Issue Step-by-step instructions for calibrating airflow on a Xenta 102-AX (or I/NET MR-VAV-AX) using the M/STAT. Test and air balance procedure for balancing airflow Product Line EcoStruxure Building Operation, TAC INET, TAC Vista Environment Xenta 102-AX MR-VAV-AX M/STAT Cause The preferred method for calibrating airflow in Xenta 102-AX or MR-VAV-AX is through the plug-in.  However, this is not always an option, especially when the responsibility for calibrating is given to a third party test and balance company.  Pocket references exist for navigating through the M/STAT menu, but there aren't clear step-by-step instructions to tell exactly how to perform the calibration. Resolution Click here to download this document in Microsoft Word format Connect M/STAT Plug the M/STAT into the jack on the thermostat. The initial display shows the set temperature.   Enter Password Press the Service button. This prompts you to enter the service mode password. Default password is 183. Use the +/- keys to set each digit and the enter key to submit. If the password is incorrect, the display will blink. Airflow Parameters If the password is correct, the first menu option – Unit Parameters (UP) – is displayed. Hit the select button down twice until Airflow Parameters (AP) is displayed. Press enter. Cooling Low Flow Setpoint The first option is Cooling Low Flow Setpoint (CLF). Press enter to view the setpoint (divided by 1000). Record this value. Press the service key to escape out of the menu. Cooling High Flow Setpoint Navigate to Cooling High Flow Setpoint (CHF). Press enter to view the value (divided by 1000). Record this value. Press the service key to escape out of the menu. Reset Factory Calibration Navigate to Factory Calibration Settings (FCS) and press enter. Use the change keys to display “YES” and press the enter key. This will set the box back to default settings. This is a good idea to do prior to every calibration. Press the service key to escape out of the menu. Calibrate Low Airflow Navigate to Calibrate Low Airflow (CPL). Press enter and the current airflow is displayed. Wait for the airflow to reach the CLF and level out. Once the value is steady at setpoint, press the enter key only once. The display does not change. Enter Actual Low Airflow Measure the actual airflow. Use the change keys to set the display value to the measured value. Press the enter key. Choose One or Two-Point Now Calibrate High Airflow (CPH) is displayed. If one-point (offset only) calibration is desired, press the service key to escape out of this mode and calibration is complete. If two-point (gain and offset) calibration is desired, press enter to continue to the next step. Calibrate High Airflow The current airflow is displayed again. Wait for it to rise to meet the CHF and level out. Once the value is steady at setpoint, press the enter key only once. The display does not change. Enter Actual High Airflow Measure the actual airflow. Use the change keys to set the display value to the measured value. Press the enter key. CPH is displayed again, this time as a general menu item. Escape Service Mode Press the service key to escape out of the menu. If you are finished configuring the box, escape all the way back out of the service menu before disconnecting the M/STAT. Disconnecting in configuration mode can leave the stat displaying “00” or other incorrect numbers.

There is an incorrect or out-of-date program version. (Subsystem: NS, #38) for resolution. Product Line TAC Vista Environment LonMaker 3.X Xenta Servers Xenta 511, 527, 701, 711, 721, 731, 913 XBuilder Cause The Program ID inside the controller does not match the Program ID specified for that controller inside the LNS environment resulting in a Program ID mismatch. Program IDs are unique identifiers created for use in device templates and are based on the XIF. Resolution Resolve the Program ID mismatch by making the Program ID in the controller match that in the LNS environment. Download the controller using XBuilder. Send project to target. Generate the latest XIF for the XBuilder project. In the Network Pane, right-click on the root (TAC_Xenta_511 in this example) Select Generate XIF File   Find the new XIF that has been generated in the XBuilder Project directory: targetimage\configdb\lon\TAC_Xenta_511.xif Default XBuilder locations XBuilder 5.1.3 and prior: C:\Documents and Settings\All Users\Application Data\TAC\TAC XBuilder Projects XBuilder 5.1.4 and later: C:\Documents and Settings\All Users\Application Data\Schneider Electric\TAC XBuilder Projects Windows 7: C:\ProgramData\Schneider Electric\TAC XBuilder Projects A good practice is to view details of the folder to confirm the time stamp of the XIF file. It should match the time that the file was generated in XBuilder. This file will be selected later, so another good practice is to rename the file to something more meaningful -- the name does not matter. "WebServer.xif" may be easier to find later and confirm it is the correct file. It is also perfectly acceptable to move this file to a new location -- Device Files of your overall project, for example. That can also help in later steps, especially if the default XBuilder Project location is used. In LonMaker, right-click on the device, and choose "Replace" (Not in System Plug-In)   Browse to the newly generated XIF file. Give the new device template a name. Select Finish. Commission the Xenta 5/7/9xx into the network. The Program IDs now match and the error is cleared.

