Explanation
/Action
The system is starting up. This alarm should disappear
when system has started.
During normal ambient conditions the SITRANS SL
should have started up within 5 minutes. Ensure that the
ambient conditions are within the specifications for the
SITRANS SL and restart the system if needed.
The SITRANS SL has failed to lock on to the built in
reference cell.
Ensure that the ambient conditions are within the
specifications for the SITRANS SL and restart the
system. If the fault remains, contact Siemens support.
Internal communication failure in the Receiver.
Restart the system. If the fault remains, contact Siemens
support.
Internal communication failure in the Receiver.
Restart the system. If the fault remains, contact Siemens
support.
Sensor connection cable communication failure.
Check that sensor connection cable is properly
connected and not damaged.
The SITRANS SL has stopped measuring to protect the
laser from getting too hot.
The system may have been exposed to an ambient
temperature higher than permitted. Check that the
ambient temperature is within the specifications and
ensure that the system is not exposed to direct sunlight.
Restart the system.
The curve fit algorithm fails due to laser drift.
Ensure that the ambient conditions are within the
specifications for the SITRANS SL and restart the
system. If the fault remains, contact Siemens support.
The line locking state machine ended up in a fault state.
Restart the system. If the fault remains, contact Siemens
support.
