Additional equipment

It is possible to add additional equipment/components to a mounting rail in the left hand part of the
analyzer. The following points must be observed:
- The mounting rail is approx. 250 mm long which limits the number of components which can be
installed.
- The max. installation height incl. mounting rail is 115 mm, but it is less in the vicinity of the display
(approx. 88 mm). The width should not exceed 100 mm.
- The additional equipment must be licensed for an ambient temperature of 60 °C, this temperature
can be reached under extreme conditions.
- The Ex protection types of the retrofitted components must also be specified on the analyzer.
- Installation must always be agreed upon with the Ex specialist responsible.
6. Maintenance
Following maintenance or the retrofitting of parts associated with explosion protection, the analyzer
may only be started when an Ex specialist has ensured that the analyzer has the essential features
and meets the requirements for explosion protection and issues a certificate to this effect or has
attached a test symbol to the equipment.
Annual maintenance of the analyzer must be carried out to check the electrical safety and reliable
operation, in particular the tightness of the sample gas path within the analyzer.
The owner can extend the maintenance interval in individual cases if no negative influences can be
expected with respect to chemical corrosion of the wetted parts materials (gaskets in particular).

Recommended test setup for CALOMAT 6F and OXYMAT 6F

2,4 = connections for sample gas path
3 = connection for reference gas (if present)
Bl = blanking plugs
Fig. 1: Setup for testing for leaks in the sample gas and reference gas paths
- Reference gas connection 3 (if present) and sample gas outlet 4 must each be closed by a
blanking plug. A shut-off valve (e.g. needle valve) of sufficient tightness must be connected
between sample gas inlet 2 and the sample gas line.
-
A pressure sensor with a measuring range of 2000 hPa (O 6F) or 50 kPa (C 6F) and a resolution
of 1 hPa must be connected to the supply line.
