3.2 OPERATION
The Controller Module provides the controls for producing liquid 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.
IVEK units have custom designed stepping motors and pumps sized to the specific dispensing application to provide
the proper torque and speed.
Volume commands for the Controller Module use number of full revolutions. Rate commands are in revolutions per
minute. The typical resolution of the pumps used is 200 steps per revolution, or 1.8° per step.
3.2.1 Drive System
All operational parameters on the Controller Module are programmed through the touchscreen. Total electronic
control allows for full accountability of cumulative volumes dispensed.
3.2.2 Touchscreen
The touchscreen 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 touchscreen contains nine different
operator interface screens with each providing information to the operator. Start and Stop buttons appear on two
screens for starting and stopping the system.
3.2.2.1 Introduction
Configurations - A configuration is a collection of the operating parameters required to operate the system. The
operating parameters include volume, rate, direction and drawback. For each configuration, the parameters are stored
in the configuration database. All channels use the same value for a given parameter.
Buttons - A button initiates a command being sent to the IVEK Multispense 900 Controller Module. The "Start" and
"Stop" area in the Main screen (Figure 3.8) are examples of buttons.
Boxes - A box looks identical to a button, but provides information only. Pressing a box will have no effect on the
system. The "CHANNEL" and "DESCRIPTION" area in the Fault Screen (Figure 3.13) are examples of boxes.
Screens - There are nine screens used to setup, operate and exit the system as shown in Figure 3.3. Each screen
contains information relating to operating the system. The screens and a brief description are as follows:
Main Screen Volume, Rate and Drawback settings are viewed here. The system can be operated from this screen.
Volume & Rate Screen Volume and Rate settings are viewed and changed here. The system can be operated from this
screen.
Configuration Screen Configurations are changed and stored with this screen. Any parameters changed outside the
configuration will not be saved as a configuration.

The Params B screen displays additional parameters not displayed in the Params A screen. This screen is used to
change the permission access and exit the software. The current permission level determines which buttons are
currently available as shown in Figure 3.12.
If the system uses Microspense motor/bases, view and change the current Acceleration value here. If the systemuses
standard or Heavy-Duty motor/bases, this area of the screen is blank. Most applications will use Standard
acceleration. Applications using single -stroke dispense and have a small volume being ejected from the dispense tip
may benefit from Fire-Off acceleration. High-viscosity fluids will not benefit from Fire-Off acceleration, and may stall as
a result of the reduced torque.
Information is displayed which may be requested by IVEK's Technical Service Department when locating the source
of problems. The software version of the Master Plug-In and Channel 1 Plug-In(s) and Touchscreen are displayed.
The serial number of the Controller Module is stored in the Touchscreen (entered during manufacture at IVEK
Corporation.
Insure the motor/base type (Microspense versus Standard and Heavy Duty) displayed on the touchscreen matches
the Controller Module Channel Plug-Ins and Motor/Base Modules being used. This insures the maximum and
minimum limits on values in the touchscreen matches those in the Controller Module.
The Main screen is accessible from this screen.
