INTRODUCTION

The Stackable LCC/LCD series OVEN offers HEPA filtration for processes where
minimization of contamination is essential. The removable HEPA (High Efficiency
Particulate Air) filter is designed to provide a constant flow of 99.97% clean air to the
product being heated. The HEPA filter with silicone seal provides 99.99% filtration. A
magnehelic differential pressure gauge monitors pressure drop across the HEPA filter.

The oven’s operator interface components are located on the hinged control panel at
the front of the oven. Power components are located on the equipment panel, behind
the hinged control panel, for easy access. Electrical components are either touch-proof
or are shielded with Lexan to prevent accidental exposure during maintenance and
troubleshooting.

The LCC/LCD series design offers a stackable oven body. Multiple oven systems of
two or three oven stack options are available. When multiple ovens are operated, the
Despatch Protocol Plus controllers may be networked together with a Modbus
communication option. Optional Despatch Protocol Manager software is used to enable
customer PC control of multiple ovens.

The stackable units are available in air or nitrogen (noted with an N suffix)
atmosphere.
Model numbers that begin with the designation LL*1-* are without HEPA filter.

Power

If your line voltage is much lower than the oven voltage rating, heat up time is
significantly longer and motors may overload or run hot. If your line voltage is higher
than the nameplate rating, the motors may run hot and draw excessive amps. If the line
voltage varies more than 10% from the oven voltage rating, some electrical components
such as relays, temperature controls, etc. may operate erratically.

INSTRUCTIONS

The INSTRUCTIONS section provides directions on unpacking, installation, operation
and maintenance of the Despatch Stackable LCC Series Ovens.

Unpacking and Inspection

Remove all packing materials and thoroughly inspect the oven for damage of any kind
that could have occurred during shipment.

• See whether the carton and plastic cover sheet inside carton are still in good
condition.

• Look at all outside surfaces and corners of the oven for scratches and dents.

• Check the oven controls and indicators for normal movement, bent shafts,

cracks, chips or missing parts such as knobs and lenses.

• Check the door and latch for smooth operation.

• Check the filter carton for damage.

If there is damage that could have happened during shipment follow these instructions:

1. Contact the shipper immediately and file a written damage claim.

2. Contact Despatch Industries to report your findings and to order replacement

parts for those that were damaged or missing. Please send a copy of your
filed damage claims to Despatch.

3. Check the packing list to make sure you have received all the specified

components of the oven system. If any items are missing, contact Despatch
Industries to have them forwarded to you.

4. Complete the warranty card and mail it to Despatch within 15 days after

receipt of the equipment.

Set-up

1. Select the location for installing
your oven.

Single Oven Placement

Place the oven on a bench top or other framework capable of holding at least
250 pounds. The oven must have a minimum of three (3) inches in the rear to
provide proper ventilation. If possible, provide room at the sides and rear of the
oven for maintenance. The oven exhaust opening is at the rear of the left side of
the oven; allow at least two (2) inches clearance here as well. The oven may be
placed next to another cabinet on its right, or next to another oven, with three­quarters of an inch clearance (measure with door open).

Make sure the oven is level and plumb; this will assure proper heat distribution
and operation of all mechanical components.

Multiple Oven Placement

Up to three ovens may be stacked vertically, either with or without the optional
framework / base supplied by Despatch. NOTE: in the LCC1-51 model, only two
ovens may be stacked vertically. Make certain that the supporting surface is
capable of holding the weight of three ovens (750 pounds, not including support
framework) or weight of two ovens in the LCC1-51 models.

The holes in the rear oven feet may be used to bolt the ovens together by
removing the hole plugs in the top of the mating oven beneath.

2. (Nitrogen models only) Connect the nitrogen supply line to the inlet marked
nitrogen on the side of the oven. The nitrogen supply should run at 70 PSI but
not more than 80 PSI. Check for leaks.

