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
of Alerts.
Flow alarms can be configured to provide an
alert when the actual value deviates outside
a specified range.

Refer to Table of Alerts for more information.
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 flow alarms for that sensor. The
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
Table alarm notification goes active.

Controls Settings
Flow Control
The define the
Flow Control Settings
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
highlighted by a white box.
Setpoint
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.
alert will be activated when
Out of tolerance
the actual flow does not reach the setpoint
tolerance band within the time defined in
delay. Activate the
out of tolerance alert
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
(Settings->Sensors-
Flow Error Ignore Time
>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.
