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!
