7.4. Replacement I/O Boards
If a replacement board E/A internal or E/A external becomes necessary, special
updated software is required ( delivered with the new board). Boards of old style and
new style are similar and exchangeable (for more details, see section 10.2.).
Exchange: Switch off line power and change out the board. The new style board has
additional 4 open collector drivers. See section 10.2.2.4.for more details.
7.5. Spare parts packages
A number of different spare parts packs are available depending on the operational
period. Consideration should also be given to the country of use and conditions at the
site where the analyzer will be used. Following careful evaluation, the spare parts
package can be adapted as necessary. The packages shown below contain a
sufficient range of parts, based on normal operating experience.
The one-year package contains consumables and spare parts for 1 year of normal
operation. Process criticality, installation location and country of use should be taken
into consideration to determinate what spare parts should always be available locally.
Spare parts list: One Year operation
1 (1) Blower power supply 2 (2) Fuse to power supply
3 (10) Quartz burners jets 4 (2 m) EMV door gasket
5 (2) Paper filters 6 (2 m) Rubber tube NBR 4x2 mm
7 (1) Diaphragm gas pressure regulator 8 (1) Ignition electrode
The 2-3 years operation pack contains the same parts as a 1 years operation pack
but with an extended supply of consumables, as well as electrical and electronic
components which, based on experience, can fail first in corrosive environments or
under other severe operating conditions.
Spare parts list for 2-3 years operation
1 (1) Blower power supply 2 (2) Fuse to power supply
3 (10) Quartz burner jets 4 (2 m) EMV door gasket
5 (2) Paper filters 6 (2 m) Rubber tube NBR 4x2 mm
7 (1) Diaphragm gas pressure regulator 8 (1) Heat exchanger
9 (1) Gasket for heat exchanger 10 (1) Solenoid valve
11 (1) Thermopile 1x24 TE 12 (1) Ignition electrode
13 (1) Ignition transformer 14 (1) Sensor differential pressure gas
15 (1) Sensor differential pressure air 16 (1) Sensor prepressure gas
This spare parts pack serves as a source of local stock. If components in the unit fail,
that are not contained in the spare parts pack, they can be ordered from the factory
by stating the 5-figure serial number list on the data plate. Without this number, the
spare part type or version cannot be accurately determined. All the serial numbers
are registered in a database together with all calibration data and settings that where
established before delivery from the factory.
