LEDs "S3"
Meaning
Status of Sercos III Communication. (In the variant L10 without func‐
tion)
Fig.7-7: "FS" and "FN" LEDs
LEDs "RI"
Meaning
Off -
Green Local bus active

The 7.5 V Inline voltage U
L
and the +24 V analog voltage U
ANA
are derived from
the external +24 V voltage U
LS
.
24 V Supply Voltage ULS
The
internal voltages
required in the IndraControl L10 are generated from the
24 V supply voltage U
LS
(terminal 1.2).
U
LS
is electrically isolated from the voltages U
M
and U
S
.
Requirement: A power supply unit that is electrically isolated from
the power supply units for U
M
and U
S
is used for U
LS
U
M
and U
S
are not electrically isolated from each other.
+24-V Supply of Main Circuit UM
The 24 V
voltage for supplying the main circuit U
M
that is to be fed in at terminals
2.1 and 2.2 is not used in the IndraControl L10.
The main circuit U
M
starts at the IndraControl L10 or at a power terminal and is
supplied through all following modules up to the next power terminal. At the
next power terminal, a new circuit is started; its potential is isolated from the
previous one.
Several power terminals can be used within one station.
