Main Features:
1) Reset Switch : The reset switch enables the detector to be
manually reset during commissioning and testing . This results in
the detector re-tuning the sensing loop and becoming ready for
vehicle detection ;
2) Selectable Pulse Time : This feature sets the length of time
that the pulse relay will be energized for 1 Second or 0.5 Seconds
;
3) Pulse Relay Selection : The Pulse Relay may be configured to
energize on detection of a vehicle or when the vehicle leaves the
loop ;
4) Sensitivity Boost : This feature sets the undetect level to
maximum sensitivity and is used to prevent loss of detection of
high-bed vehicles ;
5) Switch Selectable Sensibility : 4 sensitivity setting are
available on the switches to allow flexibility in configuration ;
6) Switch Selectable Frequency : 4 frequency settings are available
to prevent cross-talk between adjacent loops ;
7) Filter Option : This option is used to provide a delay between
detection of the vehicle and switchiing 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 ensure detection of the
vehicle will be maintained when the vehicle is parked over the loop
for extended periods .

Wiring diagram
Operation and Indication
While the detector is tuning, the green Channel LED and red Power LED will be turn on. It remain about 2 seconds, then the green LED turn off. If a loop fault exists the Channel LED will come on and flash indicating a fault. If the fault is self-healing the detector will continue to operate.The green channel LED will also glow whenever a vehicle is detected passing over the inductive loop. The red Power LED at the top of the unit will remain on to indicate that the unit is powered.
Frequency To eliminate interference of two neighbouring wire loops or loop detectors, the frequency can be altered.
Sensitivity The sensitivity of the detector allows the detector to be selective as to the change of inductance necessary to produce an output. There are four sensitivity selections and are set as follows by DIP3 and DIP4 Switch.
Automatic Sensitivity Boost
Automatic sensitivity boost is selected by DIP5 switch on the front of the enclosure and is set as follows: OFF - Disabled, ON – Enabled. Automatic sensitivity boost causes the sensitivity to be boosted to a maximum on detection on the vehicle, and maintained at this level during the presence of the vehicle over the loop. When the vehicle departs the loop and detection is lost the sensitivity reverts to the pre-selected level.
