START of dosing:
Dosing can be started either by triggering the "START" softkey or by applying a
high pulse to the control input.
After the START function has been triggered, the dosing output is switched to
active (High) and the dosing counter is counted down in the standard direction
when flow is present.
If the dosing process is stopped incompletely by hand, it can be restarted by the
START function.
STOP of dosing
If the dosing process is started, it can be stopped or interrupted by the STOP
function. Resumption of dosing to reach the total dosing quantity is possible by
START.
Like the START function, the STOP function can be remotely controlled by the
control input.
RESETTING the dosing value
If the dosing process is finished or stopped, the dosing quantity can be reset to
the default value by the function RESET.
This function can also be triggered at the control input.
