Issue Is it possible to remove the folder tree and alarm pane from webstation? Environment Vista webstation 5.1.X Cause Certain users have access to graphics and nothing else. It would therefore be better to be able to maximize the graphic resolution and not see the other panes. Resolution The folder View and Alarm View can be removed by editing the DefaultPage.aspx file. The DefaultPage.aspx file can be found in the folder C:\Inetpub\wwwroot\TACVistaWeb51X.

Issue Vista does not allow the user to edit standard graphics. Attempting to edit a standard object will result in the following error: Environment TAC Vista OGC Graphics Cause Vista does not allow the user to edit a standard graphic file within the vista database. A standard graphic is more of a shortcut to the master graphic in the root directory of TAC Vista Resolution Only make edits to the master graphic within the root directory of TAC Vista.

Issue Airflow reading from Xenta 102-AX is jumping around and will not stabilize or is 0. Environment Vista Xenta 102-AX Plug-in LonMaker, NL-220 Cause For a variety reasons parameters may get changed in a Xenta 102-AX adversely affecting the controller's performance. Resolution Ensure that all of the parameters that affect the airflow reading are set properly. In some cases it may be best to restore the default parameters. Parameters that should be checked may be found through the Xenta 102-AX plug-in or through Vista but are grouped below how they are found in the plug-in starting with Unit Parameters: Unit Parameters Duct Area Ensure that the duct area is set properly for the box size. If a formula was used to determine the duct area from duct diameter verify that it yielded the correct result. For square or rectangular ducts use the following formula: For round ducts use the following formula: Pickup Factor The pickup factor is sometimes known as the K factor and is determined by examining the airflow curve diagram provided by the box manufacturer. It can often times be found on the box itself or in the manufacturer's literature. If the manufacturer's specs cannot be obtained use the default pickup factor, which is 2951.6. Box Constant The box constant is a product of the pickup factor and the duct area. It is sometimes available from the box manufacturer. If the manufacturer's data cannot be obtained use the default value, which is 1588.5. Note that the box constant will be changed from default if a CBC, or, calibrate box constant is performed. Airflow Parameters Velocity Pressure Gain The default settings here are 10 / 10 and are changed when a calibration is performed. If these numbers factor out to be very far from one you may want to reset them to their defaults and investigate if something went wrong with the calibration. For example these values may read 2957 / 3054 but since that factors out to 0.968 which is only about 3% off from one. However, if these numbers were 2957 / 6043 this would be a clear indicator that there was something wrong. Velocity Pressure Offset The default value here should be zero and considering that sensor is nominally set up for a 0-1" scale numbers greater than +0.1 or less than -0.1 should be cause to investigate further for mistakes during the calibration process.

Issue Is there a way to copy the setup parameters from one Xenta 102-AX VAV controller to another? Environment Xenta 102-AX NL220 Cause To assist in commissioning of many Xenta 102-AX controllers with similar configurations, parameters can be copied between controllers. Resolution Locate the controller you want to copy the parameters from. Right click on the controller and select "Copy configuration values to memory" Locate the controller you want to paste the parameters into. Right click on the controller and select "Paste configuration value(s) from memory" Then modify the parameters for that specific 102-AX as normal.

Issue Attempts to make changes to LonMaker drawing results in error message that write access is not available. Environment LonMaker 3.1 Cause When the drawing is opened write access was not granted. By default write access is enabled, but it can be turned off when multiple users are accessing the same drawing file. Resolution When opening the network ensure that the "Show all network options dialogs" checkbox is checked. When you reach the Username prompt screen ensure that the "Write Access" field is checked and then complete opening the drawing.

Issue When using a HyperLink in Vista WebStation graphic page the error message "This content cannot be display in a frame" is shown. Clicking the link to open this content in a new window will properly display the web page. Environment Vista WebStation 5.x.x Cause Newer web browsers support a HTTP header flag named X-Frame-Options which allows the remote web server to block display of its content within a web page frame. This is a security measure to stop "click jacking". Internet Explore 8, Internet Explorer 9 will display the error message Google Chrome will ignore the hyperlink. Resolution Instead of linking directly to the web page link to the folder that contains the Hyperlink object and then clicking on the hyperlink object will open the web page in a new window if the target property is empty or "_blank". Another alternative is simply click the "Open this content in a new window" link.

