Filling sequenceThe Tracker 244 and 225 have 2 relays with volt free contact or 4 TTL outputs respectively. These outputs can be used for alarms or for a batch control filling sequence.
The filling modes can be "Fill", where the container to be filled is on the load cells, or "Loss of weight" where the product's reservoir/tank is on the load cells. Typical Fill Control SequenceThis sequence will detect a new empty container is in position and will fill to 97Kg (Setpoint 1 / Output 1) and then trickle feed to 100Kg (Setpoint 2 / Output 2) to avoid over filling.
* The sequence will be terminated immediately if the cut-off time is exceeded. ** The actual fill weights are stored to calculate the in-flight setpoint ajustments for the next sequence to improve filling accuracy. |
