panel. Do and experience. Proceed only with appropriate safety precautions.

Electrostatic hazard: Many electronic components in the control system can be damaged or destroyed by electrostatic discharges (ESD) that you cannot even feel.

You can discharge 5000 volts without feeling it but this voltage is strong enough to destroy many electronic components of the system.

If you handle system components, you MUST wear a grounded wrist strap. The best ground is to the triac heat sink.

In addition: ! Do not let anyone that is not wearing a grounded wrist strap work

on the control panel.

! Do not touch any parts or conductors on the board even when you

are wearing a grounded wrist strap.

! Do not lay paper on static-sensitive parts. ! Ship components to Conviron in anti-static bags. ! Make sure everyone that may work on the control panel is aware

of these procedures.

Failure to follow proper ESD precautions may void the warranty!

Memory-loss hazard: A continuous supply of electricity to the controller is essential to preserve its memory. If its memory is lost, the controller cannot operate and will have to be replaced.

An external battery provides backup for the regular supply of electricity for brief periods when the regular supply is not available.

The battery must be replaced (see Chapter 7: Maintenance and Troubleshooting) at intervals

To promote battery life:

• Keep the controller disconnect switch

switch to turn power for the chamber on and off).

• Keep ambient temperatures within the range of human comfort.

Operation warning:

Always wait at least three (3) minutes after completing any procedure before turning off the controller.

Wait at least 10 seconds before turning the controller on again.

NOT attempt them unless you have appropriate knowledge

NOT exceeding 5 years.

Programming the Controller

There are four major steps to completing a program.

1. Entering timelines

2. Saving the program

3. Chaining the program

4. Running the program

Ramping

Ramping means that the conditions in the chamber change steadily between timelines.

Most control zones in the chamber, such as temperature, relative humidity and CO

operate in ramp mode. For example, in the graphed

program below, the chamber temperature gradually rises from 10º at 0:00 until it reaches the 20º at 9:00.

Note: The CMP4030 does not automatically ramp across midnight because it does not read the next day’s program. Instead, the controller runs the conditions in the last program timeline until midnight.

When one program ends and the next program begins (at midnight), the CMP4030 opens the program file for the new day and reads the first timeline regardless of the program’s time settings.

It is important that programs are well defined so that the controller interprets the settings as intended. To avoid problems,

Sample Program 1: Basic Day/Night program

This program is useful to simulate outdoor conditions.

Note: Program red light spectrum for dawn and dusk by turning on two levels of incandescent lamps and turning off fluorescent lamps.

Temperature

Relative Humidity

Inserting Timelines in a Ramp

• Midnight (0:00) – Temperature in the growth chamber is 18º C

• 7:00 – Temperature has risen to 20º C

• 10:00 – Temperature has risen to 24º C

• 18:00 – Temperature has fallen to 20º and stays constant until 23:59

• Midnight (0:00) – RH is 70%.

• 7:00 – RH has decreased to 65%

• 10:00 – RH has decreased to 55%

• 18:00 – RH has increased to 65% and stays constant until 23:59

Note: Timelines were inserted into this program to control other zones:

• 7:30 – Two levels of fluorescent and incandescent lights come on

• 18:30 – All fluorescent lights shut off, CO

• 19:00 – All incandescent lights shut off, CO

level is set to 500 ppm

level is set to 0 ppm

Note: Some cells have been left blank so that zones that are ramping are not affected when the conditions of other zones adjust.

3-11

Page 30

Chapter 3: Programming

Sample Program 2: Programming in Step Mode

Step programming can be approximated for zones that usually ramp by inserting timelines to keep the conditions constant until one minute before the new condition is required.

For example, to have the temperature in the chamber rise four degrees at 8:00, then fall four degrees at 19:00 (7:00 pm), program as follows.

Note: Programming in step mode is more likely to cause alarms due to conditions temporarily overshooting alarm limit settings for the zone. We recommend that the limits be increased if a step program is used.

Note: The psychrometric chart is a valuable tool when writing a program. To view a copy of the psychrometric chart and for more information on understanding and using the chart, refer to Appendix D.

3. Chaining Programs – Multi-Day Programming

The Chain Program screen provides the facility to create programs that can run with different conditions over multiple days.

