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.

5.1 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 fi rst 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 confi gure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).

To change these parameters you need to enter the “Confi gu­ration mode”.

5.2 INSTRUMENT BEHAVIOUR AT POWER
ON

At power ON the instrument can operate in two different
mode according to the value assigned to [34] r.md param­eter [34] r.md equal to 0

(Limit output is de-energized at power on in any cases.)

The output relay is always de-energized (opened) at power­on,even if PV does not exceed SP(A). The output (OUT)
display lamp is lit. If thePV does not exceed SP, after the
confi rming operation, output relay will be energized (closed)
and the output (OUT) display lamp turns off .

5.3 HOW TO ENTER THE
“CONFIGURATION MODES”

The confi guration procedure allows to take advantage of all
instrument features.

The instrument have one complete parameter set.

We call this set “confi guration parameter set” (or
“confi guration parameters”).

The access to the confi guration parameters is
password.

5.3.1 Complete confi guration procedure

The confi guration parameters are collected in various
groups. Every group defi nes all parameters related with a
specifi c 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 confi guration

parameters is equal to 30.

3. Push the button

If the password is correct the display will show the acronym

protected by a

[34] r.md equal to 1(Limit output is de-energized at power on
in any cases.)The state of output relay is energized (closed)
and the output (OUT) display lamp turns off if the PV does
not exceed SP at power-on.

of the fi rst parameter group preceded by the symbol:

In other words the upper display will show:

]inp

]

.

(group of the Input parameters).

The instrument is in confi guration 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 confi guration

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

Yokogawa Electric Corporation - TC10-L - ENGINEERING MANUAL - PAG. 5

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-confi gure an instrument
previously used for other works or from other people or when
you have made too many errors during confi guration and
you decided to re-confi gure the instrument, it is possible to
restore the factory confi guration.

This action allows to put the instrument in a defi ned
condition (the same it was at the fi rst 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

display will show PASS while the lower display shows 0;

2. Using

3. Push

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 specifi c instrument confi guration (i.e. setting AL1t
[Alarm 1 type] to nonE [not used], all parameters related to
alarm 1 will be skipped).

[24] HAL1 - Alarm 1 hysteresis

Available: When [19] AL1t is diff
Range: 1 to 9999 engineering units.

Notes: 1.

The hysteresis value is the difference between
the Alarm threshold value and the point the Alarm
automatically resets.

2. When the alarm threshold plus or minus the
hysteresis is out of input range, the instrument
will not be able to reset the alarm.

Example: Input range 0 to 1000 (mBar).

– Set point equal to 900 (mBar);

– Deviation low alarm equal to 50 (mBar);

– Hysteresis equal to 160 (mBar) the theoretical reset point is

900 - 50 + 160 = 1010 (mBar) but this value is out of range.
The reset can be made only by turning the instrument
OFF, removing the condition that generate the alarm and
then turn the instrument ON again;

– All band alarms use the same hysteresis value for both

thresholds;

– When the hysteresis of a band alarm is bigger than the

programmed band, the instrument will not be able to reset
the alarm.

Example: Input range 0 to 500 (°C).

– Set point equal to 250 (°C);

– Relative band alarm;

– Low threshold equal to 10 (°C);

– High threshold equal to 10 (°C);

– Hysteresis equal to 25 (°C).

The TC10-L is an FM (both FM3545 and FM3810) approved
limit controller that can be confi gured either as a high limit or
as a low limit controller by a user.
The relay of the output 2 operates in fail-safe mode (relay
de-energized during shutdown condition) and latching mode.
OUT 2 turns OFF (in this document this condition will be
named shutdown) when:
The instrument is confi gured as a high limiter (Hi.Lo = Hi)
and the measured value is greater than limiter threshold
[“SP” parameter] or.
The instrument is confi gured as a low limiter (Hi.Lo = Lo)
and the measured value is lower than limiter threshold.
Out 2 remains OFF until the condition which generated the
shutdown, no longer exists and the Confi rming action (re­arm) has been performed.
During a shutdown (Out 2 is OFF) the upper display will be
red.
Confi rming action (rearm) can be performed in two different
way:

- by pressing the

key [when “diS” parameter is set to
“but”] but it will be accepted only when the condition which
generated the shutdown, no longer exists (EX lamp is OFF)
and the set point is shown on the lower display (see “normal
display” in “Navigation access”)

- by momentarily closing the digital input (by an external dry
contact) [when diS parameter is set to “di”] but it will be ac­cepted only when the condition which generated the shut­down, no longer exists.
We defi ne also that the time duration of the shutdown condi­tion, stored by the instrument, will be the time from Out 2
goes OFF (shutdown start) and the condition that generate
the shutdown no longer exists.
The confi rmation action is not part of this time count.
The time duration of the shutdown condition and max/min
measured values are stored in memory and available for
viewing (see “navigation access”) until the next shutdown
condition occurs.
These informations are lost at power down.

6.3 ACCESS LEVELS AND SPECIFIC

PARAMETERS

The instrument is showing the “standard display”
This instrument is equipped with 3 different access
levels:Level 1 – Operator Mode.(not protected by password)
Level 2 – Operator modify parameter (protected by a pro­grammable password [default 20])
Level 3 – Confi guration parameters mode (protected by pro­grammable password [default 30])

• The operator area (Level 1) allows: confi rmation
action, to see and to reset the << tim >> parameter
(time duration of the last shutdown condition detected)
and to see and to reset the << Min/max >> (minimum
or maximum measured value during last shutdown
condition detected).

Note: when a new shutdown condition is detected, the

instrument automatically reset << tim>> and << min/
max >> parameters and start to memorize the values
related with the new shutdown condition only. At the
end of the shut down condition, <<tim>> and <<min/
max>> can be read and reset.

• The Level 2 area encompasses the following
