2 General description

2.1 General information

Wherever increased operating safety and high outputs are specified in DC voltage supplyto consumers, the thyristor-controlled rectifier is the most frequent technique employed. Inthe JOVYATLAS "THYRIDYN" model series, the rectifier bridge is deployed in a fully-controlled 6-pulse or optional 12-pulse circuit, depending on requirements. A 12-pulserectifier bridge is recommended whenever increased demands are imposed on the outputvoltage in terms of current and voltage ripple. Another key point is reduction of theharmonic currents from the power company supply network based on the use of 12-pulserectification.The THYRIDIN series comprises the following models:

- supply rectifier VG- charging rectifier LG- uninterruptible DC voltage supply unit UGV

If a secure power supply independent of the power company network is required, thepower supply units must be deployed with parallel-configured batteries. In this case, in theevent of a mains power failure the supply is maintained for a time (the bridging time) bythe battery. These systems are known as uninterruptible power supply (UPS) units,designated here as UVG based on the German abbreviation. The DC voltage supplyconsists of a regulated charging/supply rectifier with a float charge and boost deviceadapted to the battery.If increased demands are imposed, independent of the battery charging voltage, on theconsumer voltage tolerance limits, an optional single-stage or two-stage counter-cell unitis used to stabilize the consumer output.In line with the state of the art in power supply and battery charging technology, the"THYRIDYN" series incorporates an electronic closed-loop and open-loop controller. Theintegrated automatic charger enables users to freely configure the type of chargecharacteristic and the battery charging voltage and current based on a menu-guidedprogram.

2.2 Charging rectifier function

The supply is connected to the charging rectifier on connector block X1.

i

ATTENTION:When connecting the mains supply, ensure clockwise phase sequence!

The transformer (T1) transforms the mains input voltage into a level required for therespective output voltage. The downstream fully controlled thyristor bridge (A1) rectifiesthe AC output voltage of the transformer into a DC voltage with an overlaid AC voltage

component. The filter combination, comprising a smoothing reactor L1 and a smoothingcapacitor C1, reduces the output voltage ripple due to the operating angle.All the components required for rectifier operation and monitoring of those componentsare mounted on the control board 'P0034201' with the higher-level controller board'P0034001.


9/73



2.3 Functions of the individual modules

2.3.1 Thyristor module

The fully controlled thyristor bridge rectifies the AC output voltage of the transformer into a DC

voltage with an overlaid AC voltage component. According to the phase angle of the thyristors,the output voltage or output current is regulated by way of the control board (A2).The filter combination, comprising a smoothing reactor and a smoothing capacitor, reduces theoutput voltage ripple due to the operating angle.Super-fast fuses are connected upstream of the rectifier thyristors. They protect the thyristors inthe event of a short.The fully controlled thyristor bridge used is equipped with a thermo-switch and a fuse monitor.Overheating or fuse failure results in immediate shutdown of the rectifier.

2.3.2 Control board

The control board is the interface between the higher-level controller board (A2) and the rectifierpower circuit. On it, all measurement data such as currents, voltages and temperature arescaled and delivered to the controller board for further processing.

2.3.2.1 Control electronics modules

- Phase control electronics with pulse driver output stagesfor phase control of a 6-pulse thyristor module, including interface for expansion to 12-pulserectification

- Interface/signal relaysK1 for rectifier ON/OFF , K2 and K3 for the 1-stage or 2-stage counter-cell control options,K3 for the flat-battery monitor option.

2.3.2.2 EMERGENCY RUNNING switchover (optional)Depending on the application, in the event of a fault in the microprocessor control anautomatic switch is made to 'emergency running' mode. In this case, the rectifier continues

operating with the pre-set basic current and voltage settings. With this option, it is alsopossible to switch to emergency running mode manually by way of an additional switch in therectifier cabinet. In emergency running mode, an updated firmware version can bedownloaded without interrupting the battery charge or the supply to the consumers forexample.

ATTENTION:In emergency running mode an installed counter-cell unit (optional) isshorted. In UPS systems the basic setting for emergency running must neverbe greater than the maximum operating voltage permitted at the consumer!


11/73



2.3.2.3 MonitorsIn addition to a large number of parameters monitored by the microprocessor controller, thefollowing values are monitored by hardwareon the control board:

- Rotating field faultThe supply system is monitored for clockwise phase sequencing. If an anti-clockwise

phase sequence is detected the start phase is locked. The phase control and thus theoutput voltage of the rectifier is disabled. The phase angle of the mains feed must berotated!

Signalling on control board: red LED V61 litSignaling via panel: "Please check rotating field"

- Phase faultActivated in event of phase fault or mains voltages < 70%/Urated. In the event of a fault,disables phase control and thus the output voltage of the rectifier. The supply rectifier(VG) and charging rectifier (LG) can only be restarted after switching the rectifier off andback on. In the case of uninterruptible DC power supply units, an autostart is executedwhen the mains power is restored.

Signalling on control board: green LED V75 offSignalling via panel: "Phase fault" display and red "fault" LED

- DC high voltageIf the internal rectifier voltage exceeds the maximum threshold value pre-setpotentiometer R133, the phase control is immediately disabled and the output voltage ofthe rectifier thus locked. A serious fault has occurred. It can only be reset by pressing theRESET key S1 on the control board or switching the rectifier off and back on.

