EMERGENCY AUTOSPILL
PLC INPUTS
1. PULL RELAY'S FROM BOP PLC DROP 1 TO OLD AUTOSPILL PLC
2. USE A SEPARATE ANALOG INPUT ON DROP 9 FOR HH HEADWATER
3. REMOVE HH HEADWATER POINT AND INSERT NEW TEST POINT FROM
ANALOG INPUT
4. MOVE PROCESS CALIBRATOR TO SIMULATE HH HEADWATER ANALOG
POINT
5. VERIFY SPILLGATE MOVES TO 3.3 FT, 5600 CFS
6. MOVE PROCESS CALIBRATOR TO SIMULATE AN EXTREME HIGH
HEADWATER ANALOG POINT
7. VERIFY SPILLGATE MOVES AN ADDITIONAL— 2 FT, 3000 CFS
8. TOTAL 5.2 FT, 8500 CFS
9. TEST 1 SETUP — UNIT TRIP WITH HH HEADWATER
a. MS RELAY HIGH
b. 94G RELAY LOW
c. UNIT TRIP RELAY LOW
d. UNIT CFS 12mA, 5075 CFS
10.TEST 1
a. UNIT TRIP RELAY FROM LOW TO HIGH
b. MS RELAY FROM HIGH TO LOW
c. VERIFY CFS MOVE — 5075 + 8500 CFS = 13594 CFS
d. VERIFY GATE MOVE — 8.2 FT
11.MOVE PROCESS CALIBRATOR TO PROPER HEADWATER LEVEL
12.MOVE GATE TO 0 POSITION
13.SWITCH ANALOG POINTS FROM HEADWATER TO TAILWATER
14.MOVE PROCESS CALIBRATOR TO SIMULATE LL TAILWATER ANALOG POINT
15.VERIFY SPILLGATE MOVES TO 3.3 FT, 5600 CFS
16.TEST 2 SETUP — UNIT TRIP WITH LL TAILWATER
a. MS RELAY HIGH

b. 94G RELAY LOW
c. UNIT TRIP RELAY LOW
d. UNIT CFS 12 mA, 5075 CFS
17.TEST 2
a. UNIT TRIP RELAY FROM LOW TO HIGH
b. MS RELAY FROM HIGH TO LOW
c. VERIFY CFS MOVE — 5075 + 5600 = 10675 CFS
d. VERIFY GATE MOVE — 3.5 + 3.5 = 7 FT
18.MOVE PROCESS CALIBRATOR TO SIMULATE NORMAL TAILWATER
19.TURN LL TAILWATER BYPASS SWITCH TO BYPASS LL TAILWATER
20.MOVE PROCESS CALIBRATOR TO SIMULATE LL TAILWATER ANALOG POINT
21.VERIFY SWITCH DISABLES LL TAILWATER PLC SPILL
22.MOVE PROCESS CAIBRATOR TO SIMULATE NORMAL TAILWATER LEVEL
23.REMOVE TEST EQUIPMENT
24.LEAVE AUTOSPILL RELAY'S ON BOP DROP 1 DISABLED
EMERGENCY AUTOSPILL
HARD WIRED RELAY'S
1. 1/0 CHECKOUT FOR EMERGENCY AUTOSPILL HARD WIRED RELAY'S
2. MEASURE RESISTANCE ON THE EMERGENCY AUTOSPILL CIRCUIT
3. CLOSE BREAKER
4. SET GATE RAISE TIMER TO 2 MINUTES
5. SET DRIVE TIMER TO 2 MINUTES —VERIFY TIMER MODE AND TIME
6. SET SIREN TIMER FOR 1 MINUTE
7. JUMP HH HEADWATER SWITCH
8. VERIFY GATE RAISES FOR 2 MINUTES
9. VERIFY DRIVE TIMER TIMES FOR 2 MINUTES
10.VERIFY GATE RAISES FOR ANOTHER 2 MINUTES
11.REMOVE JUMPER
12.PLACE SPILLGATE 1 IN AUTO AND LOWER GATE TO 0 POSITION
13.PLACE SPILLGATE 1 IN OFF TO SIMULATE A PLC FAILURE
14.PLACE JUMPER ON LL TAILWATER SWITCH

15.VERIFY SIREN TIMES FOR 1 MINUTE
16.VERIFY GATE RAISES FOR 2 MINUTES
17.VERIFY DRIVE TIMER TIMES FOR 2 MINUTES
18.VERIFY GATE RAISES FOR ANOTHER 2 MINUTES
19.REMOVE JUMPER
20.VERIFY TIMER LOGIC STOPS TIMING
21.PLACE EMERGENCY SPILL DISABLE SWITCH TO DISABLE
22.INSTALLJUMPER ON LL TAILWATER SWITCH
23.VERIFY LL TAILWATER EMERGENCY SPILL DOES NOT OPERATE
24.REMOVE JUMPER
25.RESTORE EMERGENCY SPILL SWITCH TO NORMAL
26.PLACE SPILLGATE 1 IN AUTO AND LOWER GATE TO 0 POSITION
27.CHANGE DRIVE TIMER TO 45 MINUTES
28.VERIFY GATE TIMER IS AT 2 MINUTES
29.VERIFY SIREN TIMER IS AT 1 MINUTE
30.PLACE SPILLGATE SELECTOR SWITCH TO SPILLGATE 2
31.JUMP LL TAILWATER TO VERIFY SPILLGATE 2 RELAY ENERGIZES AND DOES
NOT MOVE SPILLGATE 1
32.PLACE SPILLGATE SELECTOR SWITCH TO SPILLGATE 3
33.JUMP LL TAILWATER TO VERIFY SPILLGATE 3 RELAY ENERGIZES AND DOES
NOT MOVE SPILLGATE 1
34.PLACE SPILLGATE SELECTOR SWITCH TO SPILLGATE 1
