only the T-handle wrench to tighten the screws. Torque these screws to 10
ft-lbs. Check these screws monthly if the unit is operated at or near
maximum speed (525 RPM).
s
Each Flask Clip up to 6.0 liters in size comes with a metal spring that must
be installed onto the clip. For flask clips through 500 ml, insert the end of
each spring into the holes at the top of the clip leg (Figure 1-11).
The 2 liter, 2.8 liter, 4 liter, 5 liter, and 6 liter Flask Clips use two sets of
metal springs and rubber spring tubes. On these larger clips, the springs are
installed by hooking their ends together as illustrated in Figure 1-12. The
upper spring and spring tubes should be installed prior to mounting the
clip to the platform. The lower spring and spring tubes, however, are
placed around the bottom of the clip legs after the flask clip is fastened to
the platform.
Note that the rubber spring tubes are placed between the clip legs.

and temperature information one minute after power is first applied to the
unit, then every 60 minutes thereafter unless the shaker receives either a
<Ctrl><Q> or a <Ctrl><S>.
The shaker’s microprocessor responds to two commands from the remote:
<Ctrl><Q> (XON)
The shaker will immediately transmit time, speed, and temperature data
upon receiving a <CTRL><Q> and will reset the 60 minute data
transmission interval timer.
<Ctrl><S> (XOFF)
The shaker will stop serial data transmission upon receiving a <Ctrl><S>
until a <Ctrl><Q> is received or power is cycled.
An internal SPDT relay is provided to monitor alarms and is connected by
a RJ-11 (telephone style) jack on the rear of the cabinet. The remote alarm
provides NO (normally open) and NC (normally closed) output. Figure 116 identifies the pin contacts and may be wired to a central remote alarm
location or to an independent alarm system. Figure 1-15 identifies the pin
contacts. Figure 1-18 shows the location of the Remote Alarm Connector.

Section 2 Operation
Figure 2-1. Front View
Model SHKE435HP and SHKE436HP shakers are microprocessorcontrolled incubated orbital console shakers designed to accommodate a
wide variety of flasks, test tubes and other glassware. The control system is
easily programmed and stores the user-defined time, temperature and
speed settings in battery-supported memory that remain even when the
shaker is turned off and unplugged.
The platform speed controller continuously adjusts for line voltage
fluctuations and provides smooth transitions with consistent control. The
circuitry is designed to slowly bring the platform up to speed and down to
a stop to prevent liquid splashing from flasks or test tubes.
An insulated lid with viewing port is counter-balanced for easy opening by
hand or foot pedal. A safety interlock requires that the lid be closed for the
drive motor, circulating fans and heating elements to operate.
Caution It may take up to one minute to bring the platform up to full
speed. Never leave the shaker unattended when starting it.
Caution Make sure all flasks and test tube racks are firmly seated in the
clips and check the security of the flask clip and platform attachment
screws monthly.
Caution Do not operate the shaker at maximum speed without a load.

Control Panel Operation
The control panel on these units has a liquid crystal display and eight
operating buttons which are identified by word and symbol. During
programming, the up and down arrows increase and decrease the
numerical values of time, platform speed, or temperature. Press and hold
either arrow to cause the values to scroll in that direction; hold for more
than five seconds to increase the scrolling speed.
When changing the system configuration, the down arrow advances the
display to the next screen while the up arrow returns the display to the
previous screen. Pressing the Time, RPM or Temperature button selects
the parameter above it to be changed, while the up and down arrows
increase and decrease the numerical values, respectively, or toggle between
two different options. Pressing and holding either arrow will cause the
values to scroll in that direction; holding for more than five seconds will
increase the scrolling speed.
The START button begins platform operation as defined by the Time and
Speed setpoints, while the STOP button halts the platform. Chamber
temperature control begins upon power-up as defined by the Temp
setpoint.
The alarm indicator and alarm silence button complete the shaker control
panel. When in alarm, the unit sounds an audible warning and flashes the
three red indicators. Depending upon the error detected, pressing the
Silence button turns off the audible alarm. However, the three red
indicators continue to flash until the alarm condition is corrected. For
most alarms, the audible warning will sound again in about fifteen minutes
if the condition persists.
The alarm features are discussed in more detail in the “Shaker Alarms”
section of this manual.

