The inductance of a ground loop can be effected by a bad circuit board, improper wire size and distance of loop from loop detector, among other things. These malfunctions can cause your commercial entry gate to open or close too quickly or even open and close repeatedly, without warning. To ensure that your ground loop functions properly, be sure to carefully choose the correct loop selection when installing your entry gate. If you are experiencing any of above issues or are looking to install a new commercial entry gate opener, please seek professional assistance as these malfunctions can be dangerous and even life threatening. Please do not attempt to repair or install the entry gate alone, as this may cause bodily harm.
