2.1 Operating modes
In normal operation mode the rectifiers deliver the load power taken by the telecom
system and simultaneously maintain the batteries at full charge.
During a line power outage or an excessive line-undervoltage, the rectifiers are shutdown and the batteries deliver the load power.
If the battery voltage decreases below the preset level, the optional deep dischargeprevention circuitry disconnects the battery automatically. As the line power isrestored to a proper level, the rectifiers start up automatically and begin to deliverthe load power and recharge the batteries at current limiting mode.
The batteries are important components in a telecom power system. The control andmonitoring unit is designed to ensure long battery life and effective recharging of the
batteries. Automatic boost charge is based on battery current.
The system level control and monitoring functions include local and remote alarmsand local controls of the system. The local alarms are shown by alarm LEDs.Remote alarms are issued by means of potential free relay contacts.
The operation of the control and monitoring unit is presented in the productdescription of the controller.

2 GENERAL
The rectifier FR 48 V - 2000 W - E is a single phase, hot-pluggable and fan-cooledrectifier. The constant output power characteristic supplies the specified power overthe full output voltage range. The benefit is an optimized modular system design(fewer modules) that matches the supply requirements of state-of-the-art telecomequipment. This performance as well as the extended temperature range, wide inputvoltage range, high power density and advanced technology are the key factors forthe success of this rectifier, offering a cost effective and reliable solution.
The typical applications for this rectifier are both in indoor and outdoorenvironments, which is a perfect solution for wireless base stations, core networkcomponents, telecommunications networks and data networks.
The rectifier meets the requirements set by the telecommunications standards.
The rectifier contains two stages of high frequency power converter (Figure 1.):
The power factor corrector (PFC) has a boost topology with a switchingfrequency of 90 kHz. It is responsible for the power factor and harmonic contentof the input current.
The DC-DC converter has a phase shifted full bridge topology with a switchingfrequency of 100 kHz. It is responsible for galvanic isolation and powerconversion to the DC output.
The control and interface circuit controls and protects the rectifier during alloperation conditions appearing in a power system. The EMC filters guarantee therequired standards.

3.2 Inrush current limitation
When the rectifier is first connected to the mains, the energy storage capacitors are
charged via resistors. As soon as a certain voltage limit is reached, these resistorsare short-circuited, the rectifier starts up and delivers output power.
3.3 Output characteristic
The rectifier has a constant output power characteristic to meet the demand ofoptimal use of the power supply to electronic constant power loads. The result is aconstant recharging current to the battery after a mains outage, and a better use ofrectifier efficiency.

7.4 Defining the system characteristics
The system parameters are the basic characteristics of a power system, such aspolarity, rectifier communication type and nominal voltage. These parameters are
set at the start of the PSC 3 configuration and can not be modified there after.Step 1. Open your web browser and connect to the PSC 3 with the IP address
set earlier (chapter 6.3 ). Log in to the PSC 3 Configuration andSupervision Tooland go to menu:
ConfigurationSystem CharacteristicsSystem Parameter
Step 2. Choose the correct polarity of the system e.g. Positive Polarity,
Step 3. Choose the correct rectifier bus type e.g. digital,
Step 4. Choose the correct nominal voltage of the system e.g. 48 V,
Step 5. Save the settings. Go to menu:
Configuration Setup UpdateClick on Save in the User Setup section of the window.
Note! Save the settings always after making changes to the parameters. If thesettings are not saved, they will be lost after rebooting the PSC 3. Tosave the settings do as above in the Step 5.
7.5 Defining the system architecture
The settings for system architecture define the battery and load shunts in the systemfor the PSC 3, as well as the rectifier grouping and setup. In the followinginstructions the shunt names are based on the Figure 14.
7.5.1 Battery shunts
The settings for battery shunts are located in the menu:
ConfigurationSystem ArchitectureBattery Setup
Step 1. Define the correct battery string type from the drop down menu and clickon the Add button.
Step 2. A window with battery string settings opens. Give the nameBattShunt1 for the first battery string (see the Figure 14). Then definethe battery capacity and the maximum battery current limit Max. Ibatt.Then click on Add Battery String.
Step 3. Define and set values for as many battery strings as in the system, usingthe naming BattShunt2, BattShunt3 etc.
Step 4. Create an additional battery string BattLVD as above. This string iscreated only to drive the LVD relay. The LVD for the batteries is set later.
Note! After a battery or load string is created, the PSC 3 creates automaticallya LVD event, which is later used to drive the LVD relay. The name of theevent is based on the battery or load string name, having an additionalprefix L, e.g. L BattLVD or L PLD1
Step 5. When you are finished click on the Accept changes.

