Fig. 55: 3ADR331191S0015_07AI91-AD
The replacement device 07AI91-AD from the AC31 adapter series replaces the existing device
07DC91 from the 90 series.
During the development of the replacement device, care was taken to keep the device configu-
ration identical to the configuration of the existing device. Thus, the existing documentation of
device 07AI91 remains valid and serves as a reference
(system description Advant Controller 31). The document structure of this document is based on
the document structure of the existing documentation.
This document adds the following points to the still valid existing documentation:
● Unavoidable device deviations, e.g. due to technical limitations.
● Expansion of documentation as a result of normative requirements.
● Additional contents not described in the existing documentation.
Further information on replacement device 07AI91-AD can be found in the operating and
assembly instructions of device 07AI91-AD: 3ADR020086M0401. Please note that for the
existing device 07AI91 no separate operating and assembly instructions are available.
