Extent
The present manual describes the function and operation of all possible configurations of the NOVOTRON. The
chapter about the incubation chamber, for example, has a description of the safe operation of the cooling system
which is not relevant for a simple shaker. When such specific cases occur, they will be
indicated.
1.
Safety Considerations
The NOVOTRON incubator shaker corresponds to modern demands for safe and easy-handling. Any
exposed current-carrying components are low-voltage only, switching networks are physically separated
and the chance of mechanical injuries minimised.
Nevertheless, the following basic hints are indispensable for the safety of the user and the protection of
the machine. These hints, both here and in the following text, are printed in italics in
conjunction with a warning symbol (hand with outstretched finger). They are to be followed
in every case.
All the housings and covers of the shaker are only to be removed by personnel explicitly authorised by
INFORS to do so. This is because safety-critical zones may be covered by some housing panels.
The movement of the shaker table can cause injury due to the high torque when in operation. Therefore, the
tray is only to be handled when at rest.
During long absences or interruptions to operation, according to location (eg. humid laboratory or unprotected
position), it is recommended to withdraw the mains power plug to avoid the risk of accidents.
The shaker must never be operated without a tray.
You must comply with the specifications in Chapter 4.2 "Chemical Resistance".
Neither the air intake openings at the front of the shakers nor the three ventilators in the incubator
chamber are to be obstructed in any way. On no account allow objects to become stuck in the fan or air
intake openings.
If the NOVOTRON is used as an incubator shaker without cooling, under no circumstances lift the unit by
the plexiglass chamber, resp. the edges.

2.1
Characteristics
INFORS AG
Page 5
The requirements for shakers are constantly adapting and changing. The development of small incubator
shakers has not kept pace with the demands of the market. The gap has now been completely closed
thanks to the use of innovative design and production techniques.
The result is the NOVOTRON.
In the smooth evolution of reliable, accurate and powerful shakers, the INFORS-magnetic drive has kept
up-to-date. However, with a complete revision of the system by incorporating microprocessor control, it
now offers still greater reliability.
When speed and temperature are placed under microprocessor control then features such as timed
modes of operation and and data transfer via a serial connection become possible.
The NOVOTRON's list of excellent features begins with a footprint of only 580 x 725 mm, a cooling unit
integrated with a small incubator, which allows for the widest possible range of temperature-controlled
environments to be achieved.
The NOVOTRON can - because it is front-opening - can be located both on or under a laboratory bench.
A revolutionary new system allows automatic tray release and locking.
2.2
Configuration
The NOVOTRON consists of four elements:
- an orbital shaker with a 25mm or 50mm diameter throw
- an incubation chamber
- a chiller unit with integral cooling system
- a tray of type N (475 x 420mm), which optionally accepts flask clamps, bottle holders or "sticky
matting".
The total freedom to choose any combination allows the user to select the optimal arrangement for
almost any task.
2.3
Function
The shaker has an electronic drive system which utilises magnetic coils. The coils alternately generate a
magnetic field which directly drives the shaking table and makes for a virtually silent drive mechanism.
Magnetic drive shakers were developed by INFORS to provide high efficiency, a very "slim" construction
little heat generation by the inductive system and the power to meet the widest possible range of
requirements. Apart from the bearings/eccenters on which the shaker table travels, there are no moving
parts. The eccenter also provides dynamic counterbalance for the load. The lifespan and reliability of the
shaker are naturally increased by the use of this system.
The temperature in the incubation chamber is measured using a Pt-100 sensor. Three powerful blowers
ensure optimal air circulation. They are mounted on the rear wall of the unit and bring air from beneath
the shaker table, over the heating elements and then circulate it throughout the incubation chamber. The
blower in the middle is controlled only, if the cooling is activated.
The speed control is steplessly adjustable throughout its range. A three-place digital display is used to
show both the set point and the actual value. The temperature is regulated using a proportional electronic
controller with Pt-100 sensor. Heater output is automatically adjusted in line with temperature deviations.
Therefore, rapid heating up can be achieved without overshoot.
The temperature set point is selected using a keypad in units of 0.1 °C. Set point and actual values are
shown on the same display.

