1 Safety notice
T501 Series tachometers may only be connected by competent personnel.
T501 tachometers do not generate dangerous potentials but as soon as circuits
exhibiting dangerous potentials are connected, then these may be present in the
tachometer circuits.
The Tachometers may only be opened for repair by trained personnel.
These Instruments correspond to protection class I. The PE terminal must therefore
be earthed.
The instructions in this manual must be strictly adhered to.
Not following these instructions could result in damage to equipment or plant and injury to personnel, as well
as negating warranty claims!
Units that have suffered electrical over load, mechanical stress or been operated outside of specification
must be immediately switched off and returned to the manufacturer for repair.

4 Principle of Operation
4.1 General
The T501 Series of tachometers are microprocessor controlled and operate in accordance with the period
measurement principle whereby the duration of the input period is measured during the measurement interval.
The reciprocal value based on the average input period corresponds to frequency and hence speed.
The relationship between frequency and speed is determined by the Machine Factor.
The status of System Limits is based on various inputs that can be logically combined AND or OR. System
Limit inputs may be: both speed inputs, a Math function based on the speed inputs and, the 2 binary inputs. A
hysteresis may be set for the speed inputs and Math function individually. The 6 System Limits in each of 4
parameter sets may be individually defined. Parameter sets may be selected via binary inputs. The 4 relays
and 2 open collector outputs may be assigned to any System Limit and will react accordingly. The 2 open
collectors may alternatively be assigned to frequency x1, x2 or x4. Relay and open collector status may be
latched and then reset via binary input.
The system permanently monitors itself. Sensors may in addition be monitored. Sensor error may be used in
the configuration to influence System Limits. System error would influence the relays, open collectors and
Analog outputs and the front panel LED would go out.
Frequency Outputs (Open Collector Outputs) are not influenced by the Machine factor but where so defined
correspond to the input signal. For frequency x2 or x4 the 2 input signals should ideally be phase shifted by 90
degrees.
Parameter input is via resident PC software and the Ethernet Interface. This may also be used to interrogate
the unit, display measurement and unit status.
The Parameters are safely stored in EEPROM.

4.2.3 Other physical parameters
In principle any parameter may be processed as long as it can be translated into a frequency proportional
value. The formulae above may still be applied whereby the required parameter is used in place of speed.

5 Installation
Series T501 tachometers may only be installed by competent personnel. Only undamaged and correctly
configured units may be used. Please note the safety instructions in Paragraph 1. They should be connected
to the power supply by means of an isolating switch and correspond to protection class I. The PE terminal
must therefore be earthed.
Before switching on check that the supply is within the permissible range.
The Sensor cable screens must be connected terminals „Sh1“ and „Sh2“ respectively so as to minimize the
effects of signal noise. These terminals are internally connected with 0V (not PE).
Attention: If the password has been changed, there is no way of returning to a factory setup. If the password
is forgotten, you have to send in the tachometer and the Jaquet- Service- Team will set it back.

7 Configuration via PC Software
7.1 Software Concept
The T501 Ethernet connection is used to configure or interrogate the unit. (see Paragraph 10 Accessories)
The resident menu driven configuration software is used for unit set up.
Normal PC file handling procedures apply and the configuration file can be communicated between computer
and T501.
To run the Software you must have Java Runtime Environment (JRE) 1.5 or higher.
7.2 PC Settings
The PC Ethernet card must first be set correctly. T501’s cannot be
used on a network.
Go to Desktop, Settings, Network connections and right click on
<Properties>. Right click the Network card you want to use for T501
comms and select <Properties>.
Select Internet protocol (TCP/IP) and select the Option <IP-Address
automatically recognize>

8 Operating behaviour
8.1 Power on
The parameter set e.g. as defined by binary inputs is immediately valid.
8.1.1 Analog Output
Immediately after power on the output corresponds to the lower range value set. Following the first
measurement interval the output corresponds to the measured value.
8.1.2 Relay Output
Up until the first measurement interval is completed, all relays are de-energised. Thereafter they assume the
defined condition.
If no input frequency is present then after measurement interval x 2, 0Hz is assumed.
8.1.3 Open Collector Output
Up until the first measurement interval is completed, all Open Collectors are inactive. Thereafter they assume
the defined condition.
If the Open Collector is assigned to a frequency, then it immediately assumes the corresponding status.
If no input frequency is present then after measurement interval x 2, 0Hz is assumed.

