Enabling Floating Blanking (Receiver Switch 4)
See Setting a Floating Blanking Window, page 3-7 for a discussion of floating blanking and
instructions for setting a floating blanking window. Table 2-10 shows the selector switch
settings for floating blanking.
Enabling Programmable Fixed Blanking (Receiver Switch 5)
See Programming a Fixed Blanking Window, page 3-4 for a discussion of programmable
fixed blanking and instructions for programming a fixed blanking window. Table 2-11 shows
the selector switch settings for enabling programmable fixed blanking.
Setting Scanning Range (Receiver Switch 6)
Scanning range is the maximum distance between heads at which the LEDs in the transmitter
can be read by the phototransistors in the receiver. Switch 6 allows you to select one of two
scanning ranges for your Shadow 8 heads. The long range option, which is the default setting,
is 65 ft. (20 m) minimum. The short range option is 26 ft. (8 m) minimum. Selecting the short
range setting can help to prevent cross-talk when there are many light curtains operating in a
small space. Table 2-12 shows the selector switch settings for scanning range. Only switch
SWB 6 needs to be set; switch SWA 6 is not used.
Enabling Machine Test Signal (MTS) (Transmitter Switch 2)
Machine Test Signal (MTS) is not a supported Shadow 8 feature. Leave Transmitter switch 2
in its default OFF position. Do not enable MTS by moving switch 2 to ON.