Construction
The shaker has a robust and elegant stove-enamelled steel housing. The front panel is made from a rigid
polyurethane foam (CFC-free) in which the splashproof operating panel is embedded. The incubation chamber is
finished in 5mm and 8mm strong acrylic glass and is front-opening.
The cooling system is housed in a metal casing on which the NOVOTRON is mounted. It has two handles at the
front with two rollers at the rear which allow the whole unit to be effortlessly positioned under a laboratory bench.

Transport
3.1
General
INFORS AG
Page 7
The NOVOTRON should never be transported or moved by a single person in view of its heavy weight,
especially so when the unit with the incubation chamber and cooling unit must be handled. In this latter
configuration, relocation over long distances within a building using a fork lift truck or small trolley is
recommended. The equipment should only be moved by fork lift truck if it is standing on the original
palette as used by the manufacturer for delivery. Also, relocation using a small trolley must be done with
great care.
There is a danger of shearing off the shaker's feet and collapsing the bottom plate in the event of
extraordinary stress. The machine should therefore not be dragged unless the special base
support option has been fitted.
If it is not possible to transport the NOVOTRON using a small trolley, it should be carried by two adults
(observing the correct lifting techniques). Weight without tray is 65Kg.
If the NOVOTRON is configured as an incubation chamber without cooling then under no
circumstances is it to be lifted by the edges of the acrylic glass chamber.
3.2
Packing
All parts of the NOVOTRON shaker are packed in a cardboard carton. It is delivered attached to a
special palette. The packing materials are selected to be "environment-friendly". Through the purchase of
the machine the packaging becomes property of the buyer after the delivery.
The incubation chamber is packed separately from the shaker/chiller unit(s). It must be assembled and
mounted on the shaker before beginning operation (see Chapter 6).
3.3
Unpacking
Please ensure that the equipment is not damaged during unpacking, especially the incubation hood
(scratches).
4.
Location
4.1
General
The following points should be considered when choosing a location:
-
Protection from mechanical damage (small trolleys, kicks etc.)
For a shaker without cooling, the environmental temperature should not be higher than 3-5°C below
the desired operating temperature
For a shaker with cooling, the environmental temperature should not be higher than 8°C above the
minimum required operating temperature
Do not locate in direct sunlight.
The surface on which the shaker stands must be horizontal and absolutely flat.
The shaker should not be exposed to extremes of dust and dirt without additional protection. The two
air intakes at the front of the shaker must be especially protected from the ingress of dust particles.
The base on which the shaker stands must be safely positioned.
Please consider all the different connections you need to make (power supply, computer cabling).
The mains switch must remain freely accessible at all times.

Both sides are now fitted and loosely held with screws(1)
Fit the back wall (2)
Both support rods (3) are fitted and the frame pulled together by slightly tightening the M4 screws (4)
(see below).
The lid (5) is fitted from the back of the unit.
The door is pushed into the guide rails (in side plate 6) (first one side, then the other)
The door support struts are fixed to the sides by bolts (7)
Angle bracket (8) is screwed on using the M3 screw.
Note: the angle bracket can be omitted if the incubation temperature does not exceed 45 °C.
When the angle bracket is not fitted, the lid can be pushed backwards, allowing the access to the
flasks from above. Admittedly this kind of opening, even when it’s temporary, can cause a
considerable loss of temperature in the incubation chamber.
Secure the guide rods with M3 screws (10)
Tighten the side screws (1)
Arrange side plate with the elongated slots so that the door will shut tightly (the rollers of the door
should get into a little bit of traction while closing, so that they should pull back the top edge of the
door)
Be careful when tightening the screws that are in direct contact with the Plexiglass (overtightening
risks breakage!).

Mains switch
INFORS AG
Page 10
The mains switch of the equipment is to be found on the left side wall. It is an ON/OFF selection switch
which has to be turned on (position ON) first of all. If the switch is turned off (position OFF), then the unit
is completely separated from the mains power supply. When the switch is turned on it shows a green
light. At the same time, a small power symbol on the front display panel also shows a green light.
The mains switch can be left on during normal operation, even if neither the shaker nor the heating are
working. In this "stand-by" condition the unit consumes approximately 6 Watts. Frequent switching on
and off (eg. every hour) should be avoided in order to minimise the stress on the electronic components.
If the shaker is not used for several days, switching off at the mains is recommended.
The set points for all parameters (temperature, shaker speed and timer) are stored for at least one week
after switching off or during an interruption to the power supply.

