7 Operation

7.1 Switching on the device

Plug the power cord into its socket on the rear panel, now connect the power cord to AC power output. Now switch ON the mains and switch ON the stirrer from the front side, as shown in figure. The power LED on its front panel will glow.

OFF ON

Important Note: Values of any parameter or mode will get set saved only after the respective display blinks for 5 times.

7.2 Setting time

The time in the display will show in minutes. The stirrer timer set for operation is in between 1 min to 999 mins and infinite. Infinite time is seen as “)(”. To set time, press “TIME” button and then set the value by pressing “+/-” button. When time button is pressed, the “Mins” display will blink indicating the time value is selected. Once time value is selected, single press “+/-” will increase or decrease time value by 1min.

Long press increment or decrement button to quickly increase or decrease time value. Time value gets saved after 5 blinks. The timer is a countdown timer showing remaining time left. Once time is over, the stirrer stops.

7.3 Setting speed

Speed is displayed as RPM. The minimum and maximum speed of stirrer is 200 RPM and 2200 RPM respectively. When the equipment is used for the 1% time, the speed will be set to zero and shown as "0". Once speed value is selected, single press "+/-" will increase or decrease speed value by 10 RPM. Long press "+/-" to quickly increase or decrease speed value. Speed value gets saved after 5 blinks.

7.4 Slip Detection Mode

To activate the slip detection mode single press the "SLIP" which makes the LED near the "SLIP" glow indicating that slip detection mode is activated.

Working of Slip Detection Mode

When the slip detection mode is active and if the stirrer bar slips away from the stirring motion, then the system will restart by reducing the value of SET RPM by 100 RPM. If still the stirrer bar slips then again the system will restart by reducing the SET RPM value by 100 RPM till 200 RPM (minimum value).

Note : This is applicable only when the speed reaches the SET RPM. It is not applicable during its RAMP UP or RAMP DOWN.

7.5 Pulse Mode Operation

Press "Pulse" to start pulse mode operation. In pulse mode, the stirring direction will change between clockwise and counter-clockwise direction for every 30 seconds which can be set from 30 to 99 seconds. Upon the selection of "PULSE", pulse button will glow. Again press the "Pulse" button to STOP pulse operation.

Programmable Pulse Mode Operation

By default, the pulse mode cycle time is 30 seconds (i.e. 30 seconds clockwise and 30 seconds anti-clockwise). With programmable pulse mode, the user can modify cycle time from 30 secs to 99 secs. Long press the pulse button to select pulse mode cycle time. The time display will change to "s 30" where "30" means pulse cycle time in seconds - this indicates that user can now modify pulse cycle time. Then press increment or decrement button to modify cycle time between 30 secs to 99 secs.

7.6 Program Mode

Program mode operation is the feature which allows user to save 99 programs which can have different speed parameters. The user can use any of this program simply by turning ON the program mode.

To turn ON the program mode, Long press "PROG" the display will blink and show "P01" indicating program mode is activated. The user can select any program from "P01 to P99" by pressing "+/-. Once required program is selected, press "Speed" to select and set speed value, press "Time" to select and set time value.

Once all values are set the display will blink 5 times and after that, all the selected values of different parameters will get saved in respective program. If the user wants to set another program then while the display is blinking press the “+/-” to move to the next program and set the values in next program. If the user wants to modify previously saved program than first Long press the “PROG” to activate program mode, select the program which you want to modify by pressing “+/-”

Now the selected program will show previously saved values of parameters. The user can change the values of parameters as per need, once all parameters are fed, the program will be saved automatically with new values after the display showing the selected program number blinks for 5 times.

7.7 Line Program selection

To turn ON the line program, long press "PROG" button. The user can find LP 1 either before P01 i. e, by pressing "-" button or after ATS mode i. e, by pressing "+" button. After selection of LP 1, the user can set all parameters like speed & time and then the selected program will get saved after 5 blinks. After filling all the parameters in LP 1, LP 2 will appear and the user can repeat the above process to save all the parameters. This particular product has 5 line programs.

After user inputs all the parameters in the line programs as per his/her discretion, press "START" to run the line programs.

If user wishes to save and run only 2 line programs or 3 line programs etc., he/she can set the value as per the number of line program and when screen goes to the next line program, set speed value to 0 (zero).

Then by pressing time button select END at time display by pressing “+/-” button to end further addition. Following this, home screen would be displayed and the user can run the Stirrer.

7.8 Auto Restart Mode

In the case of power failure or disconnection of AC power cord, when stirrer is restarted the previous set values of parameters will appear on display but it will not count the time for which it has already been used. To keep the count you have to operate the stirrer in Auto Restart mode.

To select Auto Restart Mode, Long Press the “PROG” to enter into program selection menu. In program mode between P99 and P01 Auto Restart Mode can be selected by pressing “+/-”. The display will show “ATS” indicating that the Auto Restart Mode is activated.

7.9 Keypad Lock Mode

This mode is useful when the user doesn't want to change set values of parameters while the stirrer is operating. This mode enables you to lock your operating keys. By Long Pressing the "LOCK" this mode will be activated which is indicated at RPM display which shows "L ON".

After setting the values of parameters and activating Keypad Lock Mode press "Start" to start the operation of the stirrer with the keypad lock. While operating stirrer in Lock Mode only the "Start/Stop" and "Lock" will remain active and rest of the buttons will not operate when the stirrer is running.

To deactivate Keypad Lock Mode long press the "LOCK" and the "RPM" display

will show "L OF" indicating Keypad Lock Mode is deactivated.
