• Intervention in the controls of the machine by electrical means must be possible so as to enable
immediate termination of potentially hazardous states in each working phase.
• The safety clearance between hazard location and protection zone must be
sufficiently large enough such that the potentially hazardous state is terminated before the person
has reached the hazard location (refer to 4.1).
• The mechanical and electrical installation shall be carried out by trained and qualified personnel.
The switching outputs of the COMPACT (OSSD's) shall be connected as two-channel outputs to
the shutoff path for the potentially hazardous condition (refer to 5.1 and 5.2).

Design and Function

3.1

System Overview

The COMPACT equipment consists of transmitter and receiver. The transmitter consists of the con-
trol electronics and a modular arrangement of IR-radiation sources which are sequentially triggered
in quick succession and send out coded infrared pulses. The receiver consists of a control and eval-
uation assembly with the switching outputs and modular IR reception elements which are evaluated
in synchronisation with the transmitter. The synchronisation is realised by optical means. Intercon-
nection of both components by a cable is not necessary. The control assemblies are identical for all
COMPACT models, the IR transmitter and reception modules differ however in their radiation range
and optical characteristics. Each component is housed in a robust aluminium profile casing of stand-
ard design and is powered by 24 V DC.
