Operating principle
The following shows the simplified principle of a metal search detector, with an example of a conveyor belt
application. The shape and look of your application may differ, but the principle is the same.

a) Metal detector
b) Electromagnetic field
c) Product line

Metal detection

1. The seeker head creates and evaluates an electromagnetic field with the help of transmitter and receiver
coils.
2. If a metal body enters the field, the signal indication display deflects in one direction.
see too chapter Operation
3. If the metal body leaves the field, the display deflects in the opposite direction.

If both switching thresholds are reached, metal is detected.

If metal is detected, several outputs, depending on your configuration, can be used to query the events: At
least one Relay and a 24V (output A1) are available for your queries.

General notes on metal detection

Electro-magnetic short circuits

Certain metal frame constructions in conveyor belt frames (see drawing) and suspensions (e.g. castors, cross-
bars, adaptor plates) can act as an electro-magnetic loop in the vicinity of the metal detector, affecting the
magnetic field of the metal detector. Closed conductive loops must either be welded tight, or interrupted, e.g.
with unilateral isolation.
Example:

a) Conveyor belt frame

b) Conveyor belt motor
c) Isolation

1. If the cross-bar is welded tight, the electro-magnetic effect on the metal detector remains constant,
and does not have an adverse effect on the metal detector’s magnetic field.
If the cross-bar is merely screwed on, a constant conductive connection cannot be guaranteed. The
metal detector is affected adversely due to the changing conductive loop.
2. Castors and moving parts that constitute a conductor loop need to be isolated unilaterally (see 3), so
that the conductor loop is interrupted.

Electrostatic discharges

Prevent at all cost electrostatic discharges to the metal detector and surrounding construction components
using the appropriate earthing. Electrostatic discharges can cause false signals and at worst, destroy the
analysis electronics.

-12-
Differences in sensitivity within the outlet opening

Please note, that the detector coil does not create a homogeneous electromagnetic field. As a consequence,
differences in sensitivity occur in the outlet opening. The least sensitive part of the detector is in the middle
of the outlet opening.

Sensitivity distribution taking the example of a

C-coil (1) and a CR-coil (2):
a) Area of highest sensitivity
b) Area of lowest sensitivity

Sensitivity differences of different metal types

Please note, that different metal types influence the electromagnetic field to a different degree. Please read
the metal-type dependent maximum sensitivity degrees in the data sheet.

Position-dependency of the metal parts

Metal detection can be dependent on the position and orientation of the metal part, depending on the shape
of the metal part. The maximum sensitivity values of the data sheet are tested with ball-shaped test parts.
Generally speaking, all metal parts that have at least the same diameter as the balls used for the data-sheet
values can be detected with certainty, irrespective of position and orientation.

Testing at regular intervals

Normally, errors of the detector itself are recognized by the self-monitoring system. However it cannot be
excluded that errors may occur which are not detected. Changes in the environment of the detector (e.g. new
machines) can influence the function of the detector.
For this reason, settings and function of the metal detector must be checked at regular intervals with suitable
test equipment.
see chapter Adjustment Operating level QM Detector test

Environmental and weather influences

The metal detector has to be protected against environmental and weather influences (direct sun, wind,
frost). The detector has to be especially protected from direct or indirect insulation when heating up is above
the allowed temperature. High surface temperatures can lead to false detections and destruction of the metal
detector in the worst case. A suitable protection device must therefore be provided (do not use metal walls or
roofing covers made from metal!)

Actuation
2

General
It is our company’s goal to ship the metal detector to the customer with as many pre-configured settings as
possible. If the machine is shipped with factory default settings, it should be noted, that the factory defaults
are the best possible compromise between maximally attainable detection precision and lowest possible
sensitivity to interference. The data sheet sensitivities are achieved with sensitivity settings between 90 and
100%.
In order to adjust the settings according to one’s own requirements, the following plan will outline how to go
about setting up the machine. Only the steps are explained, for a thorough explanation of the menu items,
you should consult the operating manual.

Safety procedures before taking the device into operation

Before actuating the metal detector at least the following parts of the device must be
checked:

• Is the device damaged anywhere?

• Are the electric ports and mains undamaged ?
• Are all protective covers fitted and free of damage?
• Are all pneumatic supplies and mains undamaged (if installed)?

The device can start if everything is perfect.