Chaining is the process of linking programs together so that they run continuously in sequence. If a program is not chained to itself or to another program, it will stop running at midnight.

• To run the plant growth area under the same program every day,

chain the program to itself.

• To run the plant growth area under different programs each day,

chain two or more programs together. These are called multi-day programs. Multi-day programs are limited in size only by the amount of storage space available in the controller. For additional storage, use a floppy disk drive.

We recommend that each program have 0:00 and 23:59 timelines and that the 23:59 timeline match the 0:00 timeline of the next program in the chain to create a smooth transition from one program to the next.

Alarm Options

Two types of program alarm options are available, Deviation and Tracking.

• Deviation alarms set upper and lower limits that apply to the entire program.

• Tracking alarms are based on the set point at any particular time in the program,

including during ramping. The user sets the minimum and maximum variance from set point.

• Both alarms include a preliminary warning and shutdown settings.

Priority determines what action is taken when an alarm limit is reached, for example raising an alarm message, shutting off the chamber, initiating an auto-dialer.

Alarm Indicators

An Alarm indicator notifies the user that a problem exists.

Two standard Alarm indicators are built into every Conviron growth chamber. In addition to these, there are optional Alarms, which can be built into the chamber.

Standard Alarm Indicators

Optional Alarm Indicators

• An Alarm button

will flash on the Status

toolbar of the controller when there is an active, unacknowledged Alarm. The button will continue to flash until the Alarm is acknowledged.

• A buzzer will sound as the audible equivalent of the flashing Alarm on the CMP4030 controller or as an indication that the ITSO (independent temperature shut-off) has shut off the chamber. For more information on the ITSO, refer to page 8 of this chapter.

• An external Alarm Indicator lamp, which will light up when an Alarm is active.

• A Chamber Alarm Contact (CAC) relay. The CAC is connected to another device or system selected by the user which will indicate an active Alarm.

In most cases, the CAC is connected to an existing internal building security system or an autodialer that will dial a pre-programmed number and leave a message to alert the operator that an Alarm exists.

Chapter 4: Alarm Management

Independent Temperature Shut-Off (ITSO)

Technical Support

The ITSO is a fail-safe protector that shuts the chamber off if its

limits are exceeded. The ITSO relies on its own sensor so that it operates completely independently in case of control system failure.

The factory default settings are 5° beyond the chamber operating range. If settings are changed, they should be no less than 10° outside the range of the programmed high and low temperature settings for the experiment.

The operation of the ITSO is not directly reflected on the Alarm screen of the controller. However, if the ITSO shuts off the chamber, the resulting loss of power to the outputs will trigger a ‘chamber off’ Alarm.

ITSO controls are located inside the control panel where there is live high voltage. Service personnel under the instruction of Conviron Technical Support should set parameters. Contact Conviron Customer Care for more information.

For technical support, contact your local technicians.

1. Touch the Parameter button to cycle through the parameter list. There are two adjustable parameters for the chemical drier operation:

i. Chem drier on delay – sets the delay time before the

drier comes on when %RH is greater than the set limit.

ii. Chem drier off delay – sets the delay time before the

drier shuts off when %RH is less than the set limit.

2. Touch the Set button. The keypad will appear.

3. Enter the chemical drier settings using the keypad.

4. Touch the OK button to confirm the value entered.

5. Touch the Exit button to return to the Options screen.

The Dehumidification On/Off button allows this feature to be turned off when it is not required.

Touch the Dehumidification button to toggle between Dehumidification ON and Dehumidification OFF.

Setting Defrost

• The additive humidity function will still operate if the Dehumidification feature is turned off. If the relative humidity is greater than the set limit, it will eventually settle to ambient condition, adjusted for the temperature variance between ambient and chamber.

• Turning the Dehumidification feature off saves on energy costs and wear on the components.

Defrost parameters should be set by service personnel under the instruction of Conviron Technical Support. Contact Conviron Customer Care for more information.

In addition to the internal memory area, your controller may be equipped with the options of logging to a CCS or a floppy disk.

• If the controllers are networked to a CCS, data is logged to the CCS.

• If the controller has a floppy disk drive, data is logged to the disk in

the B:\ drive.

