IA

Question 1

system pressure order
1
component/position, cycle pressure, PS, Cooled by, temp trip, time unloaded

Answer 1

100-115# = IA-P-4 Cycles

power supply = 1J 480V BUS

cooled by SCCW

428°F = Trip

20 minutes unloaded = Auto Shutdown

Question 2

2
component/position, cycle pressure, cycle off what? PS, cooled by? swap to what/when? temp trip, time unloaded/action

Answer 2

100-110# = IA-P-1A/B Cycle IF IN HAND (lead)

power supply = 1A/B ES MCC

cycle off receiver pressure

cooled by SCCW, swap to FS on all 3 SC pump breakers open

425°F = Trip

5 minutes unloaded = Auto Shutdown

Question 3

3
component/position, cycle pressure, cycle off what? PS, cooled by? swap to what/when? temp trip, time unloaded

Answer 3

95-105# = IA-P-1A/B Cycle IF IN Auto (normal)

power supply = 1A/B ES MCC

cycle off receiver pressure

cooled by SCCW, swap to FS on all 3 SC pump breakers open

425°F = Trip

5 minutes unloaded = Auto Shutdown

Question 4

4
component/position, cycle pressure, cycle off what? PS, Cooled by?, temp trip, time unlaoded, normally in what?

Answer 4

90-100# = SA-P-1A Cycles

power supply = 1C 480V TP MCC

cycle off receiver pressure

cooled by SCCW

425°F = Trip

5 minutes unloaded = Auto Shutdown

Normally in Auto

Question 5

5
component/position, cycle pressure, cycle off what? PS, cooled by what? temp trip? time unloaded, normally in what?

Answer 5

85-95# = SA-P-1B Cycles

power supply = 1D 480V TP MCC

cycle off receiver pressure

cooled by SCCW

425°F = Trip

5 minutes unloaded = Auto Shutdown

Normally in Auto

Question 6

6
component/position, cycle pressure, cycle off what? PS? normally in what?

Answer 6

85-115# = IA-P-2A/B Cycles

power supplies = 1A/B ES MCC

cycle off receiver pressure

Normally in Auto

Question 7

7
pressure, alarm

Answer 7

85# = IA low pressure alarm for Primary or Secondary Plant

Question 8

8
component/position
pressure
PS

Answer 8

85# = IA-V-2104A/B open

power supply = 1Q DC

Question 9

9
pressure
component/position
how does it reset?

Answer 9

80# = IA-V-1 opens

Auto Reset

Question 10

10
pressure
alarm

Answer 10

75# = SA low pressure alarm

Question 11

11
pressure
component/position
closed how and from where?

Answer 11

75# = IA-V-2133 opens

manually closed from CR

Question 12

12
pressure
component/position (swap)
component/position (2 valves open/feed), 4 CO, 6 FW, 6 MS

Answer 12

70# = IA-P-2A/B switching valves swap

IA-V-1542/1533 open and feed

CO-V-5/7/8/51

FW-V-7A/B, 16A/B, 17A/B

MS-V-3A-F

Question 13

13
pressure
manual action

Answer 13

60# = Trip Reactor (manual)

Question 14

14
component/position
answer auto opens(resets)
PS

Answer 14

60# = IA-V-26 closes

auto opens (resets)

power supply = 1Q DC

Question 15

15
pressure
component/position to do what
4 MS valves, 4 EF, 1 RR

Answer 15

60# = IA-V-1626A/B open to supply 2 HR Air to:

MS-V-4A/B, 6 & PC-5

EF-V-30A-D

RR-V-6

Question 16

16
pressure
component/position action
all 2 HOUR air valves do what?

Answer 16

60# BANK PRESSURE = IA-V-1625A/B open and vent banks to atmosphere

all 2HR air valves FAIL SAFE
