Resolution In this case someone had rewired the temperature sensor with the x1 and x2 terminations reversed. Once x1 and x2 were wired correctly normal operation resumed.

Issue On a jobsite doing a backup of a GCM and its ASD controllers.  After an upload of the GCM is complete, the ASD controllers appear in the tree (the upload of the GCM created them).  Do they also need to be uploaded individually? Environment TreeTech (any version) Cause Understanding all the steps in a proper / complete upload of a GCM and its controllers. Resolution The first step is to upload the GCM. The second step is to upload each individual ASD controller (Microzone II, Microflo II, etc...).  Each upload will take less than a minute.

Issue Adding Web.Client to an existing site that has Continuum installed with the CFR compliance option. Environment Continuum with CFR Compliance Cause Can't find any part numbers for Web.Client with CFR compliance or an option to add it. Resolution We do not have an option for Web.Client with CFR. One of the requirements for CFR is the inclusion of operator text when performing certain actions; there is no way to prompt for, or supply, this operator text when using a Web.Client browser client.

Issue A MN-Sx sensor is installed more than 200 feet away (the maximum specified) from a MNL controller. The dynamic temperature value drops in and out at the controller.  Is there a repeater that can be installed to improve communications? Environment MNL MN-Sx Cause Cable run extends beyond the specified 200 feet. Resolution There is no repeater available that can be used for the MN-Sx cable run.

Issue Are the 012 NPR’s Broadcast UDP/IP packets utilized by the control network applications? Environment 012 NPR Cause The only Ethernet broadcasts that will be used are standard ARP broadcasts for normal MAC to IP address resolution. The NPR requires a static IP address assignment. Resolution No. The Broadcast UDP/IP packets are NOT utilized by the control network applications.

Issue Does the MNL controller line have any built-in surge protection for main AC power? Environment MNL controllers Cause Design specification Resolution No main AC power surge protection is part of the MNL controllers' design.  It will have to be externally applied.

Issue How do I change the power line frequency setting on the 7716 / 7718 / 7756? Environment I/NET  Hand Held Console (HHC) Cause How do I change the power line frequency setting on the 7716, 7718, 7756? Resolution Physically remove the I/O points from the controller. See TCON 096 for details. Using the HHC, press [Code] , 92, [Enter] to select the AC line frequency Press [Inc] or [Dec] to switch between 50 an 60 hertz Press [Enter] to accept your choice After downloading the software and database, place the external points on the 7716 (or 7718 and 7756) Place the controller on the LAN Note:  Code 92 is not required for any of the 779x Interface's. Entering this code on the Hand Held Console will produce the error LED to illuminate. 

Issue Xenta 100 has a discharge temperature alarm when in heat but the alarm limit can't be set high enough Environment Xenta 100 Cause In several parameters, the Xenta 100 plug-ins set limits on the range of valid entries which are tighter than the limits for that SNVT type. One example is nciDischAirMax on the 104-A. The plug-in sets the acceptable range at 32-104°F (0-40°C). The heated discharge temperature is likely to exceed 104°F. Resolution Open the LonMaker browser on the device Change the setting for the high alarm limit there. Values much higher than 104°F can be entered (limited only by the SNVT type).

Issue When adding a third-party controller to a Vista database, some SNVT values are not present in Vista. The unit commissions and functions properly in Lonmaker, but certain valid SNVTs are left out of the Vista database, such as nvoSpaceTemp on the Trane device. Environment Trane LCI-R rooftop unit Smart Controls SmartStat ST-35F LonMaker Vista Workstation Cause Some information in the XIF did not transfer properly to the Vista database. Resolution Locate the correct .xif file for the device Browse to the device in Vista Right click and select Properties. On the XIF information tab, select the button next to the xif file name and browse in the original .xif file. Refreshing your page values should now reveal all the valid SNVTs in the device.

Issue ZBuilder launches, displays the splash screen, and immediately minimizes. Environment ZBuilder Cause ZBuilder always launches minimized Resolution Do not wait for it to minimize to restore it. Click on the splash screen and that will prevent it from minimizing.

