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.

Meaning of auto-tuning (AT) start in auto-tuning Group(G.At) is as follows:
1 is auto-tuning for SV1.
2 is auto-tuning for SV2.
3 is auto-tuning for SV3.
- AUTO proceed with the Auto-tuning in the order of the SV1, SV2, SV3.
 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 8 : Heating / Cooling control
In Heating / Cooling control, it divides the PID computation result into two control signals and outputs
to heating and cooling output terminals. The control method for each heating and cooling can be
selected either PID control or ON/OFF control. Also, it is possible to choose one of the control outputs:
relay output, SSR, and current output as the heating output and cooling output.
Also, the dead band of “-” set value and the dead band of PID control for both heating and
cooling are shown as below. At this time, there is an overlapped output from the both terminals.

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).

When select ON in Zone of control group(G.CtL) and set the location of temperature in n.rP
of PID group(G.PID), that distinguishes Zone 1, Zone 2, Zone 3.
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.
