7.3.5 Changing a Program
To make changes ONLY to the target temperature and
segment length times for simple program operation, follow
these steps:
1.
Make sure the indicators beside "RUN" and "L" on the
controller face are off. If either indicator is on, press and hold
the 'SET/ENT' button until the display shows 'modE'. Select
‘rES’ in the lower display with the 'arrow' buttons. Press and
release the 'SET/ENT' button once.
2.
Press the 'SET/ENT' button for 3 seconds to display "modE" in the
upper display and "rES" in the lower display. Press and release
‘SET/ENT' repeatedly to display "LoC". Make sure the value
below "LoC" is "0" (zero). If it is not "0", use 'DOWN' arrow to
select "0" and press and release "SET/ENT" button to register the
change to "0".
3.
Press and release the ‘SET/ENT’ button once to show "PrG" on
the upper display.
4.
Press the ‘UP’ arrow to make the lower value "1".
5.
Press and release ‘SET/ENT' button twice to display "SP1". Using
the arrow buttons to revise the target setpoint.
6.
Press and release ‘SET/ENT' button twice to display "tm1". Using
the arrow buttons to revise the segment time length needed to get
to the target setpoint ‘SP1’.
7.
Press and release ‘SET/ENT' button to display other setpoints
and segment time lengths. Use the arrow buttons to change the
temperature setpoints and time lengths. Press and release the
'SET/ENT' button to register any new values,
8.
Press and HOLD the ‘SET/ENT’ button for 3 seconds to exit the
program menu and return to the reset or standby display.
7.4 Auto Tuning the UP150 Controller
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 the
controller.
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 'SET/ENT' button for
three seconds to display the "modE" parameter of the
Operating Parameter menu.
4. Press and release the 'SET/ENT' 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 'SET/ENT' 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 characteristics of 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 the auto tune varies with the load, chamber size and
temperature selected.
8. The auto tune is 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 tune before 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.
7.5 Temperature Offset Procedure
The purpose of this procedure is to create an offset in the
displayed temperature measurement for the Yokogawa model UP
I 50 temperature controller.
1. Operate the oven or furnace 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 difference
of greater than 1oc is noted proceed with the following steps.
3. Press and hold the "SET/ENT" button for 3 seconds to display
"modE".
4. Verify the button lockout parameter will give access to make this
display offset. Press and release the "SET/ENT" 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 "SET/ENT"
button to register this change.
5. Press and release the "SET/ENT" 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 553°C, the
controller Temperature measurement display shows 550°C, and
the current controller offset (bS) is -2, then make the controller
display offset "+I" [(+3 needed (-2 current offset)= (+1
new offset)].
7. Press and release the "SET/ENT" button once to register this new
offset value. Press and hold the "SET/ENT" button for 3 seconds
to exit this controller menu.
8. Operate the controller to the same temperature to stabilize the
chamber to check for any further variations between the controller
and the independent 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 "LoC" was originally on a value of 1 or 2, repeat steps
3 & 4 to return to this original value.