For convenience, the audible tone is muted by pressing the Silence button,
but rings back in about 15 minutes, for most alarms, if the alarm
condition is still present. However, the alarm indicator lights and alarm
messages continue until the alarm condition is corrected by the operator.
After the root cause of the fault has been corrected, pressing the Silence
button will clear the alarm message from the display and stop the alarm
indicator lights from flashing. The audible tone will ring back in about 30
minutes for the Check Belt and Check Fuse alarms if the alarm condition
is still present. These alarm messages clear from the display when the unit

alarm message remains and the audible tone continues to sound to alert the
operator. Both the display message and the audible tone are cleared by
pressing the Silence button.
Note The alarm will not occur if the power failure is less than 15 seconds
in duration, while the unit is shaking.
s
If power is interrupted for more than 1½ hours while the unit is turned on
but not shaking, a Power Failure alarm will occur. The purpose of the
alarm in this case is to alert the user that an extended duration power
failure occurred during the Hold interval after a timed shaking operation,
or during a period of incubation only. This alarm will also occur any time
the unitis turned on after being turned off for more than 1½ hours (such
as when the unit is shipped from the factory, or when it is returned to use
after a period of storage).

RPM Tracking alerts the operator by
either alarm message shown below that
the platform speed has varied ±5 RPM.
In the alarm state, the audible alarm is
muted by pressing the Silence button, but rings back in about 15 minutes,
if the alarm condition is still present. However, the message and indicator
lights persist until the fault is corrected. Afterward, the remaining relevant
alarm components are cleared by pressing the Silence button.
Check Belt alerts the operator that the
drive belt may have broken, is slipping
because it needs tightened, or something
is slowing or preventing platform movement.
In the alarm state, the audible alarm is muted by pressing the Silence
button, but rings back in about 30 minutes, if the alarm condition is still
present. However, the message and indicator lights persist until the fault is
corrected. Afterward, the remaining relevant alarm components are cleared

temperature of the shaker has risen above
or fallen below the programmed
temperature tracking limit control point,
by an appropriate alarm message as shown.
In the alarm state, the audible alarm is muted by pressing the Silence
button, but rings back in about 15 minutes, if the alarm condition is still
present. However, the message and indicator lights persist until the fault is
corrected. Afterward, the remaining relevant alarm components are cleared
by pressing the Silence button.
Platform Stalled
Platform Stalled alerts the operator that
free platform movement is inhibited. The
motor will automatically shut off and
attempt to restart after approximately 15 seconds. In the alarm state, the
audible alarm is muted by pressing the Silence button, but rings back in
about 15 minutes, if the alarm condition is still present. However, the
message and indicator lights persist until the fault is corrected. The motor
will continue to cycle on and off until the obstruction is removed, or the

Section 3 Maintenance
The Model SHKE435HP and SHKE436HP shakers use a brushless DC
motor and oversized, permanently-lubricated bearings, requiring no
maintenance.
Gas Springs
Platform and Cabinet
Cleaning
Control Panel
Cleaning or Replacing
Air Filter
The gas springs should be checked periodically, and ideally every six
months. The opening force, as measured from the front lip from a closed
position, should be below 100 N (22.5 lbf) maximum. If the force is above
this value, the gas springs should be replaced. If a force measurement is not
possible, the gas springs should be replaced every two years.
The anodized brushed aluminum platform and powder-coated steel cabinet
surfaces can be cleaned with common laboratory materials. However, liquids
should not be allowed to enter the shaker cabinet from under the platform.
All spills should be cleaned up immediately. If necessary, remove the
platform. Follow ‘Installing the Platform’ procedure in Section 1 when reinstalling the platform.
The control panel has sealed push buttons and a liquid crystal display. It
may be cleaned with a mild detergent and dried with a soft cloth.
The air filter is located behind the grille on the front of the cabinet. The
grille is held in place by six press-in type retainers and is easily removed by
grasping it by the edges and pulling it off.
The air filter is held in place by four retaining springs (Figure 3-1) and is
easily removed. It may be washed in water with a mild detergent and dried
between two lint-free towels.

Circuit Boards
Warning Only qualified service personnel should perform this procedure. s
Four circuit boards control the Orbital Shaker. Three boards are located in
the relay tray compartment, the fourth is behind the LCD display. Figure 44 identifies the circuit boards and other major components in the relay tray.
Refer also to the relay tray wiring diagrams in Section 7.
To access the panel, unplug the shaker and move it to a sturdy location that
will allow the back of the cabinet to swing down and lie flat. Remove the
screws indicated by the arrows in Figure 4-2 and lower the back panel.
Components in the electronics panel are identified in Figure 4-4. Refer to
the parts list and the electrical schematics in the back of this manual for part
numbers.
Two temperature sensors are located behind a perforated cover plate on
the right side of the chamber. Refer to Figures 4-1 and 4-5. To access
these sensors, pull outward on the two black press-in fasteners on the top
edge of the cover and lift the cover upward. The cover is held in place with
four metal clips.

