3.1.5 Controller - sensors communication
The sensors communicate with the controller via CAN bus using diagnostic mechanisms in compliance with
standard EN 50325-5 to guarantee SIL 2 and PL d.
For correct functioning, each sensor must be assigned with an identification (ID). Two sensors on the same
bus must have different IDs.
The default settings for the sensors is ID = 0, or no assigned ID.
3.1.6 Applications
LBK System integrates with the machinery control system: when performing safety functions or detecting
failures, LBK System de-energizes the safety relays and keeps them de-energized, so the control system can
command safety conditions of the area and/or prevent restarting of the machinery.
In the absence of other control systems, LBK System can be connected to the devices that control the power
supply or machinery start-up (e.g. external relays on the power supply line).
LBK System does not perform normal machinery control functions.
For connection examples, see "Electrical connections" on page63.
3.2 Controller LBK-C22
3.2.1 Functions
The controller performs the following functions:
l Collects information from all the sensors via CAN bus.
l Compares the position of detected motion with the set stopping and pre-alarm thresholds.
l De-energizes the safety output relays when at least one sensor detects motion in the stopping area.
l De-energizes the safety output relays if a failure is detected in the sensor or the controller.
l Manages the auxiliary inputs and outputs (to learn about the functions see "Auxiliary outputs" on the
next page and "Digital inputs" on the next page).
l Communicates with the Inxpect Safety software for all configuration and diagnostic functions.
