Diagnostic displays of DeltaFlow-Monitoring

DeltaFlow-Monitoring (see Chapter 3.5.2 on p. 14) is signaled differently in
both of its applications.
DeltaFlow-Monitoring in the Teach-Mode is signaled as follows:
Depending on Teach-Function, synchronous yellow blinking of the entire
LED-band or of a single LED indicates a high temperature gradient (significant
change of the flow rate).
Synchronous green blinking of the entire LED-band or of a single LED indicates
a sufficiently small temperature gradient (insignificant change of the flow rate).
The Teach-Mode is continued.
IMPORTANT INFORMATION
Specification of the DeltaFlow-Display
The exact number and positions of the blinking LEDs is provided in Chapter 7.1
on p. 26 under the respective Teach-Function.
DeltaFlow-Monitoring during the heating phase after the start-up (see Chap-
ter 3.5.3 on p. 15) of the sensor is signaled as follows:
Synchronous yellow blinking of the LED-band and the LED "Flow" in a one-
second interval indicates heating of the sensor.
When the sensor is heated, the device automatically switches to the display
mode of the flow rate. This takes about 10 s.
The following table shows the general LED signals of DeltaFlow-Monitoring.