Step 4. Create additional load strings for each PLD in the system as above,using the naming PLD1, PLD2 etc. (see the Figure 14). These strings
are created only to drive the LVD relays for the PLDs that are set later.Step 5. When you are finished click on the Accept changes button.
7.5.3 Rectifier setup
ConfigurationSystem ArchitectureRectifier Setup
Step 1. Define the threshold value for the number of failed rectifiers that issue anUrgent Alarm, and then the value for the number of failed rectifiers thatissue a Non Urgent Alarm.
Step 2. When you are finished click on the Accept changes button.
7.5.4 Rectifier grouping
Note! The menu RM Grouping is for defining rectifier groups and rectifiergroup settings. In the current version of the PSC 3 software the settingsare allowed for only one rectifier group (RFMGroup1).
ConfigurationSystem ArchitectureRM Grouping
Step 1. Go to the menu RM Grouping and click on Edit button of theRFMGroup1. Set the following values for the rectifiers:
Default Values: Voltage, Current Limit, Power LimitThese values define the behavior of the rectifiers if communication to PSC 3 cannot be established.
Input Voltage Limits: Input Low Off and Input Low OnThese values are the AC input On/Off voltage limits.
Startup Parameters: Voltage, Current Limit, Power Limit, Powerup delay, LimitTime.These are the startup parameters for the rectifiers that are saved in the PSC 3,and therefore are used only if the PSC 3 is in connection with the rectifiers.
Group Settings: LastThe value of the first and last rectifier in the group. In the current version of thePSC 3 software only one rectifier group can be defined and therefore the valuefor Last is the number of rectifiers in the system.
Step 2. When you are finished click on the Accept changes button.
Step 3. Save the settings.

7.6 Defining the IMBUS components
The next phase is to define existing physical connections of the IMBUS componentsfor the PSC 3. The components are such as the SENSN devices, String Sensor
Modules (SSM), rectifiers and User Interface Modules (UIM). The UIM, SSM andrectifiers are recognized automatically by the PSC 3, but SENSN devices have to bedefined manually.
The SENSN devices are usually connected to SSM interfaces 1-3 or directly to thePSC 3 (check from the wiring diagram). In the following instructions the SENSNdevices for one load shunt and two battery shunts (see the Figure 14) are defined tothe SSM1 interfaces 1-3. In case there are more battery or load shunts, there is anadditional SSM module (SSM2) in the system.
The SENSNs are defined to the SSM interfaces in the menu:
ConfigurationBus ComponentsSENSN
Step 1. To define the SENSN for the load shunt 1 choose the Bus Name:SSM1 from the first drop down menu and address 1 in the next dropdown menu. Then click on Add SENSN.
Step 2. To define the SENSN for the battery shunt 1 choose the Bus Name:SSM1 from the first drop down menu and address 2 in the next dropdown menu. Then click on Add SENSN. And finally define the SSM1interface 3 for the battery shunt 2.
Step 3. Save the settings.
7.7 Defining the measurements
The next step is to set the necessary measurements and their threshold values inthe system. As default the PSC 3 creates measurements for the system voltageUsys and battery temperature Tbatt. The load and battery fuse measurementsare created next.
The measurements are set in the menu:
ConfigurationSignal Processing EngineMeasurements
Step 1. Give the name Ufuse_Lshunt1 for the load fuse measurement,and choose the signal type digital from the drop down menu.Then click on Add button.

