The design of the power entry module requires the line cord be disconnected before the line fuse is removed. Refer to
the Title Page section for fuse information.
3.1.3 Fluid Movement
Fluid movement in the system is achieved by the displacement actions of the pump. A piston moves forward and
reverse in the pump chamber moving fluid in and out of ports. The piston rotates to move a flat on the piston between
the two ports (Port A and Port B) to achieve the desired fluid movement through the system. The movement of the
piston is initiated by an Actuator Module driven by a motor. The Controller Module provides the control and power to
the Actuator Module's motor to achieve the desired fluid movement.

DIGISPENSE 3020 CONTROLLER MODULE Page 3-7
7 April, 2011 IVEK Corp. P03L011B
The movement of the piston is either forward (dispense) or reverse (load). A dispense is typically a settable volume of
fluid movement while a load is an attempt to prepare the chamber for the next dispense (dependent on mode of
operation). A dispense, depending on mode, allows for configurations based on rate, drawback, volume, etc. A load
can only be configured for rate.
Fluid movement is controllable from two different contexts: Production Mode and Fluidic Setup Mode. Production
Mode is intended for normal controlled fluidic movement operations and Fluidic Setup Modes are intended for
preparing the entire fluidic system for those controlled operations.
3.1.4 Dispense/Load Rate
The optimum value of the Dispense or Load Rate needs to balance decreasing cycle times with an increasing risk of
cavitations of the fluid reducing repeatability. Also, since motor torque decreases with increasing speeds, the
probability of stalling the motor in the Actuator Module increases, especially when the viscosity of the fluid is high.
Often, a larger diameter tubing is used between the supply reservoir and the pump so the chamber may be prepared
for the dispense more quickly. This often allows for the use of a much faster load rate to reduce the overall cycle time
of the operation.
Since a precisely controlled dispense is often the goal of the system, the fluidic system attached to the active port is
often carefully selected based on desired volume, fluidic characteristics, etc. This means the dispense rate is often
lower than the load rate to increase repeatability and reduce the probability of fluid cavitations.
Advantages Disadvantages
Decreased Rates Lower probability of stalls & fluid cavitations Longer cycle time
Increased Rates Shorter cycle time Higher probability of stalls & fluid cavitations
3.1.5 Direction
In some modes of operation (all Production Modes and Prime Mode), a direction selection of either forward or reverse
is available. This selection determines the direction of fluid movement through the Pump Module.
When the direction is forward, fluid moves into the inactive port (Intake) and out the active port (Discharge). When the
direction is reverse, fluid moves into the active port and out of the inactive port.
3.1.6 Active Port
The Pump Module contains two ports, Port A and Port B, for connection to the fluidic system. One port is always
designated as the active port and the active port is always the discharge port. It is only necessary to change the active
port if doing so eases the location of the tubing and other elements of the fluidic system.
Active port configuration is provided in the Setup C screen to allow initial fluidic system setup/location. Changing the
active port in effect reverses the fluidic movement direction, the controlled Dispense portion of the operation will now
occur at the opposite port location with the opposite rates. Following is a chart illustrating the nature of fluidic
movement based on active port selection and direction.

3.1.7 Pump 90 Degree Offset
Enabling the pump 90 degree offset allows the pump to be offset from the actuator by 90 degrees. This eliminates the
need to mechanically modify the actuator when changing port orientation.
The following table lists the Pump 90 Degree Offset and Active Port settings to change your output from what you
have to what you want. The first table is for the IVEK standard Actuator Module and the second table is for the
optional Actuator Modules. The diagrams at the bottom of the page show the output port locations for the four outlet
positions.
In Forward, Port A is always the input and Port B is the output. In Reverse, Port B is always the input and Port A is
the output.

