CONTROL BOARD SETUP
Obstruction Detection Sensor (ODS)
!
IMPORTANT: The appropriate “ODS” setting is dependant upon the gate installation and con-
struction. Set this feature accordingly. Additional Safety equipment should be used to reduce
possible risk of injury or vehicle damage.
“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 a Stop command
or the “Alarm Reset” switch has been
actuated. (refer to page 12)
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 “ODS” LED will indicate the following when it has been triggered.
Solid: Obstruction
Detected a sudden or abrupt increase in gate resistance.
Flashing: Overload.
Detected a more subtle, but sustained increase in gate resistance.
