L93
Pt100 evaluation unit with 6 inputs and 2 analog outputs
(outputs for display connected to the control)
The Pt100 evaluation unit can monitor up to six sensors. The limit
values can be programmed by the user for each channel.
In the standard setting, the measuring channels are divided into
two groups of three channels each. With motors, for example,
this means that three Pt100s in the stator windings and two
Pt100s in the motor bearings can be monitored. Channels that
are not used can be suppressed using appropriate parameter
settings.
The output relays are integrated into the internal fault and shut-
down sequence of the converter. Two freely programmable
analog outputs (0/4 mA to 20 mA and 0/2 V to 10 V) are also
available.
An additional TM31 Terminal Module is integrated as interface
for further processing and to display signals and analog outputs.
The terminals that are assigned for the Pt100 evaluation are
listed in the following table.
Note:
Option
L93
cannot be combined with option
G61
(additional
TM31 Terminal Module).
L94
2 Pt100 evaluation units each with 6 inputs and
2 analog outputs
(outputs for display connected to the control;
SINAMICS GM150 in the IGCT version and
SINAMICS SM150 in the IGCT version)
Option
L94
offers two Pt100 evaluation units as described under
option
L93
, enabling up to 12 sensors in total to be monitored.
Two additional TM31 Terminal Modules are integrated as inter-
faces for further processing and to display signals and analog
outputs. The terminals that are assigned for the Pt100 evaluation
are listed in the following table.
Note:
Option
L94
cannot be combined with options
G61
and
G62
(additional TM31 Terminal Modules), as well as with option
E86
(additional analog inputs).

The sensors can be connected to the Pt100 evaluation unit using either
a two-wire or three-wire system. In a two-wire system inputs Tx1 and
Tx3 must be assigned. In a three-wire system, input Tx2 must also be
connected (x = 1, 2 , ..., 6).
