Fault removal
8.1
General information
The following chapter describes a number of possible problems that the user can
partially remedy independently. If such problems occur frequently, the Service
department of Analytik Jena GmbH must always be informed.
As soon as the multi N/C pharma UV is switched on, system monitoring takes place.
Any errors occurring are displayed in a window after start-up. Starting a measurement
is not possible.
The user must acknowledge the error messages by clicking the button [OK]. Next a
message text opens in the main window and possibly the button [I
NITIALIZE ANALYZER
]
.
Before starting a measurement a flow control is always carried out. A flow error is
registered as soon as the actual flow differs ±10 ml/min from the target flow. In case
of a flow error the UV lamp switches off.
In standby mode the measuring gas flow is lowered below the minimum flow, the UV
lamps switches off for safety reasons.
For fault analysis it is possible to record log files. The recording of log files should be
enabled after consultation with the Analytik Jena GmbH service department for
specific faults. The log files are stored in the directory …\multiWin\LOG. For fault
diagnosis the complete directory …\multiWin\LOG must be emailed to the Service
department of Analytik Jena GmbH (see Service address on the inside front cover).
The following files can be generated and saved:
