6.5 Power options
In the DTM (see chapter "
Parameter adjustment with PACTware"
)
you can select under the menu item "
Energy options
" between the
modes "
Continuous operation
" and "
Power saving mode
".
In continuous (non-stop) operation PLICSMOBILE and the sensor
always remain switched on. Only in this mode can the instrument be
used for level monitoring and send an e-mail when a certain level is
reached or when an error occurs (measured value/status-controlled
transmission). In continuous operation PLICSMOBILE allows remote
parameter adjustment via the service department. Configuration
changes on PLICSMOBILE as well as the sensor can thus be carried
out remotely from any PC with PACTware via GPRS.
In this mode, the integrated GSM modem as well as the sensor
connected to PLICSMOBILE are switched on automatically when
the time-controlled transmission of a message is pending. After the
measured value is recorded, the log-in into the GSM network is car-
ried out and the measured value is transmitted. The instrument then
returns to power saving mode. The time for this process depends on
the network quality and is generally approx. 70 seconds.
