9. WIRELESS PROBES, INSTALLATION AND CONFIGURATION
9.1 Type of installation and wireless probe
electrical connections
Wireless probes are available for systems where standard wired probes
cannot be used, for example modifications to existing installations. An
Access Point (CAREL P/N: WS01AB2M20) is used to connect up to four
wireless probes. Recommended Carel wireless probes are the room
(WS01G01M00) or industrial versions (WS01F01M00), both of which
measure humidity and temperature. The type of installation is shown in
the figure below (referring to four wireless room probes):

To connect the humidifier to the access point, use the Fieldbus
connection on terminal M3 (M3.1: Tx/Rx-, M3.2: Tx/Rx+, M3.3: GND):

Note:
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 defined probe groups.
The table below shows the part numbers and descriptions of the Carel

9.2 Wireless probe installation
The main steps for installing the wireless devices are:
•
power on the access point (12/24 Vac/dc ±10%m, 100mA) 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:
DIP:
1 2 3 4 + + G - -
Rx- Rx+ GND
L1L2L3
T1
DIP 1-2-3 selezione indirizzo di rete
DIP 4 selezione baud di rete
Dipswitch Access
Point
Serial port baud rate
(Bit/S) N82
1 2 3 4
2 19200
OFF ON OFF ON
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:
Address Dipswitch
1 2 3 4 5 6 7 8
Probe 1 16 0 0 0 0 1 0 0 0
Probe 2 17 1 0 0 0 1 0 0 0
Probe 3 18 0 1 0 0 1 0 0 0
Probe 4 19 1 1 0 0 1 0 0 0
Tab. 9.b
Remember to verify the quality of the wireless signal between the Access
Point and each wireless probe.
For a complete description of the installation procedure, see the Carel
manual on the corresponding probes and access point.
To configure the probes refer to screens: Dc13, Dc14, Dc15, Dc16 and
Dc17.
In particular, screen Dc03 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 respectively.
