4.2 Wiring examples

Caution• Use a thermocouple, compensating lead wire and 3-wire system RTD in accordancewith the sensor input specifications of this controller.
• This controller has neither a built-in power switch, circuit breaker nor a fuse.
Therefore, it is necessary to install them in the circuit near the external controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• With the relay contact output type, externally use an auxiliary electromagnetic
switch according to the capacity of the load to protect the built-in relay contact.
To prevent the unit from harmful effects of unexpected high level noise, it isrecommended that a surge absorber be installed between the electromagnetic
switch coils.
• When wiring, keep input wire (thermocouple, RTD, etc.) away from AC source
and load wire to avoid external interference.
• Use a thick wire for the ground (1.25 to 2.0mm2)• Do not apply a commercial power source to the sensor connected to the input
terminal nor allow the power source to come into contact with the sensor.

Check that settings are applicable for the users’ conditions, referring to “5.2 Setup” (p.16)
and “5.3 Data logging condition setting” (p.21).
6.1 Input set values and run the LCD-13A.
(1) Turn the power supply to the LCD-13A ON.
Turn the power supply to the LCD-13A ON.
After the power to the controller is turned on, CH1 PV display indicates “” forapprox. 4 seconds.
During this time, all outputs and LED indicators are in OFF status.
After that, the PV display indicates sensor input value and the SV display indicatesthe SV, and control starts.
(2) Input set values.

If necessary, perform Sensor correction (p.32, 33) and AT (auto-tuning) (p.33 – 36).
6.2 Preparation for data logging
CF card included
Media: Type I (Thickness 3.3mm), Maximum capacity 256MB
Format: FAT16
Writing method: Writing in a new file (Opens a new file every time logging
starts, and saves data in it.)
CF card memory usage: When logging all items with data logging cycle 5 seconds,
1.7 to 2.0MB of the CF card can be used every 24 hours.
Data reliability when power failure occurs during data logging
The set data of the LCD-13A is backed up in the non-volatile IC memory.
The time it takes between detecting power failure and turning the power to the
LCD-13A off is approx. 260mS for 85V AC and 4 seconds for 264V AC.
For the CF card included, writing time is 200ms and closing process time is 40mS.
Thus total time is 240mS. Writing and closing of the CF card can be finished within
Shinko controllers’ power failure process time. Therefore data reliability can be
maintained.
If any other CF cards (commercially available) are used, the data reliability is notguaranteed.

6.3 How to start data logging
There are 2 ways to start data logging. One is with the LOG key, and the other is by theexternal operation input.
Data logging start with the LOG key
Press the LOG key.
Data logging starts on the conditions which have been set during the Data logging
condition setting mode.
The LOG indicator is lit during data logging, and flashes while writing to the CF card.
Data logging start using the external operation input
Connect LOG terminals 19 and 20 (Contact Closed).
If the external operation (LOG) input is ON during auto-start, logging will continue even
if the logging end time has expired.
Logging stops when external operation (LOG) input is OFF.
Even if logging is within its time, logging stops if the external operation (LOG) input isturned from ON to OFF.
Data logging starts on the conditions which have been set during the Data logging
condition setting mode.
The LOG indicator is lit during data logging, and flashes while writing to the CF card.
CF card file
Every time the LCD-13A starts data logging, LCD-13A writes the data in a new file.
When logging data reaches 65,000 lines, the file is closed and a new file is opened fordata writing.
The file is named as shown below.
yymmdd_hhmmss.CSV
yy : Lower 2 digits of the year (2003: 03)
mm : Month (January: 01)
dd : Day (the 1st : 01)
hh : Hour (8 a.m.: 08, 8 p.m.: 20)
mm : Minutess : Second
For example, if data logging is started at 8:30 a.m. on January 1st, 2003,
the file will be named as “030101_083000.CSV”.
Limit of number of files
A maximum of 170 files can be saved in the CF card. If the number of files exceeds 170,an error message
appears on the CH1 PV display regardless of the remaining
capacity in the CF card.
Power failure during data logging
If power failure occurs during data logging, data is automatically saved in the file.
After the power is restored, data logging is stopped.
However, if external operation (LOG) input terminals 19 and 20 are connected (Contact
Closed), data logging automatically resumes, and writes the data in a new file.
If momentary power failure occurs while writing to the CF card, one batch of data
logging might be lost.

