1 Safety Precautions and Warning Notes
GBR
• The device must only be used for the purpose intended by the manufacturer.
• Store the operating instructions in an accessible location and pass it on to every user.
• Unauthorized modifications and the use of spare parts and accessories, which are not sold or recom-
mended by the manufacturer of the equipment, can result in fires, electric shock and injury. Therefore,
such measures lead to an exclusion of liability and the manufacturer will not accept liabilities.
• For the device, the manufacturer's warranty provisions in force at the time of purchase are valid. No liability is assumed for improper or wrong manuals or automatic adjustment of parameters of a unit or the improper use of a device.
• Do not open the enclosure.
• Repairs shall only be carried out by the manufacturer.
• The power source used must meet the requirements for SELV circuits and current limited power sources
in accordance with EN 60950-1.
• Connecting, commissioning, maintenance, testing and adjustment work on the traffic detector must be
carried out by qualified electricians with the relevant accident prevention training.
• Observe valid VDE regulations when handling devices that are exposed to electrical voltage. In particular,
but not limited to, these are VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711, VDE 0860, VDE 0105, as
well as the fire and accident prevention regulations BGV A3 (previously VBG 4).
• The fact that an operational indicator turns off is no indication that the unit was disconnected from the
power supply and that it is de-energized.
• All work on the unit and its installation must be carried out in accordance with the national electrical codes
and local regulations.
• It is the responsibility of users or installers to make sure that the equipment is installed and connected in
accordance with recognized engineering practice in the country of installation and relevant local regulations. Particular attention must be focused on cable dimensions, fuses, grounding, shutdown, isolation,
insulation monitoring and overcurrent protection.
• The combined operation of extra low and low voltage on both outputs of the relays is not permitted!
• The round plug corresponds to the basic insulation properties. If the relay contacts carry voltages > 48
VAC/DC as well as for all -R230 versions, the isolation of all connecting cables of the 11-pin round plug
must be designed for 230 V AC.
• The device must not be used as a safety unit in accordance with the Machinery Directive 2006/42 / EC,
the Construction Products Directive 89/106 / EEC or any other safety regulation. In systems with potential
risks, additional safety equipment is required!
2 Maintenance
The unit does not contain parts that need servicing by the installer or user.
Do not open the enclosure.

3 Functional Description
The traffic detectors VEK MNE1 and VEK MNE2 are systems for the inductive recognition of vehicles that
must be installed in control cabinets.
Properties:
• 1-channel (VEK MNE1) or 2-channel (VEK MNE2) inductive loop detector
• Compact plastic enclosure to be mounted in the control cabinet on sockets on DIN rails
• Automatic adjustment of the system after it is turned on
• Continuous readjustment of frequency drifts to neutralize environmental influences
• Sensitivity independent of loop inductance
• Fixed dwell times regardless of the degree of coverage of loops
• Frequency adjustment
• Direction sensing (only on VEK MNE2)
• Multiplexing method to avoid mutual interference of the loop channels
• LED indication of the loop conditions
• Galvanic isolation between loops and electronics
• Relay outputs
• USB-interface for the diagnosis and other adjustments
Adjustment options:
• Adjustments by means of a 8-pole DIP-switch and a 4-pole DIP-switch (only on VEK MNE2)
• two frequency levels
• Threshold of each channel in 255 steps (via 4 stage DIP-switch)
• Off hysteresis of 20-80% per channel
• Hold time 1-255 minutes and infinite per channel (via DIP-switch 5 minutes and infinite)
• Detector channels can be turned off
• Output adjustable as presence, pulse, direction signal (only on VEK MNE2) or loop failure
GBR
3.1 Vehicle Detection System
An LC oscillator determines whether a metallic vehicle is located in the loop region or not. The output of the
channel is controlled in accordance with the selected output function.
3.2 Adjustment
The adjustment of the loop channels is carried out after turning on the detector or by pressing the front button for about 1 s. After a power failure, an automatic adjustment is carried out only when the operating voltage has been interrupted for a period of at least 0.5 s. The adjustment time is approximately 1 s, if the loop is
not crossed by vehicles during this time.
Extended adjustment periods also result by external influences on the loop frequency, their causes must be
identified and eliminated.
3.3 Output Options
Depending on the selected output function, the outputs provide a presence signal, pulse signal, direction
signal (only on VEK MNE2) or loop error. The adjustment of the pulse signal can also be used to select
whether an output takes place when driving on or leaving the loop.
In addition to the inversion of the output signals, both outputs may be turned on or off individually and permanently.
3.4 Multiplex-Procedure
The connected induction loops on the 2-channel traffic detector VEK MNE2 are turned on and off in rapid
succession. Current always only flows through one loop. Mutual influence of the loops of a detector is thus
prevented. Both loops connected to a detector can operate at the same frequency.