3. (Nitrogen and Water Cooled Models) Install water connection for cooling coils to
the inlet marked "Water Inlet." Verify the valve on the flow meter is turned off
(fully clockwise). The water supply to the oven must not exceed 100 PSI. It is
recommended to install a regulator to prevent any surge. Check for leaks. Slowly
open the valve on the flowmeter and allow any air to bleed out. Failure to do this
will result in damage to the flowmeter. Repeat this procedure if water supply is
shut off. Adjust the flowmeter to 3 gpm (recommended amount of flow.

4. (Nitrogen Models only) Make the drain connection at the side of the oven. Note
there are two drain connections: water outlet and water drain (see photo on next
page). NOTE: The water outlet may be connected in a closed loop system, but
the water drain must be left in an open-to-atmosphere condition.

WARNING:
Do not use the oven in wet, corrosive or
explosive atmospheres unless this oven is
specifically designed for a special
atmosphere.

CAUTION: Design the drain system to prevent operator injury from high temperature
or pressure buildup. Piping must be able to withstand short periods of up to 500 °F
(260 °C) temperatures [662 °F (350 °C) for LCD ove ns]. Drain lines should be

8

insulated or warning labels installed stating that a hazard exists.

WARNING:
Never allow drain to be plugged as a hot oven will generate a small amount of steam
when the water is first turned on. Steam burns.

HEPA Filter Installation

Model numbers that begin with the designation LL*1-* are without HEPA filter.
If your oven is a LLC*-3 or LLD*-3, disregard instructions of the HEPA filter.

Technicians responsible for installing the filter should use caution. The filter is delicate
and must not be damaged during installation. Any filter unit dropped, whether or not in
the carton, should be examined for damage. Equally important, the filter unit must be
installed so that unfiltered air will not leak past the unit.

1. Remove the filter from the carton.
a. Place the carton on the floor. The floor must be clear of nuts, bolts, and

NOTE: Make certain that power is disconnected from the
oven before removing or replacing the HEPA filter.

similar protrusions, which would damage the face of the unit. Do not drop
or jar the carton.

NOTE: Repairing the damaged filter unit, particularly the medium, should not
be attempted by the user. Any unit so repaired must be retested to assure
that hidden damage does not exist which will reduce filtering efficiency.
Repair and retest is uneconomical for most users.

b. Tilt the carton on one corner. Be sure to handle the carton at opposing

corners.
c. Remove the sealing tape and fold the flaps of the carton back.
d. Gently upend the filter to place the exposed end of the filter on the floor.

Do not jar the filter.
e. Pull the carton from the filter unit. Do not pull the filter from the carton.

2. Inspect the filter. Use a strong lamp to examine the exposed areas of both faces
to assure that no breaks, cracks, or pinholes are evident. A flashlight, can be
used in a darkened room.

• Look for visible defects with the light projected along the full length of
each channel created by the separators. Translucent spots may not
necessarily indicate holes or cracks but may simply be variations in
thickness of the filter medium.

• Check that the adhesive seal around the filter unit faces are complete
and unbroken.

17

• Check the corner joints of the frame for adhesive sealing and
tightness.

• Check that the gaskets are cemented firmly to the filter frame and that
the gasket pieces are butted or mated at the joints.

3. Pull the shelf out from the oven and set it aside.
NOTE: Make certain that power is disconnected from the

oven before removing or replacing the HEPA filter.

4. Loosen the two screws at the upper and lower corners of the right rear of the

chamber. Pull out the shelf support/duct as a single unit and set it aside.

5. Note the position of the threaded rods behind the duct assembly on the right

side. The HEPA filter will be fitted over these rods.

6. Remove the brass nuts and washers from the rods that are temporarily locking

the rods to the oven wall. These nuts will be reused to hold the filter in place.
(LCC1-16 only: Remove filter frame to be reinstalled after filter.)

7. (LCC1-16 only:) Remove the HEPA filter (shipped separately) from its container.

NOTE: The seal side goes toward the wall of the oven. Place it inside the
chamber and install filter mounting frame over rods. Push filter tight to rear wall
with mounting frame.

(LCC1-51 only:) Remove the HEPA filter (shipped separately) from its container.
NOTE: The seal side goes toward the wall of the oven. Place it inside the
chamber and install filter mounting angles (shipped separately) over rods. Push
filter tight to rear wall with mounting angles.

