General Information
Orbital shakers PSU-10i and PSU-20i are benchtop multifunctional shaking units.

Shakers are designed with direct drive brushless motor, with warranted service life of
35000 hours. Units are reliable in operation and provide stable non-stop shaking for 7 days.
Shakers are equipped with a liquid crystal display that shows set and current time and speed
values. Variety of platforms, wide speed range and high maximum load (3 kg for PSU-10i
model, 8 kg for PSU-20i model) expand the possibilities of application of orbital shakers in
different laboratories.
PSU-20i model provides three types of motion, which can be performed individually,in pairs or set in a repeated cycle.
Orbital rotational motion. Simple orbital motion with an option of shifting
direction (clockwise/anti-clockwise) after set time. Adjustable speed from 20 to
250 rpm (increment 5 rpm). Time setting range 0 - 250 s or non-stop.
Reciprocal motion. Orbital rotation with changing direction of rotation.
Adjustable amplitude (from 0° to 360°, increment 30°) sets the limits for thistype of motion. The speed is the same as set for rotational motion (from 20 to
250 rpm). Time setting range 0 - 250 s or non-stop.
Vibro motion. Intensive mixing of samples at high speed with small
amplitude - Vibro motion. Adjustable amplitude (from 0° to 5°, increment 1°)
sets the limits for this type of motion. Time setting range 0 - 5 s or non-stop.
Reciprocating and Vibration motion types can be replaced with a pause.
All 3 motions are combined into a cycle (fig. 1) and can be used:
separately;in combinations of two types;
all three in one cycle.
By combining different types of rotationalmotion, the researcher gets unlimited options for mixing
parameters. The countdown timer is used to control theoperation time, with the period from 1 min to 96 hours.

Working with model PSU-10i.

Figure 2. Control panel of PSU-10i

5.1.1. Connect the external power supply to the mains. Switch the power switch on the rearside of the unit into position I (on).
5.1.2. Place samples on the unit platform.
5.1.3. Set the required working time interval in hours and minutes (the increment is 1 min)using the ▼ and ▲ Time keys (fig. 2/1). Pressing the key for more than 2 s will
increase the increment.
5.1.4. Set the required shaking speed (the increment is 10 rpm) using the ▼ and ▲ RPM
keys (fig. 2/2). Pressing the key for more than 2 s will increase the increment. The
set speed is displayed in the upper line of the display.
5.1.5. Press the Run Stop key (fig. 2/3). The platform starts rotation, indication RUN
appears on display and the timer in the lower line of the display starts counting thetime interval.
5.1.6. After the timer reaches the set time, the platform motion will stop and the flashingindication STOP, accompanied by the repetitive sound signal, will appear in the lower
line of the display. Press the Run Stop key to shut down the signal.

5.1.7. The unit can be stopped before the set time elapses if necessary by pressing the Run
Stop key. Press the Run Stop key to repeat the operation with the same working
time and speed.
5.1.8. If the working time is not set (or is reset) and the Time indicator on display shows
OFF, pressing the Run Stop key will start continuous operation of the unit until the
Run Stop key is pressed.
5.1.9. The platform motion can be stopped at any time by pressing the Run Stop key. In
this case, the program realization and the platform motion will stop and the unit willswitch into the STOP mode.
5.1.10. After finishing the operation, switch the power switch on the rear side of the unit into
position O (off) and disconnect the external power supply from the mains.
5.2.

Working with model PSU-20i.

Figure 3. Control panel of PSU-20i

5.2.1. Connect the external power supply to the mains and switch on the Power switch (fig.
3/6).
5.2.2. Place samples on the unit platform.
5.2.3. Set the appropriate program and operation time (see section 6. Program Setting)according to the methodical prescriptions.
5.2.4. Press the Run Stop key (fig. 3/5) to start the program. The platform motion starts,
the indication RUN (fig. 3/2) and the changing time values are shown on the display.
5.2.5. If the operation time is set, the unit stops after the set time interval expires. Flashingindication STOP appears on the display, and an audible signal starts, indicating theend of operation. Press the Run Stop key to stop the signal.
5.2.6. If the operation time is not set and the timer indicator (fig. 3/1) shows OFF, pressing
the Run Stop key causes the unit to operate continuously until the Run Stop key ispressed again.
5.2.7. The rotator can be stopped at any time during operation before the set time expires
if necessary by pressing the Run Stop key.
5.2.8. Press the Run Stop key to repeat the set program.
5.2.9. At the end of operation switch off the unit using the Power switch and unplug theexternal power supply from the mains.