-15-
Actuation manual

Clean the metal detector

If the product is not allowed to have contact with foreign matter, all surfaces having contact with the product
must be cleaned before start-up operation.
Please follow the safety instructions!
see chapter Maintenance and cleaning Cleaning

Assemble metal detector

Assemble the metal detector according to the information provided in the chapter „Assembly“.
see chapter Assembly

Connecting the 24V switching exits and relays

Connect the 24V switching exits and relays as needed. Please follow the indications in the chapter Set-up.
see chapter Assembly Connection

Connect power supply

see chapter Assembly Connection Supply voltage

Now your metal detector is fully assembled and connected.

All further instructions refer to the most important settings, that should be adjusted at your detector in order
to ensure perfect operation of your device while maintaining the highest possible sensitivity.

Switch metal detector on

Having assembled the detector mechanically, as a first step it is taken into operation. Under this condition
the detector is only subject to external influences (peripheral disturbances). If at this point faulty responses
are triggered, you have to try and find the source of the disturbance and to correct the error. For this switch
off all machines (motors, actuation, etc.) in the direct surroundings of the metal detector so that the metal
signal of the metal detecting device stays within the triggering range. As a next step the device is taken again
into operation step by step.
After each step control the measure signal in order to locate the disturbance, that causes an increased noise
level. If a noise suppression is not possible, you can only reduce the sensitivity until there are no more
incorrect triggering.
see chapter Adjustment Operating level 1 Sensitivity

-16-
Activate production- and transporting device
As a next step the production and transporting device is taken into operation without loading products. In
this state the influence of the transporting device on the metal detector becomes evident. Here also applies: If
there should be incorrect triggers try to locate the cause of the disturbance and suppress it. For this, take the
production line into operation as mentioned above, step by step.
Contrary to peripheral disturbances that often need very high efforts to suppress them in this case a solution
should be easily found.
Temporarily the sensitivity can be reduced until there are no more incorrect triggerings.
see chapter Adjustment Operating level 1 Sensitivity

Start complete production line

Now start the complete production line. For the set-up-step you should, if possible, use only metal-free
products. The further Stepps depends on the current situation. If there are metal events while a metal-free
product is passing through the coil, you should continue with the following point, otherwise you may skip
the following point.

„Learn product“
Your product is conductive and therefore influences your metal detector without metal being existent in your
product.
Follow the instructions as in „Adjustment Operating level 2 Learn product manual“, in order to
counterbalance the “product effect”
see chapter Adjustment Operating level 2 Learn product

Optimize sensitivity settings

Note:
The higher the sensitivity is set, the higher the susceptibility for incorrect triggering.
see chapter Adjustment Operating level 1 Sensitivity

Change name of the product (recommended)

Now you can enter a name for the product. This is most important if you use several different products or
product groups in connection with the metal detection device.
see chapter Adjustment Operating level 2 Parameter set

Adapting the reject parameter(if need be)

see chapter Adjustment Operating level 2 Reject parameter

-17-
Adjustments finished
If you do not wish to use the machine for any other products, you can skip the next point.

„Change products“
You can save up to 50 different products (parameter sets). In connection with the name sensitivity and
separating time are saved. In order to adjust settings for a new product, you have to change product.
see chapter Adjustment Operating level 2 Parameter set
Repeat the points “Start complete production line” to „Change products“until all products/parameter
sets that are operated together with the metal detecting device are configured.

You now have set your metal detection device at optimum

level.
All further setting possibilities serve for adjusting the metal detection device to the production process and
for implementing functions and evaluations adapted to applications.
An overview of all of your metal detection device’s functions is provided in chapter „Adjustment“.
see chapter Adjustment

-18-
Assembly
3

Please note when assembling your detector

the following assembly instructions in
order to ensure perfect operation.

Installation guidelindes

Electronics
Connect the metal detector to a clean, constant voltage power supply.
Voltage fluctuations can cause false trippings. Therefore, a constant voltage transformer (AC line
conditioner) is recommended. In order to check if false tripping is caused by voltage fluctuations you can
temporarily supply the metal detector with a UPS (Uninterruptible Power Supply, direct, independent power
supply as used for Computers). Please, do not forget to plug off the input cable of the UPS to separate it from
the AC line.

