TROUBLESHOOTING AND CLEARING MALFUNCTIONS
10.3 Integrated monitoring and diagnosis system
The GM35 is equipped with an integrated system that constantly monitors the operating
state of the SR-unit and evaluation unit. Appropriate messages are generated and logged
in the devices for subsequent evaluation should any deviations from normal operating
states occur.
Messages for the two system components are categorized into error messages and
warning messages depending on the anticipated effects:
• Warning messages are generated if the measurement results are not (yet) directly
affected by the change in the system state. Nevertheless, it is important that the cause(s)
be investigated and corrected, e.g. by means of maintenance measures, to avoid further
malfunctions and damage to the device in particular.
• Error messages are generated when measuring operation is no longer possible or no
longer reliable.
These warning and error messages are stored in the integrated message memory of the
evaluation unit.
Message signaling and retrieval on the evaluation unit
* The relay is active during normal operation (no malfunction), i.e. the contact is closed.
Procedure
Troubleshooting Table If a warning or malfunction is signaled, first call up pending error messages in the Error
menu. Then localize the possible cause and clear the malfunction; see Troubleshooting
Table.
