Technicial specifications

PRODUCT FEATURES

1) Reset Switch:The reset switch enables the detector to be manually reset during registering and testing

and it is a process of system recovery

2) Selectable Pulse Time:This feature sets the length of time that the pulse relay will be lasting for 1S or 0.5

Seconds

3) Pulse Relay Selection:The Pulse Relay may be configured to activate on detection of a vehicle or when

the vehicle leaves the loop

4) Sensitivity Reinforcement:This feature sets the un-detecting level to a maximum sensitivity to prevent

failing to detect vehicles as big trucks

5) Switch Sensibility Adjustable:4 sensitivity setting are available on the switches to change sensitivity

6) Switch Frequency Adjustable:4 frequency settings are available to prevent signal interference with

neighboring loops

7) Filtering Option:This option is used to provide a delay between detection of the vehicle and switching

of the output relay. This relay is normally used to prevent false detection of small or fast moving objects

8) Permanent Presence Option:This feature ensures the detection of the vehicle will be maintained when

the vehicle stays within the loop area for extended periods

Use and operational
On power the vehicle loop will automatic correction. It will last 1 second, when correction,
on screen 2 LED shows Do not leaving car on the loop when it correction .If successful ,the
screen “check” LED turn off., The screen “check” LED turn on and the relay will action When
car through. If fail check loop, the LED blinking at 1Hz.

Frequency adjust

To avoid Crosstalk, please to select different frequencies and screened cables. There are 4 opt
frequency .The can be altered by means of DIP1, DIP2Switch.

Sensitivity adjust
The sensitivity can be adjusted on the front of the housing by means of a DIP3,DIP4,DIP5
sliding switch. Specific set the table below. In trial runs, first sensitivity in the lower stalls, After
the actual if test vehicle detection no response should be increased sensitivity to stall, so
repeated several times until the detector stability for normal work.

Filter option
When the environment is larger electromagnetic disturbance, resulting in frequent detector
misoperation, turn the DIP6 switch on to increasing the filter coefficient, filtering disturbance.
Please note that when the environment normal turn DIP6 on position. The may reduce detector
sensitivity detection or increase the delay time.
Note: If the loop parameters lay unreasonable it may also lead to frequent detector
misoperation. These loop parameters should be amended or re-buried loop.

Function output relay
* Pin5, pin 6, pin10: relay pulse output .It can be altered by means of DIP7-Switch
ON when car entry loop, the pin5, pin6 close conduction after 500ms switch-off.
OFF when car away loop, the pin5, pin6 close conduction after 500ms switch-off.
* pin3, pin4, pin11: relay existence output. When the loop is occupied by the car or metal, the
Pin3, pin 4 close conduction until the car away loop. The duration decided by DIP8

Duration output time setting
The duration output time setting can be programmed by means of DIP8-Switch.
ON unlimited duration output (when car passing by loops, Duration output last all long
OFF limited duration output time:10 seconds (when overtime10seconds the car pass by
loops, vehicle will New Calibration/Reset .

Reset
When power on detector, or pressing the reset panel buttons, or in limited duration mode over
time there will detector reset operation. After reset, the detector will be initialized for a car-free
state.
