OVERVIEW
The AU S3M2 control unit is a complete system for control of type 2
electro-sensitive safety equipment (ESPE) in compliance with the European
standard prEN 50100 project for accident prevention on hazardous
machines and plants.
When correctly connected to a safety barrier or to a safety device that
performs the sensing function, the AU S3M2 control unit checks safe
functioning of the sensing device by sending a test signal and assessing its
reply time.
With its integrated intrinsic safety circuit, the AU S3M2 control unit is able
to detect any hardware faults in its internal circuits and also checks correct
functioning of its own output circuit consisting of two guided contact safety
relays.
Correct functioning of external auxiliary relays or contact blocks is also
checked at each test cycle, with also permanent automatic monitoring of
the muting and override function circuits.
If a system malfunction is detected, the AU S3M2 unit promptly de-
energizes its output circuit and switches to fail condition.
Control unit status is output continuously by leds while the self-test output
permits remote management of information regarding correct functioning
of the device.
APPLICATIONSAPPLICATIONS
The AU S3M2 control unit (combined with Argolux AS series light barriers)
can be used effectively in all sectors of industrial automation requiring
control and protection of access points to danger areas.
The device, with its own internal circuit able to assure safe management
of the muting function, is particularly suited for protection of access points
to the load and unload areas of:
• automatic palletizing/depalletizing systems;
• materials handling and storage systems;
• packaging and wrapping machines;
• assembly lines;
• industrial automatic warehouses.
When combined with an Argolux AS light barrier and connected to
specific muting sensors that complete the system for this type of
application, the AU S3M2 control unit provides an efficient solution to the
problem of man/material discrimination at dangerous access points
characterized by transit of pallets.