Issue Troubleshooting 2-Output PWM on a Xenta 102-AX Floating actuator for heating applications (hot water valve) Product Line TAC Vista Environment Xenta 102-AX PWM_2 floating hot water valve actuator Cause Multiple causes legitimately keep the hot water valve two-out floating control from stroking. Resolution The Xenta 102-AX controller supports auxiliary heat with two outputs. Both outputs can be utilized in a 2-output pulse width modulated (PWM) signal for control of floating actuators. This document suggests troubleshooting techniques to help narrow down the cause of improper operation of these hot water valve outputs. Start with Universal Output #2 On the Status tab of the 102-AX Plug-in, each of the universal outputs are listed under the “Network Bound Inputs” column. In the 102-AX Plug-in version 5.1.4, this column has been erroneously omitted. Download TAC Toolpack version 5.1.4 Hotfix 72 from the Buildings Business Extranet to resolve the issue. The output that represents the 2-output PWM is Universal Output #2 only. Even though output #3 is involved in the process, only #2 in the Plug-in represents the actuator position. The first thing to do is override the output to three different positions: 0, 50 and 100%. Cycling between three different values ensures the actuator is actively stroking. Forcing the valve to 100% will cause the open signal to energize for the full stroke time (throttling range) of the actuator, after which it will be de-energized. Wiring problems discovered after this time period has elapsed would require the output to be forced to 0% and then back to 100% to energize the open signal for the full stroke time again.   Figure 1. Network Bound Inputs If the valve strokes correctly, then the unit parameters, wiring, and actuator are all correctly configured. Skip directly to the chapter entitled “Overriding the Output Successfully Stroked the Actuator.” If the valve did not successfully stroke, proceed to the next chapter where three possible problems are addressed. Overriding the Output Failed to Stroke the Actuator There are three main reasons why overriding the output would fail to stroke the actuator. Unit Parameters The Unit Parameters tab of the 102-AX Plug-in is where Universal Outputs #2 and #3 are configured to work in tandem to accomplish 2-Output PWM control of a floating actuator. Heat 1 configures both outputs when OUTPUT_PWM_2 is selected. There is no need to configure Heat 2. Changes to Heat 2 will have no effect on the heating operation.   Figure 2. Heat 1 Unit Parameters Make sure the output type is set for OUTPUT_PWM_2. The stroke time should match the manufacturer’s documented stroke time of the actuator. Delay on start and stop are dictated by user preference or customer specifications. Normal Stroke should be set for normally closed. Wiring Check the wiring of the actuator to the 102-AX. It should be wired as follows: Point Label Terminal Actuator Universal Output #2 V2 15 OPEN Universal Output #3 V3 16 CLOSE Ground G0 13 COM Actuator The last step to troubleshoot an issue with the actuator not moving is to test the actuator itself. This can be done by jumping out the open or close leg of the actuator to 24Vac power. If the actuator still does not move then it is faulty and should be replaced. Overriding the Output Successfully Stroked the Actuator If overriding the output causes the valve to move accordingly, then the configuration of the output and the physical configuration are all correct. The 102-AX controller logic is not calling for the valve to open. There are a number of reasons why this might be occurring. The Basics The 102-AX must be in a heating mode to open the valve (cooling mode will close the actuator). It may be displaying either HVAC_HEAT or HVAC_MRNG_WARMUP. The space temperature must be below the effective setpoint to be in heat mode and will generate a negative terminal load down to -100%. The terminal load will equal the heating valve position. Check that the heating/cooling setpoints and heating/cooling bands are set such that no overlap in the two modes occurs. Heating/cooling bands must be greater than 0°. Hardware Configuration If the 102-AX is not configured for a sufficient number of stages of heat, it will not cycle the valve. If there is no fan, then only one stage of heat needs to be defined. However, if a fan is defined, then there needs to be at least two stages of heat, because the fan is considered the first stage.   