x,y is the time in minutes and seconds after which the detector will
return to the ‘in-active’ state even though the vehicle may still be
present. (x – time in minutes, 0 to 255; y – time in seconds, 0 to 59).
Default is x= 5, y = 0. i.e. 5 minutes recovery time.
N.B. Applicable to SCOOT and Stop Line Detectors only.
