Standard Mode - Burkert 8020 Notice D'utilisation

FLOW SENSOR TYPE 8020
4 COMMISSIONING

4.3.2 Standard Mode

After the operating voltage has been switched on, all segments on the control unit light up
for approx. 2 secs. (display test). Then the current flow rate is displayed and the
corresponding 4...20 mA standard output signal is provided.
The standard signal range is limited by the flow rate transmitter scaling. The flow rate value
assigned to respectively 4 and 20 mA must be indicated.
If one of the upper or lower limits is passed, the display will remain at its lowest or highest
value and the output will be of 4 or 20 mA accordingly to the passed threshold.
When the flow rate transmitter is in standard mode, the current flow rate is displayed.
4.3.3 Programming Mode (see Fig. 4.4 )
Pressing the ">" key for approx. 2 secs will switch the device into programming mode
(warning : if no sensor (8020) is connected, the ">" key must be pressed for at least 8 secs).
The K-factor of the fitting, the lower and upper range values can now be set. Each item
is set individually in the sequence described in the following chapter. The value flashes
when it can be set. The "E" button is used to change the value.
Use the ">" key to move to the next item.
If the last item has been reached, and the ">" key has been pressed all adjustable values
will be stored and the device will return to standard mode.
Note : When the system is in programming mode, the 8023 flow rate transmitter will
continue to operate with the previously set values, i.e. it continues to output the current
standard signal during programming mode. The reset values are only taken into
consideration when the programming mode has been quit.
Fitting Factor-K Multiplier (see Fig. 4.2)
Since the display only permits values to be set between 0 and 199.9, a multiplier is
introduced. If this is set to x10. this means that the adjustable value is multiplied internally
by 10. If, for example, the fitting factor has been set at 10.45, the value set is actually 104.5.
The multiplier is not displayed in standard mode.
x1 x10
x1 x10
Maximum K-Factor value: 1999.
