Jog Buttons The two button control switches or jog buttons 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 printer 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

movement of the following diagnostics:

• Print Carriage

• Squeegee Assembly

• Camera Axes

• Rail System

• Stencil Alignment

• Rising Table

• ProFlow

• Paste Dispenser

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.

PRINTHEAD COVER

1.16 Installation Manual Chapter Issue 15, Nov 19

PRINTHEAD COVER

Safety Interlocks The safety features designed into the printer are for the protection of all

operators and maintenance personnel. ASM strongly recommend safety

devices are never overridden.

Opening the printhead cover allows access to the following areas:

• Printhead

• Paste Dispenser

• Squeegee/ProFlow

• Stencil/Screen

• Under Screen Cleaner

• Tooling

The printhead cover is accessible to the operator and an interlock safety switch

protects personnel from the mechanisms during normal line operations. Lifting

the cover cuts power to all motors and selected actuators, via the E Stop

module, to all printer modules.

Full details of the device types fitted can be found in the covers chapter of this

manual.

NOTE

The pass through lane belt motors on the dual lane printer continue running

when the printhead cover is open but stop when the E Stop is pressed.

Pneumatically operated lid bolt(s) prevents the cover being raised during the

print cycle. The lid bolt is withdrawn and the cover may be raised:

• When Open Cover is requested by software

• When pause or stop is selected during a print cycle

• When the E Stop is pressed

Recovery When the printhead cover is closed, normal working condition is restored and

the line may be restarted. Pressing the system button enables resumption of

operations, where this is allowed by the control system.
