2. Introduction The AD-4406 is a compact weighing indicator that amplifies the signal from a load cell, converts it to digital data and displays it as a mass value. This indicator has the following performance: Input sensitivity: ......................... 0.2 µV/division Maximum display: ...................... 40000 divisions Display update rate:................... 10 times/second approximately Input voltage range: ...................
3. Installation and Precautions 3.1. Installation and Precautions The AD-4406 weighing indicator is a precision electronic instrument. Handle the indicator carefully. The operating temperature is -10 to +40 (14 to 104 ). Do not install the indicator in direct sunlight. A malfunction or other problems may be caused by an unstable power source including momentary power failure or instantaneous noise. Use a stable power source.
3.3. The Load Cell Connections Connect the load cell wires to the connector (receptacle), at the rear panel, using the accessory load cell plug. It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 are shorted, if the distance between the indicator and a load cell is shorter than 5m. The output voltage of a load cell is a very sensitive signal. Place the load cell cable away from any noise source. It is possible to connect four 350 ohm load cells.
3.5. Verifying Load Cell Output and Input Sensitivity The input sensitivity of the indicator is 0.2 µV/division or more. Adapt to the following inequality, when you design a weighing instrument using the indicator and load cell(s). Caution A change in input voltage sensitivity is required to cause a one division change in the display. Select as large an input sensitivity voltage as possible so that the weighing interval becomes stable. Consider the leverage if a lever is used.

5. Calibration The indicator converts an input voltage from a load cell to a "mass" value and displays it. Calibration is the adjustment function so that the scale (indicator) can weigh correctly. 5.1. Items of the Calibration Mode There are four items in the calibration mode. How to enter the calibration mode: In the weighing mode, press the CAL key which is located behind the CAL cover at the lower right of the front panel. After CAL in is displayed for 2 seconds CAL 0 will appear.
CAL Caution Writes all the set data into non-volatile memory and displays CALoFF. Then, press the ON/OFF key to turn the indicator off. Note that the ON/OFF key does not function alone in the calibration mode. When a value is mistakenly set, press the ESC key while holding the ON/OFF key to finish the calibration mode without storing the value. After CAnCEL is displayed, press the ON/OFF key to exit from the calibration mode and turns the indicator off.

Step15 Press the ENTER key after the STABLE mark turns on. Proceed to step 17.
Press and hold the ON/OFF key and press the ESC key. No parameters are changed, CAnCEL is displayed and the calibration mode is finished. Step18 Press the ON/OFF key to turn the display off. 5.3. Weighing Range Function The weighing range function can select "single range" or "dual range". Specify each weighing interval (division) for the multi-interval instrument. Each weighing interval is displayed according to a net value or gross value.
5.3.1. Setting the Division and Range Consider the following rules to design the weighing range. Rule 1 Select the division and range of each weighing range so as to fit the following inequality. The first range < the second range The division of the next weighing range is automatically set larger than the division of the lower weighing range. Rule 2 When setting the dual range, the upper limit value of the second range becomes the maximum capacity. Rule 3 Select a resolution smaller than 40000.
5.5. Gravity Compensation Function If the scale is used at the calibration location, it is not necessary to perform this function. If there is a difference in the gravity acceleration between the calibration location and the installed location, it may cause a weighing error. This function specifies these gravity accelerations and corrects the span error. Note The decimal point is not displayed in the function. Example: 9798 = 9.

Preparation and Specification Set the following parameters to use the accumulation function. Select CF08 1 for the CF-function so that the accumulation function becomes effective. Specify the method of accumulation and data at F20 of the F-function.
9.2. Display and Operation Action of Accumulating Data When accumulating data, the display blinks once. If the accumulated data is stored, the M+ mark is displayed. Caution This function can not accumulate data with a different unit. Specify a unit before use. Display of Accumulated Data When setting to CF08 1 (Effective accumulation function) and pressing the key that allows accumulation display, totAL is displayed and the total data is displayed with the M+ mark blinking.
Output of Accumulated Data The accumulated data can be output to the serial interface. Output by manual or automatic, and output data format is selected at F41 of the F-function setting.
10. Code Memory The AD-4406 has four Code memories (1 through 4). Each Code memory stores a set of setpoints. The data is stored in non-volatile memory, and is not lost even if power is turned off. Memory number 0 is a temporary memory and the data is lost when power is turned off. The active code memory number can be changed by key switch, external control input, or a command via the serial interface.
11. Comparison This function has the "upper / lower limit comparison", the "5-stage (HiHi/Hi/OK/Lo/LoLo) comparison", the "setpoint comparison" and the "simple batch". They compare the weight data with preset parameters and can output the result of the comparison to the display and buzzer, also to the relay-outputs of OP-03, OP-05 and OP-08.
11.1.1. Condition Formula for Comparison Comparison is performed based on the following formula.

