• Locations in which the ambient temperature falls outside the range of –10 to 50 °C when equipment is in use.

• Locations with rapid temperature changes, leading to dew condensation

• Locations with corrosive gases (especially sulfi de gas, ammonia, etc.) or fl ammable gases.

• Locations with vibration or shock directly. (Vibration and shock may cause output relay malfunction.)

• Locations in contact with water, oil, chemicals, steam or hot water. (If the equipment gets wet, there is a risk of
electric shock or fi re, so have it inspected by Fuji distributor.)

• Locations with high concentrations of atmospheric dust, salt or iron particles.

• Locations with large inductive interference, resulting in static electricity, magnetic fi elds or noise

• Locations in direct sunlight.

• Locations that build up heat from radiant heat sources, etc.

●

Recommended site conditions

• A place where the ambient humidity during operaion is between 45 to 85% RH.

About EMC standard

●

This equipment is a class A , for industrial locations, equipment. Do not use this equipment in domestic
establishment, such as residential areas, or it may cause radio interference. If you use this equipment in
domestic locations, take adequate measures on the outside of the equipment to reduce radio interference.

●

Under the requirement of EMC standard, the maximum length of external cable including a sensor to be
connected to this equipment is 30 m. Do not connect the sensor longer than 30 m.

Panel mounting

●

Insert the controller unit into the panel cutout from the front, and then put the mounting bracket from the rear.
The mounting bracket should be pushed in until the controller is securely fi xed to the panel. If there is a slight
gap remaining, gently tighten the two screws until the gap disappears. (Make sure not to over tighten the screws,
as doing so may result in the mounting bracket separating from the stopper.)

●

The front of this equipment is waterproof in compliance with NEMA-4X standards (IP66- equivalent). To effect
waterproof, the included packing is shall be attached between the controller and the panel according to the
guidelines below. (Incorrect attachment may cause the equipment to lose its waterproof capabilities.)
(1) As shown in Fig. 1, insert to the panel after attaching the packing to the equipment case.
(2) As shown in Fig. 2, tighten the screws of the mouthing bracket so that no gaps can remain between the

equipment face, the packing and the panels. Once fi nished, confi rm that there are no changes in shape such

●

Do not block the air vents on the top and bottom of the case.

Wiring

●

For thermocouple input, use the designated compensation lead; for RTD input, use wires with small lead wire
resistance and without any resistance difference among the three wires.

●

To avoid noise conductor effects, input signal wires should be separated from electric power lines or load lines.

●

Input signal wire and output signal wire should be separated each other. And both should be shield wire.

●

If there is a lot of noise from the power source, adding an insulation transducer and using a noise fi lter is
recommended. Always attach a noise fi lter to a panel that is grounded securely, and keep the wiring between
the noise fi lter output side and the measuring equipment power terminal wiring to a minimum length. Please do
not attach fuses and switches, etc. to the noise fi lter output wiring; otherwise the fi lter’s effectiveness will be
decreased.

●

Twisting the power wires is effective when connecting the wires. (The shorter the pitch of the twist, the more
effective the connection is against noise.)

●

Operation preparation time is required for the contact output when power is turned on. If using it as a signal to an
external interlock circuit, please couple it with a delayed relay.
Concerning the output relay, connecting the maximum rated load will shorten the product’s life; so please attach
an auxiliary relay. If the output operation frequency is high, selecting a SSR drive output type is recommended.
[Proportionate cycles] Relay output: 30 seconds or more, SSR drive output:
1 second or more

●

When inductive loads such as magnetic opening/closing equipment, etc. as relay output equipment are connected,
use of a surge absorber is recommended in order to protect the contacts against opening/closing surges and to
ensure long-term use.

ON/OFF (2-position)
control

PID control

Fuzzy control

Self tuning control

PID2 control

You can set the temperature control function in the parameter [CtRL] (see page 36).

Switches output control ON/OFF according to the SV/PV magnitude relationship.
Control systems can be built from simple elements such as SSR. This is appropriate
for situations where high accuracy is not required.

PID calculation and controls proceed according to the previously set PID parameters.
PID parameters can be set manually or through auto-tuning ([AT]).
It is the most basic control in this equipment.

Reduces the amount of overshoot during control. It is effective when you want to
suppress overshoot while changing SV, even during processes where it may take a
long time to reach the target value.

Adds controls while automatically calculating PID to meet the control target or
changing SV. It is effective when the control conditions change frequently.

Suppresses the amount of overshoot during control for processes that turn the control
target off and then on again. It is effective when the control target turns on and off
while power fl ows continuously to the temperature controller.

power is turned off. If the power is turned off during auto tuning, the auto-tuning function is invalidated with PID
parameters unchanged. In such a case, start again from the beginning.

