3.12.1 Protective system
Attention !
If there is a collision, the bar may cause serious injuries.
The high level of kinetic energy of the drive results in a braking distance which cannot
be ignored.
Light barriers and safety cut-offs are no guarantee against injuries.
The protective system is made up of protective trip switches and light barriers on the
ends of the bar.
Protective trip switches and light barriers are part of a self-monitoring safety
shutdown system.
If protective trip switches or light barriers cause an obstruction then the following
protective measures are introduced:
– An emergency stop halts all movements
– The operating status STOPPED is activated
– An error message is displayed
Protective trip switches
Protective trip switches trigger the safety shut-down if they are touched by an
obstruction. They are used as hand protection.
Light barrier options
The working area is monitored by light barriers on the front and rear side of the beam.
Important !
The light barriers are active in all operating states.
3.12.2 Panel
