The hold time can be adjusted with DIP-switch 6. 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.

Features: The induction loop detector VEK M2H is a system for inductive recognition of vehicles with the following characteristics: • evaluation of two loops

• detection of vehicle precence or vehicle direction • isolated transformer between loop and detector electronics A reset with calibration can be effected by changing the hold time

setting. Operation Instruction • automatic calibration of the system after power on • continuous rebalancing of frequency drifts An automatic calibration of the loop frequency starts after power on.

In case of short power cuts <0,1s there is no calibration. • usable for single place parking space supervising • no mutual influence of loop 1 and loop 2 by multiplexing • sensitivity independent of the loop inductance • presence signal by LED display 2.4 Output mode

Please read these instructions and safety information and warnings attentively before initial operation of the detector !

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 for each channel in 4 steps with DIP-switches on top of the front panel.

2.4.2 Direction output mode For direction output mode DIP-switch 7 is to be set to the right positon. Two direction logics are supported depending on DIP-switch 8.

2.2 Frequency adjustment

The direction pulse signal is normally used for counting systems and the direction pulse signal for gate and barrier controls.

The operation frequency of the detector can be adjusted in two steps with DIP-switch 5.

At the examples in the next column the operation principle of the direction logic is explained. The direction signal is output via the relay of the first covered loop i.e. signaling occurs in the case of driving direction 1->2 via relay 1 and in the case of driving direction 2->1 via relay 2.

frequency DIP-Switch 5low high

In case of failure of one loop during direction output mode the detector operate in presence output mode independed of the setting of DIP-switch 8.

The permissible frequency range is 30kHz to 130kHz. The frequency depends on the loop inductivity (depending itself on: loop geometry, number of loop turns and loop lead) and the adjusted frequency step.

3 Outputs and LED 3.1 Operating principle of the relays In standard configuration both relays operate in the closed-circuit current mode where the break contacts are led onto the connections. The operating principle of the relays can be changed according to the following table. For this modification, the detector housing must be opened carefully. Attention! Static sensitve components are on the board. During works on the open device precautions are to be taken. Do not touch components or connections on the board. There is no guarantee in case of defects by inappropriate processing!

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 10kHz position of the frequency value will be indicated. For every 10kHz frequency value the green LED flashes once. After a break of 1sec the 1kHz position is displayed in the same manner. If there is value of ‘0’ in the 1kHz position there will be displayed 10 flashes. The flashes for 1kHz position are a little bit shorter than for the 10kHz position.
