9.3.3 Daily functional checks of the protective device
The effectiveness of the protective device must be checked daily or prior to the start of
work by a specialist or by authorised personnel, using the correct test rod.
WARNING
Do not operate the machine if the green or yellow LED is lit during the test!
If the green or yellow LED lights up during the test even for a short period, work must stop
at the machine. In this case the mounting and the configuration of the multiple light beam
safety device must be checked by qualified safety personnel (see chapter 7 and chap-
ter 10).
Testing the light path between sender and receiver
 Prior to covering each light beam with a test rod, check whether …
– the green LED lights up on the M4000 with de-activated internal restart interlock.
– the yellow LED lights up on the M4000 with activated internal restart interlock
(“Reset required”).
If this is not the case, ensure that this condition is reached. The test is otherwise
meaningless.
Only M4000 Advanced:
 Completely cover each light beam with a test rod that is not transparent to light (at
least 30 mm diameter) at the following positions:
– immediately in front of the sender
– in the middle between sender and receiver (or between the deflector mirrors)
– immediately in front of the receiver
– when using deflector mirrors: immediately before and after the deflector
Only M4000 Advanced A/P:
 Completely cover each light beam with a test rod that is not transparent to light (at
least 30 mm diameter). Hold the test rod in the following positions with your arm out-
stretched:
– immediately in front of the M4000 Advanced A/P
– in the middle between M4000 Advanced A/P and M4000 Passive or another mirror
deflection (e.g. deflector mirror PSK45)
– immediately in front of the M4000 Passive or another mirror deflection (e.g. deflector
mirror PSK45)
– when using deflector mirrors between M4000 Advanced A/P and M4000 Passive:
immediately before and after the deflector
