Alarm output port
The “Alarm output port” can be used to “switch on” or “trigger” an
external device in case of an alarm situation
by means of an “
” (ML-x15/WDL-x14) or the “module power switch”
(ML-2013).
When in “Continuous state” the output will be activated
as long as an alarm situation exists. If you only want to trigger an
external device when a new alarm situation occurs you can specify
a “One-time pulse” with a certain pulse width in seconds. If you want
to re-trigger the external device at every sample interval, while in
alarm, choose “Repeating pulse”.
Note: When a logger is awake (e.g. during USB connection) and frequently sampling its sensors and
inputs then
“repeating pulse” may look similar to “continuous state”, due to overlapping pulses.
Deployment Date and Time
Here you enter the specific Date & Time On which you like the measurements to start for the first time.
This feature allows you to configure your data logger (in a nice and warm environment) before you install
it in the field. It prevents the device to measure and send fake data, due to the dislocation of the unit. If
this feature is used, the unit will sleep until the deployment date & time.
Daily operating time slot
This setting allows you to disable the data logger from operation, outside this interval. This makes sense
when measurements are correlating with working hours or in other specific situations. E.g. a data logger
won’t alarm, or log data, when the temperature of the boiler is too low, while no-one makes use of that.
The logger will alarm you, when this happens during a working day.
Time zone
Time offset to meet local time zones (half’s and quarters are allowed).
Summer time
This setting allows the data logger to adjust its internal clock to summer time conventions. Worldwide,
there are multiple conventions, and therefore the user can adjust it to manually. Also a couple of
preprogrammed summertime conventions are selectable (Europe / USA). OR the user can disable the
feature (default)
When the user enables the summertime feature, as a consequence, there will be an anomaly in
the data. At the beginning and at the end of the summertime-period.
