Chapter 4 - Configuration CHAPTER 4 - CONFIGURATION SCOPE The Universal Scale and the Analog Scale do not require any configuration. The DeviceNet scale configuration consists of setting the baud rate and node address on a DIP switch which is accessible through an access port on the bottom of the scale. DeviceNet Communication Configuration NOTE: Be sure to configure the DeviceNet Scale before placing any vessels or containers on the scale.
Any-Weigh™ Series Bench Scales Accessing the DIP Switch NOTE: Configuring the Baud Rate Tilt the scale up until you can reach the DIP Switch access port or if it is more convenient turn the scale upside down so that bottom is facing up to reach the DIP Switch access port. Scale must be connected to earth ground from the Chassis Ground Attachment Point. (See Fig. 4-1) Refer to Table 4-1 to configure the baud rate.

Chapter 5 - Setup CHAPTER 5 - SETUP SCOPE All information contained in Chapter 5 pertains to software or firmware settings or procedures to prepare the DeviceNet Scale for calibration and operation. Alternatives to these procedures either explicit or implied, contained in this section are not recommended. It is very important that the user and service personnel be familiar with the procedures contained in this chapter, before going through the setup procedures.
Any-Weigh™ Series Bench Scales NOTE: 5-2 By selecting OFF (0) or 1 the scale increases the updates per second from 10 to 55. • Parameter 3 = Calibration Type 0 = Hard Cal, 1 = C2 Cal, Other = Not Cal’d (Read Only) Length in Bytes = 1 • Parameter 4 = Span Weight in Lbs 1 to 2147483647 10000.
Chapter 5 - Setup • Parameter 21 = Calibrate High Command 0 to 1 (Set to True to Complete Command) Length in Bytes = 1 • Parameter 22 = Calibrate using C2® 0 to 1 (Set to True to Complete Command) Length in Bytes = 1 • Parameter 23 = Span Weight in Kgs 0.000 to 2147483.647 0.045 Length in Bytes = 4 • Parameter 30 = Net Weight in Kgs Read Only Length in Bytes = 4 • Parameter 31 = Gross Weight in Kgs Read Only Length in Bytes = 4 • Parameter 32 = Tare Weight in Kgs -999999 - 999999 0.
Any-Weigh™ Series Bench Scales imal places in the 32 bit integer weight outputs. The value 0 causes these weight outputs to be in floating point format. NOTE: This applies ONLY to the weights as viewed through the I/O (Command) interface. The explicit message interface continues to use 3 decimal place 32 bit integer format only. • Parameter 38 = Write non-volatile command. Length in Bytes = 1 Setting this parameter to 1 will cause a save to non-volatile memory.
Chapter 5 - Setup Most of the DeviceNet Scales’ parameters are only 1 byte long, making it possible to write them with a single command. There are also some 4 byte parameters. To write one of them: Step 1. Step 2. First write the 2 most significant bytes, using a WRITE command as described above, with 0x27 in the parameter number field. Write the least significant bytes using normal parameter numbers.
Any-Weigh™ Series Bench Scales 1. 2. 3. 4. First byte of first word on the input data is the new valued wanted. Upper byte of first word should be 0 and is not used. Lower byte of second word is the parameter number. Averages is parameter #5. Upper byte of second word is set to “1” to indicate write. This causes the unit to write the value in the first byte of the first word to the Averages parameter. During the execution of the command, the output polled data reflects the input polled data.
Chapter 6 - Calibration CHAPTER 6 - CALIBRATION About Calibration of the DeviceNet, Analog and Universal Bench Scales The DeviceNet and Analog version of bench scales come pre-calibrated from the factory. For the Universal version make sure it is correctly wired to the weighing instrument/indicator. Refer to the weighing instrument/indicator manual for calibration instructions. C2 Second Generation Calibration C2 electronically calibrates a scale system without the need for test weights.
Any-Weigh™ Series Bench Scales THE BUTTON® Enables one-touch electronic calibration of the scale when it is empty. Access to THE BUTTON and associated Module LED is located at the bottom of the scale through an access port. (See Fig. 6-1) Connector Dip Switch The Button Module LED FIG. 6-1 THE BUTTON LOCATION/BOTTOM VIEW Step 1. Make sure that there is nothing in the vessel or on the scale. Step 2.

Chapter 6 - Calibration volt (of transducer excitation) will be represented by the 4-20 mA output range. The gain can be adjusted from 3 mV input per volt of excitation to as high as 0.8 mV input per volt of excitation. This broad range of sensitivity allows for the wide variation in transducer range that remains after dead load compensation is subtracted by the Coarse Zero adjustment.
Any-Weigh™ Series Bench Scales Step 6. Adjust the SPAN for 20 mA (2 V) for fullscale weight. For less than full-scale weight, perform the following steps: 1. 2. 3. 4. • Divide: calibration weight/fullscale weight = (F)raction of full scale. Multiply: (F)(16 mA) = 1, the current caused by the calibration weight. Add: 1 + 4 mA = Calibration Current, 1c. Adjust SPAN to produce the Calibration Current, 1c, in the output/ power loop.
Chapter 6 - Calibration removed, or it can be left in the circuit for future measurements. Neither action will interfere with the system operation.
