2.15 SHUT DOWN PROCEDURE
If the sample stream contains corrosives or solvents it is good practice to purge the sample
pipelines of the analyser with dry nitrogen or instrument quality air for 12 hours before
switching off the analyser. This will prevent the possibility of condensation and subsequent
corrosion in the measuring cell.
Before servicing the analyser all external sources of power including those to relay contacts
must be disconnected.
Note: For earlier analysers fitted with a battery backup the batteries should be removed to
prevent leakage and corrosion, if the analyser is to be taken out of service and stored
for a period of more than 6 months.
2.16 SAFETY PURGE OF CONTROL UNIT
The Control and/or Interface unit may be purged to provide hazardous area safety. Figure
2.19 shows location of the purge connections.
Servomex can supply an analyser complete with certified purge system. See manual
00480001A for complete installation and operating instructions.
