Flowmeter Alerts
When alerts for Flowmeter 1 are activated,
the system will take the selected pump
behavior on flow error (Settings
Controls
Flow Control
Pump Behavior on Flow
Error). Flow alerts can be found in the
.
Flow alarms can be configured to provide an
alert when the actual value deviates outside
a specified range.

Critical alarms (type 1 alert) are shown in
red color, and warning alarms (type 2 alert)
are shown in yellow color. Neither critical nor
warning alarms will shut down the pump.
The
Show flow alarms
selection activates all
the flow alarms for that sensor. The
Critical
flow alarms are audible and full screen
selection enables only the critical alarms to
be audible and full-screen.
Pressure and TMP Alerts
Pressure and TMP alarms can be configured
to provide an alert when the actual value
deviates outside a specified range. These
alarm levels define when a pressure or TMP
alarm notification goes active.

Controls Settings
Flow Control
The
Flow Control Settings
define the
parameters and take effect when the system
is running in flow setpoint mode. Flow
setpoint mode is activated by switching the
toggle on the main screen to show
Flow
Setpoint
highlighted by a white box.
P and I parameters can be adapted to
optimize the flow control behavior.
The minimum and maximum speed define
the range of pump RPM that the system will
allow. These settings only take effect when
running in flow setpoint mode. The setpoint
increment step defines which amount the
flow setpoint is increased/decreased when
selecting
+
or
-
on the main screen.
The setpoint tolerance parameter defines the
band around the setpoint which the actual
flow must reach.
Out of tolerance
alert will be activated when
the actual flow does not reach the setpoint
tolerance band within the time defined in
out of tolerance alert delay
. Activate the
alert to be notified when an
out of tolerance
situation is present (Settings
Alerts
General
Out-of-Setpoint Tolerance Alerts).
A flowmeter error can be defined when the
number of seconds exceeds the setpoint in
Flow Error Ignore Time
(Settings->Sensors-
>Flowmeter). The controller takes one of the
following actions, which can be defined under
Pump Behavior on Flow Error
:
• Hold Current Speed: The pump
continuously holds the same speed.
• Choose Custom Speed: The pump
defaults to the defined speed.
• Stop Pump: The pump stops.