7.8 Defining the events
The next phase is to create the user defined events based on the measurements.These events can be later further processed and used for other events, as well as
for logging and alarms. The following instructions define and set the most importantevents:
The events for too low and too high system voltage
The events for too low and too high battery temperature
The event for too high system power
The event for battery LVD, based on voltage
The events for load PLD, based on voltage
The events are defined and set in the menu:
Configuration
Signal Processing Engine
Event Definitions
7.8.1 Events for too high and too low system voltage
Define first the maximum and minimum threshold values (events) for systemvoltage. The PSC 3 creates as default the event S Usys low, based on measuredsystem voltage Usys.
Step 1. To create a maximum threshold value for the system voltage click onEdit button next to S Usys low.
Step 2. A new Threshold Editorwindow opens. Write the name of the new eventUsys high to the TooHigh Eventfield. Then define the Upper Limitforthe system voltage and if needed adjust the values for the Hysteresis
and Lower Limit. Then click on Change Definition and go back to eventdefinitions window.
7.8.2 Events for too high and too low battery temperature
Define next threshold values (events) for high and low battery temperature, basedon the battery temperature measurement Tbatt.
Step 1. Choose first the measurement Tbatt from New Signal Event, and thenclick on Add.
Step 2. A new Threshold Editorwindow opens. Give the names Tbatt highand Tbatt low for the TooHigh Eventand TooLow Event. Then define
the temperature limits for the Upperand Lower Limit, and define theHysteresis as well. When done, click on Add Definition and go back tothe Event Definitions menu.
7.8.3 Event for too high system power
Define a threshold value (event) for too high system power.
Step 1. Choose first the measurement Psys from New Signal Event, and thenclick on Add.
Step 2. A new Threshold Editorwindow opens. Give the name Psys high forthe TooHigh Eventand then give values for the Upper LimitandHysteresis. When done, click on Add Definition and go back to the

7.8.4 An event for the battery LVD
Define an event for the battery LVD based on system voltage, which is used to drivethe LVD relay for the batteries. Only one event is needed for all battery strings.
Step 1. Choose first the measurement Usys from New Signal Event, and thenclick on Add.
Step 2. A new Threshold Editorwindow opens. Give the name LVD for theTooLow Eventand then give the voltage value for the Lower LimitandHysteresis. When done, click on Add Definition and go back to eventdefinitions window.
Step 3. Now there is an event to drive the battery LVD relay. This event must beassigned to the battery string BattLVD, which was created in thechapter 7.5.1. Go to menu:
ConfigurationSystem ArchitectureBattery Setup
Step 4. Click on the LVD button of the battery string BattLVD, and choose theevent LVD from the Eventdrop down menu. Click on AcceptChanges button.
7.8.5 Events for the load PLDs based on voltage
The Partial Load Disconnects (PLD) for separate load groups are primarily drivenbased on time thresholds from mains failure (see Figure 14). The PLD events basedon system voltage are secondary conditions, to add low system voltage thresholdsto the PLD functionality. Define next the voltage based events for all PLDs. Theevents are later combined with the time threshold events and then assigned to drivethe PLD relays in the PSC 3.
Step 1. Choose first the measurement Usys from New Signal Event, and thenclick on Add.
Step 2. A new Threshold Editorwindow opens. Give the name PLD1 [U] forthe TooLow Eventand then give the voltage value for the Lower Limitand Hysteresis. The recommendation is to use a hysteresis value whichis, together with the Lower Limit, 1 V below Ufloat voltage. When done,click on Add Definition and go back to event definitions window.
Step 3. If needed, define the events for rest of the PLDs in the system as above,using the naming PLD2 [U], PLD3 [U] etc.
Step 4. When all necessary events have been defined and set, click on Accept
Changes.
Step 5. Save the settings.
7.9 I/O assignments of the SENSNs
The next phase is to assign the load and battery fuse measurements from theSENSN devices to the correct SSM interfaces (see chapter 7.7 )..
Normally the SSM interfaces are used in the following way (check the wiringdiagram):
SSM1 interface #1 SENSN for the load shunt 1
SSM1 interface #2 SENSN for the battery shunt 1
SSM1 interface #3 SENSN for the battery shunt 2

