other data.

6 Programming and con guration
There are two programming levels:
1. Cycles programming (for operator/user) means entering time/setpoint
values for each step of cycle.
2. Con guration (for manufacturer/installer of plant), to enter main par me-
ters (sensor type, output type, auxiliary output intervention type ext.).
6.1 Programming (or modifying) cycle data
With or without starting setpoint and timed auxiliary outputs.
The above speci cations underline the possibility given to the installer
(plant’s manufacturer) to choose the sequence of operations required for the
programming of a  ring cycle.
This paragraph includes all available options. In case that the installer de-
cides to choose a simpli ed programming with less options, it is highly re-
commended to prepare additional instructions specifying only the choosen
sequence.
