2.1 GENERAL NOTES ABOUT WIRING
1. Do not run input wires together with power cables.
2. External components (like zener barriers, etc.) connected
between sensor and input terminals may cause errors in
measurement due to excessive and/or not balanced line
resistance or possible leakage currents.
3. When a shielded cable is used, it should be connected at
one point only.
4. Pay attention to the line resistance; a high line resistance
may cause measurement errors.

5. CONFIGURATION PROCEDURE
5.1 INTRODUCTION
When the instrument is powered, it starts immediately to work
according to the parameters values loaded in its memory.
The instrument behaviour and its performance are governed
by the value of the stored parameters.
At the first start up the instrument will use a “default”
parameter set (factory parameter set); this set is a generic
one (e.g. a TC J input is programmed).
WARNING! Before connecting the output actuators,
we recommend to configure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).
To change these parameters you need to enter the
“Configuration mode”.
5.2 INSTRUMENT BEHAVIOUR AT
POWER ON
At power ON the instrument can start in one of the following
mode depending on its configuration:
Auto mode
–The upper display shows the measured value;
–The lower display shows the Set point value;
–The decimal figure of the less significant digit of the lower
display is OFF;
–The instrument is performing the standard closed loop control.
Manual mode (OPLO)
–The upper display shows the measured value;
–The lower display shows the power output [preceded by H
(for heating) or C(forcooling)].TheMANLEDislit;
–The instrument does not perform Automatic control;
–The control output is equal to 0% and can be manually
modified by and buttons.
Stand by mode (St.bY)
–The upper display shows the measured value;
–The lower display shows alternately the set point value and
the message St.bY or od;
–The instrument performs no control (the control outputs
are OFF);
–The instrument is working as an indicator.
We define all the above described conditions as
“Standard Display”.
5.3 HOW TO ENTER THE
“CONFIGURATION MODES”
Note: The TC10 is equipped with two different “configuration”
methods:
A) The “code” configuration method;
B) The “complete” configuration method.
The “code” configuration method is really fast but modifies
only the most common configuration parameters.
The “complete” configuration method allows to take
advantage of all instrument features, giving more capabilities
it requires more actions and time.
Note that you can take advantage by both methods because if
you use the code configuration and then you enter in the
complete configuration, all selections made by code are still valid.
In both cases the instrument have one complete parameter set.
We call this set “configuration parameter set” (or
“configuration parameters”).
When code configuration method is used all the parameters
not modified by the code will maintain their default values.
In both cases the access to the configuration parameters is
protected by a password (a specific password for each method).
Note: The instrument will show only the parameters consis-
tent with the specific hardware and in accordance with
the value assigned to the previous parameters
(e.g.: if you set an output as “not used” the instrument
will mask all other parameters related to this output).
5.3.1 “Code” configuration procedure
The controller configuration (Input type, Control mode, etc.)
can be made entering two 4-digit codes.
Before to enter into code configuration we suggest you to
prepare the two codes according to the tables that follow.
Notes: 1. During the Code configuration procedure there is
no timeout.
2. To leave, at any time, the Configuration session
without
saving the settings made, press the
button.
To enter into code configuration proceed as follows:
1. Push the button for more than 3 seconds.
The upper display will show PASS (flashing) while the
lower display will show 0;
2. Using and buttons set the password programmed
inparameter[120]PAS4. The factory default password
for Code configuration is 300;
3. Push the button;
If the password is correct the instrument will show one of
the following conditions:
• If no code is present, the display shows codE on the
upper display and oFF on the lower display.
Push the button to continue.
The upper display will flash cod1 while the lower display
shows 0000.
• If a previous code was stored, the upper display will
flash cod1 while the lower display shows the value of
cod1 stored in memory.

8. Push the button to save the configuration code and
exit the Code configuration procedure.
Note: After using the “Code configuration” method, it will
always be possible to modify the parameters using the
“Complete configuration” method. If the value of a
parameter among those included in the configuration
codes (cod1 - cod2) gets modified, the instrument
will acquire the change while maintaining all the other
parameters.
WARNING! After a parameter change made as described
in the previous “Note”, when retrieving the
configuration codes (cod1 - cod2), the lower
display will show “oFF” to alert the operator that
one of the parameters has been changed.