8. Reinstall the washers and brass nuts to tighten the filter frame down. Tighten the

four nuts alternately for even tightness. Be careful not to over tighten. Correct
installation torque is 28 +/- 3 in-lbs. Be sure to compress the gasket evenly and
equally at all points with the filter frame completely covering the opening.

9. Reinstall the shelf support/duct assembly using the two screws removed earlier.

10. Reinstall the oven shelf.

HEPA Filter Burn-off

The burn-off process will take place in any piece of equipment where a new HEPA filter

18

is used at temperatures above 180°C / 356°F. There will be smoke, possibly a pungent
odor, and a light residue on interior surfaces. This is the result of oxidation of the
binder. Most of the binder will leave the filter after running at a temperature of
260°C/500°F for 48 (forty-eight) hours. Check the oven for particles or the exhaust for
smoke and odor to determine that the process is finished.

Select a location for this process where the smoke and odor generated will be ventilated
with the least amount of interruption and inconvenience. Ideally this will be in the final
location for the oven. However, it may be a receiving dock, some well ventilated space
or even outside if the weather is acceptable. If this location is a very clean area, then
special attention must be given to an exhaust hook-up that will capture the smoke and
odor. The post-cleaning (i.e. oven wipe down) may also generate dust, and care should
be taken if this is done in a clean room.

The following procedure is recommended:

1. Locate the equipment exhaust opening where chamber air is being expelled.

If the oven filter is burned off in a clean area, be sure to handle the equipment
exhaust appropriately. If the equipment is large and the exhaust stack is a
permanent service connection, it should be connected before the burn-off
process is run. If the equipment is small with no permanent exhaust duct
required, arrange a temporary connection out of the clean area that will handle
the maximum temperature of the equipment. Direct the smoke and odor outside,
or to a highly ventilated area.

2. Set the temperature control at the maximum process temperature.

• Silicone: Ramp at 1.25° C/min to 260° C and soak for 48 hours.

• Media Pack: Ramp at 1.25° C/min to 260° C and soa k for 48 hours.

• Termikfil: Ramp at 5° C/min to 350° C and soak for 48 hours.

3. Start the fan after making the electrical power connections.

4. Energize the equipment heater.

Use enough fresh air to remove the smoke, while still being able to achieve and
maintain the necessary temperature. The completion of the burn-off period
should be based on the particle level in the oven or smoke-free exhaust and
minimal odor level.

The filter hold-down nuts should be checked after burn-off and tightened again if
necessary. For best oven particle control, this step should be repeated on a
regular basis.

19

NOTE:

If it is necessary to move the equipment after the burn-off process, considerable
care should be used. The binder which gives strength to new filters is now burned-off and
the media is very fragile. Rough handling of either the filter alone or the equipment with the
filter installed is not recommended as it may tear the media and lead to reduced filter
efficiency. Removal of the filter after heating can also result in damage to the frame seal,
and is only recommended when replacing the filter.

20

OVEN OPERATION

Oven

The stackable LCC oven is a class 100 clean room oven with HEPA (High Efficiency
Particulate Air) filtration. This oven is ideal for processes where minimization of
contamination is essential.

Forced convected airflow provides rapid uniform distribution of heat. A HEPA (High
Efficiency Particulate Air) filter is mounted in a stainless steel frame in the
supply plenum. These filters are 99.97% effective in filtering 0.3 micron particles.

The cooling fan, is controlled on/off by an event relay in the Protocol Plus Control. The
cooling fan is used for rapid cool-down at the end of the process cycle, or to maintain
low temperature setpoints during process cycle. It may also be turned on at the start of
a process cycle to assure that starting temperature is less than 70° C.

The nitrogen models have stainless steel water coil which permits rapid cool down and
lower temperature operation. The nitrogen oven comes with an adjustable flowmeter a
for adjusting purge rate, and needle valve for setting maintain rate, separate solenoid
valves for purge and maintain operation and a pressure relief exhaust port. An exhaust
fan which powers on whenever the oven is running maintains consistent chamber
pressure control with varied exhaust stack conditions.

