Check for proper operation:
• When a connected device
is triggered, the "UL" LED
will illuminate to indicate an

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.
