PRODUCT OVERVIEW
The SEA vehicle loop detector is compatible with most gate operators. The SEA may be used in Center, Safety and Exit
loop positions. The display feature makes set-up easy by displaying the optimum sensitivity setting required to detect a
vehicle positioned on the loop. Ten sensitivity settings allow for fine adjustment of detection level. A
PULSE/PRESENSE switch allows configuration of output relay for presence or one second pulse on entry operation.
Four frequency settings provide flexibility in preventing crosstalk in multi-loop applications.

OPERATION
Power up
Upon power up the detector initializes by automatically tuning to the loop. The green LED indicates that the detector is
powered and operational.
Frequency setting
The operating frequency of the loop is a function of the specific loop inductance and DIP switch settings 3-4. The
primary purpose of the frequency setting is to allow the installer the ability to set different operating frequencies for multi-
loop installations, recommended to prevent crosstalk/interference from adjacent loops. After changing the frequency
setting, press the Frequency Count switch to re-initialize the detector. To check the operating frequency of a loop refer
to the Frequency Count section. To determine whether crosstalk between adjacent loops is occurring, refer to the
Sensitivity Display section.
Sensitivity Display
The sensitivity display simplifies the installation process by displaying the sensitivity setting required to detect a vehicle
on the loop. To use this feature, observe the display while a vehicle is moving into position on the loop, note the number
displayed, then adjust the sensitivity setting (rotary switch) to the displayed position.
During normal operation, when a vehicle is not on the loop, the display is blank. The effects of crosstalk or other
interference can be observed on the display when the loop is vacant. Interference or crosstalk will cause the display to
indicate a level, typically 8 or 9. It may be necessary to observe the display for a minute or so to see this effect. Change
the frequency setting to prevent crosstalk.
Sensitivity setting
The 10-position rotary switch allows for precise adjustment of detection level. The sensitivity level increases from
position 0 thru 9 with position 0 being the lowest sensitivity. Typical applications require a setting of 3 or 4. The sensitivity
display simplifies the installation process by displaying the sensitivity setting required to detect a vehicle on the loop.
To use this feature, observe the display while a vehicle is moving into position on the loop, note the number displayed,
then adjust the sensitivity setting (rotary switch) to the displayed position.
Frequency Count / Reset
Press the Frequency Count switch and count the number of flashes on the red LED. Each flash represents 10kHz. To
help to prevent crosstalk when multiple detectors are used for adjacent loops, perform a frequency count on each
detector to confirm the operation frequencies are different. Following a frequency count cycle, the detector re-
initializes.
Automatic Sensitivity Boost
The Automatic Sensitivity boost causes the sensitivity to increase following initial detection. This feature is useful to
prevent dropout when detecting high-bed vehicles. The sensitivity returns to its normal setting after the vehicle exits the
loop. Decimal point on the display indicatesASB on.
Output Relay
The pulse/presence switch allows the output relay to be configured for presence or one-second pulse on entry
operation. When set to pulse operation, the display cycles through “P...U...L...S...E” repeatedly to indicate that the
detector is set for pulse operation. When set to presence, the output relay remains activated while the vehicle is present
on the loop.

REALISATION OF THE SENSITIVE ELEMENT (FIG. 1)
The detectors are suitable for coils made up with an insulated copper wire with a cross-section of at least 1.5 sq.
mm. Preferably use twisted copper wires with at least 20 twists per metre to connect the detector to the coil.
Jointing in the coil wires and in the twisted cable is not recommended. If the wires used for the twisted cable are
especially long or in proximity to other power cables, shielding of said wires is recommended. Earthing of the shield
should only be made at the extremity of the detector.
Excepting special cases, the detection coils should be rectangular. Install with the longer sides placed at right angles in
the direction of vehicle movement. These sides should ideally be kept at a meter one from the other. Coil length is a
function of the width of the road surface to be monitored. A distance of no more than 300 mm is recommended between
the coil and each edge of the road surface. For coils running over a perimeter of more than ten metres two wire windings
are normally employed, while for coils with a lower perimeter three or more windings are required, and four windings are
required for coils with a perimeter below six metres.
All permanent coil components must be secured to the road surface in appropriate grooves made using masonry
cutting tools or the like. A cross-cut at a 45° inclination must be made at the circuit angles so as to prevent the risk of the
coil cable being damaged in proximity to the apex of the right angles.
Nominal groove length: 4 mm.
Nominal groove depth: 50 mm.
The coil-detector connection cable must also be laid in an appropriate groove running from one of the circuit angles
along the circuit perimeter to the road surface edge. To ensure wiring continuity between the coil and connection cable
allow for a long enough lead to reach as far as the detector before inserting the cable inside the coil groove. After laying
the required number of wire windings in the groove along the coil perimeter, route the wire towards the road edge
through the connection cable groove.
It is advisable that connection cable length not exceed 100 metres. As coil sensitivity diminishes proportionally to
connection cable length the latter should be kept as short as possible.
Coils are secured to road surface by means of a quick-drying compound containing epoxy resin or asphalt mastic
applied hot.