Do Not install the control panel near MCC's or control panels of other machinery.
Stray fields of motor lines and high power cables can trigger faults. Be especially aware of frequency
inverters and DC Drives as they can emit high frequent electromagnetic fields that might cause false
trippings of the metal detector. Please follow the guidelines of the manufacturer of the motor drive.
Especially take care of using screened motor cables, AC Filters and make sure that the ground connection is
correct.

Run the transmitter and receiver cables to the metal detector separately from live wires.
The detector cables can catch noise, especially when they are close to motor lines or high power cables. To
improve the screening of the cables, solid metal conduits with a good ground connection (best welded) are
recommended. Please do not connect the conduits to the metal detector or at least use plastic fittings when
connecting flexible conduits to the cabinet or transmitter and receiver boxes of the metal detector. Be aware
of ground loops. Both cables can be run in the same conduit.

-19-
Do not disconnect the metal detector from the power if possible.
A constant, uninterrupted power supply enables more sensitive adjustments and prolongs lifetime of
electronic components. Powering the unit on and off causes it to recalibrate (8 seconds) during which time
metal will not be detected.

When welding at the construction where the metal detector is mounted, disconnect the metal detector
from the power supply and do not use the control panel mounting surface as a ground.
Warding near the metal detector will lead to false trippings.

Vibration less using of the control panel

Mount the control panel on a vibration free surface. Vibration can cause premature electronic component
failure.

If the electronics casing is mounted onto other machine parts, there is a danger of causing an earth
connection loop, which can lead to malfunctions.
In such cases, the electronics casings should be isolated (suitable plastic panes and isolating materials can be
found among spare parts for installation).

All cables must be shielded.

The shield must be connected face-to-face on the housing; ideally by means of an EMC screw.

-20-
Detector general
Be careful when you have more than one metal detector in operation!
If several metal detectors are installed in immediate proximity, they might Interfere with each other when
running at the same detection frequency (frequency overlaps).If we know in advance that you have more
than one detector in operation, we do already adjust the detectors to different frequencies. Should there be
frequency overlaps, you can adjust one detector to side frequency.
see chapter Adjustments Operating level 2 Frequency Secondary frequency

Please observe the required minimum distances. For closed tunnel detectors type C, CI and CR: minimum
distance = 10 x LH (LW for type CR), if the detectors are installed parallelly in one row. For divisible tunnel
detectors type D and single surface detectors type S: minimum distance= 15 x LH (SB for type S), if the
detectors are installed parallelly in one row. The minimum distances may be lower if you work with
different frequencies. Please consult our sales or application department.
LH = Aperture Height LW = Aperture Width SB = Detector breadth

Do not install the detection coil inside a strong electromagnetic field. (especially if in the direct
surroundings of the seeker head there are strong load variations at other electronic devices).
Interferences can trigger faults. Specifically, fields lying exactly within the operating freqency of the detector
can lead to frequency overlapping and hence to false tripping.

Pay attention to the metal free zone (MFZ) of the metal detector.
Do fixed, non-moving metal parts outside the metal-free zone have little influence on the metal detector’s
function. Metal parts changing their distance to the detector (levers, swivel arms…), however, might cause
problems within the metal free zone, please use electrically non-conductive material only, e.g. wood or
plastics. Please keep in mind that the use of a plastics slide plate may promote the formation static charges.
see chapter Assembly Tips for Set-up

Vibration less using of the detector coil (all, except "VT" type).
Higher sensitivities can be attained and maintained if the operating conditions are optic mal. Ensure the coil
is mounted to a structure that is stationery at all times.

Take steps to avoid the detector cables moving back and forth.
Please fasten the transmitter and receiver cables with the aid of clips so that they cannot move. Strong
movement of the cables back and forth can lead to false triggering.

Eliminate loose metal to metal connections near or within the detection field.
Intermittent metal contact from components such as roller axles, bolted structural connections of the
conveyor frame, loose grids from access platforms or broken welds can cause false reject signals, especially
at high sensitivity settings. In order to avoid creating intermittent magnetic loop contacts, please isolate metal
parts from one another or weld them together. Bolted ground connections will not solve this problem.
see chapter Introduction General notes on metal detection

-21-
Pay attention to the maximum installation batter of the search head
You can take the maximum installation batter from the datasheet. For larger batter, please contact the
manufacturer before installing the unit.

Please clean the conveyor belt (of belt conveyors) regularly.

