SICK TiM361S

7 Error behavior
7.1 General
A non-hazardous failure of the device occurs:
•
When the device switches to defined status 2 and/or 3 without request of the
safety function.
•
When the device switches to defined status 2 and/or 3 in the event of a detected
internal error.
A hazardous undetected failure occurs:
•
When the device fails to switch to defined status 1, defined status 2 and/or
defined status 3 upon request of the safety function.
7.2
Detected errors
The device detects some internal errors merely to improve its availability and support
troubleshooting in the event of an error.
The device has a diagnostic coverage (DC) of zero in accordance with
EN ISO 13849-1:2015 PL b. The internal errors detected by the sensor cannot be
used to increase the DCs within the meaning of this standard!
7.3 Undetected errors and faults
The device will not detect the following errors and faults, among others:
•
Digital inputs: short to ground, wire break, short-circuit, cross-circuit to the digital
inputs for field set selection (IN1, IN2, IN3, IN4), making it possible to select an
incorrect field set.
•
Digital outputs: short to ground, wire break, short-circuit, cross-circuit to the digital
outputs for object detection (OUT1, OUT2, OUT3) and Device Ready (OUT4), with
the effect that the defined statuses can no longer be detected by the downstream
controller. This also applies in the case of incorrect wiring of the connection pins.
•
Status indicators: Failure of the status indicators for field set status, with the
result that the object detection is not correctly displayed optically on the device.
•
Contamination: Contamination of the optics and/or the front screen, causing
impairment, reduction or complete loss of detection capability, and the device no
longer being able to perform the safety function.
•
Ambient light: Malfunctions due to faults of other scanners and light sources
within the level of the scan field, causing impairment, reduction or complete loss
of detection capability, and the device no longer being able to perform its function.
•
Incorrect measurements: Measurement of objects with edges and/or corners
and/or which are moving too quickly (determined by the measurement procedure)
can result in incorrect distance values, causing impairment, reduction or complete
loss of detection capability, and the device no longer being able to perform the
safety function.
•
Blind zone: Objects, especially covering objects, located within the blind zone
extending f 0.05m from the measurement origin of the device, causing impair‐
ment, reduction or complete loss of detection capability, and the device no longer
being able to perform the safety function.
WARNING
Risk of ineffectiveness of the protective device!
Undetected errors and faults can cause impairment, reduction or complete loss of
detection capability, such that the device is no longer able to perform the safety
function.
