CHAPTER 2 SAFETY FEATURES
MACHINE SAFETY FEATURES
Introduction This chapter describes the various safety features that are incorporated into the
machine to provide a safe operating and maintenance environment, the Elec-
trostatic Discharge (ESD) precautions to be taken during SSD handling and the
Electromagnetic Compatibility (EMC) standards that are designed into the
machine.
Warning and
Caution Notices
Black-on-Yellow WARNING, CAUTION and DANGER labels are placed on the
printing machine and notices are posted throughout the associated documen-
tation to alert the operator/maintainer to possible hazards which may cause
physical injury or equipment damage.
WARNING notices draw the attention of operators/maintainers to possible
general or functional hazards which may cause loss of life, serious injury or ill
health. These hazards are either inherent in the machine or arise during the
operation/implementation of procedures.
CAUTION notices alert personnel to the possibility of damage occurring to the
machine material which is likely to arise following the departure from laid-down
procedures. A caution notice does not imply danger to personnel.
An example of the format for each notice is shown below :
CAUTION
ANTI-STATIC HANDLING.
Standard precautions must be adhered to when
handling electronic cards and configuring and inserting into the enclo-
sures.
WARNING
LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.
ENSURE ALL ELECTRONIC COVERS AND MAIN MACHINE COVERS ARE
FITTED BEFORE OPERATING THIS EQUIPMENT.
General DEK printing machines incorporate safety features that provide a safe operating
environment for the operator and the machine.
E Stops The machine is fitted with two emergency shutdown press-buttons (E Stops),
one located on the front right of the machine and one located on the left side
above the rails. Operation of either E Stop initiates suspension of machine
operation.
Covers The front printhead cover is fitted with a cam safety switch to protect personnel
from moving equipment.
A metal side safety cover is fitted to the machine side to protect personnel from
inadvertent access to the machine around the board entry/exit area.

PRINTHEAD COVER
2.2 Installation Manual Chapter Issue 1 Oct 02
PRINTHEAD COVER
Access to the machine printhead, stencil and optional under screen cleaner is
achieved by raising the printhead cover at the front of the machine.
The front printhead cover is fitted with a cam safety switch to protect personnel
from moving mechanisms during normal operations, opening the cover cuts
power to all motors and selected actuators, via the PNOZ system safety relay
module, to all machine modules.
A metal side safety cover is fitted to the machine side to protect personnel from
inadvertent access to the machine around the board entry/exit area.
Recovery When the cover is closed, normal working condition is restored and the machine
may be restarted. Pressing one of the two machine system buttons enables
resumption of operations, where this is allowed by the control system.

EMERGENCY SHUTDOWN
Chapter Issue 1 Oct 02 Installation Manual 2.3
EMERGENCY SHUTDOWN
The machine is fitted with two emergency stop push button control switches
(one at the front right corner of the machine and one on the left side of the
machine above the rails). Pressing either of these push-buttons (or opening the
machine access covers) cuts the power supply to all motors and selected
actuators. A warning of this condition is reported on the machine monitor.
