Figure 8-54 Setting the setpoint type
Analog input 4 is the dedicated hardware input for analog setpoint
signals. Therefore, this assignment cannot be changed.
Parameters:
Internal setpoint:
z
Define the internal setpoint for the selected unit.
External setpoint:
z
Enter the name. This parameter is not required; it is for internal use only.
z
Select the range of measurement range for the external setpoint: 0/4-20mA or
0-5/10V.
z
Set the setpoint input linearization. Under normal conditions, enter 2 for the
number of breakpoints. Set the starting setpoint start (= 0) to 0/4-20mA and
the stopping setpoint to 20mA.
Offset:
z
Enter the offset to be added to the external setpoint. Negative values are
acceptable.
Setting a 4-20 mA range for the external setpoint initiates monitoring for cable
breaks. The unit switches over to an internal setpoint when a cable break is detected
(default setting = 100 l/s).
Relays
Use this menu to modify the logic functions for both output relays.
