INTRODUCTION
The CARON 6010 & 6030 series Environmenta Test Chambers provide mu tip e capabi ities to
create repeatab e environmenta conditions for numerous app ications inc uding:
• Product she f ife
• Stabi ity and package testing
• Light exposure and temperature eva uation studies
• E ectronic component burn-in
• TAPPI testing
• Photostabi ity
• P ant growth
• Insect rearing
These chambers uti ize environmenta y friend y HFC refrigerant and CFC-Free insu ation, and is
designed to meet NEC, UL and CSA standards for safety and performance.
Contro ing the chamber temperature requires the abi ity to heat and coo . Heating of the chamber
is achieved by duct heaters, and coo ing is achieved by a direct expansion/vapor compression
refrigeration heat exchanger mounted in the duct, combined with horizonta airf ow pattern which
creates better air uniformity, and temperature contro .
A bi-moda contro er (sing e input - dua output) is necessary for proper contro of the system that
can drive the process variab e in either direction. The refrigeration system uses a sing e
condensing unit that wi a ow independent coo ing and dehumidification. This insures continuous,
safe and re iab e operation of the compressor even when no coo ing is required. This a so
prevents the compressor from rapid cyc ing “on” and “off” which shortens the compressor ife.

CONTROLLERS
The temperature contro system is comprised of a sing e channe , dua output contro er. On/off
outputs are used to drive heaters and coo ing so enoids. An additiona contro er is used to contro
the humidity (if that option is ordered). Both contro ers are configured and tested at the factory to
ensure proper performance.
Contro er operating procedures and factory defau t settings are isted in the Appendix. Defau t is
temperature disp ay in ºC. For ºF, consu t factory for detai s. In addition, see the separate
contro er manua for more detai s on contro er operation, menus and avai ab e settings.
Due to individua circumstances, it maybe beneficia to modify the defau t settings to best suit an
app ications. Examp es inc ude a arm and communication settings.
NOTE: On power up, the temperature and humidity contro ers a ow the system one minute to
stabi ize prior to turning on outputs. Therefore it is norma for the unit not to turn on heating or
coo ing, or humidify for a fu minute on power up regard ess of set-points and cabinet conditions.
TEMPERATURE DEVIATION ALARM
A units are equipped with an a arm system that constant y monitors temperature to ensure the
user is notified if the cabinet goes into an a arm condition. Notification occurs via a RED indicator
LED and an audib e a arm. Temperature a arms wi occur once the a arm condition has been
present for 15 minutes. This de ay is in p ace to avoid nuisance a arms associated with door
openings.
Examp e of Deviation va ue:
Set point = 30 ° C
A arm high = 5 ° C
A arm ow = 3 ° C
∴
High A arm = 35
°
C and Low A arm = 27
°
C
NOTE: When powering up the chamber, if the actua interior chamber temperature varies from
the setpoint, immediate y set the deviation amount to a arge enough margin in order to a ow the
chamber to reach the temperature setpoint. If the deviation amount is too sma the a arm wi
sound unti the chamber is within the min / max deviation range. The temperature deviation a arm
is preset to 50°C above or be ow set point.

6010 & 6030
Humidity System
A bi-moda humidification system a ows for independent humidification and dehumidification. This
design provides contro over both the humidity injection system and the dehumidification system.
This system permits the chamber to respond faster as we as contro ing the chamber more
efficient y at a constant re ative humidity.
The Humidity Injection System uti izes atomizers to inject moisture into the chamber to achieve
humidity eve s of 98% RH. An extended ow end humidity eve of 20% RH is attainab e due to
the configuration of the refrigeration system ( imited by a minimum 4
°
C dew point). The atomizer
system is preferred over the boi er type system, since it wi not add heat to the chamber. The
added heat causes the system to work harder to maintain temperatures, especia y at ower eve s.

