Intended use
WARNING
Caution - Risk of injury!
TwinSAFE components may only be used for the purposes described below!
The TwinSAFE EtherCAT Box expands the application range of the Beckhoff system with functions that
enable it to be used for machine safety applications. The TwinSAFE Boxes are designed for machine safety
functions and directly associated industrial automation tasks. They are therefore only approved for
applications with a defined fail-safe state. This safe state is the wattless state. Fail-safety according to the
relevant standards is required.
The TwinSAFE EtherCAT Box allows the connection of:
24 V
DC
sensors such as
• emergency stop push buttons, rope pull switches, position switches, two-hand switches, safety mats,
light curtains, light barriers, laser scanners etc.
• Safe sensors, which use a 24V
DC
supply and send safe OSSD signals.
WARNING
The fail-safe principle!
The basic rule for a safety system such as TwinSAFE is that failure of a part, a system component or the
overall system must never lead to a dangerous condition. The safe state is always the switched off and wat-
tless state.
WARNING
Power supply from SELV/PELV power supply unit!
The TwinSAFE components must be supplied with 24 V
DC
by an SELV/PELV power supply unit with an out-
put voltage limit U
max
of 36 V
DC
. Failure to observe this can result in a loss of safety.
WARNING
System limits
The TÜV SÜD certificate applies to this TwinSAFE component, the function blocks available in it, the docu-
mentation and the engineering tool.
TwinCAT 3.1
and the
TwinSAFE Loader
are permitted as engineering
tools. Any deviations from these procedures or tools, particularly externally generated xml files for Twin-
SAFE import or externally generated automatic project creation procedures, are not covered by the certifi-
cate.
WARNING
Commissioning test
Before the EP1918-0002 can be used for the safety task, the user must carry out a commissioning test so
that sensor and actuator wiring faults can be ruled out.
CAUTION
Follow the machinery directive!
The TwinSAFE components may only be used in machines as defined in the machinery directive.
CAUTION
Ensure traceability!
The buyer has to ensure the traceability of the device via the serial number.
