MAGSTIR GENIE PROGRAMMABLE MAGNETIC STIRRER INSTRUCTIONS

The MagStir Genie Programmable Magnetic Stirrer features four (4) modes: Manual, Automatic, Profiles, and
Setup. Manual mode provides basic stir, stir reverse, and timer functions. The Automatic mode operates from
one of four (4) user-programmable profiles. Profiles mode allows users to create, edit, and store parameters to
be used in Automatic mode. Setup mode stores global parameters for manual operation.

FEATURES OF THE MAGSTIR GENIE PROGRAMMABLE MAGNETIC STIRRER

· Display: 2 lines by 16 characters LCD Display

· Buttons: 6 membrane switches

· Audible alarm

· Speed range: 10 – 1800 RPM.

· Cycle time: – 1 sec – 99hr

· Power Levels: – Low/Medium/High

· Selectable Ramp Rates: – 5 – 300 RPM/sec

· Memory: 4 User-Defined Profiles (manual operation also available)

MENU NAVIGATION

Values are changed by placing the cursor under the digit to be changed (by pressing the next key). Use the up
and down arrows to change the value under the cursor. The basic principles of the menu navigation are widely
used in many consumer products. In essence, the functionality of the buttons is as follows:

· START/STOP – Power On/ Start Cycle/ Stop Cycle

· MENU/OK – Accept Values

· UP/DOWN – Change values/ Toggle between options

· NEXT – Select next parameter/value to edit

· ESC – Go back/Escape to Main Menu

BASIC OPERATION

· The MagStir Genie will enter “Sleep” mode as soon as the unit is plugged into an external power supply.

· Press the START/STOP button to activate the LCD display. The current software version will be displayed,
followed by the Manual mode parameters.
Press the ‘ESC’ key to access the main menu. The four modes will be displayed: Manual, Automatic, Profiles,
and Setup. Press the ‘NEXT’ key until the blinking cursor is under the desired mode, then press ‘MENU/OK’ to
enter the mode.

MANUAL MODE:

Manual mode provides basic stirring, stir reversing, and timer functions.
a) Values for speed, stir direction (D=single direction, R=reverse direction plus pause), and time may

be edited by moving the blinking cursor under each digit of the desired parameter with the ‘NEXT’
key and pressing the ‘UP’ or ‘DOWN’ keys to achieve the desired setting. Speed range is 10 – 1800
RPM, time range is 1 sec – 99 hrs.

b) Press ‘START/STOP’ to initiate the stir cycle with the displayed parameters. Pressing

‘START/STOP’ again during the stir cycle will interrupt the stir cycle and reset the time. NOTE:
Stirring action will decrease according to the ramp rate (stored in SETUP mode).

c) If reverse direction stirring is enabled (“R”), it will work with the parameters (reverse time and pause

time) stored in SETUP mode. Reverse Period: The time to stir in reverse direction in manual mode.

d) Speed may be adjusted during the stir cycle by pressing the ‘UP’ or ‘DOWN’ keys. Stirring speed

will be adjusted in increments of 50 RPM.

e) At the completion of the timed stir cycle, the MagStir Genie will stop and beep three (3) times.

AUTOMATIC MODE:

Automatic mode activates one of four (4) user-defined profiles (see PROFILES mode for more information)
stored in memory.

a) Select profile 1-4 by pressing the ‘UP’ or ‘DOWN’ keys until the desired parameter number is

displayed.

b) Press ‘MENU/OK’ to accept the profile.
c) Press ‘START/STOP’ to begin the stirring profile. (Parameters may only be changed in PROFILES

mode).

d) If ‘START/STOP’ is pressed during the stir cycle, the cycle will cease and the display will return to

the profile selection screen.

e) At the completion of the programmed stir cycle profile, the MagStir Genie will stop, beep three (3)

times, and return to the profile selection screen. NOTE: If a profile is set to ‘Repeat’, it will continue
to cycle the profile until ‘START/STOP’ is pressed.

PROFILES MODE:

Profiles mode is for the creation, editing, and storage of up to four (4) user-defined profiles, which can be
activated in AUTOMATIC mode. Each profile may consist of up to nine (9) independent steps. NOTE: If
the last step is ‘Repeat’, the program will cycle continuously until ‘START/STOP’ is pressed.
a) Select the profile to be edited (1-4) by pressing the ‘UP’ or ‘DOWN’ keys until the desired parameter

number is displayed. Press ‘MENU/OK’ to accept the profile.

b) Set ramp speed for profile by moving the blinking cursor under each digit of the speed with the

‘NEXT’ key and pressing the ‘UP’ or ‘DOWN’ keys to achieve the desired setting. Ramp speed
range is 5 – 300 RPM/Sec. NOTE: Large stir bars and/or viscous fluids require slower ramp up

times to ensure that the stir bar remains securely within the magnetic field.
c) Press ‘MENU/OK’ to accept the ramp speed.
d) STEP 1 (S1)

a. Select parameter type by pressing the ‘UP’ or ‘DOWN’ keys until the desired parameter

type is displayed. Press ‘MENU/OK’ to accept the type. Parameter types are as follows:

stirring speed for profile by moving the blinking cursor under each digit of the speed with
the ‘NEXT’ key and pressing the ‘UP’ or ‘DOWN’ keys to achieve the desired setting.
Stirring speed range is 10 – 1800 RPM/Sec. Press ‘MENU/OK’ to accept the stirring
speed. The next display will prompt for stirring time. Set stirring time for profile by
moving the blinking cursor under each digit of the time with the ‘NEXT’ key and pressing
the ‘UP’ or ‘DOWN’ keys to achieve the desired setting. Stirring time range is 1sec –
99hrs. Press ‘MENU/OK’ to accept the stirring time.

c. IF PAUSE is chosen, the next display will prompt for pause time. Set pause time for

profile by moving the blinking cursor under each digit of the time with the ‘NEXT’ key
and pressing the ‘UP’ or ‘DOWN’ keys to achieve the desired setting. Pause time is
1sec – 99hrs. Press ‘MENU/OK’ to accept the pause time.

d. If END is chosen, go to step f. NOTE: This should always be the last step programmed

to signify the end of the stir profile.
e) Subsequent steps (S2 – S9) may be entered in the same manner.
f) Set the profile to repeat, if desired, by pressing the ‘UP’ or ‘DOWN’ keys until the desired parameter

type (Yes or No) is displayed. Press ‘MENU/OK’ to accept.

g) The profile is now saved.

SETUP MODE

Setup Mode allows users to edit and program default parameters for manual operation. The following can be
programmed:
