2 Safety Warning
During operation, parts of the FT 3000 are under dangerous voltages. The units conform to protection class 1 and
require an earth connection on the corresponding module connector and/or terminal on the 19" rack.
The units have been designed and tested in accordance with IEC 348 and have left the factory in perfect condition.
These operating instructions include information and guidance on the safe operation of the equipment and installation.
Please specially note section 6.
If in doubt about the condition of any part following electrical, environmental or mechanical damage, the unit should be
returned for repair.
3 Applications
FT 3000 tachometers are used to monitor and measure frequencies in the range 0 to 30000Hz eg from frequency
proportional sources such as rotational speed.
The FT 3000 family comprises of the following modules:

•Mains filter (2 wire) FTZ 3069 Art. Nr. 804D-35886
FT 3000 3 channel speed monitoring and over speed protection systems comprise of 3 independent channels, from
speed pick ups through to limit signalling. High integrity operation is provided for in the rack through the use of 2
redundant power supplies to each module via diode decoupling. Rack module supply requirements are matched to the
incoming supply by the 2 redundant power supplies.
4 Construction
The modules are plug in units in a 19" rack, with height 3 HE and with 4, 12 or 20 TE in accordance with DIN 41494.
Compatible card frames with up to 21 locations at 4 TE are used for mounting and wiring the modules. The card frames
are built by JAQUET to customer requirements. Connections for speed sensors, control and output signals along with
power supplies are normally provided at the back via screw terminals or Termi-Point connections.The setting of
measuring range, monitoring and relay parameters is via front panel RS 232 interface on the FTK 3072 comms module
to a PC. This module controls the data flow between the PC and individual modules in the rack (RS 485 rack bus). The
parameters are stored in EEPROM’s and protected against mains failure.

PFHg according to IEC 61508-2 : 2.69e-8 fits
DC % according to IEC 61508-2 : 94.23%
Life duration for the system is 20 years. During this period the data integrity of the programable devices are garanted,
this time is equivalent to the MTBF of the channel. After this period the overspeed protection system must be replaced.
6.2 IEC 61508-2-3 specifications :
•System configuration for the Overspeed Protection System :
The system definition must include for reaching the IEC 61508-2-3 and SIL 3 conformity an alarm signal with
following activated selfcontrols for the S + M + P Alarm output :
-System check : Watchdog, Parameter monitoring, software test
-Sensor monitoring : Static and/or dynamic sensor monitoring activated
-Power supply check : monitoring of the supply voltage
In addition, for a safe system behaviour in the case of multiple faults, the system S +M + P Alarm must be
combined with the overspeed signal. This means that multiple detected system faults generate a trip.
Only 3 channel systems can fulfil the IEC 61508-2-3 requirements.
•System configuration for the optinal additional Trip Chain Control Card.
Only a 3 channel Trip Chain Control System can fulfil the IEC 61508-2-3 requirements for SIL3. The voted or
non voted TCCC signals can be combined with OSPS trip signals.
•System installation :
The installation specification must be kept for reaching the IEC 61508-2-3 conformity. These specifications must
be realised by the system integrator / end user. See chapter Installation.
•System maintenance :
The maintenance specification must be kept for reaching the IEC 61508-2-3 conformity. These specifications must
be realised by the system integrator / the end user. See chapter Maintenance.
6.3 Technical data OSPS
Reference conditions: Operating temperature +20ºC
Supply within defined limits
Smallest measuring range: 0...1.000 Hz
Largest measuring range: 0...35.00 KHz
Once the machine factor M is defined (M = Freq. In Hz/ measured value eg rpm), the input of measuring range and
limit values is directly in the chosen physical units eg rpm. In place of the machine factor, the number of pulses per rev
from the pole wheel may be entered. Moreover once the nominalspeed is defined (=100%), limits can be given as a
percentage of nominal. The measured range may be continuously exceeded up to 55KHz without affecting
functionality or causing any damage to the unit.

