The waiting action turns off the

operation until a stable state is
reached.

Description of Parameters
This section describes the parameter functions specific to the UT130 temperature controllers.
(The functions described in other sections of this manual and the general functions are not
discussed.)
Parameter
Function
Parameter
Function
Control
mode
Select one from the following:
a. Dynamic auto tune control (SLF) (See note)
b. PID control (PID)
c. On/off control (ONF)
Note: Dynamic auto tune control is not available
for heating/cooling control.
Read the section below this table to find out more
about dynamic auto tune control.
PV input
bias
This function adds a bias value to the measured
input value, and the result is used for display and
control computation.
PV value inside the controller
measured input value
PV bias
+
=
This function is useful for carrying out fine
adjustment when the PV value is within the
required accuracy but it differs from the value
obtained by other equipment.
CTL
BS
Manual
reset
You can set this parameter only for control without
an integral action (when registered as CTL=PID
and I=OFF). The controller outputs the manual
reset (MR) value when PV=SP. For example, if
you set MR=50%, the controller outputs (OUT)
50% when PV=SP.
Maximum/
minimum
value of
target
setpoint
range
Using the SPH and SPL parameters, you can limit
the setting range of the target setpoint (SP) within
the measured input range.
This function prevents SP from being mistakenly
set at too large or too small a value (beyond the
setting range).
MR
SPH,
SPL
Cooling-side
gain
For heating/cooling control, you can set the ratio
between the cooling-side output and heating-side
output.
For example, if you set COL=2.0 and the heating-
side output is 10% at a certain deviation (SP-PV),
then the cooling-side output will be 20% when the
cooling-side also reaches that deviation.
COL
Hysteresis
for
alarm 1
and 2
The alarms are output as relay outputs. Since a
relay has a limited life, excessive on/off actions will
shorten the life of the alarm. To prevent this, you
can set a hysteresis to prevent excessive on/off
actions for both alarm 1 and alarm 2.
Deadband
You can only set a deadband for heating/cooling
control. In a positive deadband, there are neither
heating-side nor cooling-side outputs. In a
negative deadband, there are both heating-side
and cooling-side outputs, which overlap each
other.

SUPER
function
selection
The SUPER function is effective in the following
cases:
a. An overshoot must be suppressed.
b. The rise-up time needs to be shortened.
c. The load often varies.
d. SP is changed frequently.
Note 1: The SUPER function will not work
when on/off control is selected, or I or D
constants is set at OFF in PID control.
Note 2: For some types of systems, the SUPER
function may not be so useful. If this is the
case, turn off the function.
DB
SC
Hysteresis
for
on/off
control
For on/off control (CTL=ONF), you can set a
hysteresis band around the on/off point (SP) to
prevent chattering.

Priority of
PV/SP
display
Since the UT130 controller has a single data
indicator, you can give display priority to either
PV or SP. The data which has the priority will be
displayed on the data indicator upon power-on
or when the operating display is resumed from a
parameter setting display using the
key
(by pressing for at least 3 seconds).
To switch the display between PV and SP,
press the key.

The cycle time is the period of on/off repetitions of
a relay or voltage pulse output in time proportional
PID control. The ratio of the ON time to the cycle
time is proportional to the control output value.

PV input
filter
This function should be used when the PV display
value may fluctuate greatly, for example, when the
measured input signal contains noise. The filter
is of the first-order lag type, and FL sets the time
constant. If a larger time constant is set, the filter
can remove more noise.

■
What is Dynamic Auto Tune Control?
Dynamic auto tune control is one of the features offered by the temperature controller.
When the controller is turned on or the measured input value (PV) starts “hunting”, this mode of
control monitors the behavior of the PV and/or OUT (control output value) to automatically determine
the optimum PID constants. This means that the PID constants may be changed automatically. If this
is not desirable for your system, operate the controller in the normal “PID control”.
If you want to automatically determine the PID constants at the initial startup of the controller, first
define the target setpoint (SP) and then turn the controller off once and then back on again. Do not
use dynamic auto tune control for a system where there is interference or continual disturbances.

IMPORTANT
To use dynamic auto tune control,
(1) be sure to turn on the final control element, such as a heater, before starting the
control, and
(2) make sure the controlled loop is a closed loop.
If you do not follow these precautions, improper PID constants may be written into the
controller. If this occurs, carry out the following:
• Set the parameter CTL at PID.
• Set the PID constants at the factory-set defaults (P = (upper range-limit - lower range-
limit) × 5%; I = 240 sec.; and D = 60 sec.)
• Set the parameter CTL at SLF.
If the control still doesn’t work properly, stop using the dynamic auto tune control
function. Change the parameter CTL setting to PID and execute auto-tuning to obtain
the PID constants.
