QUESTION:  
Can I Order A Spare Part Transmitter For My Sitrans Fue380 System Without Loosing The System Verification?

ANSWER:  
Check the MLFB combination of your system.
The number in question is placed in position 12.
Example: 7ME3410-1KE42-3ET2. (xxxxxxx-xxxx2-xxxx)
If the number in position 12 is 0, 1, 3 or 4 you can order a spare part transmitter without loosing the system verification.
If the number in position 12 is 2 or 5 you cannot order a spare part transmitter without loosing system verification.
Contact Siemens Customer Support in order to find a solution if your transmitter has stopped working and cannot be replaced by a spare part transmitter.
