1. SCOPE
This document provides information on nature and details of work involved in “Fabrication,
Testing and Realization of Power Control Unit.
1.1 INTRODUCTION
Power Control Unit, in short called as PCU, is an embedded design using multiple
microcontrollers, housed in a 2U sub rack and is powered from AC 230 Volts source.
The main features of PCU are as follows:
Provides remote interface on RS-485 for automated operations
Controls and monitors Power Simulator output relays
Provides control signals and monitors their status
Provides measurement and monitoring of analogue and digital signals
Acquires Pulse signals and processes to calculate pulse parameters
Data related to critical power parameters are continuously transferred on to a dedicated serial
port (RS-485)
PCU can be operated in LOCAL mode or REMOTE mode. In REMOTE mode, External
Controller controls the unit. Front panel key board and display are used to facilitate Local
mode of operation.
PCU will be put into Local LOCK mode automatically if there is no key depression for a
minute. To Unlock Up and Right Keys are to be pressed simultaneously.
PCU front panel displays important analog & digital parameters
The specifications, hardware details, testing and realisation of PCU are covered in detail in the
subsequent chapters.

4.3 REALY BOARD
DOWNLOADING TO DS89C430: To download the test routines to the main board
controller DS89C430 use the Dallas semiconductor’s MTK2 tool kit. Use an adapter (PCB
99-13-04 VER 1.0) which communicates between the System & the controller. One end of
the adapter is connected to the computer through Female to Female 9 pin DSUB cable where
RX & TX lines are cross connected, the DTR & GND lines are connected to the respective
DTR & GND lines. Other end of the adapter is connected to the on-board connector J1
through a 10 core Flat Ribbon cable.
(Note: While connecting the 10 core Flat Ribbon cable to J1, make sure that pin-1 of the FRC
cable should match with that of the of J1.)
Procedure to download:
1. Switch on the power supply.
2. Open the MKT2 loader and select device DS89C430.
3. Press the push button switch of the adapter board 99-13-04.
4. From the window, select the Target menu and press “open COM PORT at 9600 baud”

Chapter-6
Integrated Unit Level Test Procedures
This chapter discusses in detail the test procedure for the complete integrated Power Control
Unit. Test engineer is required to capture waveforms and note down essential readings as per
the requirement of the test. An exhaustive system level testing of the equipment is to be
carried out, wherein detailed tests, waveforms and readings are to be taken. Necessary ADC
channel calibration for the Main Card is to be done (at the system level during integrated
testing).
The test results should comply with the specifications listed in the table. Unit will be rejected
if test results do not meet the specifications.
6.1 Main Card Related Signals Verification
Control Signals verification: Issue command “#1 SET cmd_no \r” via RS485 control port, where
cmd_no number is indicated in the table as below, and capture 24V Pulse of 150 msec. Repeat this
for all the signals indicated in table.

6.3Thruster Pulse Acquisition verification
- Connect the pin no. J2-26 to J2-41 to 28V supply (all wrt J2-50). Provide the pulse to
the input lines and read the same.- Before reading the thruster pulse parameter send the command "#03 SET 01\r".- Check for the individual thruster by "#03 READ 01\r" and make sure it is reflecting in
the same thruster channel no. Tabulate for different number of pulse simulated using
power supply.- Repeat this for all the 16 channels, and check once for all the channels together.

FABRICATION GUIDELINES
Tools and Equipment: Tools shall be suitable for the purpose intended and shall cause no
damage to the parts, board and solder connections.
Component Tinning & Cleaning: Tinning of the components is mandatory. Clean the
component if required in isopropyl alcohol before mounting on PCB
Soldering: Soldering shall be free from bridging, blow hole, pin hole, crack/dry solder,
excess solder and avoid damage to sensitive components.
Wires / Harness: Sharp bends in wires and harness shall be avoided. Harness shall not have
frictional contact with any mechanical part. Use Teflon grommet of suitable shape and size
whenever a wire or harness passes through a metallic part. Wires shall not be pulled, twisted
or stressed during assembly. Harness bunch shall be free from dirt, chips, loose hardware and
lacing tape scraps etc.
All cards containing COS-MOS devices shall be stored and handled in conductive bags only.
Wiremen/ test personnel shall wear well grounded conductive wrist bands.
PCB: PCBs shall be stored prior to component mounting or after wiring in a controlled
environment, in order to avoid corrosion and oxidation problem, which impairs the
performance of the PCB/wired assembly.
Harness; Harness fabrication and routing as per approved drawing only. Harness shall be
properly fixed to chassis, shall not touch any sharp metal surfaces
Connectors shall be covered with anti-static dust caps
Post fabrication inspection shall be carried-out

ESD CONTOL GUIDELINES
Use static sensitive zone sign to alert the personnel about ESD control
Wear anti-static aprons
Use anti-static wrist strap
Use conductive flooring, don’t use vinyl and wax finished floors.
Use conductive mat in work surface. Avoid synthetic and Formica mats
Chairs shall be conductive, do not use wooden and fiber glass chairs
Store ESD sensitive components and assemblies in conductive (ESD safe) bags. Don’t use
polythene bags
Avoid use of compressed air gun
Avoid equipment like printers, copiers and CRT monitors near ESD sensitive assemblies.
Use of ionized air blowers
Handle ESD sensitive device by holding on body rather than pins
Handle ESD sensitive assemblies by holding on chassis rather than circuitry
Ensure ESD grounding every day
Vendor facility will be audited against above requirements, before placing the purchase
order.
