I. GENERAL DESCRIPTION

1.1 Introduction

VISION DSP0.9 Series Uninterruptible Power Supplies are double-conversion; on-

line UPS’s manufactured with the latest IGBT and PWM technology, to produce an

uninterruptible, fully DSP (Digital Signal Processor) controlled pure sine wave output to critical loads.

VISION DSP0.9 Series units are 3-phase in/3-phase out devices, and they are installed between a three phase critical load, and a 3-phase+N mains supply

The advantages of using DSP0.9 UPS:

 Power blackout protection:

If the mains power fails, the UPS continues to supply the critical load using the energy stored in its batteries, keeping the load immune from power disturbances.

 Increased power quality:

The UPS has its own internal voltage and frequency regulating software, which ensures that, its output to the critical load is maintained within close tolerances, independent of voltage and frequency variations on the mains power lines.

 Fully digital control by three DSP controller for each UPS:

The UPS is controlled by 3 independent DSP chips which are communicating each other continuously. Rectifier, Inverter and User Interface modules have separate DSP’s to achieve the highest performance. Each DSP module has many parameters to control and monitor the system to have the best electrical power output and to help diagnostic.

 Increased noise rejection:

By rectifying the input AC power to DC power and then converting it back to AC (Double-Conversion) any electrical noise present on the input mains supply line is effectively isolated from the UPS output. Therefore the critical load is supplied with only clean and uninterrupted AC power.

1.2.1 Description of Blocks

RECTIFIER: In DSP0.9 Series UPSs, a DSP controlled IGBT rectifier with PWM technique is used to

increase input power factor (PFC) and to decrease input current harmonics (THDI). The IGBT rectifier accepts 3-phase AC input and produces a dual polarity DC voltage for both supplying the inverter and charging the batteries.

BATTERIES: Batteries are used as reserve DC power supply for the Inverter in case of mains failure. In DSP0.9 Series, batteries are connected in series with a center-tap output to obtain a dual polarity DC supply. Batteries are discharged by the inverter during mains failure. The discharged batteries are re-charged by the IGBT Rectifier on a constant voltage / current limiting basis, if AC mains power is available.

INVERTER: It is manufactured by using the latest IGBT and DSP (Digital Signal Processing) technologies, and Pulse Width Modulation (PWM) technique. The Inverter converts the DC BUS voltage supplied by the IGBT Rectifier and / or the batteries into a well regulated, fully digital controlled 3-phase AC voltage with fixed voltage and frequency. The output of the inverter is used to supply the critical loads connected to the UPS output.

STATIC TRANSFER SWITCH (STATIC BYPASS): This is an electronically controlled transfer switch, which enables the critical load to be connected either to inverter output or to by-pass power source. During normal operation, the load is supplied by the inverter output, but in case of an overload or a UPS failure it is automatically transferred to the bypass source without any interruption.

MAINTENANCE BYPASS SWITCH (MBS): This is a manually controlled mechanical switch, which is used to supply the critical load, using the bypass source, when the UPS is shut down for maintenance or troubleshooting purposes. The load is unprotected against mains supply disturbances and black-outs when it is connected to either static or maintenance bypass supply.

1.2.2. Operating Conditions of UPS

UPS may be in one of the following operating conditions:

A. Normal Operation (If Mains supply is available):

All fuses and power switches are closed (except the Maintenance Bypass Switch), and the load is supplied by the Inverter Output. During normal operation, the Rectifier supplies DC power to the Inverter and charges the Batteries at the same time.

B. Battery Operation :

The Batteries are connected to the Rectifier output. In case of a mains failure (mains power outage or AC input voltage out of tolerance), the Rectifier stops operating and the DC voltage necessary for the inverter operation is supplied by the batteries. Therefore the AC voltage output supplying the critical load is not interrupted, until the batteries are fully discharged. At the end of the discharging time the inverter is turned off and it start again automatically, together with the rectifier, when the mains power is restored, and the UPS returns o normal operation. For UPS with a split bypass source, at the end of discharging time, static transfer switch transfers the load to the split bypass source without interruption if the split bypass source is available and in acceptable tolerances about voltage and frequency, as still the rectifier input is not available. The Rectifier is also turned off and inverter operates on batteries during automatic or manual battery test procedure.