8.2 Frequency Measurement
Every frequency measurement starts with the negative edge of the input signal. The last measured edge prior
the end of the measurement interval completes the running measurement and immediately starts the next.
An optimum measurement is achieved when the input period is shorter than the measurement interval.
End of the measurement interval
Input signal
Time
Input period
Measurement
If the input period is greater than the measurement interval, the frequency is calculated as follows:

n: Number of measurement intervals without input signal
This continues until a second negative edge arrives.
End of the measurement interval
Input signal
Time
Input period
Measurement
The calculation and adjustment of outputs occurs immediately after the start of the next measurement interval.
If the input frequency is lower than the lower limit (0.025Hz), then the output will be zero. The measurement of
input frequencies above the upper limit (50kHz) is not guaranteed.
8.2.1 The Adaptive Trigger Level
The trigger level is continuously adjusted for
successive pulses. This guarantees that the trigger
level can follow a 50% reduction in speed from pulse
to pulse. DC offset, resonance and negative pulses
have no effect on the triggering

Signal failure is defined as the sudden transition from an input frequency to no further recognisable pulses.
The frequency is then calculated as follows:

f =
n: the number of measurement intervals without an input signal
tMeasuremen t × n
The measured speed thereby follows an exponential function to the minimum frequency (0.025Hz) and then
falls to zero.

8.3.5 Frequency x2 and x4
Prerequisites for the x2 and x4 function are that the input frequencies are synchronised, they exhibit
approximately 90 degrees phase shift and a Mark : Space ratio of approximately 1:1.
The x2 function is an EXOR combination of input frequencies S1 and S2. The x2 output frequency can reach
a max value of 35kHz.
The x4 function is based on doubling of the x2 frequency and generates a 10us output pulse each time a
positive or negative x2 edge is detected.
The Mark : Space ratio thereby changes with frequency. The x4 output frequency can reach a max value of
35kHz.

8.3.6 Relay and Open Collector Latch Function
Relays and Open Collectors can be assigned a latch function. If a signal arrives from the assigned function the
relay / OC is latched and remains latched until reset via binary input or the <Exec> button.
Where fail safe mode is selected the deactivated Relay / Open Collector state is held.
8.3.7
Analog Output
If an analog time constant higher than zero is set, with measurement
interval of 2ms, then the max. frequency that can be measured is
35kHz.
To measure frequencies higher than 35kHz with time constant higher
than zero, a min. measurement interval of 5ms must be selected.

Interpretation of system limit inputs
Upper and lower set points may be set for each of the 3 system limit inputs. In this way a hysteresis is defined.
If the upper set point is exceeded then this input assumes a status of 1. When the lower set point is then
passed, the status returns to 0. If the actual value lies between the 2 set points then the status is as before.
If a parameters set change takes place when the actual value lies between the set points, then the status also
remains as before.
8.4 Fault behaviour
8.4.1 Sensor error
The sensors may be monitored in 3 ways.
•
•
•
Sensor powered by the T501 – Sensor supply current monitoring.
If the current falls outside of the defined range then static error is signalled.
Sensor not powered by the T501 – wire break detection.
Static error is signalled when wire breakage occurs. (Impedance measurement of 2 wire sensor)
2 speed sensors connected – Dynamic sensor monitoring, i.e. the 2 signals may be compared. If the
values differ by more than the defined tolerance, dynamic error is signalled.
The T501 behaviour in the event of a sensor fault is a function of the software configuration. If sensor
monitoring is selected, a fault causes the LED to go off and the analog output (both) go to error status. The
Relay and open collector behaviour is a function of the configuration.
8.4.2 System alarm
The microprocessor continuously monitors the following functions for errors: Supply, math functions of the
micro controller, RAM, EEPROM.
In the event of a fault the relays are de-activated, the current output goes to 2mA (4-20mA) or 21mA
respectively and the Open Collectors become high resistance if assigned to a function other than frequency
output. The T501 then initializes and attempts to run again.
8.5 Power failure
If the power fails for longer than the bridging time the outputs are de-activated, i.e. Analog outputs go to 0mA,
relays de-activate and the Open Collectors go to high resistance.
As soon as the supply returns to the minimum required the T501 recommences its initialization routine.
8.6 Behaviour during Configuration
During the transmission of configuration or process parameters to the tachometer, it goes into a safe mode,
i.e. the outputs assume a defined state. For individual outputs that means:
• Relays:
are no longer powered
• Open Collectors:
become high resistance
• Analog outputs: assume the fault mode according to the configuration

11 Maintenance / Repair
T501 tachometers do not require maintenance since they exhibit minimal drift and do not use batteries or other
consummables.
If the instrument is to be cleaned please note the protection class!
It is preferable to remove all forms of power (including relay contact supply) during cleaning. Surface cleaning
may be carried out using spirit, pure alcohol or soap only.
