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.

CAUTION Turn the source power off.
After checking wiring, fit the terminal cover
in the original state. （TB1 Only）
● Check that screws at the terminal block are tight.
● Check the source voltage, using a multimeter or the like.
Operate the product at voltage fluctuation within ±10% of the rated voltage.
6. Adequate Operation Method
CAUTION Do not touch with wet hands.
To change the setting at the jumper or DIP switch, turn the
power switch off without fail to avoid electric shock.
Do not disassemble or remodel.
Do not insert a socket to jumper J6.
● Do not operate the product at ambient temperatures below -10°C or above +60°C.
