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.

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

Factory Settings:

Sensitivity Boost – automatic during detect except in the

highest sensitivity setting (9).

·          Set to HI frequency

·          Set to Medium sensitivity (5)

Factory Options:

·          Extend/Delay in the OFF position

      Presence lengths of 15, 30, 60 minutes or permanent.

·          Presence time set to 1 hour

      Pulse lengths of 250mS, 500mS, 1, 2 or 4 seconds.

·          Pulse length set to 250msec

      Extend times of 0, 2, 5 or 10 seconds.

·          Relay 1 = fail-safe

      Delay times of 0, 1, 2 or 4 seconds.

·          Relay 2 = fail-secure

      Relay 1 fail-safe or fail-secure.

      Relay 2 fail-safe or fail-secure.
