Delay DIP Switches
Delay is the time added after a vehicle arrives in the detection area but before the output is activated. During the
delay interval the output relay will remain de-activated, requiring that the vehicle stay in the detection area for
the full delay time before activating the output. This is useful at sites where right turns on red are allowed. This
allows a vehicle to arrive at a red signal, come to a full stop, and proceed to make a right turn without the detector
ever activating and placing a call into a phase. This interval is indicated by the red Detect LED blinking slowly at
200 milliseconds on followed by 200 milliseconds off repeatedly until the interval is complete. Delay time can be
set from 1 second to 63 seconds in 1 second increments. The following table shows the switch settings for the
various possible time values.

Extension DIP Switches
Extension is the time added after a vehicle leaves the detection area. During this interval, the output will remain
activated. If another vehicle arrives during this extension interval, the remainder of the extension time is canceled
and the detector returns to the normal presence state. This interval is indicated by the red Detect LED blinking
fast at 50 milliseconds on followed by 50 milliseconds off repeatedly until the interval is complete. Extension time
can be set from 0.25 seconds to 15.75 seconds in 0.25 second increments. The following table shows the switch
settings for the various possible time values.
