Working Instructions - RIB ACG9064 Guia De Inicio Rapido

Loops are secured to road surface by means of a quick-drying compound containing epoxy
resin or asphalt mastic applied hot.
In the case of two contiguous loops, keep a minimum distance of at least 2 m between each.
Note: The inductive activity and hence the sensitivity of the loop detection system is reduced
by the presence of a steel reinforcement beneath the road surface. Ideally allow for a
distance of 150 mm between loop cable and steel reinforcement.

WORKING INSTRUCTIONS

RESET/CALIBRATION PUSH-BUTTON
The RESET push-button makes it possible to initialize the detector and automatically acquire
the parameters of the loop connected for correct functioning.
N.B. Making sure that there is no metallic mass on the loops, press the RESET push-button to
carry out an automatic calibration of the detector.
The RESET push-button must be pressed each time the setting of one or more dip-switches
is modified.
LED (Fig. 4)
POWER - RED LED PRESENCE OF POWER SUPPLY
This LED remains always ON when the power supply is present.
CHANNEL 1 DET - RED LED STATE OF TESTING OF THE LOOP CHANNEL 1
This LED comes ON when there is a vehicle on the loop or when the Loop is defective.
CHANNEL 1 FAULT - RED LED DEFECTIVE STATE OF LOOP CHANNEL 1
This LED comes ON when the circle of the loop is open or when there is a short circuit, and it
is used to signal when the loop is defective.
CHANNEL 2 DET - RED LED STATE OF TESTING OF THE LOOP CHANNEL 2
This LED comes ON when there is a vehicle on the loop or when the Loop is defective.
CHANNEL 2 FAULT - RED LED DEFECTIVE STATE OF LOOP CHANNEL 2
This LED comes ON when the circle of the loop is open or when there is a short circuit, and it
is used to signal when the loop is defective.
SETTING AT WORK
- Realize the connections for the undecal socket as shown in Fig. 4 and subsequently insert
the detector as shown in the same figure.
- Set up the frequency through the dip-switch 6 as shown in TABLE 1. The change of frequency
is mainly useful to avoid interference between two near loops (2-3 m); in this last case it is
necessary to set up different frequencies. As a general rule the frequency must be low for
large loop and high for small loop. In most cases, it is recommended that the frequency is
set on the LOW value (DIP 6 ON).
- Set up the sensitivity through the dip-switches 7-8-9 as shown in TABLE 1. Setting the
sensitivity allow to forbid the detection of metallic body with little dimensions such as
bicycle and motorcycle.
- Use of the sensor only for the impulsive command
DIP 2 OFF + DIP 3 ON => impulsive command at the exit 2 and when the loop 2 is engaged.
DIP 4 OFF + DIP 5 ON => impulsive command at the exit 1 and when the loop 1 is engaged.
DIP 1 OFF => the time for the impulse lasts 0,2 s
DIP 1 ON => the time of the impulse lasts for 1 s.
- Use of the sensor only with presence of vehicle
DIP 2 OFF + DIP 3 OFF => for Channel 2
DIP 4 OFF + DIP 5 OFF => for Channel 1
the correspondent exits will remain permanently activated until the vehicles is not leaving the
perimeter of the loop.
DIP 10 ON => there will be a 2 s delay in the switching off of the exits.
- Be sure that there is no metallic mass on the loop, and press the RESET push-button to carry
out an automatic calibration of the detector.
- Carry out sensitivity tests with the various types of vehicles that the device must detect. If
necessary, vary the setting of DIP 7-8-9 until the desired sensitivity level is obtained.
In most cases, it is recommended that the frequency is set on the LOW value (DIP 6 ON).
DIP 5 ON => "SENSITIVITY AMPLIFIER". This feature is used to increase the sensitivity in order to
keep the detection contact active even in the case of very high vehicles or during
the passage of a tractor with a trailer.
FEATURE OF DIRECTION
DIP 2 - DIP 4 - DIP 5 ON
This feature allows to have an impulse
on the exit of Channel 1 for a vehicle
that passes on loop 1 and after on
loop 2.
DIP 2 - DIP 3 - DIP 4 ON
This feature allows to have an impulse
on the exit of Channel 2 for a vehicle
that passes on loop 2 and after on
loop 1.
COMMAND AFTER DISENGAGING THE LOOP
DIP 2 ON - DIP 3 ON => there will be an impulse on exit Channel 2 after disengaging loop 2.
DIP 4 ON - DIP 5 ON => there will be an impulse on exit Channel 1 after disengaging loop 1.
DIP 10 ON => there will be a 2 second delay of the impulse for the exits.
Attention: It is possible to change the status of the contact of the exits from N.O. (normally
open) to N.C. (normally closed). To carry out this modification, the jumper-bridges
near the relays, inside the magnetic detector must be set differently. To do that
open the magnetic detector, remove the pcboard and manage the jumpers near
the relays.
