Safety Application Example
Machine Press Infeed Guarding
Perimeter guarding of the material
infeed and rear of a press
Description: The device used for reset of the light screen latch must be located outside
of the guarded area at a location where the entire guarded area can be clearly
seen. The controller is programmed for 1-beam floating blanking to ignore the
infeed material loop. The front opening of the press is guarded using a
Dual MINI-SCREEN system.
Guarding: The infeed area and the rear opening of a high-tonnage press are guarded by
a light screen used with corner mirrors.
Light Screen: Long-range (18 m/60') MINI-SCREEN sensors are used with controller model
MSDINT-1L2, which provides the latching output required for perimeter guarding.
Two model MSM Series corner mirrors are used for guarding two sides of the press
with one pair of sensors. Sensors and mirrors are mounted using four model
This application example depicts only
generalized guarding and should not be automatically treated as a solution for
any particular situation. Every guarding application has a unique set of safety
requirements which must be carefully examined. Extreme care is urged to ensure
that all safety and legal requirements are met and that all installation
instructions are followed.
In addition, any questions regarding safeguarding should be directed to the
factory’s own Safety Department or Safety Officer. No responsibility will be
taken for use of these examples which are only guidelines to the types of