Handling the panel
7.2.1.1 General
To make things clear, all the keys have only a single function which is evident from their title (except for
accessing the operating hour counter see - 11.3). Only the display -which can show both values and
messages - is, in this sense, "multi-functional"
If the mains switch is on, the equipment is already in operation.
In all cases, to make an adjustment to parameter values, the MODE key must first be selected. Then the
SET key should used along with the +/- keys to adjust the parameter. After that, the control can be
switched on. To do this you use the ON/OFF key.
7.2.1.2 Adjusting the Temperature
-
Select function "C" using the MODE key. "C" lights up in the parameter display.
The desired set point value is entered by means of SET key along with the +/- keys. The set point will
be displayed (alternating with the Status display).
Control is activated by the ON/OFF switch as long as it is not already switched on. The actual value
will be displayed (alternating with the Status display).

"Stp" (Status: stop) when the shaker is braking
"Hi" (Status: high) when the actual temperature exceeds the set point by more than 1.5 °C
"Lo" (Status: low) when the actual temperature is below the set point by more than 1.5 °C
"Err" (Status: error) when an error condition exists.
The displays for set point, actual value and "off" are always available for the parameter currently
shown in the parameter display.
A required set point value can be called up at any time by activating the SET key.
7.2.2.2 Display for Temperature and Shaker speed
The display follow the schematic as shown:

Table 1
All the information can be gathered from the display as it alternates to and fro between different
"screens";
Alternating between Temperature and Shaker speed
The alternation occurs at ten second intervals so long as no key has been pressed for a period
of 30 seconds. Inside these ten seconds you see:
Alternating between Status display and set point values (see. Table 1)
The alternation always occurs at two second intervals.
Additionally, the display of temperature deviation "Hi" or "Lo" appears when the actual temperature value
deviates more than 1.5 °C from set point (see Table 1). You find here also that the display alternates
between the status message and the actual value every two seconds.
Correct Operation: When the display alternates at 10 second intervals between RPM and C without
blinking. Rapid flashing indicates an error condition eg. a set point value not being maintained.

"Stp"
When the shaker is stopping "Stp" appears in the display. As soon as the shaker has stopped
the set point value appears.
"Opn" Appears when the incubation chamber lid is open.
"Err"
8.
Appears when the shaker table is blocked, or the temperature sensor is defective.
Operation
If the unit is set up properly (see Chapter 7. Starting the Apparatus) there is little manipulation necessary
during normal operation of the NOVOTRON, with the exception of loading the tray.
The unit operates according to the following programmes; either:
- constantly in the same mode
- Stationery until the START timer switches it on, or
- Running until the STOP timer switches it off.
The appropriate adjustments are described in Chapter 7.
The NOVOTRON runs without emissions of any kind except for the normal operational noise. Sudden
noise, smells, unusually strong vibrations and the like are indicators of defective operation and MUST be
investigated immediately.
If in doubt on seeing such emissions the unit should be turned off at the main switch and the power plug
withdrawn.
8.1
Loading the Trays
The centrifugal forces of tray movement are neutralised by a compensating counterweight. For physical
reasons the counterweight can only be balanced against a specific weight of tray.
Of equal importance is the height of the centre of gravity of the load above the tray. (a high container =
high centre of gravity , a low container = a lower centre of gravity). The higher this distance, the more the
unit runs non-optimally and will vibrate.
Although INFORS has optimised the "bandwidth" of possible loads, the following points should be
observed to minimise vibration and possible wear to the equipment:

Always load the tray as evenly as possible to distribute the weight of the flasks over the whole area of
the tray.

fig. 3
-
Flasks which are exceptionally high with an extremely high centre of gravity should not be shaken at
high speeds.

The permissible loading should normally not be allowed to exceed or fall under the following values:
< 120 U/min
> 120 U/min
0 - 18 kg (incl. weight of tray, in case of low rotations until 30 kg)
(see chapter 8.2)
Operation above or below these values does not (especially at low speeds) have an acute detrimental
effect on the unit. However, it should be avoided if possible.
A consistently higher or lower loading is definitely possible, but you must first contact your local INFORS
representative to obtain the necessary advice.