C. By-Pass Operation :

If the Inverter output is overloaded or in case of a problem in the UPS, the static switch transfers the load to the bypass supply without any interruption, provided that the bypass supply is available and within the tolerated limits regarding voltage and frequency. At the end of the overloading period, if the fault condition is restored, static switch transfers the critical load again to the inverter output. Note that, during operation from the bypass supply, the critical load may be effected by any possible disturbances or power failure in the bypass supply.

(N2) must always be connected together to form the Neutral of the AC output.

2.7 Battery Installation

WARNING!!! Be careful while connecting batteries. ATTENTION!!! Open the battery switch/fuse before making any connection on the batteries.

The batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet. In DSP0.9 Series 40-60 KVA UPSs, there is enough space for 60 pieces of 12V 7Ah maintenance free batteries.

Where battery racks are used, they should be sited and assembled in accordance with the battery manufacturer’s recommendations. In general, batteries require a well-ventilated, clean and dry environment at reasonable temperatures to obtain efficient battery operation.

In general a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimum clearance of 20 mm should be allowed between the cell surface and any walls. All metal racks and cabinets must be earthed.

1. Unpack each battery and check its terminal voltage with a suitable load. Any battery with terminal

voltage less than 10,5V must be charged before installation.

2. Please check the battery connecting hardware and documents. (cables, trays, connection

diagrams)

3. Please locate suitable number of batteries on each rack, according to the battery installation and

connection diagram given with the unit.

4. Start locating the batteries from top to the bottom on the racks.

5. Be careful about the connection between the racks and polarities.

6. After interconnecting the batteries, connect “+”, “0” and “-“ leads of the batteries to the battery

input terminals on the UPS. Be careful to connect the batteries correctly and do not turn on (S5) before checking all connections and before starting the UPS. In DSP0.9 Series UPS, 60 blocks of batteries are connected in series, in such a way that they form two strings of batteries with opposite polarity; with a center tap connection to the NEUTRAL (N1-N2) internally.

NOTE THAT SEPARATE CABLES FROM EACH BATTERY GROUP SHOULD BE CONNECTED TO K2 TERMINALS TO FORM THE MIDPOINT CONNECTION.

WARNING!!! NEVER TURN ON S5 (BATTERY FUSE) WITHOUT CENTER POINT CONNECTION TO K2.

3.3 Alarms and warning messages

The internal structure of the EF300 Series UPS is modular, these are:

-PFC Rectifier module

-Inverter module

-Front panel module

Module alarms and warnings are cathegorized according to modules at the front of the Alarm or warning message module information is added:

-RXX Rectifier alarms and warnings

-AXX Inverter alarms and warnings

-LXX LCD front panel alarms and warnings

More then one alarm can be shown on the UPS front panel with time shared order. If 4 alarms are occurred at the same time every 2 seconds 1 message will be showed, next 2 seconds 2.message will be showed etc.

If A00 or R00 Alarm is shown on the LCD panel we understand that there is a system fault at the related module. We saw the message in the A00 INV FAULT = XXXX or R00 PFC FAULT = XXXX format. Numbers shown in X determines the status code which tells the problem to us. See status code table for details of codes.

IV. PARALLEL OPERATION

4.1 Introduction

Two (or more) identical DSP0.9 series UPSs can be interconnected for parallel operation. The main purposes for parallel use of DSP0.9 series UPSs are:

-Redundancy for Increased Reliability

-Power Increase Although recent UPS designs are perfect and have high MTBF figures, a second (or more) UPS

can be used in parallel with the first one, for supplying the critical load in case of any possible failure of the first UPS. In such an application the faulty UPS is isolated automatically from the parallel system and the other UPS (or UPSs) continues to supply the critical load. Use of Redundant UPSs in parallel, therefore, provides increased reliability for the critical load connected to the parallel system output.

