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.

3. Fixing Method

CAUTION : Install the product free from dust and water splashes.

Round holes (at four places: a) are provided for the pulse jet controller as shown in Fig.

3-1. Use M4 screws to fix securely. Use accessory spacers when necessary.

(Fig. 3-1)

4. Wiring Method

CAUTION : Be sure to turn the source power off when conducting.

①Terminal block (for TB4) cable

Use 0.75mm2to 2mm2vinyl sheath cable.

②Termination method

Install a crimp terminal at the terminal of the AC input and valve output (TB1 and TB2)

cables.

Applicable crimp terminal (example)

●The applicable cable varies

according to the crimp

terminal.