Metal impurities cause fault detections. Please make sure the belt runs centrically on the rollers and nothing
rubs on the belt.

Pay attention to an electrical insulated installation.

The mounting feet of the detector provide an electrical insulation, do not remove them.

Do not use anti-electrostatic (or electrically conductive) belt material.

Anti-electrostatic belts are conductive and cause an effect similar to metal in the metal detector.
Depending on the relevant application, a conveyor belt appropriate for the metal detector must be chosen.
The conveyor belt should have a so-called finger coupling. Furthermore, glue containing metal particles
must not be used for connecting the belt.

Do not touch the sensor/coil surface of the detector.

(not VT-Coil and Profi Line)
Mechanical contacts may cause detection errors. Keep the surface free of debris.

The frame must be manufactured with appropriate stability.

Loose attached parts, in particular loose transverse connecting parts such as bracing struts, bolted discharge
plates, cover plates etc. can cause considerable interference. Screwed connections should be dispensed with
entirely in this area if possible – welding is better. Insulate the parts on one side wherever screwed
connections are absolutely necessary.
Power rolls, deflection rollers and snub pulleys are also possible sources of interference, as the
electrical contact is submitted to large variations caused by damaged or bad bearings.
The same applies to swivelling belt strippers. These parts should always be insulated on one side. Please
note: Bridging bad contacts with earth band or wire will not help!
see chapter Introduction General notes on metal detection

When welding at the construction where the metal detector is mounted, disconnect the metal detector
from the power supply and do not use the control panel mounting surface as a ground.
Welding in the surroundings of the detector will trigger faults.

Tips for set-up

General
1. Metal free zone
2. Metal detector
3. Belt frame
4. Conveyor belt
5. Sliding plate
6. Sensor surface

The product, conveyor belt and sliding plate must not touch the sensor surfaces (this is not true for
VT/SL coils ).
The sliding plate (plastic or wood) must have the correct size or supports, so that it cannot touch the sensor
surface, even if the conveyor belt is fully laden (This also counts for the conveyor belt when backing up in
the coil). Distance: roughly 10 mm. It is recommended to use wood, to avoid the generation of electrostatic
charges.
The proper choice of conveyor belt, suitable for metal detectors, depends on its use. The conveyor belt
should have a so-called “finger coupling”. Also, the belt coupling must not be fixed with glues containing
metal.
If the construction space of the conveyor belt allows, you may choose a longer metal-free zone.

be found in the chapter “Access Codes”.
Having entered the four-digit code number (2), you have to
acknowledge using “OK” (3). Subsequently, you are taken to the
desired operating level. (Operating level 1 in this example)

Here you can select the various menu items (4) (e.g. the menu
item “sensitivity”).
The “Signal” button takes you back to the main menu.

Upon selecting a menu item, you may change the parameter

using the number block or the slide control. The new value is
used once you acknowledge with “OK”. You are then taken
back to the next operating level above the menu item (here
“Operating level 1”).
“Cancel” takes you back to the next operating level above the
menu item (here “Operating level 1”), and the changes you
made to the parameters are discarded.

Sensitivity
The metal detector is set to optimal sensitivity by factory default (unless a different setting has been agreed
upon previously). The factory default settings are the best possible compromise between maximally
attainable detection precision and the lowest possible sensitivity to interference. Data sheet sensitivities are
attained with sensitivity settings between 90 – 100%. When setting up the machine, please make sure you
use a metal part (e.g. a test object), which you will have the machine detect. Later, during operation, metal
parts of the same size and larger metal parts are ejected – not smaller ones. In case you do not have
appropriate metal parts, you can obtain standard-sized test objects on test rods.
Attention:
The higher the sensitivity, the higher the susceptibility to erroneous ejections.
To optimise the sensitivity setting, you should use the following pattern:
1) Take the smallest metal piece you want to detect and run it through the metal detector (standard test
pieces can be abstained from the manufacturer)
2a) Metal detection
Reduce the sensitivity in small steps until the smallest metal piece is no longer detected, and increase the
sensitivity setting by a safety reserve of 5 %.
2b) No metal detection
Increase the sensitivity in small steps until the smallest metal part is finally detected, and increases the
sensitivity setting by a safety reserve of 5 %.
Please note:
The display of the sensitivity setting in percent does not indicate the absolute sensitivity of the machine.
Rather, the sensitivity setting within a defined range are defined here. This means that even at the minimal
setting of 1% sensitivity, the machine will still exhibit basic sensitivity.
Please observe the following for metal detectors with test aperture:
The metal sensitivity in the test aperture may vary from the stated metal sensitivity of the detector. The test
aperture is designed only to verify the functions of the detector, it is not designed to indicate the kind or
size of metallic contaminant which can be detected.

