⑧You can adjust the pulse frequency by turning the adjustment trimmer on the side of the main unit.
Use a precision flathead screwdriver to adjust it.
When using supported models: DTY-ELG31-PAU/DTY-ZPA-G31
Toward + (counterclockwise): Frequency increases.
Toward - (clockwise): Frequency decreases.
(Power supply)
· Connect the AC adapter connector to the power cable of the main unit.
Insert the connector covers into each other so no dust gets inside.
Note) Squeeze the lever in a single motion.
A pulse blow may not occur if you squeeze it slowly.
Note) The trimmer increases frequency when turned counterclockwise and decreases when turned clockwise.
The component parts of the trimmer may be damaged if you fully open or fully close it and then turn it further.
Note) Piping conditions may cause variations in frequency characteristics and flow rate characteristics.
Use a Φ6 air tube that is less than 3 m long.
· Connect the ground cable (green wire).
Note) 0V (AC adapter output) and F.G. (frame ground wire) are connected inside the main unit.
Static charge removal performance is reduced when not fully grounded.
· Connect the AC adapter to the power supply (AC 100 V - 240 V, 50/60 Hz).
· When using the relay cable, connect it between the AC adapter connector and the power cable of
the main unit.
Note) The AC adapter cable is not a flex resistant cable.
If there is a risk of the cable moving, then secure the AC adapter cable or the connectors.
The main unit cables and relay cable are flex resistant.
The cable bending radius must be 32 mm or above.
(Air)
· Use clean air, from which oil and moisture have been removed, as the medium.
· Attach the air tube (φ6-mm outer diameter) to the air fitting on the main unit.
(Urethane tube recommended: Urethane tube/nylon tube)
Note)
The air tube length must be 3m or shorter.
· Install a regulator between the air tube and the air source.
· Do not excessively bend or twist the Φ6mm air tube near the fitting. Doing so may result in air
leakage. When using nylon tubes, the minimum bending radius is 30mm.
Replacing the in port/pulse blow unit
