Warning Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source. Issue The SLO Label shows an incorrect value range for kL. Product Line Field Devices Environment SpaceLogic SLO series Lux sensor Cause The label on the SLO shows the incorrect value range for kL. Resolution SLO: The product specification sheet states the Ranges for the jumper as: - 0 to 500 lx and 0 to 20 kLx The range to 500 lx can be seen on the circuit board. The product’s label shows 0 – 4kL The manufacturer has confirmed the label is incorrect the value should be 500 lx, New labels will be used in production from August 2022.   SLR: The tense delivery situation during the pandemic, especially for electronic components, has forced the manufacturer to make technical changes to the SLR in order to stay able to continue to deliver reliably. The range has extended from 0.4 to 0.5 kLux. These changes are incorporated in the corresponding instructions, provided with the devices. New labels will show the extended range.

Resolution Use the TAC Xenta 102 template

Issue What is the control signal to the actuator for a Xenta 102B? Environment Xenta 102B Cause The 102B is designed to be used with a Belimo actuator. This is why the out signal is not specified anywhere in the documentation.   Resolution The out control signal to the actuator is 0-10V.  

Issue On an existing trend log, the calculation type can be set to the “Meter Consumption”, but this does not generate any log records. Product Line EcoStruxure Building Operation Environment EcoStruxure Building Operation Cause The “Set initial meter” under the “Meter Info” tab has been set to false when the trend log was initially created. Resolution The following image demonstrates the issue. The “Is meter log” is false because in the trend log creation process the “Set initial meter” has been set to false. This causes the “Meter Consumption” calculation type does not generate any log records. To resolve this: Create another Trend log with the “Set initial meter” set to true Or Right-click on an existing trend log (with “Is meter log” = false), press manage meter, configure the required settings, and then press save. This will change the “Is meter log” to true  Now, if the calculation type is set to “Meter Consumption” on the trend log, the log records are getting populated.

Issue Some of the Continuum attributes in b3/i2 objects are not listed for binding in Script, one such example is the ElecValue of an input object, in Continuum, the difference between the Value attribute and ElecValue attribute is the former is the software value while the latter is the actual value read from the sensor. Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Cause For reasons that are beyond the scope of this article, not all Continuum properties have been included for binding in Script   For example, the list of bindable properties for a b3 Analog Input is missing the ElecValue property as can be seen below   Resolution In a b3 Script or Infinet Script Program, there is a way to access any property (attribute as they are known in Continuum) of an object by simply referencing the property's name right after a binding variable to the object's value   Consider the situation that can be seen in the screen capture below...     Due to some strange failure the software contains an incorrect value for the input, but accessing the input's electrical value from a b3 Script program reveals the sensor is reading the room temperature correctly.   Below, screen capture of how this is accomplished in b3/i2 Script program     NOTES "theInput" is bound to the value of the "RoomTemperature" input. "theInElecValue" is bound for output to an AnalogValue in the b3 where the program will place the electrical value of the input We access the property by adding its Continuum attribute name right after the variable bound to the input's value, you will need to know the exact Continuum name of an object's attribute in order to access it this way. This works for any attribute that is accessible by Plain English in Continuum including the PriorityArray of b3 commandable objects.

Issue Disable alarm using the status of another object / point Environment I/A Series G3 Workbench Cause Alarms are not required to be generated when equipment is not running. As an example, alarms should not be generated when the equipment is not running after hours.  Resolution Object alarm extensions have an 'Alarm Inhibit' property which a Boolean object can be linked to. A true value at the 'Alarm Inhibit' prevents alarm generation due to any transition or state change.  The Alarm Inhibit property is within the alarm extension. As such, it is not visible on the parent object and therefore, unlinkable. We can expose properties of an extension by using the 'Composite' function. After adding an extension to a Control object. Right click on the object and select 'Composite'. The Composite Editor window will appear.   In the Composite Editor, expand the object and the extension.   Find 'Alarm Inhibit' and double click on it. Alarm Inhibit will be added to the right of the Composite Editor window. You can rename it if required. Click OK.   The Alarm Inhibit property will now be available on the parent object and linkable from a Boolean object. 

Issue A computer running UltiVist locked up and was rebooted.  Each reboot brings it right back to its locked up state.  How can this be prevented? Environment OS/2 UltiVist Cause A task or program does not execute properly and causes OS/2 to lock up with no response from keyboard or mouse. Resolution Boot up from the installation diskettes to gain access to a command prompt.  On the hard drive, modify the config.sys file to include the following lines: set restartobjects=startupfoldersonly set autostart=programs,tasklist,folders,warpcenter These lines will prevent the computer from running programs or tasks that lead to its locked up state.

Issue A Longtext number is seen when a DI Object is displayed in System Manager when an Alarm is not configured on the object  Environment Sigma Cause A Longtext number is seen when a DI Object is displayed in System Manager when an Alarm is not configured on the object. This does not occur with AI objects. Resolution An alarm on the DI object with Longtext may have been configured in the past and assigned with a Longtext number. To prevent the Longtext from being displayed: 1. Re-enable the alarm, set the Longtext number on the alarm tab to "0" 2. Disable the alarm 3. Download the Object to the controller.

Issue Typically the master controller is at the end of the bus, but is it possible to place it in the middle? Environment AS b3 Cause Depending on the buildings wiring there could be a need to place the AS in the middle of the bus. Resolution The AS can be placed in the middle of the bus, but the terminating resistors must then be placed at both ends of the bus. This method wasn't officially tested in this manner by SQA, but it works similar to how a BCX 4040 does which can be placed in the middle of the bus in this fashion.

Issue Is there a way to activate a function which requires a cause note, action note to be added to every I/NET alarm? Environment I/NET SmartStruxure Alarm User Action Cause Need to document user actions in SmartStruxure when an I/NET alarm changes state. Resolution Create a Change of State alarm and bind it to the I/NET alarm object in SmartStruxure. Create a Change of State alarm. On the User Action page of the alarm configuration attach a Cause Note Group, Action Note Group or Checklist. Bind the alarm object to the Alarm attribute of the I/NET Value.
