13) DIGITAL SELECTOR ET-DSEL – PURPOSE AND CONNECTIONS
The digital selector ET-DSEL is an essential tool for the installer, to configure the
automatic door operation and perform the
set-up and function/parameter setting operations, to carry out the system diagnostics
and to access the event memory containing information about the automation and
its operation.
Access to the programming menu is protected by a technical security password, to

automation.
The digital selector ET-DSEL can also be used by the final user, but only to select
the operating mode of the automatic door; the user can also select the preferred
language and set up a user password to prevent the use of the digital selector by
unauthorized persons.
