Issue SE7300 and SE8000 room controller fan speeds do not turn off when fan mode is set to auto. When cooling and / or heating is no longer needed, the fan speed remains at low speed. Product Line EcoStruxure Building Expert, Field Devices Environment SE7000 series room controller SE8000 series room controller Cause It is required that the fan be turned off when no demand for cooling or heating is needed. Resolution SE7300 controllers Enter the configuration mode of the room controller. Refer to page 19 of the SE7300 Series Installation Guide for the procedure to enter the configuration mode. In configuration mode, there is a parameter 'AutoFan'. The default mode for this parameter is 'AS'. In order for the fan to stop when there is no demand, the mode should be set to 'AS AD'. AS (Default) = Auto Speed during occupied periods. Fan is always on during occupied periods. Low, medium and high speeds operate on temperature offset from set point. AS AD = Auto Speed / Auto Demand during occupied periods. - Medium and high speeds operate on temperature offset from set point. Low speed operates on demand and will shut down when no demand is present. SE8000 controllers On the room controller, select the fan mode parameter from the home screen. The fan mode must be set to Smart in order for the fan output to function as expected. In Smart mode the fan will turn off when there is no demand for cooling or heating. For SmartStruxure applications of the SE8000 controller This issue can also be seen when binding to the "Value field of the Occupancy Command of the SE8000 controller. Make sure to bind to a priority, not to Value otherwise the fan command will not turn off.

Issue Under rare circumstances, resetting your Manager to its factory defaults may be necessary.  For example, if you have forgotten your Manager's IP address, or if you are experiencing login problems.  Environment SmartStruxure Lite Web Browser SmartStruxure Lite MPM Cause All SmartStruxure Lite™ Managers are equipped with a bootloader, accessible via a special IP address that lets you access several Manager firmware functions, among them, a factory reset.  Resolution WARNING: Restoring your Manager to factory settings should only be performed as a last resort; doing so will erase all its objects and devices, requiring you to reconfigure your Manager from scratch. Accessing the Bootloader As its name suggests, you access the bootloader at boot time, i.e., when you power up your Manager. To perform a factory reset: 1. Disconnect electrical power from your Manager by unplugging its power connector or unplugging its power supply from the AC outlet. 2. Ensure that your computer's TCP/IP settings are on the same subnet as the bootloader IP address:10.50.80.X.     IMPORTANT: Upon restarting your Manager, you will have only a brief interval–approximately 5 seconds–during which you will be able to access the bootloader. As such, we recommend that you perform the following steps 3.  Open your browser and type the following IP address into the address bar, but do not click the browser's Go icon or press any  key on your keyboard: 10.50.80.2 4. Reconnect your Manager's electrical power. 5. Within approximately 5 seconds, click your browser's Go icon or press the key to navigate to the  bootloader's IP address.  The bootloader screen displays.    6. In the Restore factory defaults area, click Submit. The Manager begins restoring its settings to the factory defaults. When completed, a success message displays.  7. Restart your Manager by clicking the Submit button in the Restart system area. 8. You may now log in to the Manager using its restored IP address: 10.50.80.3. If you cannot connect successfully to the bootloader using the above steps, chances are you are not navigating to the bootloader's URL within the defined 5-second window.       As an aid, some users may find it useful to do the following:      Open a command window and type the following: ping 10.50.80.2     As soon as you see a ping reply, return to your browser window and press the key to navigate to the address previously entered into the address bar.   Restoring your Manager to Factory Settings download as PDF.

Issue In firmware 2.19.1, the MPM Modbus Generic Driver feature has been introduced with little to no explanation on how to use it Product Line EcoStruxure Building Expert Environment Multi Purpose Manager (MPM) Cause Sample CSV file not available on MPM Resolution In order to establish communication with a modbus device, a CSV (comma separated values) file of a certain format must be uploaded to the GMC1 object. Once uploaded the file will be visible in the drop-down list.   Requirements and Limitations Only holding registers are supported at this time (Modbus function codes 3 and 16) The CSV file mast be renamed Modbus_[label].csv where label is the name of the device or a label to help identification (e.g. Modbus_SE8000.csv) Write only registers are not supported It is not possible to use a more than 32 bits variable in write mode It is not possible to leave a blank column in CSV register configuration file except the last column It is not possible to create a continuous register table using different variable types   The CSV file must have the following format: modbus_addr,register_type,label,access,factor,unit Download example here (The text file can be viewed in a text editor but its extension must renamed to csv before uploading it to the MPM) modbus_addr: modbus register address (Decimal number between 1 and 65535) register_type: "uint" (UI16) "int" (SI16) "float" (F32) "ulong" (UI32) "int64" (SI64) "uint64" (UI64) label: name for this register, this will also be used to populate the associated object in the MPM Alphanumeric value between 1 and 32 characters. No special characters (comma, simple quotes, double quotes,%,&,@,#, etc.) access: read or read_write. read will only poll register based on driver availability (30 seconds typical) read_write will monitor for a change of value of the associated point, which will then generate a write event to the device with this new value factor: multiplier / gain Float number, typical between 0.001 and 65535. Typical use are factors of 10: (1,10,100, etc) This factor is multiplied when reading and is divided when writing.     unit: BACnet unit, used for the object units in the MPM.

Issue What NEMA or IP rating is a specific product? Environment All devices Cause Is a product protected against water and access by foreign objects? Resolution The Degrees Of Protection document details both the IP rating and NEMA Enclosure charts. The IP rating is made up of 2 digits, the first is the level of protection to foreign objects, the second is the level of protection to water. If a product does not specify any rating for water ingress in it's datasheet then the the second digit will be 0. The first digit relates to the size of a foreign object that can be inserted into the product. Typically many Buildings products will not allow the insertion of a finger (12.5mm approx' 1/2") and offer no water protection, so they would be rated as IP20, however it would be IP10 should they have holes of up to 50mm (approx' 2").
