Page 3: Prologue
PROLOGUE Thank you very much for choosing our electronic weighing scale. In order to use this scale properly, we would like to ask you to read these instructions manual carefully. USEFUL INFORMATION The indicator should be placed in a dry place in order to be protected from rain, from getting wet, and it shouldn‟t be exposed to the sun for a long period of time. -
Page 4: Description Of Indicator Ws-3
DESCRIPTION OF INDICATOR WS-3 1) 6 digit LED display Display of weight: “-99999” .. “999999” with adjusted decimal point. Display of parameters, messages, etc. 2) Display LED “0”, it lights when the weight measurement is placed in the minimum weight range, which means that the scale is considered with no weight on. -
Page 5: Keyboard Function
KEYBOARD FUNCTION In the majority of operations, the keys have the following functions: MENU: Enters / Exits the parameters menu for adjustments, cancelation of numerical alteration, return a level back to the menu structure, temporary pause/ cancelation of the weighing process. Equipped with a LED, that lights up / flashes according to the user‟s operations. -
Page 6: System Parameters
SYSTEM PARAMETERS “SYS.Par.”: System parameters System parameters are set on the menu “SYS.Par.”, on which we have access when we press the keys “NEXT” and “MENU” simultaneously for 7 seconds while the system is in weighing mode. “Ad.FiLt” ADC Filter, Converter filter AD The higher the value, the lower the weighing sample rate per second. -
Page 7: Ad.drif." Adc Thermal Drift Correction
“Ad.driF.” ADC thermal drift correction - Thermal drift correction for the converter AD Displayed units per second. Value: 0,0 .. 1,0 Default: 0,0 When it is higher than 0, it eliminates the very slow changes in the indication that usually happens due to the thermal drift of the load cell and the AD converter. -
Page 8: Comm.": Communication Mode
“Comm.”: Communication Mode Communication port function (RS232) Value: 0 .. 5 Default: 0 0 : without communication 1 : manual function, printing of the current weight indication and recording it to the weighting history, by pressing the key “NEXT / PRINT” for a second. 2 : automatic function, printing and recording of the weighing history each time that the scale is loaded and the weight remains stable for a certain time (see next parameter). -
Page 9: Total": Totalizing Weighing
“totAL”: Totalizing Weighing Activates the function Totalizing Weighing. Value: 0 .. 1 Default: 0 When this function is activated, the device shows (and saves to the indelible memory, along with the user parameters) the number of the weighings totalized alongside the totalized weight value. -
Page 10: User Parameters
USER PARAMETERS “USr.PAr.”: User Parameters In the menu “Usr.Par.” we have access when we briefly press the key "MENU". “U.tArE”: User Tare, With this selection the user can choose and set the tare weight, which will be deducted steadily from the weighing and it will be reported in the printings of the weighing. “P._____”: Maximum “empty scale”... -
Page 11: Histor.": History
“HIStor.”: History It is not displayed when printing is not On (System Parameter Print == 0 ). It leads to a sub-menu of 2 choices: “PrInt”: Print, Printing of all saved weighings “CLEAr”: Clear, Clearing of the saved weighings When the printing mode (system parameters, print mode) is set on „3‟ or „4‟, additional events are recorded that can be printed in the specific printing if both the keys „NEXT‟... -
Page 12: Error Codes
ERROR CODES If the device detects any malfunction, the message “Er. X” appears on the screen, where X is the code of the error. By pressing “MENU” the error turns to zero and the device resumes from where it stopped or it performs a restart. -
Page 13: Basic Technical Characteristics
Real Time Clock Error Possible reasons: Similar to error 1. Solution: Time / date adjustment. Records Error Possible reasons: Similar to error 1. Solution: Resetting of records (User Menu - History - Clear ). BASIC TECHNICAL CHARACTERISTICS Power Supply: 10 ... 24Vac, 10 ... 32Vdc (+/- 10% ) Maximum consumption: 250mA @ 10Vac / 10Vdc, 100mA @ 32Vdc / 24Vac Load Cell Type of connection:... -
Page 14: Connections
CONNECTIONS Thread “SERIAL”: Connection of serial port RS-232. Thread “LOAD CELL”: Connection of load cell with 6 cables (compensates the weighing error due to the cable). or Connection of the load cells of 4 cables. The connections S-,S+ should be bridged with the I-, I+ equivalently ( with short cables on the thread ).
