DFWKR 1. INTRODUCTION This indicator allows to: - quickly view the sum of all the scales, the single scales and the possible combinations (scales 1 + 2, scales 1 + 3 + 4…) - totalize the weight of the axles, obtaining in this way the total weight of the tractor-trailers or the tractor with the trailer. - enter the scales’... -

Page 6: Power Supply & Start Up
DFWKR 5. POWER SUPPLY & START UP The instruments are powered with a rechargeable built-in battery. It is also possible to power through a 12 Vdc tension supplied from an AC/DC external charger (supplied) which should be connected to the 230 Vac mains voltage. Safety norms must be respected for the connection to the mains voltage including the use of a line which has to be free from noise generated by other electronic equipment. -

DFWKR 6. FRONT PANEL KEYS AND INDICATORS indicates that the weight detected by the weighing system is close to zero, within ±1/4 of the division. indicates that the weight is unstable. indicates the presence of the power supply indicates that the displayed value is a net weight. Not used in the application. - Page 8 DFWKR DESCRIPTION Zeros the gross weight displayed on the single scale if it’s within +/- 2% of the total capacity. Depending on the type of tare selected (FModE >> tArE.t parameter, TECH.MAN.REF.): - Tares the displayed weight, switching the display on the net weight - Accumulates the weight displayed in the tare total, not switching the current display.
- Page 9 DFWKR - Prints and clears the accumulated total, incrementing the total of weighed vehicles - Ends an input or output totalisation - Confirms the changes made. Allows viewing the scale’s metric information: capacity, division, minimum weigh for each configured scale. - If pressed briefly it allows to cancel the weigh under way and/or the total tare value entered for the input/output mode.

Page 10: Lcd Display Symbols
DFWKR 7. LCD DISPLAY SYMBOLS The LCD display has symbols which, during the weighing phase, give the indication of the indicator’ functioning status; below is the description for each symbol. FIGURE 5 – LCD DISPLAY NUMBER SYMBOL FUNCTION the weight detected by the weighing system is near zero, within –1/4 ÷ +1/4 of the division. -

NOTE: The semiautomatic tare will be acquired only if the weight is AT LEAST A DIVISION, STABLE (instability ~ led off) and VALID (in other words, the OVERLOAD condition should not be created).

DFWKR vehicle and weigh it again loaded, obtaining (by difference) the weight of the material loaded. ACCUMULATION OF THE WEIGHT IN THE TARE TOTAL The instrument is fitted with a tare total, which is accumulated with each pressing of the TARE key; The reenabling of the weight accumulation function in the tare total depends on the condition set in the “reACt”... -
Page 14: Display Of Metric Data (Info)
DFWKR NOTES: In this condition: - it’s not possible to carry out any weigh acquisition or printing function. - it is possible to switch only to the weight display of the single scales. - With an approved instrument, the viewing with sensitivity X 10 remains displayed for only 5 sec.; once this time has passed one returns to the normal weighing status. -
Page 15: Date/Time Adjustment (Optional)
DFWKR Press ZERO many times (to scroll forwards through the parameters) or TARE (to scroll backwards) until one finds the “irConF” parameter. Press ENTER/PRINT to enter the parameter. With the ZERO or TARE keys select the possible options: “ir no” (disabled remote control), “ir 1” (all the remote control keys function as the TARE key) or “ir 4”... -
Page 16: Printing Of The Heading
DFWKR It is possible to select the language of the printouts: Italian, English, German, French and Spanish (in the TECHNICAL SET-UP >> SEtup >> SEriAL >> PConF >> LAnG). (TECH.MAN.REF.) Printing with NON approved scales. In order to print with non approved scales the following conditions must exist: - the weight must be stable;... -
Page 17: Repetition Of The Last Printout Made
DFWKR 8.12 REPETITION OF THE LAST PRINTOUT MADE Press in sequence the MODE and (info) keys: the last printout made by the indicator will be repeated. NOTE: By turning off the instrument, the information relative to the last printout made, will be lost; therefore this function is not enabled until the first printout is made. -

Page 19: Weighing Operations
DFWKR 9. WEIGHING OPERATIONS 9.1 MODIFICATION OF THE DISPLAYED DATA When the instrument is turned on, the sum of the weights on the connected scales is displayed. To switch from the display of the sum of weights to the one of the single scale, use the keys 1, 2, 3, 4 of the numeric keyboard (1 for scale 1, 2 for scale 2…). -
Page 20: Quick Setting Of Instrument's Number Of Scales
DFWKR Alternatively if one previously set the number of weighed wheels in MODE + 7 WhSubt it is possible to automatically print the subtotal. For example, with a four-platform system, if one wants to weigh a tractor-trailer having 8 wheels (4 of the tractor and 4 of the trailer) and one wants to manually print the subtotal of each section, one should proceed as follows: - Put the tractor on to the scale and press MODE and ENTER after made the totalization: first the weight data is printed and then the subtotal of the tractor;... -
Page 21: Display Of Data Of Weigh Under Way (Only For Totalizer Modes)
DFWKR 9.5 DISPLAY OF DATA OF WEIGH UNDER WAY (ONLY FOR TOTALIZER MODES) In the weighing phase, the 6 key allows to display the data relative to the weigh under way (if not null). The following parameters, which differ according to the functioning mode, are suggested in this order: AXLE WEIGHING OR TOTALIZER MODES tare x: in which x indicates the number of stored tares;... -

DFWKR 9.7 CANCELLING THE WEIGH AND ZEROING THE VEHICLE TOTAL OR VEHICLES TOTAL. The function of the C key depends on the instrument’s functioning mode: WEIGHING WITH AXLE TOTALISATION - BRIEF pressing of the C key: one is asked to zero the vehicle total (CL.SuM?) and then the stored tare total (CL.tAr?); press ENTER to zero, C to exit without applying modifications. -
Page 23: Quick Formatting Of The Weight Data Printing
DFWKR EXAMPLE: to calculate the barycentre of a 4-wheel vehicle with a weighing system having the scales arranged as shown in the figure below, one must position the vehicle on the scales, press the 5 key and enter the following parameters: (INTER AXLE) SCALE 2 SCALE 3... -

DFWKR 3) By pressing ENTER, the formatted weight data is printed (see section 8.9). 4) Take the vehicle off the scale 10.2 WEIGHING WITH AXLE TOTALISATION (for applications in which the NUMBER OF VEHICLE WHEELS > NUMBER OF INSTRUMENT’S SCALES) 1) Carry out a cycle of zero 2) Put the first axle of the vehicle onto the platforms 3) press F: the weight of the vehicle is totalized, and if enabled, the configured weight data is printed. -
Page 25: Input/Output Functioning Mode With Axle Totalisation
DFWKR ATTRIBUTING THE STORED TARE VALUE TO THE INPUT/OUTPUT WEIGH OR TO THE WEIGHT DIFFERENCE It is possible to decide whether to subtract the stored tare value from the input weigh, the output weigh or the input/output difference: Input weight One should enter the tare value before acquiring the input weigh Output weight One should enter the tare value after acquiring the input weigh and before acquiring the output weigh. -
Page 26: Instrument Connected To Battery Operated Printer
DFWKR INPUT ≥ OUTPUT INPUT NET The number of input weighs and the net input total are incremented INPUT < OUTPUT OUTPUT NET The number of output weighs and the output net total are incremented For each of the weighs made, it is possible to automatically print the total weight of the vehicle, see section 9.2 for further information. -