• To export data to other software, the chamber must be equipped with a floppy disk drive or be connected to a CCS.

• If the chamber is not equipped with a CCS or a floppy disk drive, the data will be logged to the internal memory only and can only be viewed on the Trendgraph screen.

Chapter 7: Maintenance and Troubleshooting

Inspecting and Cleaning Control Panel Components

Inspecting Cooling Fans

Cleaning the Air Intake Filter

Most Conviron chambers are equipped with cooling fans, primarily for the control panel or lighting ballasts.

Regular inspection of the fans is crucial to maintaining reliability and avoiding equipment damage.

Replace non-working fans immediately.

Most Conviron control panels are equipped with a fresh air intake to cool the control panel components. The intake grill and filter prevent dust and other debris from getting inside the control panel.

Clean the air intake filter regularly to ensure adequate cooling of the components.

To clean the filter:

1. Remove the air intake grill mounting screws. Remove the grill and filter from the control panel.

• It is safe to leave the chamber running while the grill

and filter are being cleaned.

2. Wash the filter with a mild soap solution. Rinse with clean water.

3. Dry the air intake filter thoroughly.

Remount the air intake grill and filter using the mounting screws.

Cleaning the BUS and Other Cable Connections

Cables connect the components of the Control system.

The connections may become dirty and may loosen with equipment vibration or thermal expansion.

To avoid control system failure, we recommend that cleaning and reseating these connections be performed as routine maintenance between experiments.

Qualified service personnel using Electrostatic Discharge precautions must perform this work. The procedure is

outlined in the CMP4030 Service Manual.

After shut down on the tracking alarm, the controller will monitor the temperature and will restart the chamber if the temperature is moving towards the set limit. If the temperature is not moving towards the set limit, use one of the following procedures.

Procedure A: If the temperature exceeded the limit by a small margin, widen the setting so the chamber restarts.

If the temperature stabilizes let the chamber run and monitor for problems. If the temperature continues to move away from the set limit, contact

Conviron Customer Care. Procedure B: If the temperature has significantly exceeded the limit, turn the

chamber off and open the doors to let the temperature stabilize to ambient. At ambient temperature, restart the chamber and monitor. (To restart, it will be necessary to either stop and restart the program or cycle the power to the chamber).

If the temperature continues to move away from the set limit for more than a minute, contract Conviron Customer Care.

Appendix D: The Psychrometric Chart

Psychrometrics defines the relationship between air temperature and moisture

content and their effect on relative humidity and dew point.

The psychrometric chart graphically represents the relationship of air temperature and moisture content. Developing an understanding of

psychrometrics and how to read the psychrometric chart will help you,

• understand how to recognize and interpret the influence of ambient conditions on chamber operation and achievable humidity range.

• be aware of the performance capabilities of your chamber.

The psychrometic chart identifies five values.

1. dry bulb temperature – the air temperature read by a shielded sensor or simply, the air’s temperature.

2. wet bulb temperature – a reading based on evaporative cooling effect. To read the wet bulb temperature, cover a sensor using a wick that has been thoroughly wetted and placed in a moving air stream. The cooling

effect of the evaporating water causes a lower temperature compared to the dry bulb air temperature.

3. dew point temperature – the temperature at which condensation first begins, as a mixture of air and water vapor is cooled. Above this temperature, the moisture stays in vapor form in the air.

4. moisture content – the amount of water vapour in the air by weight. This is also referred to as the humidity ratio.

5. relative humidity (percent saturation) – the percentage saturation of the air at a given dry bulb temperature. Relative humidity is a relative

measure, because the moisture-holding capacity of air increases as air is warmed. In practice, relative humidity indicates the moisture level of the air compared to the airs moisture-holding capacity at the same temperature.

App. D - 1

Page 88

Appendix D: The Psychrometric Chart

Using the Psychrometric Chart

If you know the dry bulb temperature of the air and any one of the other values, you can determine the rest of the values.

Refer to the attached psychrometric chart. Using the values that you know, locate their intersection on the chart to determine the other values.

Example 1

Determine the relative humidity.

