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 Machine factor
The Machine factor determines the relationship between the measured sensor frequency and the
corresponding speed.
There are two means of determining this value:
4.2.1 Measured
Where the Frequency (f) at the Sensor input and the corresponding speed (n) is known:
4.2.2 Calculated
The relationship between Sensor Signal Frequency (f) and speed (n) at a Pole wheel is:
Machine factor is then:
Should a gearbox be present between the pole wheel and drive shaft the formula becomes:
The gearbox ratio is determined as follows:
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.
