Two Button
Control Switches
The two button control switches or jog switches are positioned such as to
maintain maximum safety for the operator whilst solvent priming or paper
feeding with the printhead cover open. This requires both buttons to be
depressed simultaneously for the function to become active. The use of these
buttons is dependent on the function selected on the machine monitor. During
normal operation these buttons control paper feed and solvent prime opera-
tions. When in maintenance mode, the two button control switches control the
following diagnostics:
• Print Carriage
• Squeegee Assembly
• Camera Axes
• Rail System
• Screen Alignment
• Rising Table
Only one button is required to drive the selected mechanism, the two buttons
are used to drive the mechanism in opposite directions, ie jog forward or jog
back.
Emergency
Shutdown
If an emergency stop is initiated via the EMO, all power and pneumatics to the
machine are removed. Electrical power remains to the M39 EMO enclosure via
the mains isolator but is removed from there to the M37 power supply unit.
Switching mains isolator to OFF removes electrical power from the M39 EMO
enclosure. Pneumatic supply is also closed off and any pressurised air remain-
ing within the machine’s system is vented via the pneumatic dump valve.
