- setting of transmitting power;
- setting of info-messages broadcasting period;
- correction of statuses of pulse counters - relatively (
”
add NN”) or absolutely (
”
set NN”) ,
Receiving of
”
Request” type message take place always during the 500 ms long time window that starts immediately
after transmitting of regular
”
User Data” info-message. During this interval the WB169-SI2 module opens its
receiver so as to be able to receive possible
”
Request” message. The module confirms receiving of
”
Request” by
sending of
”
Acknowledgment” type of message.
Management of
”
Request” type of messages must be implemented into the central application software or into the
superior
”
Master” device. The messages are coded by M-Bus standard principles with short Wireless M-BUS header
with special indication of
”
Request” type messages (C-byte =”53”, CI-byte = ”5A”). The message contains one
data block (with appropriate DIFE/VIFE code and required value) for each parameter, that should be remotely
changed. More detailed description of
”
Request” type of message can be provided by producer of the module on
request.

Hardware features and power supplying
The module is enclosed in transparent humidity-proof plastic casing and can be used in interiors as well as in
exteriors. The casing is designed for mounting on the wall or other construction element (beam, pipe...). Module
can be treated with an additional sealing by high-adhesion silicon filling, that can ensure proof against inundation
by water (IP68 grade). If this treatment is required from the manufacturer, it must be ordered separately.
The module can be controlled and configured either by configuration cable, or wirelessly - by infra-red remote
control with using of optical converter. The module is equipped with the circular crater-shaped pit, that supports
magnetic fixing of optical converter with holding on magnet in right position.
The module is power supplied by internal battery with 13 Ah or 5.8 Ah capacity (see ordering options). If using
of 13 Ah battery, the module lifetime for 60 minutes broadcasting period is more than 8 years. If using of 5.8
Ah battery, the lifetime is up to 8 years for 120 minutes broadcasting period. Battery lifetime can be negatively
influenced by shorter broadcasting period or by storing and operation in sites with the temperatures exceeding the
recommended range for module storage and operation. Operation in bi-directional mode (N2) with using of back
channel decreases the battery lifetime by 5 %. External appearance of the WB169-SI2 module is shown in the

Variants and ordering codes
The WB169-SI2 module is delivered in four variants with different capacity of internal battery and with different
degree of protection. There are four ordering codes for delivery of required hardware configuration of the module:
-
WB169-SI2-B13
- ordering code for variant with
13 Ah battery
and
IP65
degree of protection
-
WB169-SI2-B13/IP68
- ordering code for variant with
13 Ah battery
and
IP68
degree of protection
-
WB169-SI2-B5
- ordering code for variant with
5.8 Ah battery
and
IP65
degree of protection;
-
WB169-SI2-B5/IP68
- ordering code for variant with
5.8 Ah battery
and
IP68
degree of protection.
Together with the WB169-SI2 module also some time-tested sensors for industrial use can be ordered directly from
module’s producer (e.g. magnetic position sensor, security loop, flood detector...). Actual list of offered sensors is
available at producer’s e-shop:
