PREFACE
Welcome to the Operator’s Manual for Conviron’s CMP6050 Control System. This Manual
has been developed to assist with the setup and daily operation of the CMP6050. The
Manual is provided to all clients who have purchased a chamber(s) containing the new
CMP6050 control system.
The Manual has been designed to provide sufcient detail for the majority of chamber
congurations, including a structured format that provides step-by-step instructions. Clients will
nd sufcient detail for a typical installation including gures, diagrams, and graphics to operate
the chamber without issue. However, given that many installations are specic to each facility
and that facilities may have unique requirements, additional information or assistance from
Conviron may be required. In such cases, contact information is provided on the following page.
The CMP6050 has a security feature to manage Users' level of access. This feature requires
all Users to be set-up with the appropriate access as determined by the facility manager/
security administrator (up to 3 User ID passwords can be assigned). Once this is completed
(and provided Security is turned on), Users are required to login. This is to ensure that Program
modications are made by authorized personnel only. The Administrator can override all Users
and can access all programming functionality with the exception of features set at the factory.
The CMP6050 offers three password-protected security levels:
• Users (Access Level 1)
• Administrators (Access Level 2)
• Factory (Access Level 3)
Security Access levels associated with various features are identied throughout this manual and
listed in Section 7.0. The CMP6050 is shipped with security features turned Off. This enables
any User to start the chamber and become familiar with the chamber controls without having
to enter a password.
It is recommend that a security Administrator be assigned to administer User
login authority and that security features be added as soon as possible.
This equipment is only to be used by authorized personnel – that is, personnel who have been
trained on the proper use of the equipment and who have read this manual.
The manual incorporates CMP6050 software version 4.06.

1.0 PRECAUTIONS
The following symbols are used throughout this manual to draw your attention to important warnings,
guidelines and product information. Please take note of their respective meanings.
Hazard Warning Important Information
Dangerous Electrical Current Please Note
Hot Surface Grounding Mark
Slippery Surface Caution, Moving Parts
Please note the following Hazard warnings before operating this equipment:
• This equipment is only to be operated and maintained by authorized personnel - that is,
personnel who have been trained on the proper operation and/or maintenance of the
equipment and who have read this manual.
• If in doubt about safe operation and/or maintenance of the equipment, contact the
responsible party immediately.
• Prior to operating, users should conduct a visual inspection of the equipment and surrounding
area by walking around the unit and checking both inside and outside to ensure no debris or
obstacles are present that could pose a safety hazard. If operators see a potential hazard (e.g.
water accumulating on the oor which could be slippery, an obstruction that would prevent
the door from opening/closing properly) they should take appropriate steps such as alerting
service personnel.
• Before starting, the operator should ensure that all electrical boxes are in the closed
position and that no one is present in the chamber – either servicing or working
within/on the unit.
• Ensure that no one is using or could activate the room remotely during operation or
maintenance activities.
• Avoid water coming in contact with the electrical components, as it presents a risk of
water damage to both high and low voltage electrical components. If you have any
doubt of safe watering practices, contact Conviron.
• When a Schedule is not running, Alarms are disabled! No one other than a single,
designated on-site service technician should be operating the chamber. Altering
output parameters to troubleshoot a chamber, while others are handling mechanical or
electrical systems within the chamber, COULD BE HAZARDOUS AND MAY RESULT IN
PERSONAL INJURY. As such, manipulation of output parameters must be performed
with either a qualied service technician present or via phone support with Conviron’s
Technical Services group.

