Safety instructions
[6]
DANGER!
If device tests have to be completed during operation or if the device has to be replaced or
decommissioned, it will impair the machine protection and may cause the machine to shut

2.3 Radio interference
The device is carefully shielded and tested to be technically immune to radio interference
and complies with current standards. However, if you operate this device together with
other peripheral devices that are not properly shielded against radio interference,
disturbances and radio interferences may occur.
2.4 ESD safety
DANGER!
Internal components can be damaged or destroyed due to electrostatic discharge (ESD) during
handling of the device.
Take suitable precautions before handling the device to prevent electrostatic discharges
through the sensor electronics. Such measures might include, for example, wearing an ESD
bracelet. Transport and storage of electronic components may only be made in ESD-safe
packaging.
Handle the device with particular care during dry meteorological conditions with relative
humidity below 30% as electrostatic discharges can appear more frequently.

Application and design
[7]
3Application and design
Topics covered in this chapter:
•Application
•Design
3.1 Application
The EZ 1000 is a signal converter for different types of eddy current sensors. The converter
is designed for the connection of eddy current sensors of the EZ 10xx series and a selection
from third party sensors:
•EZ 105x and EZ 108x
•Bently Nevada 3300 XL 8 mm Proximity Probes 33010x
The sensor adapter EZ1900-003-ADAP-2 is required for the connection of 33010x
probes.
The EZ 1000, in combination with eddy current sensors listed above, can be used for static
and dynamic distance measurements at a variety of different rotating machinery. This
means that slow axial displacements and fast radial vibrations of rotating machines can be
measured. By using pulse wheels or key marks stuck on the shaft, the speed of the
machine can be measured and key pulses generated.
The EZ 1000 is integrated into Machine Studio which allows an easy on-site calibration of
the converter to the sensor. Machine Studio also provides the opportunity of detuning the
converter if sensors are fitted closely together or to extend the standard measuring range
of several sensors.
Supply circuits for the eddy current sensor and the measuring electronic are contained in
the converter. The nominal supply voltage for the converter is -24 V DC, the nominal range
of the output signal, proportional to the nominal measuring range of the sensor, is
-2 to -18 V.
3.2 Design
The EZ 1000 is designed for DIN rail mounting within a field housing or cabinet. The
connection of converter supply and sensor signal is made by screw terminals. The
converter is equipped with a LEMO connector for connection of an eddy current sensor.
The USB 2.0 Micro-B socket is the interface for the configuration. Figure 3-1 explains the
connections and operating elements.

Function principle
[11]
4Function principle
The measuring coil of the eddy current sensor (for example EZ 1050 or EZ 1080) is
connected to an oscillator circuit in the converter through a shielded connection cable.
The oscillator circuit generates a high-frequency signal resulting in a high-frequency
magnetic field around the tip of the eddy current probe. If this magnetic field meets a
metallic target, it induces high-frequency currents and another magnetic field which is
inversely induced to the original one. According to the rule of Lenz, the induced current
damps the oscillator signal.
The damping factor depends on the distance between sensor head and target material.
The smaller the distance to the sensor, the smaller the amplitude of the oscillator.
The demodulator at the output of the oscillator generates a distance proportional signal
from the amplitude modulated HF-signal. The following units serve the purpose of
linearization and amplification of the signal. The output connectors OUT and GND provide
a signal proportional to the actual distance between sensor head and target material
(measurement object).

A. Metallic target (for example: machine shaft)
B. Sensor
C. EZ 1000
D. Oscillator
E. Micro controller for signal processing
F. Power supply
G. Signal output
H. USB interface
The target material, the sensor, and the sensor cable length have an influence on the
oscillator circuit and consequently on the output signal. The EZ 1000 converter must be
calibrated on the connected sensor, the sensor cable length, and the material of the target
to reduce this influence. Sensor, sensor cable, and calibrated EZ 1000 converter form the
measuring chain.

Function principle
[12]
Note
If installing a calibrated measuring chain at a different measuring point, ensure that the target
material of this point is the same as of the previous point. Otherwise, recalibrate the converter on the
new target material.
4.1 Sensor supervision
The EZ 1000 checks the connected sensor by supervising the signal voltage. A sensor not
OK indication is displayed when the sensor OK limit of -1.5 V has been violated.

Sensor not OK indication:
•
Green LED on the converter front is switched off (see Table 3-1 ).
The green LED is used for sensor, voltage, and converter fault indication.
•
Sensor state in the online view of Machine Studio indicates a fault (see Section 9.1 ).
Table 4-1 lists causes for a sensor not OK indication.
Table 4-1: Causes for sensor not OK indication
Cause Possible reasons Solution
Sensor is too close to the
measuring object.
Machine behavior has been changed. Check the distance and
readjust the sensor
position if necessary.
Loosened sensor holder.

Function principle
[13]
Table 4-1: Causes for sensor not OK indication (continued)
Cause Possible reasons Solution
Sensor cable break Open connector. Check the sensor cable
and connections. Replace
a defective sensor. Check
cable path to avoid further
damages.
Damaged sensor cable.
Sensor head damage Permissible environmental temperature
has been considerably exceeded.
Replace the defective
sensor. Check sensor
adjustment and
environmental condition
to avoid further damages.
Sensor head has touched the measuring
object.
The sensor not OK indication is reset as soon as the voltage is below the limit again.

Hints for installation and connection
• Adjustment of measuring chains at the machine
•
Mutual influences of two measuring chains
5.1 CSA - General safety
Equipment to be installed within another enclosure which provides the safety aspects and
protects the operator from hazards and is suitable for outdoor environment conditions.
5.2 Mounting
Mount the EZ 1000 converter into a suitable housing that contains a mounting rail of type
NS 35/7.5. The minimum space on the DIN rail is equal to the converter width of 26 mm.
The minimum mounting space for the EZ 1000 within a housing is shown in Figure 5-1 .
Note
Ensure that there is no heated surface beneath the EZ 1000.
