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. |