7 Principle of operation
7.1 Measuring system
The measuring system on the FTU 3024 motherboard processes four frequencies, F1, F2, F3, F4.
Input F1 is derived from the amplified sensor signal from the input card EOX. Inputs F2 and F3 are derived from
the outputs of additional FTFU 3024’s present in a 3 channel system. Input F4 is derived from the test frequency
generator.
7.2 Measuring principle
7.2.1 Standardising the measured value
Following input of the machine factor M = f/n, where f = sensor frequency in Hz for a known speed and
n = machine speed in rpm
or input of the number of pulses per rev (nr. of pole wheel teeth), the frequency relay limit values and the converter
measuring ranges can be directly entered in rpm.
The relationship between the sensor signal frequency f and the speed n of a pole wheel to be sensed is
f = n * p/60 where f = sensor frequency in Hz
n = pole wheel speed in rpm
p = nr. of pole wheel teeth
For rotational speed measurements the machine factor M = p/60.
In place of speed n in the formulae above, any other frequency proportional physical unit may be used.
If the limit values and measuring ranges are to be entered in percent of nominal, the above calculations are still
required.
7.2.2 Speed monitor
The max 3 speed monitors are based on hardware re-triggerable One Shot circuits that are set with every positive edge
of the input frequency. The timebases are derived from 3 down counters that are set with the set point frequency and
clocked down using a 2.5MHz reference signal. If the counter reaches zero before the arrival of the next positive edge,
this indicates that the input frequency is lower than the set point. These functions for one limit value are performed in an
ASIC (Application Specific IC). The preset values for the down counter are computed by a microprocessor for the
required set point and loaded into the ASIC.
The 3 speed monitors continuously collect speed frequency data without interruption.
Each speed monitor is supplied with 1 of 5 possible input signals, defined by software configuration (None, F1, F2,
F3, F4)
7.2.3 Frequency measurement (Period measurement principle)
FT 3000 tachometers work on the continuous period measurement principle. The measuring chains for 3 frequency
measurements are implemented in hardware using ASIC’s. Each of the 3 ASIC’s contain a counter to measure the
period duration of up to 3 frequencies. The mpu reads the counter’s status with each positive edge of the input
frequency. The difference between the status of 2 counters is a measure of the period of the input signal. The frequency

Operating Instructions FT 3000JAQUET AG
377E-63917 Rev 4.00 page 18 of 47
data is continuously collected from all 3 measuring chains without pause. The number of periods measured is
determined by the Fixed Time and the magnitude of the input frequency.
The measured value (rotational speed) is then computed by the mpu. There are then 3 floating point values
available - <AbsolutA>, <AbsolutB> and <AbsolutC>.
Each measuring chain is supplied with 1 of 5 possible input signals, defined by software configuration (None, F1, F2,
F3, F4).
7.2.3.1 Measurement functions
Based on the measured values <AbsolutA>, <AbsolutB> and <AbsolutC>, the following functions can be realised:
<FunctionOutput>
•Majority value of A, B and C: From the 3 values 2 are selected that display the smallest difference
and used to generate an average value.
•Max value of A, B and C: The max value is selected from the 3
•Min value of A, B and C: The min value is selected from the 3
•Average of A+B+C
•Average of A+B
•Average of B+C
•Average of C+A
•Difference A-B
•Difference B-C
•Difference C-A
•Ratio A/B
•Acceleration 1 (Accel. 1) :
Accel1 = (speed2– speed1) / (time2– time1) (RPM/s)
•Acceleration 2 (Accel. 2) :
Accel2= Accel1/ speed1 (RPM/s)
Accel2 units could also be %/s, this means that we are speaking here of a rate of change from the nominal
speed.
The function is defined by software configuration.
7.2.3.2 Max value memory
The max value memory <MaxMem> registers the maximum value of a measurement (Drag pointer function)
The max value memory can only be reset via an intentional entry ResetMaxMem in the CommandByte or through total
power failure. Which measured value is stored is defined by the software configuration -
•<AbsolutA>
•<AbsolutB>
•<AbsolutC>
•<FunctionOutput>
Always remember to reset the Max value memory following testing with internal generators.
Speed measurement and over speed trip monitors are separate functions within the FT 3000.
In operation, there are 2 main reasons why the recorded Max value may not correspond to the
limit setting:
- the trip point is reached but the machine runs on until the shutdown valve has closed. The maximum
speed the machine reached prior to shutdown is therefore recorded.

Operating Instructions FT 3000JAQUET AG
377E-63917 Rev 4.00 page 19 of 47
- gear machining inaccuracies, coupled with a low number of pulses configured for the trip
setting may result in the over speed monitor activating the trip relay at a speed apparently lower
than the limit set. The solution to this is to increase the number of pulses used to say 20% of the number
of teeth on the gear
7.2.3.3 Comparators
Each of the 4 comparators can be allocated one value from the following list by software configuration -
•<AbsolutA>
•<AbsolutB>
•<AbsolutC>
•<FunctionOutput>
•<MaxMem>
A comparator compares the actual measured value with the predefined set point and establishes limit status
(upper/lower limit reached)
7.2.3.4 Analog outputs
Each of the 3 analog outputs from the FTW 3013 can be allocated one measured value via software. The start and end
values for each range can be independently defined. Rising and falling characteristics are permissible. Each analog
output may include a low pass filter with software configurable time constant.
7.2.4 Acceleration measurement
The acceleration is measured with the speed measurement unit implemented in hardware (FPGA). The measurement of
the speed is made every 10 ms (for speeds greater than 100 RPM). The precision of this measurement is determined by
the clock of the „time counter“, which is 2.5 Mhz. Here we consider that this clock has no jitter, what is true due to the
integration of the jitter during the measurement
The relative measurement accuracy of the acceleration is defined by :
)/( )(
*8.0(%) sRPMonaccelerati RPMspeed
onaccelerati onaccelerati =
Δ
For example :
Speed = 3000 RPM
Acceleration = 1200 RPM (rate of change of 40% per second)
The reachable accuracy is +/- 2% for the acceleration.