CHAPTER 1 | PRECAUTIONS
• Qualied trades-people such as electricians, plumbers, refrigeration mechanics, etc.
should perform all work as required by local codes and regulations.
• Central Management™ (CM) is an optional feature. If CM is being used it becomes
inextricably linked to the use of the Controller and therefore, both the Central
Management manual and the Controller Operators Manual must be read and
understood in their entirety prior to operation.
• Working with high voltage will be required when installing this equipment. Do NOT
attempt this work unless you have the appropriate knowledge and experience. Take
appropriate safety precautions and ensure that the building power supply to the
chamber is off prior to installation.
• The main terminal in the control panel has live voltage unless the external breaker is
OFF. Use extreme caution when working in the control panel to prevent injury.
• Water that could come in contact with the electrical components presents a high
voltage hazard. Avoid these conditions. If you have any doubt of safe watering
practices, contact Conviron.
• Controller may come equipped with an optional Uninterrupted Power Supply (UPS)
such that power will remain live for a period of time even if the power supply is turned
OFF. Use extreme caution when working on the control panel to prevent injury. If you
have any doubts as to whether your unit comes equipped with a UPS, contact Conviron.
• Inside the control panel is an independent temperature shut-off device called the
ir33. This ir33 acts as a secondary fail-safe protector that shuts off the chamber if its
temperature limits are exceeded. The ir33 is set by Conviron and is factory protected
(requires Access Level 3). The factory default setting for the ir33 temperature limit is
ten degrees beyond the chamber operating range. The standard operating range of a
chamber is +4˚C to +45˚C while the standard ir33 shut down settings are -6˚C to +55˚C
depending on the size of the chamber, size of the compressor and other factors. Always
verify, when changing the (Alarm) Temperature within the 6050 setup, that the limits
are still within the minimum and maximum operating limits for the Chamber. This will
ensure that the ir33 only triggers in the event that the actual temperature exceeds the
Chamber's minimum or maximum temperature limit by 10 degrees. It will also ensure
that the ir33 does not trigger before a high or low temperature tracking alarm. The ir33
is located inside the control panel where there is live high voltage. Contact Conviron
Client Services for more information or help if necessary.
• Surfaces and lighting may become hot during operation. Always take appropriate
precautions and do not operate if users will remain inside the chamber for more
than a few minutes unless adequate shielding or other safety precautions are taken.
NOTE: HID lamps can cause serious skin burn and eye inammation from short-wave
ultraviolet radiation if the lamp envelope is punctured or broken.
• Operators should note that water may accumulate on the oor which could be slippery
and pose a safety hazard. Always ensure oors remain dry and wear non-slip footwear.

2.0 INTRODUCTION TO THE CMP6050 CONTROL SYSTEM
2.1 An Overview of the CMP6050
The CMP6050 is congured at the factory and offers a wide array of set-up, control and alarm
features to ne tune the conguration on site. The scalability of the CMP6050 accommodates
additional Input/Output ports if necessary. This exibility enables users to add sensors allowing
the CMP6050 to adapt when changing or modifying experiments.
The CMP6050 control system consists of three primary components:
• Controller
• Display
• Control system Software.
2.1.1 Controller
The Controller (Figure 2-1: CMP6050 Controller) is mounted inside the chamber’s control
cabinet and comprises the actual Programmable Logic Controller (PLC). The controller’s job is
to monitor the control parameters and adjust the outputs to coincide with the User’s programs/
schedule. The controller also noties the User with alarms when parameters, for any number of
reasons, deviate outside of specied limits.
Figure 2-1: CMP6050 Controller

CHAPTER 2 | INTRODUCTION TO THE CMP6050 CONTROL SYSTEM
2.1.2 Display
The Display (Figure 2-2) provides the interface to the control system using a LCD (Liquid Crystal
Display) touch screen and push-button keys. There are also three LED indicator lights on the
Display which are used for notifying the User of various conditions.
The touch-screen Display provides access to the following functions:
• Programming and Scheduling
• Alarm
• Security
• Logging
• Graphing
• Service
Information on the touch screen is easy to read because the screen is backlit. Icons are touch-
activated and initiate a controller action when they are tapped (or activated with the stylus).
2.1.3 Software
The controller Software is installed into the controller by Conviron prior to shipping and
facilitates interaction with, and control of, the chamber. Like other software products, CMP6050
software carries a version number. Accessing the installed software version number for the
controller is described in Figure 3-2, under the Information Icon.

