Anyone know what a typical Lennox DAT thermistor curve is? I found a part number C0SNDC00AE1, I believe that its 10k, but what curve? I got a small job that requires me to add DAT sensors to existing...

We're demoing an old job and my field tech is telling me that he can't get the unit disconnected from the damper shaft. I though a manual would be helpful, but this might possibly be the only...

What specific manual are you looking for? They are listed per software version and each individual piece of hardware. For instance WebCtrl 4.1, WebCtrl 5.2, WebCtrl 5.5, InterOp, Supervision, ect.

You need to know your layout first. It could be something as simple as a LAN module offline and the other LAN module works, therefore you see part of the school. It could be a comm problem, if you...

SOME UNIs are obsolete, Uni 16 and 32 are still somewhat around, LGEs are still available too, UNI 59s and 30s are long gone. All of these controllers that you mention are still supported as far as...

WC5.5 does not support it but as stated above, now in Beta. Safari amoung others will be supported

Contact ALPS Controls.com and look up or ask for part number ARC156. That is the low cap wire that we use for ALC 156K baud networking. They have it available from 2 different vendors.

I installed (2) grilles about 8 x 14 end to end in my bulkhead, that opens into the cold air return plenum, above that I have a heavy duty 8 x 12" grille. If you look up in the registers above the...

I have a nice sized wood burning stove in my gameroom, unfortunately if I get a good fire going it is too hot downstairs and I can't get enough to rise. So far I cut a hole in the floor directly...

Glad it worked out! Us old control guys know old equipment .. LOL!

So thet tells me that you are not communicating from the Central Site to the LGE, it has nothing to do with your ArcNet.

In control panel, is your port speed set above the stock connection speed...

Try this while setup on the port that you think is the correct one to go into Control Panel and see what port you should be using.

In Supervision, go to view and make sure that Manual Commands is...

The cable that you have is called a DC99 cable, this is a direct connect cable that talks right to the LGE.

PM or EMail me.

All of your errors are just an indication of no connection. I need to know if you are connected via Direct connect or Ethernet. Do you have an CAT5 wire or an older DC99 15 pin cable connected to the...

I always prefer modulating... floating tends to get lost and needs to be occasionally reset. Modulating is always a % based on control signal, but think of this... If a floating motor is advertised...

Like they said, no database, you're screwed. Most reputable contractors would have left you the ALC install disks and a database, after all, you own both. You're going to have to look around for a...

WC 5.2 is currently only out in Beta but prices are being given, I have seen it once so far, it should hit the street any day now. WC 3.0 is still a usable option, not my favorite, but it works and...

As previously stated, depends on what area is already covered. Here in PA there are only 2 and there is no overlap. You can go on the ALC Website www.automatedlogic.com and "find a dealer", that...

Like I tell my customers who think that BacNet is a do-all integration, the first time that you have to replace a module and download memory, or you need to change a program, you're screwed. These...

Do you have a large network or maybe an old legacy network not talking at 156K? Maybe it just didn't make the loop as quickly as expected, or maybe you have a noisy network? It really should have...

Is your computer showing the correct time? Have you done a time sync? Go to CFG, system settings, scheduled tasks, and click RUN NOW at the bottom of the list. This is of course AFTER you confirm...

So it sounds like you disconnected the plug on the circuit board marked IGM and plugged in the plug marked Intellislot. Did you plug into the Intellislot using the supplied blue cable and set up the...

It sounds like you guys may know something that I haven't heard yet. I have seen WC5.2 Beta and I spend a whole 2 minutes on it to update a licence for a customer. We actually had a seminar on it and...

You can "suck the program" out even when using WC4.1, but you do it while connected to the module using your laptop as a server.

How about this, connect wirelessly with your laptop or even "suck...

I'm a big fan of the Controlair 500DC 3/15# units, but they are 1-9V. I'm sure they have a 4-20 unit too. Careful setting them up, the adjustable pots are REALLY tiny and require a super small...

Oh, I missed that. Yes, I integrate thru a Sitelink which sounds different than what you are using.

I just had the same problem between ALC and Liebert PDUs. We were using a beta driver, it worked for a while and quit. Modscan showed good data but on the ALC side every modbus point, and I'll use...

My first question would be, if you had one what would you do with it? You need the 5 pin Rnet connector that mates with an APT or the newer style USB-L kit. Do you have the database and WebCtrl...

These alarm points can trip intermittant alarms if the alarm buffers are not set correctly. Just because they are set to auto configure doesn't mean that the alarm buffer data comes in right, you...

Our company has been hiring students from a Tech school in the State College, PA area... I'll have to think of the name. We have been very happy with the abilities of their graduates.

We are using a Windows XP machine remote from our server as an alarm screen in a guard station. We wrote a general alarm screen graphic that notifies Security in the event of an alarm, as well as...

Obviously an OEM module, looks like its based on the S6104 but it's not exactly the same footprint. I have never seen one either.

Need more info.... reading zero where, on the computer or on the stat display? What kind of a module is it tied to and what model thermostat?

Some ALC cards will read zero on the system when the...

Max, I'm glad to hear about the change. I know here in my area, it was a problem with some customers.

I have always been for having Liebert on site to do the interface commissioning, especially...

Huhh... I mention this because the Dell default is to shut off the network card when on battery to save power. Usually when you do connect the adapter there is a little message that pops up to...

I just did one of these York Micro Gateway to ALC, easiest Modbus interface I ever did. Assuming that you're doing Modbus, be careful of the multipliers of the inputs and especially the AOs. Output...

This is a stupid question, and I'll deny how I know this....LOL... are you sure that you have the power adapter plugged into the laptop when you try this??? The internal network card shuts down when...

basparky, converting from Legacy Supervision to WebCtrl more often then not creates ??? on your graphics. Draw was forgiving but WebCtrl catches all of those little fopas. Usually an easy fix,...

+1 on the reconfigs... reconfigs indicate network problems. Unfortunately if you're using an LGE, I'm guessing you have a legacy network and you can't see reconfigs.....unless your LGE is Exec B.
...

Email me please....

I haven't seen or heard of its Beta and we were are a branch office. I did however hear that in the new WebCtrl, access databases will be a thing of the past and it will be Sql and MySql only.... :-(

It is written in either Automated Logic WebCtrl or Eikon depending on the vintage of your software, currently their SiteScan Web is basically ALCs WebCtrl 3.0 but it has a few different features,...

I had one customer that had this problem a long time ago. If you click on your time in the lower right cormer of your server, go to TIME ZONE, and then INTERNET TIME and uncheck the box that says...

I stand corrected and that is correct that they will run on a UNI, I forgot about that. I personally have never done it, but I know that it works. The drawback is that you need to out go to and plug...

Setting up the alarms can be a P.I.T.A the first time, once you get it figured out it goes along quick. Send test alarms and look back at your alarm page to view the alarm failure details. When you...

That would be great, my Email is in my profile...

This may not be the case, but look at your backup CD and see if it is all scratched up. If the surface is damaged it will not read properly. In the past I have used plastic polish to buff out or...

I'm thinking that the relay is a latching relay, that would be the only way that the STOP button would work. The START enables the system and the AUX contact maintains the relay coil until the STOP...

Thanks Beenaxed, I appreciate your input. I'm looking for something strictly controls related rather than down to the equipment level. More like a VAV checkout, a server checkout, and AHU checkout,...

I'm putting together some standardized forms for the Techs to use in the field for scheduled PMs. Does anyone have ones that they would be willing to share?