●

Since ON-OFF operation (2-position operation) is performed during auto tuning, PV may fl uctuate greatly
depending on the process. Do not perform auto tuning for the processes where large fl uctuation of PV is not
allowed. Do not perform auto tuning, either, for the processes where the response is quick, such as pressure
control or fl ow rate control.

●

If auto tuning does not end after 4 hours, it means that tuning may not be completed successfully. Check input/
output wiring and parameters such as control output (forward, reverse) and input sensor type.

●

Carry out the auto-tuning again when:

• you change SV,

• you change PV input type, or

• operation does not work properly due to the change in operating conditions.

●

You can run auto-tuning when the control type is set to “ FUZY ” or “ Pid2 .” (see page 36)

●

You cannot run auto-tuning during manual mode. (see page 20)

●

When you are using the PID selection function, the auto-tuning result for the selected PID group is stored.

●

Auto tuning is forcibly terminated when SV is changed by the ramp soak function, remote SV function, or ramp
SV.

Since ON/OFF control is performed during auto-tuning, overshoot against the SV
may occur. To reduce the overshoot, execute the auto-tuning with “ L-oN ” (Low PV).

The following control methods are available with PID settings.

ON/OFF control
(2-position control)

PID control

PI control

P control

When [P] = “ 0 ” or the control method [CtRL] is set to “ oNoF ,” ON/OFF control is
used. Use this function when you want to run simple control without worrying about the
controllability.

Use this function when you want to control with high controllability.
[P], [i], and [d] should be adjusted to optimal values for the control target, although Pid
can be activated by setting the control method [CtRL] to “ Pid ,” and [P] ≠ “ 0.0 ,” [i] ≠ “ 0 ,”
[d] ≠ “ 0.0 .”
In normal situations, run auto-tuning to optimally adjust P, I, and D before using this
function.

When the control method [CtRL] is set to “ Pid ” and [P]≠“ 0.0 ”, [i]≠“ 0 ”, [d]=“ 0.0 ,” D
control is turned off and PI control is used.

When the control method [CtRL] is set to “ Pid ” and [P]≠“ 0.0 ”, [i]=“ 0 ”, [d]=“ 0.0 ,”
I and D controls are turned off and P control is used. In principle, P control generates
offset and PV does not agree with SV. In this case, adjust the output convergence value
[bAL].

●

Running auto-tuning automatically sets the optimal PID. (see page 25)

●

The PID settings confi gured by auto-tuning are generally considered to be optimal settings. If you want to change
the responsiveness, adjust PID manually.

●

Generally, control becomes unstable when [P] is set too small. On the other hand, setting it too big makes the
response slow.

●

If you set [P] to “ 0.0 ,” the control method parameter [CtRL] automatically turn to “ oNoF. ”

●

Set the hysteresis for the ON/OFF (2-position) control with the parameter [HyS]. (see page 32)

Parameter functions and setting procedure

dSP1

to

dP14

Parameter mask (126 to 139)

[Description] –––––––––––––––––––––––––––––––––––––––––––––––––––––––

The parameter mask allows you to hide unused parameters or to skip over the parameters you want to keep their
setpoints.

Do not let the parameters which are not described in this operation manual appear
on the screen.

●

Each parameter has the mask DSP which is the combination of a code (dSP1 to dSP9, dP10 to dP14) and an
integer, connected with a hyphen. For example, the mask DSP for the integral time [i] is “dSP3-4”, which is a
combination of the code “dSP3” and an integer “4.”

• To hide one parameter:

Convert the integer of the mask DSP of the parameter you want to hide into a hexadecimal number.
For example, if you want to hide the integral time [i], of which mask DSP is dSP3-4, set the parameter [dSP3]
to “0004.”

• To hide multiple parameters of the same code:

Convert the total of the two integers into a hexadecimal number.
For example, if you want to hide the integral time [i] (dSP3-4) and the deviation time [d] (dSP3-8), the total of
two integers is “12.” Set the parameter [dSP3] to “000C,” which is the hexadecimal of 12.

dSP3 - 4
dSP3 - 8

The same code

Total integer:

“12”

Convert to
the hexadecimal number

“000C”

• To reshow a parameter that has been hidden:

Subtract the integer of the mask DSP of the parameter you want to reshow from the set value. Set the parameter
to the hexadecimal of the subtracted value.
For example, if you want to reshow the deviation time [d] (dSP3-8) when the [dSP3] is set to “000C” which is
the hexadecimal of “12,” change the setting of [dSP3] to “0004” which is the hexadecimal of “4.”

●
