SICK scanGrid2 I/O User Manual

Response time The protective device’s response time is the maximum time
be
tween the occurrence of the event leading to the sensor’s
response and supply of the switch-off signal to the protective
device’s interface (for example OFF state of the OSSD pair).
Restart interlock The restart interlock prevents the machine from automatically
s
tarting up, for example after a protective device has responded
while the machine is operating or after changing the machine’s
operating mode.
The restart interlock can be implemented in the protective device
or in the safety controller.
A command to reset the protective device must be given, for
example using a reset pushbutton, before the machine can be
restarted.
Safety function Function of a machine whose failure can result in an immediate
incr
ease of the risk(s). (ISO 12100)
Safety output A safety output provides safety-related information.
Safety outputs are OSSDs, for example, or safety-related informa‐
tion on a safety-related network.
Scan cycle time The scan cycle time is the time the sensor needs for a complete
sc
an of its detection area.
Example: Time required by the mirror of a safety laser scanner for
one rotation.
SIL Safety integrity level
SILCL SIL claim limit (IEC 62061)
Test rod The test rod is an opaque, cylinder-shaped object used to check
t
he detection capability of the active opto-electronic protective
device. The diameter of the test rod is the same as the resolution
of the active opto-electronic protective device.
Universal output A universal output outputs a signal depending on its configuration,
e.g. if the reset pushbutton needs to be pushed or if the optical
cover is contaminated. A universal output must not be used for
safety functions.
Warning field The warning field monitors larger areas than the protective field.
S
imple switching functions can be triggered with the warning field,
e.g. a warning light or an acoustic signal can be triggered if a
person approaches, even before the person enters the protective
field.
The warning field must not be used for safety applications.