The SENSN measurements are assigned in the menu:
Configuration I/O SENSN
Step 1. Choose LoadShunt1 for the SSM 1, address 1 from the drop down
menu. Then click on Edit by the string assignment. In the new SENSNInput Setup window, define the nominal current of the shunt (Value), andthen define the fuse measurement Ufuse_Lshunt1 as the additionalfuse measurement. The temperature sensor is normally connected toload SENSN and therefore define also the temperature measurementTbatt as the additional temperature measurement. Click on AcceptChanges, and go back to previous window.
Step 2. Choose BattShunt1 for the SSM 1, address 2 from the drop downmenu. Then click on Edit by the string assignment. In the new SENSNInput Setup window, define the nominal current of the shunt (Value), andthen define the fuse measurement Ufuse_Bshunt1 as the additional
fuse measurement. Click on Accept Changes, and go back to previouswindow.
Step 3. Choose BattShunt2 for the SSM 1, address 3 from the drop downmenu. Then click on Edit by the string assignment. In the new SENSNInput Setup window, define the nominal current of the shunt (Value), andthen define the fuse measurement Ufuse_Bshunt2 in the additionalmeasurements. Click on Accept Changes, and go back to previouswindow.
Step 4. Click on Accept Changes.
Step 5. Save the settings.
7.10 Event processing and alarms
All events (system and user defined) defined in the PSC 3, can be combined toother events and alarms using the boolean logic (AND, OR, Inversion) and otherbuilding blocks (Filter). The event processing is set in the menu:
ConfigurationSignal Processing EngineEvent Processing
7.10.1 Event processing and assignment for the load PLDs
The primary drivers of the PLD relays are delay based events. These events have atime threshold, which is a delay from mainsfailure to disconnect a load group. Withdifferent time thresholds separate load groups can be prioritized for different loads.
In the chapter 7.8.5 some voltage based events were created as secondarycondition for the PLDs. The event processing feature enables combining the voltageand time based events as one event, which is then used to drive the PLD relays.
Step 1. First the new time filtered event must be created for the load PLDs.Choose the event type Filter from the drop down menu, and click onAdd button.
Step 2. A new Filtered Eventwindow opens. Give the name PLD1 [t] for thenew event and choose the event S Mainfailure from the drop downmenu as a base for the time filtered event. Then define the TRUEandFALSEtime thresholds. The TRUEvalue is the delay for the event to beactivated after mains failure. The FALSEvalue is the delay for the event
to be deactivated after mains is back on. When done, click on the AddNew Definition button.

24 September 2004 27
Step 3. Define as many time filtered events as there are PLDs in the system(Figure 14), using the naming PLD2 [t], PLD3 [t] etc.
Step 4. Now the voltage based events and time based events of the load PLDs
need to be combined as OR events, which means that one of theevents need to be true to activate OR event. Add a new OR event,give the event the name PLD1 [U + t] and choose the events PLD1[U] and PLD2 [t] as a base for the new event. When done, click on theAdd New Definition button.
Step 5. Define as many combined events as there are PLDs in the system(Figure 14), using the naming PLD2 [U + t], PLD3 [U + t] etc.
Step 6. Now the necessary events to drive the load PLD relays exist. Theseevents must now be assigned to the additional load strings PLD1,PLD2 etc., which were defined in the chapter 7.5.2. Go to menu:
ConfigurationSystem ArchitectureLoad Setup
Step 7. Click on the LVD button of the load string PLD1, and choose theevent PLD1 [U + t] from the Event drop down menu.Click on Accept Changes button.
Step 8. Assign the PLD [U + t] events to the respective additional load strings(PLD2 [U + t] PLD2 and PLD3 [U + t] PLD3 etc.).
Step 9. Save the settings.

7.10.3 Special mode event
To indicate that there is some special activity in progress in the power system acombined OR event called Special mode is created next. This event combines all
the events that are wished to be signaled as special activity in the system by the fifthLED in the UIM and by the fifth symbol in the web GUI.
Step 1. Create a new OR event by choosing the event type OR from the dropdown menu and by clicking the Add button.
Step 2. Give the name Special mode for the new OR event and then choosethe events that you wish to be signaled as special activity in the system.Recommendation is to add the battery charging events S EQ inProgress (equalize) and S BC in Progress (boost charge). Add alsothe battery test event S BT in Progress.
Step 3. Accept the new event by clicking on Add New Definition.
7.10.4 A delayed mainsfailure alarm
With Event Processingit is also possible to create delayed events e.g. for mainsfailure. These types of events are useful for example when momentary (very short intime) mains failures are not wished to be signaled as remote alarms (I/Oassignments of the PSC 3).
Step 1. To create a time filtered event choose the event type Filter in the dropdown menu and click on Add.
Step 2. In the new Filtered Eventwindow give the name MF delay for the newevent and define the S Mainsfailure event as a base for the new event.Then set the delay time (TRUEvalue) and click on Add New Definition.
Note! Later the MF delay can be used as remote alarm for the digital outputof the PSC 3 controller.
7.10.5 Adding other events
To add a new event:
Step 1. Choose event type (AND, OR, Inversion or Filter) and click on OK.
Step 2. A new window opens. Give a name for the event and then chooseconditions (events or time filters) for the new event.Then click on Add New Definition and go back to the event processing.
Step 3. Save the settings.

