APCC Won't Auto Shutdown After APV2 Driver Quits

Kerry Williams
 

Hello,


I have a vbscript that I am developing to shut everything down gracefully in the event of a roof closure due to weather. 


I set APCC to AutoShutdown ( 1 sec) and unchecked the "Check if OK to Exit". In my vbscript I set the APV2 driver's client count to 0 and it exits successfully when the script is run. However APCC just hangs and doesn't auto shutdown. I have to kill it from the task manager.


What am I doing wrong? 


Thanks,

Kerry

Hi Rolando,
I'm interested in your comment on backlash compensation as in the screenshot the OP posted that setting is under focuser control, so I've always assumed that was to do with focuser backlash and not mount backlash or am I wrong? I have the same 100ms for backlash compensation under focuser control, so you got me wondering.
Elsewhere in the AP V2 driver there are settings for 'Set RA backlash' and Set Dec Backlash', which I presume are the mount settings, for which I have both set to 0, so please could you confirm or clarify.
Best regards,

Geof

Hello again,

I noticed one other thing in your setting. If you will be autoguiding, set the backlash Comp to zero. This has nothign to do with your current problem, but could cause problems later on when you are guiding.

I've noticed on both my Mach 1 and 1100 GTO mounts the "Enable Pointing Correction" and "Enable Tracking
Correction" boxes in APCC Pro occasionally turn on by themselves.
Double-clicking the "Tracking=Sidereal" field in the status bar is a short cut to turn on pointing/tracking rate correction. You may have done that by accident.

On the Mach 1 I have an old pointing model listed in APCC that I don't use (have not had a chance to update it)

so I set everything to 0 so when the checkboxes turn on it's not harming anything.

It is always good advice to check the specs. That would be especially true
with non-astronomy equipment.



I hope you don't see my comments as argumentative. My goal is to help folks
learn when to raise the flag without being paranoid.



I also design this stuff, specifically for astronomy, and we know that some
need to run from battery when AC power is unavailable. Astronomy gear has to
be more robust and tolerant than home electronics. The fact that we use the
equipment outdoors where it gets soaking wet, we should celebrate the
bravery of those who make our astronomy toys. I don't think our tech toys at
home would last very long in this environment.



It's a fabulous hobby and certainly brings out the "MacGyver gene" in all of
us!

I design this stuff for a living and am just reporting the facts.



What "12VDC" means is actually way more complicated than most people assume.



12V lead acid batteries are actually 13.8V when fully charged. That isn't
true for any other battery chemistry and it isn't true for linear or
switching 12V voltage regulators.



Whether or not a particular electronic device designed to operate with 12VDC
input can also operate on 13.8VDC is always an open question that should be
investigated before hooking it up to 13.8VDC. The odds are that it will be
fine but that isn't any sort of guarantee. Check with the device
manufacturer first.



I hope this helps.

I think you are making this way more complicated than it really is.



My point is that when you see a reference to "12V" is almost always
referencing voltage of a "12V" battery. And a 12V battery is more than 12V
unless its almost dead.



Take just about any AC-DC power supply you have around the house and measure
the actual voltage. There will be a label that says "12VDC" but if you
measure voltage you are more likely to see 12.9-16.0V.



If you plan to power any of your gear in "portable mode", you will be using
a battery which is going to be more than 12V. So, relax. It will be just
fine.

Since "authentic" Pyramid power supplies all now come from China and without
any safety certifications of any kind, I am not sure who would be bothering
to make counterfeits.



And not all electronics can handle 13.7 volts when officially rated for 12
volts. It all depends on the design of the power supply circuits inside of
the device in question. Vixen's dual-axis stepper motor systems for their
SP/GP mounts would overheat and burn up their 3-pin, 5 volt linear voltage
regulators if powered from 13.7 volts. Internally, the regulator Vixen used
wasn't attached to a heat sink. If they had done so, the system probably
would have been able to handle 13.7 volts.



If an electronic device is using a cheap, 3-pin linear voltage regulator
inside, raising the input voltage will directly correlate to a rise in
generated heat. All linear voltage regulators handle excess voltage by
shedding heat. That's why most-all of them have heat sink mounting tabs on
them.



And just about everyone uses cheap, 3-pin linear voltage regulators inside
of their electronic devices.



The only exception I am currently aware of is the Astro-Physics CP4, which
uses a tiny switching voltage regulator internally to lower the input
voltage down to 5 volts for its electronics. The CP4 has a PTN78000
switching voltage regulator than can take anything from 7 volts up to 36
volts without any problems and without having to deal with excess voltage by
shedding extra watts of heat. The PTN78000 doesn't even have a heat sink
tab.



http://www.ti.com/product/PTN78000W



And yes, most CCD and CMOS cameras I am aware of are using cheap 3-pin
linear voltage regulators inside where higher input voltage means more
generated heat from those regulators.



