Frangibility
The mounting support of the equipment is not frangible, due to the mass of the equipment cabinet and the electrical cables.
Install the equipment outside the safety area of the approach. This means there is an increase in distance between the
equipment and the flasher head. The equipment compensates for losses in the cable between the flasher head and the
equipment, provided that that you use cables with the correct cable cross sections.
FCU PCB
The FCU PCB in every equipment:
•
Receives input messages from the LMC and is connected with the separate equipments through the local bus connection;
•
Charges the flash capacitor;
•
Monitors the discharge current and misfires through the lamp;
•
Enables three lamp brightness levels to be adjusted.
LMC
Each equipment operates as a slave and is connected to a LMC. For a description of the LMC, see §
Local Master Controller
(LMC) description .
Lightning protection
The equipment cabinets may have an over-voltage protection (option). All metal parts are interconnected and the cabinet
includes earthing lugs for an earthing connection. You can add an optional overvoltage protection for areas with a high risk
of lightning.
Local bus connection board
The local bus connection board interconnects all the devices of a system as a part of an RS-485 protocol. Inside the
equipment cabinets, the equipments are pre-connected at delivery. The interconnection of all equipment cabinets in a
flashing system must be realized with a screened dual twisted pair connection.
The local bus connection board has a set of gas arresters that provide over-voltage protection for the local bus wiring.
3.5 Local Master Controller (LMC) description
The LMC controls a complete flashing system and interfaces to remote controls. The LMC is the interface between the control
system and the flashing system.
The LMC makes it possible to:
•
Monitor and configure the whole flashing system from any cabinet in the system with a configuration software tool and
PC, if you purchased this option.
•
Measure and control the temperature of each cabinet.
•
Receive a signal if the micro switch of the flasher unit or the cabinet door is open. In this case, the flasher capacitor is also
discharged.
•
Receive MOV signals.
•
Regulate the flashing rate and intensity.
•
Control the status of all the connected equipments.
An internal temperature probe is installed on the LMC connector.
Location
The LMC is a PCB installed in the cabinet door of any equipment cabinet in the flashing system. It is recommended to install
the LMC in an equipment that you can easily access for maintenance.
