Use a cooling fan to keep the operating temperature of the module within specifications.

2. Outline and Features The AD-4430B has the following features. The weighing module is a weighing indicator that amplifies signals from a load cell, converts it to digital data and displays it as a mass value. This indicator has the following performance : Input sensitivity : ............................0.15 μV / d (d = minimum division) Display resolution : ........................99,999 d in maximum Sampling rate : ...............................1000 times/second Input voltage range : ......................-35 mV to +35 mV (-7 mV/V to +7 mV/V) The calibration using gravity acceleration correction : The function compensates for weighing error due to the difference of gravity acceleration between the calibration place and the measurement place. The digital linearization function : The digital linearization function can rectify and reduce the linearity deviation using weighing points during the zero and capacity setting. Up to four weighing points can be specified. The high-order correction curve is used between each points. Digital span mode : Keying in the load cell output voltage (mV/V) allows calibration to be performed without an actual load.

Installing The Module This section is explained for the environment to install the module and for the terminals of the power source and load cell cable. Refer to each section of options for I/O interface. 4.1. Conditions To Install The Module The module is a precision electronic instrument. Handle it carefully. The operating temperature is -10°C to +50°C. Do not install the module in direct sunlight. 4.2. Power Supply Earth ground the module to prevent electrical shock or indicator malfunction. Before connecting the module to the power source, read the instruction manual thoroughly. Do not connect the module to the power source before the installation is complete. To avoid electrical shock, do not handle the power cable with a wet hand. Earth ground the module. Do not share the ground line with other electrical power equipment. The power requirement is 24 DCV, +10% to -15%. Use a stable power source free from instantaneous power failure or noise. To avoid a malfunction, do not share the power line with other devices. The output voltage of a load cell is a very sensitive signal. Keep all electrical noise sources away from the load cell and load cell cable. Use shielded I/O cables. Connect the cable shield to the F.G. terminal or the module housing. 4.3. Loadcell Cable Load cell cables should have high insulation and shielding performance. Use shielded cables with the insulator that is made of materials with high insulation resistance such as Teflon and polyethylene. NOTE: Teflon is a registered trademark of DuPont. When using the extension cable, we recommend using A&D's load cell cables.

Rod crimping terminal Illustration 4 Cable type

4.4. Shield Cable Connect the load cell shield wire only to the shield terminal of the AD-4430B. As a general rule, No ground is connected between the load cell and the AD-4430B. This is to prevent the ground loop generated by multiple ground points. A ground loop can be created along the wiring route, and interference such as high-frequency noise becomes more likely. 4.5. Connecting Loadcell Cable Shield Cable Connection As a general rule, only connect the load cell cable's shield wire to the module's shield terminal. This is because when there are multiple ground points, it becomes easier for noise to occur as a result of a ground loop. However, when there are higher priorities than noise prevention, such as explosion prevention systems or static electricity release routes, this rule does not necessarily need to be followed. Load Cell Terminal Connections Two types of load cell connection are available: 6-wire connection and 4-wire connection. For high precision and stable weighing, 6-wire connection is recommended. Terminal No. Terminal Name & Function 1 SIG- Load cell input (-) 2 SIG+ Load cell input (+) 3 EXC- Load cell excitation voltage (-) 4 SEN- Sensing input (-) 5 SEN+ Sensing input (+) 6 EXC+ Load cell excitation voltage (+) 7 SHLD Shield 6-wire connection to load cell (recommended) 4-wire connection to load cell (not recommended) Illustration 5 Load cell connection

AD-4430B Type Advantages Disadvantages Description 6-wire connection (recommended) The error is small even when the load cell cable is extended, a thin load cell cable is used, or multiple load cells are used. Complicated wiring Use a 6-wire shielded cable when a summing box is used. 4-wire connection Simple wiring The influence of the load cell cable resistance worsens the temperature coefficient. Prone to the influence of the contact resistance of the connector The error increases when the load cell cable is extended or multiple load cells are used. Precautions to be taken when using the 4-wire connection: If the 4-wire connection has to be used, please take the following measures. Be sure to connect terminals EXC+(6) and SEN+( 5 ) and terminals SEN-(4) and EXC-(3). When lengthening the load cell cable, try to use cable with a large cross-sectional area. Also, keep the cable as short as possible. 4.6. Verifying Loadcell Cable When the load cell connection is complete, perform a connection check using the following procedure. Perform a visual check to ensure that the wiring is correct. Turn the module on. When calibration has not yet been carried out, the display value may be blank. However, as long as there are no problems with the display, confirmation can still be carried out using check mode. Enter the check mode and check the load cell output value. Refer to “7.3.Check Mode" to enter the A/D check mode. Confirm that the displayed load cell output value matches the specified value. Normally the displayed value will be the load cell rated output value or less. If an error occurs, refer to "7.2. Verifying The Loadcell Connections ( DIAGNOS )" or "7.5. Verifying The Loadcell Connections Using Multimeter".

