FUNCTIONAL DESCRIPTION
1. First, press TARE to clear the display on the AD-4401 to zero.
2. Open gates G1 (full flow), G2 (medium flow), and G3 (dribble flow). The display on the AD-4401 is
incremented, and when it reaches optional preliminary its output is turned on and closes gate G1.
3. When the display reaches preliminary its output is turned on and closes gate G2.
4. When the display reaches final its output is turned on and closes gate G3. Now, one weighing cycle is
completed and the AD-4401 display shows the final value, indicating that hopper 2 has been loaded with that
weight. Use the overlimit/underlimit setting to check whether the weighing value is within limits.
5. When you open gate G4 to discharge into a container, you can use the setting of the zero range to make sure
that the raw material has been completely discharged. However, the AD-4401 cannot control the discharge gate
G4.
When an output condition is established, a relevant
output terminal is turned on (power continuity with
output COM).
An output terminal number can be selected with the
general functions, OUTF-01 through OUTF-08.
A setpoint signal output is turned off unconditionally
when the operation mode is other than the normal
mode.
For the connection of the thumbwheel switch
(16-digit mode) for the setpoints, see 7-4.
