EK280
− The two mains voltage time windows are set under:
- Parameters > Interfaces> Connections > Connection 3
- Parameters > Interfaces> Connections > Connection 4
If you do not need a time window, you can deactivate it by setting the time window start and end to the same
value.
− Press the "Transfer changes to
7.1.4.2 Checking GSM field strength
Before starting a data transfer via the modem, you must ensure that there is adequate reception field
strength.
− For an EK280 with mains power supply, reconnect the mains voltage now.
a) Opening the test time window on the device
i
The test time window only needs to be open if none of the time windows 1 to 4 are open.
− Move the cursor to the "Serv." tab in the EK280's display, then to
Interfaces> internal modem > CWTst
− Press the ENTER key in order to enter the length of the test time window in minutes ⇒ "0" flashes.
− Move the cursor with the arrow keys  or  to the digits and change these with the arrow keys  or
 to 10, for example.
After the desired digits have been changed, press the ENTER key in order to confirm the input. It is
−
possible to abort the entry by pressing the ESC key.
Only enable the test time window for battery operation for as long as is required. Each time the
i
test time window is open, this reduces the life of the EK280 battery.
The editable time window is not directly reflected in the forecast of the remaining battery life of
the batteries" BatR" of the EK280. Therefore the forecast battery life is not changed if the time
window is changed. Past time windows and data transfers are however used in the remaining
battery capacity "BatRK" and remaining service life forecast calculation.
b) Display GSM field strength
− Check whether corresponding bars indicating the reception level for the internal modem ("i") appear
on the main EK280 display.
− Move the cursor to the "Serv." tab in the EK280's display, then to
Interfaces > internal modem > GSM and GPRS > GSM.L
− The percentage field strength is now displayed under GSM.L.
− In order to update the level display, move the cursor to GSM.L, please press the
EK280 and then wait approx. 30 seconds. This makes it possible to determine the best installation
position for an external GSM antenna.
