Example of use: Chemical dosing in a production line system
When the buffer is ON:
Every time the external pulse signal is inputted, the programmed flow volume per pulse is accumulated (max
65535 pulses) even when the pump is activated for the earlier pulse input.
*The control stops immediately and all the pulse accumulation is cleared when the key is pushed once.
Pulse input by the key:
Instead of the pulse signal input, pushing the key can start or stop the batch control. In this case, the pump
behaves as the control with the buffer OFF even when the buffer is set to ON in the batch control mode.
