6.1.4 Safety Operating Elements
Safety Concept
The hand-held terminal IndraControl VCH 08.1 contains a dual circuit, 3-stage
enabling switch which is operated by two integrated actuators located on the
rear side of the housing. The enabling switch consists of individual switching
elements and can be used in safety circuits up to category 4 (EN 954-1) if the
evaluation is appropriate. For this, the two circuits have been ndirect coupled
and designed in a redundant manner.
In operating modes with enabling switches one of the actuators of the hand-
held terminal IndraControl VCH 08.1 must be consciously held in the central
