SAFETY FEATURES
3.1 OVERVIEW
The printer incorporates various safety features that provide a safe operating environment for the
operators/maintainers using:
●
Safety interlocks ensure that potentially hazardous machine operations can only be performed
when the machine is in a safe condition
●
Safety labels to inform the user of areas where danger or residual danger may exist
All safety circuits have been designed to meet the safety requirements as outlined in the machines’
CE Declaration of Conformity. The circuits check for welded contacts before resetting. Additional
safety is achieved by duplication of the power contactors to provide redundancy.
3.1.1 Mains Supply
Where incoming hazardous supply voltages are present, protection is afforded by controlling
access to the enclosures that house the supply. The enclosures require tools to gain access to the
inside and must only be opened by suitably qualified personnel.
The mains isolator switch disconnects the facility mains supply to the power supply enclosure.
Mains supply still exists in the printer, up to the mains isolator switch.
Hazard warning labels are placed on the outside of enclosures where dangerous voltage
(100V-240V a.c 50-60Hz) terminations are present within.
3.1.2 Safety Notices
Safety notices in the form of PROHIBITION, WARNING, CAUTION and MANDATORY 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 relevant section of the Technical Reference Manual before attempting to carry out work
on the equipment.
3.1.2.1 Prohibition Notices
Prohibition notices draw the attention of users/maintainers to prohibiting behaviour likely to cause a
risk to health or safety. The following table displays the prohibition labels affixed to printer and dis-
played in the machine documentation.
