SICK nanoScan3 I/O

RSSI Received Signal Strength Indicator (RSSI): Indicator of the strength
of t
he received signal. A higher value corresponds to a better
reception. There is no universal relationship between a physical
quantity and a specified RSSI.
Safety output A safety output provides safety-related information.
S
afety 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 required for the mirror of a safety
la
ser scanner to complete one rotation.
SIL Safety integrity level
SILCL SIL claim limit (IEC 62061)
Static control input A static control input is a dual-channel control input, which evalu‐
a
tes the status of every channel as the value 0 or 1. The signal
states of one or more static control inputs give a unique signal pat‐
tern. This signal pattern activates a monitoring case.
Test rod The test rod is an opaque, cylinder-shaped object used to check
the 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 I/O Universal I/O can be configured as universal input or as universal
out
put.
Universal input Depending on the device, a universal input can be used for reset‐
ting, external device monitoring (EDM), standby, or restarting the
protective device, for example. If standby is activated by a univer‐
sal input, the standby must not be used for safety applications.
Certain universal inputs can also be used in pairs as a static con‐
trol input.
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.
Simple switching functions can be triggered with the warning field,
e.g. a warning light or an acoustic signal can be triggered if a per‐
son approaches, even before the person enters the protective
field.
The warning field must not be used for safety applications.
