FEATURES

2.1 - Batching
To access batching features, the controller's Mode must be set to Batch (see 6.2F).
It is then possible to perform the following functions from the
input pins:
Batch This function is used to display the live weight of the system but take
regular 'batches' of product without continually changing the setpoint.
When the Batch function is activated the display will tare and SP 1 and
SP 2 will turn on.
Resets the batch value to zero and halts any current batching operations.
Batch Reset
Batch Pause Pauses the batching process and holds the current batched weight on
the display.
Batch Resume Resumes the batching process after it has been paused, or if power was
lost during a previous batch.
See 6.2H–K and Appendix A for instructions on setting up and operating these features.
2.1A - Gain in Weight (GIW) Batching Direction
The Batching Direction parameter is set in 6.2G, and should be set to GIW (Gain
in Weight) for applications where the weight increases as product is added to the
weighing system.
E.g. Setting a setpoint value of 50Kg for SP 1 and 45Kg for SP 2 and enabling GIW batching will al-
low the user to fill a container to 50Kg, with a potential speed change at 45Kg. (See 2.1C for an
alternative method of setting up SP 2.)
The cycle is initiated when the Batch function is triggered. The display will tare, and when 45Kg
net weight is shown, SP 2 will drop out. As product continues to feed, at 50Kg SP 1 will drop
out, halting the fill.
If Flash Gross is enabled (see 6.2L) the gross weight will be displayed (E.g. Now 1050Kg, if the
starting gross weight was 1000Kg). The user can then trigger the Batch function again to call
another 50Kg batch.
2.1B - Loss in Weight (LIW) Batching Direction
The Batching Direction parameter is set in 6.2G, and should be set to LIW (Loss in
Weight) for applications where the weight decreases as product is removed from the
weighing system.
