9.4.4 Display Main/Secondary system
To display a summary of the Main/Secondary system, go to screen Dd08.
The menu displays all the units (01, 02, …), the status of each unit and
current production as a percentage. The following table lists the Main/
Secondary network unit status indications:
Symbol Unit status in the Main/Secondary system
Indicates the current unit being displayed (PGD or web server)
The unit is: online
The unit is: offl ine
Unit not confi gured and not included in the Main/Secondary
system
The units in the Main/Secondary system can also be selected one by one,
displaying maximum production, unit status, operating hours, current
production request and any alarms.
To enter this display, from screen Dd08, select the desired unit and press
, thus accessing screen Dd09. Scroll using the UP/DOWN buttons to
display the details of all the units.
9.4.5 Software backup function in the Main/
Secondary system
Main/Secondary mode can also be used to manage the software backup
function; if one or more units in the Main/Secondary system is aff ected
by a malfunction, the system automatically restores humidity production
by activating the backup units. The lost production in relation to the
humidifi cation request is thus compensated by increasing production on
the individual units (where possible) and/or starting any units in standby.
Even if not strictly necessary, to ensure the backup function, the external
control signal must be sent to all the units in the Main/Secondary system;
if using probes on the other hand, each unit must be fi tted with a probe.
Only in this way can complete operation be guaranteed in the event of
malfunctions.
Note: if a unit goes offl ine due to a malfunction or shutdown, it will
temporarily be excluded from the system, and when next restarted it may
take 15 seconds or more to automatically come online status again.
