MANUFACTURERS DECLARATION
The EMC-law of November 9th 1992 concerning the electromagnetic compatibility with reference to
the EMC-directive EMCD 89/336/EWG is a national law. This directive distinguishes between two
criteria: product components and product distribution.
According to these criteria our products are classified as follows:
-Product components: parts from suppliers which are inoperative on their own.
-Product distribution: not commonly available, sold to qualified persons.
The law states, that an EG-declaration of conformity as well as a CE-marking is not requested for
such components.
In order to meet the requirements of the EMC-directive we supply the following:
- Product related documents which describe the interference radiation of our products. This
information will enable the user to provide all necessary steps to meet the EMC-
requirements during planning and installation.
- EMC-specific components such as filters, chokes, shielded wiring, metal enclosures and others
are available from TAE. TAE will furthermore provide specific technical information concerning the
proper use of such components for their products in order to meet the requirements of the
harmonised standards.
It is the users responsibility to carry out our instrutions and to induce adequate provisions. The user is
also responsible that his machine and installation meets the requirements of the EMC-standards.
Based on the EMC-law and its corresponding standards we have carried out extensive
measurements at our premises. These tests have included our complete product line. With the use of
filters and proper wiring all our products meet the requirements of standard EN 50081-2 (sweep
radiation) and standard EN 55011 class A for industrial use.
The extent of the necessary modification depends on the individual product line. Our pamphlet "TAE
PRODUCTS AND EMC" provides information of the minimum requirements for our products in order
to meet the standard EN 50081-2. Our "GUIDE LINES FOR EMC-CONFORMAL INSTALLATION"
provide information for a properly and EMC-conformal installation.
These guidelines and recommendation for the use of electronic equipment are based on the following
standards:
DIN EN-50178 (VDE 0160:1994-11) Electronic equipment for use in electrical power installations
DIN VDE 0100 Erection of power installations
DIN VDE 0110 Dimensioni ng of cl earance and c reepage distances
DIN 40050 IP-Protections
DIN 50081/50082 EMC Basic Standards

3.0 Test Mode
Figure 1: Front view of the Frequency Meter FM 2000
In order to start the test mode of the FM 2000 key T1 must be pressed and be held while
key T2 is pressed at the s am e t im e. Not e: The test mode cannot be started during the
configuration function.
During the test mode all display functions are individually tested and each single digital
display will show one after the other the numbers 0 to 9 and the decimal point.
4.0 Algorithmical Adjustments
The Frequency Meter FM 2000 is being configurated with two keys T1 and T2 and with the
parameter counter P.
The algorithmical adjustment is act ivated by pressing key T2. T he parameter count er P will
now indicate the number 1 and the decimal point of the parameter count er will also light up.
This indicates that the paramet er counter can be increased by a repeated pressing of k ey
T2. The other f ive digital display units will show the value which has been recalled by the
parameter counter P.

In order to change the indicated paramet er the decimal point must be moved to the
individual display unit by pressing key T1. The indicated number of this display can now be
altered by pressing key T2.
If key T1 is pressed again the system retur ns t o the parameter counter P.
Pressing now key T2 again will increase the parameter counter to the next parameter. At
the end of the algorithmical adjustment the parameter counter will return to t he opterating
mode and the new values of the parameters are stored. The FM 2000 will now operate with
the set new parameters.
NOTE: This newly set parameter cannot be cancelled if t he line voltage is int er r upt ed!
All parameters can be changed as often as r equested and any parameter which is not to
be changed can be scipped with the parameter counter by selecting t he next par am et er .
5.0 Multiplier Adjustment
When the param et er c ount er P shows the number 1 it is possible to set a multiplier for the
actual measuring value. The standard value is 01000.
This standard value corresponds to the multiplier 1.0. I f for instance the fac t or 0.5 is
requested the parameter mus t then be adjusted to 00500.

The requested segments ( 1 t o 5) c an be activated with key T1. The decimal point of the
activated segment lights up. The figures can now be selected with key T2. Activating key
T1 will return the system to the parameter counter P after the parameter 1 has been
completely adjusted.

b) Activate with key T1 the first digit display
c) Select with key T2 one of the above mentioned modes
d) After complete set t ing of parameter 2 return t he parameter counter by pressing
key T1 again.
6.2 MODE Selection
The FM 2000 offers the selection between seven diff er ent MODES in order to adapt the
display of the measured values to the individual requirements. The selected MODE applies
to the display only and is independent from the selected multiplier. The following MODE
selection is indicated in the parameter 2 on the second digit segment (second from rig ht )
and refers to the operating m odes: frequency meter and period-t im e m et er :
MODE 0: Standard display ( no changes)
This mode provides the display of the measured value without any change.
example:
operating mode 0
Frequency meter
operating mode 1
Period time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates
567
6735
MODE 1: last digit shows 0
This mode is used if the measuring pr ocedur e with 10 times m easuring accuracy is too
slow and the flickering of the last digit should be eliminated.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates

The FM 2000 offers a new measuring method which allows to measure with a 10-times
accuracy without a substandial increase of the measuring t ime. However the last two digits
will need about 10 seconds before the correct value is indicated.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates
5678
67358
MODE 3: Shifting of the display with additional 0
For lower frequencies it may become necessary to abtain a larg er indicat ion on t he display
without the delay of 10 seconds for the measuring t im e. In this case the display is shifted
one digit to the left and a zero is added at the end.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates
5670
67350
MODE 4: Steady Display
Due to different measuring methods most instruments show a flickering of the last digit in
their display.The measuring method of m ode 4 is t he s am e as it is used for mode 2 but with
the intention to eliminate the flicker ing of the last digit.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz

6.3 Decimal Point
The decimal point can be placed on four different positions of the display. Number 3 of the
parameter 2 shows the position of the decimal point:
Example:

The requested segment c an be act ivated with key T1. The decimal point of the activated
segment lights up. The place of the decimal point can now be selected with key T2.
Activating key T1 will return the system to the param eter counter P after the par am et er 2
has been completely adjusted.
7.0 Measurement Display
In the operating conditon it is possible to measure the input frequency to the FM 2000
without reference to the preset mult iplier by keeping the key T1 pressed.
8.0 Example
This example refers to the connection of the FM 2000 to the DC-Brushless-Control Series
''TA-BL...'' from TAE and can serve as a sample for any other application. The speed (rpm )
of the brushless motor is to be indicated on t he FM 2000 by using the frequency output.
Assumption: The output frequency of t he c ont r ol is t wice as high as the motor speed.
Adjustment: The above mentioned assumption requires a multiplication fact or at 0,5.
As previously indicated under point 3 the parameter 1 must be set to 00500. The parameter
2 should be adjusted for 000, that m eans the operating mode, the mode selection and the
place of the decimal point are set to 0.
The result from these adj us t m ents is that for instance for an output frequency of
3456Hz the display will indicate 1728 which corresponds to the actual motor speed.
