The OPTEX OVS-02GT sensor is the perfect sensing solution for automatic gates and barriers as it is easy to install above-ground on a wall, pole, or barrier housing, replacing the ground loop and functioning as a ‘Virtual Loop’. Our tech team take us through the seamless installation process.
The OPTEX OVS-02GT series is the perfect sensing solution for automatic gates and barriers as it is easy to install above-ground on a wall, pole, or barrier housing, replacing the ground loop and functioning as a ‘Virtual Loop’. This makes it suitable for almost any application, especially in challenging environments presented by the type of road surface or restrictions due to legislation. The sensor can be used for traffic management, vehicle protection, and security purposes.
Step 1: Mounting the unit
First step is to set the sensor to the correct mounting height of 500mm (20inch) from the ground, the sensor can be mounted on a wall or barrier. [should we include where it can be mounted – walls? Barriers?] In the quick reference guide supplied there is a mounting template, simply cut this out and attach to where the sensor will be mounted. Drill the holes for mounting and cabling.
The next step is to disassemble the sensor. There are two screws to do this, one at the top and one at the bottom. Once you have removed the sensor from the housing you need to prepare the housing for mounting. There are four rubber seals for cabling, select which one is required to run your cable and snip the rubber seal. Route the cable from the mounting surface through the sensor housing. The housing is now ready for mounting.
You can now prepare the wiring of the sensor. First open the rubber cap from the sensor unit. Connect the power and output cables to the terminal block. Ensure the power supply voltage is between 12 and 24V AC/DC. Feed the cable through the roof of the rubber cap and close. Fit the sensor into the housing and slide down to click into place.
With the sensor now in place, you can set the angle to its correct position by simply turning it to the required position. Once this is finalised you can put the bottom and top covers back on.
Step 2: Configuring the App
To indicate that the sensor is receiving power, the LED on the front of the sensor will light up blue. Open up the OPTEX Virtual Loop app, available in Apple Store and Google Play. The app will scan for the device, select the device which will in-turn connect to the app and the LED will blink blue. You will now be asked to set a password for the device. Once the password has been set, you will need to add the site information and then the application parameters.
The LED will now flash blue and green whilst the calibration is in progress. Do not enter the detection area while this is taken place. Once complete the LED will blink green.
The sensor is now ready to be checked. In standby mode the LED will blink green and when there is a detection it will blink red.
First turn on the area check mode.
Test the detection area with human traffic. The app will show detection. By doing the human walk test the sensor learns human data. This is how the human cancellation setting works.
Now turn off the area check mode and perform the area check with a vehicle.
Test the detection for the vehicle at short, mid and long range to make sure detection is set correctly. Check human traffic again, this time the LED should blink green to show that there is no human traffic detection. You can now logout of the app and set of the OVS-02GT is complete.
