)
2.3 PGND (ground main and segment voltage)
Fig.7-3: Pin assignment on the voltage terminal
Malfunction if contacts 2.1 and 2.2 are inter‐
changed
NOTICE
Controls with a device index smaller than 201 (e.g. parts number:
R911170899-104) have the the contacts 2.1 and 2.2 changed.
Five LEDs are arranged at the upper edge. The LEDs have the following mean‐
ing:
LED "U
M
" Meaning
Off Main circuit supply is missing.
Green 24 V supply U
M
of the main circuit is present.
Fig.7-4: Diagnostic LED of the power terminal
LED "U
S
"
Meaning
Off Segment circuit supply is missing
Green 24 V supply U
LS
of the segment circuit is present
Fig.7-5: Diagnostic LED of the segment terminal
LED "U
L
"
Meaning
Off Supply voltage U
LS
is missing
Green 24 V supply voltage U
LS
is present

LEDs "FS" and "FN"
Meaning
- Currently without function

The 7.5 V Inline voltage and the +24 V analog voltage U
ANA
are derived from
the external +24 V voltage U
LS
.
24 V Supply Voltage U
LS
The 24 V supply voltage U
LS
(contact 1.2) generates the internally required
voltages in the IndraControl L45/L65/L85.
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.
