FUZZY CONTROLLER X
(48)96, 96)96mm)
PYX5,9
DATA SHEET
The PYX is a state-the-art temperature controller offering
enhanced control through the use of fuzzy logic. By employing fuzzy logic the PYX virtually eliminates system
overshoot and effectively supresses fluctuation of the
process variable due to external disturbances. Fuzzy logic
control is the technology of tomorrow offered today.
This controller features universal input/output circuitry and
can accept signals from all thermocouple types, RTD's, and
current/voltage sources. As well, the PYX-5, 9 gives you
the flexibility of choosing such available features as RS-485
communications, analog retransmission, dual output, heater
break alarm, and loop break alarm, to name a few.
FEATURES
1. Incorporation of fuzzy control
An improved response characteristic of controller is
ensured thanks to the fuzzy control exercised while
detecting an overshoot or a difference from the set
temperature value due to a large disturbance.
(Time taken for returning to the set value can be shortened
and temperature variation width can be narrowed.)
2. Universal input
11 kinds of thermocouples, resistance bulbs and voltage/
current inputs is available.
3. Universal output (option)
Relay contact, voltage pulse output for SSR drive and
current output is available on one controller.
The communication protocol conforms either the Fuji
Electric CC data line or Modbus® RTU.
4. Auto/Manual
Change auto-mode to manual-mode and manual operation
can be done using front panel keys.
5. Communication function comprised (option)
Because the general-purpose interface (RS-485) is
mountable, a centralized monitoring/setting system aided
by a personal computer can readily be configured.
6. A wide variety of optional functions
(1) A0 re-transmission (1 point)
A0 is recordable in connection with Fuji's microjet
recorder PHA/PHC.
(2) Programmable alarm (2 points max.)
2 points of alarm action can be registered selected
from 16 kinds.
(3) Dual output
Dual control of heating and cooling operations are
allowed.
(4) Heater break alarm
Use ALM1 or ALM2 output for heater break alarm.
(with function of heater current display, in parameter
" ")
(5) Ramp/soak function
4 ramp/soak-pair patterns are registrable.
(6) External DI function (1 point)
SV (setting value) can be changed a predetermined
value according to external command input (DI).
(7) Remote SV
SV (setting value) can be controlled by external 1 to
5V DC analog input.
7. UL, C-UL approval

(1) Fuzzy feedback control
Fuzzy feedback control expresses the basic actions of
PID control in fuzzy rules and has a nonlinear characteristic
in order to straighten out the problem inherent to PID
control (i.e., overshoot occurs when improving response
or instability arises due to a change in system even when
optimum PID parameters are assigned).
• Comparison of controllability
Each result of fuzzy control and PID control is shown
below.
It is understandable that the overshoot due to a change
of set value has been suppressed in fuzzy control.

(2) Ramp soak function (option)
Function to automatically change the set point value with
elapsing of time, in accordance with the preset pattern,
as shown below. This device allows maximum of 4 ramp
soak programs.
This first ramp starts at the value measured immediately
before the program is executed (PV).

PID control
Remarks: (1) Once auto-tuning has been made, PID parameter values
are retained despite power-off operation. Therefore, autotuning need not be repeated for the subsequent operations.
(2) During auto-tuning, control output corresponds to ON/OFF
action. This may cause PV to change widely depending
on process. If such a change is unallowable, auto-tuning
should not be used.

(3) Do not use the auto-tuning function for a process having
a quick response, such as pressure control, flow control,
etc.

Ramp : Region in which the SP changes toward the

the target value.
Powering on can automatically trigger the program run

can also do that.

The controller incorporates both the heating output and
the cooling output for setting "cooling control cycle", "cooling
proportional band" and "dead band or overlap band".

Remarks:
(1) PID auto-tuning is carried out only on the heating side. During autotuning, output on the cooling side remains turned off. After autotuning, both heating and cooling operations are performed according
to the same PID values.
(2) ID set value is the same between heating and cooling sides.
Individual setting cannot be accepted.
(7) Heater break alarm (option)
• Use the current transformer (CT) specified by Fuji.
• Heater break is detected only when single-phase heater
is used.
• Heater break alarm is not available when controlling the
heater by thyristor phase-angle control method.
• [alarm detection point] and [Heater current] are registered
using of front key.
