NOTES TO THE MATRIX
(1) MEDIAN.
(2) MEAN.
(3) MAX.
(4) 1oo2 VOTING LOGIC.
(5) 1oo3 VOTING LOGIC.
(6) 2oo3 VOTING LOGIC.
(7) 3oo4 VOTING LOGIC.
(8) ALARM FOR FUEL GAS PIPING PRESSURIZED WITH UNIT STOPPED, ENABLED 180 sec. AFTER LINE DEPRESSURIZATION COMMAND.
(9) ACTIVATED DURING FUEL GAS START-UP SEQUENCE. LOSS OF ZSL SIGNAL DURING NORMAL OPERATION CAUSES ALARM FOR 20VG-1 VALVE FAILURE OPENING.
(10) VALVE CLOSE LIMIT SWITCH STATUS: ACTIVATED (VALVE TOTALLY CLOSED) DURING STARTING SEQUENCE -> ALARM AND INHIBIT TO START. DEACTIVATED (VALVE NOT TOTALLY CLOSED) AT THE END OF STARTING SEQUENCE -> ALARM
(11) TRIP IF 1oo4 SEISMIC ELEMENTS IS ABOVE “HH” LEVEL AND AT LEAST ONE OF ALL THE OTHER THREE SEISMIC ELEMENTS IS ON ALARM LEVEL “H”.
(12) TSHH ARE INCLUDED IN HEATERS. HH MEANS HEATER CUT-OUT, NOT GAS TURBINE STOP.
(13) HIGH PRESSURE ON BALANCING LINE DISCHARGE SIDE COMPARED WITH COMPRESSOR SUCTION PRESSURE.
(14) FOLLOWING CONTROLS ARE CREATED BY UNIT CONTROL PANEL MARK VIe PCD:


-l3 = R = 1.44
-l2 = R = 1.35
-l1 = R = 1.05
-l4 = R = 1.2 cut-out liquid fuel.

WHERE “R” IS: (PT 208 + PT 212) / ((PT205A + PT212) x 0.975)

OR FOR NP INTERNAL USE (96AA + 96AP) / ((96CD +96AP) x 0.975)


(15) WHEN SELECTED AS AUXILIARY
(16) 1oo3 VOTING LOGIC. LEL = 5%
(17) 2oo3 VOTING LOGIC. LEL = 10%
(18) FOR TRAIN C-231-001B, TAG OF XV, XX AND RELEVANT LIMIT SWITCHES ZSH/ZSL SHALL BE 2128
(19) FOR TRAIN C-231-001B, TAG OF XV, XX AND RELEVANT LIMIT SWITCHES ZSH/ZSL SHALL BE 2122
(20) TAG FOR TRAIN “B” SHALL BE 2125
(21) VALVE CLOSE LIMIT SWITCH STATUS:
IF ACTIVATED (VALVE TOTALLY CLOSED) DURING STARTING SEQUENCE -> ALARM & INHIBIT TO START
IF DEACTIVATED (VALVE NOT TOTALLY CLOSED) ABOVE MINIMUM OPERATIVE SPEED OF G.T. AXIAL COMPRESSOR -> ALARM
(22) SHUTDOWN IF ALREADY SWITCHED
(23) “A” STANDS FOR “AUTO”
“I” STAND FOR “INHIBITED”
(24) The logic that would be followed to perform the ON / OFF command for the heaters and the logic that must be considered during GT starting is:

Logic to be managed by DCS and MCC:
IF FE-5005A (unit 1) + FE-5005A (unit 2) > or = 3000 kg/h AND IF TIT5041 (96FTG) < + 4°C THEN: heater ON.
IF TIT- 5039 (FTG-1A) or TIT0340 (FTG-1B) > or = + 7°C OR IF TIT- 5041 (96FTG) > + 90°C THEN: heater OFF.
Logic to be managed by MKVIe:
The interlock to the opening of SRV/GCV during GT starting procedure: IF TIT5039 (FTG-1A) or TIT5040 (FTG-1B) > or = + 8°C AND TG-FG-1 (231-TE-5006AA) is not low


"START PERMISSIVE" MEANS PERMISSIVE TO INITIATE THE STARTING SEQUENCE
"RUN PERMISSIVE" MEANS PERMISSIVE TO INITIATE THE TURBINE STARTUP