If power demand increases in a certain UPS application exceeding the power rating of an already installed stand-alone UPS, a second (or more) UPS of the same model and power rating can be added in parallel to the existing UPS to increase the output power capacity.

Schematic diagram of parallel connection of two DSP0.9 series UPS units is shown in Figure 4.1

The AC inputs of all UPSs in the parallel system are connected to the same mains, and all the AC

outputs are connected to each other. Each UPS has its own battery group. The critical load is connected to the common output of the parallel system. There are also some signal cable connections between the UPS units necessary for parallel operation, and will be described later.

4.2 Parallel Operation Mode settings of DSP0.9 Series UPSs

NOTE: Parallel operation hardware (parallel communication board) are not installed in a standard DSP0.9 series UPS, but parallel operation option is available and can easily be added to all UPSs.

N+1 REDUNDANT parallel operation For parallel operation some parameters must be given by the service personnel these are:

1- Select Parallel mode must be selected from ADJUST MENU (ADJUST MENU/INV FACTORY

OPTIONS/OPERATING MODE:)

2- A unique UPS network no must be given from ADJUST MENU(ADJUST MENU/INV

FACTORY OPTIONS/UPS NO:) (each UPS must be assigned a unique UPS number)

3- Minimum UPS quantity requirement must be given from ADJUST MENU (ADJUST MENU/INV

FACTORY OPTIONS/N+1 MINIMUM:) (N number in the system) Shown parameters can not be adjust by the user, these parameters are located on ADJUST MENU also adjust menu is password protected only authorized service personnel can access this menu.

PARALLEL mode

This mode is used for operation of at least two (1+1 configuration) UPS units connected in parallel for increased reliability. If this mode is selected, the load is shared equally by each UPS available in the parallel system (N+1 numbers of UPS units), during normal operation.

In case of a failure of any one of the UPS units, the faulty UPS is isolated from the parallel system and the critical load is supplied by the remaining N number of UPSs. If any one of those UPS units fails too, then the critical load is transferred to bypass supply via the static bypass switches of the parallel connected UPSs. If the faulty UPS returns to normal operation, it joins the parallel system again and starts sharing the load.

In parallel mode, the total VA rating of the parallel system is equal to the VA rating of a single UPS multiplied by N.

In parallel mode, you will see ‘’PARALLEL MODE /MS’’(master UPS) or ‘’PARALLEL MODE /sl’’ (slave UPS) message on the LCD panels of all UPS units.

More detailed diagrams for two (or more) DSP0.9 series UPSs connected in parallel are given in Figures 4.2 and 4.3

Communication between parallel UPSs are provided over one pair cable (PCC06). The length of the cable is limited up to six meters. A link cable is used for connecting the first UPS to the last UPS ,this cable is redundant for normal communication cables. If communication is lost on SLAVE UPS the UPS will shutdown, but the MASTER UPS will go on running. If the communication is provided at SLAVE UPS, it will start automatically again.

6.1 OPERATING UPS IN ONLINE MODE

Page 55

PREMIUM DSP 40-80 KVA PF0.9 3/3 - UPS www.visionups.com

6.1.4 Switching the UPS from a Maintenance Bypass Condition to Normal Operation

1. Turn on S1 (AC Input) switch (to ‘’1’’ position).

2. Turn on S2 (Bypass) switch (to ‘’1’’ position).

3. Turn on S4 (AC Output) switch (to ‘’1’’ position).

4. Turn on S7 (On/Off) switch (to ‘’1’’ position). LCD panel activates, and main menu will appear at the display. Also “A08 ON MAINTENANCE” message shown and the inverter will not start yet.

5. Turn off S3 (Maintenance Bypass) switch (to ‘’0’’ position). Inverter will start automatically

following the turning off of S3 switch.

6. Connect the batteries by turning on S5 (Battery) switch (to ‘’1” position).

Now UPS is ready for uninterruptable operation.

When the mains voltage is not available " R02 LINE FAILURE " message appears on LCD display. Sound warning on and off is heard at the same time. UPS continues to supply the critical loads by converting the battery voltage to AC voltage and provides operation without data losses or any other fault. Battery autonomy time may be prolonged by shutting down the unnecessary loads for that moment.