Issue The Xenta 104-A plug-in limits the temperature value input between 0°F and 18°F. It is not possible to input a negative value. Environment Xenta 104-A Plug-In Lonmaker 3.1 or Lonmaker 3.2 NL220 Cause The Xenta 104-A plug-in limits the temperature value input between 0°F and 18°F. It is not possible to input a negative value. Resolution In Vista follow these steps: Navigate to the Xenta 104-A controller. Browse down to the Node Object function block and find the nciSpaceTempOfst SCPT. Type in the designed space temp offset parameter from the default 32°F value. For example, if a -1°F offset is needed a value of 31 will need to be entered. If a +1°F offset is needed a 33 will need to be entered. 32°F represents zero offset.

Issue The Xenta 104-A plug-in limits the temperature value input between 32°F and 104°F. Environment Xenta 104-A Plug-In Lonmaker 3.1 or Lonmaker 3.2 NL220 Cause The Xenta 104-A plug-in limits the temperature value input between 32°F and 104°F. Resolution In Vista follow these steps: Navigate to the Xenta 104-A controller. Browse down to the 8030 function block and find the nciDischAirMax SCPT. Type in the designed high discharge air temp value.

Issue How to set a Xenta 102-AX back to factory default values.  Environment Xenta 102-AX Vista LonMaker NL220 Factory Default Cause Unwanted changes can be reset back to factory values. Resolution To reset a Xenta 102-AX back to factory defaults, recommission the device and select Source of CP Values to default.

Issue The engine is in the process of converting a database. Internal. NS#165 error occurs when the user is attempting to delete a portion of the LNS database. For example, the error will occur when doing group bindings because the first step in the automated group binding process is to delete the old bindings. The error will also occur when deleting a controller, snvt, bindings, etc, out of the LNS database. Environment Lonmaker 3.2 NL220 Cause All instances of this error have been reported after upgrading an LNS 3.1 system to 3.2, and the upgrade process somehow does not finish. This has been reproduced in NL220 as well. Resolution Send your LNS database to Echelon for analysis at support@echelon.com.

Issue Is it possible to invert an alarm that comes from a BACNET (or other) device via a Xenta 913? The signal is normally closed and the alarm is active when the signal = 0. Environment Tac Vista 5.1.X with alarms that come from devices under a Xenta 913 Cause Some devices have inverted (normally closed) alarm signal. Vista's default is that a signal is normally open. Resolution To invert the alarm signal go to the properties dialogue for the Change of State object and then the alarm tab. Change the Low limit to 0.5 and the high limit to -0.5.

Issue How to configure dynamic text in a Vista OGC Graphic. How do the set values affect the text and color? Environment Vista OGC Graphics OGC Editor Cause The order of the attribute values set in the OGC Dynamic Text editor will affect the operation on the live graphic page. Resolution Start by placing a generic text object on the page using the text tool from the toolbar.  Once the text has been placed on the page, double click it to open the Dynamic Text dialog. Browse to the Vista database value to monitor (ensuring that the Value attribute is selected). Enter the desired threshold values for each text string/color. Set the desired text and color for each value range. The values entered in the Value: dropdown list will act as a true hysteresis. In the above example with values 0, 10, 20, etc, if the value starts at zero, the text and formatting will remain constant until the value rises above 10. At that point, it will take on the text and style defined for 10. If the value drops back down to 9, it will remain unchanged. Only once it reaches the hysteresis value of 0 (or up to 20) will it change again. NOTE: Values defined in the Value: dropdown menu must be listed in sequential order or they will not perform as desired. For example, to add a value of -1 to the list, you would need to redefine all values 0-140 and > to come after the -1.

Issue How can a temperature input be calibrated in a Xenta programmable controller. Environment Menta 5.x.x Cause The sensor input block in Menta does not have any calibration features. Instead these must be done with the program by the use of a calibration value. Resolution Use a PVR block and add this value to the raw senor input value to result in a calibrated value. By making the addition block public and giving it a name it will be visible from a Vista front end. If necessary it can be output as a SNVT as well. In this situation it might be advised to leave the AI block SAT_Raw public flag unchecked to provide a less cluttered view to the end user. While the calibration PVR is left at zero you will see the raw value from the sensor.
