practical operation, there can be a number of different dangerous states:
• Machine movements
• Vehicle movements
• Electrical conductors
• Visible or invisible radiation
• Combination of several risks and hazards

OSSD Output signal switching device. The OSSD output is the switching output on
the SafeZone Mini device that is used to stop the dangerous movement. This
output is a semiconductor output and is periodically tested for correct
function. The SafeZone Mini device has two OSSD outputs that operate in
parallel; for safety reasons these outputs must be evaluated using two channels.
