Installation and Precautions

Installation and PrecautionsInstallation and Precautions

3.1.1. Installation and Precautions

The weighing indicator is a precision electronic instrument. Handle it carefully.

The operating temperature is -10°C to +40°C (14°F to 104°F).

Do not install the scale in direct sunlight.

Mis-operation or other problems may be caused by an unstable power source including

momentary power failure or instantaneous noise. Use a stable power source. Do not connect the power cord before the installation has been completed. Verify that the local voltage and receptacle type are correct for your scale. Use shielded cable for all connections. Connect the cable shields to the shield

terminal or case as an earth terminal. Earth ground the indicator. Do not join the earth ground line with other electrical

power equipment. (

Example: There is an earth ground terminal at the power cord receptacle.

Do not install the indicator in a place where it is apt to be charged with static

electricity, or where the relative humidity is lower than 45%RH. Plastic and insulating

materials are apt to be charged with static electricity.

3.1.2. The Load Cell Connections

Connect the load cell cable to the terminal as shown below. 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. Space the load cell cable

away from any noise source. It is possible to connect eight 350ohm load cells.

The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current

120mA.

3. Installation and Precaution

AD-4407 Weighing Indicator Page 5

3.1.3. Adjustment of the Load Cell Output

Caution Use a metal film resistor in the range of 50kohm to 500kohm with a

good temperature coefficient, when adding a resistor to adjust a load

cell output. Use as large of a resistance value as possible in the range

in which the zero adjustment is possible. Solder this resistor at a point

near the load cell or the indicator.

In Case of Reducing the Output Voltage

When the zero output is too large, add a resistor

between EXC+ and SIG-.

In Case of Adding an Offset Voltage to the Output

When the zero output is too small, add a resistor

between EXC+ and SIG+.

Loadcell

Additional resistance

3.1.4. Verifying Load Cell Output and Input Sensitivity

The input sensitivity of the indicator is 0.25mV /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 of 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.

3.1.5. Installing an Option board

Caution Do not remove any screws without the following step.

This is the procedure for the data output board (OP-03, OP-05, OP-07 and OP-08). Step 1 Remove the power cord from the AC power source. Step 2 Remove eight hex bolts (one of them is the sealing bolt) from the rear panel. Step 3 Remove the rear panel carefully as there are cables between the front unit and the

rear panel.

Step 4 Place the option board on the option board space in the rear panel and secure it

with screws.

Step 5 Connect the option cable(s) between the option board and the main board in the

front unit.

Step 7 Connect the interface cable to the option board connector or terminal block. Step 8 Place the rear panel on the front unit, and secure using the bolts removed in Step 2. Step 9 After powered on, enter the F-functions and store the F30's parameters. For OP-03, OP-05 and OP-08, there are parameters in “serial”.

For OP-07, there are parameters in “analog”.

This indicator, converts an input voltage from a load cell to the "mass" value, and

displays it. Calibration is the adjustment function so that the scale (indicator) can display the weight correctly.

Calibration

CalibrationCalibration

5.1.1. Items of Calibration Mode

There are four items in the calibration function in the procedure. How to calibrate: In weighing mode, press the CAL key. After Cal in is displayed

for 2 seconds Cal 0 will appear. Then the required items should be selected and displayed with the MODE key, then executed by pressing ENTER key.

NOTE:

Calibration could be started by simultaneously pressing the ZERO and TARE key,

instead of CAL key. However, in some cases, the procedures are altered to nullify this option. Furthermore, this option is not available with Stamping type version setting.

Specified parameters: First range Range = 50.00kg, division 0.02kg Second range Range = 100.00kg (maximum capacity), division 0.1kg Display 0kg to 50kg : The first range, division 0.02kg. 50kg to 100kg : The second range, division 0.1kg.

Division = 0.02kg

Division = 0.1kg

5.3.1. Selecting 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. And the division can change.

Rule 2 When specifying the dual range, the upper limit value of the second range

becomes the maximum capacity.

Rule 3 Select a resolution smaller than 40000. The resolution is a value that divides the

maximum capacity by the minimum division of the first range.

Even if the zero and span calibration have been completed, there may still

remain a linearity deviation caused by the performance of the weighing unit. The

digital linearization function can rectify or reduce the linearity deviation using weighing points during the zero and capacity. Up to three weighing points can be specified.

Caution This function does not improve repeatability or hysteresis. Use the mass on the condition that lnr 1

Do not press the ENTER key while the STABLE mark is off.

Step 1 Check the Cal 0 display. Press the MODE key to display lnr 0 . Step 2 Enter zero point. Refer to “5.2.3. Zero Calibration”. Step 3 The value of the middle point is displayed after indicating lnr x. x is 1, 2 or 3. The triangle mark of the same number(x) is displayed along with the value. Step 4 Select a middle point.

Select a middle point value using the 0 - 9 keys. Proceed to step 5. Step 5 Place a mass equivalent to the displayed value on the weighing unit. Press the

If you want to cancel the current procedure, press the ESC key to finish this

function. Proceed to step 7 and other points are cleared (canceled).

Step 6 If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each.

If you finish this function, proceed to step 7.

Step 7 Perform step 11 of "5.2.4. Span Calibration" immediately.
