Connection of the pneumatic actuator

DANGER

Intended use

Operation of the product with gases other than those specified or outside the limits may result in dangerous reactions in the system. Incorrect use poses considerable risks to operating personnel and the environment!

1. Only use the product for gases for which it was designed.
2. Only use the product in the specified limit values for pressure and withdrawal quantity.
3. Usage for another type of gas or outside the limit values is prohibited and constitutes misuse.

WARNING

Noise emission

When working on pressurised pneumatic supply, significant noise emission can occur. Acute and chronic loss of hearing may result.

1. Never perform work on the pressurised pneumatic supply without hearing protection.
2. Only replace the silencers when the supply is unpressurised.

WARNING

Cross-contamination

Cross-contamination of the control air with process gases can result in the control unit being damaged.

1. Ensure that cross-contamination of the control air line is prevented.

WARNING

Displacement of atmospheric oxygen

In the event of inert gas leaks, displacement of atmospheric oxygen may occur. Danger of suffocation!

1. The operator must ensure adequate ventilation and airing in all rooms with gas installations and monitor the oxygen content.

The controller is connected to the M12x1 connection via a 4-pole Namur cable:

The solenoid valves require a supply of clean dry air or nitrogen filtered to 10μm, at 5.6 bar. This is connected via a 8 mm push-in fitting on the base of the device as indicated on the label. Any waste gas from the solenoid valves is vented internally and excess pressure build-up is vented to atmosphere via an IP65 breather on the base of the unit.

Introducing compressed air through A means that the ball valve rotates anti-clockwise and the gas supply is provided from the left-hand side:

Introducing compressed air through B means that the ball valve rotates clockwise and the gas supply is provided from the right-hand side:
