7.4 Device status
The table below indicates the symbols which may be displayed in the device status.
Device status information is available and visible at any time of device operation in stand-
alone mode.
Symbol Description
, ,
Battery charge level (approx. 100 %, 66 %, 33 %)
Critical battery voltage level. PROFIBUS Tester 5 is going to
shut down automatically in a couple of minutes. Connect
PROFIBUS-Tester 5 to the AC adapter.
AC adapter connected and battery is charging.
Battery completely charged - without AC adapter connected.
Battery completely charged - with AC adapter connected.
Battery not found or defective. The device runs with external
power supply.
There is activity on the bus. If the LED is green, but no baud
rate is detected (e.g. in Bus Status function), the activity on the
bus results from disturbances and not from regular frames.
No bus activity, open circuit voltage within correct range
between 0.8 V and 1.4 V. The bus termination is correct, but no
frames are transmitted on the bus. To run a test, you have to
either switch on the PROFIBUS master or activate the master
simulator.
No bus activity, open circuit voltage below 0.8 V or above 1.4 V.
If an open circuit voltage greater than 0 V is displayed in Bus
Status function, the bus has not been properly terminated. An
open circuit voltage of about 0.5 V to 0.6 V is a sign that no
power is supplied to one of the two bus terminations.
Master simulator is active. You can start the master simulator
from the "Extras > Master simulator" menu.
