ACCESSORY CONNECTIONS
!
TECHNICAL TIP:
For more information regarding accessory connections to the control board
and individual input terminal functions, refer to “Appendix (A)” pages 42-43.
Re-Open
(Monitored Input Terminal)
The “Re-Open” input terminal
protects
against entrapment in the closing
direction ONLY. Input will reverse the
gate all the way to the Open Limit
when
a connected device it triggered. see pages
10-11.
UL
(Monitored Input Terminal)
The “UL” input terminal
protects against
entrapment in both the opening and
closing directions. Input will reverse
the gate momentarily in the opposite
direction it was traveling
when a
connected device it triggered. see pages
10-11.
Check for proper operation:
When a connected device is triggered, the “Re-
Open” LED will illuminate and, if more than one
Monitored device connected, the “Stop” LED will
flash rapidly to indicate an input.
!
If more than one Monitored device is
connected to this terminal, the “Re-Open” LED
will be illuminated. This alone is inconsequential.

NOTE:
The “Stop” LED
will be flashing if there
is a failure with at
least one monitored
entrapment sensor and
the gate operator will
be rendered inoperable.
