Description
S-lynks is a complete solution for continuous infrastructure monitoring. It analyzes the behavior of the structure and detects anomalies which makes it a great tool to meet the growing requirements for predictive maintenance programs. This fully integrated system can be installed permanently on the structure and the data collected is immediately transmitted to a secure software platform. The S-lynks solution is intended to conduct an audit or monitor the state of health of a structure. The wireless acquisition and transmission of data and their frequency can be configured using a field terminal and a Powerstick or via the online service platform (for a permanent monitoring). The Nodes are powered by Sercel battery pack that can be replaced.
S-lynks Gateway
The S-lynks Gateways collect the data transmitted by the Nodes positioned on a structure. The Gateway is installed at the location where its data collection is the most optimal in order to maximize energy performance. The data collected is sent over the field terminal (for an audit) or over the online service platform (for a permanent monitoring). The Gateway is powered by an external power supply and has an internal backup battery in case of temporary failure of the external power supply.
Functions:
· Interact with nodes (PN 10046233) · Dual mode operation: Audit or Monitoring · Using GNSS reception, it ensures synchronization through radio transmission to nodes. · Transmit radio order and parameters to nodes · Wirelessly retrieves data from Nodes (raw acquisition data, status and QC) · Transmits processed data and raw data (if applicable) to the Cloud · Transmits status and QC to the Cloud · Request order from Cloud · Allows data acquisition to be retrieved manually on a compatible terminal via Wi-Fi or Ethernet (see
compatible terminal section) · Provide batteries status with battery pack compatible (including Gauge) External connections:

S-lynks-Nodes The S-lynks Nodes contain the QuietSeis® technology in order to acquire accelerometry data once positioned on a structure. The Nodes are installed directly on the structure to be monitored. The X, Y and Z axes are visible on the front face of the case in order to represent the orientation of a Node in space. The wireless acquisition and transmission of data and their frequency can be configured using a field terminal and a Powerstick (for an audit) or via the online service platform (for a permanent monitoring). The Nodes are powered by a battery pack that can be replaced.
Functions:
· Interact with Gateway (PN 10046316) · Dual mode operation: Audit or Monitoring · Acquisition of 3-component ambient vibration time data (raw data).
– Sampling rate: 4ms – Duration: 20mn (Monitoring mode) or selectable up to 1hour (Audit) · Wirelessly transmit data (raw acquisition data, status and QC) to Gateway · Allows manually data to be retrieved wirelessly on compatible terminal

Position the Gateway In order to reduce the risks of poor transmission between the Gateway and the Nodes, the latter must be positioned at the most equidistant location from all of the Nodes positioned on the structure.
1. Check the green blinking signal indicating that the Gateway is turned on. If this is not the case, turn on your Gateway by placing a Powerstick on the turn on symbol located on the front face of the case.
2. Position your Gateway on the structure in a stable position. The front face of the case of the Gateway (the one with the serial number of the Gateway) must imperatively be turned towards the sky for good GNSS coverage.
Support plate PN 10051066 included:
In the absence of GNSS coverage, data acquisition cannot be carried out.
CAUTION
Position the Nodes Before positioning the Nodes, check that the latter are still turned on by checking for the presence of the green blinking signal at the base of the case. If the signal is inactive, turn on your Node by placing a Powerstick on the return on symbol located on the front face of the case or send a Lora wakeup via the Gateway with the field terminal application. The nodes can be positioned anywhere on the structure, in a stable position. In order to carry out a valid data acquisition, the axes of the cases of the Nodes must be configured according to a common reference (reference example: River or other landscape element, road, building, etc.). This common reference will make it possible to define on which axis of the case the data acquisition will be carried out (X, Y, Z, -X, -Y or -Z) and to enter it via the application of the fuel terminal.
With support bar PN 10046676 included (x2):
Powering up the Nodes and Gateways
Use a magnetic power stick on the turn on symbol of the Nodes and Gateways for powering up or switch to configuration state.

Maintenance
To clean the metallic enclosure of the S-lynks, use only a dry cloth.
IMPORTANT
Electrostatic discharge: Use the following guidelines to provide a static-free repair station that will preclude any ESD-related damage to electronic circuits: · All spare parts (circuit boards and ESD sensitive devices) should be stored and transported in static- shielding bags. · Unless the repair station rests on a conductive floor, chairs or stools should rest on a grounded, rigid-type, staticdissipative floor mat. · Use a static-dissipative table mat. · Wear a static-control wrist strap or foot grounder. · Provide common-point grounding for all conductive items (including personnel and soldering iron tip). · To control the discharge rate and protect workers from electric shocks, both the table mat and wrist strap should be grounded through a 1-M resistor. The mat should be connected to the same earth ground point as the wrist strap. · Wear static-dissipative garments.
