I.INTRODUCTION
The Factory Acceptance Test (FAT) is provided in accordance with the . There
will be a Pre FAT where ** will check all the items are in order and record the
same. After finding everything in order during Pre FAT ** shall give FAT call
with signed Pre FAT document.
GENERAL:
1. The Factory Acceptance Test is carried out in order to demonstrate that
the system and its components function properly, that manufacturing,
assembly, configuration and software generation are done correctly
and that system performance is in compliance with the approved
functional specifications and relevant documents.
2. Daily progress meeting will be held to check progress problems etc.
3. The documentation for F.A.T. will consist of relevant functional
specifications and other approved documents.
F.A.T. SCHEDULE
The Electrical Engineer is responsible for the overall execution of the F.A.T.
and will be the prime interface between the client inspectors and
------------------------- Engineers from the beginning to the completion of the
F.A.T.

PLC START-UP AND POWER FAIL RESTART
OUTLINE
PLC goes to its operating environment on powering up,
provided that all interlocks are satisfied.
OBJECTIV
E
The purpose of this test is to ensure that PLC
automatically boots up when going from 'Power Off'
environment to "Operating environment".
PROCEDU
RE
1. Power off PLC individually or the system as a
whole.
2. Power on each component individually
Each component boots up automatically.
CRIETERIA
In case of Power failure of PLC all the outputs should
FOR
drop and the outputs continue with their earlier state
COMPLIA
after Power restoration; provided all interlocks are
NCE
satisfied.

COMMUNICATION
OUTLINE
PLC is configured for Ethernet communication with CTech SCADA.
OBJECTIV
E
To check whether Ethernet communication is
functioning normally, when SCADA is connected with
PLC.
PROCEDU
RE
On disconection of Ethernet, the SCADA prompts
communication failure message and on connection
SCADA starts functioning normaly.
CRIETERIA
Failure of one ControlNet channel should not affect the
PLC/Plant Operation