The oven has a type 304-2B stainless steel interior and a type 304-#4 stainless steel
interior. All interior seams are continuously welded on the insulation side. This protects
the work chamber from contaminated air and permits chamber washing without
damaging the insulation. Interior ductwork may be easily removed for cleaning. Heater
frame, fan wheel and motor shaft are constructed of stainless steel.

All controls are mounted on the front of the oven for easy operation and readability.
Two electropolished stainless steel wire shelves are provided. The shelves are
removable and adjustable on two inch centers.

21

System Control

A Despatch Protocol Plus controller/high-limit device is used to control the unit. This is
located on the control panel of the oven.

• The Protocol Plus controller provides temperature control for the process.

• The Protocol Plus controller provides outputs for the cooling fan, door lock

switch/door release pushbutton, and optional beacon light.

• As many as eight (8) profiles for oven heating cycles are stored in the Protocol
Plus controller. These are accessed by the operator using the Protocol Plus
keypad.

• The Protocol Plus controls the solenoid valves in an inert atmosphere oven for
purge and maintain operation.

• Optional MODBUS RS422/485 serial communications hardware may be installed
on the Protocol Plus controller, with a 9-pin communications port located on rear
of oven. This provides the ability to network the oven(s) with a host PC.

• The optional three-color beacon light provides visual indication of the cycle
status, as follows:

Green – Cycle in process
Yellow – Standby. Operator has unloaded product. Oven waiting for next

cycle.

Red – Error or fault condition.

• The optional High-Limit Alarm indicates when the high-limit setpoint has been
exceeded. An illuminated Alarm Silence switch lets the operator turn off the
alarm while providing a red warning light until the high-limit condition is corrected.
(See High-Limit description later in this manual.)

HEPA Filters

HEPA (High Efficiency Particulate Air) filters are used to limit particulate size in the work
chamber to 0.3 microns or less.

NOTE: Chamber temperature transitions must not exceed 1.5° C/minute in order to
maintain class 100 chamber conditions in the LCC models. for ramp rates greater than

1.5° C/minute and up to 5° C/minute, the LCD model will maintain class 100 chamber
conditions.

Definitions

HEPA - High Efficiency Particulate Air
Burn-Off - A process for getting rid of the binder and D.O.P. contained in the filter from

the manufacturing and testing function.

D.O.P. - Dioctyl Phthalate - Aerosol particles of submicron size used in the testing

phase to spot defects or measure filter efficiency.

Binder - An organic substance that is used in the construction of the filter that gives

some structural strength to the media.

Filter Packaging and Shipping

Packaging practice varies among the filter unit manufacturers. Normally units are
packaged in cardboard cartons with various approaches for internal strengthening and
impact-resistance of the container. The shipping carton normally is marked with a
vertical arrow and "This Side Up". A filter unit is placed in the carton so that the pleated
folds are vertical (running from top to bottom - not side to side).

Filters should be shipped, handled and stored with the pleats in the vertical position. If
shipped with the pleats in the horizontal position, the filter medium may break at the
adhesive line. If handled or stored with the pleats in the horizontal position the pleats
may sag.

Moreover, the filter unit should be installed with the pleats in the vertical position. When
installed in the horizontal position the pleats form shelves for the collection of entrapped
material. The accumulated weight of this material causes sagging and leads to an early
failure of the unit.

24

Handling

The filter is shipped in the original carton or package that the filter manufacturer uses.
This will give good storage and maximum protection from dirt and moisture.

HEPA filters should be stored and moved in the shipping carton with in the upright
position. Handling should be kept to a minimum. During installation the filter should be
removed from the shipping carton and installed directly into the oven.

If for any reason an unpackaged filter unit must be placed with its face on the floor or
other surface, the surface must be cleared of every object or irregularity, which might
damage the filter pack.

