1. Outline of Actions
The pulse jet controller conducts sequence control of pulse jet valves of the dust collector
according to the number of valves.
You can designate an arbitrary number of steps between 1 and 10 (1 and 6) according to
the number of connected valves, and indicators show the operating valves.
The ON and OFF time can be designated independently of each other as shown in Fig
1-1.
(Fig. 1-1)
The pulse ON time and pulse OFF time of the second and later steps are the same
as those of the first step.
