1 lnstallation lnstructions
The LD01 is a dual channel microprocessor based detector designed specifically for parking and vehicle
access control applications.The primary function of the detector is to detect vehicle presence by means
of an inductance change caused by the vehicle passing overa wire loop buried under the road surface.
The various modes are selected by changing the position of switches on the front of the unit. The
detector oscillator is multiplexed to eliminate any possibility of crosstalk between the loops connected to
the detector. The switches allow for different loop frequency settings, sensitivity settings and
modesettings.
The unit has a number of initial selectable options for configuration of the relay outputs.
The LD01 provides visual outputs ( LED) on the front of the enclosure and relay change-over contacts at
the 11 pin connector at the rear of the enclosure. The power LED indicates that the unit has been
powered. The channel status LED's below indicate that a vehiele is present over the loop and when there
is a fault on the loop. The Presence relays are normally fail-secure and will close on a vehicle detector
loop failure but not ifthere is a powerfailure.

3.3 Automatic Sensitiviti Boost
Automatic sensitivity boost is a mode which alters the undetect level of the detector . This mode is selected by
switch No. 7 on the front of the enclosure and is set as follows:
SW7
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 entire vehicle over the loop. When the vehicle departs
the loop and detection is lost the sensitivity reverts to the pre-selected level.
3.4 Presence Time
The presence time may be set to permanent presence orto limited presence. In permanent presence mode
the detector will continuously compensate for all environmental changes whilst there is a vehicle present over
the loop. In limited presence mode there will be a finite time that the detector will remain in detect. This time
is dependent on the change of inductance that the vehicle caused. The presence mode is set with switch No. 8
and is set as follows:
SW8
Off - Limited Presence
On - Permanent Presence
3.5 Reset Switch
The detector automatically tunes to the inductive loops connected to it when power is applied, whether on
initial installation or after any break in the power supply. Should it be necessary to retune the detector, as may
be required after the changing of frequency switch selections or after moving the detector from one
installation to another, momentary operation of the
RESET switch will initiate to the automatic tuning cycle.

While the detector is tuning, the Channel LEO will indicate the "mode" status of the detector.
1) Any Channel output operating in the presence or pulse modes will come on and extinguish when the
system is tuned.
2) When the AB Logic mode is selected, the Channel LEOs will alternatively flash slow and extinguish when
the system is tuned.
lf a loop fault exists the Channel LEO will come on and flash indicating a fault. lf the fault is self-healing the
detector will continue to operate.
The channel LED will also glow whenever a vehicle is detected passing over the inductive loop.
The Power LED at the top of the unit will remain on to indicate that the unit is powered.

5 lnstallation Guide
Optimum functioning of the detector module is largely dependent on factors associated with the inductive
sensor loop connected to it. These factors include choice of material, loop configuration and correct
installation practice. A successful inductive loop vehicle detection system can be achieved bearing the
following constraints in mind, and strictly following the installation instructions. The detector must be
installed in a convenient weatherproof location as clase as possible to the loop.
5.1 Operational Constraints
Crosstalk
When two loop configurations are in clase proximity, the magnetic fields of one can overlap and disturb the
field of the other. This phenomena, known as crosstalk, can cause false detects and detector lock-up.
Crosstalk between adjacent loops operating from different detector modules can be eliminated by:
1. Careful choice of operating frequency. The closer together the two loops, the further apart the
frequencies of operation must be.
2. Separation between adjacent loops. Where possible a mínimum spacing of 2 metres between loops
should be adhered to.
3. Careful screening of feeder cables if they are routed together with other electric cables. The screen must
be earthed at the detector end only.
Reinforcing
The existence of reinforced steel below the road surface has the effect of reducing the inductance, and
therefore the sensitivity, of the loop detection system. Hence, where reinforcing exists 2 turns should be added
to the normal loop, as referred to in section 5.3. The ideal mínimum spacing between the loop and the cable
and steel reinforcing is 150mm, although this is not always practically possible. The slot depth should be kept
as shallow as possible, taking care that the feeder remains exposed after the sealing compound has been
applied.
5.2 Loop and Feeder Specification
The loop and feeder should preferably constitute a single unjoined length of insulated copper conductor, with
a mínimum rating 1SA.
Joints in the loop or feeder are not recommended. Where this is not possible, joints are to be soldered and
terminated in a waterproof junction box. This is extremely important for reliable detector performance.
5.3 Sensing Loop Geometry
Sensing loops should, unless site conditions prohibit, be rectangular in shape and should normally be installed
Page 111 Copyright©2020 ZKTECO CO., LTD. AII rights reserved.

with the longest sides at right angle to the direction of traffic movement. These sides should ideally be 1 metre
apart. The length of the loop will be determined by the width of the roadway to be monitored. The loop
should reach to within 300mm of each edge of the roadway.
In general, loops having a circumference measurement in excess of 1O metres should be installed using two
turns of wire, while loops of less than 1O metres in circumference, should have three turns or more. Loops
having a circumference measurement less than 6 metres should have four turns. lt is good practice at time of
installation to construct adjacent loops with alternate three and four turn windings.
5.4 Loop lnstallation
AII permanent loop installations should be installed in the roadway by cutting slots with a masonary cutting
disc or similar devise. A 45ºcrosscut should be made across the loop corners to reduce the chance of damage
that can be caused to the loop at right angle corners.
NOMINAL SLOTWIDTH: 4mm
NOMINAL SLOT DEPTH : 30mm TO 50mm
A slot must also be cut from the loop circumference at one comer of the loop to the roadway edge to
accommodate the feeder.
A continuous loop and feeder is obtained by leaving a tail long enough to reach the detector before inserting
the cable into the loop slot. Once the required number of turns of wire are wound into the slot around the
loop circumference, the wire is routed again via the feeder slot to the roadway edge.
A similar length is allowed to reach the detector and these two free ends are twisted together to ensure they
remain in close proximity to one another. ( minimum 20 turns per metre ) Maximum recommended feeder
length is 100 metres. lt should be noted that the loop sensitivity decreases as the feeder length increases, so
ideally thefeeder cable should be kept as short as possible.
The loops are sealed using a "quick-set" black epoxy compound or hot bitumen mastic to blend with the
roadway surface.
