1
Before using, please read this (SAFETY INFORMATION) and then use this controller.
It is most important that the instructions in this manual are followed when using this instrument.
Please keep this manual for future reference.
Precautions are classified in WARNING and CAUTION.
WARNING
󱃦 Caution on wiring
● Use an external protection circuit if a fault in the control loop could possibly lead to a serious
problem.
● This instrument do not have a switch for power and a fuse, so please set them if it is needed.
(Fuse rating 250V, 0.5A)
󱃧 Power supply
● Use a rated voltage to prevent damage or trouble.
● To avoid electrical shock or damage, do not turn ON the power until the wiring is completed.
󱃨 Prohibit use in gas atmosphere
Do not use it at a place exposed to combustible or explosive gas.
󱃩 Handling of unit
● To avoid malfunction, electrical shock or fire, this unit must not be disassembled or repaired.
● Do not touch the terminals to avoid electrical shock or malfunction.
󱃪 Caution on maintenance
● Turn OFF the power before mounting or removing the instrument.
● To ensure continuous and safe operation of the instrument, periodical maintenance is
recommended. Some parts are limited in life.
● The warranty period is 1 year only if using in the correct way.
CAUTION
󱃦 Caution on handling
󱅓 Do not install the instrument under any of the following condltions.
● The ambient temperature exceeds 0 ~ 50℃
● The ambient humidity exceeds 20 ~ 90%RH.
● A place where temperature changes suddenly or icing occurs.
● A place exposed to corrosive gas or combustible gas.
● Vibration or shock is likely to be transmitted to the instrument.
● A place exposed to water, oil, chemicals, steam, sunlight.
● A place exposed to much dust, salt or iron.
● A place with much inductive disturbance, static electricity, magnetism noise.
● A place where heat such as radiant heat stays.
WARNING
CAUTION
There is a possibility of death or heavy injury when handling in wrong way.
There is a possibility of injury or physical damage when handling in wrong way.

②Installation
● For NX9, 7, 3 and 2, attach the brackets (2 units) on the fixed halls and tighten with a
screwdriver.
Fixing torque is about 14.7N. cm (1.5kg.cm). NX1 and NX4 has a plastic bracket.
(Care should be taken not to tighten forcedly.)
③Caution on terminal connections
● Use a compensating cable with thermocouple.
● For R.T.D input use a cable which is a small lead wire resistance and without resistance
difference to 3wires.
● To avoid inductive noise to input wires seperate from the power and output wires.
● Keep input wires away from output wires and use shielded wires to earth.
● If the wiring has noise, use the following step: connect a surge absorber to the conductor
coil side if the conductors are connected to the load output, such as the relay contact output.
● Use an insulating transformer with a noise filter when the power suppy has much noise.
● Noise filter should be mounted on a panel which has been earthed and the wiring between
the noise filter output and the instrument power terminals should be shorten.
● It is effective to use a twisted cable for power supply against noise.
● The heater power supply and the instrument power supply should be connected using the
same power suppy when a heater break alarm.
● Time for preparation of contact output is required at power ON. When the output signal is
used for an extenal interlock circuit, connect a delay relay.
④For load circuit connection
● Use an extra relay when the frequency of operation is rather high. In thic case,
SSR output type is Recommended.
• Electromagnetic switch : Proportional cycle time is Min. 30sec
• SSR : Proportional cycle time is Min. 1 sec
• Contact output life : Mechanical : Min. 10 million times (no load)
Electrical : Min. 100 thousand times (rated load)
• SSR drive pulse voltage, DC 4~20mA are not insulated with internal circuit.
Use non-grounded sensor to R.T.D and thermocouple.
⑤For waterproof (Waterproof type)
The instrument has IP65. Use rubber packing when installing the instrument to panel.
Please attach the rubber in correct way.
⑥Caution on key operation / trouble
● If alarm function is not set correctly, alarm output can not be operated at a trouble.
Be sure to check the alarm operation.
● If the input cable is disconnected, the display shows“ ”.
When replacing the sensor, please turn OFF the power supply.
⑦Other
Do not use organic solvents such as alcohol, benzine when cleaning. (Use neutral detergent)
This instrument has process-value (PV) and set-value (SV) each 4 digits with 7 segment FND. This
instrument is divided Recorder and Recorder with Controller.
Function and feature : Group P.I.D, Universal-input (19 types), Universal-output (Relay, SSR, 4~20mA),

When setting,“Input type selection number” must be selected in the input type selection
mode and also“Output type selection number”must be selected in the output type selection
mode before moving to other mode.
If not, data of other group will be changed to prior value.
CAUTION
Output is selectable from Relay, SSR and Current(4~20mA DC)

mode and also“Output type selection number”must be selected in the output type selection
mode before moving to other mode.

CAUTION
① Input type selection
After power ON and when PV is indicating, press key for 3 sec to be displayed at
PV and 3 at SV. (If it is not indicated 3, set again in the level setting mode)
Control group is indicated when press key once more. At the time, input group is indicated
when press key and then“Input type and range selection is shown at SV when press .
At this time the input and range is selected by or key. Press key to confirm
③ Decimal point
Parameter is not indicated in T.C and R.T.D input, but when selecting voltage input“Decimal
point”mode is indicated. (set 1 : 0.0, set 2 : 0.00, set 3 : 0.000)
④ Maximum and Minimum on scale
It is the same function as Maximum and Minimum Range setting when R.T.D or thermocouple
input. This mode is indicated when voltage input ( 30, 31, 32, 33 )
⑤ PV filter
When PV value becomes unstable due to effects of noise, the filter helps suppress the unstable
status. (Range: OFF or 1~120sec. initial value: OFF)
⑥ PV bias
Use this function to adjust PV value in cases where it is necessary for PV value to agree with
another recorder or indicator, or when the sensor cannot be mounted in correct location.

3) RAMP FUNCTION
It is a rate of set value to arrive to set value
according to setting temperature and time.

you can see a temperature with zooming as soon as you
select ON. The tenperature will be in center of paper.

b) LOW PV TYPE AUTO-TUNING
The Auto tuning function automatically measures,
computes and sets the optimum Proportional band(P),
Integral time(I), and Deri-vative time(D). When Auto-tuning,
the controller performs ON/OFF
control and determine proper P.I and D. (Limit cycle type)
RT9-1 series controller have two types of Auto-tuning as
below.
󱃦Standard type auto-tuning :
This type is based on set point value (SV)
󱃧Low PV type auto-tuning :
This type is based on the value 10% lower than
the set point value (SV)
2) Auto-tuning in Zone PID
Zone PID automatically sets PID group in accordance
with a measured value. In Zone PID, auto-tuning sets
the proper PID value by recognizing a mid-value of
reference point as set point value.

5) FUZZY CONTROL
Fuzzy control eliminates overshoot using Fuzzy Logic.
Employing Fuzzy control and Auto-tuning, the
controller effectively control as below.
󱃦When the controller starts control at the position
