEN.

• Fan is controlled to FULL speed when the battery temperature HIGH alarmis ON and the batteries are in the cabinet

The CCUA generates an alarm should a fan stop rotating and an alarm if rotationof an unit fans is too slow compared to the PWM signal (see Alarms Chapter3.2.3).

The fan speed is also dependent on the supply voltage. The CCUA checks that thereduced fan speed is not attributable to reduced voltage by comparing the rotationspeed (rpm) measurements with other fans (to unit fans in case of cabinet 1 fan,and to cabinet 1 fan and unit fans in Support cabinet in the case of cabinet 2 fan).An alarm is activated if the other fans are rotating at the desired speed (see Alarms3.2.3.

The fans can be controlled separately for test purposes

2.2.3 Cabinet 2 fan (in extension cabinet - battery cabinet)

The cabinet cooling fan is used exclusively in the outdoor UltraSite Supportcabinet. The maximum speed of the cabinet fan is 75% of rated value to reducethe noise level but without diminishing the effect of the airflow.

This fan is controlled in the following manner:

• Speed control is based on the temperature of the battery cabinet. If thecabinet temperature is below the fixed level (+10ºC), the fan is switchedOFF. The fan switches ON when the temperature goes above the fixedlevel. The cabinet fan speed increases from 40% (PWM signal 25%) to75% maximum (see Table in Section 3.2.5).

• Fan is controlled OFF if cabinet heater is ON


General description

• Fan is controlled OFF if the cabinet door is OPEN.

• Fan is controlled to FULL speed when the battery temperature HIGH alarmis ON and the batteries are in the cabinet

2.2.4 AC heater operation

AC heaters are used for battery heating.

Heating control is effected by the BOI in the base station for the IBBS cabinet. Inthe case of the Support cabinet and extension cabinet, heating control is done bythe CCUA.

UltraSite Support cabinet

The rectifier internal temperature information is not used to control the cabinetheater.

The CCUA monitors the battery temperature (sensor on the lower batteries) andcontrols the AC heater (s) in the cabinet. If the battery temperature is below theprogrammed level (0ºC), the cabinet heater is switched ON via a relay. When thetemperature goes above the programmed level (10ºC), the cabinet heater isswitched OFF.

UltraSite Support extension cabinet

The CCUA monitors the battery temperature (sensor on the lower batteries) andcontrols the AC heater (s) in the extension cabinet. If the battery temperature isbelow the programmed level (0ºC), the cabinet heater is switched ON via a relay.When the temperature goes above the programmed level (10ºC), the cabinetheater is switched OFF.

2.2.5 Battery cooling interface

The cabinet fans are controlled in the manner described in Section 3.2.5.

The CCUA monitors the battery temperature and when the ‘Battery TemperatureHigh’ alarm is signalled, the cabinet fan is controlled to full speed under thecontrol of the BOI in the case of the IBBU cabinet, and under the control of theCCUA in the other two cases (Support cabinet and Extension cabinet).

2.2.6 Battery test

The batteries can be tested automatically from the CCUA, or manually eitherlocally from the CCUA front panel LMP connector and laptop computer (RS232interface) or remotely from the NMS (Q1-bus; RS485 interface).



Automatic battery testing can be arranged to occur a number of times during ayear; 4 times a year is the usual figure. The period of a test is pre-defined.

The batteries must be in a fully charged state before automatic testing can takeplace. this status is determined by the CCUA.

The ‘Battery Failure’ alarm occurs when the battery output voltage is too lowduring the automatic test. The test is discontinued should the output voltage of thebatteries fall below the ‘Support Mode’ level, and this is the lower level fordischarge of the batteries during automatic testing.

When manual testing of the batteries is taking place, the ‘Support Mode’ level canbe activated locally via a CCUA front panel connector or remotely from the NMS.

During a battery test (automatic or manual), the DC output from the rectifiers isdecreased to the ‘Support Mode’ level. At this time, the power for the load istaken from the batteries.

2.3 Construction

The AC/DC Connection Unit (ADUA or ADUB) is located at the top of the SiteSupport cabinet or at the bottom of the IBBU located in a Nokia UltraSite GSMEDGE BTS cabinet.

The ADUA/B contains the Controller Unit (CCUA) which is a plug-in modulelocated at the front, bottom of the ADUA or ADUB.
