Loss-in Weight of Comparison Function | A&D PD4000243 guide

7.4.2.Loss-in Weight of Comparison Function

The function outputs the gate control signals that are compared setpoint and weighing data that is discharged materials from hopper.

When the weight decreases above the setpoint, the gate control signal turns off. When the weight increases under the setpoint, the gate control signal turns on.

There is not direction for the weighing sequence in this function. Therefore, the comparison is repeatable (reversible).

Concerning Parameters of the Function

Using the loss-in weight of comparison function

[5qf- 1] [1] Constomer programmed control [5qf- 3] [1] Loss-in weight

[Function] - [Function setting] - [Sequence] - [Basic]

Using the external control switch for normal batch and loss-in weight.

[5qf- 3] [2] External exchange

If the external switch is used, connect to the I/O terminal. This mode can use three gates.

[Function] - [Function setting] - [Sequence] - [Basic]

Checking the remains of the hopper whether is there the weight of the last operation.

[5qf-55]Add final value and zero band

When the remains reach under the final value + zero band, the zero band signal is output.

[Function] - [Function setting] - [Sequence] - [Setpoint (Compared value)]

Using the external switch

[1n f-nn] [9] Supply swicth control

nn: terminal number of the I/O.

[Function] - [Function setting] - [Control I/O] - [Input]

Checking the remains of the hopper whether is there the weight of the last operation.

[5qf-56]Add final value and full value

When the final value + full filling value is negative, the full filling signal is output.

[Function] - [Function setting] - [Sequence] - [Setpoint (Compared value)]

Changing the accuracy of the comparison

[5qf-48]Average time at criteria

The average time of batch finish output is set. The output of batch finish delays by the average time.

[Function] - [Function setting] - [Sequence] - [Timer]

Using the manual compensation

[1n f-nn] [10] Manual free fall compensation [05 f-nn] [10] Manual free fall compensation

nn: terminal number of the I/O.

The input to control free fall by the external PLC. [Function] - [Function setting] - [Control I/O Function] - [Input]
