7.4.4 Display Master/Slave system
To display a summary of the Master/Slave 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 Master/
Slave network unit status indications:
Symbol Unit status in the Master/Slave system
Indicates the current unit being displayed (PGD or web server)
The unit is: online
The unit is: offline
Unit not configured and not included in the Master/Slave
system
The units in the Master/Slave 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.
7.4.5 Software backup function in the Master/Slave
system
Master/Slave mode can also be used to manage the software backup
function; if one or more units in the Master/Slave system is affected by
a malfunction, the system automatically restores humidity production
by activating the backup units. The lost production in relation to the
humidification 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 Master/Slave system; if
using probes on the other hand, each unit must be fitted with a probe.
Only in this way can complete operation be guaranteed in the event of
malfunctions.
Note: if a unit goes offline 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.