3.1.8 Acceleration
The Acceleration setting determines how quickly the pump piston reaches the dispense/load rate from a stopped position. It
is also used to determine deceleration; how quickly the piston slows down when heading towards stop. Increasing the
acceleration may help increase the shearing of certain fluids from the tip improving repeatability. However, with higher
accelerations, high viscosity fluids may be more susceptible to causing the Actuator Module motor to stall.
Advantages Disadvantages
Decreased Acceleration Lower probability of stalls Less shear at tip
Lower probability of fluid cavitations Slightly longer cycle time
Increased Acceleration More shear at tip Higher probability of stalls
Slightly shorter cycle time Higher probability of fluid cavitations
3.1.9 Drawback
Drawback is provided in some operating modes (Dispense, Dispense MCV, Meter) to allow the fluid to move in the
opposite direction after a dispense to better separate the fluid at the tip. Often, high viscosity or “stringy” fluids are
susceptible to poor separation at the end of a dispense. Drawback provides a snapping motion in the fluid to attempt
to shear it off at the tip. There are three parameters available for configuration of Drawback: Drawback Volume,
Drawback Rate, and Drawback Dwell.
The Drawback Volume determines the amount of fluid to move backwards after a dispense. Typically, this is
configured for a small fraction of the dispense volume.
The Drawback Rate determines the rate of fluid movement during the backwards drawback.
The Drawback Dwell determines the amount of time the fluid movement pauses between the end of the cycle and the
beginning of the next cycle. Typically, this is left at the default value, but may be increased if it benefits the application.
3.1.10 Torque
The torque setting determines the peak current available to the motor. Increasing the torque decreases the
probability of stalling with high viscosity fluids. Decreasing the torque increases efficiency by decreasing steady state
heat loss in the motor when using low viscosity fluids.
Advantages
Disadvantages
Decreased Torque Reduced heat loss in the motor Higher probability of stalls
Increased Torque Lower probability of stalls Increased heat loss in the motor
3.2 STANDARD OPERATION
This Standard Operation section provides the information and instructions for the most common operation of the
system. Most of the screens and the less common information have been removed. If you are an advanced user or
need additional information please refer to Section 3.3 - Advanced Operation.
The Controller Module provides the controls for producing fluid flow via a positive displacement pumping mechanism.
The systems utilize solid-state electronics, stepping motor drives, and precision machined ceramic pump heads.
These components combine to provide exceptional accuracy and precision, high reliability, and low maintenance.
Volume commands for the Controller Module use microliters. Rate commands are in microliters per second. Pumping
is started using the Start push-button based on the screen being viewed. Push the Stop push-button to
stop the operation before the respective volume setting is reached.

DIGISPENSE 3020 CONTROLLER MODULE Page 3-10

3.2.1 Dispense Mode
Dispense Mode is the typical operating mode to use when dispensing fixed amounts of fluids. The amount of fluid to
dispense is configured by the Dispense Volume parameter. The range of the Dispense Volume is dependent on the
pump size and Actuator Module, but is normally a minimum of 0.01% of the pump chamber volume up to a maximum
of the full chamber volume. The repeatability of the dispense volume is dependent on many factors including: tubing
setup, selected tip, fluid characteristics, Actuator Module and pump characteristics, and fluidic movement profile.
Parameters such as Dispense Rate, Drawback, Drawback Rate, Drawback Dwell, and Acceleration, provide
configuration of the fluidic movement profile to provide the flexibility to meet the needs of various applications.
If the Dispense Volume setting is less than a half chamber, then multiple dispenses may be initiated before requiring
a reload. A reload will be required as soon as the volume remaining in the pump chamber is less than the amount
required for the next dispense or the volume dispensed has reached the Load Threshold.
3.2.2 Meter Mode
Meter Mode allows for variable fluid movement. The beginning and ending of the fluid movement may be initiated by
either the front panel start-stop buttons, RS232 commands or Logic I/O signals. However, the most precise control of
the start and stop of metering is via the Logic I/O signals.
Once initiated, fluid will Meter until stopped. If Drawback is enabled, it will be performed upon the stopping of the
Dispense.
If the Metering is not stopped, and the end of the chamber is reached, the operation will terminate and drawback will
occur if enabled. This means that a metered dispense may only occur up to volumes of a pump chamber volume
minus the drawback volume.
If the Metering is stopped before the end of the chamber is reached, another operation may be initiated, as long as
the volume displaced has not reached the Load Threshold.
3.2.3 Prime Mode
Prime Mode is the most typically used Fluidic Setup Mode and is used to prime the fluidic tubing and components
from the reservoir through to the tip before Production Mode operation. Having Prime as a separate mode from
production permits selection of optimum values for priming, which may be different than optimum values for
production. It is also often used in the Reverse Direction to remove the fluid from the fluidic system after Production
Mode operations are completed.
The amount of fluid moved is configured by the Prime Volume parameter. The range of the Prime Volume is
dependent on the pump size and Actuator Module, but is typically 0.01% to 1000 times the pump chamber volume.
Once initiated, the Prime operation will move the desired amount of fluid through the system unless stopped early.
NOTE
It is recommended to perform a Dispense in the desired Production Mode after a Prime operation in order to
properly setup the fluid for repeatable dispenses.
3.2.4 Display
The display provides an operator interface to all operating parameters in the Controller Module. New values can be
entered and current values displayed for all the functions of the system. The current operating mode and system
status are shown on the display. The display contains multiple interface screens each providing information to the
operator.
The display shows system status, settings and general information. The display is divided into six fields as shown.
Following is a description of what will be displayed in each field.
