icon.
In case of threshold violation the values are shown in red color. This can be resetted with the “reset
thresholds” button.
The Accelerometer values are shown as mean (average of ~170 values) and variance (how much it
differs from the average)

5.7.1 Chart View Options
a. Refresh: If the user zooms in on the chart, tap on this icon to restore the original view.
b. Enable/disable scrolling in the visible window to show all X values in the graph.
c. Enable/disable auto scale of the y axis of the graph.
d. Start / stop: Tap on this button to show / freeze streaming data in the graph.
e. Starts / stops recording the streaming graph.
f. Share the CSV of the last recorded session.
Note
Please attention! The data that you are recording in Diagram view is not the raw-data coming from
the sensors. It is the data shown in the graphics. For example Accelerometer values are aggregated to
mean and variance values. If you need the data for data analysis, please use Logging page to log and
download raw-data. The raw-data is more suitable to detect all details in data analysis.

Note
The downloading process may take several minutes. Logging must be stopped in order to proceed
with the download.
Note
Please note that SCD can log only one axis (z-axis) in 6.4 kHz sampling rate. Logging 3-axis in this
speed is not possible. With all the other sampling rate options 3-axis data is saved.
Note
Please use the raw-data from the logging function in the data analysis. This data is recorded directly in
the embedded device (SCD), and transferred later. In this way, it is possible to save the data in high
sampling rates. Please don’t use the recorded data in Diagram view which is aggregated to reduce the
data volume in streaming.
5.9 Removing the SCD
5.10 Reusing the SCD
After the SCD has been removed, it can be reused. For mounting, proceed as described in 5.1 Mounting the
SCD. Please note that after removal the IP67 certification is no longer guaranteed.
INFO: IP67 certification can no longer be guaranteed after removal.
INFO: Do not use any sharp objects to remove the SCD.
TIP: The machine temperature should be below 40 °C.
Run a flat tool without a
sharp edge between the
SCD and the surface.
Carefully lift the SCD and
release it from the machine
surface.

6General Operating Modes of SCD
The operation modes are described in this chapter. For information about how to configure the SCD or how to
retrieve data from it, please refer to chapter 5 Installation and Start to Use.
6.1 General Behavior
The user can activate/deactivate each sensor in SCD to get data. Additionally, for logging the data, user can
specify different sampling rates for each sensor. On the other hand, SCD uses an optimal (fixed) sampling rate
to stream the data to the app to be visualized.
6.2 Resetting the SCD
If there are problems with the SCD, a restart of the SCD may be necessary.
In order to reset the SCD, please do the following steps:
Press the button on the SCD for at least 10 seconds.
When the button released after 10 seconds, the LED shows a short red light.
6.3 Streaming via Bluetooth Low Energy (BLE)
SCD is a Bluetooth Low Energy (BLE) device. This means that another BLE device may detect the SCD when
scanning for devices and is able to initiate a connection. By using BLE, it is possible to configure the SCD and
continuously receive measurement data. The data can be visualized in the app or consumed in a gateway. If the
user wants to integrate the SCD into his/her gateway, the required document e.g. the SCD BLE Communication
Protocol is publicly available in the website to download.
6.4 Logging Data into the Local Memory
SCD can be configured to log raw-data into its local memory. This data can be downloaded afterwards by the
smartphone app or by a gateway. Logging into the local memory is the right way to get accurate raw-data for
data analysis. SCD is able to log data in the memory, and at the same time, stream the data via BLE.
When the user starts logging in the app, the SCD continues to log data until the local memory is full or logging is
stopped by the user. The time until the memory is full depends on the SCD settings. Please see below some
examples.
Examples:
Accelerometer @6.4kHz (1 axis) will fill the memory in 60 seconds
Accelerometer @3.2kHz (3 axis) will fill the memory in 40 seconds
Accelerometer @1.6 kHz (3 axis) will fill the memory in 80 seconds
Temperature alone will fill the memory in 21 days
INFO: All stored values are lost in this process. Only the name of the SCD stays unchanged.
