A
ctive opto-electronic protective device responsive to diffuse reflection (e.g. S300, see
also IEC 61496<3)
The monitoring cases are switched using the control inputs. The S300 Advanced has one
static, the S300 Professional and the S300 Expert have two static or dynamic control
inputs (for incremental encoders) as well as an optional static control input.
Enhanced function interface = safe SICK device communication
A device that electronically monitors the relay or contactor operated by the protective
device prior to each new start.
Protective fields and warning fields form the so-called field set.
Two safety laser scanners in an EFI system. The control signals for monitoring case
switching are applied to the inputs on the host. The guest is connected to the host via EFI
and receives from the host the input information for local monitoring case switching.
A component that produces electrical pulses in proportion to a movement. For these
pulses, various physical parameters can be derived, e.g. velocity, direction of travel, etc.
A field set is allocated to a monitoring case. Monitoring case switching is performed using
the control inputs. In this way the S300 can be adapted to the operating mode of the
machine or system that it monitors.
Plastic part with window for light output. The optics cover is available as a spare part.
Output signal switching device = The OSSD output is the switching output on the S300.
This is a semiconductor output and is periodically tested for correct function. The S300
has two OSSD outputs that operate in parallel; for safety reasons these must be evaluated
using two channels.
The protective field secures the hazardous area on a machine or vehicle. As soon as the
safety laser scanner detects an object in the protective field, it switches the OSSDs to the
OFF state and thus initiates the shutdown of the machine or stop of the vehicle.
Reflection of luminance. A measure of the remission is the level of remission defined as
the ratio of the luminance reflected from a surface in the measuring direction and the
luminance of a completely matt white surface (white standard).
The minimum size of an object that is acquired by the protective device and is guaranteed
by the manufacturer.
The restart interlock is a protective device. In certain situations it prevents the machine
from automatically restarting. This applies, e.g., after the scanner function has triggered
during a dangerous machine state, after a change to the operating mode or the method of
activation of the machine, or after the change to the start control device on the machine.
If the internal error detection detects an error that prevents the correct operation of the
safety component, the SICK safety component adopts a defined, safe state. The safety
component remains in this state until the error or the cause of the error has been rectified.
Error cases in which the safety component adopts a safe state include:
• safety-related internal errors,
• invalid input signal conditions,
• supply voltage loss,
• loss of the assured detection capability.
Contains the configuration memory and all electrical connections. In this way the S300 can be
easily replaced. After re-commissioning the configuration is read from the system plug; the
S300 is then, normally, ready for use.
