table
table used to support the work-piece at the machine which may comprise an assembly of rollers, belts or other
fixed or moving mechanical elements
3.2.3
cutterblock
machine component designed to hold the cutting knives or cutting blades

3.2.18
safety related part of a control system (SRP(CS))
part or subpart(s) of a control system that responds to input signals and generates safety-related output
signals.
NOTE The combined safety-related parts of a control system start at the point where the safety-related signals are
initiated (including e.g. the actuating cam and the roller of the position switch) and end at the output of the power control
elements (including e.g. the main contacts of the contactor). This also includes monitoring systems (3.1 of EN ISO 13849-
