1-12 Introduction
A detailed discussion of floating blanking and instructions for enabling a one-channel
blanking window are provided starting on page 3-7.
Programmable fixed blanking and floating blanking can be used at the same time (see
page 3-9).
The light curtain’s minimum object sensitivity (see page 1-7) increases when a light beam is
“blanked,” and the safety distance must be increased accordingly (see Calculating the Safety
Distance, page 2-2).
Other Shadow 8 Features and Options
Shadow 8 is designed for uncompromising safety and durability under real world conditions.
The light curtains have passed stringent environmental stress tests for shock, vibration,
impact, exposure to temperature extremes, dust, humidity, and electrical abnormalities.
Shadow 8 comes with two auxiliary outputs that mimic the safety outputs. See Wiring
Auxiliary Output(s), page 2-44 for more information.
Shadow 8 optic heads come with universal mounting brackets attached at both ends (see
Figure 1-1, page 1-3). Mounting brackets, which can be rotated ±8°, are used to properly
align the Shadow 8 heads during installation. An additional bracket can positioned at the light
curtain’s midpoint with a T-slot mount to improve stability, and two brackets with T-slot
mounts can be used instead of end brackets where mounting space is restricted. See Universal
Mounting Brackets, page 2-15.
Shadow 8 options that you can purchase from Wintriss include mirrors for two- and three-
sided guarding (see Figure 2-11 and Table 2-4, page 2-24) and stands for mounting optic
heads and mirrors (see Figure 2-4 and Table 2-1, page 2-17).
Shadow 8 Maintenance
Shadow 8 continues working silently with no adjustment and little maintenance required.
You should clean the lens window(s) periodically if the working environment is particularly
dusty, dirty, oily or smoky (see Checking and Cleaning Lens Windows, page 4-7). You should
also periodically verify proper alignment (see Aligning and Tightening Down Shadow 8
Heads, page 2-49 and Checking Alignment, page 4-7). If you are using the optional control,
you will need to replace the relay board if a safety relay fails (see Checking and Replacing
Control Relays in Optional Shadow 8 Control Box, page 4-9).
