4 Product description

4.1 Device description

The frequency voltage/current converter KFU8-FSSP-1.D-Y is a device for displaying and monitoring periodical signals which occur in almost all areas of process automation, i.e. from general frequencies to specific speeds.

The input signals are evaluated and converted into a frequency or speed by a powerful -controller in accordance with the cycle method. The -controller calculates a voltage value proportional to the input frequency and produces it with a digital/analog converter in accordance with the selected limit value of the measurement range.

You can select either of the following analog signals:

• 0 V ... 10 V• 2 V ... 10 V

The pulse output produces the input frequency which is subdivided by the adjustable factor of 1 ... 9999.

Furthermore, in applications involving slow processes, where sensors deliver multiple pulses per revolution, it is possible to automatically operate with the actual speed of the drive by specifying the number of pulses per revolution.

NOTE!

Close attention was paid to the special case of speed measurement during the development of the device. The indicators and inputs can therefore occur in Hz or in rpm.

10

KFU8-FSSP-1.D-YProduct description

046792 2008-11

The input or output signal is displayed on a 7-segment LED display on the front of the device. The display has 4 digits and up to 3 decimal places. The parameterization is performed using the 4 buttons below the display.

The frequency voltage/current converter is supplied with 24 VDC.

NOTE!

All currently available two, three or four-wire proximity switches and incremental rotary encoders are acceptable as sensors.

KFU8-FSSP-1.D-YOperation

KFU8-FSSP-1.D-Y

046792 2008-11

5 Operation

5.1 Operating mode

Signal frequency

The frequency voltage/current converter processes input signals of 0.001 Hz ... 9999 Hz or speeds of 0.02 rpm ... 9999 rpm. Signals not having a duty rate of 1:1 must have a minimum pulse pause or pulse duration of 40 s in order to be detected with certainty behind the input filter.

Measurement underrange, message

This message appears when no input signal is recognized.

Measurement overrange, message

The preset display and measurement range was exceeded.

NOTE!

Select a wider measurement range.

12


046792 2008-11

Very low signal frequencies, displayed value is not valid,

message

During the measurement of very low signal frequencies, the measuring system has detected that the signal has fallen below the last computed frequency. The time between the last two signal edges has already elapsed. The device is now waiting for the next positive signal edge in order to compute the next measured value. Here, 'XXX' represents the positions of the first three digits of the last measured value.

Self test, message

When the power supply is switched on, the device performs a self test. The message appears when it is established that there is an error, for example during the check summation of the EEPROM data; in this state, the output relay behaves as if there has been a power failure. The error message can be cleared by switching the supply voltage off and on again.

Error message

NOTE!

If, when switching on again, the error message appears, then the factory presets were loaded.

13


046792 2008-11

1. Enter the parameters again.

2. Switch the device off and back on again.

The normal function of the output relay is restored.

5.2 Setup mode

view Figure 6.2 on page 29

Transition operating mode setup mode

Starting setup mode

Press the "Mode" and "+" buttons at the same time.

The display shows the parameters in text form.

Transition setup mode operating mode

Exiting setup mode

Press the "Enter" and "+" buttons at the same time.

The parameters are stored in an EEPROM in a non-volatile manner.

NOTE!

You can modify the parameters in the parameter value display (flashing digits). The parameters come into effect temporarily until the operating voltage is interrupted.

Button functions for the parameter display

Button functions for the parameter value display (one digit flashes)

Function selection

(factory preset: Rotational speed measurement in rpm)

2 measurement functions are available:

1. Frequency measurement in Hz (parameter value = 0)

The established cycle duration of the input signal is converted into a frequency

in Hz through the formation of a reciprocal value.

Range: 0.001 Hz ... 9999 Hz

"+" Switch to next parameter.

"-" Switch to previous parameter.

"Mode" Switch modes of parameter display.

"Enter" and "+"

Closes parameter editor and stores all parameters in the EEPROM.

"+" Increase the value of the flashing digit.

"-" Decrease the value of the flashing digit.

"Mode" Move flashing digit.

"Enter" and "+"

Transfer from parameter value display to parameter display.

15


046792 2008-11

2. Rotational speed measurement in rpm (parameter value = 1)

The signal frequency calculated from the cycle duration is multiplied by 60 and

displayed in rpm.

Range: 0.02 rpm ... 9999 rpm

Pulse divider

(factory preset: 1 pulse/revolution)

Applications involving slow processes are frequently equipped with sensors which provide several pulses per revolution. In the rotational speed measuring function, the device undertakes the conversion to the actual value of rpm by inputting the numerical value (of pulses/revolution), i.e. both the indication and the input of the measurement range end value are obtained from the actual rate of rotation of the drive.

Range: 1 ... 1200

NOTE!

The pulse separator is only active for rotational speed measurement.

16


046792 2008-11

Measurement range full scale reading

(factory preset: 9999)

In frequency measurement, the set value is measured in Hz or in speed measurement it is measured rpm (depending on Function selection) it determines the frequency or speed at the analog output of the maximum voltage of 10 V.

Range: see display and measurement range.

Display function

(factory preset: frequency or speed)

The display shows the determined frequency or speed in Hz and rpm (depending on Function selection) or the output voltage in V.

Display rate

(factory preset: 0.33 s)

In order to ensure good readability of the display, the time taken to indicate the current measured value in the display can be selected between 0.01 s and 2.5 s.

Display function Function selection Analog output Display

0 0 - Frequency in Hz

1 - Rotational speed in rpm

1 - 0 Voltage in V

- 1 Voltage in V

NOTE!

The display rate influences neither the time required to calculate the measured value nor the switching characteristics of the output relay.

18


046792 2008-11

Division factor for the pulse output

If the division factors is set to 1, the pulse output goes to high level approx. 25 s after the positive slope of the input signal and to low level approx. 50 s after the negative slope.

Figure 5.1: Division factor 1

With division factors greater than 1, the pulse output goes to high level approx. 50 s after the first positive input signal slope.

For even division factors the output level goes approx. 50 s after the ‘division factor’/2 period to low level for the following periods.

approx. 25 μs approx. 50 μs

19


046792 2008-11


For uneven division factors the output level goes approx. 50 s after the (‘division factor’-1)/2 period to low level for the following periods.


Range: 1 ... 9999


Example:division factor = 4

output level high:4/2 = 2 periods

Example:division factor = 5

output level high:(5-1)/2 = 2 periods