7.11 Alarm setup
In the Alarm Setup menu it is possible to add events as alarms. Only the alarms canbe inhibited with the Alarm Stop button. The alarm stop functionality requires also
activation of the function for each alarm in the Maintenance menu (s. chapter 7.15 ).As default the Urgent Alarm and Non Urgent Alarm are defined as alarms, eventhough they are not visible in the list. The alarms in the Alarm Setup list are alsoused for the I/O assignment in the PSC 3 digital outputs, to signal remote alarms.The alarms that are defined in the Alarm Setup will automatically receive a prefixA, which appears in the menus where events and alarms are assigned. It isrecommended to add at least the mains failure alarm with delay (MF delay) orwithout delay (S Mainsfailure) to the list.
Only events that have been defined as alarms can be seen in the user interfacemodule (UIM) as a source of alarm. Therefore it is recommended to add all criticalsystem events (fuse alarms, load disconnects, battery disconnects, battery
temperature events etc.) to the alarm list. Otherwise they will be indicated only asUA or NUA alarms, without further information about the alarm source. The alarmsource investigation can then be done only through the web user interface of thePSC 3 controller.
The Alarm Setup menu in located in:
AlarmSetup
Step 1. From the new Alarm Setup window choose the event MF delay fromthe Non-Alarm Events, then click on Add >>. The MF delay eventappears in the Deleteable window.
Step 2. Add other events as above.
Step 3. Save the settings.

7.12 I/O assignments of the PSC 3
The PSC 3 has four digital outputs on the front panel for signaling alarms (e.g. NUA,UA and Mains Failure), and two digital inputs for measurements. Assigning the
digital outputs for remote alarms is done in the menu:
ConfigurationI/OPSC3
Note! The recommendation is to use only the events with prefix A(e.g. A S Urgent Alarm) for the digital outputs. The prefix A meansthat the event is an alarm and can be inhibited as remote alarm withAlarm Stop button (see chapters 7.11 and 7.15 ).
Note! When an alarm with prefix A is defined for an output relay, the relay isin the position NO (Normally Open) when the alarm is not active and inthe position NC (Normally Closed) when the alarm is active. For the
events the relay positions are in the opposite way.
Step 1. Choose an event for output OUT 1 from the drop down menu;recommendation is to set UA alarm (A S Urgent Alarm) for this output.
Step 2. Choose an event for output OUT 2 from the drop down menu;recommendation is to set NUA alarm (A S Non Urg Alarm) for thisoutput.
Step 3. If needed, choose an event for the output OUT 3, e.g.A S Mainsfailure or A S MF delay if the momentary mains failures arenot to wished to be signaled as remote alarms (see chapter 7.10.4).
Step 4. If needed, choose an event for the output OUT 4, e.g. S Alarm suppr.,which indicates the system mode when alarms are suppressed.
Step 5. If needed, choose measurements for the inputs IN 1 and IN 2 to use forevent processing.
Step 6. Save the settings.
7.13 I/O assignments of the SSM
The SSM has three digital outputs for signaling LVDs and four digital inputs formeasurements. The assigning of the output relays for the battery LVD and loadPLDs is done in the menu:
Configuration
I/O
SSMStep 1. All String Sensor Modules in the system can be seen in the SSM
Overviewmenu. To assign the inputs and outputs for a SSM click on theEdit button next to the SSM Imbus ID.
Step 2. A window SSM I/O Setup opens. First are the input assignments IN 1-4.The next assignments are for the outputs OUT 1-3. Assign the outputsfor the battery LVDs and load PLDs. Normally the outputs are used inthe following way:OUT 1 Battery LVDOUT 2 Load PLD 1OUT 3 Load PLD 2