Figure 3. Fan Type and Heat Stage If the heating valve is to be utilized in morning warm up mode (when the duct inlet temperature indicates that the air handling unit is providing central plant heat), then the hardware configuration must state that supplemental heat is allowed during warm up.   Figure 4. Enable Heat on Warm Up If a supply temperature sensor is wired to Universal Input #1, it could be that it is sending the VAV into morning warm up mode when the heat is enabled, and thus, disabling the heat. If this is the case, there are two options. Universal Input #3 can be used instead and set as an outside air temperature. Alternatively, Universal Input #1 can be configured as "None."   Figure 5. Input 1 Selection Setting Input 1 Selection to "None" will not disable the reading of the sensor. UnivIn1_Sense.nvoAuxTemp1 will continue to report the duct supply temperature. Setting it to "None" disables the signal from affecting the internal logic – preventing the 102-AX from entering morning warm up mode. Note: If the VAV is already in morning warm up mode when the input is set to "None," the box will remain in morning warm up mode. Override the input temperature to something below room temperature prior to changing the input selection. Application Mode The SNVT input VAV_Controller.nviApplicMode can allow a supervisory controller to override the current mode of the VAV. Upon receipt of a new application mode, the 102-AX will encounter a brief synchronization period where the terminal load is held to 0%. If the SNVT is being sent from a data manager, and the period on the output SNVT in Menta is set to 60 seconds, then the 102-AX will zero out the terminal load every 60 seconds, preventing proper operation. Set the SNVT output to a period of 0 seconds, and it will only write a new value on change and allow proper external control of the mode. Airflow Setpoint The Warm up Maximum airflow setpoint must be greater than or equal to the Heating Minimum airflow setpoint.  If this is not the case, then the airflow setpoint will default to the unoccupied flow setpoint (typically 0 CFM) any time the VAV is in heat mode, and the heating output will not be utilized.  This can be easily overlooked in applications where Warm up Mode is not being used, but this one parameter must still be set. This is fixed in the Xenta 102-AX firmware v2.18.   Figure 6. Airflow Setpoint Actual Airflow In order for the heating outputs to be energized, the airflow must be at least 80% of the minimum heating airflow setpoint. This is hard coded into the controller and cannot be disabled. The only way to remove the interlock is to set the minimum heating airflow setpoint to 0 CFM; however, in this situation, the VAV will close the damper in an attempt to provide 0 CFM of airflow. The heating will modulate without any airflow at that point.   Figure 7. VAV Status not providing 80% Airflow Check on the VAV Status tab of the 102-AX plug-in to compare the airflow to the airflow setpoint. If the box cannot provide the necessary 80% of setpoint or there is no airflow available during the commissioning stage, lowering the airflow setpoint can allow checkout to continue. This 80% airflow requirement is looking at the on-board flow sensor of the Xenta 102-AX. If the flow value is coming from another controller on the network via the nviBoxFlow SNVT, the heat will be disabled. The nviBoxFlow input will override flow values for damper control, but heating outputs will ignore it. In this situation, setting the pressure offset (UCPToffsetPress) to 1” will bypass the limitation. This will be fixed in the Xenta 102-AX firmware v2.18. Wrap Up If everything is configured properly physically and in the 102-AX Plug-in, then the box should be stroking the valve to maintain the space temperature setpoint.