HEPA Filter Validation Testing

This section describes the Despatch position and recommendations for HEPA filter
testing and oven validation procedures. Despatch guarantees that the filters will meet
specified efficiency ratings when the filter is:

• properly installed

• run at or below 200° C, at a constant temperature

• run before burn-in

D.O.P. Testing

In D.O.P. testing aerosol particles of submicron size are used to spot defects or
measure filter efficiency. Degenerative by-products of this test are distributed
throughout the oven chamber upon heat-up. Therefore Despatch does not recommend
D.O.P. filter testing.

Class 100 Testing

Despatch guarantees the environment within the oven to be Class 100. This
classification is based upon measurement of the particulate level within the oven work
chamber.

Class 100 testing may be performed before or after a proper filter burn-in procedure has
been performed. Despatch will guarantee Class 100 conditions measurements based
on two methods of test. The direct method of test employs an extraction-type
particulate analyzer. The indirect method involves particle settling over a specified
period of time onto a clean disk.

25

Validation Testing

Based on the issues discussed in this section, Despatch recommends the following test
sequence for pharmaceutical Class 100 ovens.

1. Proper installation of the HEPA filters.

2. Ambient air challenge to determine integrity of oven chamber and filter gaskets.

3. Proper filter burn-off procedure.

4. Class 100 testing inside the work chamber.

The Necessity of the Burn-off Process

HEPA filters contain a binder material, which protects the filter media during production
and shipping. This smoke is typically not desirable during normal operation of the oven.
Burning off the binder will ensure a clean process at elevated temperatures.

When the binder is burned out of the filter media, the filter becomes very fragile, too
fragile to withstand normal shipping and handling. For this reason, Despatch does not
perform the burn-off procedure. The burn-off process is not necessary at temperatures
under 200° C.

Filter Unit Replacement

Replacement of the filter unit is necessary for these reasons:

• Resistance, or pressure drop, across the filter unit. Maximum level of resistance
in inches (water gauge) will vary depending upon the operation of the filter and
the available fan capacity. Adequate fan capacity must be available.

• Loss of efficiency (leakage), determined from air-sampling measurements made
downstream of the filter unit.

• Visible damage or rupture of the filter media in a unit.

• Change in process application.

• Excessive build-up of lint or combustible particulate matter on the filter unit.

26

• Water droplets in airstream through filter, free water (RH = 100%), will saturate
filter very quickly and may cause burnout or holes in burned off filter media.

• High level of radiation in the vicinity of the filter unit.

27

HEPA Filter / Magnehelic Pressure Gauge

The LCC Series oven is equipped with a Magnehelic pressure gauge which measures
the pressure in front of the HEPA filter. As the filter becomes dirty, the pressure will
increase. Despatch recommends changing the filter when the pressure is 1” w.c.
greater than when the filter was first installed.

Since the pressure can be affected by many factors involved in the installation, it is
important to record the pressure of a new filter, so that the pressure readings can be
periodically checked against this baseline. The table below is provided for recording
this information.

For a nitrogen atmosphere oven, the pressure reading also gives an indication of the
integrity of the seals. If the pressure recorded in Columns D or E decrease in time, the
oven seals should be inspected.

OPERATING

Users and operators of this oven must comply with operating procedures and training of
operating personnel as required by the Occupational Safety and Health Act (OSHA) of
1970, Section 5 and relevant safety standards, and other safety rules and regulations of
state and local governments. Refer to the relevant safety standards in OSHA and
National Fire Protection Association (NFPA), Section 86 of 1990.

Loading the Oven

Despatch Industries cannot be responsible for either the process or process
temperature used, or for the quality of the product being processed. It is the
responsibility of the purchaser and operator to see that the product undergoing
processing in a Despatch oven is adequately protected from damage.

Carefully following the instructions in this manual will help the purchaser and operator in
fulfilling that responsibility.

When loading the oven avoid spills of anything onto the heater elements or onto the
floor of the oven. Do not place the load on the oven floor plate. This may cause the
load to heat unevenly and the weight may cause shorting out of the heater elements.
Use the shelves provided.

The two shelves are designed to be pulled out about halfway without tipping. Do not
overload the shelves.

Distribute the workload evenly so that airflow is not restricted. Do not overfill your oven.
The workload should not take up more than two-thirds of any dimension of the inside
cavity.

