Terminal Input = Differential Pressure and Block Output = Flow
The filter function of the analog Input block is activated by setting the parameter
Filter Time to a non-zero value. The filter characteristic is shown below.
Figure 37 Filter Characteristic.
Notes:
• For details of the parameter Alarm please refer to Appendix B Error, Warning
and Information Messages.
• If a warning is set the controller displays a message while continuing to operate
normally.
• The parameter Loop is used only on the ECA600. Alarms can be set to act on
either loop independently. The control block designated by the Loop parameter
for alarm will react according to the parameter ErrorBehavior in the Control
block. The other Control block (loop) will continue to function as normal.
