SETPOINT: Sets the setpoint values for batch weighing and check weighing.
ZERO: Sets the gross value to zero when the weight value is within the zero
setting range. (Default zero setting range: 2% of maximum capacity)
TA RE : Saves the current gross value as tare and sets the net value to zero.
NET/GROSS: Selects the weight value display method, gross or net.
Function: No function is assigned in the default setting.
ENTER: Does not function alone.
ON/OFF: Turns the display on or off.

1. SAFETY PRECAUTIONS
Read the following precautions carefully before using the indicator.
[Precautions for designing]
WARNING
● Provide an external safety circuit to the indicator so that the safety of the whole system
can be secured even if errors occur in the external power supply or in the indicator.
[Precautions for installation]
WARNING
● Do not use the indicator in the following environments:
- where the temperature and the humidity exceed the specifications
- where corrosive gases or flammable gases exist
- where the indicator gets wet with oil, chemicals or water
Please note that securing the indicator to the control panel will provide the
indicator outside of the control panel with IP65 protection.
● When installing or removing the indicator, be sure to turn off all used external
power supplies beforehand.
[Precautions for wiring]
WARNING
● When wiring the indicator, be sure to turn off all used external power supplies
beforehand.
● When wiring is complete, be sure to attach the terminal block cover provided
with the indicator.
● Be sure to earth ground the indicator.
CAUTION
● Do not clamp control wires or communication cables with power lines or place
them close to power lines.
● Place the load cell cable sufficiently away from high frequency circuits such as
high voltage power lines and inverter load circuits.

6.2. Calibration Using Calibration Weights
Press the CAL key in the normal mode.
When “
Cal" is displayed, press the ENTER key.
When “
Cal 5et” is displayed, press the ENTER
key.
Zero calibration
Press the ENTER key when the STABLE (MD)
status is turned OFF.
When the Function key is pressed, the AD-4401A
proceeds to span calibration without performing
zero calibration.
Dashes are displayed in the sub-display and zero
calibration is performed.
Span calibration
Set the calibration weight value in the sub-display.
Press the ENTER key when the STABLE (MD)
status is turned OFF.
Dashes are displayed in the sub-display and span
calibration is performed.
Press the ON/OFF key twice to return to the normal
mode.
7. FUNCTIONS
When the AD-4401A is powered ON, all the segments of the display turn ON and OFF
to check the display. Then the AD-4401A enters the normal mode and starts weighing.
If the AD-4401A is powered OFF during the OFF mode (with the display OFF),
the AD-4401A will be in the OFF mode when powered ON.
7.1. Control I/O
The applicable connector is an FCN-360 series 16-pin female connector
manufactured by Fujitsu Component Limited or the equivalent. An FCN-361J016
(connector) and an FCN-360C016 (cover) are provided with the indicator.
