Fig. 9-5 Time of day totalising
If the transmitter is disconnected from mains at the time of totalising set, it is
not possible to create or to save a total for the respective day.
If the unit has been shut down temporarily within 24 hrs. the flow rate missed
during the inoperative period is not going to be considered for totalising. There
will be no averaging interpolated replacing the lost flow rate!
Error messages
This menu is to monitor any interruptions in the unit function. Errors are go-ing
to be saved and ordered by type of error, date and time.
Selecting the menu will always indicate the latest/last error message. Browse
through error messages using the keys >left< and >right<.
Pressing the >ENTER<-key will delete all error messages one by one.
The maximum number of stored error messages is limited to 10. The oldest of
11 error messages will be overwritten as soon as saved old error messages
are not going to be erased (circular memory function).
Following error messages are possible:
-
“Doppler-Sensor“ - at interruption of the sensor communication or with de-
fective KDA sensor
-
"external level “ – at interruption of communication to external level meas-
urement or if value falls below the limit of 3.5 mA
-
"external level short-circuit“ – in case of exceeding the input signal 20 mA
-
"temperature“ – in case of exceeding maximum or minimum permissible
temperature ranges by +/-10 °C (as from -30 or +60 °C) or if the temperature
sensor should be defect
-
“ext. set point“ – if external set point is not available
-
“control unit“ – in case of error of the control unit ("Valve OPEN", "Valve
CLOSED", "Valve TORQUE")
