Rear Panel DIP Switch Selections
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).
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.
- 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.
