Name of the Company: APC

Designation: Test Engineer

C.E.1 : This project covers the period October, 2011 to Dececember,2011. I handled this project at American Power Conversion (APC) (where I am working)-A Schneider Electric Company (I) Pvt.Ltd,IDF5,#187/3¼/3 Jigani,Bangalore-562106,Karnataka,India.

My designation during this project was Test Engineer.

The project was – ” Charger Current Too low Failure in Tomcat model”

C.E.1.1 : The nature of the engineering project was to ensure that the failure target of TOMCAT ( UPS System) was kept at 11% as against the existing failure rate of 40%. The features of the TOMCAT ups system are:

15-20kVA, Double conversion UPS
UPS can be configured as 3:3, 3:1 or 1:1 for single feed or dual feed.
In Bypass Mode, Inverter can work as PFC to keep charger and logic power supply functional incase PFC is unable to operate
Unit can be turned-on without batteries.
Smart Battery Management, through CAN communication between UPS and Battery Packs

C.E.1.2: The objective of the project was to ensure and keep the failure target of TOMCAT at 11% as against an existing failure rate of 40%. The other objective was to bring out much efficient performance of the product through minimizing the TOMCAT failure.

C.E.1.3: The nature of my particular work area was to closely monitor all the failures in the PCB level testing and provide corrective action. As a team member of DPU reduction team, I collected all failure rates related to this product in PCB functional test.

C.E.1.4: ORGANIZATION CHART

C.E.1.5: My duties and responsibilities are as follows:

C.E.1.5A: As a member of test engineering team, I am responsible to take care of test relates equipment like In Circuit Testers (i.e Teradyne ICT machines), PCB Functional test jigs and test fixtures for UPS Testing.

C.E.1.5B: Responsible to ensure safety measures in work place and supporting to health and safety department to implement safety feature in testing area. Identifying risks and giving mitigation for identified risks.

C.E.1.5C: Schedule meeting in weekly basis with my team to discuss OEE (Overall Equipment efficiency), and FTY (First through Yield) and plan tasks for forthcoming week.

Educational Qualification

C.E.1.5D: Responsible to Implement test specifications in ATE using Lab View / C, C++ software.

C.E.1.5E: Constructs prototype of new test equipment and work with construction test team to debug of high volume production test hardware and software.

C.E.1.6: PERSONAL WORKPLACE ACTIVITY

C.E.1.6A: How you applied your engineering knowledge & skills:

In my POST Diploma in Power Electronics ( NTTF Training Center,)second semester I have learned Microcontroller 8086.This helped me to understand the functionally and the response of the programming IC
In my POST Diploma in Power Electronics ( NTTF Training Center,)second semester I have learned PIC microcontroller .This helps me to understand the functionality of the RTC µC
In My B.Sc. Electronics which I have completed from Bharatiyar University I have Learned Microcontroller 8085 which helps me in understanding the functionality of RTC µC

The test process that was followed was to do the ICT test then programming and then send the board for conformal coating. After doing the conformal coating the boards will be send to the final build line for assembling to ups. The assembled ups will be undergoing final test if the RTC board is not programmed it will fail in the start up. We were not doing any verification for the board whether it is programmed correctly and there is no Quasar entry for this board (Quasar is database for checking the pass or fail of board with the board serial number). Operator in a tracking sheet tracked this where some time the operator fails to update and it was human depended. As per the procedure is concern, there is a switch that the operator needs to select in the RTC board for doing programming. Sometimes if the operator forgets to select the switch in the right-position and it will program wrongly.

To overcome this failure I have made an automated test setup to perform the programming verification before sending to the conformal coating. I have designed a BON (bed of nails) which can be interfaced with Functional tester. The bon consist of a controller unit which is used in the UPS .In the ups the Rtc board will be connected to a main controller. As per the main controller instruction, it is performing the function. My idea is to simulate the same this by powering up the controller .The controller will be interfaced with a computer that is loaded lab view program. The communication with the controller and the computer will be mode bus communication. Through mode bus communication, the computer is checking the hex data present in the address lines whether it is programmed or not.

For the following test steps of functional test it is necessary to put the RTC1 PCBA under full operation, this means that serial communication with Application PCBA µC via CMX1 PCBA has to be established to read out values of RTC1 PCBA and to check all functionality of PVO1 µC.

Professional Experiences

For that reason, it is necessary to connect the RTC1 PCBA via S400 connector and via a CMX1 PCBA to an AIC electronic control block (application – , display – , terminal – , HHP_I1 – and HHP_MC1 – PCBA). In addition, test equipment (e.g. a LABVIEW tester) with modbus communication function (or PC with “MBU-PARAM” software tool) has to be connected to the electronic control block to exchange data with RTC1 µC via application PCBA software interface.

Application PCBA:

1 (XCAPP_iX1.1IE06#1.mot)

HHP_MC1 PCBA:

(XCLC1_iX1.1IE02#9.run)

RTC1: (device under test): (XCRTC1_X1.1IE02#1.hex)

This step is only necessary, to check at beginning whether the content of the EEPROM and software version of AIC controlblock (parts of fixture) are O.K.

First power up to build up the configuration for modbus communication

-Apply +24V ±0,2V DC at HHP_I1 PCBA from P24M1 (X4-2,4,9) to 0VM (X4-1,3,8)

-Apply +5V ±0,1V DC at HHP_MC1 PCBA from P5F (X1-18,24,38) to 0VF (X1-20,32,36)

-Apply +15V ±0,1V DC at HHP_MC1 PCBA from P7F (X1-12) to 0VF (X1-20,32,36)

Next is modbus diaog setup by start the labview modbus communication tool. modbus address “248” since this value is always accepted.

-Read object MODE until this object become “OK”; timeout = 1min

-Write 0x0002 to object PARA to enable parameter access via modbus

– Write 0x23FF to object SVCD to enable RTC1 test parameters
