Operating status LED
On
The LED is permanently on:
Green in normal operation, blue or red in case of diagnosis.
OFF
The LED is permanently off.
Noti
The LED only lights/flashes blue or red in case of diagnosis.
Diagnostic cases are:
•
Low or no signal quality. See also:

10.6.7 Simulation
With this function, process values are simulated and their signal path is checked.
Process values that lead to an error message or warning can be simulated (e.g. OL: process value
above the measuring range).
When the simulation is started, the values of the totaliser are frozen and the simulated totaliser is set
to 0. The simulated flow value then has an effect on the simulated totaliser. When the simulation is
ended, the initial totaliser values are restored.
During the simulation:
•
The simulation has no effect on the current process values. The outputs operate as previously set.
•
The original totaliser value remains saved without any changes even if there is a real flow.
•
No error messages of the current application are available. They are suppressed by the simulation.
The following values can be simulated:
•
process values for flow and temperature
•
process values outside the measuring range (cr.UL, UL, OL, cr.OL)
10.6.7.1 Parameter setting via unit keys: simulation
u
Select [EF] > [SIM].
u
Select [S.FLW] and set the flow value to be simulated.
u
Select [S.TMP] and set the temperature value to be simulated.
u
Select [S.Tim]and set the time of the simulation in minutes.
u
Select [S.On] and set the function:
•
[On]: The simulation starts. The values are simulated for the time set under [S.Tim]. Abort by
pressing any key.
