8.3.1 Control module CU-S
+
The operation of the control module is described in detail
in the following pages.
8.3.2 DC/DC Converter
This module supplies the electronic controlgear in the
switch cabinet with the necessary operating voltages
(24V and 6 V DC). The LEDs light up when the voltage
supply is present.
8.3.3 SU-S
+
of the final circuits
The SU-S
+
module monitors emergency luminaires with
electronic ballasts. Die STAR
+
technology checks the
function of the luminaires that are connected to it. Up
to 20 luminaires per circuit can be connected. Mixed
operation within a circuit of maintained light, switched
maintained light and non-maintained light is possible.
No
additional data cable is required.
– freely programmable for maintained light, switched
maintained light or non-maintained light;
– easy access to fuses (1) at the front of the module;
– LEDs (2) for fault and run RUN/ON for each circuit;
– service button (3) for direct display of module status as
a plain language readout on the control module

8.3 Controls and displays on the modules
All of the modules in the switch cabinet have LEDs that
indicate the operational status of the assigned functions.
Red LEDs indicate that the assigned function is in fault or
that a malfunction has occured. If no LED lights up on a
module then module´s supply may be interrupted.
NOTE
The CU-S
+
control module has numerous diagnostic func-
tions and operating menus for analysing and remedying
malfunctions. You should use and analyse these options
before attempting work on the fuses of modules or final
circuits. The following instructions must be followed
without fail!
WARNING!
Work on the electrical installation may only be
carried out by qualified electricians with training
in the lighting and emergency lighting system .
When replacing fuses, use only the type and rating
as indicated on the module or in its technical
documentation .
There is also danger of electric shock or short circuit
when working on final circuits that have not been
isolated first .
You should also bear in mind the possible effects
on the lighting in parts of the building when you
interrupt the supply to final circuits .
