SIRIUS 3RW44 manual
GWA 4NEB 535 2195-02 DS 06
Cause / Remedy
At least one bypass element is welded and/or at least one thyristor has shorted. This message is generated when
the control supply voltage is applied and the current flow is being measured (via the soft starter), but no start
1)
command has been issued.
Remedy: Contact your SIEMENS contact partner or Technical Assistance (see Chapter "Important Notes")
Thyristor in phase L1 has shorted. (This message is displayed when the start command is issued.)
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
Thyristor in phase L2 has shorted. (This message is displayed when the start command is issued.)
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
Thyristor in phase L3 has shorted. (This message is displayed when the start command is issued.)
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
The device memory is faulty.
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
Device has not yet been identified. It must be given identification data.
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
The version does not match the firmware.
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
The bypass contactor is welded or defective.
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
Option 1: The temperature sensor on the heatsink of the starter is not connected or is defective.
Option 2: 3RW4465 or 3RW4466 may have a defective fan on the front of the starter.
Remedy: For 3RW4465 and 3RW4466 only: Try to rectify the fault after a cooling time of approx. 30 to 60 minutes
by switching the control supply voltage off and then on again. If successful, check whether the fan on the front of
the soft starter runs when a start command is issued. If not, it may be necessary to replace the fan. (The fan on
the front of the starter and the fan on the bottom of the device must both be running in fault-free operation).
For all 3RW44 starters:
If switching the control supply voltage off and on again does not cause the error message to reset, contact your
SIEMENS contact partner or Technical Assistance.
The temperature sensor on the heatsink of the starter is defective.
Remedy: Contact your SIEMENS contact partner or Technical Assistance.
Note
Some error messages may be incorrect (e.g. Loss of phase L1, although L2 is
missing).
Note
When using the 3RW44 soft starter in an IT system with ground fault monitoring:
3RW44, product version 
must not be used in this network configuration. 3RW44 soft starters from product
version *E07* onwards can be used in combination with the PROFIBUS DP
communication module. However, phase voltage values (UL-N) and phase-to-
phase voltage values (UL-L) may be displayed incorrectly on the measured
value display of the 3RW44.
1) Possible ohmic value for a defective thyristor: <2 kOhm (L-T).
