For the transfer of analogue signal values to setpoints, only the transfer ramp is now
defined. For this purpose, the minimum and maximum support points of the character-
istic curve are specified and the respective setpoints are amended (MIN signal/value as-
signment and MAX signal/value assignment).
Min signal/value assignment
Analogue input (AI2)
Signal value
Corresponding value
Set minimum point
of setpoint pump curve
of delivery head
for Δp-v.
Fig. 80: Minimum signal/value assignment
Max signal/value assignment
Analogue input (AI2)
Signal value
Corresponding value
Set maximum point
of setpoint pump curve
of delivery head
for Δp-v.
Fig. 81: Max. signal/value assignment
When all signal/value assignments have been performed, the setting of the analogue
setpoint source is completed.
An editor for adjusting the substitute setpoint in the event of a cable break or wrong
configuration of the analogue input will open.
Set input for external setpoint
Select setpoint source
Current source: Analogue input 2
Set setpoint source
Setpoint sensor: 4 – 20 mA
If a
cable break at the
external setpoint source
is detected, this substitute value is
used
as the setpoint.