29

6.4 How to stop data logging
There are 2 ways to stop data logging. One is with the LOG key, and the other is by theexternal operation (LOG) input.

6.8 How to correct PV (Sensor correction function)[Sensor correction function]
This corrects the input value from the sensor. When a sensor cannot be set at alocation where control is desired, the sensor measuring temperature may deviate fromthe temperature in the controlled location.
When controlling with multiple controllers, the accuracy of the sensors or dispersion ofload capacity has influence on the control.
Therefore, sometimes the measured temperature (input value) does not concur withthe same set value.
In such a case the control can be set at the desired temperature by correcting the input
value of the sensors.
PV = Current actual temperature + (Sensor correction value)

6.9 How to perform AT (auto-tuning)
In order to decide each value of P, I, D and ARW automatically, the auto-tuning
process should be made to fluctuate to obtain an optimal value.

Notice• Perform AT (auto-tuning) during the trial run.
• During AT (auto-tuning), none of the setting items can be set.
• If power failure occurs during AT (auto-tuning), the tuning stops.

[If P, I, D, ARW values cannot be changed]• If AT (auto-tuning) does not finish in 4 hours after it starts, PID auto-tuning iscancelled automatically, and P, I, D, ARW values return to the value set before theauto-tuning was performed. In this case, set P, I, D, ARW values manually.
• If AT (auto-tuning) is cancelled during the process, P, I, D, ARW values return tothe value set before the auto-tuning was performed.
6.10 Auto-reset (offset correction)
Auto-reset is performed to correct the offset at the point at which PV indication isstabilized within the proportional band during the P or PD action.
Since the corrected value is internally memorized, it is not necessary to performthe auto-reset again as long as the process is the same.
However, when the proportional band is set to 0, the corrected value is cleared.

7. Control and Alarm action
7.1 P, I, D and ARW(1) Proportional band (P)Proportional action is the action during which the control output varies in proportion
to the deviation between the SV (main set value) and the PV (processing temperature).
If the proportional band is narrowed, even if the output changes by a slight variationof the processing temperature, better control results can be obtained as the offset
decreases.
However, if the proportional band is narrowed too much, even slight disturbances
may cause variation in the processing temperature, control action changes to
ON/OFF action and the so-called hunting phenomenon occurs.
Therefore, when the processing temperature comes to the balanced position near
the SV and a constant temperature is maintained, the most suitable value isselected by gradually narrowing the proportional band while observing the control
results.
(2) Integral time (I)Integral action is used to eliminate offset. When the integral time is shortened, thereturning speed to the set point is accelerated. However, the cycle of oscillation is also
accelerated and the control becomes unstable.
(3) Derivative time (D)Derivative action is used to restore the change in the processing temperatureaccording to the rate of change. It reduces the amplitude of overshoot and undershootwidth.
If the derivative time is shortened, restoring value becomes small, and if the derivative
time is set longer, an excessive returning phenomenon may occur and the control
system may be oscillated.
(4) ARW (Anti-reset windup)
ARW (Anti-reset windup) prevents overshoot caused by the integral action. The smaller
the ARW value, the less the overshoot caused by the integral action in the transition
status, however it takes time until stabilization.
When setting ARW manually, set it to the closest MV (manipulated variable) when thecontrol is stabilized.

No response• Response with data
When the host computer sends the reading
command, the LCD-13A responds with thecorresponding set value or current status.
• Acknowledgement
When the host computer sends the settingcommand, the LCD-13A responds by sending
the acknowledgement after the processing isterminated.
• Negative acknowledgement
When the host computer sends a non-existentcommand or value out of the setting range, theLCD-13A returns a negative acknowledgement.
• No response
The LCD-13A will not respond to the host computerwhen the global address is set, or when framing error
or checksum error is detected.

Communication timing of the RS-485
LCD-13A side
When the LCD-13A starts transmission through the RS-485 communication line, theLCD-13A is arranged so as to provide an idle status (mark status) transmission period of
1 or more characters before sending the response to ensure the synchronization on thereceiving side.
The LCD-13A is arranged so as to disconnect the transmitter from the communication line
within a 1 character transmission period after sending the response.
Host computer side (Notice on programming)
Set the program so that the host computer can disconnect the transmitter from thecommunication line within a 1 character transmission period after sending thecommand in preparation for reception of the response from the LCD-13A.
To avoid the collision of transmissions between the host computer and the LCD-13A, send
the next command after carefully checking that the host computer received the response.
Note:
When the host computer communicates with the LCD-13A through thecommunication converter (IF-400), make sure that the program is appropriate for thetransmission timing.

