1 1 INTRODUCTION This Manual is intended to provide the user with a complete understanding of how the Innova 3100 Digital Water Bath Shaker operates, its basic components, and information about preventive maintenance and service issues. This manual also includes a complete guide to the installation and operation of the Innova 3100. The manual is divided into three basic sections. Chapters 1-2 provide an overview of the Innova 3100, with all of its features and options.
2 2 2.1 OVERVIEW & FEATURES 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.

4 Figure 2: Rear View 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 Section 3.2.
5 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.
6 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.
7 • 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.
8 For operation below ambient temperature, the following kits are available for retrofit (by an NBS-authorized service technician only): • • 2.7 Cooling coil kit. Coolant Circulating System. 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.
9 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.
10 3 INSTALLATION & SET-UP The Innova 3100 is a versatile instrument that can be operated in a continuous fashion or set for a timed run. The following section describes set up and installation procedures. 3.1 Unpacking & Inspection Upon unpacking the unit, inspect it carefully for any apparent damage which may have occurred during transit. Report any damage to the carrier and to the New Brunswick Service Department (in the USA, call 1-800-631-5417) or to your New Brunswick Service Representative.

17 4.3 Checking a Setpoint To check any setpoint: 1. Press SELECT until the desired indicator is lit. 2. Press either ∆ or ∇ to enter the SET mode, which will display the current setpoint. NOTE: Holding the ∆ or ∇ key down for more than 0.5 second will cause the speed, time or temperature setpoint to change. Should this occur, resetting will be necessary. 4.4 Timed Functions The shaker may be programmed to automatically stop after a preset time period of 0.1 hour to 99.9 hours.
18 4.4.2 Cancelling the Timer To cancel the timer WITHOUT stopping the shaker: 1. Press the SELECT key to light HRS. 2. Set the time by pressing the ∆ or ∇ key until the desired setpoint is displayed (0.1 - 99.9 hours). 3. While the SET LED is lit, press the START/STOP key. The TIME indicator will go out and the display will read “Off”. 4.5 Alarm Functions Innova shakers have an audible alarm which is activated at predetermined times. It may be deactivated in the following way: 1.
19 2. Increase or decrease the setpoint by pressing the ∆ or ∇ key. The temperature alarms, both audible and flashing light, are activated if the temperature is more than 1.0°C higher or lower than the temperature setpoint. The alarm will automatically deactivate as the unit achieves the set temperature. 4.6.2 Deactivating Temperature Control If desired, the temperature control system may be shut off during set-up for special investigations. To deactivate the temperature control system: 1.
20 from flasks, etc., the display temperature may differ from temperatures within the flasks themselves. If you wish to have the temperature display (“Indicated Temperature”) match the temperature at a given point, or match the average of a series of points within the chamber (“Actual Temperature”), proceed as follows: 1. Let the unit equilibrate at or near the desired temperature. Record the Indicated Temperature. 2. Record the Actual Temperature. 3.
21 The SET and MAINT indicators will flash and the accumulated running time will be displayed in hundreds of hours (i.e., “02” equals 200 hours; “102” equals 10,200 hours). This display will continue for 10 seconds and then default to the previous mode readout. 4.9 MAINT Indicator Light After 10,000 hours of operation, the MAINT indicator will light. Preventive maintenance is recommended at this point. The light can be deactivated by NBS service personnel.
22 3. Note the position of the water level and decide whether the desired level is higher or lower. 4. To raise the water level, note the position of the flexible tube graduations (these gradations and markings are for reference only). 5. Lift the tube up and push the excess tubing through the rear wall of the tank. As you raise the control, the solenoid will open and water will fill the bath until the new water level is established. 6.
