15 Regular checkout and test
NB! Make sure that following checkout and test routines are carried out on a regular basis. Failure to test
properly could result in serious injury to personnel. All tests must be performed by qualified personnel. A
copy of the checkout results should be kept with the machine records.
How often the checks above must be done depends on the environment and the individual conditions
where the barrier is installed.
All relevant local and national rules must be adhered to when estimating the required frequency of checks.
In case there is any doubt, a local or national safety organisation should be consulted.
Repeat Tests 1 and 2 on a daily basis. Repeat Tests 1 to 6 at least every six months. Failure to test properly
could result in serious injury to personnel.
1. Guide the test object through the entire protective f i eld approximately in the middle of, and 1 m from the
front of transmitter / receiver with the appropriate size of the tool, thin side for the 14 mm resolution and
the thicker side for 30 mm resolution.
Check this in:
Manual reset;
Automatic reset;
2. Activate the TEST/RESET (>2.5 s). Check that the safety outputs of the Focus II system become volta-
ge free. The red LED (4) is lit and the machinery is stopped.
3. Check that the mounting distance of the Focus II system is equal to or greater than the minimum safe
distance from the danger point. See 3.3 and 3.4 for further information.
4. Make sure that all access to the danger point not protected by the Focus II system is guarded by other
means, such as gates, fencing or other approved methods. Verify that all additional guarding devices
are installed and operating properly.
5. Make sure the operator is not able to stand between the Focus II system detection zone and the ha-
zards in the machine. Verify that the light curtain can only be reset from a position outside and where
the hazardous machine area can be viewed.
6. Inspect the electrical connections between the guarded machine's control system and the Focus II
system. Verify that they are not damaged and properly connected to the machine so that a stop signal
from the Focus II system results in an immediate halt of the machine's cycle.
