Rear Panel DIP Switch selections
Relay 1
Extend – switch 1 is for extending the detector output after
the vehicle has left the loop. Switch 1 in the OFF position
provides no extension. Switch 1 in the ON position provides
a 5 second extension once the vehicle leaves the loop. This
extension applies to relay 1 only.
Delay – switch 2 is for providing a 2 second delay, detector
will ignore the vehicle until the vehicle has been present over
the loop for 2 seconds. Switch 2 in the OFF position
provides no delay. Switch 2 in the ON position provides for
the 2-second delay. This delay applies to relay 1 only.
Presence Time – switch 3 provides for either a 1 hour
presence or permanent presence. Switch 3 in the OFF
position provides for 1 hour of presence. Switch 3 in the ON
position provides for permanent presence. The above
presence settings apply to relay 1 only. (Other options are
available).
Relay 2
Pulse Length – switch 4 provides for either a 250mS pulse
length or a 500mS pulse length. Switch 4 in the OFF position
provides a 250mS (standard) pulse length.
Switch 4 in the ON position provides a 500mS pulse length.
Operating Mode – switch 5 and switch 6 determine the
operating mode for Relay 2. The four modes are as follows:
Switch 5 and switch 6 OFF provides pulse-on-entry.
Switch 5 ON & switch 6 OFF provides pulse-on-leaving.
Switch 5 OFF & switch 6 ON provides for presence.
Switch 5 and switch 6 ON provides a fault output.
Front Panel Selections
Sensitivity – controlled by front panel rotary switch.
•
0 = Low sensitivity
•
9 = High sensitivity
Medium sensitivity is used for most applications; this is a
setting of 4 or 5. Always use the lowest sensitivity setting
that detects the desired vehicles.
Frequency – four separate settings controlled by front panel
DIP switches.
•
2+1 = High
•
2+0 = Medium High
•
1+0 = Medium Low
•
0+0 = Low
Reset – front panel reset performs a hard reset of the
detector.
