Shaker carries an object to conduct linear or circular motion at different speeds, and then mix
the material.
Fig. 1 is the schematic diagram of Shaker SK-O/L330-Pro. There are Speed display, Time
display, speed control knob, and timer knob on instrument control panel; power switch, on
the side of instrument; After properly connect the power cord and turn on power switch,
users set experimental conditions on the control panel by speed control knob and timer
knob, and real-time observe parameters setting values and actual values on screen.

PCB etc.; Motor Modules: motor, Counterweight, Support, Eccentric Axis, Bearing, Turnplate etc.;
Rocker Module: Rocker Plate, Rocker Panel, Shrapnel, Bracket etc.; Upper Guard Module: Upper
Guard, LCD PCB, Knob etc.
Power supply: 220/110V → power outlets → PCB → system control power supply
Movement: motor drives Movement Module to rotate. According to a different lock screw
location on Rocker Plate, the movement pattern of shaker is different.
Speed feedback: the motor speed is accurately measured by the Shaft Encoder fixed on the
motor along with photoelectric switch and a feedback is given.
LCD display: LCD PCB is connected to Master Control Board and displays user’s settings
and current equipment operation information.
Chapter 2: Removal and Installation of Instrument
When instrument failure occurs, first, you should conduct a failure analysis; if the failure is caused
by the damage of instrument hardware, the related component must be repaired or replaced. Here
are the relevant contents of the replacement and disassembly of instrument.
2.1 Removal
Tool：Cross screwdriver, Diagonal Pliers, Allen key, socket spanner
Step 1:
Turn the instrument upside down,
remove the screws at the red circle
icon;

4
Step 2:
Remove the screws marked by red
circles for retention (SK-O330-Pro).
For linear shaker (SK-L330-Pro),
remove the screws marked by green
circles for retention;
Step 3:
Lift the Upper Guard from the right,
and pull out 3 ribbon cables at the
red ellipse icon;
Step 4:
Turn the Upper Guard upside down
as shown in the Figure, and place it
on the clean desktop. The places
marked by the red circles are the
positions of pillar cushion of
circular shaker (SK-O330-Pro); The
places marked by the green circles
are the positions of pillar cushion of
linear shaker (SK-O330-Pro);

2.3 Replacement of master control board
Step 1:
As shown in the left figure,
remove the 4 screws and keep
them well, unplug the connector,
then replace a new master control
board, assemble in sequence.

2.4 Replacement of motor component
Step 1:
As shown in the left figure,
remove the 3 screws marked by
red circle, remove 3 screws in
the symmetrical side and keep
them well.
Step 2:
Remove the 4 screws marked by
red circles and keep them well,
take down shaker frame.
Step 3:
Take down belt, as shown in the
left figure, remove the 4 screws
marked by red circle, then
replace motor component.

2.5 Replacement of photoelectronic switch
Step 1:
Unplug the cable marked by red
circles on MS-Motro Board, as shown
in figure;
Step 2:
When you replaced new
photoelectronic switch, the Shaft
Encoder on the motor must match
with photoelectronic switch. When
motor is turning, Shaft Encoder
cannot be frictional contact with
Photoelectronic. After Shaft Encoder
is in place, lock it with screws.
2.6 Replacement of power board component
As shown in the left figure, unplug
the connector marked by blue
circles, remove the 8 screws marked
by red circle and keep them well,
then replace new power board
component.
2.7 Replacement of motor drive board
As shown in the left figure, unplug
connectors marked by blue circles,
remove the 4 screws marked by red
circles and keep them well, then
replace a new motor drive board.

Chapter 4: Test Method
4.1 The instruments does not move
Step 2: Detection of moving parts
Visually inspect if the steel strip of
Bracket Module is broken. If no
problem, remove the Bracket Module
and visually inspect if the belt is loose or
out of position. After the motor is
powered on, examine whether it is
running, and the belt drives
counterweight to rotate. If Bracket
Module, belt, and counterweight has no
problem after visual inspection, you need
to replace the motor and MS-Motor
Board.
4.2 Instrument speed is not accurate
Step 1: Check Photosensor connections
Check if Photosensor is reliable
connection with and MS-
Step 2: Check Photosensor position
Check if Photosensor plate welding wire is
open circuit, and check whether the fixed
screws of Photosensor are loose. Adjust
Photosensor position and fix Photosensor.
If the problem remains unresolved, replace
Photosensor.
