Section 1: Getting Starte
This section provides the basic information you need to start using the 200. This includes an introduction
to the instrument, a brief hardware description, and instructions for operating in manual mode, running a
program, and checking the chamber status.
•For additional hardware information, see “ 200 basic functions” later in this section.
•For more detailed hardware information, see the CM2 Control Module Technical Manual.
•For information on 200 setup, see Section 2 of this manual.
•For information on programming the 200, see Section of this manual.
•For definitions of many of the terms used in this manual, see the glossary at the end of this manual.
Intro uction to the 3200
The 200 is a microprocessor-based programmer and controller. The programmer function allows you to
program temperature, temperature/humidity, or other types of tests and store them in program memory.
You can use these programs to operate the controller functions of the 200.
Most 200 programmer/controllers are configured for either single-channel operation (temperature only),
or dual-channel operation (temperature and humidity). If your 200 is configured for dual-channel
operation, it can operate as a temperature-only system or as a temperature/humidity system.
•Typically, channel 1 is dedicated to chamber air temperature using a dry bulb thermocouple. Channel
1 operates the chamber’s heating and cooling systems.
•Typically, channel 2 is dedicated to humidity using either a solid-state humidity sensor or a wet bulb
thermocouple. Channel 2 operates the chamber’s humidifying and dehumidifying systems.
•Channel may be configured for product temperature control (PTC). PTC is a heating and cooling
process that controls the process variable based on the product temperature rather than the test
space air temperature. OTE: Product temperature control and humidity cannot be run at the same
time.
Although the 200 can be configured for up to three programmable channels, for ease of use this manual
is based on the more common one- and two-channel configurations. Three-channel operation follows the
same basic principles described in this manual.
The 200 can be programmed and operated locally using the display screen, function keys, and keypad.
The 200 also can be programmed and operated from a host computer. For more information, refer to the
3200 Programmer/Controller Computer Interface Manual.
The controller functions operate the chamber and its attached equipment. Analog and transistor-transistor
logic (TTL) level signals control and monitor the system. The chamber’s conditioning systems, printers,
chart recorders, and solid-state relay devices are operated from the controller signals. Other analog
devices also can be monitored and operated.
Thermocouples can be mounted throughout the operating systems to feed diagnostic information back to
the controller.
Before operating the 200, several setup procedures must be completed. Most of the setup procedures
were performed at Thermotron; however, these procedures may need to be performed again if
requirements change. Refer to Section 2 for setup instructions.

3200 basic functions
The following sections provide brief descriptions of some of the 200 functions.
Control channels
Control channels receive inputs from thermocouples and/or other sensing devices used to monitor the
environmental conditions inside the chamber’s test space. The 200 adjusts its control outputs based on
those inputs.
•Typically, channel 1 uses a thermocouple mounted in the chamber airflow to sense air temperature. Its
outputs control the heating and cooling systems.
•Typically, channel 2 uses a solid-state humidity sensor to monitor chamber humidity. The reading from
the sensor is used together with the reading from the channel 1 thermocouple to calculate chamber
humidity. The channel 2 outputs control the humidity system’s steam generator and dehumidify coil.
•Channel , if available, can sense temperature or linear inputs. These channels commonly are
configured for such options as product temperature control or altitude.
•Channels 5 through 8 can be programmed at the factory as constant control channels. Each channel
can be set at the factory to sense either temperature or linear inputs.
Chamber con itioning system signals
The chamber conditioning signals are used by the controller to operate chamber systems such as heating,
cooling, and humidity. These signals are dedicated to the system and are internally programmed.
•The system, refrigeration, and humidity enable outputs allow their respective systems to turn on.
•The heat and cool outputs control their systems. For example, the channel 1 cool output normally
operates the solenoids that regulate the flow of refrigerant into the chamber’s evaporator coil.
•The auxiliary cool output operates any auxiliary cooling system, such as liquid nitrogen (LN
2
) or carbon
dioxide (CO
2
).
Alarm output signals
The alarm output transistor-transistor logic (TTL) signals indicate when the chamber temperature or
humidity exceeds the programmed limits. Two types of alarms are available for each channel:
•Deviation alarms are activated when the chamber temperature, humidity, or other process variable is
outside the channel’s deviation alarm band. A deviation alarm band restricts how far the process
variable can be from set point. For example, a deviation alarm band of 5°C activates the alarm output
if the chamber temperature is more than 5°C from set point.
Deviation alarms can be set for each manual mode test or program interval. For more information, see
“Running in manual mode” below, or Section later in this manual.
•Process alarms are activated when the chamber temperature, humidity, or other process variable is
outside the process limits. The process alarm settings restrict the high and low limits of a test. A
process alarm stops the programmer/controller. For example, if the high process alarm limit is +125°C,
the alarm is activated if the temperature equals or exceeds +125°C.
Process alarms are a configuration setting that can be adjusted only in setup mode. For more
information, see Section 2 later in this manual.

Auxiliary outputs
Auxiliary outputs provide programmable TTL level outputs. There can be up to two groups of eight
auxiliary outputs. These outputs are programmed on and off during each program interval or during
manual mode operation. These outputs normally are used to program systems on and off. For information
on your chamber’s auxiliary outputs, see your chamber manual.
Running in manual mo e
Manual mode allows you to operate the 200 controller functions. Manual mode operates the chamber
using set point settings. You can enter manual mode when the system is in stop mode.

Running a program
The programmer function operates the 200 using programs. Each program consists of a group of
intervals. In each interval the controller cycles the chamber toward a final temperature and/or other
process variable in a specified amount of time. Once the interval is completed, the 200 either transitions
to the next interval or loops back to an earlier interval.
Once a program is entered into memory it can be run immediately. To create a program, see Section of
this manual.
Program mo e
1. From any screen, press RU . ( OTE: The run
program screen will not appear when in program
edit mode or while a program is running.) The run
program screen will appear:
2. Select option 1 for program 1, interval 1. OTE: To
create a program, see Section of this manual.
. Select a starting interval. Then press the right
arrow key to run the selected program.
OTE: The start interval screen will only appear
when there is more than one interval created.
4. The 200 will enter run program mode and the
chamber status screen will appear:
For more information on the chamber status
screen, see “Chamber Status” later in this section.
5. To suspend the interval at its current settings,
press HOLD. The 200 will enter hold program
mode. From the top level menu, pressing the run
key, while RU P (run program) is displayed in the
