Notes
- The following is from Jana answering some of my questions:
-No Format - What
- does
- "current
- delta
- is
- in
- range"
- mean?
Current
delta
is
defined
as
the
difference
between
a
BPU
current
measured
before
a
unit
is
turned
on
and
after
a
unit
is
turned
on.
Forexample,
before
the
SIU
is
turned
on,
the
BPU
SIU
feed
will
register
0.1A
(don't
ask
why
it's
not
zero).
After
the
SIU
is
turned
on,
it
will
read
0.7A.
The
current
delta
for
turning
the
SIU
on
is
0.6A.
You
can
do
the
same
for
the
DAQ
feed
for
the
PDU
and
-GASU.
- How
- to
- issue
- LMAINFEEDON
- command?
You
- should
- be
- able
- to
- issue
- the
- LMAINFEEDON
- command
- more
- than
- once
- (can
- you?)
- and
- you
- should
- be
- able
- to
- turn
- on
- primary
- GASU
- first
- followed
- by
- PDU0.
- These
- will
- be
- separate
- calls
- to
- LMAINFEEDON
- and
- you
- should
- read
- the
- BPU
- current
- on
- the
- DAQ
- feed
- before
- and
- after
- you
- turn
- each
- on
- and
- see
- that
- the
- difference
- is
- appropriate.
Yes,
- PDU
- on
- is
- a
- separate
- command
- (to
- LMAINFEEDON)
GASU
- on
- is
- also
- a
- separate
-- command.
- Don't
- worry
- about
- LTC_init
- for
- now.
- LTC
- is
- undergoing
- some
- changes,
- so
- it
- doesn't
- pay
- to
- worry
- about
-- it.
- What
- are
- the
- CAL
- and
- TKR
- bias
- voltages
- supposed
- to
- be
- set
- to
- upon
- power
- up?
- Should
- they
- be
- the
- same
- as
- the
- current
- values
- in
- the
- clean
- room?
- What
- is
- their
- nominal
- value?
Looks
- like
- Rich
- gave
- you
- an
- answer
- to
-- that.
- Testbed
- doesn't
- model
- CAL
- Baseplate
- temperatures.
- Why
-- not?
- Testbed
- doesn't
- seem
- return
- valid
- values
- for
- TKR
- T1
I'm
- hoping
- you
- have
- an
- answer
- from
- Owen
- on
-- these?
- Does
- the
- ACDPowerOn
- Command
- enable
- the
- converters
- inside
- the
- GASU?
Yes,
- it
- should.
If
- so,
- why
- is
- there
- a
- separate
- step
- for
- enabling
- the
- converters?
That's
- Rich's
- mistake.
- Just
- use
-- ADCPowerOn.
- What
- is
- the
- nominal
- value
- for
- the
- bias
- voltage
- for
- the
- ACD?
clue - What are the proper ranges for all of these values? Systems will provide, but they haven't yet.
No
- clue
- What are the proper ranges for all of these values?
Systems will provide, but they haven't yet.