29

Pre-Startup Checklist

• Know the system. Read this manual carefully. Make use of its instructions and
explanations. The know how of safe, continuous, satisfactory, trouble-free
operation depends primarily on the degree of your understanding of the system
and of your willingness to keep all parts in proper operating condition.

• Check line voltage. This must correspond to nameplate requirements of motors
and controls. A wrong voltage can result in serious damage. Refer to the
section on power connections in the INTRODUCTION of this manual.

• Check fresh air and exhaust openings. Do not be careless about restrictions in
and around the fresh air and exhaust openings and stacks. Under no condition
can they be permitted to become so filled with dirt that they reduce airflow.

WARNING: Do not use any flammable solvent or other flammable material in this
oven. Do not process closed containers of any substance or liquid in this oven
because they may explode under heat.

Maintenance

Do not attempt any service on this oven before opening the main power disconnect
switch.

Checklist

• Keep equipment clean. Gradual dirt accumulation retards airflow. A dirty oven
can result in unsatisfactory operation such as unbalanced temperature in the
work chamber, reduced heating capacity, reduced production, overheated
components, etc. Keep the walls, floor and ceiling of the oven work chamber
free of dirt and dust. Floating dust or accumulated dirt may produce
unsatisfactory work results. Keep all equipment accessible. Do not permit other
materials to be stored or piled against it.

• Protect controls against excessive heat. This is particularly true of controls,
motors or other equipment containing electronic components. Temperatures
greater than 51.5° C (125° F) should be avoided.

• Establish maintenance & checkup schedules. Do this promptly and follow the
schedules faithfully. Careful operation and maintenance will be more than paid
for in continuous, safe and economical operation.

• Maintain equipment in good repair. Make repairs immediately. Delays may be
costly in added expense for labor and materials and in prolonged shut down.

• Practice safety. Make it a prime policy to know what you are doing before you do
it. Make CAUTION, PATIENCE, and GOOD JUDGMENT the safety watchwords
for the operation of your oven.

Lubrication

Fan motor bearings are permanently lubricated. All door latches, hinges, door operating
mechanisms, bearing or wear surfaces should be lubricated to ensure easy operation.

Theory of Control Operation

The Protocol Plus is a modular microprocessor based digital temperature controller. The
Protocol Plus operates as a dual functioning controller/high limit instrument. The control
portion utilizes a time-proportioning voltage signal to control heating devices with
minimal temperature fluctuations.

The high limit portion protects the product and/or the oven from overheating. If the
product being processed has a critical high temperature limit, the high limit setpoint
should be set to a temperature somewhat below the temperature at which the product
could be damaged. If the product does not have a critical high temperature limit, the
high limit setpoint should be set 5 to 15 degrees higher than the maximum programmed
setpoint at which the oven will operate.

36

Stopped Mode: All control and relay outputs are off. Stopped Mode is integrated

into each of the following four modes of operation.

Manual Mode: Control operates as a single setpoint control until Stopped mode is

accessed

Timer Mode: Control operates as a single setpoint control until preset time period

has expired.

Profile Mode: Control operates as a ramp/soak profiling control until the end of

the profile. 8 profiles are available with up to 8 ramp/soak segments
in each profile.

Auto Start Mode (optional): Control may automatically start Manual, Timer, or

Profile mode based on a preset time and day.
Requires the optional real-time clock feature.

The optional event outputs can be utilized during Manual, Timer, or Profile modes.

Setup Mode

The control has a Setup Mode which provides access to control configuration and
programming of profiles. The Setup Mode contains ten separate electronic Pages where
the configuration and programming parameters (Menu items) are found. The Setup
Mode Pages are described in detail elsewhere in this manual.

Fast Start Mode

The Protocol Plus control has the ability to automatically start an operating mode when
power is applied. This feature may be useful if the same mode of operation is used
everyday. The user can turn on the power and the oven will start the desired process
automatically. The Fast Start Mode is controlled by the Power-Up Start parameters on
the Control page (see Setup Mode).

