TABLE OF CONTENTS
PREFACE ....................................................................................................................... iii
The LCC/LCD2-14PT-3 SERIES pass-through oven is equipped with sterile and nonsterile doors, for clean room operation. Safety interlock switches on each door prevents
both doors to open at the same time (these may be manually overridden if required).
The operator loads the product from the non-sterile side, and selects the program to
run. At the end of the process, the product is unloaded from the sterile side.
The LCC/LCD2-14PT-3 SERIES pass-through 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 prior
to filter burnoff. A magnehelic differential pressure gauge monitors pressure drop
across the HEPA filter.
The LCC2-14PT-3 Series ovens are rated up to 260 C, and the LCD2-14PT-3 Series
has a maximum temperature of 350 C.
The voltages available are 208V, 240V, 415V, and 480V,
3 Phase; with a 16kW heater.
The oven’s main operator interface components are on the hinged control panel located
on the non-sterile side. The power components; fuse blocks and motor starters are
located on the equipment panel, behind the hinged control panel for easy access. The
transformer and the heater SSR’s are located in the lower compartment with the
recirculation and exhaust/cooling motors. An EMO (emergency off) switch, and
indicator lights showing what step the process is in, is located on the sterile side control
panel. Electrical components are either touch-proof or are shielded with Lexan to
prevent accidental exposure during maintenance and troubleshooting.
The optional Despatch Protocol Manager software is used to enable customer PC
control of an oven. Despatch Protocol Plus controllers may be networked together with
a Modbus communication option when multiple ovens are operated.

WARNING:
Do not use the oven in wet, corrosive or
explosive atmospheres unless this oven is
specifically designed for a special
atmosphere.
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.
Set-up
1. Select the location for installing
your oven.
2. Make sure the oven is level and
plumb; this will assure proper
heat distribution and operation
of all mechanical components.
3. This oven has been designed for use in a clean room environment (sterile and
non-sterile rooms).
4. The oven has a four (4) inch diameter exhaust opening and is located on the left
side of the oven. The oven may be placed next to another cabinet on its right, or
next to another oven, with three-quarters of an inch clearance (measure with
door open). Exhaust air may reach 260° C on the LCC version and 350° C on
the LCD version. Make sure exhaust piping materials can withstand these
temperatures.
5. (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).
6. (Water Cooled Models) Make the drain connection at the side of the oven. Note
there are two drain connections: water outlet and water drain. 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.
7. (Water Cooled Models) Connect the compressed air supply line to the inlet
marked “Dry Air”. The compressed air supply should run at 70 PSI but not more
than 80 PSI. Check for leaks.
7
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!
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 650 °F (343 °C)
temperatures. Drain lines should be insulated and/or warning labels installed that a
hazard exists.

WARNING: 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.
WARNING: Make certain that power is disconnected from
the oven before removing or replacing the HEPA filter.
HEPA Filter Installation
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
similar protrusions, which would damage the face of the unit. Do not drop
or jar the carton.
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.
Check the corner joints of the frame for adhesive sealing and
tightness.
10
WARNING: Make certain that power is disconnected from
the oven before removing or replacing the HEPA filter.
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.
4. Loosen the screws at the sides and top of the supply duct/shelf supports on the
right side of the chamber. Pull out the duct/shelf support and set it aside.
5. Remove the brass nuts and washers from the rods that are holding the filter
frame in place. These nuts will be reused to hold the filter in place.
6. Remove and discard the conduit spacers from the rods behind the filter frame.
Place the filter in the oven with the seal side towards the right side oven wall.
Reinstall the filter frame using the nuts removed earlier. Make sure the filter face
is tight against the inside perimeter of the frame on all sides.
7. Reinstall the brass nuts and washers to tighten the filter frame down. Tighten the
six 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.
8. Reinstall the shelf support/duct assembly using the screws removed earlier.
9. 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
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.
11
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.
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 soak 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.
12
LCC2-14 HEPA High Limit
Filter High Limit
The LCC/D2-14*-3 series ovens have been equipped with a redundant high limit device
to protect the HEPA filter. The sensor for the high limit is located before the air inlet of
the HEPA filter. The high limit device is located in the lower compartment of the oven.
If the oven temperature exceeds the factory set Filter High Limit temperature, the high
limit will trip, shutting down the heater and protecting the HEPA filter.
Before resetting the high limit, determine the cause of the excessive temperature.
Under normal operating conditions the Filter High Limit should never trip. If the high
limit trips, it must be reset by removing the access panel to the lower compartment. The
high limit is located next to the transformer; press the reset button on the high limit. See
the MIC1162 reference manual for the operation of this high limit.
13
OVEN OPERATION
Oven
The LCC/LCD2-14PT-3 Series pass-through 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 prior to filter
burn-off.
The cooling/exhaust 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 oven has a type 304-2B 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.
Non-sterile side controls are mounted on the front of the oven for easy operation and
readability. The EMO (emergency off) switch and indicator lights are mounted on the
control panel on the sterile side. Two electropolished stainless steel wire shelves are
provided. The shelves are removable and adjustable on three inch centers.
14
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. See the section on the Protocol Plus controller
for detailed operation.
The Protocol Plus controller provides temperature control for the process.
The Protocol Plus controller provides outputs for the cooling/exhaust fan, and
door lock switch/door release pushbuttons.
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.
Indicator lights on the sterile side provides visual indication of the cycle status, as
follows:
Red (pilot light) – Non-Sterile Door Open
Yellow (pilot light) – Cycle On
Green (illuminated push button) – Cycle Complete (depress push button after
unloading and sterile door closed)
Indicator Lights
Optional MODBUS RS422/485 serial communications hardware may be installed
on the Protocol Plus controller, with two 9-pin communications ports located on
the front of the oven. This provides the ability to network the oven(s) with a host
PC.
15
The optional three-color beacon light on the non-sterile side 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 push-button lets the operator turn off
the alarm while providing a red warning light until the high-limit condition is
corrected.

