Single Channel Vehicle Access Barrier Sensor Inductive Vehicle Loop Detector

Single Channel Vehicle Access Barrier Sensor Inductive Vehicle Loop Detector

Description

Model No.: EF-PD132

This loop detector used for wherever vehicles have to be detected, Monitoring and safe-guarding access ways or for counting vehicles. Output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems or activating card dispensers in parking lots. Uses advanced microprocessor technology and can work in diverse environments. Has two way output relays: one is unlimited output when loop is permanently covered and while the other is multiple mode that can be set by users.

Functions & 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 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 Reinforcement:

This feature sets the undetecting 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.

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 neighboring 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.