CHAPTER 2 | CMP6050 Operator’s Manual
2.2 General Specications
CMP6050 control system is a robust industrial grade PLC control system designed
for a wide range of controlled environment applications:
• The display uses a 6-inch touch-screen LCD
• Alarms are color-coded directly on the screen making alarm conditions quick to identify
and resolve
• Temperature set-point changes can be set in either STEP or global RAMP (gRAMP)
mode. Humidity, light, and CO2set-point changes can be set in STEP mode only
• A default Status screen amalgamates set points and actual conditions into a single, concise
dashboard for easy viewing and improved chamber management.
2.3 Local Control Interface - Programming and Scheduling
• Touch-screen LCD
• Real-time clock programming of control variables
• Can store a maximum of 16 real-time, user-entered programs
• Can store up to 48 timelines per program (with one minute resolution)
• Programs are then entered into the schedule (a sequence of up to 8 program entries) to
create a single day, multi day, seasonal or infinite schedule
• Temperature transitions set as either STEP or gRAMP mode
• Humidity, light and CO2transitions are set on STEP mode.
2.4 Data Logging and Management
Log data for the CMP6050 can be viewed two ways: locally at the control system interface, or
remotely via a network-connected PC.
2.4.1 Local Data
• The data available at the local control interface includes main chamber variables –
temperature, humidity, lighting, and CO2(if applicable).
• Parameters are all logged automatically by the controller every 18 seconds.
• Data can be accessed with up to five days of history.
• Trend graphs can be viewed directly on the local control interface for both set-point and
actual values (only inputs).
• Zoom and Pan functions provide additional visualization tools allowing the User to precisely
and accurately view and assess the data.

March 2015 |253652R06
2-4
CHAPTER 2 | INTRODUCTION TO THE CMP6050 CONTROL SYSTEM
2.4.2 Remote Data
• The data available remotely is more substantial and includes every input and output
parameter being monitored and controlled.
• Data is logged automatically by the controller every 18 seconds regardless of the number of
parameters. This provides unprecedented data resolution for the User while it also benefits
service personnel.
• Log data is accessed in several ways:
a. A network-connected PC
b. An internet-enabled PC
c. Conviron’s Central Management system (Optional)
2.5 Alarms
• Audible and color-coded visual alarms are provided.
• User-settable absolute alarms for all controlled processes.
• User-settable process tracking alarms for temperature (in gRAMP or vRAMP mode) are
available for the User to determine how tightly to monitor the experiment.
• User-settable process for disabling a controlled process, and thus alarms, at any time
while a program is running.
2.6 Security
CMP6050 security is divided into three password-protected levels:
Users Access Level 1
Administrators Access Level 2
Factory Access Level 3
2.7 Start-up Delay
At start-up, CMP6050 controllers randomly select delay times between 0 and 59 seconds (by
default) to reduce start-up loads after a power failure. This delay time can also be programmed
by the User (reference Section 8-3: (Chamber) Start-up Delay).

March 2015 |253652R06 2-5
CHAPTER 2 | CMP6050 Operator’s Manual
2.8 Communications
Ethernet connectivity is delivered with every controller. The controller is shipped
communications-ready and requires set-up at the facility by a network administrator or other
qualified personnel. (Note: Connectivity is optional on the Adaptis product family).
2.9 Auxiliary Contacts
The controller has 13 auxilliary hi/low digital outputs that can be used to for basic control of
additional equipment.
2.10 Central Alarm Contact
A normally closed dry contact energized by the controller alarm output for connection to a
Building Management System (BMS) or optional auto dialer. When an alarm condition occurs,
the normally closed contact opens, interrupting the circuit from the BMS (or other system) to
indicate an alarm. Only triggered by shut-down alarms (see Section 6.0 Alarm Screen).
2.11 Optional Accessories
AUX: Programmable Output provides an auxiliary switch, terminated in the control panel, for
timed control of automatic watering, nutrient dosing, etc. Auxiliary outputs can be binary (on/off)
and/or time based (01-9999 seconds).
SEN: Thermistor temperature sensors available in 10ft (3m), 30ft (10m) and 50ft (15m) lengths.
Consult Conviron for more information.
ADIAL: An automatic telephone dialing system (autodialer) to notify the User of a chamber
alarm. Note that this requires Conviron’s Central Management™ system, which is sold as a
separate product. Consult Conviron for more information.
VAR: There are two process control modes which govern the way in which chamber
processes (temperature, humidity, light, CO2) transition between set points. The default
process control mode set at the factory – called BASIC – is to control temperature in STEP or
global ramp (gRAMP) mode while all other processes are controlled in STEP mode. Clients
do have the option to independently control chamber processes (humidity, light and CO2) in
either STEP or variable ramp (vRAMP) mode – called VAR.