But do not turn on these loads again during battery operation. After a short period of time when the line voltage is available again, UPS returns to normal operation

automatically and the alarm message on the display disappears. Shut down the critical loads in a period of minimum possible autonomy time (depends on the Ah

capacity, charge status, age of the batteries, actual load percentage of UPS and the ambient temperature). Otherwise critical loads will be out of power at the end of battery autonomy time.

“A26 BATTERY LOW” message appears first on front panel display during battery operation if battery voltage drops below a defined level.

“A10 BATTERY LOW SHUT” message appears on front panel display when the battery voltage drops to the end of discharge voltage and UPS shuts itself down. Critical loads will be out of electrical power.

If a reserved generator in the system and if it’s available, that will start to supply the necessary electrical power to UPS input and batteries start to be charged immediately. By means of using UPS together with a immediately available generator system, battery discharge time decreases and so they will be charged quickly after a mains outage.

6.2 UPS Behavior During Mains Outage

VII. MAINTENANCE

ATTENTION! There are no parts inside the UPS or battery group that needs service or maintenance

work that should be done by user. Therefore DO NOT OPEN THE COVER OF UPS. Never touch on any terminal of battery group. There is risk of electric shock inside the UPS even when it is completely turned off (because of energy storage components). Therefore unauthorized openning of the UPS cabinet for repairment, maintenance etc. is not recommended and forbidden. Otherwise serious injuries may happen.

7.1 Scheduled Maintenance

Some parts and components used inside UPS requires periodic maintenance by service personnel. Besides, some power equipment inside the UPS need good air circulation for cooling functions. In this case, the UPS should be cleaned against dust periodically. Cooling fans are mechanical and moving parts and they should be checked periodically for this reason. Also the batteries should be checked periodically that if they are in good condition or not.

DSP0.9 Series UPS informs the user about these procedures when the maintenance time is up with its 3 independent hour counter as warnings:

FAN MAINTENANCE counter BATTERY MAINTENANCE counter GENERAL MAINTENANCE counter

This type of protective maintenance prevents small problems turning up to big failures.

DSP0.9 Series UPS has been designed to require very low user maintenance work. User should only make below maintenance procedure for long years of trouble-free operation.

7.2 Daily Checks

Observe the UPS daily and check the following: Examine the operator control panel (front panel). Ensure that all LED indicators and parameter

measurements are normal and there is no warning or alarm messages on LCD display. Examine that there is any sign of overheating the UPS or not. Check the rotation of cooling fans visually. Check if there is a remarkable change in the sound of UPS or not. Check if air inlets of the cabinet cooling system are not congested with dust or any other foreign

object. Clean them with a vacuum cleaner if any present. Take care not to leave any object on the UPS cabinet.

7.3 Weekly Checks

1. Examine the front panel and record the results.

2. Measure (from Measurements Menu) each of three phase voltages and record the values.

3. Measure (from Measurements Menu) UPS output current values and record the values.

4. Perform a Manual Battery Test (from Commands Menu) and check the status oft he batteries.

5. Cabinet covers may be cleaned with a soft damped (not wet) cloth.

Page 57

PREMIUM DSP 40-80 KVA PF0.9 3/3 - UPS www.visionups.com

Take notes if possible when you are examining the UPS. Compare the notes with previous ones and try to determine if there is a change or not. If there is a difference between the previous notes and the new ones, search for and record any new load added to UPS output between two records and the magnitude, place and type of the new load, if possible. This information may help to technical authority who will search for the cause of event in case of a failure. If there is a remarkable difference between the records without any obvious reason, call technical service immediately.

7.4 Annual Maintenance

Annual maintenance by authorized service should be done at least two times a year in order to provide safe and efficient operation your UPS and battery group. UPS generates a warning message when the maintenance time has expired.

7.5 Storage Conditions and Transportation of UPS

1- Check battery charge status by performing a manual battery test before living the UPS in a storage

place. If charge level is not high enough, leave the UPS for at least 12 hours to charge the batteries.