Yokogawa Electric Corporation - TC10 - ENGINEERING MANUAL - PAG. 8
5.3.2 Complete configuration procedure
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (e.g.: control, alarms, output functions).
1. Push the button for more than 3 seconds. The upper
display will show PASS while the lower display will show 0.
2. Using and buttons set the programmed password.
Notes: 1. The factory default password for configuration
parameters is equal to 30.
2. During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration chan-
ge can produce a heavy bump to the process, it is
advisable to temporarily stop the controller from
controlling during the programming procedure
(control output will be OFF).
Apasswordequalto2000+theprogrammed
value(e.g.2000+30=2030).
The control will restart automatically when the
configuration procedure will be manually closed.
Push the button
If the password is correct the display will show the acronym
of the first parameter group preceded by the symbol: ] .
In other words the upper display will show: ]inp
(group of the Input parameters).
The instrument is in configuration mode.
5.4 HOW TO EXIT THE “CONFIGURATION
MODE”
Push button for more than 3 seconds, the instrument will
come back to the “standard display”.
5.5 KEYBOARD FUNCTIONS DURING
PARAMETER CHANGING
A short press allows to exit from the current parameter
group and select a new parameter group.
A long press allows you to close the configuration
parameter procedure (the instrument will come back
to the “standard display”).
When the upper display is showing a group and the
lower display is blank, this key allows to enter in the
selected group.
When the upper display is showing a parameter and
the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Allows to increase the value of the selected parameter.
Allows to decrease the value of the selected parameter.
+ These two keys allow to return to the previous
group. Proceed as follows:
Push the button and maintaining the pressure,
then push the button; release both the buttons.
Note: The group selection is cyclic as well as the selection
of the parameters in a group.
5.6 FACTORY RESET - DEFAULT
PARAMETERS LOADING PROCEDURE
Sometime, e.g. when you re-configure an instrument
previously used for other works or from other people or when
you have made too many errors during configuration and
you decided to re-configure the instrument, it is possible to
restore the factory configuration.
This action allows to put the instrument in a defined
condition (the same it was at the first power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds. The upper
display will show PASS while the lower display shows 0;
2. Using and buttons set the value -481;
3. Push button;
4. The instrument will turn OFF all LEDs for a few seconds,
then the upper display will show dFLt (default) and then
all LEDs are turned ON for 2 seconds. At this point the
instrument restarts as for a new power ON.
The procedure is complete.
Note: The complete list of the default parameters is available
in Appendix A.
5.7 CONFIGURING ALL THE PARAMETERS
In the following pages we will describe all the parameters of
the instrument. However, the instrument will only show the
parameters applicable to its hardware options in accordance
with the specific instrument configuration (i.e. setting AL1t
[Alarm1type]tononE[notused],allparametersrelatedto
alarm 1 will be skipped).

]LbA group - Loop break alarm
General note about LBA alarm
The LBA operate as follows: applying the 100% of the power
output to a process, the process variable, after a time due to the
process inertia, begins to change in a known direction (increases
for an heating action or decreases for a cooling action).
Example: If I apply 100% of the power output to a furnace,
the temperature must go up unless one of the component in
the loop is faulty (heater, sensor, power supply, fuse, etc.)
The same philosophy can be applied to the minimum power.
In our example, when I turn OFF the power to a furnace, the
temperature must go down, if not the SSR is in short circuit,
the valve is jammed, etc..
LBA function is automatically enabled when the PID requires
the maximum or the minimum power.
When the process response is slower than the programmed
limit the instrument generates an alarm.
Notes: 1. When the instrument is in manual mode, the LBA
function is disabled.
2. When LBA alarm is ON the instrument continues
to perform the standard control. If the process
response comes back into the programmed limit,
the instrument automatically resets the LBA alarm.
3. This function is available only when the programmed
control algorithm is equal to PID (Cont = PID).
[52] LbAt - LBA time