38

High Limit

The control has an integrated high limit function which will disable the heater output
when tripped. If the high limit does trip, the relay will need to be manually reset. When
the high limit relay is tripped, the Hi-Limit indicator will be lit. Allow the oven to cool
several degrees (or increase the high limit setpoint) and then press the Reset key. The
indicator will turn off.

High-Limit temperature readout is provided on LCD Line #2 in all Modes (Stop, Run,
Hold, and Standby) except Setup Mode. High-Limit temperature is displayed for 10
seconds, alternating with current Mode and Status display for 10 seconds.

The control will not allow the high limit setpoint to be set below the current setpoint
value.

Outputs

The Protocol Plus control has seven different outputs available.

• Heating output: The control output is a DC voltage open-collector output which
is time-proportioned and designed to control a heat control device such as a solid
state relay.

• High limit: The high limit output is a form C relay which is energized under
normal operating conditions. If the control senses a temperature higher than the
high limit setpoint, or if there is a sensor error, the high limit relay will de-energize
until the condition is cleared and the Reset key is pressed. When the high limit
relay is de-energized, the heater is disabled.

• Retransmission: The retransmission output is a DC 1 to 5 volt or 4 to 20 ma
(DC) signal that is proportional to the process temperature. The signal can be an
input to other devices such as a chart recorder.

• Relay (four optional outputs): The four form A dry contact relay outputs can be
configured to function as alarms, events, or end of cycle. These outputs can be
utilized in Manual, Timer, or Profile Mode.

Profile # There are eight profiles available.
Segment# Recipe segments 1 through 8 may be programmed, each with its own

set of events, ramp and soak times, and soak temperature.

Ramp Time The time required to ramp from one setpoint up to another setpoint.

Values between 0 and 99:59 are allowable. In the Protocol Plus
controller, the profile ramp and soak times are stored without units.
Units are set as either hours and minutes (HH:MM) or minutes and
seconds (MM:SS). The setpoint will automatically increment from the
actual temperature to the soak temperature.

EV1 through 4 From 1 to 4 events may be programmed into the ramp time portion of

each segment here. These typically involve actuating/disabling relays
to close/open valves or perform other relay-controlled functions.
NOTE: These will only actuate when the controller has the relay cards
installed and programmed for an event.

Soak Temp. The temperature setpoint of a particular segment is entered here; it

can range from -18 to 540 degrees C (0 to 1000 degrees F).

Soak Time The duration of soak is entered here; the value can range from 0 to

99:59.

EV1 through 4 From 1 to 4 events may be programmed into the soak portion of each

segment here. These typically involve actuating/disabling relays to
close/open valves or perform other relay-controlled functions. NOTE:
These will only actuate when the controller has the relay cards
installed and programmed for an event.

Hi Limit SP The high limit setpoint may be entered here; if the temperature

exceeds this value, the hi-limit will alarm and shut off the heater.

Loop From Values are No, Seq-1 to Seq-8.
Loop To Values are No, Seq-1 to Seq-8.
Loop Number Values are 0 - 99.

These values enable the operator to jump from a certain step to
another step of the recipe a preset number of times.

Profile Link Values are STANDBY/STOP/HOLD/1 - 8. When the profile ends, the

profile can hold the temperature setpoint while keeping the events
active, turn the heater off, hold the temperature setpoint at the end of
the profile, or jump to another specified profile.

Guaranteed
Soak Band

If the process temperature deviates from the setpoint by more than
this value, the soak timer is placed in a hold condition. The timer
continues when the process temperature falls within range.

Zone Calibration Page (Defaults on Page 71)

The Zone Calibration Page allows adjustment of the displayed temperature versus the
actual temperature measured by the control thermocouple. This may be desirable in
certain conditions where the center of the oven chamber is not the same temperature as
the control thermocouple. This may occur when the oven is not allowed to soak at a
constant temperature for long periods of time, or the oven is being used at high
temperature.

There is also a Factory Calibration Recovery which will restore the factory calibration
values when the control was first shipped by the manufacturer. This may be helpful if
the calibration has been lost and a calibration instrument is not readily available. To use
the Factory Calibration Recovery feature only, bypass the Zone 1 and Zone 2
calibration parameters by pressing the Menu key.

