Re: Mean Well power supply question - closing the loop

Mike C
 

I would have a cover over the top to prevent frost and dew from settling into that open frame. Be warned you are hanging your GTOCP off a lowest price point Chinese made SMPS. Just looking at the PCB design and parts in it is cringeworthy. It is one thing to have a $200 television inside a constant environment house with these cheap switchers but I would never do it to a GTOCP outside in wildly swinging humidity and temps.

Now... this is a -40C certified switcher from TDK Lambda:
Conformally coated circuit boards, Nichicon capacitors, and I know... it's 8x or 10x the cost at $148.

Re: Default.mlm file recovery #APCC

Ray Gralak
 

Hi Claude,

 

APCC automatically saves all settings in compressed files in this folder:

 

C:\ProgramData\Astro-Physics\APCC\Backups

 

Each filename has the date/time in the filename. For example, this settings file indicates the date was 2018, December 10th, 15:34:52 local time (about 3:34 PM):

 

ApccZ-Settings-Backup-2018-12-10-153452.ApccZ

 

From APCC, you can restore any settings file which includes default.mlm from APCC's File menu with the "Load Settings" menu item as shown here:

 

 

BTW, the ApccZ files are just zip container files. If you rename the file extention from “ApccZ” to “Zip” you should be able to open them directly in Windows explorer. However I recommend you use APCC to load the settings so that the files will be placed in the correct folder locations.

Re: Mean Well power supply question

Joe Zeglinski
 

Mike,

Good idea about "isolating " your Mean Well power supply with wood and a plastic enclosure, so you no longer (?) have a leaky ground return to the GFCI, from it.

If the "Euro Safety Regulations", as recently noted by Rolando, require tying power supply DC Returns to chassis/earth ground - dumb idea, unsafe for electronics even with a nearby storm just miles away - and the chassis ground on the 120 AC side of the power supply case and power cord's earth return (third pin) is also tied to house neutral in the fuse box through plumbing or copper ground rod, then why wouldn't the GFCI not trip, when it senses even a few milliamps, (or perhaps just micro amps), supplied by the CPx controller's serial port housing? That's true for many other controllers anywhere on the scope besides just AP's). In such case, the (slightly) leaky chassis ground return is tied to the GFCI circuit protected socket.

The GFCI would naturally trip to protect you from being (potentially) electrocuted by electronics with a chassis ground tied to the pier.
Seems logical. Probably nothing you can do to prevent it, except replace the GFCI outlet for the pier, with a non-fused one. However, your home fuse box panel might also be wired with GFCI breakers. It probably isn't, or you would have a room full of lights drop out every time you power up the telescope electronics, using a normal outlet. GFCI breakers are very sensitive, if they do their job right.

You can likely prove the possibility of the pier chassis leaking current to your GFCI protected AC power cord, supplying your telescope. Using an ohmmeter , check the resistance (continuity) between scope electrical system and GFCI supply - on the unpowered telescope - by touching the probe to the bare serial port screw on the CPx, and the other probe to the earth safety ground pin in the AC socket at the telescope. A meter with a "continuity buzzer" would be easier to use than looking at a reading.

A few milliamps of chassis current won't hurt you, but it is reassuring that the GFCI would protect you from a major short circuit from something at the pier. But, the GFCI can be a nuisance for typically minor amps from pier equipment.

No matter. I have the Mean Well mounted on a board, and enclosed on

Does the Default.mlm file have pre-defined meridian limits? I saved new meridian limits on my installed default.mlm file by accident. If default.mlm has pre-defined limits I'd like to restore them. I moved the overwritten default.mlm file to another directory then re-installed APCC but the new default.mlm file wasn't in it's directory.

Re: Mean Well power supply question

Hi Mike
That's odd. I have never had that problem with mine. I did run mine through a 50' extension cord plugged into a outside outlet in my previous residence. I believe it was a GFCI but I can't say for certain. Did you try the Alinco on another outlet?

I use one a DM-330MV for my ham station, and thought it would be good
for the AP1200 as well.

Sadly, that was not the case.

During the first imaging run with it, I found the mount and cameras dead
-- the GFCI had tripped. I reset the GFCI and tried again. An hour later
it tripped again.

The next night I connected the DM-330MV to a 20W resistor box, and ran
1A of current through it. The GFCI tripped sometime overnight. I tried
that test again the following day -- the GFCI tripped once again.

To be clear: the DM-330V was the ONLY thing being powered through the
GFCI receptacle that tripped.

I don't know why the power supply caused the GFCI to trip. Perhaps it
was the cold temperature or the humidity. The specs state an ambient
temperature of 50F to 95F.

The GFCI problem was the reason I bought the Mean Well supply. Now I
have a spare power supply for my ham station.

Interesting I have that too with Messier objects but since I use APCC I just use TheSkyX to slew to objects. The keypad can slew to stars fine. I updated the keypad to 4.19 a while ago with no issues. My mount is a 1200 built in 2008 so the keypad is the same age.  How would I check the battery status on the keypad?

Re: Mach2 update?

 

Hello Dean,

Most of the parts have been painted and we are busy assembling the Mach2 mechanical parts and electronics. Since this is a brand new mount, our team is taking extra special care to be sure to QC thoroughly and be sure that all the details are taken care of.  Roland is closely supervising the process and will be testing each mount before shipping.

 

At this time we are running a little behind schedule and expect to begin shipping in early December.

WiFi Dropout Solution for Smart Devices (Sky Safari etc.) #WiFi

Howard Hedlund
 

Hi GTO gang!  Some good detective work by some smart people at Lowell Observatory (Thanks Jim C.!) has led us to a probable solution to WiFi dropouts when using Sky Safari, Luminos etc.

It appears we have been looking at this the wrong way.  We were blaming weak or corrupted signal from our WiFi module, and couldn't reproduce the problem here.  Instead, it appears that our signal may actually be too strong and may be overwhelming the smart devices' WiFi hardware. 

For right now, if you are having WiFi dropout issues, please fold your antenna into its little cubby on the GTOCP4, and then try not to let your smart device get too close to the GTOCP4.  Try to keep the device a couple feet from the GTOCP4.
Please give us feedback on your results.  If this does indeed turn out to be the issue, then we may be able to fix it permanently and more elegantly.
Thanks in advance for any feedback you can give!
