point" to change the ON/OFF point without changing the
Warning
• Before making the connections, turn off this product. Otherwise you may get an electrical shock.
Warnings
• This product will not begin control for about 10 seconds after being turned on. (It will not activate its outputs or other components.) Be careful if you wish to use the product as an interlocking circuit.
• Check the operation manual and other documents to ensure that you make the correct connections for the temperature input terminal, power terminal, and other terminals.
• To connect a resistance bulb to this product, use wiring having a line resistance of no more than
5 per wire.
• To connect a thermocouple to this product, use a specified kind of compensating lead wire or element wire.
• Use a shielded wire if you wish to use this product near a noise source. Do not wire an input/output line in the same duct or conduit tube.
• Separate the input/output signal lines at least 50cm from the power line and load line.
5. Before conducting control
Selecting PID control Selecting ON/OFF control
This product is factory-configured to a "proportional band" of 3.0. This product can conduct control in that state. For better control, however, auto-tune (AT) this product. AT automatically sets settings (values P, I, and D) required for control. For AT, put this product into an actual operating state (a state where the sensor input, control output, and other components are wired). AT takes some time.
This product is factory­If conducting control causes the relay to flutter, increase the sensitivity to reduce the flutter. If conducting control causes this product to stabilize at a level lower than the set temperature, increase the parameter "OFF
setting.

7.5.2 Additional functions
• Standby sequence This function inhibits temperature alarm output even if the conditions are met for temperature
alarm output when this product is turned on. Temperature alarm output is generated only when this product deviates from the conditions for temperature alarm output and satisfies those conditions again. This function is used for bottom temperature alarm output when this product is turned on. This function is enabled when this product is turned on in the shaded portion in
the operation table of temperature alarm outputs. [How to cancel this function] This function is canceled when this product is activated or when either of the following setting is
changed: target, temperature alarm, PV correction, and temperature alarm setting.
• Temperature alarm output holding When a temperature alarm output is generated, this function retains that state. Even if this
product deviates from the conditions for temperature alarm output, the temperature alarm output
will remain on. [How to cancel this function] To cancel this function, turn this product off and back on or disable the additional function for
temperature alarm output setting.

7.9 Communication
7.9.1 What can be done by communication
Communication allows you to read and write data in "Changing settings" and "Reading information" and other items specified in "6. Table of identifiers."
However, reading and writing with ordinary commands are conducted on the RAM inside this product. Turning this product off and back on will restore the written data back to what it was before the writing (the values saved on the EEPROM).
To save written data on the EEPROM of this product, execute the data storage request message (STR).
(See "7.9.10 Communication precautions.")
7.9.2 Pre-communication settings:
Before communication, this product must be set to initial settings for "setting a communication speed" and "setting a unit number."
1) "Setting a communication speed": Set this value with DIP switches.
Use DIP switches 1 and 2. Always turn the 3 and 4 to OFF. Following are the possible combinations.
DIP switch
1 2 3 4

ON
Initial setting: 1: ON, 2 to 4: OFF (9600 bps)
OFF OFF
ON ON
Reserved Reserved
2) "Setting a unit number": Set this value with the rotary switch.
Set a unit number in a hexadecimal number (0 to F). Initial setting: 0 (unit No. 00)
3) "Setting a response delay": Set a time to be taken from the time when a high-level computer
finishes transmitting a "request message" to the time when the line is delivered and this product enters an input state.
• Set range: 0 to 250mS
• Initial value: 0mS
* Notes: An insufficient response delay may result in abnormal communication. Note also
that, in real operations, the processing time of this product will be added to the response delay.
* Caution: Before "setting a communication speed" and "setting a unit number," always
turn off this product.

