Thorough check of the principal function of the protective device
SICK recommends the following procedure:
b
Watch the display and the status LEDs above the safety laser scanner’s display. If,
when the machine is switched on, at least one LED above the safety laser scan‐
ner’s display does not light up permanently, you must assume that there is a fault.
b
Test the function of the protective device by triggering the protective function once
and observing the safety output’s reaction using the reaction of the machine, for
example.
°
All applications: during the thorough check, observe whether the safety laser
scanner displays the interruption of the protective field using the LEDs
and/or the display.
°
Stationary application (hazardous area protection):
•
Interrupt the protective field using the supplied test object and observe
whether the machine stops.
°
Mobile application (mobile hazardous area protection):
•
Place the supplied test object in the path of the vehicle and observe
whether the vehicle stops.
OR
•
Activate a protective field, which is interrupted by at least one test object
and check the expected reaction (for example by an automatic thorough
check in the safety controller).
If the thorough check reveals a fault, the machine should be shut down immediately. In
this case, the mounting and electrical installation of the safety laser scanner must be
checked by appropriately qualified safety personnel.
Thorough check of the area to be protected
The area to be protected and the detection capability are checked during this thorough
check.
The thorough check covers the following points:
•
Changes in the detection capability (thorough check of all configured fields)
•
Modifications, tampering and damage to the protective device or the machine,
which lead to changes in the area to be protected or the position of the protective
field
SICK recommends the following procedure:
Hazardous area protection
b
Position the supplied test object at a number of points at the edges of the area to
be protected. The safety laser scanner must detect the test object at each position
and indicate the detection. How it is indicated depends on the configuration. The
number and position of sites where the thorough check is carried out must be cho‐
sen so that undetected access to the hazardous area is impossible.
b
If a number of protective fields are used (in different monitoring cases for exam‐
ple), check the edges of all protective fields.
Mobile hazardous area protection
b
Place the supplied test object in the path of the vehicle and check whether the
vehicle comes to a stop in time.
b
If a number of protective fields are used (in different monitoring cases for exam‐
ple), check whether the vehicle comes to a stop in time in all of the protective
fields.