Charge number (optional)
The menu item charge number is only displayed if it has been activated.
Here a new charge number can be entered. Via the charge number, different customer orders, e.g., are
recorded separately from each other in the printer protocol.
see chapter Adjustment Operating level QM Printing Protocol print-out

Test diverter (optional)

The menu item Test diverter is only integrated in machines with separating mechanics.
4 Line Display: Adjust the menu item Test diverter to „ON“ to effect a test separation of your separating
device.
After the test separation has been carried out, the Note 26 is displayed for ca. 15 seconds. The note informs
you about the reaction time measured when switching the separating mechanics on and off.
Attention:
• A function test of the separating mechanism must be carried out once per day
• If the machine is in error mode, the function Test diverter is locked for security reasons.

Empty out collector bin (optional)

The Empty out collector bin menu item is only displayed, if Cumulative ejection time has been activated
in operating level 2.
If you wish to empty out collector bin before it is full, this menu item will re-set Cumulative ejection time.
see chapter Adjustment Operating level 2 Reject parameter Cumulative ejection time

Metal counter
The menu item metal counter shows the number of metal messages issued by your metal detection device.
On operating level 2 the metal counter can be restored to zero.
choose Operating level 2 Metal counter

Start detector test

You can start the detector test manually here. You can set the time duration (test timeout) in which you must
perform the detector test and additional configurations in the detector test menu item.
see chapter Adjustment Operating level QM Detector test

Operating level 2

Learn product
The learning process is necessary if when metal-free products are transported, the message „metal“ occurs.
This process is also called product compensation i.e. the metal detection device is set in a way that the
influence of the product is suppressed.
Note:
During the learning process only metal-free products may be transported!

The learning procedure can either be carried out automatically (recommended) or manually.

Learn product automatic

After starting the machine, the automatic learning procedure will be executed by means of two product
passages.
During the test runs, please only convey metal-free products.
The number of product passages may increase depending on the product as well as the product`s condition.
After successful "learning" the learning procedure will be finished automatically.
If the automatic learning procedure was not stopped successfully, you should learn the product manually and
reduce sensitivity, if needed.

Compensation optimisation

These settings are automatically accounted for during automatic product learning.

Off: If trigger limits are still exceeded with the current learning value, the sensitivity should be
decreased.
Automatic: In the case of automatic optimisation, the product is optimised for the sensitivity which is
currently set.

Learning angle / learn product manual (in case of text display)

The learning angle is he value with which the compensation is being carried out at this point.
The optimum learning value is achieved when the measurement signal in the display is as smooth as
possible. If the trigger limit is still being exceeded even with optimum learning values, the sensitivity must
be reduced.
The value set here refers only to the properties of the product material and not the product quantity.

-54-
Reject parameter
Reset mode

Depending on you application, you can reset a metal detection either automatically or manually. If no
particular requests have been given by the customer, the metal detectors will be supplied with reset mode
„automatic“.
• Reset mode automatic:
Time-controlled metal notification is set for automatic ejection of metal-contaminated products. You may set
the delay and duration of the metal notification in the menu “Operating level 2 Reject parameter”
• Reset mode manual:
With this reset mode, you can only delay the metal signal, e.g. to remove the metal part from the opening.
The machine is restarted by resetting the metal detector at the display or with an external reset button.

Reject delay

The set value is a time shift between metal part detection in the seeker coil and the signals at the exits. The
metal delay can be set independently of the reset mode.
see chapter Adjustment Operating level 2 Separating parameter Reset mode
The reject delay can be chosen from 0 (off) to 30 seconds.

Reject time (optional)

Reject time is the time, within which the rejection mechanism remains in the offal rejection position once
metal has been detected.
The Reject time can be chosen from 0.1 to 10 seconds.
You can find the optimal setting, by starting with an absolutely safe ejection time, and reducing
the value step by step. The first time that the metal part is not rejected, you increase the value,
adding a further safety leeway.

