General Information

This instruction manual encompasses the followingmodels and their specific electrical characteristics.

These ovens utilize a motor driven turbo blower tocirculate heated air throughout the working chamber.In operation, air is drawn into the chamber throughan intake port located at the left side of oven top,passed over the heater bank where it is heated andforced into the working chamber through a perforatedpanel known as a diffuser wall located on the righthand side of the chamber. The air then passesacross the working chamber and out through adiffuser wall on the opposite side where it is againpassed over the heater bank and recirculated.During this continuous process, a portion of theheated air is exhausted through a vent located atthe top of the working chamber to eliminate moistureand fumes which may arise from the material in theoven. The exhausted air is replaced by new airbeing drawn in through the intake port.

Mechanical Convection Ovens provide the mostefficient means of heat transfer as well as the mostreproducible test conditions for successiveoperations. They provide rapid heat-up time for highdensity loads, shortened recovery period inproduction operations where the door is frequentlyopened, and a minimum difference in uniformity forextremely heat sensitive materials. These ovensare microprocessor controlled. The temperaturerange of the oven is ambient +15°C minimum to325°C maximum.

These controllers cycle heat "On/Off" in split-secondintervals based on input from a Platinum ResistanceTemperature Device (RTD) sensor. The controllerdisplays temperature in °C. When this type ofcontrol is combined with the appropriate innerchamber design, precise temperature control fromambient +15°C to 325°C is achieved.

Another backup - safety, is a separate adjustable"HIGH LIMIT" control which turns the heater "Off", ifthe selected limit is attained. A glowing red light willindicate this condition.

The timer, located on the front panel, is springwound. It will allow the heater to be turned "Off" aftera preset time (maximum of 12 hours) or to continueto heat at the desired chamber temperature byturning the timer knob to the "HOLD" position.

The air continues to circulate within the chamberafter the heater is turned "Off" as the blower motoris still operating.

Installation

WARNINGINSTALLATION SHOULD BE COMPLETED BYQUALIFIED PERSONNEL ONLY.

Oven Location:

Best operating results are obtained by choosing alocation as free as possible from dust, drafts, orsevere temperature changes which can affect theperformance of the oven. All four legs of the ovenare adjustable to compensate for unevenness ofthe installation site.

An electrical source of proper characteristics shouldbe near at hand. The ambient temperature shouldbe between 10° and 40°C. Allow if possible, 1-5feet of free space from left oven wall. This spacewill allow easy access to the electricalcompartment of the oven for maintenance. In anycase, 6 inches of free space should be provided forproper ventilation of the electrical compartment.

Electrical Connections: Important (Please readcarefully).

WARNINGFOR PERSONAL SAFETY, THIS APPARATUS MUSTBE PROPERLY GROUND.

All models are supplied with a junction box locatedon the rear of the oven. The National ElectricalCode must be observed for proper fusing and sizeof service wires. Electrical power must be suppliedto the oven with permanent wire connections as aline cord is not provided. The service wires shouldbe connected to the three conductors inside thejunction box by a QUALIFIED ELECTRICIAN. Thegreen conductor furnished with the oven must beconnected to a well grounded conduit/system.

The electrical ratings for each model are printed onthe nameplate attached to the oven.

Electrical Connection Check Points:

1. Have proper connections been made at thejunction box?

2. Are all wire connections tight?3. Are service wires size adequate to carry the

load?4. Is the oven properly grounded?5. Is the oven connected to a properly fused

branch circuit?

Explanation of Controls"Power" Switch:

Controls all electrical power to the oven whenenergized. The blower motor will always be inoperation when the "Power" switch is "On".

"High Limit" Control:

The function of this thermostat is to control theoperation of the heater if either the microprocessoror RTD should fail. During normal operation, thecontrol is set so that the pilot lamp, above thecontrol knob, does not glow. A glowing lamp indicatesthat the heater is not energized. When the controlknob is rotated to its maximum position (fullyclockwise), the maximum chamber temperaturewill be limited to 345°C.

"Temperature Control":

“TEMPERATURE” Controller: Themicroprocessor temperature controller providedcontains two digital displays - the upper displayindicates chamber temperature in °C and the lowerdisplay indicates the desired operating temperaturein °C.

1. Set (SET) key is used to access the set valuesfor Temperature Control.

2. Setting digit shift left key — moves to andhighlights digit to be changed.

3. Set-value decrement key is used to decreasethe value of the number highlighted.

4. Set-value increment key is used to increasethe value of the number highlighted.

5. Present Value (PV) is the actual chambertemperature.

6. Set-value (SV) is the Temperature Set ValueDisplay (setpoint or desired temperature).

7. First control output (OUT(1) lamp lights upwhen control output (heat) is turned ON.

"Timed Heat":

It is a 12-hour spring-wound timer with a "HOLD"feature. It turns off the heater after preset time ofthe timer has elapsed, but the blower motor staysenergized and continues to circulate air throughthe chamber. During normal continuous operationof the oven at a desired temperature, the timerknob should be turned to "HOLD" position(counterclockwise).

"Air Volume Control":

It is a mechanical setting and controls the amountof heated air entering the working chamber. Thereference dial is numbered 1 through 9. The settingis made by turning the knob slightlycounterclockwise, sliding it to a desired position onthe scale and locking it by turning clockwise.Although the scale is numbered linearly, the airvolume increase is not linear. The air volumeincreases are relatively small at the lower end ofthe scale and large when adjusted at the upperend. The "one" setting on the scale provides theminimum airflow, and a setting of "nine" will supplythe maximum airflow.

