ISO4406 codes are encoded as:
𝑚𝐴
= 6 +
𝐼𝑆𝑂
/ 2
Or
𝐼𝑆𝑂
= 2 × (
𝑚𝐴
−
6)
So 6mA = ISO 0, 20mA = ISO28
AS4059E2
Parameters are output in the sequence:
<SYNC> <BASIC> <A> <B> <C> <D> <E> <F> <RH> <TEMP> <...>
AS4059E2 contamination codes are encoded as:
𝑚𝐴
= 6 + ((
𝑐𝑜𝑑𝑒
+ 2) / 2)
Or
𝑐𝑜𝑑𝑒
= 2 × (
𝑚𝐴
−
6
) −
2 = 2 ×
𝑚𝐴
–
14
So that 6mA = -2 = 000, 6.5mA = -1 = 00, 7.0mA = 0, 7.5mA = 1, 13mA = 12 =max valid reading, 20 mA = over range
6.4.3.3 Time Multiplexed Scheme 2
This outputs the parameters as currents, using values designed for viewing directly on a programmable process
meter. There is no "sync" value but the final parameter stays on for 2 seconds instead of 1. To avoid confusion the
RH channel does not output temperature (just static RH value). The other channel outputs just the overall
contamination code value except for ISO4406 where it cycles between 3 ISO codes.
6.5 Disposal
−
All CMS products are sent in a cardboard box with foam inside and these should be recycled accordingly.
−
Fluids used with the CMS should be fully drained and disposed of according to EU waste framework directive
and ISO44001 Environmental Management.