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 1.25°C/minute in order to
maintain class 100 chamber conditions. An optional filter is available for transition rates
up to 5°C/minute. Consult factory.
Definitions
HEPA - High Efficiency Particulate Air
Burn-Off - A process for getting rid of the binder contained in the filter.
D.O.P. - Dioctyl Phthalate - Aerosol particles of submicron size used in the testing
phase to spot defects or measure filter efficiency. Despatch Industries DOES NOT
RECOMMEND use of this or other organic challenge agents.
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.
18
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 180°C, at a constant temperature
burned off at 260°C for 48 hours before running
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. These and other organic challenge agents
also present a fire hazard for this non-Class A (NFPA 86) oven. 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-off procedure
has been performed. Despatch will guarantee Class 100 conditions measurements
based on the direct method of test employing an extraction-type particulate analyzer.
An indirect method of testing involves particle settling over a specified period of time
onto a clean disk. Please consult the factory for expected levels.
19
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 off 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 process
temperatures consistently under 180°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.

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.

PROTOCOL PLUS CONTROL
The special features of the Protocol PlusTM control include:
PID tuning
Ramp/Soak programming of up to 64 segments
Segment looping and profile linking
Built-in manual reset high limit control
Built-in process timer
Dedicated LED display for process temperature
Multi-purpose two-line LCD display with backlight
Auto-tuning
Security access
Process temperature retransmission signal
Digital inputs for remote profile control
Real time clock
Optional relay outputs for events, alarms, or end-of-cycle signal
Optional RS232/RS422/RS485 MODBUS communications
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.

Operating Modes
The Protocol Plus control has five modes of operation available:
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: Control may automatically start Manual, Timer, or Profile mode
based on a preset time and day.
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).
30
High Limit
The control has an integrated high limit function which will disable the heater output

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, Seg-1 to Seg-8.
Loop To
Values are No, Seg-1 to Seg-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.
The Auto Start Page can be configured to automatically start Manual, Timer or Profile
Mode at a specified time and day. Note that if Auto Start Enable is set to Yes in the
Setup Mode, the Auto Start feature is not turned on - it is available to the operator to be
activated in Stopped Mode.
To configure the Auto Start feature:
1. Access the Setup Mode.
2. Press the Page key until Auto Start is displayed.
3. Press the Menu key. If there is no change in the display, the controller may not
have the realtime clock option.
4. Set Auto Start Enable to Yes.
5. Using the Menu key, scroll through the options available and use the keys
to set the mode desired for each day of the week. You may select from Manual,
Timer, or Profile 1 through 8.
6. When the mode is set press the Menu key.
7. Enter the time of day you wish the mode to activate.
8. Continue through the rest of the week by pressing the Menu key, or press the
Page key when done.
One Auto Start mode can be set for each day of the week. Exit the Setup mode by
pressing and holding the Page key for three seconds. Press the Select key until Auto
Start is displayed. Make sure the correct time and day is displayed. If not proper, set it
to the correct time on the Real Time Clock Page in the Setup mode.
To activate the Auto Start Mode,
1. On Auto Start page, Enable is set to Yes.
2. LCD reads Active on Line 1 in Auto Start Mode.
3. On Auto Start page Enable set to No, will deactivate Auto Start Mode.
Note that once you activate Auto Start, you can continue to use all operating modes as
normal. If an operating mode is running at the time of a preset Auto Start function, and
Auto Start is activated, the existing operating mode will override the Auto Start function
and the Auto Start will not turn on.
Note: All process Set to Run in Auto Start Mode must be at least one minute long for all
Run Modes (Manual, Timer, and Profile).

Zone Calibration Page
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.
To access the Zone Calibration Page, enter the Setup Mode (see description earlier in
this manual). Press the Page key until Zone Cal is displayed. Press the Menu key. Each
parameter can be changed by pressing the Menu key until the desired parameter is
displayed, and then pressing the keys to change the value.
*Only use when no calibration instrument is available, push key to restore factory
values.
Press the Page key to exit the Zone Calibration Page.
Two points of display calibration (temperature offset) are available. The Zone 1 Actual
and Zone 2 Actual parameters are the two temperature points where the offset is to take
effect. These values are adjustable. The Zone 1 and Zone 2 Displayed parameters are
the values the user wishes to have displayed at the Actual temperatures, and are also
adjustable.
51
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 reads 400°F. In this case operate the
oven in manual mode with a setpoint of 400°F. Record 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.
52
Sensor Calibration Page
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:
53
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
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.
