Model – LD200 Series
The LD200 is a dual channel inductive loop detector designed for parking
and access control applications.
The detector is connected to an inductive loop mounted in the road
surface. When vehicles pass over the loop the detector switches on an
output.
The use of microprocessor and surface mount technology enables a large
number of functions to be incorporated into a small package. The LD200 is
compatible with most dual channel detectors on the market and is easy to
set-up and install.
Applications
Typical applications in the parking and access control environments are safety loops for barriers or gates, arming
loops for activating card dispensers, vehicle counting with direction logic.
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. (%ΔL/L). Eight sensitivity settings are available on the switches to allow flexibility in configuration.
Switch selectable Frequency. The frequency of the loop is determined by the inductance of the loop and the
frequency switch setting. If the frequency switch is on, the frequency is reduced. It may be necessary to change
the frequency to prevent cross-talk between adjacent loops on different detectors.
Selectable N/O or N/C relay output. Internal jumpers enable the output relay contacts to be configured for
normally open or normally closed contacts.
Extend Option. When switched on this feature extends the presence output relay for 2 Seconds after the vehicle
has left the loop.
Direction Logic. This feature enables the detector to give a pulse output on relay1 for a vehicle travelling from
loop1 to loop2 and a pulse output on relay2 for a vehicle travelling from loop2 to loop1. To enable this feature
switches 2 and 4 must be on, and switches 3 and 5 must be off.

Loop Installation Guide 1. The detector should be installed in a waterproof housing as close to the loop as possible. 2. The loop and feeder should be made from insulated copper wire with a minimum cross-sectional area of 1.5mm . The feeder should be twisted with at least 20 turns per metre. Joints in the wire are not recommended and must be soldered and made waterproof.