Pretty-much everyone designs their electronic devices to use their specific
power supply solutions. If you decide to power a device in question in some
way not specifically sanctioned by the manufacturer, you are taking risks
and shouldn't assume anything. The best way to proceed would be to contact
the device manufacturer and ask them about your alternate power plans. And
even then you won't always get an accurate answer. Many astro-manufacturers
hire other, specialist-companies as subcontractors to design their devices
for them.



So anyway there can be a number of excellent reasons why you might not want
to power all of your generally-12-volt devices from a single common 12V or
13.8V power supply.



I hope this helps.

Subject: RE: [ap-gto] Re: 12v power supply.

There are lots of fake Pyramid power supplies out there in internet land. A
clue is price. As with most things, you get what you pay for.



I see quite a bit of banter on this thread. I see some suggesting that 12V
should be the max. for astronomy equipment, but that is not quite correct.
You can't look at just voltage by itself. Almost all astronomy equipment was
designed to run from 12V so you could run it from a big battery. BUT, a
battery that measures only 12V is an almost dead battery. So, 12V almost
never means a measured voltage of 12V. Normal range would be 12.9-13.8V on a
freshly charged battery.



Some confusing info here as well. Someone suggests that running a CCD Camera
at higher than 12V causes excess heat. I'm doubtful about that. In fact, the
camera itself uses almost no power and is normally a 5V buss which means
there is a step-down power supply which just about all electronic devices
use. The cooler on a CCD camera is what needs 12V and quite a lot of it. If
you reduce voltage, current will go up and that is more damaging than
voltage.



There is a common misunderstanding about how electricity does its thing. The
best analogy is water. It takes a combination of pressure (voltage) and flow
(current) to do useful work. If you reduce the pressure (voltage) you need
to increase flow (current) to compensate. For electricity, current is
expressed in AMPS. Many electronic devices state a specification in "WATTS"
which is a combination of voltage and current. Reducing voltage means
current needs to go UP and that can do more damage to electronics than
higher voltage will. Reducing voltage also means larger gauge wire is needed
to handle the increased current. Lowering the voltage and keeping the same
wire gauge can cause the higher current to create heat in the wire (or
circuit board) itself. There's a reason that those big overhead transmission
wires carry voltage in the 10's of thousand volts. To transmit only 110V the
wire would need to be enormous and voltage at the far end would not be 110V
anymore.



Anyway, there is no reason why a proper, single power supply cannot operate
all of your 12V equipment. The key is, it needs to supply enough current
(amps) and some extra buffer helps. So a good rule of thumb is to add up the
total current (amps) when all your gear is running at the same time, then
double that when choosing how many amps your power supply needs to output.
Things that produce heat (or cooling) using electricity needs quite a lot,
so dew heaters and CCD coolers are going to be your biggest consumer. The
mount doesn't use much except during a high-speed slew. When looking at
heaters, don't be fooled by "energy efficiency". A low watt heater can't get
the job done when the dew/frost is especially bad. More amps/watts = more
heat when you need it.

Hawaii for Christopher to examine and he said it was working OK, but quite
warm. He said he wouldn't draw any more than 4 amps from it, even though
it's rated at 10 amps. My older one (exact same model) was working fine
when I lost confidence in the brand and replaced it with a Powerwerx

"We sell them. We use them also."



I assume you mean the Pyramid power supply. When I bought my Mach1 in early
2010, I also bought the Pyramid PS-9KX from Astro-Physics. I assumed that
if A-P sold it, then it was probably dependable, and so it has proven to be
during the almost 8 years I've had it. I have no complaints. A few years
ago I read comments on CN that somebody had tested some of these, and they
were putting out less than the claimed 12.8VDC. I tested mine a few minutes
ago, and it's putting out 13.9 VDC, which I figure is close enough. One
change I made is with the power cord for the mount. A dog chewed up the
cigarette-lighter plug, so ! I took the opportunity to strip the wires and
install spade lugs to use the screw terminals on the Pyramid. I duly note
the comment about a Pyramid suddenly spiking to 22 volts. I'll stay alert
for any anomalies.

Personally, I would never connect a Pyramid power supply to a very expensive mount of this caliber.  Stick to the Powerwerx, Alinco or at least of this class.  Save the Pyramid for your dew heaters.