• the dry bulb temperature is 25°C

• the wet bulb temperature is 20°C

1. Locate the 25° point of the dry bulb temperature on the chart.

2. Locate the 20° point of the wet bulb temperature on the chart.

3. Follow the chart lines until they intersect.

From the intersection, follow the chart lines of the other variables to determine their values. The chart indicates that the relative humidity is 63%, the moisture content is 0.0128 kg/kg and the dew point is 16.5°C.

Example 2

Determine the moisture content.

• the dry bulb temperature is 5°C

• the relative humidity is 60%

1. Locate the 5°point of the dry bulb temperature on the chart.

2. Locate the 60% relative humidity point on the chart.

3. Follow the chart lines until they intersect.

From the intersection, follow the chart lines of the other variables to determine their values. The chart indicates that the moisture content is 0.0032 kg/kg, the

wet bulb temperature is 3.5

°C and the dew point is 2°.

When defining experiment values in the chamber, ensure that the combination of values entered is possible.

By referring to the Psychrometric chart, we can determine for example,

• that the condition of a dry bulb temperature of 30°C with relative humidity of 90% is achievable only with the lights off.

• The combination of a dry bulb temperature of 40°C and 60% relative humidity is not achievable at all.

Understanding your Chamber’s Performance Capabilities

A chamber’s relative humidity operating range is defined by:

• the chamber’s options

• its physical operation

Lower Limit of Operation

• The cooling coil temperature determines the lower limit of operation. The

cooling coil usually runs between 4 – 5 degrees colder than the set air temperature.

• If the lights are on in the chamber, the cooling coil runs between

6 –10 degrees colder than the set air temperature.

• Because the temperature of the cooling coil is slightly lower than the

temperature of the chamber, the dew point is met and condensation occurs. The result is a dehumidification effect.

Note: The coil temperature cannot run below freezing. The condensation will freeze on the coil and result in mechanical failure.

Note: This information is accurate assuming that the chamber is equipped with the additive humidification option and is well sealed.

Lower Limit with Dehumidification

If your chamber is equipped with a dehumidification option, the lower limit of achievable RH is determined by:

1. The type of dehumidification

• A coil type dehumidifier is limited by the same factors that affect the chamber cooling coil. The temperature of the cooling coil is slightly lower than the temperature of the chamber. Most importantly, its temperature cannot go below 0°C or it will freeze.

• A desiccant type or chemical dryer is not affected by temperature but is limited by the amount of moisture that the desiccant can absorb. These types of dryers come in a variety of sizes, so this limitation can be accommodated.

2. Ambient conditions and the amount of ambient air infiltrating the chamber.

• In this case, assume the ambient conditions have a humidifying effect. It is a matter of the dehumidifier’s ability to remove moisture versus the amount of moisture introduced through fresh air.

App.D - 3

Page 90

Appendix D: The Psychrometric Chart

Upper Limit of Operation

The upper limit of operation is determined by the effectiveness of the additive humidity devices (such as spray nozzles), and the cooling coil temperature.

• The warmer the air, the more moisture it can hold. However, there are physical limitations to how much moisture can be injected and absorbed into the air. The temperature of the cooling coil is slightly lower which causes moisture to be condensed out of the air.

• If the fresh air and exhaust ports are open to allow air and CO

exchange

with ambient, the conditions of the ambient air will affect the operational limits of the chamber.

• The RH% of the ambient air is not valid in determining the effect, unless the ambient temperature is the same as the chamber temperature, because this is percentage saturation at a given temperature.

Determining Moisture Content

Refer to the psychrometric chart to determine the moisture content of the ambient air and of the air inside the chamber.

• If the ambient air has lower moisture content than the air inside the chamber, it will create a dehumidifying effect.

• If the ambient air has higher moisture content than the air inside of the chamber, it will create a humidifying effect.

• At normal operating and ambient temperatures, the humidifiers in the chamber can compensate for most dehumidifying effects.

• If the chamber’s operating temperature is low, the additive humidity effect of the ambient air at normal temperatures will create a very high resultant RH inside the chamber.

• If the chamber’s operating temperature is high, the dehumidifying effect of the ambient air at normal temperatures will limit the chamber’s ability to achieve high RH values.

• If the chamber does not have any additive humidification or dehumidification options, the RH % inside the chamber is entirely dependent on the operating temperature of the cooling coil and more importantly, the ambient condition, (as some air infiltration always occurs).