9.5.3 Checksum calculation
Checksum is used to detect receiving errors in the command or data.
Set the program for the host computer side as well to calculate the checksum of the
response data from the LCD-13A so that the communication errors can be checked.
The ASCII code (hexadecimal) corresponding to the characters which range from theaddress to that before the checksum is converted to binary notation, and the total value iscalculated.
The lower 2 digits of the total value are converted to 2’s complements, and then tohexadecimal figures, that is, ASCII code for the checksum.
Refer to the following example procedure.
Checksum calculation example
CH1 SV1: 600 (0258H)
Address (instrument number): 0 (20H)• 1’s complement: Reverse each binary bit. 0 will become 1 and vice versa.

Notes on the setting command and reading command• If is possible to set the value with the setting command of the communication function
even when the set value is locked.
• Although the options are not applied, setting the items for the options is possible by thesetting command. However, they will not function.
• The memory can store up to 1,000,000 (one million) entries.
If the number of settings exceeds the limit, the data will not be saved. So frequenttransmission via communication is not recommended.
• When connecting plural LCD-13A units, the address (instrument number) must not be
duplicated.
47

• When sending a command by Global address 95 (7FH), the same command is sent to
all the LCD-13A units connected. However, the response is not returned.
• The instrument number and communication speed cannot be set by communication.
Setting command• The settable range is the same as that by keypad operation.
For the communication command, refer to the communication command table of this manual.
• All commands are composed of ASCII.
• The data (set value, decimal) is converted to hexadecimal figures, and ASCII is used.
A negative number is represented with 2's complement. When the data (set value) has
a decimal point, a whole number without a decimal point is used.
Reading command• All commands are composed of ASCII.
• The data (set value, decimal) is converted to hexadecimal figures, and ASCII is used.
A negative number is represented by 2's complement. When the data (set value) has adecimal point, the response is returned as a whole number without a decimal point.

9.6 Communication command table
When the data (set value) has a decimal point, remove the decimal point and represent it
as a whole number, then express it in hexadecimal figures.

Logging auto-start function
If Logging auto-start “Effective” is selected during Logging auto-start selection,
auto-start start time and end time can be set, and logging can be performed within the settime.
If logging auto-start start time and end time are set to the same value, logging continues
until power-off or until CF card capacity is exceeded. Next time the power to the unit isturned on again, logging auto-start begins.
When the power is restored, logging auto-start begins within the set time dependingon the logging start time and end time.
During auto-start, usual logging can start or stop.
If External operation (LOG) input is ON during auto-start, logging will continue even if
logging end time has elapsed.
When external operation (LOG) input is OFF, logging stops.
If external operation (LOG) input is turned from ON to OFF, logging stops even within

Presumed cause and solution• The thermocouple or RTD input may be burnt out.
How to check whether the sensor is burnt out[Thermocouple]
If the input terminal of the instrument is shorted, and if
approximate room temperature is indicated, the instrument
is likely to be operating normally, however, the sensor may
be burnt out.
[RTD]
If approx. 100 resistance is connected to the input
terminals between A-B of the instrument and between B-B
is shorted, and if a value around 0 (32 ) is indicated,
the instrument is likely to be operating normally, however,the sensor may be burnt out.
• Check whether the input terminal of thermocouple or RTD issecurely mounted to the instrument terminal.
• Check whether polarity of thermocouple or compensating
lead wire is correct.
• Check whether codes (A, B, B) of the RTD agree with the
instrument terminal.
• Check whether sensor specification is proper.
• Check whether the sensor input and temperature unit ( or) setting are correct.
Set the sensor type which is the same as users’ andthe temperature unit during Sensor selection [].
(p.18)
Set the sensor input and the temperature unit properly.
• Sensor correcting value is unsuitable.
Set it to a suitable value.
Set the value properly during Sensor correction setting] in Auxiliary function setting mode 1.
[(p.26, 32, 33)• AC may be leaking into the sensor circuit.
Use an ungrounded type sensor.
• There may be equipment that interferes with or makes
noise near the controller.
Keep equipment that interferes with or makes noise awayfrom the controller.
• Internal memory is defective.
