4.2 Product Description
The AT-S
+
automatic test system is a symbiosis of STAR
and CEWA GUARD technology, and now also enables
the monitoring and specification of switching mode of
the connected emergency lighting in networks using an
aggregate, dual network or central converter with 50 or
60 Hz AC voltage as supply voltage as power sources for
safety services.
The main benefits of this technology include the fact that
•
within a final circuit, the switching modes
– Non-maintained light (Emergency lighting is switched
on when the main lighting fails or when a function test
is initiated manually or automatically)
– Maintained light and (Emergency lighting is always on)
– Switched maintained light (as non-maintained light
with emergency lighting controlled by switch queries,
e. g. from external DLS-modules)
can be implemented in hybrid mode for each emer-
gency luminaire.
•
each safety and EXIT luminaire can be programmed
without an extra data cable,
•
the switching modes can be later modified without the
need to interfere in the existing luminaire installation.
The functions of the emergency luminaires are defined
with a user-friendly parameter setup system.
The use of V-CG-S type ballasts/modules is a require-
ment.
All settings are stored in a nonvolatile memory and so are
not lost even in a total shutdown situation (230V mains
supply).
Parameter settings and the names of circuits, luminaires
and DLS/TLS-modules as well as test log entries can also
be stored on a memory card. As well as archiving, this
also allows (optional) external parameter setting and trans-
fer to control modules of the AT-S
+
system.
Aggregates, dual networks and central converters supply
the energy for operation of the emergency lighting upon
failing of the power supply via the general 230V mains
grid. During normal operation, the AT-S
+
system monitors
the functionality of the connected emergency lighting.
The system AT-S
+
is designed and manufactured in
compliance with the following EC directives:
•
Low-voltage Directive 2006/95/EG
•
Directive 2004/108/EG on electromagnetic compatibility
•
National (DIN-), European (EN-) and international (IEC-)
standards which the system complies will be found in
the system´s CE Certificate of Conformity.
4.3 Operation Modes
Different system configurations are used depending on
the requirements of the site. These standardised configu-
rations have names like
AT-S
+
C30 or AT-S
+
C16
for operation of max. 30 or 16 SU-S+ 2x6A circuit
modules with 60 or 32 optional circuit terminals. Up to 6
AT-S
+
substations can be supplied with mains current (up
to six lines with 1-phase substations, up to two 3-phase
substations).
AT-S
+
C4
for operation of max. 4 SU-S
+
2x6A circuit modules with
circuit terminals. Up to 4 lines with AT-S+ substations can
be supplied with 1-phase mains current.
AT-S
+
C0
for operation of max. 2 CU-S
+
control units. For monitoring
of up to 40 SU-S
+
/ SOU-S
+
circuit modules per control
unit via the RS 485 bus.
AT-S
+
SU4, AT-S
+
SU2, AT-S
+
SU1
for operation of 4, 2 or 1 SU-S
+
2 x 6A circuit modules
with 8, 4 or 2 circuit terminals.
AT-S
+
SOU2, AT-S
+
SOU1
for operation of 2 or 1 SOU-S
+
2 x 4A circuit modules,
with 4 or 2 circuit terminals and supplementary mains
feed for rental current counting.
All devices and substations are constructed modularly. The
technologies of changing-over and of monitoring form a
unit working undependent from each other, so that interac-
tions can be excluded. Due to the modular construction
and the pre-configured modules a flexible and high quality
handling is ensured. The objective of the automatic test
system is to secure the function standby of all connected
emergency and exit luminaires by an automatic monitoring.
