Inverted Display
For applications that require the emitter and receiver to be
inverted (with the status indicator ends at the “top”), the
7-segment displays on EZ-SCREEN emitters and receivers
can be inverted for easy reading. Press the Invert Display push
button, located next to the DIP switches, under the access cover
(Figure 4-6). A single momentary push is required; if pressed too
long (longer than 1/2 second), the display will not invert.
A spare access cover with inverted label and an inverted label
for the display are provided in the hardware packets for each
emitter and receiver (or see Section 2.5 Replacement Parts).
Remove the standard access cover by removing the screw-on
security plate and gently pulling the cover out. Place the inverted
label over the existing label on the display (adjacent to the DIP
switches) and snap the inverted-label access cover into place;
replace screw-on security plate if desired.
