The value of "Uar" has a range of 1.0 to 3.0. When"Uar" is 1.0, the door heater is controlled in thesame manner as the other heaters in the incubator.When "Uar" is increased above 1.0, the door heater remains on proportionally longer than the other heaters when the chambers temperature is withinthe proportioning band. For example, when "Uar"is set to 2.0, the door heater will be on twice as longas the other heaters.

The factory setting for "Uar" is 1.0. This valueallows condensation to form on the glass door.Certain applications require that the glass door befree from condensation. Set "Uar" to an initial valueof 1.8. Allow the incubator to stabilize for 24 hrs.Check the condition on the glass door. Increasethe "Uar" value by 0.1 if the condensation is morethan required. Decrease the "Uar" value by 0.1 if the condensation is less than required. Thedetermination of the value for "Uar" is one of trialand error. Allow 24 hours for the incubator tostabilize before adjusting "Uar" to a new value.

12.0 CARE AND CLEANING OF STAINLESS STEEL

NOTETHE FOLLOWING IS A GENERAL WRITE UP INTENDED AS INFORMATION. IT CAN BE USEDON INCUBATORS OR WATER BATHS.

BEFORE USING ANY CLEANING OR DECONTAMINATION METHOD EXCEPT THOSE LISTED IN THE FOLLOWING, USERS SHOULD CHECK WITH PRECISION SCIENTIFIC THAT THE PROPOSEDMETHOD WILL NOT DAMAGE THE EQUIPMENT.

Stainless steel is an alloy of steel with chromiumand nickel which increase the metal's resistanceto rust and corrosion. However, if not properlycared for it can rust and corrode. Exposure to air provides the passivations for clean stainless steel.This exposure produces a thin, durable chromium-oxide film that forms rapidly on the alloy surfaceand gives stainless steel its characteristic"stainless" quality. Exposure of the surface towater and other oxidizing environments alsoproduces this passivating film. However, if freeoxygen is not available due to scale or contaminationbuildup the metal surface may become vulnerableto attack.

Maintaining a neutral pH and frequent cleaning withdetergent and water will give you years of troublefree service for your incubator or water bath. The

following are some guidelines to consider.

Water Distilled water is recommended. Maintain pHbetween 7 and 9 to minimize corrosion of thestainless steel.

De-ionized or reverse-osmosis water may be used.However, if this water is very pure it may be

Procedure1. Verify that setpoint temperature is greater than actual

temperature.

2. Check heaters. A. Disconnect power cord. Remove rear cover.B. Disconnect connectors J6 (bottom left) and J7

(bottom) from power supply board.C. Check heater resistances with an ohmmeter.

Approximate heater resistances (at ambienttemperature) are shown below:

Heater Connections Resistance (in ohms)115V ~

Air J6 Pins 1 & 3 132Water #1 J7 Pins 4 & 5 144Water #2 J7 Pins 5 & 6 144

Au x J7 Pins 7 & 8 576J7 Pins 8 & 9 576

Door J7 Pins 1 & 2 120

D. Replace any heater that does not match theapproximate resistances above.

3. Check TRIAC A. Turn power on.B. Place an AC voltmeter between pins 1 & 3 on wire

side of connector J6 on power supply board.C. Set temperature setpoint below actual chamber

temperature. Voltmeter should read 0 VAC.D. Set temperature setpoint to at least 5C above

actual chamber temperature. Voltmeter shouldread line voltage.

E. If voltmeter does not show correct values in either C or D, replace power supply board.

4. Check Safety Relay A. Turn power on.B. Place an AC voltmeter between chassis ground

and right hand side of R38 on power supply board.C. Set temperature setpoint to at least 5C above

actual chamber temperature.D. Voltmeter should read line voltage. If voltmeter

does not read line voltage, replace power supplyboard.

Problem ProcedureD. There should be an audible "click" from the solenoid

each time the valve is actuated. If not, replacesolenoid.

6. Check CO 2 Sensor

The CO 2 sensor used in this unit is a thermal conductivitythermistor type. Two thermistors are connected in seriesand have a common connection.The approximate in-circuit voltage across each junctionat 37C is 2.1 VDC and at 25C is about 2.5 VDC. Theresistance of the sensor thermistors will vary withtemperature but a general range of resistance, asmeasured between Pins 1 & 2 or between Pins 2 & 3should be between 2K ohms to 4K ohms. Each junctionwill have about 1.5K ohms of resistance at 37C.

