Obstruction Sensor (Primary Entrapment Protection)
! IMPORTANT:
The appropriate “ODS” setting is dependant upon the gate installation
and construction. Set this feature accordingly. Additional Safety equipment should
be used to reduce possible risk of injury or vehicle damage.
CONTROL BOARD SETUP
“ODS” Obstruction Detection Sensor
The Obstruction Sensor detects
obstructions in the path of the traveling
gate. The dial sets the amount of force
required to activate the operators inherent
obstruction detection.
Setting the dial to “0” will require the least
amount of force to activate;
Setting the dial to “100” will require the
maximum amount of force to activate.
UL325 standard requires an audio
alarm to go off after two consecutive
entrapment events sensed by the
Inherent Entrapment Protection of the
Gate Operator.
The audio alarm will sound for a period
of 5 minutes or until the “Stop” Button
or “Alarm Reset” Button is pressed. See
page 12 for more information.
When the Obstruction Sensor detects
an obstruction it will:
1. Stop the gate’s movement and reverse
it momentarily.
2. Bring the gate to a resting position.
3. Disable the Hold Open Timer feature
until the Gate Operator receives a new
command.
If second obstruction is detected before
the gate reaches either limit it will:
1. Stop the gate’s movement.
2. Disable the Gate Operator.
3. Sound the UL Alarm
4. A STOP command must be provided
to disable the alarm and continue
operation.
! TECHNICAL TIP:
The Status LED for the
“ODS” will indicate the following
when it has been triggered.
A. Solid: Obstruction.
Detected a sudden or abrupt increase
in gate resistance.
B. Flashing: Overload.
Detected a more subtle, but sustained
increase in gate resistance.
