Description
Diablo FA-T80 CoBRA sensor
Description and Functions
This is a Light Ranging Application device using sonar like techniques. It consists of a high power emitter and detector. Laser infrared is a stimulated coherent light in a narrow beam. Short high power pulses gives the device it’s exceptional range.
The output relay switches when the target detected is less than the threshold distance. The device threshold distance is set by learning, up to a maximum 8m. The fail secure output can be set N/O or N/C. The Green LED is power. The yellow LED is detect. Applications should be restricted to vehicle detection, or supplementary safety on shorter ranges.
Applications
Applications are for the detection of foreign objects in a known and controlled free space, like a driveway. In automation terms, applications are either to initiate or prevent a movement; activation or
safety. There are also security applications for intruder detection which are for alarm notification only
Position and limitations
The device should be mounted for a horizontal beam. CoherentInfrared beams work on objects with reflectivity of 10% to 90%. Pure black objects (<10%) absorb light more. Highly polished surfaces (>90%) reflect more.
Vertical or diagonal beams need to avoid the possibility of targeting (reflective) water puddles. The device is rainproof for horizontal mounting so consider additional sealing or a rainhood cover may be needed.
The lens needs to be kept clean. Heavy rain and fog may impair detection on longer range applications. Keep detection for pre-vention of movement (safety) applications to within 4m range.
Activation applications
Post mounted beams across a drive will respond to any object. Adjust the height and angle to be more selective to a vehicle as opposed to a child. The range can then be adjusted to fall short of pedestrian areas.
A driveway alarm has device directed along the drive, warning of cars or people entering. Set the threshold to end at the perimeter.
Barrier application
The device can be fixed to the barrier arm, or to the barrier cabinet. It is ideal for arms up to 4m without a tip support. Cabinet mounting is safer but only applies to the height the device is set at.
Fixed to an arm replaces a safety edge, but consider the response time of 100ms and adjust the angle to allow for distance covered in 100ms
On the gate application
Devices can be fixed to the back of a gate to watch for obstacles in the path of the gate while opening. Note the first gate to open (right) can be set to over-reach the length of the gate by a foot. The second leaf needs to be set at the same length as the gate leaf, or it will see the first leaf begin to open.
Fixed device application
Fixed devices are used to protect crush zones behind a gate (left leaf). They also protect against entrapment. The contact is set to N/C and the function to pause the gate during opening. As a safety device we recommend thresholds up to 4m because of over sensitivity in bad weather.
