Software Update
Loading a software package (.levi-file)
via the USB drive allows the customer to
perform a software update on the controller.
Select
REFRESH
to search the USB drive for
a file, then select
Update
. Only one .levi file
should be on the USB drive. The flow meter
firmware can also be updated here.
Software/ Firmware Update Wizard
About System
This section contains information about the
controller and its connected peripherals,
like serial numbers, component names and
software/firmware versions.
Sensors Settings
Note Only single-use pump heads should
be used with this controller. The
controller does not support firmware
for the multi-use pump versions.
Flowmeters
Flowmeter settings contain all configuration
parameters for each flowmeter. If a clamp-
on sensor (LFSC-i06X) is connected, the
Tubing & System Temp
setting will show
the calibration sets for this sensor. The user
can choose from a list of tubing types and
operating temperatures by selecting the box
displaying the current selection. When using
the Cellicon
TM
filter, select Advantaflex, 37
0
C.
The low cutoff setting can be specified by
the user. Every flow value below this cutoff is
shown as 0 mlpm.
When a less noisy flow signal is required this
signal can be smoothed by increasing the
damping time. Be aware by changing this
damping time the flow control performance
can be influenced negatively.
The flow error ignore time defines how long a
flow measurement error needs to be present
until any action is taken by the system. In
flow setpoint mode the defined pump behavior
is triggered (Settings
Controls
Flow
Control
Pump Behavior on Flow Error). In
speed setpoint mode, when the ignore time
has expired the flow value is set to 0 mL/min,
the flowmeter shows an error.
The resolution of the flow signal can be
improved by decreasing the full scale of the
flowmeter. The resolution of the flow signal is
always 1/10,000 of the full scale. Decreasing
the full scale below 1000 mlpm affects the
max flow setpoint.
Calibrate flowmeters every one to two years.
Pressure Sensors
An offset can be defined for each pressure
sensor. This value is automatically adjusted
when the zero adjustment is performed.
A quieter pressure signal can be achieved by
increasing the damping time.
The displayed pressure unit can be either psi
or mbar.
Alerts Settings
This section allows a user to configure how
different types of alerts are communicated.
If alerts are selected as
Show
, a message
will appear in the alert bar area of the main
screen. If alerts are selected as
audible and
full-screen
, a full screen alarm appears with
an audible beep sound. Each alert will be
added to the alert log, found by selecting
Alerts
from the main screen.
If the controller is in standby mode when
the alert occurs, the alert will appear on
the screensaver. It will also be added to the
backlog of alerts on the main screen.
Audible alarms can be enabled or disabled, except:
• When pump errors are configured as
visible (
Show pump errors
), every
pump error that occurs when the pump
is enabled results in a full screen alert
together with an audible beep sound.
• When flowmeter errors are configured as
visible (
Show Flowmeter errors
) and the
flowmeter gets disconnected while in flow
control mode results in a full screen alert
together with an audible beep sound.
General Alerts
Application specific alerts, data logging
aborted alerts, and out-of-setpoint tolerance
alerts are alert type 2 and can be found on
