EZ-SCREEN LP
Instruction Manual Cascadeable EZ-SCREEN
Example 1:
Machine Interface Cordset (L1): 4.6 m (15')
Sensor Interconnect Cordset (L2): 0.3 m (1')
Sensor Interconnect Cordset (L3): 15.2 m (50') or shorter
Sensor Interconnect Cordset (L4): 0.3 m (1')
7.5 Response Time for Cascaded Light Screens
Response time is an important factor in determining a light
screen’s separation (safety) distance. For cascaded (or “daisy-
chained”) EZ-SCREEN LP systems, that response time is
dependent on the number of light screens, the number of beams
in the light screens, and their positions in the cascade. It can be
calculated easily, in two ways:
• Individually for each light screen in the cascade (safety
(minimum) distance is calculated for each light screen in the
cascade), or
• Based on the worst-case time for the entire cascade (where
all light screens in the cascade have the same separation
distance).

Example 2:
Machine Interface Cordset (L1): 4.6 m (15')
Sensor Interconnect Cordset (L2): 0.9 m (3')
Sensor Interconnect Cordset (L3): 15.2 m (50') or shorter
Sensor Interconnect Cordset (L4): 0.9 m (3')
*Multiple DELP..-.. Cordsets may be required.
