If the transmitted set value is within the permissible range, the Shaker will start shaking at the
chosen frequency. The shaking motion is cut off by setting the value to 0.
If the Shaker is to be operated manually again, the remote control mode has to be switched off
via a PC signal. The PC symbol in the display disappears.
4.3.1 Interface protocol
For operation of the RS 232 interface, an interface protocol is available on request. Please advise
model and serial numbers of the Shaker.
4.3.2 Software
The comprehensive labworldsoft software enables regulation of the shaking frequency via PC.
Complete measurement configuarations can be memorized with all necessary parameters.
Ready-to-use measuring procedures for various applications are pre-configurated and easily
retrievable.
Set and actual values of the shaking frequency are available as output signals. Data input is
made online and can be displayed either graphically or numerically.
5. Functional description
A microprocessor controller regulates the shaking frequency of the Shaker in continuous or timed
operation. The Shaker can be operated manually via the control panel as well as in remote
control mode via PC.
All models are equipped with ac motors, protected against overload. The electronic frequency
control ensures a gentle start-up, irrespective of load.
A stable and durable mechanical construction serves to impart the torque of the motor with the
specific shaking motion to the shaking platform.
The four plastic pins on the shaking platform serve to fix the accessories, see chapter 11 –
accessories – of these operating instructions.
6. Servicing, maintenance and clearing possible defects
Please make sure that no fluids come into contact with cable
connections or the electrical parts of the inside unit!
Before cleaning and/or opening the unit (only by an electrician!)
always pull the plug from the mains socket.
Danger of electrical shock !
Exchanging the fuses
The two fuses of the shaker are situated in a drawer below the unit plug. In order to check or to
exchange these fuses, press the fixing clips on both sides of the drawer and pull.
The fuses may only be exchanged against fuses of the same type. Information on the fuse
type can be found on the nameplate next to the unit plug and in the spare parts list of
these operating instructions.
Breakdown in case of overload and mains failure
Overheating of the shaker due to overload will cause the shaker to be switched off.
Caution, the unit will restart automatically after cooling down.
After a mains failure, the Shaker will not restart automatically, but has to be restarted as
described in chapter 4.2.
If the Shaker fails due to any kind of breakdown, the main switch at the back of the unit must by
all means be switched off before it is touched.