AD-4430B 5.1.9. The Hold Function There are three types of hold functions which can be used for different purposes. Normal hold Holds the value displayed at the time the hold command was received. Peak hold Holds the maximum value reached after the hold command was received. The value will be refreshed if it increases again. Averaging hold This function averages weighing data over a certain period of time and then holds the result. It is useful for measuring things that are difficult to weigh such as an animal that won’t settle down, or for averaging out the weight of an object in an unstable state. In addition, it can reduce the effects of breezes which the digital filter cannot eliminate. Functions Related To The Hold Function Fnc07(Hold) : The type of hold function can be selected. To set operating conditions for the hold function : Set the averaging time length, standby time, or start and stop conditions with HLd01 to 07.

5.3. Calibration 5.3.1. Outline In the calibration mode, the operation to relate the output voltage from a load cell to the mass value and other operations directly related to weighing are performed. Calibration with an actual load Calibration is performed using a calibration weight. Zero calibration : ..................Press key when no load is applied. Span calibration : .................Enter the calibration weight value and place the calibration weight. When the module enters the mode of calibration with an actual load, the tare weight and the zero value will be automatically cleared. Digital span Calibration is performed without an actual load, by numerical input of the load cell output voltage (mV/V). Set the functions related to the calibration. Input voltage at zero : ..........Numerical input of the load cell output at zero. Input voltage of span : .........Numerical input of the load cell output of span. (Load cell output at full capacity - load cell output at zero) Calibration weight value of span : ..........Numerical input of the calibration weight value corresponding to the input voltage of span. ( These value relate the input voltage of span and the weight value.) Dual range The dual range is the display feature that the weighing range is divided into two depending on the value of gross or net and the minimum division is changed. Gravity acceleration correction The correction calculates and corrects for gravity acceleration if the location where the module was calibrated and the location where it is being used in are different. Digital linearization Nonlinearity correction feature to correct weighing errors that occur halfway between the zero point and weighing capacity. Up to 4 points can be input in addition to the zero point, and the intervals between each point will be calculated using curves. Function related to calibration The function stores basic parameters of the module such as the minimum division and weighing capacity and other data directly related to weighing is performed. It includes the parameters for digital span calibration, dual range or gravity acceleration correction is also performed. All data initialization All the data such as zero value, tare weight, calibration data and function data are initialized. All the parameters in the calibration mode is stored in the FRAM.

AD-4430B 5.3.2. The Calibration With An Actual Load (Using A Mass) Calibration is performed using a calibration weight.

5.3.3. Gravity Acceleration Correction When the scale (module) has been calibrated in the same place as it is being used, gravity acceleration correction is not required. A span error will appear if there is a gravity acceleration difference between the place where the module has been calibrated and the place where it is being used. The gravity acceleration correction calculates and corrects this span error by these gravity acceleration correction values for both points (the place it was calibrated and the place it is being used in). Note When the span is calibrated with actual load calibration, the gravity acceleration correction settings are cleared, and the two gravity acceleration settings return to their default values. Functions Related To The Gravity Acceleration Correction CAL26(Gravity acceleration of place of calibration) : The gravity acceleration where the module has been calibrated. CAL27(Gravity acceleration of place of use) : The gravity acceleration where the module is being used.

AD-4430B Illustration 8 Gravity Acceleration Graph 5.3.4. Outline Of The Linearization Function Even if zero and span points have been calibrated, weighing errors may occur between the zero point and weighing capacity. This is a corrective function designed to non-linearly correct weighing errors. It is possible to input up to four points in addition to the zero point. The zero point and each input point will be corrected to put them in a straight line. Areas between input points that could not be corrected completely with straight line correction or with secondary correction will be corrected using a curved line derived from high-order equations. When the actual load input for digital linearization is performed, the calibrated data will be refreshed using zero point and final input point data. It is not necessary to calibrate again.

5.3.8. Error Codes For The Calibration When an error occurs during calibration, the error number is displayed. If calibration is finished without removing the error, the setting values will be restored to the state before calibration. Calibration errors and remedies Error No. Description Treatment C Er1 The display resolution (weighing capacity / minimum division) exceeds the specified value. Make the minimum division greater or make the weighing capacity smaller. The specified value depends on specifications of the weighing system. C Er2 Voltage at zero calibration exceeds in the positive direction. C Er3 Voltage at zero calibration exceeds in the negative direction. Check the load cell rating and connection. When nothing is wrong with the rating and connection, adjust the load cell output as described in the next section. When the load cell or A/D converter may be the cause of error, confirm this by using the check mode. C Er4 The value of the calibration weight exceeds the weighing capacity. C Er5 The value of the calibration weight is less than the minimum division. Use an appropriate calibration weight and calibrate again. C Er6 The load cell sensitivity is not sufficient. Use a load cell with higher sensitivity or make the minimum division greater. C Er7 Voltage at span calibration is less than voltage at the zero point. Check the load cell connection. C Er8 The load cell output voltage is too high when the load of the weighing capacity is placed. Use a load cell with a greater rating or make the weighing capacity smaller. 5.3.9. Adjustment Of The Loadcell Output Add a resistor as shown below to adjust the load cell output. Use a resistor with a high resistance value and a low temperature coefficient. Illustration 10 Load cell output adjustment Because the zero point of the module has a wide adjustable range, as long as there is no problem with a load cell, correcting an output by the module is hardly ever required. Before an output correction is carried out, confirm load cells (deformation, wiring mistakes, contact with anything, or model selection etc.) and connections.