HEATLESS DRYER PACKAGE
The Heat ess Dryer Package is designed to extend the operationa imits of CARON’s Series 6000
Environmenta Test Chamber to its minimum humidity contro point of 2% RH and improve the
dehumidification rate of the chamber. This is accomp ished by “purging” the chamber of its moist
air. The Dryer Package uti izes 90 to 100 PSI compressed air to operate.
A coa escent fi ter (with automatic drain) wi remove sma amounts of incoming moisture.
However, partic es of dirt or rust, as we as arge amounts of condensed moisture or oi that may
be in the compressed air ine feeding the dryer must be removed from the air stream before it
enters the dryer.
CARON recommends insta ing a pressure gauge prior to the dryer to air in monitoring system
pressures. The f ow meter shows the f ow rate of dry air entering the chamber. It is adjustab e by
the knob at the bottom of the meter. Maximum performance is obtained at 300 SCFH (or 5 CFM).
Operating the unit above this purge rate may decrease performance!!
On some mode s, a pressure regu ator is insta ed between the tower dryers and g ass f ow meter
to imit the pressure into the f ow meter. The regu ator shou d be set at a maximum of 100psi.
DRYER PACKAGE INSTALLATION
a) Attach the Dryer package to the exterior chamber with the pre-dri ed mounting ho es and
mounting hardware. Be sure to secure each tower.

b) Attach the 3/8” ID c ear tubing to the out et of the f ow meter. Secure tubing with the hose
c amp provided.
c) Connect compressed air (either from house air or other compressed air source) to the fitting
abe ed “air supp y in et”.
NOTE: THE AIR SOURCE MUST BE OIL-FREE AND WATER-FREE AND FILTERED TO 10
MICRONS MINIMUM.
d) P ug in the air regu ating so enoid ine cord into the matching receptac e ocated above the
dryer mounting bracket.

TESTING AND ADJUSTMENTS
Connect the cord to the proper receptac e as mentioned above, and turn the humidity power
switch “on”.
Turn on air supp y. Be certain that the air pressure into the in et side of the dryer assemb y is set
at a minimum of 90 PSI and not above a maximum of 100 PSI.
To set the pressure regu ator
1. C ose the air f ow adjustment knob
2. Set the chamber to 0% humidity (fu dehumidification)
3. Adjust the pressure regu ator adjustment knob to 90 psi
To set the air f ow rate

1. Set the f ow meter on the dryer assemb y to approximate y 300 SCFH. Watch the humidity
disp ay to see that the % RH is moving down to the specified setpoint.
A ow sufficient time for the chamber to stabi ize when setting up and making adjustments,
especia y if the chamber has been running with high humidity eve s. Running the chamber at
higher than ambient humidity eve s can cause moisture to co ect in a areas of the chamber
inc uding sensors and other components. This moisture must be removed before actua tests can
proceed at accurate, ower than ambient humidity eve s.
CIRCULAR CHART RECORDER,
The Honeywe DR 4300 Genera Purpose Circu ar Chart Recorder uses re iab e microprocessor
operation to generate dependab e pen drawn ana og traces on preprinted 10-inch (250 mm)
charts.
The two-pen mode (RCDR103) accepts inputs from a temperature sensor and a humidity sensor.
The sing e-pen mode RCDR107 records temperature on y.
temperature sensor is a high y accurate RTD. The humidity sensor is a Vaisa a or equa which
uti izes the Humicap
® sensor to measure re ative humidity. The recorder uses disposab e fiber-tip
ink cartridges for dependab e recording with minimum maintenance. The recorders are housed in
a mo ded case with a g ass windowed, gray gasketed door which protects interna components
whi e a owing easy access to the chart.
Input samp es are taken at a rate of 2 times every 1.3 seconds. Each samp e is amp ified and
then converted to a digita signa which is iso ated and passed to the microprocessor. Ana og and
digita fi ters with fixed time constraints provide input signa smoothing as required. Standard
factory set up for chart speed is 7 day operation. Refer to the Chart Recorder’s User’s Manua to
change the chart speed settings for various chart speeds.
