1.6 Permitted device variants

The permitted device variants for functional safety are defined by the signal converter variant
(for details refer to Signal converter on page 8), the flow sensor variant (for details refer to Flow
sensor on page 8) and the device versions defined by the electronic revision (for details refer to
Revision history on page 4). Unless otherwise specified, all subsequent versions can also be
used for safety functions.

1.6.1 Signal converter

The signal converter variant is identified by the CG number shown on the device nameplate.
The next figure describes the format of the CG number.

Details of the CG number decoding are provided in the handbook [1].

1.6.2 Flow sensor

The model and its options are identified by the V-type code on the device nameplate.
The type code is a series of alphanumeric characters (0...9 and A...Z).
Refer to the next table to find which positions in the V-type code are related to functional safety.
The positions are marked by the letter "x".
