6.6.1 DLS/3Ph-Bus-Module
If possible these modules should be installed direct in
the sub-distribution boards which supply the associated
circuits (for the general lighting or stairwell lighting). This
is advisable because it means that only one bus cable
needs to be run (to RS 485 connection on the CU-S
+
control module) between the external modules and the
related controller (in the AT-S
+
cabinet or its substations).
The cables for the 24V supply for the bus modules can be
laid with a 4-core cable together with the bus.
The 24V supply and the bus cable can now be looped
through inside the sub-distribution board on the devices.
In many cases it is desirable to all controlgear to be
concentrated in a single control cabinet (e. g. for the
central operation and monitoring of all switching elements
and circuits). For such requirements CEAG can supply a
preassembly for fitting DIN mounting rails in the cabinet
AT-S
+
to which external modules can then be mounted
(accessory part no. 400 71 347 125). With this type of
assembly a cable must be run between the cabinet and
the distribution board for the mains supply (of the moni-
tored circuits) for each command.
You will find the block connection diagram and further
technical information on the page 26.
The terminal assignment will be found on the device. The
terminals can accept cables up to 2.5mm² cross-section.
Terminal assignment on the DLS/3Ph-bus-module
(top/bottom) X = terminal not assigned
Terminal assignment on the TLS bus module
(top/bottom) X = terminal not assigned
The supply for the glow lamps in the light pushbuttons
is connected to the upper terminal strip on the module,
terminals N (O) and L (U); the PE terminal is also
connected to the PE terminal of the SU or SOU!
6.6.2 TLS-Bus-Module
If possible these modules should be installed direct in
the sub-distribution boards which supply the associated
circuits (for the general lighting or stairwell lighting).
They can be mounted in the AT-S+. Otherwise the same
criteria for selecting the installation position apply as for
the DLS/3Ph bus modules.
You will find the block connection diagram and further
technical information on page 24!
