6.3.5 Low Level Outputs "LL out" for External Amplifiers
Note: The low-level outputs "LL out 7 - 12" are only available, if the option
LLO-2 is installed, refer to section 6.11, "Option LLO-2 (Low Level Outputs)"
on page 90.
Both SELV interface connectors "LL out 1 - 6" as well as the optional
"LL out 7 - 12" (if applicable) hold two independent generator triples each.
These six high accuracy analog signal sources per connector can serve to
either control an external amplifier or to directly provide small signal outputs.
In addition, each SELV interface connector provides a serial digital interface
(pins 8-16; see below) that transmits control and monitor functions between
the
CMC 356 and the external amplifiers. Supported devices are the
CMA 156 , CMA 56 , CMS 156 , CMS 251 and CMS 252 (see also 9.6.7,
"CMLIB A" on page 119 and 9.6.9, "Connection Cable for REF 54x Relays
(ABB) with Low Level Signal Inputs" on page 121).
The low level outputs are short-circuit-proof and continually monitored for
overload. They are separated through reinforced insulation from the power
input and from the load outputs (SELV interface). They deliver calibrated
signals in the range from 0 to 7 V
eff
nominal (0 to ± 10 V
peak
).
Both the selection of the particular amplifier as well as the specification of
the range of the amplifier takes place in the
Test Universe software.