1. Actual CO2 percent does not agree with displayed CO

2percent, displayed CO 2 percent drifts or will not injectCO 2, unit will not hold a calibration. May signal possibleproblems with the IRCO 2 sensor.

2. After following the CO 2 calibration procedure Section10.08, if a problem continues the sensor or Power PCBmay be defective. Test the 5 VDC supply at the Power PCB (between TP2 and TP3). After eliminating the power supply as a potential problem check the signal output atthe IRCO 2 sensor. Connect a digital voltmeter NEG leadto jack J1 lead labeled COM (ground). There are 2

COM leads, either lead can be used. Connect the digitalvoltmeter POS lead to jack J1 lead labeled LINEAR(signal output). This linear function gives 0.0 VDC to 1.0VDC output which equates to 0.0% CO 2 to 20.0% CO 2.

3. With the temperature and humidity stable for at least two(2) hours and with a CO 2 setpoint of 0.0% CO 2 and noCO 2 in the chamber, adjust the FINE ZERO potentiometer until the digital voltmeter reads 0.0 VDC+ 0.01 VDC. Enter a CO 2 setpoint between 5.0% CO 2 to 10.0% CO 2 andallow it to stabilize for about ten (10) minutes. Measure theCO 2 with a Fyrite. Multiply the measured CO 2 percentage

by a factor of 0.05 and the value obtained will be theIRPCB output voltage, e.g.5.5% - CO 2 measuredX 0.050.275 VDC IRPCB volts out

Slowly adjust the SPAN potentiometer until the proper outputvoltage is obtained. After completing the above procedure,follow the CO 2 calibration procedure Section 10.06.

ProcedureProblem1. Check magnetic door gasket.

A. Does the gasket fit evenly along the incubator body?There should be no distortions in the gasket that couldcause air to flow between the gasket and the incubator.

B. If distortions exist, remove door liner and reposition or

replace gasket.2. Check glass door gasket.

A. Check for gasket tears or imperfections. Replacegasket, if imperfections found.

B. Verify that the gasket is completely adhered to theincubator chamber. If not, apply RTV Silicone sealant(Dow Corning #732) to gasket and chamber. Allow tocure for 24 hours.

C. Shut and latch the glass door firmly in place. Thegasket/ glass door interface should be completelysealed around the entire perimeter of the glass door.Try to place a business card between the glass door and gasket in any suspect areas. If a business cardcan be placed between the gasket and glass door,replace the gasket or check glass door alignment.

3. Check glass door alignment. A. Check that the two plastic nuts are secured tightly to

the two stainless steel hinges.B. If the door does not appear to be properly aligned,

loosen the four capnuts holding the hinges onto theincubator and re-align the glass door.

C. Repeat step 2C to verify the glass door alignment.

Humidity within the chamber can vary with changing temperature,ambient conditions, and the nature of the sample. Thecondensation, or lack thereof, on the glass door is by no meansa proper way to measure the relative humidity within thechamber, but as a general rule there will be a very slight amountof condensation near the edges of the glass door during normaloperation or sometimes no condensation whatsoever. If all of the glass or greater than half the surface area of the glass iscovered with moisture, this may indicate a door heater problem.

4. Check door heater. A. Turn power off.B. Disconnect connector J7 from the power supply board.C. Check the heater resistance by placing an ohmmeter

between Pins 1 and 2. See section 13.01 for resistancevalues.

If all results by following 13.04 are o.k., see section11.06 for door heater control.

13.04 ExcessiveCondensation


29/42

25

Problem ProcedureNoise inside the incubator chamber, above what would normallybe expected, is usually an indication of fan blade or fan motor trouble. Problems with excessive humidity and poor temperatureuniformity can also signal fan motor or fan blade trouble. The fanblade mounts to the fan motor shaft by friction. The proper rotationof the fan blade, observing the blade from within the chamber, isclockwise. Air is drawn into the fan and is blown out tangent to thefan blade. Buzzing noises can be isolated by checking the fanblade position on the shaft; it may be too close to the plenum, or pushed too far back against the fan motor plate.
