MANUALE D’USO – USER MANUAL
SINGLE HUMIDIFIER CONFIGURATION (default configuration)
The humidifier is set as "single" (MS=0) and works autonomously, following the setting
assigned in variable S9.
MASTER/SLAVE HUMIDIFIERS CONFIGURATION
In this configuration, the humidifiers (maximum 6 units) behave as if they were one machine,
producing steam according to common reference given by the Master unit.
The Master also manages the priority deconcentration or test discharges of the various
humidifiers (including its own), with FIFO (one deconcentration discharge at a time),
guaranteeing continuity in steam output.
Connections between master and slave:
The humidifier configured as master, communicates with the various slave humidifiers by
means of an RS-485 serial connection between the various 100-Master electronics.
Maximum connection length is not defined but depends on the quality of the cable and the
signal/disturbance ratio. It is indicatively fixed at 500 metres.
The connection cable can be non-shielded if the distance is of a few metres in an electrically
slightly "noisy" ambient. For distances between 15 and 100 metres, it is possible to use a
shielded and twisted cable without particular features, whereas for connections over 100m it is,
for example, advised to use BELDEN 8762 cable.
The communication line must be of chain type, avoiding star configurations.
The shield of the used cable must be ground connected on one side. Avoid housing the RS-485
serial connection in the same ducts (or tubes) of the power or power supply cables.