-55-
Cumulative ejection time (optional)

The Cumulative ejection time menu item is only displayed if Reset mode automatic has been selected.
The menu item Cumulative ejection time is used to monitor the collector bin and prevent it from flowing
over. The Cumulative reject time is calculated as follows:

Reject time x Number of metal events = Cumulative ejection time

An example:
The Reject time is set to 1 second.
see chapter Adjustment Operating level 2 Separating parameter Reject time
After 20 metal events, the collector bin is full.
1 s (Reject time) x 20 (Number of metal events) = 20 s (Cumulative ejection time)
To ensure that your machine runs smoothly, you have to set Cumulative ejection time to 20 seconds. After
20 metal events, a notification is displayed, telling you that the collector bin is full. By confirming the
notification, the Cumulative ejection time is automatically reset. Cumulative ejection time can be set to
values between 0 (OFF) and 180 seconds.

Metal counter
4 Line Display: With “Up”, you can set delete metal counter to “ON”. Confirming the dialog
box with “OK” re-sets the metal counter back to zero.
Touch Screen Display: Select “Delete” to set the metal counter back to zero.
see chapter Adjustment Operating level 1 Metal counter

Parameter set
The name, sensitivity, ejection time, ejection delay, learning angle and frequency for a particular product
are linked together to form a parameter set. Changing the parameter set therefore also results in a change of
the sensitivity, ejection time, ejection delay, learning angle and frequency.

Change parameter (Change products)

You can select parameter sets on the left.

Change name

You can change individual parts of the name. You can choose from all characters (small and capital letters)
and all numbers.

Delete

Deletes the parameter set selected on the left.

-56-
Copy parameters

In the menu copy parameters you can copy the values linked to one parameter set to another parameter set.

Create new

Adds a new parameter set on the basis of the currently selected parameter set

Conveyor speed
By means of exact matching to the maximum conveyor speed, external high-frequency influences on the
measurement signal can be eliminated. The set value is dependent on the actual conveyor speed of the unit.
Set the maximum conveyor speed of your conveyor system as the set value.
By adjusting the minimum conveyor speed, low frequency influences on the measurement signal can be
cancelled out. The set value should only be changed if the actual conveyor speed is lower than the preset
value.
Please note:
If the maximum conveyor speed is set lower than the actual speed, sensitivity losses will occur. If you do not
know the exact speed of your conveyor system, it is preferable to set the maximum conveyor speed higher
than the actual speed. In no case should it be set lower.
If the minimum conveyor speed is set higher than the actual speed, sensitivity losses will occur. If you do not
know the exact speed of your conveyor system, it is preferable to set the minimum conveyor speed lower
than the actual speed. In no case should it be set higher.

Measure noise
While measuring the noise faults that concern the seeker coil are measured. Measuring the noise will take
ca. 5 seconds and is measured in [mV].
The background noise comes to 50 mV.

-57-
Frequency

Secondary frequency

If the metal detector is exposed to strong interference in the OFF = Main frequency
factory-pre-set main frequency, and normal operation is ON = Secondary frequency
impossible, you can change to a secondary frequency.

Multi-mode machine:
If you use the secondary frequency setting in combination with a Multi-mode machine, you have to check
that jumpers JP1 and JP2 of the transmitter and receiver boards of the coil are configured properly:

a) Transmitter board type 1 1. Main frequency JP1 = Jumper 1

b) Transmitter board type 2 2. Secondary frequency JP2 = Jumper 2
c) Receiver board

Please note:
• The transmitter and receiver boards are in the transmitter and receiver connector housings of the
seeker coil.
• The transmitter board can be either type 1 or type 2.
• If you activate the secondary frequency, it is automatically activated for both main frequencies.
Changes may only be made by trained and authorised staff.

