GuardShield Safety Light Curtain
Introduction
The GuardShield family of safety light curtains are general purpose
presence sensing devices, designed for use on hazardous machinery
providing point of operation, as well as, perimeter and access
detection.
It is a self-contained, two box, Type 4 ESPE (Electro Sensitive
Protective Equipment) with DIP-switch selectable operating modes.
The GuardShield is offered in a number of configurations based on a
standard Type 4 safety light curtain platform.
In addition to the standard GuardShield, the GuardShield is offered
with a Remote Teach box used to externally teach fixed blanking, in a
cascading configuration which allows the interconnection of up to
three pair of Guard Shields, with an integrated laser alignment system
in standard and cascadable configurations and with connectivity to
ArmorBlock Guard I/O for network connectivity providing OSSDs
over a DeviceNet safety network. The ArmorBlock Guard I/O option
is available in standard and cascadable versions with the integrated
laser system.
Features of the GuardShield, which are integrated into the system’s
receiver;
• Fixed blanking
• Floating blanking
• External device monitoring (EDM)
• Internal or external restart
• Beam coding
• Laser alignment (option)
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. These instructions are an
essential part of the safety precautions and therefore have to be
observed at any time.

These installation instructions are designed to
address the technical personnel of the machine
manufacturer and or the installer of the safety
system regarding the proper mounting,
configuration, electrical installation,
commissioning, operation and maintenance of
the GuardShield safety light curtain.
These installation instructions do not provide

ATTENTION
ATTENTION
Potentially hazardous situation, which, if not
prevented, might lead to serious or deadly
injury.
Failure to observe may result in dangerous
operation.
ATTENTION
The GuardShield must not be used with
machines that cannot be stopped electrically in
an emergency.
The safety distance between the GuardShield
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 has to be installed in a way that operators can
only operate within the sensing area.
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 to flammable or explosive gases.
Regular safety inspections are imperative (see maintenance).
Do not repair or modify the GuardShield. The GuardShield safety
light curtain is not field repairable and can only be repaired at
the factory. Removal of either of the GuardShield endcaps will
void the warranty terms of this product.
