WEL User Manual 4.0.3. (WEL_User_Manual_4.0.3.pdf)  [Friday, 03-Jun-2011 14:33:22 EDT]

This updated WEL Users Manual was created to:

  • Document the new WEL 4.06+ Firmware Features
  • Document the new new hadeware features of the WEL 4.3 Processor board.

LocateIP (LocateIP.exe)

If you use DHCP to automatically assign your WEL unit an IP address, you may not know how to find it with your browser.  Locate IP is a neat windows program that will go out and find the WEL, and let you see (and modify) it's IP address.

Wiring tips for WEL sensors (WEL_Wiring_Quick_Tips.pdf)  [Wednesday, 07-Nov-2012 13:15:05 EST]

This is a short document that summarizes how to hook up the various WEL sensors. 
It describes the standard wire color-code and explains the signal polarities.

WELSTAT-8 user Guide (WELSTAT-8.pdf)  [Wednesday, 25-Jul-2012 07:30:57 EDT]

This explains the operation of the WELSTAT-8 Module. This module provided 8 Isolated "thermostat syle" inputs. These can sense the presence of a 9-28V AC/DC control sisgnal.

WELPULSE-6 user Guide (WELPULSE-6.pdf)  [Wednesday, 25-Jul-2012 07:30:56 EDT]

This explains the operation of the WELPULSE-6 Module. This module provided 6 pulse counter inputs. These can interface to "rate" type sensors like Wattmeters, water and gas flow meters or any rotational sensor.

Net metering and PV monitoring. (NetMeteringWhitePaper.pdf)  [Sunday, 16-Sep-2012 19:41:44 EDT]

This document explains how to determine the calibration scale factors when using a Wattnode Wattmeter with the -PV option. It also describes how to combine pules values to calculate net power usage.

Image refresh scripts (WEL_images_refresh_scripts.doc)  [Tuesday, 24-May-2011 10:21:05 EDT]

Your live system image and trend graphs are created and displayed on an automatically-generated page on the WELServer server.  But if you have your on web site, then you may want to include them there as well.  Since the images are continually updated by the server, it makes sense to have them automatically refresh on your web page.  This file explains the best way to get your images to refresh automatically.  It's just some simple Java Script that can be cut & pasted into your page.

Standard Sensor Names (WEL_Standardized_Sensor_Names.doc)  [Monday, 20-Nov-2006 12:45:21 EST]

One part of configuring the WEL is to give all your sensors names.  These names are used to define your system graphic and trend graphs.  This document suggests a standard naming convention.

Sample logfile (WEL_log_2008_09.xls)  [Tuesday, 02-Sep-2008 08:28:10 EDT]

This is a sample Log File. It contains just over a day's worth of data for eight devices. Each row for the file is one Data Post.  The row starts with Date and Time and then follows with each device that is listed in the Log Order section of your Owner Setup, separated by tabs.  Although the file has an .XLS extension it's really just a text file, but the .XLS extension causes Excel to be run when you double click the file.

 


Software Updates

User Software-Updates are possible on any WEL board running code version 2.0 or greater. 
This process requires you to download the Update Manager program and the latest WEL binary image
Once you have these files, follow the directions on the Software Update Page.

Update Manager program (UpdateMGR.exe)  Rev 1.8   [Friday, 24-Apr-2009 02:01:24 EDT]

This is a Windows XP program that locates the WEL on your network, then enables you to load the new binary image into the on-board flash.  The existing image can be saved on the WEL as a backup in case there is a problem with the new image.  Download this program and put it in a "WEL_Update" folder on your hard drive.  Add a shortcut to the program on your desktop.

Note:  If you have downloaded this program before, make sure you download this latest version if you are updating WEL firmware 2.16 or above.

WEL Binary Images:

There are currently two different paths for WEL firmware upgrades:  Firmware versions 4.X which run on the current WEL4.X hardware, and Firmware Versions 2.X which run on the legacy WEL 3.X Hardware.  Bottom line.. you must stick with the path that is already on your WEL Board.  So, if you have 2.16, you can upgrade to 2.18, but not 4.01.  Likewise if you have 4.01, don't try going to 2.18. 

TIP: When you go to the WEL's main page, it displays the current version in big print at the top.
