Minimum duration of abnormal consumption (
”
Burst Check Time”) can be set up in range 1 - 1090 minutes with
precision of ten minutes (rounded to tens of minutes, e.g. 10, 20, 30...). If the command is entered with any other
value (e.g. 36 minutes) the system will store rounded value anyway (in this case 40 minutes). General principle
is that setting of Burst Check Time parameter to longer values means that the detection is more reliable, with
lower probability to produce false alarm due to random changes in normal operation (e.g. during filling a tank with
water), but in the same time it will prolong the response time between the breakdown and sending of alarm.
Setting of
”
Burst” alarm function parameters appears in the List of configuration parameters - in the section of the
particular port:
MBUS value[0] DIB : 04 00, VIB : 13 00 ,multiplier 1, divider 1
Broken pipe min. 15 pulse/10 min. during 40 minutes
Structure of
”
Burst” alarm message is described in the paragraph
”
Alarm message”.

Setting of sensor inputs
Any two-state sensors of
”
on/off” (0/1) type with contact, relay, or electronic binary output (e.g. door contacts,
flood detectors, fire detectors, electronic seals...etc.) can be connected to any WB169-SI2 module port. If the port
is not preset to
”
alarm mode”, the module only stores number of 0/1 transitions of the sensor into the counter and
