Explanation
/Action
E2
Low transmission
The system has been in transmission pending mode for
too long. In transmission pending mode the analyzer will
only regulate the laser temperature from the calculated
drift.
Ensure sufficient transmission by cleaning optical
surfaces and re-alignment of the sensors.
E3
Receiver power
The power supply to the receiver is interrupted or not
sufficient.
Check the cabling to the receiver.
E4
Receiver junction power
The power supply to the receiver is interrupted or not
sufficient.
Check the cabling to the receiver.
E5
Transmitter power
The power supply to the transmitter is interrupted or not
sufficient.
Check the cabling to the transmitter.
E49
Transmitter board temperature
Transmitter board temperature outside valid range.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E50
Receiver board temperature
The receiver board temperature is outside the valid
range.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E51
Laser board temperature
The laser board temperature is outside the valid range.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E52
Detector board temperature
The detector board temperature is outside the valid
range.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E53
Receiver junction board
temperature
The receiver Junction board temperature is outside the
valid range.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E54
Laser vibrator temperature
The vibrator temperature is outside the valid range.
Check that the ambient temperature is within the
specifications and ensure that the system is not exposed
to direct sunlight.
E62
Hardware Inconsistency
Mismatch between receiver and transmitter versions e.g.
when either the receiver or the transmitter has been
replaced.
Contact Siemens support.
E65
Laser drift
The laser is getting close to the limit of operation.
Contact Siemens support.
