Software notes show the location in the SCD where you
can make the appropriate settings and adjustments. Go to
the menu View, Dialog box of the SCD and activate the
item File cards to view the named dialog fields as required.
Alternatively, the Software Assistant will guide you through the
appropriate setting.
If you use the Allen-Bradley Guardmaster SafeShield function
module, you will find the functions under the same names, however
to some extent in different places in the SCD dialog box. This is
dependent on the scope of the related function. The operating
instructions for the SafeShield function module contain detailed
information.
Sender and Receiver
In drawings and diagrams, the symbol denotes the sender and
the symbol denotes the receiver.
The term “dangerous state”
The dangerous state (standard term) of the machine is always
shown in the drawings and diagrams of this document as the
movement of a machine part. In practical operation, there may be a
number of different dangerous states:
• Machine movements
• Electrical conductors
• Visible or invisible radiation
• A combination of several risks and hazards
Safety
This chapter deals with your own safety and the safety of the
equipment operators.
➢ Please read this chapter carefully before working with the
SafeShield safety light curtain or with the machine protected by
the SafeShield safety light curtain.
Specialist Personnel
The SafeShield safety light curtain must be installed, commissioned
and serviced only by specialist personnel. Specialist personnel are
defined as persons who
• Have undergone the appropriate technical training
and
• Who have been instructed by the responsible machine operator
in the operation of the machine and the current valid safety
guidelines
and
• Who have access to these operating instructions.

Applications of the Device
The SafeShield safety light curtain is an item of electro-sensitive
protective equipment (ESPE). The physical resolution is 14 and 30.
The realizable protective field height is between 300 and 1800mm.
The device is a Type 4 ESPE as defined by IEC 61496-1 and -2 and is
therefore allowed for use with controls in control category 4 in
compliance with EN 954-1. The emergency stop monitoring in the
device corresponds to stop category 0 in accordance with EN 418.
The device is suitable for:
• Hazardous point protection (finger and hand protection)
• Hazardous area protection
• Access protection
Access to the hazardous point must be allowed only through the
protective field. The equipment/system is not allowed to start as
long as personnel are within the hazardous area. Refer to
“Examples of Range of Use” on page 9 for an illustration of the
protection modes.
Depending on the application, mechanical protection devices may
be required in addition to the safety light curtain.
Notes The SafeShield safety light curtain operates as a standalone
system, comprising a sender and receiver, or in
combination with other cascadable SafeShield safety light
curtain systems. This means that the protective field can
be adapted to suit individual safety requirements.
Correct Use
The SafeShield safety light curtain must be used only as defined in
“Applications 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-
also during mounting and installation-any warranty claim against
Allen-Bradley Guardmaster shall become void.
ATTENTION: Only use the safety light
curtain as an indirect protective measure!
An opto-electronic protective device
provides indirect protection, e.g., by
switching off the power at the source of the
hazard. It cannot provide protection from
parts thrown out, nor from emitted
radiation. Transparent objects are not
detected.