Issue   PARSER_CODE_ERROR Error in COD file - Error:15 When directly downloading a Menta file a Parser Code Error is displayed. This is a Parser Error that is alerting you to the fact that there is a problem with your Code. An error in the Menta file is stopping it from downloading successfully. Product Line TAC Vista Environment Menta Xenta programmable controllers Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B Cause Direct downloading a Menta file (via the RS-232 port, a serial cable, and Online Simulation Mode) can bring to light Parsing Errors that are not reported by the System Plug-in. These errors will result in unsuccessful download attempts without any indication of the failure. To find them, direct download the Menta file. The download gets to where it is parsing the file before it fails:  There are three known reasons why the parsing of a Menta file will fail with Error Code 15. With some careful investigation of the error the cause can be determined, although checking all known causes is not prohibitively time consuming. Either the Menta application is too large, contains SmartStruxure Function Block following a cut-and-paste of code, or the file has corrupted public values indicated by the values being shown in scientific notation. Resolution First, determine the source of the error. Three known issues are discussed below: Corrupted public values show in scientific notation The Error:15 window attempts to show the user where in the Menta code the error is occurring. Without a fairly intimate knowledge of the inner workings of Menta, this can be less than helpful. However, if scientific notation in a PVR is causing the error, the error window will show this. The first line states: PVR     3,Z4 R1.0762e-042 This is showing that a PVR in the Menta program has a value of 1.0762e-042. It may take some searching, but you will need to locate the PVR in the Menta file that has this corrupted value and change it back to something valid. Also check public constants in the file to make sure they are not corrupted.   SmartStruxure Function Blocks in TAC Menta application This error also appears if there are any SmartStruxure specific Function blocks in the application. RO, BO, RI, BI, TSCHI, ERROR, II, IO, PI, PO Check the if any of the blocks are in the COD file (in the error window), find the blocks and replace/remove them.   Menta Application is too large The only other option is that the Menta application is too large. So if the Error:15 window comes up and does not indicate scientific notation in any of the values, it has to be that the file didn't fit inside the controller. Check the memory in Menta under Options > Memory Usage. You want to see free space in all categories. If there are any negative numbers then that portion of the application is too large. Bear in mind that this is a simple estimation by Menta as to the memory needed. Trend logs, OP tree, network description files and the Menta application all need to be stored in the controller, so sometimes a very low, albeit positive, number can indicate problems as well. Try cutting down on trend logs or OP trees to free up space if the application cannot be reduced.

Issue   Invalid database version. (Subsystem: LNS, #81)[DB #-2038] Environment LonMaker 3.1 Cause A computer running LNS version 3.2 or higher (sometimes called LNS Turbo) can open any LNS database. If the database being opened is LNS version 3.1 or earlier, the database will be upgraded. This process is irreversible. Once the database is upgraded, earlier versions of LNS can no longer open it. The opposite is not true. If a computer running LNS version 3.1 attempts to open a 3.2 database, this error will appear. Resolution The LNS version must be at 3.2 or later to open a 3.2 database. Either upgrade the LNS version on the PC attempting to open the database, or revert to an earlier version of the database before it was upgraded (if possible). To upgrade your LNS version to 3.2: Navigate to http://echelon.com/support/downloads. You will need an Echelon ID and password. It is free to create a New User Account if you do not already have one. In the drop-down menu, select Search for software in the Network Tools category. Before you install LonMaker Integration Tool 3.1 Service Pack 3 Update 3, you must have already installed LonMaker Integration Tool 3.2 Service Pack 3 Update 1. Download both Update 1 and Update 3, or just Update 3 depending on the situation. Note: If you upgrade to LNS Turbo, you will no longer be able to restore databases from a non-Turbo LNS PC. There is backwards compatibility with old databases, but no "forward" compatibility for older PCs to open newer networks.

Remove the encryption or compression flags and apply then reinstall. If the PC operating system is Windows 7 64-bit, install Vista 5.1.5 or higher. Resolution below will not solve the issue. In most cases this is caused by MSXML 6.0 parser. This software is commonly installed by programs using SQL, and also during the TAC Vista installation. If this can't be removed using Add/Remove Programs, you can download a program from Microsoft that cleans up and removes this software (and others). It is called Windows Installer Cleanup. Link to download: msicuu2.exe. NOTE: Microsoft recently removed this utility from the downloads section of their support site. They have this to say about the utility: While the Windows Installer Cleanup utility resolved some installation problems, it sometimes damaged other components installed on the computer. Because of this, the tool has been removed from the Microsoft Download Center. Use this utility with care at your own risk.   In most cases TAC Vista will install successfully after removing MSXML 6.0 parser.

Issue SP-RDM2 Reader Expanders running firmware 1.12.544 appear to fail whenever an attempt is made to update their firmware revision. Product Line Security Expert Environment SP-RDM2 SP-RDM2m Cause There is a known defect in 1.12.544 (Build .544) which prevents the SP-RDM from being upgraded or even downgraded. However, a number of SP-RDM units have been shipped from the factory with this build pre-installed. Any attempt to select an SP-RDM running this firmware and upgrade or downgrade it to a different revision will consistently fail with an Error: 'Module not responding'. There is also a possibility that the SP-RDM can be permanently disabled in the process Resolution Since the .544 Build Defect cannot be resolved the only recourse at this time is to swap out the unit via the Returns Material Advice (RMA) process for a new unit.      Note: All other SP-RDMs running firmware both above and below .544 Build are unaffected
