FUNCTIONAL DESCRIPTION
1. Initially, with the weighing hopper 2 being empty, the AD-4401 displays the zero range at the gross.
2. In this state, open gate G1. When the display on the AD-4401 reaches the Full (optional preliminary) set value,
its output is turned on and closes gate G1. The weighing hopper 2 has now been filled with raw material.
3. Press TARE. The display on the AD-4401 is cleared to 0.
4. Open gates G2 and G3. The display of the AD-4401 is decremented, and when it reaches preliminary
Its output is turned on and closes gate G2.
5. When the display reaches final output is turned on and closes gate G3.
Now, one weighing cycle has completed and the display on the AD-4401 shows the final value, indicating that
receiving bin has been loaded with that weight. Use the setting of overlimit/underlimit to check whether the
weighing value is within limits.
5. When the volume of material left in the weighing Hopper 2 becomes less than Zero band, Zero band
Output signal is turned on.
Note: SQF-21/ SQF-22 setting enables to add automatically FINAL to ZERO BAND or FULL . Therefore there is
always enough ingredient left in the hopper for a measurement.
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.
