EdGE, REVERSING EDGE
This alarm indicates that the reversing edge connec-
tion (input 17) is missing. The Digital Gateway moni-
tors the connection every time the door is fully open.
If the connection is missing for two seconds or more,
the door will remain open, the display message
EdGE, and the RE input LED will blink. Reconnect the
input and reset the Digital Gateway. (See Figure 13.)
The message EdGE will be displayed, but will not
blink if the door came down on something activating
the reversing edge. The door will then reverse to the
open position. The display will show EdGE like Figure
13, but the LED will be off.