As an example, the control is displaying 400°F with the setpoint being 400°F, but the
center of the oven chamber is actually 395°F. This can occur due to oven wall losses
and product loading variations. The operator may change the zone calibration so that
the center of the oven is 400°F when the display re ads 400°F. In this case operate the
oven in manual mode with a setpoint of 400°F. Recor d the center of the chamber (as
measured with an independent sensor). Access the Zone Calibration Page and enter
this measured value as the Zone 2 Actual value, with 400° as the Zone 2 Displayed
value.

Zone 1 can be adjusted using the same method at a lower temperature. The instrument
will then create a linear offset based on the Zone1 and Zone 2 Actual temperature
values. Note that the oven does not have to be heated to adjust the zone parameters if
the zone values are known based on prior experience.

Sensor Calibration Page (Defaults on Page 71)

The Sensor Calibration Page has parameters which can change the internal calibration
of the temperature sensor input signal. There is a low and high calibration point for both
the control sensor and the high limit sensor. To calibrate the instrument, allow the
control to warm up for at least 30 minutes.

To access the Sensor Calibration Page, enter the Setup Mode (see description earlier in
this manual). Press the Page key until Control Sensor is displayed. Press the Menu
key.

The control may have the optional process value retransmission output feature. The
output is a 1 to 5VDC signal. To calibrate the retransmit signal, the RetOutLo and
RetOutHi values from the Control Page must be known. You may bypass calibrating
the control and high limit sensor input to access only the retransmit calibration by
pressing the Menu key until RetCalLo is displayed (skip steps 4-17).

To re-calibrate the instrument:

1. Disconnect the control and high limit sensor thermocouples.

2. Connect a calibration instrument with a type J thermocouple output to the
control sensor input. Allow the control to warm up at least 30 minutes.

3. Access Setup Mode.

4. Press Page key until -100F is displayed.

5. Press Menu key until Ctrl Sens -100F is displayed.

6. With Ctrl Sens -100F displayed, adjust the calibration instrument to Type J
thermocouple, -100 degrees Fahrenheit output.

7. Wait 30 seconds. Press the key.

8. With Ctrl Sens 1400F displayed, adjust the calibration instrument to 1400
degrees Fahrenheit output (Type J thermocouple).

9. Wait 30 seconds. Press the key.

10. When the control displays Ctrl Sens Done, disconnect the calibration
instrument from the control sensor input and connect it to the high limit sensor
input. Reconnect the control sensor thermocouple.

11. Press the Menu key until HL Sens -100F is displayed.

12. With the control displaying HL Sens -100F, adjust the calibration instrument
to -100 degrees Fahrenheit output (Type J thermocouple).

13. Wait 30 seconds. Press the key.

14. With the control displaying HL Sens 1400F, adjust the calibration instrument
to 1400 degrees Fahrenheit output (Type J thermocouple).

15. Wait 30 seconds. Press the key.

16. When the control displays HL Sens Done, disconnect the calibration
instrument from the high limit sensor input. Re-connect the high limit sensor
thermocouple.

17. To skip calibration of the retransmit signal, press the Page key twice to exit the
Sensor Calibration Page.

18. To calibrate the retransmit signal, press the Menu key until RetCalLo is

61

displayed.

19. Connect a calibration instrument with a type J thermocouple output to the
control sensor input.

20. Connect a voltage measurement device to the retransmit output terminals.

21. Set the calibration instrument output to the temperature value of the RetOutLo
parameter from the Control Page.

22. Adjust the RetCalLo * value using the keys until the voltage measurement
device reads 1VDC.

23. Press the Menu key.

24. Set the calibration instrument output to the temperature value of the RetOutHi
parameter from the Control Page.

25. Adjust the RetCalHi * value using the keys until the voltage measurement
device reads 5VDC.

26. Press the Menu key.

27. Press the Page key to exit the Sensor Calibration Page.

28. Calibration is now complete. Disconnect the calibration instrument and voltage
measurement device (if used).

29. Verify that the control and high limit sensor thermocouples are connected.