-58-
Select transmitter frequency (optional)

The menu item select transmitter frequency is only available for Multi-mode machines.
You can choose between two factory-pre-et frequencies, high and low.
Attention:
If the product exhibits a high product effect, or when conveying packaging containing aluminium, you
should select a low frequency as a general rule. Analogous to this, you should select a high frequency if the
product effect is low.
Please note, that the transmitter frequency is connected to the product (parameters).
Difference between selecting transmitter frequency – secondary frequency:
Using the optional transmitter frequency selector for multi mode machines, you can, depending on product
characteristics, choose between the factory pre-set frequencies high and low (e.g. 62.5 kHz and 500 kHz).
The secondary frequency selector only allows the machine to switch to a secondary frequency (e.g. 63.5 kHz
for 62.5 kHz main frequency). If you operate more than one metal detector in the same production
environment, you should indicate this when ordering. The different main and secondary frequencies of the
metal detectors can then be adjusted optimally to each other in the factory. Please note the indications for
setting the secondary frequency with multi mode machines.
see chapter Adjustment Operating level 2 Frequency Secondary frequency

Clock setup
You can set the date and clock. After confirming the seconds setting the clock starts running.
Touch Screen: By selecting the appropriate fields, you can set the values for day, month, year, hour and

Detector test
There are several options regarding when the detector test is to take place. It is possible to carry out the
detector test after each system start-up and / or after the expiration of a defined time interval during
production.

Process of the detector test:

The process of the detector test after switching on is identical to the detector test during production.
The warning „Please start detector test“ must be confirmed with „OK“ to start the test duration. Feed one
reference standard through the detector during the test period. (You can order standardised reference norms
from the manufacturer.) If a metal signal is triggered, the detector is operating correctly.
If no metal signal is detected during this testing phase, or if the metal signal is outside the signal or angle
tolerance range, the error message “Detector test failed” is displayed. Start the detector test manually to
carry out additional tests.
see chapter Adjustment Operating level 1 Start detector test
Please contact our service department if your metal detector does not detect the metal several times in a row.
see Errors and Problems Service

Errors and Problems
7

General
The analysis electronics monitors all components necessary for proper functioning. If one measured
parameter is outside the valid range, the malfunction is displayed as text.
Once an error message appears, the potential-free contact Relay 2 (standard configuration, hereinafter
referred to as standby relay) switches at the same time.
see chapter Technology Plug configuration
The machine is now in error mode.
Certain error messages do not disappear automatically once the source of the error has been remedied.
Error messages can either be acknowledged or cancelled. In both cases, the error message disappears, to
change the settings of the electronics, if necessary:

If the error message is acknowledged, the machine goes back into normal mode (standby relay switches to
normal mode). If the cause for the error is still present, the machine switches back into the error mode after a
short period, and the error message is repeated.
If an error message is cancelled, the machine remains in error mode (standby relay remains in error mode).
After a short time period, the error message is repeated.
Please note: The machine switches back to normal mode only once the error has been remedied and the
message acknowledged.
Notifications behave analogous to error messages, with the only difference, that the machine does not switch
to error mode when they appear (standby relay remains in normal mode).

Calibrating the Touch Screen Display
It is possible that the Touch Screen Display does not react as usual. If a button is ignored when pressed or if
a neighbouring button is activated, the display must be recalibrated.
The calibration fulfils two purposes:
• It determines the active area of the Touch Screen
• It adapts the active area of the Touch Screen to the on-screen display.
While turning-on, press and continue to press the upper left area of the Touch Screen Display until the
message „Display Calibration“ appears. After that, several calibration points are displayed at various
locations on the screen. You need to push these as exactly as possible using your finger or a fine but not
sharp or pointed object. The calibration is subsequently terminated and you jump into the main menu.

Contrast adjustment (Touch Screen Display only)

The Touch Screen display is factory preset. Normally, the display contrast does not need to be readjusted.
However, it could occur after switch-on that the display is too bright and the contrast is increased only with
increased heating in the electronics housing. Those applications in which the metal detector stands in a very
cold environment are particularly critical. During this, the display might appear almost illegible after switch-
on. In this case, you can use a suitable slot-head screwdriver to change the contrast on the rear of the Touch
Screen display.
You can find the exact position of the contrast adjustment screw.

Card reader (optional)

If you run your metal detector with the optional card reader, you will have to reset metal signals by means of
the card reader’s reset button. Manual reset is possible only if there is, at the same time, a Key Card in the
frequency area of the card reader. The data (number of the Key Card, time, date) of every manual reset will
be collected by the electronics and a maximum of 20 data records will be stored. If the maximum number of
entries is reached, the eldest entry will be replaced by the current one. The stored entries may be retrieved or
printed
see chapter Adjustment Operating level 2 Card reader
The configuration of the Key cards is also done in Adjustment Operating level 2 Card reader.
Please note that his option is possible only for “Reset manual”
