Operating the Device
102
6.8.3.3 Power on Modem
This option will turn the modem on for 5 minutes (i.e. 300 seconds; the remaining time in
seconds to turning off the modem 1 shows in the top right corner of the display). This
command is useful, for example, to test the communication when setting up the device
(basically simulates the function of the internal parameter "Timer - Service Window"
described in the TELVES program parameterization).
6.8.3.4 Call to Dispatch
If the device is configured to call the dispatch centre, this command can verify that the
device call to the master system is correct (applies to both dial-up connection and GPRS
mode). This option basically simulates the function of the internal parameter "Timer - Call
Window". On the first row of the display, the modem states (switching on, initializing,
connections ...) are displayed sequentially through which the modem goes through when
the connection is terminated. When the connection is established, the device sends the
calling data frame to the master station, which must accept it when the settings are correct.
After that, the modem terminates the connection and is turned off.
6.8.3.5 Modem Battery
It displays the battery charge status of the modem in % and the current battery voltage. If
the battery is disconnected, the message "Communication Error"/"Comm.error" appears.
6.8.4 Frozen Values
This option freezes the actual values. Use this option if the measured data have to be copied
manually.