To replace the cover, make sure all four clips engage
the metal edges of the chamber and the two fasteners
are firmly seated in their holes. Press the top of the
fastener in until a “click” is heard. See Figure 4-6.

Locations of the Blower Motor and Ambient Fan Motor are shown in
Figure 4-7. Removal of the relay tray is necessary to service the Blower
Motor or the Heating Elements. Access to the heaters is through an access
port on the front of the air plenum.

Warning Only qualified service personnel should perform this procedure. s
Warning Remove and lock-out electrical power when working on or near
the relay control tray and heating element connectors. Allow sufficient time
for the heating elements to cool before
reaching into that area.
A manual reset circuit breaker is located
between the heating element electrical
connectors on the side of the air plenum.
(Figures 4-7 and 4-8) The breaker can be
reset by removing the front grille and
reaching over the relay tray.
After the console cabinet is in place and leveled, with the platform installed,
turn the unit on and set the speed to 300RPM. Kneeling in front of the
console, lightly touch the lower left and right corners of the cabinet. If one
side seems to vibrate more than the other, raise or lower the corner support
leg using the 3/4” open end wrench supplied in the parts bag. Continue this
“fine tuning” until the vibrations are reduced as much as possible.

visible after removing the grille and
belt/pulley tray (Figures 4-9 and 4-10).
Loosening the three 7/16” bolts at the base
of the drive motor allows the belt to be
changed or tension applied to the belt.
Tighten the three bolts and torque to 10 ft. lbs.

Calibrate Speed (RPM)
To remove the pulleys from their shafts, use a 1/8” Allen wrench to
remove two set screws from the belt groove of the larger pulley; use a
5/16” Allen wrench to remove the single set screw from the belt groove of
the smaller pulley.
When replacing the pulleys, seat the larger pulley completely against its
baseplate. The smaller pulley, however, is installed with 0.300” space
between it and the baseplate.
An external calibrated speed measuring device can be used to adjust the
actual platform speed so that the unit setpoint speed matches the external
device measurement. Calibration of the platform speed is performed at the
factory at 250 RPM. To change the actual platform speed, open the
Configuration menu by pressing the down arrow, up arrow, and the
Silence button, and then the down
arrow twice, in the sequence shown at
right.
The screen at right appears on the
display.
Then press the Speed button
beneath RPM.
The value shown on this screen is the present Speed setpoint. Using the up
and down arrows, increase or
decrease the platform speed until
the reading on an independent,
accurate speed measuring device
matches the Speed setpoint.
When finished, press any of the three buttons (Time, Speed, or Temp) to
save the new setpoint value and return to the previous screen, or press
nothing for about 15 seconds to save the new setpoint value and return to
the Operating Screen.

Calibrate the
Temperature
1. Place a 250ml Erlenmeyer flash (filled with approximately 100ml of
liquid) in approximately the geometric center of the platform.
2. Suspend an independent temperature measuring device of known
accuracy into the flask. The sensor should be submerged in the liquid
but not in contact with the bottom or sides of the flask.
3. Adjust the shaker temp setpoint at desired calibration temperature.
4. Set the shaking speed setpoint to 75 RPM.
5. Start the unit and allow a minimum of 2 hours stabilization of cabinet
and flask liquid.
6. Enter Calibration mode by pressing
the down arrow, the up arrow, the
Silence button. Then press the down
arrow twice. The screen at right will
appear on the display:
7. Press the Temperature button
beneath Temp.
8. Using the up and down
arrows, increase or decrease the
temperature value to match
the independent, accurate
temperature measuring device.
9. When complete, press the Time, Speed, or Temp button to save the
setting. The display will return to the Calibrate - RPM Temp screen.
(Or, if nothing is pressed for about fifteen seconds, the display will
return to the Operating Screen and the setting will be automatically
saved to memory.)
10. Allow the cabinet to re-stabilize for 1 hour. Recheck temperature. If
necessary, return to Step 6 until no additional adjustments are needed.
11. Temperature calibration is now complete. Remove calibration
equipment and resume use.
Top line displays actual elapsed run time, speed, and temperature.
Bottom line displays user time, speed and temperture setpoints alternating with any active alarm messages.

Specifications
Installation category (overvoltage category) defines the level of transient overvoltage
1
which the instrument is designed to withstand safely. It depends on the nature of the
electricity supply and its overvoltage protection means. For example, in CAT II which is
the category used for instruments in installations supplied from a supply comparable to
public mains such as hospital and research laboratories and most industrial laboratories,
the expected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V
supply.
2 Pollution Degree describes the amount of conductive pollution present in the operating
evironment. Pollution Degree 2 assumes that normally only non-conductive pollution
such as dust occurs with the exception of accasional conductivity caused by condensation.
