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.
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.
! Cable use in Class 2 circuit to an external device shall be type CL2, CL2P, CL2R, CL2X or
other cable with equivalent or better electrical, mechanical, and fl ammability ratings.
Check for proper operation:
•
When a connected device
is triggered, the “UL” LED
will illuminate to indicate an
input. The “Stop” LED will also
illuminate if there is more than
one Monitored device connected.
•
It is important to note that if
more than one Monitored device
is connected to this terminal, the
“UL” LED will be illuminated. This
alone is inconsequential.
•
The “Stop” LED will flash if there
is a failure with at least one
Monitored entrapment sensor
and the gate operator will be
rendered inoperable.
