CHAPTER 2 SAFETY FEATURES

Introduction This section describes the various safety features that are incorporated into the

printer to provide a safe operating and maintenance environment

Safety Notices Safety notices in the form of PROHIBITION, WARNING, CAUTION and

MAN-DATORY labels are placed on the printing machine and notices are posted throughout the associated documentation to alert the operator/maintainer to possible hazards which may cause physical injury or equipment damage The following label illustrated below, may be fitted to the printer, this signifies that the user should refer to the Safety section of the Operator Manual before attempting to carry out work on the equipment

Prohibition Notices

Prohibition notices draw the attention of users/maintainers to prohibiting behav-iour likely to cause a risk to health or safety The following table displays the prohibition labels affixed to printer and displayed in the machine documentation:

PROHIBITION STRONG MAGNETIC FIELD A STRONG MAGNETIC FIELD EXISTS IN THE VICINITY OF THE CAMERA LINEAR MOTORS THAT MAY ACT UPON FERROUS OBJECTS WHOSE MOVE-MENTS COULD LEAD TO PERSONAL INJURY AND/OR DAM-AGE TO THE MACHINE.

PROHIBITION STRONG MAGNETIC FIELD A STRONG MAGNETIC FIELD EXISTS IN THE VICINITY OF THE CAMERA LINEAR MOTORS THAT REPRESENT A SERIOUS HAZARD TO PEOPLE FITTED WITH METALLIC IMPLANTS.

GENERAL DEK printing machines incorporate safety features that provide a safe operating

environment for the operator and the printer

The design and implementation of safety circuits used in DEK machines conform to:

• BS EN13849-1:2006 part 1 & 2

E Stop The printer is fitted with an emergency stop push button control switch (E Stop)

located within easy reach of the operator Operation of the E Stop initiates suspension of printer operation

Covers The printhead cover is fitted with a cam interlock switch to protect personnel

from internal moving parts

NOTE

1 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.

2 The safety features designed into the printer are for the protection of all operators and maintenance personnel DEK strongly recommend safety devices are never overridden.

There are two machine cover designs as follows:

• Sliding Glass Cover (two variants - type SGC and type iX)

Lid Bolt A lid bolt is fitted to all printers to prevent the front printhead cover from being

raised during the print cycle The iX printers have an extra lid bolt fitted to prevent the rear printhead cover from being raised during printer operation The lid bolts are withdrawn and the printhead cover may be raised:

• When pause or stop is selected during a print cycle

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 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 following diagnostics:

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

The printer is fitted with an emergency stop push button control switch (E Stop) The E Stop switch, once pressed, is a latching switch and requires resetting

To reset the E Stop, turn the button clockwise until it unlatches

Pressing the E Stop or opening the printhead cover cuts the servo axes power supply A warning of this condition is reported on the printer monitor

E Stop Module

Shut Down

If the E Stop loop is opened by pressing the E Stop or opening the printhead cover, an emergency stop is initiated via the E Stop module When actuated the following areas of the printer are rendered inactive:

• Print Carriage Servo (axis stopped before power is removed)

• Paste Cartridge Tilt Up/Tilt Down Pneumatic Actuator

Trang 12

• Rail System Front and Rear Belt Motor Drives

• Rising Table Brake (brake engages when power is cut)

• X Camera Motor (axis stopped before power is removed)

• Y Camera Motor (axis stopped before power is removed)

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.

Apart from the metal covers printers, the safety circuits have been designed to conform to EN954 Category 2 and checks for welded contacts before resetting Additional safety is achieved by duplication of the power contactors to provide redundancy

Recovery When normal working conditions are restored, release the E Stop switch and,

when prompted by a screen message, press the System button.

PRINTHEAD COVER

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

operators and maintenance personnel DEK strongly recommend safety devices are never overridden

Open Cover Opening the printhead cover allows access to the following areas:

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 pause or stop is selected during a print cycle

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
