The controller will cycle three times through a heating and
cooling pattern, measuring the characteristics of the load and
chamber temperature controls. During the auto tuning, At will
alternately flash with the measured temperature
(PV) to indicate
that theauto tuning is in progress. Thelengthof timefor the auto
tune varies with the load, chamber size and temperature selected.
The auto tuneis completed when the regular display of the
measured temperature is shown. The chamber should now
operate to the process temperature with the given product load,
with the quickest response and minimal temperature overshoot.
If the process temperature or load changes significantly, another
auto tune session may be necessary to optimize the chamber
performance.

isilluminated to indicate this program is in the indefinite dwell at
thelast target temperature. This hold indicator is caused by the
" JC " selection of "I", while the " JC " selections of "0" or " 2 " will
not illuminate the 'HLD' (hold) indicator.
6.3.4 Ending a Program
To end a program while in the 'RUN' or 'HLD " (hold) mode,
press and hold the 'UPIRESET' button to turn off the current
program and extinguish the 'RUN' or 'HLD' indicator.
Turning off the unit's power will also stop the program. When

the program menu and return to the reset or standby display.
Auto tuning maximizes the performance of the chamber at a
selected temperature with the product load's characteristics, by
operating with the quickest response and minimal temperature
overshoot.
Factory settings are for general purposes, but your process can be
enhanced through the auto tune feature. To obtain this maximum
performance, follow these steps to auto tune thecontroller.
1. Load the chamber with materials that have the same mass
and thermal characteristics as an actual product load.
2. Operate the chamber to the process temperature.
3. Start the Auto Tune: Press and hold the 'SETtENT' button
for three seconds to display the "modE" parameter of the
Operating Parameter menu.
4. Press and release the 'SETENT' button five times to
advance to the
" At " parameter.
5. Press and release the 'UP' arrow button to show " on " in the
lower display.
6. Press the 'SETtENT' button once to enter the auto tune mode
and exit the Operating Parameters menu.
7. The controller will cycle three times through a heating and
cooling pattern, measuring the characteristicsof the load and
chamber temperature controls. During the auto tuning, 'At'
will alternately flash with the measured temperature (PV)
display to indicate that the auto tuning is in progress. The
length of time for theauto tune varies with theload, chamber
size and temperature selected.
8. Theauto tuneis completed when the regular display of the
measured temperature is shown without the
" At " value
flashing. The chamber should now operate to the process
temperature with the given product load, with the quickest
response and minimal temperature overshoot.
9. If the process temperature or load changes significantly,
another auto tune session may be necessary to optimize the
chamber performance.
To interrupt the auto tunebefore it is completed, simply turn off
the power to the controller and unit. When the power is restored
the auto tune will not be operating.

6.5 TemperatureOffset Procedure
The purpose of this procedure is to create an offset in the
displayed temperature measurement for the Yokogawa model
UP150 temperature controller.
1. Operate the oven chamber to your normal stable temperature
setpoint, with an independent temperature measurement
device located in the center of the chamber. The controller
will be 'running' the program or operating in the local mode
to maintain the temperature.
2. Note any difference in the controller's measured temperature
(upper value) and the independent measurement. If a
differenceof greater than 1°C is noted proceed with the
following steps.
3. Press and hold the
" SETENT " button for 3 seconds to
display "modE".
4. Verify the button lockout parameter will give access to make
thisdisplay offset. Press and release the
" SETENT " button
twelve times to display "LoC". The value 0 (zero) displayed
will give full access and is necessary to make the display
offset changes desired. If the value displayed is 1 or 2, use
the
" down arrow " button to make 0 (zero) and press and
release the
" SETENT " button to register this change.
5. Press and release the
" SETENT " button twelve times to
display "bS" and the current offset value.
6. Select the offset value with the arrow buttons that is needed
to make this controller display correctly.
For example, if the independent measurement is 253"C, the
controllerTemperature measurement display shows 250°C,
and the current controller offset (bS) is - 2, then make the
controller display offset "+I"
[(+3 needed offset) + ( - 2 current offset) = (+1 new offset)].
7. Press and release the " SETENT " button once to register this
new offset value. Press and hold the
" SETENT " button for 3
seconds to exit this controller menu.
8. Operatethecontroller to thesame temperature to stabilize the
chamber to check for any further variations between the
controller and theindependent measurement. Repeat steps
2
- 7 as necessary.
9. This completes the display offset procedure for the
Yokogawa model UP150 temperature controller.If the button
lockout parameter "LOPwas originally on a value of 1 or 2,
repeat steps 3
& 4 to return to this original value.