[54] LbAS - Delta measure used by loop break
alarm (loop break alarm step)
Available: When[52]LbAtisdifferentfromoFF.
Range: 1 to 9999 engineering units.
[55] LbcA - Condition for LBA enabling
Available: when[52]LbAtisdifferentfromoFF.
Range: uP = Enabled when the PID requires the maxi-
mum power only;
dn = Enabled when the PID requires the mini-
mum power only;
both = Enabled in both condition (when the PID re-
quires the maximum or the minimum power).
LBA application example:
LbAt (LBA time) = 120 seconds (2 minutes);
LbAS (delta LBA) = 5°C.
The machine has been designed in order to reach 200°C in
20 minutes (20°C/min);
When the PID demands 100% power, the instrument starts
the time count.
During time count if the measured value increases more
than 5°C, the instrument restarts the time count. Otherwise
if the measured value does not reach the programmed delta
(5°C in 2 minutes) the instrument will generate the alarm.

[57] Auto - Auto tune selection
There are three auto-tune algorithms:
• Oscillating auto-tune;
• Fast auto-tune;
• EvoTune.
1. The oscillating auto-tune is the usual auto-tune and:
• It is more accurate;
• Can start even if PV is close to the set point;
• Can be used even if the set point is close to the
ambient temperature.
2. The fast type is suitable when:
• The process is very slow and you want to be opera-
tive in a short time;
• When an overshoot is not acceptable;
• In multi loop machinery where the fast method reduces
the calculation error due to the effect of the other loops.
3. The EvoTune type is suitable when:
• You have no information about your process;
• You can not be sure about the end user skills;
• You desire an auto tune calculation independently
from the starting conditions (e.g. set point change
during tune execution, etc).
Note: Fast auto-tune can start only when the measured
value(PV)islowerthan(SP+1/2SP).

[67] rcG - Power ratio between heating and
cooling action (relative cooling gain)
The instrument uses the same PID parameter set for heat
and for cool action but the efficiency of the two actions are
usually different.
This parameter allows to define the ratio between the efficiency
of the heating system and the efficiency of the cooling one.
An example will help us to explain you the philosophy.
Consider one loop of a plastic extruder. The working
temperature is equal to 250°C.
When you want to increase the temperature from 250 to 270°C
(DT = 20°C) using 100% of the heating power (resistor), you
will need 60 seconds.

Yokogawa Electric Corporation - TC10 - ENGINEERING MANUAL - PAG. 17
On the contrary, when you want to decrease the temperature
from 250 to 230°C (DT = 20°C) using 100% of the cooling
power (fan), you will need 20 seconds only.
Inourexampletheratioisequalto60/20=3([67]rcG=3)
and it say that the efficiency of the cooling system is 3 time
more efficient of the heating one.

Range: 1.0 to 130.0 seconds.
[69] rS - Manual reset (integral pre-load)
It allows to drastically reduce the undershoot due to a
hot restart. When your process is steady, the instrument
operates with a steady power output (e.g.: 30%).
If a short power down occurs, the process restarts with a
process variable close to the set point while the instrument
starts with an integral action equal to zero.
Setting a manual reset equal to the average power output (in our
example 30%) the instrument will start with a power output equal
to the value it will use at steady state (instead of zero) and the
undershoot will become very little (in theory equal to zero).
Available: When[56]cont=PID.
Range: -100.0to+100.0%.
[72] od - Delay at power up
Available: When at least one output is programmed as
control output.
Range: oFF: Function not used;
0.01 to 99.59 hh.mm.
Notes: 1. This parameter defines the time during which
(after a power up) the instrument remains in stand
by mode before to start all other function (control,
alarms, program, etc.).
2. When a program with automatic start at power up
and od function are programmed, the instrument
performs od function before to start the program.
3. When an auto-tune with automatic start at power
up and od function are programmed, the autotune
will start at the end of od delay.
[73] St.P - Maximum power output used during

2. When St.P parameter have a negative value, the
limit will be applied to the cooling output(s) only.
3. When a program with automatic start at power
up and soft start function are programmed, the
instrument performs the soft start and than the
program function.
4. The auto-tune function will be performed after
soft start function.
5. The Soft start function is available also when ON/

set as a Master while the other are (as usual) Slave units. The
Master unit can send his operative set point to the slave units.
In this way, for example, is possible to change simultaneously
the set point of 20 instruments by changing the set point of the
master unit (e.g. hot runner application).
SP.rt parameter defines how the slaves units will use the value
coming from serial link.
