Page 7: Product Description
2 Product description General The SW2224 is a classification detector operating with two induction loops per lane according to ASTRA-SWISS-specifications. The SW2224 classifies the vehicles into the ASTRA-SWISS-classes SWISS10, SSSVZ vehicle classes or car-similar / HGV-similar). When using ASTRA-SWISS loops, the classification meets the definitions of ASTRA. - Page 8 The configured parameters are stored in a non-volatile memory (EEPROM). ATTENTION The loop detector SW2224 is solely designed for use by qualified personnel trained in dealing with traffic detection equipment. Improper use of the SW2224 may result in unpredictable behavior of the systems controlled by the detector.

Page 13: Operating The Sw2224 With Loopmaster
4 Operating the SW2224 with LoopMaster General The SW2224 is operated via service interface on the front by means of the LoopMaster operating program installed on a PC or laptop computer. The detector is connected directly with the COM port of the PC or alternatively via USB port and standard COM-USB adapter. - Page 14 LC22: 2 loop systems with 2 double loops each Opposite to detectors for traffic light systems, the SW2224 is normally used as double loop detector, i.e. in order to function a loop system with 2 inductive loops arranged successively is necessary.

Page 15: Display And Operating Elements At The Front Panel
The reception and transmission processes of the RS485 data bus interface are indicated at the RXD and TXD LEDs for the reception and transmission direction of the SW2224 . The FCT LED flashes with a frequency of 1 Hz during normal operation of the detector. With activation of MASTER-SLAVE synchronization, the flashing frequency during normal operation is reduced to 0.5 Hz. - Page 16 In the standard Version of the des SW2224 (2 double loop systems K1 / K2 and K3 / K4), the parameter frequency range can additionally be adjusted at the DIP switch on the front. For most applications this is the only adjustment to be made and there are no further adjustments necessary e.g.

Page 17: Alignment And Error Diagnosis
There must be no extended vehicle passages during the alignment. If a convoy of vehicles passes during alignment, the SW2224 attempts to adjust to the gaps between the vehicles. There are no vehicle detections possible during the alignment. After the alignment, the channel is always in an "undetected"... - Page 18 After troubleshooting, an alignment of all channels or a reset of the SW2224 with subsequent alignment of all channels can be initiated using the pushbutton on the front panel in order to restore correct functionality.

Page 19: Automatic Calibration And Control Of Vehicle Detection
Automatic calibration and control of vehicle detection The SW2224 is delivered with standard parameter values optimized for the permitted loop and feeder cable configurations. In order to further optimize the single vehicle detection, important characteristic values e.g. norm value and switch-on threshold resp. sensitivity for the connected loop / feeder cable configuration are permanently and automatically evaluated and stored non-volatile in the EEPROM. - Page 20 3 this is 1.45 % and 1.55 % as norm values of the two loops. Further reasons for bigger differences are different installation depths, number of windings or loop dimensions. www.swarco.com SWARCO TRAFFIC SYSTEMS GMBH, Niederkircher Straße 16, D-54294 Trier, Germany T. +49-651-81002-0, F. +49-651-81002-999, E. detection@swarco.de 20/39...

• are settings which apply to the entire device (refer to section 7.2) In addition to the user-adjustable parameters, the SW2224 also provides diagnostic data, which can be displayed in the LoopMaster. These values cannot be directly modified but result from the parameters (e.g. frequency from configured frequency range), are determined during operation (e.g. - Page 22 (see also chapter 6.2). The oscillator of the SW2224 is designed in such way that, when using loops with inductan- ces within the recommended range, all frequency ranges can be used (see chapter 8.1).

Page 24: Loop Type And Loop Distance
7.1.3 Loop type and loop distance The parameter loop type is of great importance for the classification. The SW2224 uses separate classification algorithms for each loop type resp. loop length because identical vehicles generate different vehicle patterns with different loop lengths. Thus, for each loop length a separate vehicle pattern database is used in order to reach a very high classification accuracy. -
Page 25: Detection Of Wrong Way Drivers
(e.g. classification and speed measurement). Therefore, the sensitivity cannot be changed. The SW2224 has an automatic sensitivity adjustment and very short measurement times in order to ensure optimum single vehicle detection also at high speeds. -
Page 26: Hold Time
This function is deactivated with the value 0. On activating the function "Automatic alignment case of error", a new alignment attempt is cyclically (1 min) initiated. www.swarco.com SWARCO TRAFFIC SYSTEMS GMBH, Niederkircher Straße 16, D-54294 Trier, Germany T. +49-651-81002-0, F. +49-651-81002-999, E. detection@swarco.de 26/39... -
Page 27: Noise Threshold
After the LED turn-off time has elapsed, the LEDs are switched off. Briefly pressing the pushbutton or communicating via the service interface reactivates the LEDs. The value 0 deactivates the turn-off function. www.swarco.com SWARCO TRAFFIC SYSTEMS GMBH, Niederkircher Straße 16, D-54294 Trier, Germany T. +49-651-81002-0, F. +49-651-81002-999, E. detection@swarco.de 27/39... -

The extended channel flags are a supplement to the channels flags described in chapter 7.1.9.