Triangle 2 is displayed when Gross ≧ Full regardless of the F24 setting.
Toward the Zero band Preliminary and Free fall output are holding the off state. Over/Under comparison starts. If F23 is set to 30, judgment starts when Free fall turns on. The judgment is not latched and the output is according to the state at the time. The Weighing completion relay is turned on if F24 is set to 2. The on time is set by F25. The READY mark is blinking regardless of the settings of F24 and F25. Start is may be accepted at this state.
12. Hold Function This function displays the hold weight data after averaging the weight data for a specific period. Useful to determine a live animal's weight. Averaging time is selectable up to 9.9 seconds by 0.1 second step. 3 methods are available to start averaging; manual start, automatic start after stable, and manual / automatic start. Manual start is available with key switch or external input.
The key switch will function as the HOLD key if F10 or F11 parameter is set to A. The external input function of averaging start is 19 and hold release is 20 of F13, F14 and F15. The function is accepted at the off to on edge of the external input. Conditions of the Average and Release The method to start/stop the average and to release the hold state depends on the F2 setting.

14. RS-422/RS-485, Relay Output (OP-03) Replacing the RS-232C interface with this option, the RS-422/RS-485 interface can connect up to 32 indicators and control them from a computer or a PLC. The functions of the RS-422/RS-485 interface are common to RS-232C except the signal system. The relays output the result of comparison. Solid-state-relay Maximum voltage 50VDC Maximum current 100 mA DC Maximum resistance 8 Ω Pin connections Function RS-422 RS-485 Relay output Pin No.
Switching Between RS-422/RS-485 Switching between RS-422/RS-485 is made with the slide switch (S1) on the OP-03 board. Connection The polarity of signals A and B may vary with different computers. It is not necessary to ground the SG terminal when using a computer without a signal ground terminal. RS-422 RS-485 Some computers have terminators inside.
15. Relay Output & Control Input (OP-05) Replacing the RS-232C interface with this option, 3-relay outputs and 3-control inputs can be used with the RS-232C interface of this option. RS-232C functions and pin connections are the same as the RS-232C interface described in “13. RS-232C Interface (OP-04, OP-05, OP-08)”. The control inputs can control the indicator from an external terminal just like the front panel key operations. Set the external control functions at F13 - F15 of the F-Functions.
16. 4-20 mA Analog Output (OP-07) The OP-07 analog output option is for sending the weight data to an analog input unit. The output is a 4 mA to 20 mA current output proportional to the display reading. The output data is updated in synchronization with the display update. Specifications Output current Load resistance Resolution Output terminal Accessory 4 mA to 20 mA * Non-linearity Less than +/- 0.1% fs Temperature ZERO Less than +/- 0.02% fs/C 0 to 510 Ω SPAN Less than +/- 0.02% fs/C Approx.
17. Current Loop Output (OP-08) Replacing the RS-232C interface with this option, current loop output, 3-relay outputs and 1-control input can be used with the RS-232C interface of this option. RS-232C functions and pin connections are the same as the RS-232C interface described in “13. RS-232C Interface (OP-04, OP-05, OP-08)”. The control input can control the indicator from an external terminal just like the front panel key operation. Set the external control functions at F15 of the F-Functions.
Current Loop Output The current loop output can be used to output data to an A&D printer and a display unit. The current loop output is of the passive type and requires an external current source of 20 mA current. A&D’s printer and display unit can be connected without an external power source, because they supply the current. The output terminals do not have a polarity. Each output terminal can be connected to either the plus or minus inputs of the peripheral unit.