The shaker should always be operated in the appropriate "grey band". Otherwise, vibration may be
excessive and/or the set point value cannot be reached/accurately maintained.
Higher speeds for higher loads can definitely be obtained, but you must first contact your local INFORS
representative for the necessary advice.
8.3
Starting the Equipment
See Chapter 7. Starting the Apparatus
8.4
Pausing, temporary stopping of the equipment
For pausing the operation of the unit, it is only necessary to open the chamber door. This causes both the
heating and the shaker to automatically stop. This "AUTO_STOP" is factory set and be deactivated on
demand. In this case, ease contact your nearest INFORS representative for advice.
Additionally, the fans at the rear of the chamber stop to minimise the loss of temperature-controlled air
from the unit.
A factory-set brake is implemented to shorten the period between switching off and handling the tray. The
brake is activated when the door is opened; switching off the controller circumvents this.
After the incubation chamber door is closed everything restarts automatically after a short delay period
(so long as the controllers have not been switched off).
For information about the display see Chapter 7.2.2
WARNING: The movement of the shaker table can cause injury due to the high torque when in
operation. Therefore, the tray is only o be handled when at rest.

Location of the tray and handling of the interior
The table is located by a fixing at the back of the shaker platform and two "cones" (a square and a
circular projection) in the front area hold the shaker tray in position. Also, you will find a safety bolt under
the front handle which prevents the tray from accidentally coming free from the anchor points.
To release the safety bolt you need only unscrew the black cap until it comes off completeley and lift the
tray upwards. Refit the bolt when the tray has been replaced.
UNDER NO CIRCUMSTANCES START THE SHAKER IF THE TRAY IS NOT CORRECTLY
LOCATED.
When closing the incubation chamber door, it is important to ensure that the door magnet is free to rest
closely to the operating panel. Otherwise, it is likely that the unit will no longer re-start.
No containers or other objects should become lodged inside the incubation chamber, especially during
shaker operation.
When handling the tray, it must be remembered that nothing is to get into the three ventilator fans
at the back of the unit. Equally, the two air intake vents at the front of the shaker not never be
blocked.
Under no circumstances should objects be stuck in the fans or air intakes.
8.6
Alarms
Should the temperature controller determine that the actual temperature has deviated by more than 1.5
°C from the set point, an optical alarm starts:
-
8.7
Either "Lo" (too low) or "Hi" (too high) is shown on the display according to the direction of the
deviation.
Serial Communication
For queries about serial communications please discuss your requirements with an INFORS subsidiary
or directly with INFORS Switzerland. INFORS a suitable control program, namely "MULTICON" software.

Taking out of operation
9.1
Pause, temporary stopping of the equipment
see 8.4
9.2
Switching off - normal operation
If the shaker will be inactive for a short time only, simply turn off the control of the three parameters:
- To switch off a parameter function select it via the MODE key
- Turn off the control with the OFF key
- The control is switched off (eg. the shaking table is at rest).
This method of switching off is an especially comprehensive feature when a shaker without incubation
hood is being used.

Switching off - prolonged shutdown
-
Switch off the unit as normal
Unload the tray; only empty flasks can remain in the machine.
Turn off the main switch
If power remains off for longer than one week the internal memory of the unit will be erased. In this case,
all parameter values will have to be re-entered on resumption of normal use.
If the shaker is not to be used for some considerable time we recommend you take the following
precautions:
-
9.4
Clean the shaker of all liquids which may have accumulated on the base during normal operation.
Take all the usual safety precautions (protect against dirt, dust , scratches etc.
For periods of several weeks without use, withdraw the mains power plug.
"EMERGENCY" stop
If there is danger to either people or the machine turn off the main switch immediately.
In particular, there may be danger if unusual emissions are discovered (load noise, smoke, smoke,
strong smells, excessive vibration).
10.
Trouble shooting / Fault rectification
If problems arise, please read the following list and follow the instructions given:
If your shaker still does not operate correctly, or the fault is not listed please contact your nearest
INFORS representative.
"ERR" (Error) message show in the display
This indication means that:
-
the drive system i.e. the shaker table is blocked,
the Pt-100 sensor is defective,
a magnetic coil is defective.
or
or
If there are grounds for assuming the blockage was only transient, the mains switch is turned off and then
on again. This causes a "RESET" i.e. all parameter control must be activated again, but the set point
values are retained.
If the "ERR" message appears again, please contact your nearest INFORS representative for repairs.
The display does not light up
- Check that the mains switch is turned on,
if NO, then switch on and try again, if YES continue
-
Check the power lead is plugged in,
-
Check the plug for faults if found,
-
Check the power socket is "live",
if not, plug in and try again
correct and try again
if not, correct fault and try again, if power is present contact your nearest INFORS representative

