WARNING
COMPRESSED AIR. COMPRESSED AIR SHOULD NEVER IMPINGE UPON THE
BODY. PORTS, PIPES, ETC MUST NEVER BE BLOCKED BY HAND. BEFORE
CONNECTING OR DISCONNECTING ANY PNEUMATIC COMPONENTS, ENSURE
THE COMPRESSED AIR SUPPLY HAS BEEN DISSIPATED AND DISCONNECTED
FROM THE MACHINE.
The mains air supply to the DEK printer should be between 5 bar and 8 bar.
The air should be to quality class 2.3.3, where:
2 (dirt) = 1 micron or less
3 (water) = -20°C pressure dew point
3 (oil) = 1mg/m3 or less
The mains air supply is filtered and regulated to 0.5MPa (5 bar) before being
sensed by the air pressure switch, which is set at 0.3MPa (3 bar) The com-
pressed air input is applied to the following:
• Printer Rear Solenoids
• Print Carriage Solenoids
• High Throughput Conveyors (HTC)
• Vacuum Tooling
• Grid-Lok Tooling
• Air Ionizer
The electrically activated solenoid valves provide pneumatic power through
several types of air cylinder.
Printer Rear
Solenoids
The number of solenoids varies from printer to printer depending on which
options are fitted to the printer. The solenoids are labelled with the solenoid
number for identification.