2- Disconnection oft he cables should be done by an authorized service personnel. 3- Batteries should be recharged once every 6 months during storage. 4- Store the UPS and the batteries in a cool and dry place.

Ideal storage temperature for UPS: 0 0C to 40 0C max.

Ideal storage temperature for batteries:10 0C to 35 0C max. 5- UPS should be fixed on its pallet for transporting. It should be carried by a forklift with ist pallet.

VIII. FAULTS AND TROUBLESHOOTING

8.1 General Procedure for Fault Checking and Troubleshooting

UPS contains complicated electronic control circuits. In order to locate any fault occurring circuits, an advanced knowledge about the circuitry and its operation principles must be known. The aim of this section is to give the knowledge required at the first intervention.

There is no practical way to locate any possible fault. Most of the faults do not occur as a performance decrement. Generally, the UPS operates normally or switches into by-pass mode. But in order to determine any change in load or the system the parameters must be recorded regularly as mentioned previously.

Generally, the output voltage can deviate %2 from the predefined values. If values differ more than this percentage then reasons must be investigated.

The following general structure must be systematically followed while trying to indicate the error: Fault determination: First step is to record the messages, indicator panel LEDs, operating

parameter values and last status of switches. This must be done before.

Fixing interventions: After recording all indications, check the meaning of the fault and alarm

messages using “The operator control indicator panel”. If anything related, follow the related procedure.

Reporting the fault: Service personal must clearly report the work done. Hence, if any other error occurs there will be enough information to fix it.

8.2 Before Calling Service

Please check and note the following: 1- Did you read the user manual carefully and applied the procedures accordingly?

2- Are the switches and circuit breakers of UPS in their normal position? 3- Is there electric power at the UPS line connection distribution panel? 4- Did you turn the battery switch on (to “1“ position) when UPS started to operate in normal mode? 5- Which of the warning lights on front panel is (are) on? 6- Is there any change in the load level at the output of UPS? 7- Did any overload condition happen or not?

IX. UPS REMOTE MONITORING AND CONTROL

Following external connections are available for DSP0.9 Series UPSs.

 Communication by serial port connection.  Dry contact (interface board) connections.  Remote monitoring panel.

Using one of above communication options is satisfactory for remote monitoring and control in most of the systems. But in some systems may use 2 or 3 of above options at the same time. In this case accessories group produced by Vision may help to make appropriate solutions.

9.1 Using Serial Port

Two serial communication port is included on DSP0.9 Series UPS cabinet (com1 and com2). Both of them may be used for user communication. But in service status duty of com2 port is changed and set as service port in Options Menu. All data of UPS can be accessed by this communication way. All the voltage and current values measured by UPS, alarms, warning and status messages can be monitored. Because the communication system is designed in an interactive manner, UPS may get commands from monitoring and control units. These commands are listed below:

 Switch to BYPASS  Switch to INVERTER  SOUND on/off  Adjust UPS time and date  Quick BATTERY TEST  BATTERY TEST until battery low alarm  CANCEL battery test  Turn off UPS output voltage immediately (SHUTDOWN)  Turn off UPS output voltage after delay (WAITING SHUTDOWN)  Turn off UPS output voltage (SHUTDOWN) and turn on UPS output voltage (WAITING

RESTART)

 CANCEL SHUTDOWN  RENAME UPS

These commands are evaluated only if REMOTE CNTRL: ON option is selected in OPTİONS/COMMUNICATION OPTIONS menu and if user password is sent from this (com2) port.

Otherwise UPS doesn’t perform these commands and only information can be obtained from the

ports. Special softwares are required in order to use the serial communication ports. Some of the commands

above have special functions and they can only be activated and used by operating TMON program groups on a PC that is serially connected to UPS.

TMON program group includes softwares developed by VISION. Additionally, remote monitoring and control is provided in every kind of operating systems, by using

worldwide known and continuously devoloping software programs. These softwares can be supplied from VISION.

