8.1 Installation considerations
To maintain the accuracy stated in the technical data, the sensor must
be installed inline and fitted to tubes with the same diameter. Please
note the following:
•The sensor is for indoor use only! At an outdoor installation, the
sensor must be protected from solar radiation and rain.
•It is strongly recommend not to install S415 permanently in wet
environment which e ists usually right after a compressor outlet.
8.2 LED indicators
The S415 provides four LED indicators on the display panel, which
indicate the status of the data logger, display, and Bluetooth connection
separately.

8.3 Electrical connection
The flow sensor comes with two connector plugs “A” and “B”. By default
the sensor is delivered with one 5 m cable with a M8 connector on one
side and open wires on the other side. To make the S415 work, one
cable connection is sufficient. However, if the pulse output is to be used
or the supply and the signal need to be on separate cables, a second
connection cable must be ordered.

9 Sensor signal outputs
9.1 Analog output
The sensor has an analog output of 4 ... 20 mA. This output can be
scaled to match a desired measuring range. Standard scaling is from 0
to the ma flow. The corresponding flow in different pipe sizes can be
found in section 13.1.
9.2 Pulse output
The sensor outputs one pulse per a consumption unit. This pulse output
can be connected to an e ternal pulse counter to count the total
consumption. The number of m3 per second are summed up and
indicated after one second. Pulse length depends on flow rate.

In the response message that the device returns to the master:
•Function code: 03
•Byte order (32-bit data): MID-LITTLE-ENDIAN.
To properly decode the 4-byte float and unsigned integer data in
the response message, the master must change the byte order
from MID-LITTLE-ENDIAN to the order that it is using (LITTLE-
ENDIAN or BIG-ENDIAN).

To change any settings on the S415, please download and install the
service App S4C-FS from the Google Play store or our Website. This
App works on any Android system with Bluetooth supported.
To be allowed to change settings, the App needs to scan the QR code
attached on the side of the sensor head or on the calibration certificate.
This ensures that only authorized users can access the sensor settings.
For more information about instructions, see the S4C-FS Instruction and
operation manual.
ATTENTION!
Changes on the settings may lead to wrong
measurement results! Contact manufacturer in case
you are not familiar with the settings.

11 Calibration
11 Calibration
The sensor is calibrated e work. The e act calibration date is printed
on the certificate which is supplied together with the sensor. The
accuracy of the sensor is regulated by the on site conditions,
parameters like oil, high humidity or other impurities can affect the
calibration and furthermore the accuracy. However we recommend to
calibrate the instrument at least once per year. The calibration is
e cluded from the instruments warranty. For this please contact the
manufacturer.
12 Disposal or waste
Electronic devices are recyclable material and do not
belong in the household waste.
The sensor, the accessories and its packing must be
disposed according to your local statutory requirements.
The dispose can also be carried by the manufacturer of the
product, for this please contact the manufacturer.
