•

Please make sure to inspect the product if exposed to water, since there is a possibility of electric leakage or a risk of fire.

•

For thermocouple (TC) input, please use a prescribed compensation lead wire. (There will be a temperature error if a general lead is used.)

•

For resistance temperature detector (RTD) input, please use a small resistance of lead wire and the 3 lead wires should

have the same resistance. (There will be a temperature error if the 3 lead wires do not have the same resistance.)

•

Please keep the input signal wire away from the power lines and load lines to avoid the effect of inductive noise.

•The input signal wires and output signal wires should be separated from each other.
If it is not possible, please use shielded wires for the input signal wires.

•For thermocouple (TC), please use ungrounded sensors. (There is a possibility of
malfunction of the product by electric leakage, if a grounded sensor is used.)

•If there is a lot of noise from the power line, installing an insulated transformer or a noise filter
is recommended. The noise filter should be grounded on the panel and the wire between
the output of the noise filter and the power of the instrument should be as short as possible.

•It is effective against noise, if the power lines of the product are made twisted pair wiring.

•Please make sure the operation of the product before using, since the product may not
operate as it intends to if the alarm function is not properly set.

•While replacing the sensor, please turn off the power.

•In case of the high frequent operation, such as proportional operation, please use an auxiliary

•Some parts of this product have limited expected life span and aged deterioration.

•The warranty of this product (including accessories) is
1 year only when it is used for the purpose it was intended to under normal condition.

•When the power is being supplied there should be a preparation time for the contact output. Please
use a delay relay together when it is used as a signal on the outside of interlock circuit or others.

•When the user replaces with a spare unit due to product failure or other reason,
please check the compatibility since the operation can be varied by
the difference of setting parameters even though the model name and code are the same.

•Before using a temperature controller, there could be a temperature difference between

How to set access levels [Level (LEVL)] and a group display [Display (dISP)]

- Setting group configuration parameters are displayed according to the group display
[Display (dISP)] setting.

- Setting group is editable depending on setting Access Level [Level (LEVL)].

Access level [Level (LEVL)]
LEVL 3 :

parameter values can be changed for all setting groups with the key of controller in front.
LEVL 2 : parameter values can not be changed for output group and input group with
the key of controller in front.
LEVL 1 :

parameter values can not be changed for Auto-tuning group(G.At), PID
group(G.PId), Alarm Group (G.ALM), retransmission group(G.trn), communication
group(G.CoM), output group(G.oUt), input group (G.In) with the key of controller in front.

Caution

In the operation mode, if and button are pressed simultaneously for 3 seconds,
it enters setting mode which prevents an operator to change parameter setting as
limiting access to the group. The default is 3rd level. The level setting mode limits the
display setting mode.

Function Description

Function 1 : Auto-tuning

Auto-tuning is a function that the controller automatically measures the characteristics of
the target system and calculates the optimal values for proportional band (P), integral time
(I), and derivative time (D) and then sets the optimal values for each

PID

parameters.
During auto-tuning, the control output is changed to ON/OFF control to get response from
the target system. From the response, the most appropriate

PID

values are obtained for
the system. This is called " Limit Cycle".
HX series has two types of auto-tuning : standard type and low PV type.
① Standard auto-tuning : This auto-tuning is based on the set value (SV).
② Low PV auto-tuning : This auto-tuning is based on the value 10 % lower than the set
value (SV).

If you want to use the auto-tuning, there are 2 ways:

1. When you select the number for set value(SV) you want in start auto-tuning(AT)
of auto-tuning Group(G.At), auto-tuning will start.

2. After selecting auto-tuning(At) in hot-key(Hk.SL) of control group(G.At), auto-tuning will start with
pressing hot-key(SET + UP) in the operation mode of controller for 3 seconds and auto-tuning
will stop with pressing hot-key(SET+UP) for 3 seconds.

Note: When auto-tuning(AT) runs, 'AT indicator' flashes at the front panel.
(When manual output is 'ON', 'AT indicator' lights on steady at the front panel.)

Function 10 : Alarm hold function

If alarm hold function is not set up, low alarm is active when temperature is rising with power ON.
If you select alarm hold function, there is no limit alarm ON during the temperature rise, until set-point.

Note : If you want to use the alarm hold function, please set proper parameter referring to alarm group(G.ALM).

Function 4 : Ramp function

Ramp function Type: A
Select A in Ramp function type (rMP.t) parameters of control group(G.CtL)
The ramp refers to the gradient that reaches the set value (SV), and the setting
method is as follows:

1. Set the desired ramp temperature values in ramp-up and ramp-down temperature settings

2. Set the desired ramp hours or minutes in ramp-time unit setting.
As a result, the gradient of the ramp-up temperature set value / ramp time unit set
value (or ramp-down temperature set value / ramp time unit value) will reach the set
value (SV) from the current temperature.

Ramp function Type : B
Select B in Ramp function type(rMP.t) of control group(G.CtL)
This is similar function with Ramp function type A. except that type B sets time in detail,

0.01~99.59(hh.mm).

Function 2 : PID auto-tuning in Zone

Within the input range, 3 different PID groups can be applied to each of the 3 zones. Since some
systems have a wide range of temperature to control and the optimal P.I.D values are different for
their temperature ranges, this function can be used to apply different optimal PID values to their
temperature ranges.

Function 3 : 2 degree of freedom PID
In order to get better response against disturbance in the steady state, there is usually

a large overshoot in the transient state. To reduce this overshoot in the transient state, 2
degrees of freedom PID control is used while obtaining good disturbance response in
the steady state. The parameter “ALPA” is used to control the amount of overshoot.

Select 2-DOF in control mode(Ctr.M) of control group(G.CtL)
If ALPA = 0%, it's same with previous PID control.
If ALPA = 100%, it may takes long to reach normal state.

Function 12 : Manual output function

If you want to use manual output function, there are 2 ways as follows.

1. Select ON in manual output(MV.Mo) of control group(G.CtL) and current control output amount
converts manual output value. When choose OFF, manual output converts back to auto-output
control.

2. Select manual output function in hot-key(Hk.SL) of control group(G.CtL) and press
hot-key(SET+UP) for 3 seconds at the front panel for manual control output.
When press hot-key(SET+UP)again, manual output converts back to auto-output control.

Note: When auto-tuning(AT) runs, 'AT indicator' flashes at the front panel.
(When manual output is 'ON', 'AT indicator' lights on steady at the front panel.)

Output amount for manual output is adjusted by UP and DOWN key in monitor MV screen.

Function 11 : Hysteresis type

According to selection of Hysteresis type in ON/OFF control, ON/OFF turning point is as follows:
ex) HYS.t: Cntr(center)

- Hysteresis type sets center,

• In heating control, OFF point is SV + HYS/2 and ON point is SV - HYS/2.

• In cooling control, OFF point is SV - HYS/2 and ON point is SV + HYS/2.

ex) HYS.t: EdGE(edge)

- Hysteresis type sets with edge,

• In heating control, OFF point is SV and ON point is SV - HYS.

• In cooling control, OFF point is SV and ON point is SV + HYS.
