■ Construction Sample of Interlock System
• For operating this product, construct the protective enclosure enclosing the range of the laser radiation for
protecting the exposure caused by the reflection of the laser radiation from the object being marked or the
surrounding objects, and also construct the interlock system at the same time. The following figure shows
the construction sample of the interlock system.
■ Operation at Interlock Input
As shown in the table below, this product outputs error state by canceling the interlock input and also stops the
