Example 2: SMD machine protection
The access to a dangerous area must be enabled in order to carry-out maintenance procedures. The
access must be allowed by stopping only the specific area by opening the doors and not the entire
machine.
Fig. 4 Doors control by means of safety photocelss
Solution:
SG-BWS-T4 is able to detect the door opening by using one or more photocells by
intersecting the interrupted beams, guaranteeing the safety condition.
Advantages:
all the safety interlocks can be replaced on each door thanks to the use of photocells
and so reducing the plant cost as well as increasing flexibility.
