6.4.4.5 Machine safety
DANGER
– The reader is fitted on the wall. This variant is visible on the outside and
makes it easier for users to place their identification medium onto the
reader. The read range is better compared to a reader fitted inside the
housing. If the reader is installed outdoors, protection against the
weather, vandalism and sabotage can be assured with the protective
housing (SREL2.COVER1).
A master identification medium can be created for emergencies. This can
be used to open several or all boxes at the same time.
The controller can be powered either via an external power supply unit or
via the network line. The controller, in turn, can power the reader. If the
voltage drop is too great, the reader can also be supplied by an external
power supply unit (see External power supply [} 57]).
See Connecting one or more readers [} 55] and Connecting one or more
SmartOutput modules [} 63] on wiring.

Machines can pose significant hazards:
– Cuts
– Burns
– Electric shocks
– Laser radiation
– Crushing
For safety reasons, only qualified people should therefore be allowed to
operate hazardous machines. Unauthorised persons must not be able to
put hazardous machines into operation.
An option to switch off the machine without authorised identification media
further increases operational safety.
Risk of injury due to incorrect programming
The SREL3 ADV system is not suitable as a sole disconnecting device. A
contactor activated via the controller must never be the only means to
switch off a machine.
1. Use the SREL3 ADV system as an additional disconnecting device only,
not as the sole one.
2. Use the actuated contactor in a series circuit with the machine's
emergency stop switch only.
