Display Averaging Filter
-
The Display Averaging Filter filters the data shown on the
display. It affects all elements of the display. The filter has 1 - 10
settings; 1 is the lightest filter, and 10 represents the heaviest
filter. It also has an Off setting.
Zero Lockdown
Zero Lockdown will drive the displayed flow and velocity, as
well as the associated outputs, to zero when the velocity is
below the set point. As very low air velocities tend to be noisy
and unstable, it may be best for control purposes to raise the
zero lockdown velocity to an appropriate threshold in which the
velocity is steady and reliable.
Alarm/Alarm Configuration
The Alarm/Alert Configuration menu provides access to select
and configure the transmitter alarm and alerts. Alarm type
can be either flow or temperature with Upper and Lower
limits. The transmitter alarm controls an on-board relay (see
the wiring diagram for Normally Open and Normally Closed
configurations). Alerts are messages possibly indicating issues
with sensors or the transmitter
Alarm/Alarm Operation:
If the process value (Type) exceeds
the Upper or Lower Limit, the relay will change state from the
default of NO or NC and the Type will change to red. When
the process value recovers to be within the Upper and Lower
Limits, the relay will return to the default state and the Type
will return to black. Limit Units are shown in parentheses.
These units are controlled by the System of Units and the
Units of Measure. If the units are US and the flow is CFH,
CFH will be the units used in Limits.
Alert Operation:
Enable Reg. Alerts will turn ON / OFF
Enable Global Alerts will turn ON / OFF
