3.2 CCR Module (Standard)
The modules are manufactured in three sizes, 40A, 60A and 110A.
The CCR Modules are constructed as plug-in units with connectors for easy maintenance.
The CCR Modules includes up to three printed circuit boards (Mainboard, Trigger board and
Profibus board), thyristor block, contactor, EMC components and fuses.
These elements are the main components in the CCR Modules.
On the front of the CCR Module, you will find:

Key switch (Remote – Off – Local)

Folia push bottoms

Display

LED indications

Data connection
Each CCR Modules includes a Memory board. This Memory board includes a set of standard
values for the adjustment of the CCR (Default Values). The Memory board do also include all
individual adjustment for the CCR Module, as well as specific data for the connected series
circuit.
If this Memory board is removed from one CCR Module to another, all data are moved
accordingly. The Memory board is placed in a socket on the Mainboard printed circuit.
This facility means that a spare CCR can be taken in operation, fully adjusted, in a few minutes.
Drawing 961.048 shows a block diagram of the CCR Module.
All communication internally are done via an I2C data buss. On the Mainboard is placed two

-
processors. These processors are handling the current regulation, supervision as well as
communication with the front panel (Local operation) or with the Remote Control. The Main
Board includes facilities for directly remote control in our RS485 serial protocol. If Profibus is
required, an additional Profibus board is included in the Module.
The following information can be added to the each single part (block) on drawing 961.048:

The Current Reference system.
As standard, the CCR has seven “normal” light intensity steps. These steps can all be
adjusted to any current value between 2,2A and 6,6A.
Besides, the CCR has a special step 8 (SW version 2.14y or later), designed for special
purposes, such as
o
Heating of lamps / fixtures without any light output
o
Interlock current step, or a “safe” current value. The step can be used in connection
with for instance large load changes.
o
Particular critical circuits can be permanent supervised for lamp- or isolation
failures without lighting the circuit.
o
For Stopbarre circuits frequently switched on and off, to reduce number of
contactor operations.

The Analogue measuring system:
The following analogue values are converted to digital data:
o
The current in the series circuit (0 – 6,6A via current transformer 7,5A/0,25A)
o
Mains (230V or 400V via voltage transformer 400V/10V)
o
Output voltage (0 – 5000V, measured on the primary side of the Power transformer
via voltage transformer 400/10V, multiplicated with the voltage ration of the
Power transformer)
o
The isolation level of the series circuit to ground, measured from 0

to more than
2M

via ISO measuring box with 500VDC measuring voltage.
