LiteSUN Plus is an analyser which sends and receives an encrypted light signal over plastic optical fiber LiteWIRE. The signal received is analysed and if there are variations, it gives an alarm via a normally closed relay. Bends and movements of the fiber cable cause variations and generate alarms. Vibrations, on the contrary, don’t result in variations of the light signal, so no alarm is generated. This very feature makes the whole system particularly robust to false alarms, even in windy and rainy environments.
The level of sensitivity of LiteSUN Plus can be manually adjusted to be suitable for the environments and for the installation needs. The sensitivity range of LiteSUN Plus has been tuned to detect the mechanical stresses induced on the LiteWIRE plastic fiber when it is installed on the back of solar panels as an anti-theft system.
After an alarm, if the fiber has remained intact, the system re-sets automatically, adapting to the (new) position. Besides, the device auto-calibrates according to humidity and seasonal changes, requiring no further adjustments.
On request, LiteSUN Plus can be provided with a built-in Power Meter, which measures the loss of optical power of the signal (=attenuation) through the fiber. The Power Meter function helps the installer check if the plastic fiber LiteWIRE is being laid correctly during installation or if it needs re-positioning.
On request, additionally, LiteSUN Plus can be provided with an optical relay output for alarm signal. Either the electrical or the optical output can be used. If you choose the optical output, you’ll connect it with plastic fiber LiteWIRE to a special receiver. Plastic fiber carries alarm signal in any environment without any noises and without risks of ground loops or lightning.