NOTETHE AIR BLOWER OPERATES AT ALL TIMES WHENTHE "POWER" SWITCH IS "ON".

Operation

1. For nominal ventilation, open the exhaustvent and air intake vent shutter capsapproximately 50%. The air intake vent is tothe left when facing the front of the oven.

2. Set "Air volume" control to the midposition.

3. Turn the "High Limit" control fully clockwise.

4. Turn the "Timed Heat" knob to the "Hold"position for continuous operation at a desiredtemperature setting. If a controlled time period,up to 12 hours, is required, rotate the knob tothe desired hourly increment.

NOTEIF THE TIMER KNOB IS AT THE ZERO POSITION,THE HEATER WILL NOT OPERATE.

5. Press the "Power" switch to the "On" positionand observe operation.

6. Depress the appropriate “UP” or “DOWN”button until the desired setpoint temperatureis displayed in the lower display.

7. To set the temperature:• Press the SET key once. The right digit will

flash.• Select a value for this digit by pressing the

/\ or \/ key until the value is displayed.• Press the < key to select the next digit to be

changed. Use the /\ or \/ key until thedesired value is displayed.

• Once the readout is displaying the desiredtemperature setpoint, press the SET key toenter the value into the controller.

8. Allow the chamber to stabilize at the select"SP" temperature which can be observed onthe upper display [Time to reach maximumrated temperature (325°C) is approximately60 minutes].

9. Set the "High Limit" thermostat by rotating theknob counterclockwise until the red pilot lightturns "On". It indicates that the "High Limit"thermostat has taken control and that theheater has been de-energized. Once thisoccurs, rotate the knob clockwise one division.

NOTETHIS ADJUSTMENT FOR THE "HIGH LIMIT"THERMOSTAT SHOULD BE DONE ONLY WHENTHE CHAMBER TEMPERATURE IS STABILIZED ATTHE DESIRED SETPOINT TEMPERATURE.

Troubleshooting

CAUTIONSERVICE SHOULD BE PERFORMED BY QUALIFIEDSERVICE PERSONNEL. DISCONNECT THE UNITFROM ITS ELECTRICAL SOURCE. DISCONNECTINGANY COMPONENT FROM THE CIRCUIT WITHOUTPRIOR REMOVAL OF THE POWER SOURCE MAYCAUSE DAMAGE TO OTHER CIRCUITCOMPONENTS.

To use this chart, find the applicable symptom andperform applicable checks and/or tests in the orderthey are listed (1 through 11).

Symptoms

A. Temperature not uniform or fluctuating.B. Temperature is being controlled at the wrong

temperature.C. Low heat (not reaching desired setpoint

temperature, "SP").D. Constant heat (overheating).E. No heat.

Possible Causes/Test Procedure/CorrectiveAction:

1. Wiring (loose, broken or shorted):

Improper wiring is listed first because it isapplicable to all symptoms. It is not necessaryto disassemble the oven and check all wiringand connections at the first indication of aproblem. However, whenever you suspect acomponent is the cause of the problem, alsocheck all wiring and connections associatedwith that component and/or problem).

2. Door/Gasket (Misaligned/Dirty):

Heat Loss - Inspect door gasket to makecertain it fits firmly against the chassis at allpoints. Replace if damaged.

3. Vent Shutter Cap:

Make sure the vent shutter cap is not closed.Open to maximum (to maintain highertemperatures, vent shutter cap may have tobe partially closed).

4. Loading:

Test the unit when empty: if results aresatisfactory, the chamber was improperlyloaded. Redistribute the load.

5. "High Limit" Thermostat:

a. Ensure "High Limit" is set as outlined in the"OPERATION" section.

b. If the red pilot light is glowing at all times nomatter the position of the "High Limit" knob (atambient temperature), the "High Limit" is badand should be replaced (See "PARTSREPLACEMENT", Page 7).

100 138.50

150 157.32

200 175.84

250 194.08

300 212.03

7. Solid-State Relay:

With 3.5 to 26VDC between terminals (+)3and 4 of the solid state relay (when themicroprocessor controller's OUT 1 LED isglowing this voltage should be present, if not,check microprocessor controller), check for(AC) voltage between terminals 1 and 2 ofthe solid-state relay (it should beapproximately 1-2 VAC).

Disconnect terminal (+)3 from the solid-staterelay and verify that the voltage betweenterminals 1 and 2 = "LINE" voltage.

If you have approximately 1 VAC with terminal(+)3 disconnected or have "LINE" voltagewith 3.5 to 26VDC present, replace the solid-state relay.

8. "CALIBRATION":

Perform "CALIBRATION" as outlined in the"CALIBRATION/TEMPERATURE OFFSET"section on page 6.

9. Heater Element(s):

The heater bus bar terminals are located inthe left side compartment. Remove the outsideleft panel for access. A continuity check canbe made on the heaters to ascertain whetherbroken or open. Remove one of the wiresfrom a bus bar before taking measurement.There are two heater banks in parallel so awrong value of resistance could indicate oneof the banks is open.

The cold heater resistance should beapproximately:

Model 605, 5.7 ohms for 115V/120V modelModel 605, 23 ohms for 208V/230V modelModel 625, 15 ohms for 208V/230V modelModel 645, 11.5 ohms for 208V/230V model

10. Microprocessor Controller:
