Fig 8-1 Time Sequence of Catchweigher in Self-control Mode
Brief introduction of control procedure of batching scale in self-control mode (Please refer to
the sequence order figure):
(1) The instrument starts to run and it will judge whether the weight is higher than zero zone. If it
is higher, then enter t0 delay to wait for the cargo to be completely loaded to the weighing
platform;
(2) Time t0 is over and the instrument will start to calculate the average weight of cargo with time
interval of t1. The value calculated will be the reference for batching scale signal;
(3) Time t1 is over and the instrument will enter the t2 delay to wait for the cargo to leave the
weighing platform;
(4) Time t2 is over and the instrument will send the sorted channel signal to make the cargo enter
the corresponding channel;
(5) Sending signal is finished and the instrument will judge whether the weight is back to the zero
zone again. Only when the zero zone is entered, would the next cycle be started.
Table 6-2 describes the working process of batching scale in self-control mode in forms of
the program step.
