2.2 Special versions
For special versions, which are not listed in the ordering code, these specifications apply accordingly, provided that
they correspond to the standard version.
2.3 Purpose
The non-contact, electronic safety switchgear is designed for application in safety circuits and is used for monitoring
the position and locking of movable safety guards.
F
The safety switchgears are classified according to EN ISO 14119 as type 4 interlocking devices. Designs with individual coding
are classified as highly coded.
The different variants can be used as safety switch with interlocking function either as solenoid interlock.
2
If the risk analysis indicates the use of a
monitored interlock
then a variant with the monitored interlock is to be used,
marked with the
>
symbol in the ordering code.
The actuator monitoring variant (B) is a safety switch with an interlock function for process protection.
The safety function consists of safely switching off the safety outputs when the safety guard is unlocked or opened and
maintaining the safe switched off condition of the safety outputs for as long as the safety guard is open.
2
Interlocks with power to lock principle may only be used in special cases after a thorough evaluation of the accident risk, since
the safety guard can be opened immediately on failure of the power supply or upon activation of the main switch.
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.
