The safety function consists of safely switching off the safety outputs when the safety guard is opened and
maintaining the safe switched off condition of the safety outputs for as long as the safety guard is open.
F
The safety switchgears are classified according to ISO 14119 as type 4 interlocking devices. Designs with individual coding are classified
as highly coded.
Safety sensors and actuators with latching (ordering suffix 'R') always must be used in pairs. The latching force
(approx. 18 N) exercised by the permanent magnet keeps hatches and small guards closed, also in a de-energised
condition.
The system can be used as a door end stop up to 5 kg at 0.25 m/s.
The diagnostic output of the safety sensor alternatively can be used as a conventional output or as a "serial output"
with input and output channel.
Series-wiring
Series-wiring can be set up. In the case of a series connection, the risk time remains unchanged and the reaction
time increases by the sum of the reaction time of the inputs per additional unit specified in the technical data. The
quantity of devices is only limited by the cable drops and the external cable fuse protection, according to the
technical data. Up to 31 device variants with serial diagnostics can be wired in series.
The user must evaluate and design the safety chain in accordance with the relevant standards and the required safety
2
level. If multiple safety sensors are involved in the same safety function, the PFH values of the individual components must
be added.
The entire concept of the control system, in which the safety component is integrated, must be validated to the relevant
2
standards.
2.4 Warning about misuse
In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant
2
components cannot be excluded. There are no residual risks, provided that the safety instructions as well as the
instructions regarding mounting, commissioning, operation and maintenance are observed.
2.5 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from defective mounting or failure to comply
with the operating instructions manual. The manufacturer shall accept no liability for damages resulting from the
use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary repairs, conversions and modifications to the
device are strictly forbidden, the manufacturer shall accept no liability for damages resulting from such invasive
work, arbitrary repairs, conversions and/or modifications to the device.
