Barco SP2K-C - Partial Restriction Zone Screen Side

145R5914712 /00 SP2K-C
B.4 Partial Restriction Zone screen side
Situation
This situation can occur if the inclination of the floor is smaller than that of the light beam. The Height (H)
between the floor and the light beam is smaller than the minimum Separation Height (SH) at the screen side of
the Hazard Distance range. This part must be fenced off as a Restriction Zone (RZ). The Restriction Zone
starts at the intersection point (white arrow) where the Height (H) equals the minimum Separation Height (SH).
The Restriction Zone ends at the end of the HD range. The Restriction Zone must be extended laterally by the
minimum Separation Width (SW). The red hatched area in the following illustration indicates the partial
Restriction Zone (RZ) towards the screen.
