4. PRELIMINARY CHECKS

4.1 CONFORMITY WITH THE SPECIFICATION :

The installation and the connection of the equipment should be checkedbefore all action.

4.2 INSTALLATION CHECK

Installation general aspect

Equipment aspect (no spot, stripe, wrapping, oxidation, edgesmoothing).

Painting aspect

Minimum clearance between side and walls: 1 m

4.3 CABINET CHECK

1. Check wiring, whether any of the connectors are loose intransportation. Check especially the presence and cross-section of:

a. The link between 0V bus bar and earth.b. The link between cabinet earth and site earth network.

2 Check fixing of cabinet.3 In case of false floor, cabinets should be fixed on metallic support

by 4 points. In case of concrete floor; cabinet is fixed directly on theground by 4 points.

4 Check for easy opening of doors.

5. EARTHING GUIDELINES

1. Two numbers of Earth studs are provided on the topside ofthe power plant with crimping lugs.

2. Crimp the lugs with proper tools.3. Connect the Earth cable to power plant on any or both Earth

terminations.4. Use at least 10 Sq. mm. Wires for the termination of earth to

the power plant.5. Measure the Earth resistance; it should be less than 0.5

Ohms.6. Proper earth is required to communicate with the remote site

through RS-485.7. Connect earth to the foundation bolts.8. Separate earth should be used for +Ve grounding.9. Timely watering the earth pit is essential so that its

resistance will be within limit.10. Use only Copper/Lead Plates and bus bars for earth

continuity.11. Use at least four earth pits and short it with bus bar to

achieve good results.12. Improper earth to the power plant may cause failure to the

power plant due to lightning.

6. ENERGIESING OF THE POWER PLANT

1 All disconnecting devices should be in the {{open}} position. Check thatthe mains voltage and frequency is as indicated in the name plate.

2 Do not install the modules before the mains and battery wirings arecompleted.

3 For easy accessibility, remove the modules before operate the batteryfuses or disconnecting switches.

4 Switch ON AC I/P MCB & DC O/P MCB off all the modules.5 A healthy module will indicate DC voltage and current on DSCA by

pressing UP key on front panel LCD.6 Close all fuse disconnecting switches and load protecting circuits of thepower stations.

7 Check for proper operation of the system according to technical datasheets.

7. COMMISSIONNING TESTS

7.1 Check the measurements on System Display AC Voltage Load Voltage Load Current Battery 1 Current Battery 2 Current Battery 3 Current System Current Battery Status

7.2 OPERATING CHECKS Float Voltage 54.0V 1% at 27C Charge Voltage 55.2V 1% at 27C Switch OFF mains, the system will change over from mains I/P to battery,

which will generate alarm of Mains Low with audible alarm. The power cut off or pre alarm when the battery voltage reaches the

setting threshold Load volt low and Bat disconnect alarm displayed.To achieve this test, replace the battery by the DC power supply anddisconnect all the rectifiers.

Check FR/FC XX NOT PRE alarm by switching off the I/P O/P MCB ofrectified module.

Decrease system Float voltage till 44.0 V. Rectifier under voltage operatesand on FR/FC as an alarm red LED DC Fail / DC UV glows. The samealarm is extended to DSA as FR/FC XX FAIL .

Check Battery X absent by Dialing the non-zero AH capacity in menuwithout connecting batteries to the system.

Check Batt X Isolated by Dialing the 000 AH capacity in menu when allthe batteries are connected to the system.

Check ONLY ONE BATT!! by manually isolating the batteries one byone. This alarm appears when only one battery is connected and userwants to isolate it.

Check Temp X comp fail alarm by shorting or disconnecting the

external battery temperature-sensing device.

10. SYSTEM STATUS AND ALARM INDICATIONSThe upper portion of the LCD always keeps on scrolling system voltages andcurrents i.e. MAINS VOLT XXX , SYSTEM VOLT XX.X , SYSTEM CURRXXX , BATT 1 CURR XXX , BATT 2 CURR XXX , BATT 3 CURR XXX , andLOAD CURR XXX (XXX is the actual value).In normal working condition, scrolling of parameters may be stopped to observecontinuously any one parameter by pressing ENTER key. When scrolling isstopped, there is * sign after the parameter.

Again to put into scrolling mode press, ENTER key. Scrolling will start and *sign will disappear.The status and any alarm occurred in system is displayed on the lower portion ofthe LCD. If there is any fault occurred in the system then it will go on scrolling the

5. Due to any reason, if module is failed and on module, there is an alarm ofFR/FC FAIL then there is an alarm of FR/FC XX FAIL on system (XXstands for number of module).

6. Due to any reason, if module is not communicating with system orswitching OFF any module, creates an alarm of FR/FC XX NOT PRE(XX stands for number of module). If the module is identified then it willshow the respective number or it will show FR/FC ?? NOT PRE. If themodule number is unknown, check number of FR/FC entered in menu.

9. When Mains AC voltage is less than the Mains low cut OFF voltage set inthe menu then there is an alarm of MAINS LOW. During the alarm the

mains supply of the modules are isolated due to which modules are inOFF condition. When Mains AC voltage restores back with in the specifiedlimit (Hysterisis of 10V is given operate and release levels) there is a delayof 10sec (approx) to turn ON the modules.

10. If some how the system voltage increases beyond the LOAD VOLT HIvalue then there is an alarm of LOAD VOLT HIGH. This alarm is PRE

WARN alarm for battery disconnection.

11. If Mains AC voltage is out of specified limit then the system works onbattery and battery starts discharging. When the battery voltage reachesbelow the LOAD VOLT LOW value set in the menu then there is an alarm

of LOAD VOLT LOW. This alarm is PRE WARN indication beforebattery disconnection voltage.

12. When battery is discharged below LOAD VOLT LOW condition and whenthe battery voltage reaches below the BAT DISCONNECT V value set inthe menu then there is an alarm of BATT DISCONNECT. This alarmdisconnects all the batteries (through DC contactors) connected to thesystem. Now battery will reconnect only when the system voltage rises

above the BAT RECONNECT V set in Menu.

13. The system is having facility to monitor Battery room temperature. Thesystem corrects the DC voltage in 72mV per degree centigrade law. At

27 C there is no correction but as temperature increases system voltagedecreases and wise versa. 55.8V is the lock where further decrease intemperature will not cause any correction. Menu contains Settable rangefor lock in lower side where there is decrease in temperature. When thesensor is short or is open then there is an alarm of TEMP. X COMP.FAIL (X stands for battery number i.e. 1 or 2 or 3).

NOTE: The system has provision to monitor temperature of each batterywith separate probes. When any of the sensors is open or short creates, anAlarm. Among all three temperatures, correction in system voltage is madeaccording to highest temperature.

14. When programming 000AH isolates battery then the respective batterygets isolated and an alarm of BATT X ISOLATED (X stands for batterynumber i.e. 1 or 2 or 3) generated.