9.2 Serial Communication Port Connection Cable

The maximum length for RS232 communication cable should be 25 meters. For remote panel and UPS connection the same pin configuration is valid. Connection terminals of RS232 cable is shown below for com1 and com2 ports:

Page 60

PREMIUM DSP 40-80 KVA PF0.9 3/3 - UPS www.visionups.com

9.3 Modem Connection

A DSP0.9 Series UPS can be controlled through a normal telephone line by means of a remote operator connected through a PC with modem device, who performs a phone call to the UPS connected number. So the operator can see all parameters and control the UPS (if permitted from OPTIONS MENU).

9.3.1 Hardware Configuration

All requirements for modem connection are as follows:

 PC with modem  WINDOWS 98  Available UPS control software (T-MON)  NULL modem which is connected to UPS

UPS has its command set to set NULL modem to auto answer mode. In order to do this, press ENTER button for 3 seconds in ENTER: MODEM INIT item in COMMAND MENU after the hardware is installed. A short beep sound warning is heard after pressing the buton. RX and TX lights of the connected modem activates. Modem is set after this to answer external calls by telephone line. To test this, call the telephone number that the modem is connected with another phone and listen the modem sound.

NOTE: Not all the modems are compatible with the command set on UPS. In such a case

modem should be set by connecting a PC.

9.3.2 Functioning Principle

The remote operator, by means of a PC and a modem device and using the remote connection function of the control software, calls the UPS through the number to which this is connected. The NULL modem device, connected to the UPS, will answer the call and convert the data coming from UPS’s serial port on to the telephone line. This way all measurements and controls allowed by the RS232 serial port can be carried out.

9.3.3 Modem Programming Procedure

Smart modem (SM) is the one connected to PC, and NULL Modem (NM) is the one connected to the UPS. Standard Hayes AT programming language is the suitable language for modems. In usual applications a modem which uses AT command set should be selected.

9.3.3.1 Smart Modem (SM) Programming

The connected modem to PC (smart modem) will be programmed from UPS control software (T-Mon) automatically. B0 E1 F1 M1 Q0 V1 X3 BAUD = 2400 PARITY = N WORDLEN = 8 DIAL = TONE (TONE which can be programmed)

ATTENTION: Maximum 42Vac or 60Vac voltage may be applied to the dry contacts of the

interface. Dry contact relay outputs are NO (Normally Open) type, ie. the relay is not activated if alarm is not present and the contacts are open circuit.

9.5 Remote Monitoring Panel Connection of UPS

This panel is used to control and monitor UPS remotely up to 400 m. distance from it. Panel is located in monitoring and control room. If the distance is not longer than 25 m. RS232, if longer RS485 communication protocol is used. RS485 requires additional adapter.

Remote monitoring panel communicates UPS in a serial way and transfers information to user. Remote panel requires 220Vac 50Hz supply voltage and it is recommended to get this supply from UPS output.

Products should be used according to the conditions and procedures defined in the manual. When this is made the most efficient usage of the product is guaranteed.

1. Energy efficiency means, decreasing consumed energy amount to the minimum level possible

in every step of living activities, without a decrease in quality or amount of produced work or product, and keeping this principle permanent.

An efficiency value is said in operation of every energy consuming device. Roughly, efficiency can be defined as the ratio of work or power -we obtain- at the output of a system, to that of -we give- at the input of same system.

Keeping below recommendations during the selection and operation of an electric powered product, provide more useful, economical and long-lasting usage in terms of energy efficiency. Therefore, user profits economically, as well as supporting to create a cleaner environment and protecting our world sources.

2. Every electric powered device is designed appropriate to a defined power level. Device capacity

should be selected according to its load requirement for an efficient operation.

3. Ensure to operate your device in convenient electrical conditions defined in technical

specifications table. It will work more efficiently in those conditions.

4. Check that operating environment is compatible to defined conditions.

5. Check if the place of installation is suitable as per the conditions mentioned in the relevant

section of the manual.

6. By means of the periodically maintenance work, faulty or unefficient components of the device

may be detected before the major failures. This results in more efficient operation and prevention of failures.

7. Usage of recyclable materials is one of a remarkable keys to more efficient energy consumption

in total. Users should dispose the expired recyclable materials (batteries, electronic components etc.) according to local directions and laws.
