7.8 List of configuration parameters
The following is a complete list of parameters managed by the application, each with a short code, the ModBus address
(Adr), brief description, default values and limits, measurement units (U), the menu in which they are accessed (M)
and the notes.
The menus are split into levels: U (User), I (Installer, protected by first-level password), M (Manufacturer, protected
by the second level password.
All the parameters in the User menu are freely modifiable and their modification is immediately applied. The Installer
parameters are usually loaded by the application only when the machine is in the Stand-by off (10), and can be
changed only in this state. The Manufacturer parameters are the most low-level and are usually loaded by the
application only at the start-up, can be modified only in the Stand-by off (10) and requires a reset to load the new
value.
The variable Parameters status (ParS) indicates that the modified parameters have been acquired but are not currently
in use. To finalize the acquisition, it is necessary to reset or disable the valve. If the variable is set to 0, it means that
the new parameters are already active.
The correct procedure for changing Installer and Manufacturer parameters is:
• disable the valve
• modify the parameters
• verify the Parameters status (ParS) value
• reset the board if requested by Parameters status (ParS)
