OPERATION

Power up

Upon power up the detector initializes by automatically tuning to the loop. The green LED indicates that the detector is 
powered and operational.

Frequency setting

The operating frequency of the loop is a function of the specific loop inductance and DIP switch settings 3-4. The 
primary purpose of the frequency setting is to allow the installer the ability to set different operating frequencies for multi-
loop installations, recommended to prevent crosstalk/interference from adjacent loops. After changing the frequency 
setting, press the Frequency Count switch to re-initialize the detector. To check the operating frequency of a loop refer 
to the Frequency Count section. To determine whether crosstalk between adjacent loops is occurring, refer to the   
Sensitivity Display section.

Sensitivity Display

The sensitivity display simplifies the installation process by displaying the sensitivity setting required to detect a vehicle 
on the loop. To use this feature, observe the display while a vehicle is moving into position on the loop, note the number 
displayed, then adjust the sensitivity setting (rotary switch) to the displayed position.
During normal operation, when a vehicle is not on the loop, the display is blank. The effects of crosstalk or other 
interference can be observed on the display when the loop is vacant. Interference or crosstalk will cause the display to 
indicate a level, typically 8 or 9. It may be necessary to observe the display for a minute or so to see this effect. Change 
the frequency setting to prevent crosstalk.

Sensitivity setting

The 10-position rotary switch allows for precise adjustment of detection level. The sensitivity level increases from 
position 0 thru 9 with position 0 being the lowest sensitivity. Typical applications require a setting of 3 or 4. The sensitivity 
display simplifies the installation process by displaying the sensitivity setting required to detect a vehicle on the loop.
To use this feature, observe the display while a vehicle is moving into position on the loop, note the number displayed, 
then adjust the sensitivity setting (rotary switch) to the displayed position.

Frequency Count / Reset

Press the Frequency Count switch and count the number of flashes on the red LED. Each flash represents 10kHz. To 
help to prevent crosstalk when multiple detectors are used for adjacent loops, perform a frequency count on each 
detector to confirm the operation frequencies are different. Following a frequency count cycle, the detector re-
initializes.

Automatic Sensitivity Boost 

The Automatic Sensitivity boost causes the sensitivity to increase following initial detection. This feature is useful to 
prevent dropout when detecting high-bed vehicles. The sensitivity returns to its normal setting after the vehicle exits the 
loop. Decimal point on the display indicates ASB on.

Output Relay

The pulse/presence switch allows the output relay to be configured for presence or one-second pulse on entry 
operation. When set to pulse operation, the display cycles through “P...U...L...S...E” repeatedly to indicate that the 
detector is set for pulse operation. When set to presence, the output relay remains activated while the vehicle is present 
on the loop.