In addition, the inversion settings of relay contacts may need to be observed!
I.e. normally open contacts may be represented as normally closed contacts and vice versa.
On the units of the version R230, all connecting cables of the 11-pin round plug must be rated at 240V. I.e.,
normally open contacts may be represented as normally closed contacts and vice versa.
When extra low voltage (e.g. 24 V DC) and low voltage (e.g. 230 V AC) are being used, it is not permitted to
mix the operation of the two outputs !

11.1 Sensitivity, On Threshold
In the range of 0.01% - 2.55% ∆f/f the sensitivity of each channel can be selected in 255 steps.
To minimize interference, the sensitivity should only be set as high as necessary. I.e. the response
threshold should be as high as possible.

Typically, the sensitivity setting is adjusted in large steps with the response threshold selected to be no higher than 640.
In applications where it is necessary to distinguish between vehicles, values of settings higher than 640 and
fine adjustments can be utilized. A large loop (e.g. 10.0 m x 2.5 m) permits selective detection of busses
when the threshold value is set correspondingly high (> 1000).
11.2 Hysteresis, Off Threshold
To avoid the busy signal dropping out from time to time, i.e. when vehicles with a high base are utilized as
articulated buses, trams, trucks with trailers, etc., it is possible to change the switching hysteresis. Uninterrupted detection of critical vehicles is then possible even at low sensitivity.

11.3 Frequency
The adjustment of the operating frequency avoids coupling effects.
Couplings may be caused by other sensors on adjacent loops or loop cables. Therefore, it is important
that two or more sensors with adjacent loops do not operate on the same loop frequency. In this case,
GBR
the minimum frequency spacing must be 10 kHz.
DIP Description
OFF Low
ON High High frequency
None Loop channel turned off
A flashing sequence displays the current operating frequency of the loops in kHz or it may be read out with
the service program Detector Tool. (see chapter 10.1)
It is recommended to adjust the loop of one sensor to the same frequency. The multiplexing method en-
sures that no coupling takes place between the loops of one sensor.
For loop whose inductance is outside of the recommended range (see Chapter 4), the available fre-
quency range may be limited.
Low frequency (factory defaults)
Loop channels without permanently connected induction loops should be disabled in the service pro-
gram. Otherwise, it is automatically polled whether a valid induction loop has been connected. In the
worst cases, this can lead to influence on the intact loop channel.
11.4 Hold Time
On the sensor, it is possible to set separate hold times between 1 and 255 minutes for each channel. 0
Minutes correspond to infinite hold time. If the loop of a sensor channel is covered longer than the selected
hold time, the sensor channel performs the measurement again. The existing detuning of the loop channel is
cleared.

For example, vehicles that park on the loop may automatically be removed from the calculation after the
hold time has expired by adjusting the hold time.
In addition, proper adjustment of the selected hold time can avoid permanent tripping caused by faults.

In every logic, the loop that is covered first determines the count or direction of travel. For example, if loop 1
is covered first, the output is issued and the count in direction A is performed.
The factory default setting issues the output for the direction of travel A via hardware output 1 and for direction of travel B via hardware output 2. However, the assignment of the outputs may be changed.. (see chapter 11.8)
The service program Detector Tool displays the counters. It should be noted that the counters overflow
at 65535 (216) and are cleared automatically.
The counts in the detector are not protected against loss of power!
11.12 Direction Logic
Depending on the application, different evaluation logics can be selected in the logic module.
The adjustment of the direction of logic is possible only with activated direction detection!

All logics except for the logic PB in direction 1 supply in this traffic situation miscounts since they
count on instead of off signals!
11.12.9 Direction Logics “Parking Bay”
This direction logic is used for short entries and exits. The impairment of the counting process by cross traffic
on loop 1 is suppressed in this logic. It is irrelevant whether loop 1 is placed into the through road or in the
maneuvering area.

The placement of loops depends on the direction to be expected for start-stop situations. In traveling di-
rection 1 → 2 no tailback may occur! In the direction of travel 2 → 1, vehicles are also counted correctly
in start-stop situations, but it is necessary that the vehicle gap release one loop respectively.
24 09/2015 FEIG ELECTRONIC GmbH
Manual VEK MNE1 / VEK MNE2
Logics when the direction of travel is 1 →→→→ 2
• The counting pulse occurs once both loops were completely crossed
• correct counting of single vehicles
• correct counting also when maneuvering
• Traffic jams and start-stop situations may not occur when the direction of travel is 1 -> 2 !
Logics when the direction of travel is 2 →→→→ 1
• The counting pulse occurs as soon as loop 2 is left in the direction of loop 1.
• Correct counting even with cross-traffic
• proper counting in start-stop traffic
• Correct counting also when maneuvering a single vehicle
• Maneuvering within a column must not occur!