The heating doesn't work
- Check if the display show "ERR",
if NO continue, if YES contact your nearest INFORS representative.
-
Check if the heating control is turned on,
-
Check if the set point value is correctly adjusted,
-
Check the incubation chamber door is closed correctly i.e. that the door magnet is able to come to
rest close to the operating panel (too large a distance will be shown by the "Opn" message on the
display).
if YES continue, if NO, switch it on and try again
if YES continue, if NO, adjust correctly and try again
The shaker drive doesn't work
- Check if the display shows "ERR",
if NO continue, if YES contact your nearest INFORS representative
-
Check the speed control is operational,
-
Check the set point value is correctly adjusted,
-
Check that the shaker table can be freely moved by hand,
-
Check the incubation chamber door is closed correctly i.e. that the door magnet is able to come to
rest close to the operating panel (too large a distance will be shown by the "Opn" message on the
display).
if YES continue, if NO switch on and try again
if YES continue, if NO then adjust correctly and try again
if YES, it turns, continue; if NO, it doesn't turn, contact your nearest INFORS representative
The parameter values cannot be reached
Check the controller for the relevant parameter function (temperature, shaker speed) has been activated
(see 7.2.1.1). The display shows "Opn" when the controller is active and the incubation chamber door is
open and when the door is closed the digits of the actual value are shown (or "Sta" during run up).
Timer operations cannot be correctly programmed
Systematically follow every instruction. Complicated programming steps should not be carried out in a
hasty manner - wait for the results! The controller needs approximately 20 seconds for complex mode
changes in the programming phase (not in normal operation) to be initialised appropriately; then the
desired results will be achieved. Note that when the remaining time is less than 10 minutes, zero will be
displayed.
11.
Maintenance/Service
11.1
Maintenance
The NOVOTRON is basically designed as a maintenance-free unit and therefore needs no regular
servicing. The shaker table works with sealed bearings, and the electronics need no maintenance.
After approximately 10,000 operating time we would, however, recommend an overhaul of the shaker by
INFORS specialists. Please contact your nearest INFORS representative when your shaker reaches this
operating time.
11.2
Cleaning of the equipment
The equipment can easily be cleaned with a damp cloth and a neutral cleaning agent. For the incubation
chamber, an antistatic plastic cleaner is recommended.
The instructions in Chapter 4.2 "Chemical Resistance" have to followed absolutely.

Operating hour counter
The Novotron has three operating hour counters. If only "Timer" lights up, the first operating hour counter
is shown. The operating hour counter records the time the mains switch is turned on, irrespective of the
time the temperature and shaker speed controls are operating.
After at the latest 10s the display changes to the next operating hour counter. Now "Timer" and "RPM"
light up - this operating hour counter records the shaking length.
After some time, the display changes to "Timer" and "°C". This operating hour counter records how long
the temperature is regulated (time the ventilator runs).
The operating hours are shown in the display when the SET key and the MODE key are pressed
together. The display shows:
XXX
XX.X
=
=
Hours
Hours x 1'000
The decimal point in the hours value is exclusively to make this distinction and has no other function.
12.
Spare parts
If your shaker suddenly develops any defects please contact your dealer or nearest INFORS
representative. For reasons of confidentiality, and because of the shaker's complex design, INFORS only

Disposal
The plastic components of the NOVOTRON are made without elements which contain CFC's. It consists
of polyurethane, which makes normal disposal possible.
Also, the different elements such as the incubation chamber, blowers, flywheel etc. can be disposed of in
the same way.
Please take care over the correct handling of the chiller coolant (refrigerant R 134) on disposal of the
refrigeration system. The whole chiller, or at least all the coolant fluids, have to be handed over to official
disposal centres.
