0-10 V beacon lighting regulation

Each LPS unit output circuit is configured as "maintained / non-maintained”. This operating mode is assigned to all non-electric line communication (non-ELC) luminaires connected to said circuit.

If luminaires with electric line communication (ELC) are used, the "maintained / non-maintained" operating mode is individually configured on each luminaire and is independent of the circuit configuration.

The DaisaTest application (through the LPSLan communication accessory) can monitor and control an indefinite number of devices.

Monitoring and configuration of communicating ELC circuits and luminaires

Execution of actions and scenarios

General system information

The monitoring unit controls the most critical aspects of safety (EN-50171) of the LPS units such as the status of the battery-charging rectifier, the general condition of the central battery, the status of the output circuits and runs functional, duration and battery capacity tests. It controls the charge voltage and current of the batteries and their temperature.

A control panel with graphic LCD display enables data monitoring and performs the following configuration tasks:

Definition of the central battery’s duration.
Configuration of the circuits in maintained / non-maintained mode.
Configuration of the frequency of the tests, day of the week, test schedule, automatic/manual mode.
Input configuration.
Output circuit configuration.
Display of scenarios programmed with winCBS or web server.
Zoning of communicating luminaires (ELC).
Operational configuration of ELC-type luminaires (maintained/non-maintained)
Display of ELC-type luminaire status.
Internal memory with central battery configuration log, test results and status of ELC-type luminaires.

LPSLan communication module.
Communication module via Ethernet connection with integrated web server. Enables monitoring of the central battery and ELC-type luminaires.

DR-3 remote detector.
Network fault detector for centralised LPS series units.
Monitors the status of the network (3 phases and neutral) which it shows by flashing a front-mounted LED (off during network downtime).
It has two contacts (NO, NC) connected to the LPS central battery auxiliary inputs and, in the event of a network fault, enables configuration of the output circuit start command.
