Options
L82
3 x 2 thermistor protection relays for alarm and fault
Option
L81
offers six thermistor protection relays (with PTB
approval) for PTC thermistors (type A) for warning and discon-
nection. The power supply for the relay and the evaluation is
provided within the converter.
An additional TM31 Terminal Module is integrated as interface
for further processing and to display signals.
Note:
Option
L82
cannot be combined with option
G61
(additional
TM31 Terminal Module).
L87
Rotor ground-fault monitoring
(static excitation unit, see Accessories, Chapter 7)
Option
L87
provides integrated ground-fault monitoring for the
rotor circuit.
L90 to L96
Three Pt100 inputs are available in the standard version. As a
consequence, together with one of the options
L90 to L96
the
following maximum number of Pt100 inputs can be achieved:
•
SINAMICS GM150 in the IGBT version: 9 (with
L91
,
L93
or
L95
)
•
SINAMICS GM150 in IGCT version and
SINAMICS SM150 in IGCT version: 15 (with
L94
or
L96
)
L90
Pt100 evaluation unit with 3 inputs
The Pt100 evaluation unit can monitor up to three sensors.
For all three sensors, the limits for alarm and disconnection must
be set centrally.
The output relays are integrated into the internal fault and shut-
down sequence of the converter.
An additional TM31 Terminal Module is integrated as interface
for further processing and to display signals. The terminals that
are assigned for the Pt100 evaluation are listed in the following
table.
Note:
Option
L90
cannot be combined with option
G61
(additional
TM31 Terminal Module).
The sensors can be connected using a two-wire or three-wire
system. In a two-wire system inputs xT1 and xT2 must be as-
signed and a jumper inserted between terminals xT2 and xT3.
