Safety Precautions
Principles for Safe Use and Symbols Used
The following instructions are preventive warnings to ensure the
safe and proper operation of the GuardShield Micro 400 light
curtains. These instructions are an essential part of the safety
precautions and therefore have to be observed at any time.
Throughout this manual we use the labels ATTENTION and
IMPORTANT to alert you to the following:
ATTENTION helps you
• Identify a hazard
• Avoid a hazard
• Recognize the consequences
IMPORTANT: Identifies information that is especially important
for successful application and understanding of the product.
Specialist Personnel
The GuardShield Micro 400 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 Micro 400 safety light curtain is classified as
electro-sensitive protective equipment (ESPE). It fulfills the
requirements of a Type 4 ESPE 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.
These devices are suitable for:
• Point of operation protection (finger and hand protection)
• Hazardous area 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.
ATTENTION
Identifies information about practices or
circumstances that can lead to personal
injury or death, property damage, or
economic loss. Attentions help you identify a
hazard, avoid a hazard, and recognize the
consequences.
IMPORTANT
Identifies information that is critical for
successful appilcation and understanding of
the product.
ATTENTION The GuardShield Micro 400 must not be used
with machines that cannot be stopped
electrically in an emergency.
The safety distance between the GuardShield
Micro 400 and a dangerous machine
movement has to be maintained at all times.
Additional mechanical protective devices
have to be installed in a way that hazardous
machine elements cannot be reached without
passing through the protective field.
The GuardShield Micro 400 has to be installed
in a way that operators can only access the
hazard through the sensing field of the Micro
400.
Improper installation can result in serious
injury.
Never connect the outputs to +24V DC. If the
outputs are connected to +24V DC, they are in
ON-state and cannot stop hazardous spots at
the machine/application.
Never expose the GuardShield Micro 400 to
flammable or explosive gases.
Regular safety inspections are imperative (see
maintenance).
