Normal Batching Of The Customer Programmed Control Mode 62 7.4.2. Loss-In-Weigh Of The Customer Programmed Control Mode - AND Multi Function Weighing Indicator AD-4402 Instruction Manual

7.4.2. 7.4.2. 7.4.2. 7.4.2. Loss Loss Loss Loss- - - - in in in in- - - - weigh of the C
C C C C ontrol
This function outputs gate control signals that are derived from the compared setpoint
and weighing data of the materials from the hopper.
When the weight decreases past the setpoint, the gate control signal turns off.
When the weight increases past the setpoint, the gate control signal turns on.
The weighing mode in this function is bi-directional. Therefore, the comparison is
repeatable (reversible).
Concerning Parameters of the Function
Using loss-in-weigh of the comparison function
[5qf- 1] [1]
[5qf- 3] [1]
Using the external control switch for normal batch and loss-in-weigh.
[5qf- 3] [2]
Checking whether there are remains from the last weighing operation in the hopper.
[5qf-55]
Using the external switch
[1n f-nn] [9]
Checking whether there are remains from the last weighing operation in the hopper.
[5qf-56]
Changing the accuracy of the comparison
[5qf-48]
Using manual compensation
[1n f-nn] [10]

External exchange
If the external switch is used, connect it to the I/O terminals. This
mode can use three gates.

Add final value and zero band
When the remains reach a weight that is under the final value +
zero band, the zero band signal is output.

Add final value and full value
When the final value + full value is less than the remains (gross) in
the hopper, the full signal is output.
