Two Relay Garage Door Opener Inductive Loop Vehicle Detector CE Approval
The PD-232 is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied.

Loop connection wiring: | Maximum length 20 meters, twisted at least 20 times per meter |
Size of Housing: | 78x40x108 mm (L x W x H) |
Features :
Reset Switch. Pressing 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.
Switch selectable Sensitivity. The detect sensitivity is the minimum change in inductance
required to produce a
detect output. (%L/L). Eight sensitivity settings are available on
the switches to allow flexibility in configuration.
Sensitivity Boost. This feature sets the undetect level to maximum sensitivity and
is used to prevent loss of
detection of high-bed vehicles.
Filter Option. This option is used to provide a delay of 2 Seconds between
detection of the vehicle and switching
of the output relay. This delay is normally used to prevent false
detection of small or fast moving objects.
Extend Option. When switched on this feature extends the presence output relay
for 2 Seconds after the vehicle
has left the loop.
Permanent Presence. This feature ensures detection of the vehicle will be maintained
when the vehicle is
parked over the loop for extended periods.
Pulse Relay Selection. The Pulse relay may be configured to energise on detection of a
vehicle or to energise
when the vehicle leaves the loop.
Selectable Pulse Time. This feature sets the length of time that the pulse relay will be
energised. 1 Second or 0.2 Second.
Vehicle loop detector Application:
Loop detectors are used wherever vehicles have to be detected. Like monitoring and safe guarding access ways to counting vehicles.
The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems
in car parks or activating card dispensers in car parks.
HOW TO USE ?
1--The detector must be installed in a convenient weatherproof
location as close to the loop as possible. Installation location
must choose to stay away from the heat source, it around other
devices must maintain a distance of at least 10mm (mustn't fix
cling to the cabinet). A correct loop configuration and detector
installation will ensure a successful inductive loop detection
system. Loop of several important parameters include: loop figure,
size, and turns, install methods (details as "Loop installation
guide").
2--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.
