Original instructions
Specialist Personnel
The GuardShield safety light curtain must be installed, commissioned
and serviced only by a qualified person. A qualified person is defined
as a person who:
• Has undergone the appropriate technical training
and
• Who has been instructed by the responsible machine operator in
the operation of the machine and the currently valid safety
guidelines
and
• Who has read and has ongoing access to these installation
instructions
Range of Uses of the Device
The GuardShield safety light curtain is classified as electro-sensitive
protective equipment (ESPE). The physical resolution is 14 mm (0.55
in.) or 30 mm (1.18 in.). The maximum protective field width is 7 m
(22.9 ft) for the 14 mm (0.55 in.) resolution and 18 m (59 ft) for the 30
mm (1.18 in.) resolution GuardShield. The protective field height is
between 160 mm (6.3 in.) and 1760 mm (69.2 in.).
The GuardShield with an Integrated Laser Alignment system is
offered in protected heights from 320 to 1600 mm in increments of
160 mm. All GuardShield light curtains with ArmorBlock Guard I/O
have Integrated Laser Alignment.
The device is a
Type 4 ESPE as defined by IEC 61496-1 and CLC/TS
61496-2 and is therefore allowed for use with controls in safety
category Type 4 in compliance with EN ISO 13849, SIL CL3 in
accordance with EN62061 or up to PLe in accordance with EN ISO
13849. The device is suitable for:
• Point of operation protection (finger and hand protection)
• Hazardous area protection
• Access protection
Access to the hazardous point must be allowed only through the
protective field. The machine/system is not allowed to start as long as
personnel are within the hazardous area. Refer to the “Examples of
Range of Use” on page 6 for an illustration of the protection modes.
Depending on the application, mechanical protection devices may be
required in addition to the safety light curtain.
Proper Use
The GuardShield safety light curtain must be used only as defined in
the “Range of Uses of the Device.” It must be used only by qualified
personnel and only on the machine where it has been installed and
initialized by qualified personnel.
If the device is used for any other purposes or modified in any way,
warranty claims against Allen-Bradley/Guardmaster shall become null
and void.