3.4.1.4 Current-dependent boost stage setting (optional)

The current-dependent boost stage (IUU/ I-characteristic) is an extension of the standard boost stage (IUUcharacteristic). Here, the switch back to float charge is not made on reaching the boost voltage but only oncethe battery charging current falls to a pre-set value. The most frequent application is in charging of NiCdbatteries to shorten the time until the maximum battery capacity (full charge) is reached.

As this value must not be greater than the maximum battery charging current setting, the setting is made as apercentage dependent on the configured battery charging current.

The time-dependent boost stage (IUU/ T-characteristic) is an extension of the standard boost stage (IUUcharacteristic). Here, the switch back to float charge (EL) is not made directly on reaching the boost voltagebut only once a pre-set time has elapsed. The most frequent application is in charging of NiCd batteries inconjunction with the "current-dependent boost stage". If current- and time-dependent charging stages are seton the "Mode" menu, on reaching the pre-set current the current-dependent boost stage timer is activated.When the pre-set time elapses the switch is made to float charge.The time-dependent boost stage setting is freely configurable from 1 to 360 minutes.

charging stage alternately with the measured values. In our above configurationexample the outputs "Boost IUU" and "Boost IUU /I /T".(The voltage-dependent boost stage IUU current- and time-dependent is active)

3.4.5 Capacity test mode

It is possible to perform a battery test and so rate the connected battery. The test is started from the "Modes"menu.

i

NOTE:

If the capacity test is activated during a boost charge, it is automatically startedonly once the boost is complete, and provided the external control contact toenable the capacity test is closed. The control contact is connected to X5 5/6(optional).

Description:In a battery test the output voltage of the charging rectifier is reduced so that the connected consumers arebeing powered solely by the battery. The panel indicates "Capacity test active", with the battery dischargetime.The switch-off condition is the end-point voltage. When the end-point voltage falls below the minimum, thesystem switches automatically back to battery power. A result notification is only outputted if the minimumend-point voltage is infringed before the discharge time is reached. The display then shows: "Cap.testnegative", the red "fault" LED lights up and the acoustic signal generator sounds. The message is reset by

way of the "RESET" key . If the capacity test is positive, no result output is generated.

Default settings:The end-point voltage and discharge time are factory preset according to the battery manufacturer'sspecifications with regard to the maximum consumer current (rated load). The settings can be adjusted toactual on-site conditions on the "Change battery data" menu. See "Discharge time setting" and "End-pointvoltage setting" sections.

i

NOTE:

If the capacity test is specified exactly at rated load, and if the required loadcannot be simulated locally by the connected consumers, JOVYATLAS cansupply load resistors.

Selection options:On the "Modes" menu users can choose between two modes for execution of the capacity test:1) If only the "Capacity test"option is selected on the "Modes" menu, the test is only ended once the end-point voltage has been reached. The battery is fully discharged.2) If "Capacity test" and"Discharge time" are selected on the "Modes" menu, provided the minimum end-point voltage has not been infringed beforehand the test is ended when the discharge time is reached.

4 Computerized operation

4.1 RS232 interface

The RS232 interface of the rectifier is mounted inside the unit. It permitsoperation of the rectifier from an external computer. For this, the computer isconnected to the rectifier by way of a cable.The technical data of the cable:9-pole with SUB-D9 connector (1 x male, 1 x female)Wiring: 1 : 1

The interface of the external computer is set to:

9600 Baud 8N1, no hardware handshake

Required software: A terminal program such as has been shipped with everyoperating system since 1995.

The serial interface is used in the following to:

- read the ongoing rectifier data- read out the status/fault memory- download/upload factory parameters- download/upload customer parameters- shut down the rectifier- transfer a manually measured temperature- query the rectifier software version- set the system time and date- output error messages in the event of incorrect queries- reset fault messages/acoustic signal generators

Some of these functions can be initiated by way of the terminal program:The commands for this are included in the detailed description, together withexamples.

As soon as the rectifier is switched on, the current measured values anddevice configurations are transferred via the rectifier's RS-232 interface anddisplayed on-screen in table form.The measured values are updated every second. This output is intendedsolely for the service technician, to provide a rapid overview of the currentmeasured values and setpoint inputs for ongoing operation.Continuous output of the momentary measured values and setpoint inputscan be blocked by way of a DIP switch on the controller board P0034001.

Outputs then only appear following command inputs.DIP switch array (S2) DIP8=ON

4.4.4.4 Upload operating mode

Here the desired modes for battery charging or discharging can be set. All modes can beactivated via menu (see "Menu" section) or PC terminal. Active modes are indicated alternatelywith the measured values on the rectifier display.Setting mode/charging characteristic via PC terminal:To set multiple modes simultaneously, they have to be added together. This is necessary, forexample, when the boost stage is to be reactivated after equalization charging or a capacity test.

The modes have the following significance:Boost IUU : 1IUU current-dependent : 2IUU time-dependent : 4Equalization charging : 8Capacity test : 16Discharge time : 32Example: after the capacity test the current-dependent and time-dependent boost stage is to bereactivated.Composed of the significances for:Boost IUU = 1IUU current-dependent = 2IUU time-dependent = 4

Capacity test = 161+2+4+16=23
