gaSteam/access point connection:
To connect the humidifi er to the access point, use the Fieldbus connection on terminal M3 (M3.1: Tx/Rx-, M3.2: Tx/Rx+, M3.3:
GND):
Fig. 6.r
Notice:
the devices have a range of
around a hundred metres in a free space, i.e.
without any obstacles. In a closed space, the
range varies considerably depending on the
type of environment and the surrounding
objects (shelves, metal partition walls etc.).
If installing multiple wireless probes, the controller will calculate the weighted average between the various probe readings,
depending on the settings made by the user and the defi ned probe groups. Also see the paragraph “Wireless probes”. The con-
troller also displays (locally only) the battery and signal level for each probe (screens D05 to D08). The table below shows the part

ireless probe installation
The main steps for installing the wireless devices are:
• power up the access point (12/24 Vac/dc ±10%m, 100 mA) and complete the initialisation procedure, creating the network
and selecting the channel;
• after having opened the domain on the access point, complete the binding procedure so as to uniquely identify each probe.
The address to be used by the access point is set using the dipswitches on the device, and is the following:

This assigns the address 2 to the access point, with a baud rate (bit/sec) of 19200 (N82). The addresses of the four serial probes,
on the other hand, must be set as shown in the table below:

Remember to verify the quality of the wireless signal between the access
point and each wireless probe. For a complete description of the installa-
tion procedure, see the manual on the corresponding probes and access
point. To confi gure the probes, see screens: Ec03, Ec04, Ec05, Ec06 and
Ec07 described under “Wireless probes”. In particular, screen Ec03 is used
to enable the wireless probes connected to the access point, knowing that
addresses 16, 17, 18 and 19 are Probe 1, Probe 2, Probe 3 and Probe 4 re-
spectively.
