GATE SETTINGS: OBSTACLE DETECTION
Setting the Obstacle Detection
Parameter P�480 must be set to 5. Detection of motor torque change.
Smaller values mean obstacle is detected earlier.
Larger values mean obstacle is detected later.
P�171 =
100% (OPEN – Deceleration)
P�172 = 100% (OPEN – Acceleration)
P�173 = 100% (OPEN – Travel)
P�176 =
100% (CLOSE – Deceleration)
P�177 = 100% (CLOSE – Acceleration)
P�178 = 100% (CLOSE – Travel)
P�179 = 30% (Additional Factor Added into P.171-173 & 176-178)
Gate Settings: Obstacle Detection
Setting the Reduced Speed Sensor/Torque Change Sensor
The SpeedGate Inherent Entrapment Sensor (IES) will consist of a Reduced Speed Sensor/Torque Change
Sensor, the absolute encoder located under the brake disconnect switch in each column. The IES senses
the position of the gate for gate operation and reduced speed sensing when the gate has come into contact
with an obstruction. Additionally, the IES monitors torque via acceleration and deceleration.
The force exerted by the gate leaf must be adjusted so that under normal operating conditions, the
controller will sense when the gate has come into contact with an obstruction and will reverse to the cycle
starting position. The gate will wait at this position for a renewed command.
Setting the Obstacle Detection
It is the installer’s responsibility to set obstacle detection on-site. Only adjust the parameters listed below.
Refer to “Installation and Commissioning Checklist: Setting Gate Limits” on page 10 for a description of
how to use the Operator and setting/changing parameters.
The reduced speed sensor/torque change sensor has a number of parameters than can be adjusted to
fine tune the gate for its final installation location. Environmental factors, such as wind load and snow can
determine how the obstruction detection functions, as well as the height and width of the gate.
Sensitivity must be properly
tested after installation
in order to comply with
UL325 requirements.
