7.6.1
Response to faults
Description
In some cases, the device can be set in such a way that it responds to faults by either
issuing a warning or by tripping. Examples: "Response to asymmetry", "response to
temperature sensor overload".
The following table shows how the motor starter responds (depending on how it has been
parameterized):
Fault
Response 1 Response 2
Response:
Warning Trip
Message bit:
Group warning set Group fault set
LED display:
DEVICE flashes yellow DEVICE lights up yellow
SF lights up red
Motor and brake:
Not shut down Shut down
Note
With certain faults (e.g. "process image error" or device errors, such as "Switching element
defective"), however, the device always responds by tripping.
This response cannot be changed!
Other methods of indicating faults
Faults in the system can also be indicated as follows:
● When using Motor Starter ES, the relevant fault message appears in plaintext.
● On the fieldbus, the relevant bis is set in the cyclic message frame and/or on the
diagnostics channel.
7.6.2
Acknowledging faults
Restart after device-internal shutdown
If the motor starter trips the switching elements automatically, it does not restart until:
● The fault has been rectified
● The fault has been acknowledged
● Device function "emergency start" activated, that is, despite a pending group fault, the
motor can be switched on and off with the control commands (not in the case of a device
error!)
