5 853OpenAirCalibration SoftwareACS931for VAV compact controllers GDB/GLB/ASV181.1E/3 Version 3.10UseThe ACS931 calibration software has been designed for setting and displaying theparameter values with the help of a PC. It is suited for use with the following types ofcontrollers:• VAV compact controllers GDB181.1E/3 (A- and B-series)• VAV compact controllers GLB181.1E/3 (A- and B-series)• VAV controller ASV181.1E/3The connection between PC and VAV compact controller is made via interfaceconverter AST11.Ordering and deliveryWhen ordering, please give name and type reference:Calibration software ACS931The calibration software is delivered on a CD-ROM without interface converter AST11(must be ordered as a separate item).System requirements• Operating system: Windows 95, Windows 98, Windows NT, Windows 2000,Windows ME or Windows XP• IBM-compatible PC, Pentium (66 MHz or higher)• Minimum 8 MB RAM• Minimum 13 MB RAM free hard disk storage• CD-ROM drive• VGA graphics card• Mouse• RS-232 portCM1N5853en19.03.2003Siemens Building TechnologiesHVAC Products

Notes for the userTo be able to run the software, interface converter AST11 (to be ordered as a separateitem) must be connected to the VAV compact controller and the RS-232 port of the PC.The connection between interface converter AST11 and VAV compact controller mustbe made with the connecting cable supplied with the AST11 (refer to data sheetCM1N5852en).When operating voltage is applied to the interconnected devices, the VAV compactcontroller will be ready for operation after about 5 seconds so that parameter settings orreadouts will then be possible.The functions available for selection are matched to GDB / GLB / ASV181.1E/3.Main window “ACS931 – VAV Compact Controller”Menu | submenuMeaningFile | ExitExits the programEdit | PresettingsOpens dialog box "Presettings"Start Opens dialog box "Setting ..."InfoVersion of calibration software ACS931 and softwareversion of VAV compact controllerDialog box "Presettings"...................Group box/buttonsVAVMeaningSimplifies calibration in volume production2/11Siemens Building Technologies Calibration software ACS931 CM1N5853enHVAC Products 19.03.2003

ButtonActionWhen clicking on "Default", a type of box stored indialog box "Presettings" can be called up.When clicking on “Load”, the values for the selectedtype of box set in dialog box “Presettings” will be directlyadopted by the group boxes “Set values” and“Reference values”.When clicking on “Send to VAV”, the values indicated inthe group boxes "Set values" and "Reference values"are downloaded to the VAV compact controller and thenverified.When clicking on the "Read from VAV" button, the datastored in the VAV compact controller will be loaded backto "Set values" and "Reference values".When clicking on the "Save" button, the "Save as"window opens to store the set values and the referencevalues in a data set (free choice of name). Theprocess is ended by pressing the "OK" button.InfoCalibrationWhen clicking on "Open fully" or "Close fully" in this field, waiting time information and –during zero point calibration – status information will be displayed, highlighted in red.Program section "Calibration" facilitates calibration of the VAV compact controller withdirect air volume flow. Here, different modes for the actuator can be used.ButtonActionThe actuator will travel to the fully open position, whichis dependent on the selected direction of rotationThe actuator will travel to the fully closed position, whichis dependent on the selected direction of rotationThe actuator will be stopped...The VAV compact controller will switch to control mode.Note: This mode depends on the parameters set and onthe input signals (Y1, Y2, YC)Forced zero point calibration of the VAV compact controller.When clicking on "Zero point calibration", the text“Zero point calibration“ will appear in the info group boxfor about 1 minute. When this information disappears,zero point calibration is completed and the air volumecontroller is again ready to operate.Text "Zero point calibration" is also displayed periodicallyin the info group box in the case of automatic zeropoint calibration by the actuator of the VAV compactcontroller. As long as this display is visible, the actuatormaintains its current position5/11Siemens Building Technologies Calibration software ACS931 CM1N5853enHVAC Products 19.03.2003

Automatic calibration of the VAV compact controller tothe current air flow at U = 10.0 V. The value ascertainedis loaded directly to the device via parameter"Vn". In that case, all values of the "Set values" and"Reference values" parts are transferred.Example: Applied differential pressure ∆p = 250 Pa;Vnom = 1.00; that is, U = 9.10 V.When clicking on “Calibration to Vn”, the program willcalculate Vnom = 10.0 V / 9.10 V = 1.10. This value willautomatically be entered in the "Set values" and"Reference values" parts under "Vn" and saved in theVAV compact controller.Automatic calibration of the VAV compact controller tothe current air flow at U = 10.0 V × Vmax. The valueascertained is loaded directly to the device via parameter"Vn". In that case, all values of the "Set values"and "Reference values" parts are transferred.Example: Applied differential pressure ∆p = 100 Pa;Vn = 1.00; i.e. U = 5.75 V, Vmax = 80 % V.When clicking on "Calibration to Vmax", the programcalculates Vn = 10.0 V x 80 % / 5.75 V = 1.39. Thisvalue will automatically be entered in the "Set values"and "Reference values" parts under "Vn" and saved inthe VAV compact controller.Benefit: The balancing plant's air supply rate can belowered and the device is calibrated exactly at "Vmax".Automatic calibration of the VAV compact controller tothe current volumetric air flow with the currently entereddigital value "Y". The value ascertained is loadeddirectly to the device via parameter "Vn". In that case, allvalues of the "Set values" and "Reference values" partsare transferred.Example: Applied differential pressure ∆p = 100 Pa; Vn= 1.00; that is, U = 5.75 V, YC = 7.25 V.When clicking on "Calibration to U = YC", the programwill calculate Vn = 7.25 V / 5.75 V = 1.26. This value willautomatically be entered in the "Set Values" and"Reference Values" parts under "Vn" and saved in theVAV compact controller.Benefit: The balancing plant's air supply rate can belowered and the device is calibrated exactly at "Y".6/11Siemens Building Technologies Calibration software ACS931 CM1N5853enHVAC Products 19.03.2003

ControlDigital control is used for the digital or analog preselection of the air flow setpoint.There are 2 modes available:”Y analog” and “Y digital”.On startup, "Y analog" will be activated as the basic setting. Setpoint preselection ismade via an analog signal at input YC of the VAV compact controller.If a change from digital to analog setpoint preselection is made during operation, thewaiting time will be 70 seconds.ButtonActionFor analog preselection of the air flow setpointFor digital preselection of the air flow setpoint.The associated buttons are active only if the followingconditions are satisfied:• VAV compact controller type "con" has been selected• Button "Y digital" in group box "Control" has beenconfirmed• Button "Control" in group box “Calibration” has beenconfirmedThe VAV compact controller maintains the "Vmin" value(Set Values)The VAV compact controller maintains the "Vmax" value(Set Values)The VAV compact controller maintains value "Y".Note that the output signal at “U” depends on theparameters "Vn", "Vmin", and "Vmax"Measured valuesMeasured values are used for display of the actual value, the setpoint, the differentialpressure and the air flow.DisplayActionAir flow output voltage in VoltsAdjusted analog or digital air flow setpoint in VoltsDifferential pressure in PascalAir flow in m 3 /hSettingsDialog box "Info"Text box/spin boxActionManual preselection of the digital setpoint;range DC 0…10 V, resolution 0.05 V.If a change to digital setpoint preselection is made, thesetpoint is to be entered hereThis field is used for entering the number of values(1...10) required for calculating the mean value of the U-signal. This can be used for making the display of thevalue in the "U" field more stable.
