Description

The Scilogex SCI40-S LED Overhead Stirrer is a stirring system that is both high-performance and equipped with a diverse array of features to satisfy the needs of contemporary laboratories. It is equipped with a robust motor that can generate stirring velocities of up to 2000 RPM, guaranteeing consistent and thorough mixing. The mixing process is easily monitored due to the exceptional visibility provided by the LED illumination system. The stirrer is also equipped with a digital display that enables users to easily modify the speed and monitor the current speed. It is an optimal choice for laboratories with restricted space due to its lightweight construction and compact design, which facilitates movement and storage.

System Assembly

Install stand

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

Install stirring impeller

Plug the stirring impeller into the drill chuck, and adjust the depth of the stirring impeller into the vessel. Rotate the drill chuck with your fingers to fix the stirring impeller, and then tighten the drill chuck clockwise evenly using the chuck key.

Note

The overhead stirrer is a high-speed running device. The system requires securely locking the corresponding components in each step of the assembly to avoid any movement of the main unit or stirring impeller, which could cause harm or damage to peripheral instruments and personnel.
The stand is a support device for the overhead stirrer. The corresponding components need to be locked securely to avoid any movement that could cause harm or damage.
When installing the main unit and anti-drop protector, take care of your fingers to avoid injury.

Overload Protection

The overhead stirrer works continuously; the motor current is electronically limited to achieve security stall and overload protection. When the torque reaches a limited value, the overload protection function will start. At the same time, the overload protection light flashes.

Starts overload protection
- When the setting speed value does not match the current medium viscosity, overload protection starts.
- When the motor output shaft is stuck, motor protection starts.

Interface and Output (LCD Digital)

The OS40(20)-Pro Overhead Stirrer makes use of special accessories and cables to connect to external devices. A standard 9-pin interface is used to connect to the PC.
The cable between the overhead stirrer and PC is 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 start bit; 7 character bits; 1 stop bit.
- Transmission speed: 9600 bit/s
Data communication from the laboratory instrument to the computer is only possible on demand from the computer.

Note: Do not insert or remove the RS232C communication line when the instrument is switched on!
