Innova 3100  M1231-0050 Operating manual

2.1 General Description

The Innova 3100 is a shaker that incorporates a triple eccentric counterbalanced drive to provide horizontal plane rotary motion in a ½ inch (12.7 mm) circular orbit. A Proportional/Integral (PI) microprocessor controller with instantaneous digital feedback controls the speed over a range of 25-400 RPM. It also provides temperature control over a range of 5°C above ambient to 80°C. For lower temperatures an optional water bath cooling coil is available.

The shaker may be operated either continuously or in a timed mode via a programmable timer for shaking periods of 0.1 hour to 99.9 hours.

The Innova 3100 is equipped with audible and visible alarms which are activated when an alarm condition exists as follows:

• The end of a timed run

• Deviations of shaking speed or temperature outside of tolerance limits

• Low water level

• Water overflow

A wide variety of platforms can be used with the Innova 3100. Dedicated platforms are available for a variety of flask sizes. A Universal platform and test tube racks are also available. (See Chapter 7 for accessories.)

The Innova 3100 has a built-in water level control system which is infinitely adjustable over a wide range. To compensate for evaporation, water is automatically replenished to the preset level.

Additionally, the Innova 3100 has analog outputs for a chart recorder that will record speed and/or temperature. See Chapter 5 for recorder adaptation.

See Figures 1 and 2 below for the front and rear views of the Innova 3100.

2.2 Universal Power Capability

A voltage selector switch is used to select the appropriate voltage. This universal system adapts to worldwide power requirements. Voltage has been set prior to shipment. Innova shakers are available in 100V, 120V, 220V and 240V versions, and accommodate both 50 and 60 Hz frequencies.

WARNING!

It is critical that you check the voltage settings before you plug the unit into a power source. See S ection 3.2.

2.3 Control Panel

The control panel (see Figure 3 below) is located on the front of the instrument. It serves as the operator interface. The keypad has four keys marked START/STOP, ∆, ∇, and SELECT. A three-digit LED display provides numeric values as well as some letter codes. There are four function indicators and four status indicator lights on the control panel as well. A general description of the display, user interface keys and indicators follows.

For operation of the control panel, see Chapter 4.

2.3.1 LED Display

The Innova control panel has a 3-digit LED display. During normal shaker operation, the display will indicate:

• Shaker status (on/off)

• Shaking speed

• Setpoints

• Hours remaining (timed run)

• Measured temperature

• Low water level

Innova 3100  M1231-0050 Operating manual

•

∆, ∇

Figure 3: Control Panel

2.3.2 User Interface Keys

• START/STOP

This key is used to start or stop the shaking motion. It will also activate or stop the timer when a timed run is desired.

• SELECT

This key is used to change the displayed parameter.

These keys are used to adjust the setpoint of a displayed parameter up or down. They also allow the user to enter the SET mode for setpoint changes.

2.3.3 Status Indicator Lights

There are four status indicator lights, located to the left of the LED display:

• MAINT

Lights to indicate that 10,000 hours have elapsed since the unit was last serviced. Accumulated running time is internally monitored and may be displayed as a guideline.

• SET

Indicates that the shaker is in the SET mode, that setpoints are being displayed and that they can be altered.

• TIME

Indicates that the timer is in operation. Innova shakers can be programmed to run for a preset time from 0.1 hour to 99.9 hours. The timer can be disengaged to reset without stopping an ongoing run.

• MUTE

Indicates the status of the audible alarm. When the MUTE indicator is illuminated the audible alarm device is disabled.

2.3.4 Function Indicator Lights

There are four function indicator lights, located to the right of the LED display. They indicate the current parameter being displayed:

• RPM Revolutions per minute

• HRS Time remaining

• °C Current Temperature

• * Low Water Level

2.4 Platform Assemblies

The Innova 3100 can be used with a wide variety of NBS 12 inch x 16.5 inch platforms which will accept a variety of clamps for flasks and test tubes. Additionally, a subplatform is available to adapt half platforms for flasks and test tubes used on the NBS Model G86 Aqua Therm Water Bath Shaker.

2.5 Cooling Coil Option

The Innova 3100 can be ordered with a cooling coil factory-installed. The cooling coil provides the ability to operate at temperatures below ambient.

2.6 Accessories & Options

The following accessories are available for use with your Innova 3100:

• Gable Cover (plexiglass or stainless steel).

• Portable cart or space saving dolly.

Innova 3100  M1231-0050 Operating manual

For operation below ambient temperature, the following kits are available for retrofit (by an NBS-authorized service technician only):

• Cooling coil kit.

• Coolant Circulating System.

2.7 Triple Eccentric Drive

The Triple Eccentric Drive (see Figure 4 below) used in the Innova Shakers employs the same proven technology which has driven New Brunswick Scientific’s shakers for over 30 years.

This drive mechanism utilizes a counterweight system to stabilize the rotary motion produced during operation. When the workload moves in one direction, opposing forces are generated to stabilize the shaker. This action will help eliminate the problem of “walking” which may occur with less precisely balanced instruments. Vibration is minimized and the life of the unit is extended.

Figure 4: Counterbalanced Drive Mechanism

2.8 Bearings

Innova shakers employ shielded lubricated ball bearings of the highest quality. Shielded bearings minimize the generation of airborne particulates which may be disadvantageous in clean rooms or controlled environment areas. These bearings require no maintenance.

2.9 Motor

The Innova 3100 Shaker uses a 3-phase brushless ball bearing DC motor. This low profile motor provides high torque along with quiet, efficient operation and low maintenance. This motor has a rating of 1/15 horsepower.

2.10 Electronic Boards

The main control board for the Innova shaker has the following functions:

• Non-volatile memory for storage of key parameters during power interruption;

• Speed sensing, electronic commutation, and power control for the brushless DC

drive motor;

• Maintains an elapsed running time clock;

• Contains firmware for shaker control as well as recognition of an expansion

connector for option modules;

• Provides an operator interface via displays, audible alarm, and connection to the

keypad module (keypad buttons and display graphics).

The Temperature Control module for the Innova shaker has the following functions:

• Control of analog power supplies;

• Rectification and regulation for analog power supplies;

• Provides signal conditioning circuitry and A/D conversion for the RTD-based

temperature measurement;

• Provides remote monitoring capabilities by supplying analog output for speed and

temperature which are compatible with chart recorders and analog data acquisition system;

• Controls the heater.

Innova 3100  M1231-0050 Operating manual
