Daily functional checks of the protective device
The effectiveness of the protective device must be checked daily by a specialist or by
authorised personnel, using the correct test rod.
Always test along the complete hazardous area to be protected, never solely at the
mounting position of the safety light curtain.
How to check the effectiveness and correct function of the safety light curtain:
Select the correct test rod depending on device resolution.
Do not operate the machine if during the test the green LED (OUT) is lit or the orange
LED (RES) flashes!
If
during the test
the green LED lights up — even for a short period — or the orange LED
flashes, work must stop at the machine. In this case the mounting and the configuration of
the safety light curtain must be checked by qualified safety personnel (see chapter 4).
Before
inserting the test rod, check that the green OUT LED is illuminated if the Reset
function is deactivated or that the orange RES LED is flashing if the Reset function is
activated (“Reset required”). If this is not the case, ensure that this condition is
reached. The test is otherwise meaningless.
Move the test rod slowly through the area to be protected, as shown under
Then, guide the test rod along the edges of the area to be protected as shown under
in Fig. 45. This procedure allows you to test if the presence detection/reaching behind
protection is functioning correctly (see 4.2 “Steps for mounting the device” on page 27).
During all thorough checks on the miniTwin2 only the OUT LED is allowed to illuminate red
and the orange RES LED must
never
flash.
