3.3 Mechanical Installation Considerations
Two factors have the greatest influence on the mechanical installation of the
EZ-SCREEN System:
• The required separation (safety) distance, and
• The presence of hard guarding.
3.3.1 Minimum Separation Distance (Ds)
Minimum Separation (Safety) Distance (Ds) is the minimum distance required
between the light grid and the closest reachable hazard point. Separation distance
is calculated so that the EZ-SCREEN Grid System will send a stop signal to the
machine when an object or a person is detected (by blocking a sensing beam),
allowing the machine to come to a stop by the time the person can reach any
machine hazard point.
After the Ds is determined, record the calculated distance in Section 6.4 (step
2) of this manual, and/or on the Daily Checkout Card.