This section is only for model PSU-20i.

The program consists of cycles. Each cycle includes up to three different types ofplatform motion (Orbital, Reciprocal and Vibro) set one after another with the durationfrom 0 to 250 seconds for Orbital and Reciprocal motion types and from 0 to 5
seconds for Vibrating motion.
It is necessary to set speed, amplitude, time for each motion type and the overall
operation time.
Press the Select key (fig. 3/3) to choose the parameter to change. Each pressing of
the Select key consecutively activates the parameters. The active parameter isflashing. Use the ▼ and ▲ keys (fig. 3/4) to set the necessary value. Pressing the
key for more than 2 s increases the speed of value change.
Saving the program does not require additional operations, because the microprocessor saves the last parameter changes as the working program automatically.
If the time for a motion is set to 0 s (indication OFF), this type of motion will be skippedin the cycle.
It is possible to set a pause instead of Reciprocal (0–250 s) or Vibro (0–5 s) motion.
For a pause, set the amplitude of Reciprocal or Vibro motion to zero and set the time
for this motion, which will be the time of pause duration. During the operation, theplatform will not move in this mode but the time will be counted down.
The timer (fig. 3/1) is used to control the overall operation time. The timer can be set
for the period from 1 min to 96 hours (timer increment 1 min)Note.
The set time cannot be changed during operation.

6.9.1. Orbital motion. Set the speed (fig. 4/A, 20–250 rpm) and time (fig. 4/B, 1–250 s) ofOrbital motion. Turn off Reciprocal motion (fig. 4/C) by setting time of the cycle tozero (OFF). Turn off Vibro motion (fig. 4/D) by setting time of the cycle to zero (OFF).

Figure 6.

Note:The unit is programmed to change the rotation direction each time
when a motion timer is started, i.e. if the Orbital motion time is set to
30 s then the direction of orbital rotation will be changed every 30 s
(fig. 5).
If Orbital motion time is set to 0 s, shaker will perform simple orbital
rotation in one direction (fig. 6). In this mode, Reciprocal and Vibro
motion cannot be added to the cycle.
6.9.2. Orbital + Reciprocal + Vibro motion. Set the speed (fig. 7/A, 20–250 rpm) and time
(fig. 7/D, 1–250 s) of Orbital motion. Set the amplitude (fig. 7/B, 0–360°) and time (fig.
7/E, 1–250 s) for Reciprocal motion. It is performed at the same speed as the Orbital
motion (fig. 8). Set the amplitude (fig. 7/C, 0–5°) and time (fig. 7/F, 1–5 s) for Vibro
motion.

Figure 8.

6.9.3. Orbital + Reciprocal + Pause. Set the speed (fig. 9/A, 20–250 rpm) and time (fig.
9/D, 1–250 s) of Orbital motion. Set the amplitude (fig. 9/B, 0–360°) and time (fig.
9/E, 1–250 s) for Reciprocal motion. It is performed at the same speed as the Orbital
motion. Set the amplitude (fig. 9/C) of Vibro motion to zero. Set the time for Vibro
motion (fig. 9/F, 1–5 s), this is the time of pause duration (fig. 10).

Figure 9.

Figure 10.

6.9.4. Vibration + Pause. Turn off Orbital motion by setting time of Orbital motion below
zero (fig. 11/D, OFF). Set the amplitude of Reciprocal motion (fig. 11/B) to zero. Set
the time for Reciprocal motion (fig. 11/E, 1–250 s), this is the time of pause duration.
Set the amplitude (fig. 11/C, 0–5°) and time (fig. 11/F, 1–5 s) for Vibro motion. See
figure 12 for process visualization.
