Not all component variants, which are possible according to this order
code, are available.
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefore
the compliance with the Machinery Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The electromechanical enabling switches of the ZSD series are for
instance used on industrial robots and automated production systems
to activate the control functions for hazardous situations through other
control devices.
An enabling device is an additional manually-operated control device,
which is used in conjunction with the start equipment and enables a
machine function, when it is continuously actuated.
The redundant contact configuration enable signal evaluation with
common safety relay modules. The contact configuration enables the
signal processing according to EN 954-1 PL e (level 2 ↔ 3) or
PL c (level 2 ↔ 1).
