communicating personal computer.
Communications Unit No. ( )
When communicating with the host computer, the unit number
must be set in each Temperature Controller so that the host
computer can identify each Temperature Controller. The number
can be set in a range from 0 to 99 in increments of 1. The default
setting is 1. When using more than one Unit, be careful not to
use the same number twice. Duplicate settings will cause
malfunction. This value becomes valid when the power is turned
OFF and ON again.
Baud Rate ( )
Use this parameter to set the speed of communications with the
host computer. It can be set to one of the following values; 1.2
(1200 bps), 2.4 (2400 bps), 4.8 (4800 bps), 9.6 (9600 bps), and
19.2 (19200 bps).
This setting becomes valid when the power is turned OFF and
ON again.
Data Bits ( )
Use this parameter to change the communications data bit length
to7bitsor8bits.
Stop Bits ( )
Use this parameter to change the communications stop bit to 1 or
2.
Parity ( )
Use this parameter to set the communications parity to None,
Even, or Odd.

TROUBLESHOOTING
When an error occurs, an error code will be displayed on the No. 1 display. Check the contents of an error and take appropriate
countermeasures.
No. 1 display
Type of error Countermeasures
Input error Check the wiring of inputs for miswiring, disconnections, short-circuits, and the input
type.
Memory error First, turn the power OFF then back ON again. If the display remains the same, the
Unit must be repaired. If the display is restored, then a probable cause can be external
noise affecting the control system. Check for external noise.
Display range over Though not error, this is displayed when the process value exceeds the display range
when the control range is larger than the display range.
• When less than “-1999”
• When larger than “9999”
HB error First, turn the power OFF then back ON again. If the display remains the same, the
controller must be repaired. If the display is restored, then a probable cause can be
electrical noise affecting the control system. Check for electrical noise.
Note: Error will be displayed only when the display is set for the PV or PV/SP.
Fuzzy Self-tuning
The fuzzy self-tuning (ST) is a function that automatically calculates an optimum PID constant depending on items to be controlled.
FEATURE
The Temperature Controller determines when to execute this fuzzy self-tuning.
FUNCTIONS
SRT: Performs PID tuning according to the step response method when the SP is changed.
LCT: Performs PID tuning according to the limit cycle method when the SP is changed.
Requirements for SRT Functionality
The ST will be executed according to the step response method when the following conditions are satisfied when operation is started or
when the SP is changed.
When operation is started
When SP is changed
1. The SP at the startup is different from the SP at the time the
previous SRT was executed. (See Note.)
2. The temperature upon startup is smaller than the SP in the
reverse operation and larger than the SP in the direct
operation.
3. Restarting of operation is not due to an input error.
Note: The “SP that existed when the previous SRT was
executed” refers to the SP used for obtaining the PID
constant in the previous SRT.
1. The SP after change is different from the SP at the time the pre-
vious SRT was executed. (See Note.)
2. In the reverse operation, the value obtained by deducting the SP
before change from the SP after change is larger than the ST
stable range. In the direct operation, the value obtained by
deducting the SP after change from the SP before change is
larger than the ST stable range.
3. The SP change width is larger than the current proportional band
x1.27+4.
4. The temperature is in the stable state. (It can be in the balanced
state if no output is generated when the power is turned ON.)
If the SP is changed while SRT is being executed and if SRT completion conditions are satisfied, no PID change will take place.
Stabilization State
Measured values remain in the stable range for a certain period
of time.
Balanced State
Output is 0% for 60 seconds and measured values fluctuate
within the width of the stable range.

This inclination is referred to as R.

Precautions
OPERATING ENVIRONMENT
•
Use the Temperature Controller within the rated operating
temperature, storage temperature, and operating humidity
specified for each model.
•
Use the Temperature Controller according to the perfor-
mance specifications such as vibration, shock, and degree of
protection specified for each model.
•
Do not use the Temperature Controller in places where it is
subject to dust or corrosive gases.
•
Install the Temperature Controller away from the devices that
generate high-frequency noise.
SERVICE LIFE
The service life of relays used for the control output or alarm
output varies depending on mostly switching conditions. Be sure
to confirm their performance under actual operating conditions
and do not use them beyond the allowable number of switchings.
If they are used in a deteriorated condition, insulation between
circuits may be damaged and, as a result, the Temperature
Controller itself may be damaged or burned.
The service life of electronic devices such as Temperature
Controllers is determined not only by the number of switchings of
relays, but also by the service life of internal electronic
components. The component service life is affected by the
ambient temperature: the higher the temperature becomes, the
shorter the service life becomes; the lower the temperature
becomes, the longer the service life becomes. For this reason,
the service life can be extended by lowering the internal
temperature of the Temperature Controller.
When two or more Temperature Controllers are mounted
horizontally close to each other or vertically next to each other,
the internal temperature will increase, due to heat radiated by the
Temperature Controllers, and the service life will decrease. In
these situations, forced cooling by fans or other means of air
ventilation will be required to cool down the Temperature
Controllers. When providing forced cooling, however, be careful
not to cool down the terminals solely, to avoid measurement
errors.
ORDERING PRECAUTIONS
Units separately sold, such as Control Output Units and Current
Transformers, are specified for each Temperature Controller. Be
sure to order appropriate units according to the application
requirements.
INSTALLATION
Mounting
Mount the Temperature Controller so that it is horizontally level.
Connection
When extending or connecting the thermocouple lead wire, be
sure to use compensating wires that match the thermocouple
types.
When extending or connecting the lead wire of the platinum
resistance thermometer, be sure to use wires that have low
resistance.
When wiring the platinum resistance thermometer to the
Temperature Controller, keep the wire route as short as possible.
Separate this wiring away from the power supply wiring and load
wiring to avoid inductive or other forms of noise.
Do not use empty terminals.
Crimp Terminal Connection
Use crimp terminals that match M3.5 screws. M3.5 x 8 self-rising
screws are used.
E5GN
7.2 mm max.
Be careful not to tighten the terminals screws excessively.
Soldering Connection
The self-rising screws provide easy soldering connection. Strip
the lead wire by a length of 6 to 8 mm.
OPERATING PRECAUTIONS
For Temperature Controllers with alarm outputs, alarm output
may not be generated correctly when an abnormality occurs in
the device. A separate alarm device should be incorporated into
the system.
To ensure proper performance, parameters of the Temperature
Controllers are set to default values before they are shipped.
Change these parameters depending on actual applications. If
left unchanged, the Temperature Controller will operate under the
default settings.
It takes several seconds for the relay to turn ON from the
moment the power is turned ON. Consider this time when
incorporating Temperature Controllers in a sequence circuit.
When pulling out the Temperature Controller body, do not apply
excessive force. After the body is removed, be careful not to
apply any shock to the connectors or other electronic
components on the PCB.
Models without any specification on their degree of protection or
thosewithIP 0 do not offer a waterproofing feature.
