The picture code identifies the exact build of the analyser. It is of the following form:
01100A
7 GEN 01 01 0 0 0 0 0 0
Analyser Type
Picture code issue number
Hazardous area certification
Analyser configuration code (Feature 1)
Options, etc. (Features 2 to 14)
1100 systems using the high temperature transducer (1132) have the analyser type 01100H,
not 01100A.
A set of picture codes is shown in Appendix 2. Choose the appropriate picture code by issue
number.
When ordering spare parts, the identification number and the serial number of the relevant unit
should be quoted.
Major sub-assemblies, e.g. printed circuit boards, have part numbers of the form 01100925B
(analogue amplifier board). A listing of the major sub-assemblies or commonly used parts is
given in Section 6.
Software is identified on the analyser identification label and on the display when the analyser
is first powered-up - see Section 3.3. It is also shown on the memory circuits. Note that the
microprocessor board (01100918C or 01100918D, or earlier versions) are only supplied as a
spare part complete with software. The ordering information for this is given in Section 6.
1.4 ANALYSER CONFIGURATIONS
The Servomex 1100 series oxygen analyser is available in several different configurations,
identified by Feature 1 of the picture code.
