Features:
The induction loop detector RG01 is a system for inductive
recognition of vehicles with the following characteristics:
Isolated transformer between loop and detector electronics
Automatic calibration of the system after switching on
Continuous rebalancing of frequency drifts
Usable for single place parking space supervising
Sensitivity independent of the loop inductivity
Presence signal by LED display
Potential free relay contacts for presence and pulse output
Pulse output while leaving the loop
Signalling of loop frequency by LED
Loop connection plug-in for diagnosis
For planning and installation of loops please note our manual "detection
of vehicles with the induction loop d
2 Setting options
2.1 Sensitivity
The setting of the sensitivity calls the electronics to a value of frequency
deviation which a vehicle must produce for setting the output of the
detector. The sensitivity can be adjusted in 4 steps with the two DIP-
son top of the front panel.
sensitivity step DIP-switch
1 low (0,64 % f/f)
2 (0,16 % f/f)
3 (0,04 % f/f)
4 high (0,01 % f/f)
2.2 Hold time and Reset
The hold time can be adjusted with DIP-
At the completion of hold time it will be displayed "free loop" and the
detector calibrates automatically. The hold time starts with the
occupation of the loop.
hold time DIP-swi
5 minutes
infinite
An automatic calibration of the loop frequency will be done by the
detector after switch-on of the power supply. In case of short power cuts
<0,1 s there is no calibration.
A reset with calibration can be effected by changing the hold time
setting.
2.3 Operation principle of the presence relay
The detector has one relay for presence output and another relay for
pulse output each with a potential free contact. The operation principle
of the presence relay can be changed with the DIP-

contact normally open
2.4 Frequency adjustment
The operation frequency of the detector can be adjusted in two steps by
the 3-pole connection jack in the front panel. The permissible frequency
range is 30 kHz to 130 kHz. The frequency depends on the loop
inductivity (depending itself on: loop geometry, number of loop turns
and loop lead) and the adjusted frequency step.
upper position = high frequency
lower position = low frequency
3 Outputs and LED
3.1 Contact mode of the relays
The following table shows the state of the relay contacts depending on
the detector mode.

loop failure open close open
power off close close open
In case of a loopfailure the detector checks the loop condition cyclically
and continues automatically after elimination.
3.2 LED signals
The green LED signals that the detector is ready for operation. Via the
red LED, the activation of the relays output is announced depending on
the occupation status of the loop.

3.3 Output of loop frequency
Approx. 1 sec. after calibration of the detector the loop frequency will be
displayed by pulse signals of the green LED. Firstly the 10 kHz position
of the frequency value will be indicated. For every 10 kHz frequency
value once. After a break of 1 sec the 1 kHz
position is displayed in the same manner. If there is value of '0' in the 1
kHz position there will be hes for 1 kHz

Example for 57 kHz loop frequency:
5x 10 kHz 7x 1 kHz

4 Safety information and warnings
The device should only used for the applications described by the
manufacturer.
Please keep this operation instruction always accessible and hand it
over to every user.
he device, use of repair parts and
supplementary equipment which are not sold or recommended by the
manufacturer can cause burning, electric shock and injuries.
Therefore the manufacturer has no liability and this excludes all
demands of warranty.
The warranty regulations of the manufacturer are valid in the version
of the purchase date for that device. There is no liability for not
suitable, wrong manual or automatic adjustments also regarding no
suitable applications of the device.
Repairs may only made by the manufacturer.
The he requirements for SELV and
limited power sources according to EN 60950-1.
All connections, the start-up, maintenance, measurements and
adjustment operations to the detector have to be made from electrical
specialists who have special know-how in the prevention of accidents.
For the use of devices which have contact to electrical power, please
pay attention to the valid security instructions and all prevention
nd accidents.
All operations with the device and its placement have to be done in
accordance with national and general electrical instruction orders.
The user is responsible for an installation, which has conformity to all
technical rules in the country where the device is mounted, and also
to all regional valid orders. For that the dimension of cabling, fuse
nection, isolation
controlling and the protection for overload current have to be regarded
in detail.
The detector can not be used as a security device regarding to the
security instructions of electrical machines. Using in systems with high
danger potential it is necessary to include additional protection
devices!

7How to make the loops
The loops must be constructed at least 15 cm from fixed metal objects,
at least 50 cm from moving metal objects, and at no more than 5 cm
from the surface of the definitive flooring.
Use a normal single-pole 1,5 mm² diameter cable (if the cable is buried
directly, il must be double insulated).
Make a loop, preferably square or rectangular, using a PVC raceway
or making a chase in the floor as shown in the figure at the side
(corners should be cut at 45° to prevent the cable from
fracturing). Lay the cable, with the number of windings indicated in the
table.
The two cable ends must be intertwined (at least 20 times per
meter) from the loop to the detector.
Do not make any joints on the cable (if this is necessary, solder the
conductors and seal the joint with a heat-shrink sheath) and keep it away
from mains power cables.

fromto 4 m.
