I.6 SUB-ASSEMBLIES
I.6.1 LOAD ADAPTATION
The main function of the load adaptation device is to adjust the power of the CCR to the installed power
of the lighting loop..
This tapping can be accessed from the back of the CCR, dismonting the rear panel.
I.6.1.1 Adaptation to load:
The transformer comprises output terminals which allow load settings from 12.5% (1/8 load) to 100%
(4/4). Six insulated terminals are used for this depending on the transformer.
I.6.1.2 Automatic load plate position computation:
An input current transformer is added in the primary power supply to compute automaticaly the position of
the load plate when it changes. With this option, it is not necessary to set the load plate value each time the load
plate value changes.
You can see the load plate value in the menu "Monitoring"

I.7 OPTIONS
I.7.1 EARTH FAULT DETECTOR (EFD)
This option is used to measure the insulation of the load with respect to earth.
The insulation controller, or “earth fault detector” continually checks the electrical resistance between
the loop and earth. It uses the principle of continuous current injection at 500V and its range of measurement is
between 1 k

and 65 M

.
The insulation resistance value can be seen in the “
Monitoring
” menu
Two comparison levels (warning and alarm) are available. They are preferably set at 1M

and 100k

.
Setting the Level EFD1 and Level EFD2 parameters:
Go into the menu “ Alarms and Warnings” then “
Earth fault
”.
Remote indication :
•
Each level passed is indicated by a contact relay
•
The insulation resistance value, levels and warnings are transferred to the Jbus table.
