CHAPTER 24 PNEUMATIC MODULE
MODULE OVERVIEW
System
Description
The mains air supply (at a minimum of 5 bar) is filtered and regulated to 5 bar
before being sensed by the air pressure switch, which is set at 3 bar. The
compressed air input is applied to the manifold assembly. The 8 port manifold
has an electrically activated solenoid in each active port, which provides
pneumatic power through several types of air cylinder. Any unused manifold
ports are blanked off.
Air Quality The air should be to quality class 2.3.3, where:
2 (dirt) = 1 micron
3 (water) = -20°C pressure dewpoint
3 (oil) = 1mg/m3
Air Pressure Air should be supplied to the machine at a pressure between 5 bar and 8 bar.
WARNING
COMPRESSED AIR. COMPRESSED AIR SHOULD NEVER IMPINGE UPON THE
BODY. PORTS, PIPES, ETC MUST NEVER BE BLOCKED BY HAND. BEFORE
CONNECTING ANY PNEUMATIC EQUIPMENT TO A COMPRESSED AIR SUPPLY,
ALL MOUNTINGS, FITTINGS, PIPEWORK AND ELECTRICAL CONNECTIONS
SHOULD BE REMOVED FOR SAFETY. NO PIPEWORK ALTERATIONS OR
REMOVAL OF FITTINGS SHOULD BE ATTEMPTED WITH AIR SUPPLIES
CONNECTED.
