Thanks Lenny and all you other guys. I pulled the cover yesterday and found a slight gap between the carbon housing (with the spring) and the metal face. I appears that my last guy might not have had...

Heaviwall, I checked and rechecked all the connections. The new board I ordered comes with the new flash memory also. Thats the only way they sell it.

OK, So I went back to the job. Turned on the power, and the board came back on. I even started the chiller and it ran for a couple of days. Then it shut down again, with the same symptoms. No...

I have a Vilter 450XL belt drive, running R22, chilling glycol for an ice rink. It runs around 12# suction. There are 4 of these machines in the plant. This one in particular, lost the shaft seal....

Wow! Mattm, maybe you should have said they are the bomb! Anyway, I went back to the job on Friday and when I powered up the VSD, miraculously, the display came on. I explained to the customer that...

What kind of info on the keypad are you looking for?

Hi, I have a York Optiview panel on a YK VSD with no display. The main logic board appears to be bad. The customer said that the unit tripped and indicated high VSD temp, so he shut off the power,...

I just did the controls on a job with 2 Turbocor's replacing 2 5H120's. They're doing a great job. I believe they run like a York TM, in that they map the wheel, sense any surge, and change their...

On the Delta controllers, anytime you change anything having to do with the dip switches, you have to cycle the power. Try changing the dip switch on the number 2 controller, cycling power, and then...

Hi, The Delta 1280E has dip switches to set it's network address. Also there are a couple of jumpers that determine DNA (dynamic network addressing) and what level of controller it is. Try setting...

I'll look and see if I can find a copy

Thats typical. Here's the info on the controller. http://www.york.com/esglist/pdf/450.20-S32.pdf
You can get a copy of ICE to tie into the panel with from one of your York control friends. It's the...

Hi, I'm looking for some Micro Gateways to hook up three YT R11 chillers to a bacnet system.

Thanks for all the great input. Just to clear up a couple of the items. The rotation is correct. The fluid being pumped is water. The specification on the clearance is .020. I've done a laser...

Thanks for all your input!! I thought about the suction leak, but when I shut down the pump and open the plug on the discharge side, its in a vacuum, from the water draining back down in the lower...

I left out that there is a strainer, basket type. It's clean.

Hi, It's PVC on both sides. The recommended clearance is .015. I moved it to .020 and then I went the other way to .010 with no difference. So I put it back to 15 thousandths.

ITT Gould 3796 self priming pump 10hp. Just had it rebuilt by Gould. Now it cavitates. There's an identical pump next to it that runs fine. This pump had been running fine for 20 years until somehow,...

I have to laugh. Reading the posts about AAM is like seeing a resume for a guy you fired last year and now, after a little spit and polish, his resume reads like the perfect employee. NOT!!! AAM is...

I think the user is aam and the password is system or the other way around

Yes, filling a bottle monthly is on the path to condemnation. Sometimes though, the seal pressure is just a little too high. You can adjust this if the compressor has the adjustable spring on the...

Open? Thats a joke! Unless you're good with Hex decimal, forget it. Their support is horrible!!!!! You can access the AAM with a 232 to 485 converter and a program called Solo Pro. If you don't have...

Very simple to work on and with. Unless they are the old version 2, getting around is pretty simple and intuitive. You'll have to get a hold of a software key unless you log in from their front end...

Andover 256, York ISN, Johnson. Why am I keeping all this junk?

Bryan, Delta's website is http://www.deltacontrols.com

Dongle- I have no idea where the name came from, but they are annoying security devices that plug into your pc for software security. They are either 25 pin that plug into your parallel port or usb....

Orcaview. The program is free, its the dongle that will cost you. The program has both graphics and an Explorer type format for managing all of the controllers and points.

You need to determine what version you're working with. The latest is 3.30. They also have version 2, and version 3.22. Each version requires its own software and they require a software key...

Chillerdude, there is one old Westinghouse on the site, but I don't have the model number. I'm looking for some O & M's. Thanks

The model I have is PFH050 BAAA. They all have the Microtech panel

I'm looking for some literature for McQuay centrifugal chillers. Any info would be greatly appreciated.
Thanks

Common problems? Common you ask?

Lots of times you see breakers tripped or off.

Check the amperage draw on each unit to see if it's really working.

How cold is the return plenum?

What...

Very Nice, Osiyo! I really like how you are to the point on systems problems rather than a one sided view on which platform is better. That's a nice big picture view instead of the myopic "my...

Yes, I've seen their new stuff and they'll still sell plenty of it every year because of the name "York". It's basically the same as before, with some new window dressing. They've added some new...

Walker controls. I saw them at ASHREA for a few years in a row but I didn't see them last year. Al Walker was one of a group of guys that split and started Delta, Walker, Reliable and one other...

Has anyone done a chilled water reset on a Carrier Centrifugal 19dh? It has a 32sm. I was looking for any info on which brand of card they used or the resistance or the connection points on the...

I'm going to hook up a temperature setpoint reset and current setpoint reset on a Carrier 19dg and I'm looking for suggestions on a reset board to use.

I would go with the Danfoss Graham. York used to sell the Hitachi but they had too many problems. The Cutler is ok, but for the money I'd go with the Danfoss.

If you contact New Philadelphia Fan, the Joy reps, they will sell you the SPA. This is a part that replaces the CP. The installation is pretty straight forward. You first remove the CP, then you...

I've retrofitted over 100 Joy fans with VFD's. Mainly Toshiba VFD's. Sizes up to 200 hp. Some of them had bad bearings already and we replaced the CP with a Spa. Measure the pitch angle at wide open...

There's also plenty of BACNET based systems that will do exactly what you're looking for without spending a fortune. We currently maintain several large campuses through their WAN's and LAN's at...

depending on the vintage of the unit, power fault can be a drop of the 110v power below 90v. The other faults attributed to the SSS will show up as Motor controller EXT reset.

I saw a post a while back about a new seal for the centrifugal. Is there a new one for the screw also?
Thanks in advance.

I have a Liebert Mini Mate 2 ton unit about 12 years old that keeps locking out. There's no indication on the board to give a clue why it locked out. Any suggestions on how to trouble shoot or...

Motor controller ext reset indicates the fault is coming out of the SSS. There was a green sheet for a diode problem causing nuisance trips that I'll have to look up. I would lean towards a high temp...

It's very common for a York to act like that. It typically happens when there are parallel chillers and one of them is already running. Whether it's from system depression or the crossover solenoid...

It does sound like a double ender or a sidewinder. I might have something in the office tommorow.

We're looking for a automation tech to work in the LA and Orange county area.
