1
00:00:00.565 --> 00:00:02.181
Ground Truth, for operators.

2
00:00:02.181 --> 00:00:04.228
Unloading a truck, step by step.

3
00:00:04.651 --> 00:00:07.026
This is the door of panel CP-101.

4
00:00:07.026 --> 00:00:11.685
Between trucks, the receiver sits nearly
empty, and the pumps are locked out.

5
00:00:13.281 --> 00:00:13.817
Step one:

6
00:00:13.817 --> 00:00:18.484
the driver connects the hose, and
acid drains into the receiver, V110.

7
00:00:20.031 --> 00:00:20.617
Step two:

8
00:00:20.617 --> 00:00:22.506
press reset, HS-V110D.

9
00:00:22.506 --> 00:00:26.088
The placard says to reset
only at the end of unloading,

10
00:00:26.088 --> 00:00:30.326
but this logic needs a reset at
the start of every truck, too.

11
00:00:30.869 --> 00:00:34.988
When the level passes low, the green
lamp lights, and both pumps may run.

12
00:00:36.678 --> 00:00:37.329
Step three:

13
00:00:37.329 --> 00:00:42.086
start pump P111A at its local
station, and let the trailer empty.

14
00:00:47.169 --> 00:00:48.865
At low-low, the truck is empty.

15
00:00:48.865 --> 00:00:51.871
The pump stops, and the
controller calls for the horn.

16
00:00:51.921 --> 00:00:53.043
You will not hear it.

17
00:00:53.043 --> 00:00:55.059
Its fuse carriers were found open.

18
00:00:56.970 --> 00:00:57.535
Step four:

19
00:00:57.535 --> 00:00:59.175
press reset again to silence.

20
00:00:59.175 --> 00:01:02.032
The pumps stay locked
out until the next truck.

21
00:01:03.638 --> 00:01:04.346
Step five:

22
00:01:04.346 --> 00:01:06.256
tap purge, HS-V110B.

23
00:01:06.256 --> 00:01:09.523
The amber lamp shows the sixty-second purge.

24
00:01:09.573 --> 00:01:12.964
The selector beside it holds
a purge on with no time limit.

25
00:01:12.964 --> 00:01:15.032
And never purge with a pump running:

26
00:01:15.032 --> 00:01:17.014
only the door legend stops you.

27
00:01:18.028 --> 00:01:21.608
On high-high, the proposed
response is to stop the transfer,

28
00:01:21.608 --> 00:01:26.104
check the level locally, and reset
only once it is back below high-high.

29
00:01:27.023 --> 00:01:30.375
Two resets every truck, and
never purge with a pump running.
