1.1 General Description
The Innova 4900 microprocessor-controlled Multiple Shaker Environmental Chamber
will provide you with reliable and maintenance-free operation that is characteristic of
all NBS shakers. The Innova 4900 is among the newest generation of NBS shakers
and incorporates a variety of state-of-the-art components and features to permit the
precision operation necessary for your exacting scientific experiments.
The Innova 4900 Environmental Chamber can accommodate up to four shakers while
maintaining precise temperature and humidity control. Shaking speeds are adjustable
from 25 to 400 RPM with 1-inch stroke machines and from 25 to 300 RPM with 2-
inch stroke machines.
A microprocessor-based environmental control module provides digital
proportional/integral (P/I) control of temperature and humidity. An integral
refrigeration system allows precise temperature control at or below ambient
temperatures. An electric flash vaporizer controls the humidity in the chamber up to
90% RH. The chamber dimensions are 30 inches wide x 66 inches high x 22 inches
deep (76 x 168 x 56 cm).
Optional grow lamp manifolds are available for use in photosynthetic investigations.
The lamp control system allows the lamps to be programmed to operate at
predetermined times via a 7-day, 24-hour electronic timer. The timer may also be
used to switch the chamber to an alternate temperature setpoint at preprogrammed
intervals.
The Innova 4900 is designed so that all normally required services and repairs can be
performed from the front of the unit. This allows multiple units to be installed side by
side for maximum space utilization.
The environmental control module also acts as a master communications module,
transferring data to and from the individual shaker controllers. It can interface to an
analog chart recorder to provide a record of the chamber temperature, humidity and
the speed of each shaker.
The Innova 4900 is equipped with a heated double-pane glass door to minimize
condensation while allowing visibility of the chamber interior.

14
New Brunswick Scientific User’s Guide
The Innova 4900 also has an RS-422 serial communications port and is compatible
with the NBS AFS BioCommand supervisory software package. This provides the
ultimate in remote monitoring command, and data collection capabilities.
The Innova 4900 chamber has provisions for installing various combinations of
shakers and lamp manifolds up to a combined total of four units (no more than two
may be lamp manifolds). Mounting positions are adjustable to provide maximum
flexibility in accommodating various sizes of flasks. For details on the installation
and operation of shakers and lamp manifolds, consult the appropriate manual.

1.2 Input Power Requirements
The Innova 4900 may be operated from a 208-volt power source at 60 Hz, or a 220- or
240-volt power source at 50 or 60 Hz. Input voltage and frequency selection require
the placing of three harness wires in the appropriate terminal blocks on the main
electrical panel: this should be done only by qualified service personnel.
WARNING!
It is critical to check the voltage and frequency settings before
applying power to the unit.
Confirm that the factory settings marked on the Electrical
Specifications Plate match your power source. If they do not,
see Section 5.2, Changing Voltages.

1.3 Environmental Control Panel
The environmental control panel is located on the righthand side of the Innova 4900
unit and is always the uppermost control panel (see Figure 1).
As illustrated in Figure 3 below, the keypad has four keys marked START/STOP, S,
Tand SELECT. A three-digit LED display provides numeric values as well as some
letter codes. There are also four function indicator lights and four status indicator
lights on the control panel. A general description of the display, user interface keys,
and indicators follows. For operation of the control panel, see Section 3, Operation.

1.3.2 Keypad
The environmental control panel keypad has four user interface keys (see
Figure 3): Table 1: User Interface Keys
START
STOP Activates and deactivates the audible alarm system. It
is also used to display the RS-422 multidrop address
of the Innova 4900 system.
S
TAdjusts, upward or downward, the setpoint of a
controlled parameter
SELECT Changes the displayed parameter.
1.3.3 Status Indicator Lights
There are four status indicator lights (see Figure 3):
Table 2: Status Indicators
MAINT Indicates that 10,000 hours have elapsed since the
unit’s last service.
SET Indicates that the unit is in SET mode, which means
that setpoints are being displayed and may be altered.
COMM Indicates that the unit is receiving and responding to
computer control.
MUTE Indicates the status of the audible alarm: when this
light is on, the audible alarm is disabled.
1.3.4 Function Indicator Lights
There are four function indicator lights (see Figure 3); one illuminates to
indicate the parameter being displayed:

1.4 Refrigeration System
The Innova 4900 is equipped with a 1/2 HP refrigeration system. The condensing unit
is hermetically sealed and the evaporating temperature is closely regulated to prevent
coil icing.
A hot gas bypass system is employed along with an electric heater to precisely control
the chamber temperature.
The entire refrigeration and heating system is managed by the microprocessor-based
digital control system in response to the temperature setpoint and ambient temperature
conditions.
1.5 Humidifier System
The Innova 4900 uses a solid-state integrated circuit relative humidity sensor for quick
response and accurate humidity measurement. The microprocessor controller
automatically compensates for temperature variations.
The humidifier element is an electrically heated flash vaporizer. Water is metered into
the vaporizer via a small orifice solenoid valve. The solenoid valve is controlled by
the digital control system to maintain the desired humidity level inside the chamber.
NOTE:
To prevent mineral build-up in the vaporizer and the chamber, only
de-ionized water should be supplied to the Innova 4900.
1.6 Excess Vibration Sensor
The Innova 4900 is equipped with a vibration sensor that detects excess cabinet
movement due to out-of-balance shakers. If severe vibration occurs, the Innova 4900
automatically shuts off any shakers that are running. The operator must resolve the
problem before restarting them.
1.7 Electronic Boards
The master control board for the Innova 4900 has the following functions:
 Non-volatile memory for storage of key parameters during power interruption;
 Maintains an elapsed running time clock;
 Internal communication with installed shakers;

19
M1197-0053 Innova 4900 Environmental Chamber User’s Guide
 Contains the firmware for temperature and relative humidity control and for
chart recorder and computer interface;
 Provides an operator interface via displays, audible alarm, and connection to