Issue What happens with the output VDC value if the measured value goes outside of the specified range?  Environment SPD310 SPD360 Cause The selected value is specified by the position of the jumper. Signal output is set to 0-10V. Resolution If jumper is set to 500Pa and read value exceeds this value, the output signal will still show 10VDC. Any control signal above 10VDC is marginal, and should not be used as a measurement reference.

Issue Do Sigma Integration Controllers have I/O. Environment IC Integration Controllers I/O Cause Customer requires a small number of I/O where the Integration Controller is situated. Resolution The IC3 does not have any I/O enabled and therefore cannot be used.

Issue When doing a binding using relative path the folder name is included in the binding. When clicking on the relative path button the binding looks like it should without the folder name but it is no possible to save it like that. Environment StruxureWare version 1.3 Cause In the folder name a space was used.   Resolution When taking away the space in the name the relative bindings looked like the should, no folder name in them.

Issue On a jobsite, an energy meter was converted from a pulse output to a voltage output.  Can the analog input be totalized in the associated MNL controller like the pulse input was previously? Environment MNL Cause Changes on-site Resolution Analog values cannot be totalized in the MNL controller.  The next best option is to send the real-time analog value to the area controller (i.e. Niagara UNC or ENC) via a nvo and use the features available at that level for totalization.

Issue PC locks with a GPF error message when modifying a slave time schedule Environment I/NET Time Schedule Editor Slave Time Schedule Cause The master time schedule point that this slave time schedule is referenced with, no longer exists. Resolution Delete the Slave ATS Re-add it with an existing point that has a Master ATS attached.

Issue MSDE Not Installing on a Windows 2000 Professional PC It gets to 98% and then quits without installing anything Environment MSDE Windows 2000 Professional Cause Microsoft network printer sharing settings are stopping the installation from completing. Resolution Open up My Network PlacesPrinter Go to Network and Dial up Connections Go to Local Area Connection Select the General Tab Uncheck the Files and Printer Sharing for Microsoft Networks Retry the install again. Once the software is installed, go back and check that box again so that Crystal Reports will run and print to a printer.  

Issue Customer has an older ENC-520-2 and has run out of memory for his station programming.  His ENC has only 128mb of memory, not the 256mb of memory in the current ENC-520-2 controllers. Environment ENC-520-2 or ENC-520-2-N manufactured in Rockford (SN xxxxxB) prior to BootFlash upgrade. Cause Manufacturing change. Resolution The base memory (128mb) version of the ENC-520-2 cannot be field upgraded to extended memory (256mb) due to other component changes on the controller circuit board.

Issue Database Older than Expected error. Environment I/NET Seven Cause Do you see this balloon error message displayed after an upgrade from one revision to another in the System Tray? This is caused by the database that did not properly upgrade.  Resolution Shut down I/NET and the I/O Server. Go to Program Files, I/NET, Db Create Utility. Select Upgrade Database. Put the SQL Admin password that was created when I/NET was installed. Click Start, in the dialog box, a line would be displayed stating that you are upgrading from build X.XX to X.XX depending on the upgrade. Once finished, restart I/NET again and that message would not be displayed anymore.

Issue The output window in XBuilder will show three different message types: Info Warning Error If an error is occurring during a Generate command, it may be difficult to locate the exact error in and among hundreds of warnings. Environment XBuilder Cause The "Previous Error" command when right-clicking in the output window will take into account both Warnings and Errors. Resolution Right-click in the output window of XBuilder Expand the Filter Messages option Uncheck the options for "Show Info Messages" and "Show Error Messages" The output window will now only show true error messages and it will be much easier to determine the error that is stopping the generate command from completing.

Issue What is the maximum number of site codes that can be loaded into a Continuum system? Environment AC-1 and AC-1 Plus modules Cause Network design limitations Resolution There is no limit to the number of site codes that can be loaded in a Continuum system.  However, each door can contain a maximum of four (4) site codes.  In the case of an AC-1 module, if it loses communication with its associated Netcontroller, it will only allow access from the first two fields.
