If the check box is activated, bit 25 is output as error bit and bit 26
as parity bit. In this case the SSI bit width for transferring the posi-
tion data is limited to 24 bit. The Parity & Error Bit influences the
cycle time of the synchronous measurement. You cannot choose
Parity & Error Bit and Measure Temperature (Bit 24-31) at the
same time.
22
If the checkbox is activated the temperature measured in the sensor
electronics housing will be output (bit 25-32). In this case the SSI
bit width for transferring the position data is limited to 24 bit.
You cannot choose Parity & Error Bit and Measure Temperature
(Bit 24-31) at the same time.
23
Activate the check box to exclude reflections of the position mea-
surement. Thus the cycle time extends. This applies only to sensors
without “internal linearization”. For sensors with option “internal
linearization” the check box “Internal linearization” displays. Via the
check box you can activate or deactivate the “internal linearization”.
24
To select the “synchronous mode 2” activate SSI clock synchron
in SSI settings first. After that activate the check box
Extrapolation/SyncStart.
The “synchronous mode 2” is most suitable for applications where
the polling cycle of the controller can be faster than the measure-
ment cycle time of the Temposonics
®
SSI sensor. The values for the
PLC will be oversampled up to 10 kHz. The delay is similar to the
asynchronous mode.
25
In the field measurement start point and measurement end point
you can define a new working area. Move the magnet to the
desired position and click Set to define a new measurement start
or end point. Via the button Delete you can delete the measure-
ment start and end point again. The current position of the magnet
is displayed within the working area, a magnet outside of the work-
ing area will be ignored.

Use the field Filter to choose a noise reduction filter of two, four
or eight measurements. The RT4 is supplied with a noise reduction
filter. You can adjust the filter via the MTS SSI-Configurator and
adapt it to your application.
16
In the field Measuring you can choose between the following
options:
Position: Measurement and output of position value
Differential: Measurement of two positions and output of the
distance between them.
Velocity: Measurement and output of velocity of the position
magnet, which moves over the sensor rod or the sensor profile.
17
Via Direction you can determine the measuring direction.
Forward: Ascending position values from sensor electronics housing
to rod end
Reverse: Ascending position values from rod end to sensor
electronics housing
18
In the field Resolution (in μm) you can set the resolution of the
sensor. See technical data starting on page 47 for resolution
steps.
19
Offset (in μm) shows the offset which was determined during
the sensor end control at the factory. You can change the offset
(null position) in entering a new value in the field Offset (in μm).
After that you have to press the button EEPROM Update to confirm.
Another possibility is described in
20
.
20
If you like to change the offset, move the magnet into the desired
position. Confirm the position via the button Set.
The factory settings can be restored at any time under the menue
item File.
If the measuring direction changes, the offset will be
converted automatically. If the null position moves into the measuring
range, values < 0 of the binary data fomat will be output as negative.
