Output relay K1 is used to signal when the "fault" limit value is reached at a converter binary
input; output relay K2 is used to signal when the "alarm" limit value is reached at a converter
binary input. Output relay K3 is used to signal that the evaluation unit is ready at the
customer terminal strip -X2.7 .8.
The power supply for the evaluation unit is taken from the internal control voltage.
Connection
Table 11- 15 N2-B41 – connection for evaluation unit PT100 resistors
Terminal
1T1-1T3
2T1-2T3
3T1-3T3
Max. connectable cross-section: 2.5mm2
Safe electrical isolation between the sensor/signal and power circuit must be ensured.
Commissioning
According to the description of the evaluation unit (see operating instructions under the
"Additional operating instructions" tab).
Parameter assignment
The system-specific circuit diagram shows which binary inputs at the converter unit are used
to evaluate this monitoring.
Here is an example of a possible parameterization of the evaluation in converter:
Set value r5310.10 at p2112 (evaluation, contact alarm at DIO5).
Set value r5310.12 at p2106 (evaluation, contact fault at DIO6).
See the operating instructions for the SINAMICS DCM DC Converter, SINAMICS DCM DC
converter List Manual, operating instructions for the SINAMICS DCM Cabinet, ChapterSignal
connections (Page 85), project-specific circuit diagram as well as operating instructions
under the "Additional operating instructions" tab.
Reaction
Applicable in the example above:
In the event of an "alarm", "external alarm 1" (A7850) is triggered.
In the event of a "shutdown", "external fault 1" (F7860) is triggered.
