3 System Description
3.1 System Overview
A KY-LOC 1D.02.01 system consists of two units that conduct a range measurement between
each other. The two units are using the time of flight of the Radar signals to measure a precise
distance between each other. The units can be configured to receive the distance values on
one unit or on both units. The units must be configured as Relay and Remote devices, as
explained in chapter 6. By default, the Relay device does provide access to the information
relevant to the distance measurement, while the remote device is only used for measuring
purposes. However, is an option to have the same information on the Remote device if it is
configured accordingly, as described on chapter 6.
Both units need to be powered with either DC power supply or PoE (802.11af). The unit, where
the range measurement is requested, needs to be connected via a data interface, either
Ethernet or RS-485. Figure 1 shows the complete system including mounting bracket for
mounting on any suitable structure. If other interfaces are necessary, e.g. ProfiNET, ProfiBus,
Ethernet/IP, ModBus, can be provided via the KY-XTRA B interface devices.
For FCC and CA, the system is for fixed operation only. This includes
installation in fixed equipment, even if the sensor itself moves within the
equipment.
3.2 System Technical Data
For the technical data please refer to the Datasheet of the device (refer to RD-1). The latest
datasheet can be downloaded from the KYMATI webpage (www.kymati.com)
3.3 Range Measurement & Range Computation
To perform a range measurement between two devices, they need to be synchronised.
Therefore, the Relay device sends out a synchronization signal and the Remote synchronizes
onto that signal. When the devices are synchronized, they start automatically with the range
measurement and stay synchronized. Additionally, the front LEDs are used to show whether
the devices are synchronizing or synchronized, for more information please refer to chapter 4.
If the devices lose their wireless connection to each other (e.g. object in between) for a long
time, they will automatically re-synchronize.