7.9.9 Code description
n Codes from STX to memory bank function are expressed in ASCII codes. n For the ASCII codes, see "7.9.13. Table of ASCII codes." n For the procedure for conversion to ASCII codes, see communication examples 7.9.11 and
7.9.12.
STX This code is necessary for the receiver to detect the top of a message. This is affixed to the
top of the character string to be transmitted.
Unit number This code is for a higher-level computer to identify the communication partner (this product).
Unit numbers are changed by using the rotary switch.
Set range: 0 to F (to be set in a hexadecimal number) *Before changing a setting, always turn off this product.
Setting channels
This function is for setting channels for reading and writing data in this product. Set range: 1 to 8 (each channel), A (all channels 1 to 8) *Before changing a setting, always turn off this product.
Contents of requests
Enter either of the following codes: R, W, r, or w. R (uppercase, 52H): For reading data from this product W (uppercase, 57H): For writing data in this product or for saving data in this product r (lowercase, 72H): For reading data from the memory bank of this product w (lowercase, 77H): For writing data in the memory bank of this product or for saving data
Identifier An identifier is a classification code (identifier) for data to be read or written and expressed in
a three-digit alphanumerical ASCII code. See "6. Table of identifiers."
Numerical data These are data to be read or written, and are all expressed in five digits regardless of the type.
Negative data: The "-" (minus) sign is in a single digit at the largest digit. Position of the decimal point: 5-digit data does not include a decimal point.
Example: The table below indicates the significances of 5-digit numerical data 00010.
Proportional band (P) →1.0% Data (PV), etc, whose decimal point can be shifted When the decimal point setting (DP) is 0 10 When the decimal point setting (DP) is 0.1 →1.0
ETX This code is needed for the receiver to detect the end of a message. It is affixed to the end of a
character string to be sent (except for BCC).
in this product
Example Significance of the value
24
BCC This is a check code for error detection and is the exclusive OR (EX-OR) of all characters from
STX to ETX.
ACK It is an acknowledge code. If a message received by this product is error-free, this code will be
incorporated in the "response message" from this product and returned.
NAK It is a negative acknowledge code. If a "request message" received by this product is
error-ridden, this code will be incorporated in the "response message" from this product and returned.
If the "request message" received is error-ridden, the error contents ( ERR type) will be
incorporated in the "response message" from this product, following NAK.
ERR type If a "request message" received from this product is error-ridden, the error contents (either of
the numbers in the table below) will be incorporated in the "response message" from this product, following " NAK."
The error number 0 is an instrument error (memory error or A/D conversion error). It will be
incorporated in the "response message" regardless of whether there is an error in the "request message."
The error number 9 is an AT error. It will therefore be incorporated in the "response message"
regardless of whether there is an error in the "request message." Remove the cause of the error immediately and start the AT again.
If there are two or more errors occurring at the same time, the largest error number will be
incorporated.
The table below indicates the error contents and classifications.
Error No.
0 Instrument error (memory error or A/D conversion error) 1 The num erical data deviated from the "range of settings designated specifically with setting
items." 2 The change of requested items is disabled or there are no items to be read. 3 An ASCII code other than numerical data was specified in the field of numerical data. An
ASCII code other than a numerical value or "-" was specified in the field of the highest digit. 4 Format error 5 BCC error 6 Overrun error 7 Framing error 8 Parity error 9 A PV error occurred during AT. Or AT will not end 3 hours later.
Error contents in the "request message" received by this product
Memory bank number Up to eight sets per parameter that can be written in the memory bank can be stored in the
memory bank. This function is to specify which memory bank 1 to 8 is to be used for reading or writing.
• Number of settings: Up to 8 sets
• Set range: 1 to 8
Reading and writing can be done in the memory bank only if the request is "r (lowercase,
72H)" or "w (lowercase, 77H)."

7.9.10 Communications precautions
1) Communications timing Set a sufficient response delay to make sure that this product is switched over from
transmission to reception with regard to a high-level computer in using communications.
See "7.9.3 Communications procedure" and "7.9.2 3) Setting a response delay."
2) Interval between requests In transmitting a series of "request messages" from a high-level computer, allow for an interval
of 1msec or more from the reception of a "response message" from this product to a next transmission.
3) Response conditions This product will not return a "response message" unless it receives a "request message"
containing an STX and ETX (BCC).
If, therefore, the "request message" is error-ridden, this product will not return a "response
message" (error reply) containing a NAK and ERR unless the conditions mentioned above are met.
Therefore, the high-level computer transmits the necessary "request message" again if a
"request message" is sent to this product but the latter does not return a "response message" at the end of an appropriate period.
The moment this product receives an STX, it clears all codes received before that.
4) Errors in unit number specification This product will not respond to any "request message" that specifies a unit number other than
that specified for itself. If, therefore, the a unit number portion of a "request message" is error-ridden, none of the mobile units will return a "response message."
Therefore, the high-level computer transmits the necessary "request message" again if a
"request message" is sent to this product but the latter does not return a "response message" at the end of an appropriate period.
The moment this product receives an STX, it clears all codes received before that.
5) Number of digits in data and the decimal position See "7.9.9 Code description, Numerical data."
6) Operation after receiving a store request message This product starts to store data after correctly receiving a store request message from a
high-level computer.
This product only stores data different from the contents of the EEPROM (data that is
changed). The time (TW) required for storing data is within 2 seconds. This product transmits a storage-complete reply (ACK) when the data is stored. This product will not guarantee that the data is stored if this product is turned off during a
storage operation. Do not turn off this product for 2 seconds after transmitting a store request
message.
7) Operation after turning on the power This product will not perform communications (no response) for about 3 to 5 seconds after it is
turned on. Allow for a delay until communications is started after this product is turned on.
26
8) Storing data other than a store request message
T X A 4 R R V 1 E T X B C C
T X A 4 A C K P V 1 0 0 7 7 7 E T X B C C
Store all parameters in the EEPROM in either of the three cases described below, even if no
store request message is received. If auto-tuning is started and ends normally. (Provided that only PID constants are saved.)
9) Changing the settings (SV or SV2) by communications during auto-tuning Even if the settings (SV or SV2) used in control for auto-tuning are changed by
communications, the settings (SV or SV2) will not be changed until the auto-tuning ends. Note also that memory banks cannot be changed either, during auto-tuning.

Symptom Check item
Inaccurate measurement Is the sensor normal? (Connect a different sensor to the line. Does it show a
similar symptom?) Is the sensor correctly connected? Is the correct sensor type set? (Is the sensor the same as the type setting entered in the product?) Are all the PV correction values set to the correct levels?
The setting does not match the measurement.
Poor control Is the PID value correct? Perform auto-tuning again. Abnormal output
(control/event output) No communication occurs Are the switches SW1 and SW2 set to the correct unit number and
Does the heater have a sufficient capacity? Is the integral time (I) set to the correct setting?
Is the output terminal correctly connected? Is the control type set to the correct setting?
communication speed?
