Trip Reset; Self-Test - Siemens SIRIUS M200D Manual

Trip reset

Trip reset acknowledges all the errors/faults that are currently present in the starter and that
can be acknowledged. An error/fault can be acknowledged if its cause has been rectified or if
it is no longer present.
The trip reset can be triggered by:
● Remote reset via the bus interface (DO 0 CW ON and DO 1 CCW ON simultaneously,
both edges in the same AS-i cycle)
● Remote reset via input action (if parameterized)
● Local reset via the device interface (hand-held device or ES tool)
● Local reset via the key-operated switch (0 position; order variant)
● Power ON reset (24 V DC PWR supply switched off and on again) only if protection
against voltage failure is deactivated (parameterizable).
● Reset via disconnecting means
Please set the rotary switch from 0 to 1 for this purpose.
You can find more detailed information in Acknowledging faults (Page 142).

Self-test

Description
Two types of self-test can be carried out:
● Self-test at switch-on
This is automatically selected when the device is switched on or initialized.
● Self-test during operation:
The motor starter cyclically monitors specific device components and signals any errors
(device errors).
Test steps
The self-test involves 3 test steps. These steps are carried out in relation to the signal
duration of the test command:
Test step
