Issue A space temperature sensor is not reading correctly on a MicroSmart controller (Model # MSC-P-1504).  The type of sensor is not known due to its remote location.  What are the possible values for the SCALE, OFSET, and CVTYP elements? Environment MicroSmart MSC-P-1500 line of controllers Cause Trying to determine the type of sensor installed so a spare sensor can be brought for the service call. Resolution The different combinations of SCALE, OFSET, and CVTYP can narrow down the type of sensor installed (i.e. RTD, voltage, or current).  The exact model cannot be identified remotely.  See page Table 6 on page 17 of the Installation Guide for this controller family.

Issue The customer is replacing a defective actuator on a hot water reheat valve downstream of a VAV box.  The VAV and associated hot water valve are controlled by a DMS MicroSmart MSC-V-511 controller. Can the MF41-6043 actuator be wired into the MSC-V-511 and control the valve? Environment DMS MSC-V-511 MF41-6043 Cause Defective actuator is discontinued and cannot be swapped with an identical, working one. Resolution The triac outputs on the MSC-V-511 can properly control the MF41-6043 actuator. Terminals D1 to D4 provide 24 Vac which is the voltage required for the actuator. Look at the MSC-V-511 installation guide (F-25710) on page 18 for details on how to wire and program the actuator. Remember that the MSC-V-511 provides 24 Vac power so there's no need for an external power source.   If needed, the MF41-6043 installation guide has wiring diagrams on page 6. The actuator requires 2.3 VA. The digital outputs on the MSC-V-511 can provide up to 12 VA.

Issue Proxy objects were successfully created in a G3 obix integration of a R2 station.  The writable proxy objects (ie: setpoint overrides) in the G3 station do not propagate the new value to the native object in the R2 station. Environment Niagara G3 Niagara R2 Cause This is a known issue with the G3 obix driver. Resolution Right-click the proxy object in the G3 station and do a 'forceUpdate'. If there are several dozen proxy objects affected, download this program object.  Paste it anywhere in the Obix Network and execute it.  A 'forceUpdate' will be done to all proxy objects. As of June 2013, these are the most up to date jar files for an obix integration:  2.301.535i.beta.jar, 2.301.535i.beta.jar.pc, and niagaraDriver.zip. Extraction password:  niagara (all lowercase)

Issue A network of GCMs are configured with the NIM card in each GCM to allow intercommunications over the ethernet network. Some (or all) of the devices are no longer communicating.  No known changes have been made to the ethernet network. Environment GCM-86xxx series GCMs with GCM-ETH-1 ethernet network cards The GCM-ETH-1 network card contains firmware version 11.1F. Cause Known issue with the older version of the firmware (rev 11.1F)  where network traffic issues can cause communications failures. Resolution If a firmware upgrade kit (GCMA-149-113) is available you should update the firmware in the NIM card to version 11.2T, using the procedure in document F-26229. In the event that you cannot obtain a firmware upgrade kit or a replacement GCM-ETH-1 NIM card, the procedure documented in Technical Bulletin 99-56, can be used to clear the memory of the NIM card, allowing it to re-establish communications.

Issue I/A Series R2 and G3 Security Update - Oracle has released a Critical Patch Update for Java SE that addresses a number of security vulnerabilities Environment I/A Series R2 - All versions I/A Series G3 - All versions Cause Oracle has released a Critical Patch Update for Java SE that addresses a number of security vulnerabilities.  The patch contains fixes for 50 security vulnerabilities including 44 that only affect client deployment of Java.  These vulnerabilities can only be exploited on desktops through Java Web Start applications or Java applets.  One reported vulnerability exploits the installation process of client deployment of Java – installation of the Java Runtime Environment on desktops.  This Critical Patch Update also includes fixes that were previously released with the Java 7 Update 11 alert (Security Alert CVE-2013-0422). Resolution Download and review TPA-IA-13-0001.01 Technical Product Advisory that details the vulnerabilities.  Schneider Electric recommends that customers evaluate the risk of enabling Java, based on how the affected PC is used and that customers review the download and install the Critical Patch Update as needed.

Issue MNL-V1RVx, MNL-V2RVx and MNL-V1RVx-2, MNL-V2RVx-2 differences Environment I/A Series Micronet LON VAV controllers Cause Part number MNL-V1RVx has been replaced with MNL-V1RVx-2 and part number MNL-V2RVx has been replaced with MNL-V2RVx-2.  The datasheet F-26365 indicates the parts as MNL-V1RVx and MNL-V2RVx.  Resolution The MNL-VxRVx and the MNL-VxRVx-2 are functionally the same. The '-2' was added to the part number to indicate an enhancement to the VAV actuator assembly to reduce the operation noise level of the actuator.
