1.5 Three additional pulse inputs (optional; only in conjunction with M-Bus or radio)
With this option, additional instruments with pulse outputs can be read out via optical interface, M-Bus or radio.
General information about pulse inputs:
It is important to note that the acknowledged state of the art technology rules and the relevant legal restraints (international
and local; see "Relevant Norms / Standards / Literature Pulse Inputs") are to be observed.
The installation has to be performed by authorized, skilled persons.
If the regulations and the information in the installation and operating instruction manuals are not strictly followed, or if the
installation is shown to be faulty, any resulting expenses will be charged to the company responsible for the installation.
