4. System Assembly
a. Install stand
The stand must be assembled
according to the following
instructions. Adjust the height
of the main unit, and the
distance from main unit to the
support holder by rotating the
locking device. Anti-drop
protector can be adjusted up or
down, ensure the locking
position is suitable for fixing
the main unit, and then attach

Figure 1
b. Install stirring impeller
Plug the stirring impeller into
the drill chuck, and adjust the
depth of stirring impeller into
vessel. Rotate the drill chuck
with your fingers to fix the
stirring impeller.
Figure 2
Note:
1. Overhead stirrer is a high-speed running
device. The system are required to lock
securely the corresponding components in
each step of the assembly to avoid any
movement of the main unit or stirring
impeller which would be caused harm or
damage to peripheral instrument and
personnel.
2. The stand is a support device for overhead
stirrer. The corresponding components are
required to be locked securely to avoid any
movement which would be caused harm or
damage.
3. When install main unit and anti-drop
protector, take care of your fingers to avoid
harm.

5. Trial Running
Follow the instructions below to trial operate:
LCD digital LED digital
•Ensure the required operating voltage and power supply
voltage matched.
•Ensure the socket must be earthed reliably.
•Connect the power cable，ensure the power on and begin
self-checking.
•Rotate the stirring button and set stirring speed.
•Press stirring button and start stirring.
•Press again the stirring button and stop stirring.
•Ensure the required operating voltage and power supply
voltage matched.
•Ensure the socket must be earthed reliably.
•Counter-clockwise rotate the speed control button to the
end before switch on instrument.
•Connect the power cable，ensure the power on and begin
self-checking.
•Clockwise rotate the speed control button to the target
speed value, and start stirring function.
•Counter-clockwise rotate the speed control button to stop
stirring function.
If these operations above are normal, the instrument is ready to operate. If not, the instrument may be damaged during
transportation, please contact technical support of manufacturer/supplier.

7. Overload Protection
Overhead Stirrer works continuous, the motor current is
electronically limited to achieve security stall and overload
protection. When the torque reaches limited value, overload
protection function will be started. At the same time
overload protection light flashes.
• Starts overload protection
When the setting speed value does not match the
current medium viscosity, starts overload
protection.
When the motor output shaft is stuck, motor
protection starts.
• Refer to Chapter 9 for the solutions of overload
protection and motor protection.
8. Interface and Output (LCD
digital )
LCD digital overhead stirrer makes use of special
accessories and cables to connect external devices. Standard
9-pin interface is used to be connected to the PC.
• The cable between Overhead stirrer and PC are
selected from the specified communication line of the
EIA-standard RS232C, corresponding with DIN66020.
• Transmission method: Asynchronous signal
transmission in start-stop-operation.
• Mode of transmission: Fully Duplex. 1 starts bit; 7
character bits; 1 stop bit.
• Transmission speed: 9600 bit/s
• Data communication from laboratory instrument to
computer is only possible on demand of the computer.
Note:
Do not insert or remove the RS232C
communication line when switch on!
