Function group
CURRENT OUTPUT
This function group is not available when the setting “RS 485 / FREQUENCY” or “AUX. INPUT / FREQ.”
is shown in the function “SYSTEM CONFIG.” for the communication module RS 485 (see page 71).
FULL SCALE 1
Enter the desired full scale value for the flowrate at 20 mA. The max. possible
overload of the scaled full scale value depends on the setting in the function
“CURRENT SPAN” (see page 51).
Note!
• Scaling always applies to both directions of flow (bidirectional), but with the
unidirectional mode, no signal is shown for a negative flow.
• When programming according to NAMUR, the measuring range is reduced
from 12.5 m/s to 10.25 m/s.
• Dual range mode and flow direction can be given by both relays
(see page 60, 61).
