S4A software can be downloaded from our Web site M599 7020 7.
Installation 7.2 Electrical connection The flow sensor is equipped 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 operate the S 418 one cable connection is sufficient however if the pulse output is to be used or the supply and signal should be on separate cables a second connection cable has to be ordered.
Installation ATTENTION! Do not screw the M8 plug using force. Otherwise, it may damage the connecting pins. 8 Sensor signal outputs 8.1 Analog output The sensor has an analog output range of 4 ... 20 mA. This output can be scaled to match a desired measuring range. Standard scaling is from 0 to the max flow. The corresponding flow in different pipe sizes can be found in Appendix A. 8.2 Pulse output The sensor will send out one pulse per consumption unit.

Configuration 9 Configuration To change any settings on the S 418, please download and install the service App S4C-FS which is available on the Google Play store or our Website. This App runs on any Android system with BlueTooth supported. To be allowed to change settings, the App needs to scan the QR code on the calibration certificate at first. This ensures that only valid users can access the sensor settings. For more information about instructions, see the S4C-FS Instruction and operation manual.
Data logging 10 Data logging The S 418 provides the data logger function to help you record and analyze data measured over time. 10.1 Features Before you use the data logger, learn about how it works: • You can use the Android App S4C-FS to enable or disable the data logger function and set a sampling rate as needed. • By default the data logger is disabled. Once you enable the data logger, the S 418 starts logging data. Once you disable the data logger, the S 418 stops logging.
Data logging 10.2 Operations 10.2.1 Logger settings Control and configure the S 418 data logger through the S4C-FS App. 1. Install and launch the S4C-FS App. For more information, see the S4C-FS Instruction and Operation Manual. 2. Access Settings > Logger Settings to perform all logger-related operations as listed below. Parameter Description Logger Status To start or stop the logger. Start Date & Time To view the time stamp of the first log recorded.
Data logging 6. Click the File menu to have graphic views on measurement data in a log file; and if needed, to export this log file to the Excel or CSV format. For more information about operations on S4A, click the Help button on the top right corner.
Calibration 11 Calibration The sensor is calibrated ex work. The exact 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 excluded from the instruments warranty.
12 Warranty The warranty is canceled: • If the user opens the measurement instrument without a direct request written in this instruction manual. • If repairs or modifications are undertaken by third parties or unauthorized persons. • If the serial number has been changed, damaged or removed. Other claims, especially those for damage occurring outside the instrument are not included unless responsibility is legally binding. Warranty repairs do not extend the period of warranty.

Appendix C LRC and CRC calculation 16 Appendix C LRC and CRC calculation LRC generation The Longitudinal Redundancy Checking (LRC) field is one byte, containing an 8–bit binary value. The LRC value is calculated by the transmitting device, which appends the LRC to the message. The device that receives recalculates an LRC during receipt of the message, and compares the calculated value to the actual value it received in the LRC field. If the two values are not equal, an error results.
Appendix C LRC and CRC calculation static unsigned char LRC(unsigned char *auchMsg, unsigned short usDataLen) { unsigned char uchLRC = 0 ; while (usDataLen––) uchLRC += *auchMsg++ ; /* LRC char initialized */ /* pass through message buffer */ /* add buffer byte without carry */ return ((unsigned char)(–((char)uchLRC))) ; /* return twos complement */ } CRC generation The Cyclical Redundancy Checking (CRC) field is two bytes, containing a 16-bit binary value.
Appendix C LRC and CRC calculation 8. When the CRC is placed into the message, its upper and lower bytes must be swapped as described below. Placing the CRC into the message When the 16-bit CRC (two 8-bit bytes) is transmitted in the message, the low-order byte will be transmitted first, followed by the high-order byte.