CHAPTER 2 | INTRODUCTION TO THE CMP6050 CONTROL SYSTEM
2.12 Process Control Modes: BASIC and VAR
Programs are lists of timelines, with each timeline specifying target set points for all
controlled processes (temperature, light, humidity, and CO2, if equipped). There are three
different ways the chamber can transition between target set points: step (STEP), global
ramp (gRAMP) and variable ramp (vRAMP). The control mode (BASIC or VAR) determines
which of these transition modes (step, gRAMP, vRAMP) are available to the User (Figure 2-3:
Process Control Modes, Figure 2-4: Process Transition Modes). Further information about
setting transition modes can be found in Section 5.4.4.1 Process Transition Mode – RAMP

2.12.1 STEP Transition
• STEP transitions are available for all temperature, humidity, light, and CO2in both
BASIC and VAR control modes. In this transition mode, the chamber increases or
decreases the process as fast as the chamber is mechanically capable (see Figure 2-6).

CHAPTER 2 | INTRODUCTION TO THE CMP6050 CONTROL SYSTEM
2.12.2 Global Ramp Transition (gRAMP):
• gRAMP transitions are only available for temperature (see Figure 2-3). In this mode
the chamber increases or decreases temperature at a defined rate selected by the
operator ([x]min/[1°C]), referred to as the global ramp rate (see Figure 2-7).
• Only one global ramp rate is possible at any time. This rate may be changed by
the User, but all temperature transitions in all programs in the schedule will occur
at this global rate. The global ramp rate is set by the operator in the Schedule -->
Preferences screen (see Section 5.4.4 Preferences)
• The default ramp rate set at the factory is 4min/°C, which is the maximum (fastest)
global ramp rate possible.
• When a timeline specifies a new target set point, temperature begins to change
until it reaches that target set point temperature, encounters another timeline with a
different target set point temperature, or the program ends.
• In order to ensure the temperature achieves its target set point at a specific time,
the operator must calculate the amount of time required for the temperature to
reach that target set point from its previous set point based on the global ramp rate.
In the example below, the transition from 10°C to 20°C at 4min/°C requires:
(magnitude of change in process set point values) x (ramp rate in mins per degree)
= (20 - 10) * (4) = 40min. This means that to arrive at 20°C by 9:00, the time line
specifying the 20°C target set point value must occur at 8:20.

CHAPTER 2 | CMP6050 Operator’s Manual
2.12.3 Variable Ramp Transition (vRAMP):
• vRAMP transitions are available for temperature, humidity, light, and CO2 processes
(see Figure 2-3). In this mode the chamber changes the process at a linear rate
between timeline target set points. This allows the User to program ramp transitions
with many different ramp rates in the same program (see Figure 2-8).
• The ramp rate is determined automatically by the controller based on the amount of
time between timelines and the magnitude of change between process set points
specified by those timelines, eliminating the need for the User to set the ramp rate.
• Each transition requires two timelines: One to specify the start of the transition,
and one to specify the end. When the controller reaches the last timeline in the
program, it will maintain set point conditions specified by that timeline until the
program ends at midnight.
• As with gRAMP, the maximum (fastest) variable ramp rate = 4min/°C. If the User
programs timelines with target set points that exceed this maximum rate, the
controller will default to the maximum ramp rate of 4min/°C for those time lines.

CHAPTER 2 | INTRODUCTION TO THE CMP6050 CONTROL SYSTEM
2.12.4 Disable
When a process is set to Disable in control mode VAR, the controller will disable control of
the process and ignore all set points for that process in all programs in the schedule. This
does not affect the values entered in any saved programs, and the process will still trigger
corresponding alarms.
For example: if Humidity is set to Disable, and the low limit alarm had previously been set
to 20% RH, humiditiy values below that limit will still trigger a warning alarm (see Section 6.0
Alarm Screen for more information on alarms).
