Page 8: Transmitter's Functions
Transmitter’s functions Instrument T060E is a weight transmitter with potential threshold relay management function. Therefore, it is not a traditional weighing instrument, since Gross, Net and Tare management functions are not available. Only ZERO corrections can be executed (through external inputs) with the purpose to recover zero derivatives or deviations relative to the weighing system. The onboard relays are managed as alarm relays, therefore they are always kept energized and are de‐energized in ... -
Page 9: Sum Value Function
2.2.2 Sum value function The T060Ei the double channel weighing version (D option) foresees the possibility to handle the sum value of the two channels. The value can be displayed both pushing and in association with one or more threshold relays alarms (see chapter 2.5). In case of systems with capacity or different unit measure, the operator mus realign the value to the same unit measure, deciding which of the two channels must be taken as reference channel. I.E.: Channel 1F.S. 10.00t and channel 2 1000kf F.S. considering channel 1 as reference channel(parameter PRIOR), we should return the channel 2 to a display in t. In order to get this the T060E with parameter MULTIP allows dividing or multiplying the channel value. In our example dividing by 1000 the channel 2 value is displayed as for channel 1 in t. According to different systems capacities, multiplying or dividing, it is possible to sum values with the same measure unit. 2.2.3 Management of the zero The external inputs can be used to reset potential zero derivatives or deviations relative to the weighing system. The ... -
Page 10: Signal Filtering
2.2.4 Signal filtering The instrument allows introducing filtering methods of the signal coming from load cells (FIR filters). This method is based on Digital Signal Processing (DSP) modes and allows handling at best, signals containing strong harmonic components (e.g. generated by mixers). During the configuration phase, it is possible to select three typical filters (with moving average) and 5 DSP filters. The former allow quicker response times but are less effective with regards to interferences, therefore they must be used when extremely quick weight variations must be detected. The latter allow mitigating interferences (since they boast a higher filtering effect) at the disadvantage of the response time to weight variations. In both cases, the higher is the filter’s number, the greater is the filtering effect and the response time to a weight variation. For example, the response to a step weight variation is shown in the chart below, based on the selected filter. The chart shows that filter FIR 1 boasts a response time of approx. 0.2 seconds, while filter FIR 5 boasts a response time of approx. 2.5 seconds. 1710‐ PT060PNE Rev. 0 Page 10 of 57 ... -

Page 28: Management Of The Instrument
MANAGEMENT OF THE INSTRUMENT Introduction T060E transmitter is a programmable instrument able to carry out a series of functions that may be adapted and/or personalized by the user, intended for multiple applications. These functions can be modified through the configuration parameters. Therefore, the instrument must be configured according to the specific application, before being used. All configuration parameters are stored in a non‐volatile memory. The status of the parameter memory is checked when turning on the instrument: in case of negative outcome, the instrument is automatically re‐initialized to the basic configuration and must be re‐configured and re‐calibrated. Operational sequence After performing all connections, the logic operational sequence foresees: The configuration of operational parameters The system’s calibration Selection of the management functions The following management functions are foreseen: CONFIGURATION S et‐up of general parameters CALIBRATION Weight calibration INSTRUMENT TEST Management of test functions To access the instrument’s management mode, press key .

Page 38: Calibration
Calibration 5.5.1 Theoretical calibration procedure In general, the best calibration method consists in applying a known weight (sample weight) on the weighing system. This method is not always possible to execute, when weights boasting a too high mass are used. Other systems implemented, in case of large size tanks, consist of: use of tested litre counters or filling with a specific water quantity. In case of tanks of large capacity, when sufficient calibration weights are not available or geometries do not allow loading large masses, calibration is carried with substitute weights: 1. The tank is loaded with known weight masses 2. The value read by the indicator is recorded 3. The known weights are removed 4. The tank is loaded with the material (or water, or material used by the system) until reaching the weight value indicated in point 1 5. Re‐load the same weights previously loaded in point 1 6. The value read by the indicator is recorded 7. The known weights are removed once again 8. The tank is loaded with the material until reaching the weight value indicated in point 3 9. Repeat steps 1 and 2 until reaching the nominal load, then correct the calibration curve (SPAN) if needed. During the calibration phase, by using known masses, it is possible to check the interferences and errors caused by the application of the load on mechanical parts or load cells. After carrying out the configuration steps of the THEORETICAL calibration (setting of the nominal capacity of the load cells system and relative sensitivity), it is a good practice to check the system’s calibration. Calibration consists of the following steps: Tare with permanent storage Calibration of the zero value Calibration of full scale ... -

Page 41: Span Calibration
5.5.4 Span calibration Before calibrating the span, load the weighing system with the known weight exceeding the full scale by 12.5% and wait until the reading stabilizes. The more the known weight is closer to the full scale value, the more accurate the full scale calibration will be. The system is ready to carry out the calibration with a known weight corresponding to the value of the weight currently on the scale. The operator can modify the procedure by setting directly the known weight value, using keys to increase or decrease the displayed value.

Page 43: Analogue Output Adjustment
5.5.6 Analogue output adjustment The adjustment functions of the analogue output are the same for output under voltage and under current. The adjustment of the analogue output foresees 3 steps: 1. Setting of the analogue scale (FULL SCALE D/A) 2. Zero alignment (ZERO ADJUSTMENT D/A) 3. Full scale alignment (SPAN ADJUSTMENT D/A) The first step defines to which weight value, the maximum value of the analogue output must correspond. For example, the weighing full scale could be 5000, but the maximum value of the analogue output could be set to 3000. This way, for weight values from 0 to 3000, the analogue output will range from 0 to 10 V (or from 4 to 20 mA); for higher values, the output will remain set to the maximum value. Similarly, for negative weight values, the analogue output will remain set to the minimum value. The second phase consists in aligning the analogue output so that zero (minimum possible value) is exactly at 0 V or at 4 mA. The third phase consists in aligning the analogue output so that the span (maximum possible value) is exactly at 10 V or at 20 mA. The ajustment procedure must be viewed on the receiving system of the transmitted analogue signal. -

Page 52: Calculation Of The Checksum
6.2.1 Calculation of the checksum The two ASCII characters which identify the checksum must be calculated in the following way: Calcolate the XO R binary of all the characters from the 1° to the 12° included in the case of strings of 16 characters (ID485 = 0) or to the 14° included in the case of strings of 18 characters (ID485 > 0). Separate the XOR values obtained into a high area (first 4 bit) and a low area (last 4 bit) Code the high area according to the ASCII hex table, which will become the character written in position [CHK 1] (13° character in the case of a string of 16 characters, 15° in the case of a string of 18 characters). For example the binary value 5 (0101) will become character <5> (Hex 35), or the binary value B (1011) will become character capital <B> (Hex 42). Code the lower area according to the ASCII hex table, which will become the character written in position [CHK 2] (14° character in the case of a string of 16 characters, 16° in the case of a string of 18 characters). ... -
