CAUTION

Cautions on installation

Avoid the following places for installation:

● A place where the ambient temperature may reach beyond the range of from 0 to 50°C while in operation.

● A place with rapid temperature changes, leading to dew condensation

● A place where corrosive gases (sulfide gas and ammonia gas, in particular) or combustible gases are emitted.

● A place with vibration or shock directly. (Vibration and shock may cause output relay malfunction.)

● A place exposed to water, oil, chemicals, steam and/or vapor.

(If the equipment gets wet, there is a risk of electric shock or fire, so have it inspected by the distributor.)

● A place where the unit is exposed to dust, salt air, or air containing iron particles.

● A place where the unit is subject to interference with static electricity, magnetism, and noise.

● A place where the unit is exposed to direct sunlight.

● A place where the heat may be accumulated due to the radiation of heat.

Recommended site condition:

● A place where the ambient humidity during operation is between 45 to 85%RH.

Caution on installation on panel

● Attach the included Fixtures (2 pieces) onto the top and bottom of PXF5/9 , and tighten them with a screwdriver. The

clamp torque is approx. 0.15 N·m (1.5 kg·cm) The plastic fixture is designed such that over tightening will cause

left/right cracking to the central area of the Fixtures and hence reduce the torque. Cracking to the central area will not

cause any problems in terms of usability of the equipment as is.

(However, do exercise caution in not applying too much torque because the casing is made of plastic.)

● The front of this equipment is waterproof in compliance with NEMA-4X standards (IP66-equivalent). However,

regarding waterproofing between the equipment and the panel, use the included packing to ensure waterproofing and

attach it according to the guidelines below. (Incorrect attachment may cause the equipment to lose its waterproof

capabilities.)

(1)As shown in Fig. 1, insert the panel after attaching the packing to the equipment case.

(2)As shown in Fig. 2, tighten the fixture screws so that no gaps can remain between the equipment face, the packing

and the panels. Once finished, confirm that there are no changes in shape such as displaced or improperly-fitted

packing, etc. as shown in Fig. 3.

● Please exercise caution if the panel strength is weak and gaps develop between the packing and the panel, as this will

result in the loss of its waterproofing capabilities.

5

PXF4

● In order not to hamper heat radiation, do not block the sides of the equipment.

● Do not block the air vents on the upper part of the terminal.

● For PXF9, please attach the Fixtures to the attachment holes in the center of the main unit.

Mounting on vertical plane (in horizontal position)

PXF5/9

Mounting on vertical plane (in horizontal position)

Cautions on wiring

● For thermocouple input, use the designated compensation lead; for resistance temperature sensors, use wires with small

lead wire resistance and without any resistance difference among the three wires.

● To avoid noise conductor effects, do not use input signal wires in close proximity with electric power lines or load lines.

● Use the input signal lines and output signal lines that are separated from each other and are shielded.

● If there is a lot of noise from the power source, adding an insulation transducer and using a noise filter is recommended.

Always attach a noise filter to a panel that is grounded securely, and keep the wiring between the noise filter output side

and the measuring equipment power terminal wiring to a minimum length. Please do not attach fuses and switches, etc.

to the noise filter output wiring since doing so will decrease the filter’s effectiveness.

● Twisting the measuring instrument wiring is effective when connecting the wires. (The shorter the pitch of the twist, the

more effective the connection is against noise.)

● When the power is turned on, it takes some time before a contact output starts operation. 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 relay’s life; so please attach an

auxiliary relay. If the output operation frequency is high, selecting a SSR drive output type is recommended.

[Proportional 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 serge absorber is recommended in order to protect the connection points against opening/closing surges and to ensure
long-term use.

Recommended specification for surge absorber

Key Operation Cautions/Error Operations

● The alarm function does not work properly when an error takes place unless the settings are made correctly. Always

verify its setting before operation.

● If the input wiring breaks, the display will read "UUUU" or "LLLL". When replacing the sensor, always turn the power

OFF.

Others

● Do not wipe the equipment with organic solvents such as alcohol or benzene, etc. If wiping is necessary, use a neutral

cleaning agent.

● Do not use mobile phones near the instrument (within 50 cm). Otherwise malfunction may occur.

● Trouble may occur if the equipment is used near a radio, TV, or wireless device.

● Do not turn off the power right after you change the setting. If you turn off the power after setting change, be sure to wait

for a few seconds before turning it off, so that the changed values can be stored on the nonvolatile memory.

• oFF (stop): Ramp/soak is stopped.

• RUN (start): Ramp/soak starts.

• HLd (hold): Ramp/soak hold. To release the hold, select "RUN" again.
The parameter information changes automatically depending on the ramp/soak state.

• GS (Guaranty soak ON): Guaranty soak is activated and PV is out of guaranty soak setting range.

• ENd (end): Ramp/soak has finished.
During ramp soak operation, one of RUN, HOLD, or END indicators light according to the state of ramp soak.
During ramp soak operation, on-going step No. and "r" (ramp) or "-" (soak) are displayed on the screen No. area
of operation screen (PV/SV screen).
For example, "2r" appears during step 2 ramp, and "2-" during step 2 soak.

AT Auto tuning (005)

[Description] ________________________________________________________________

Running auto-tuning automatically sets the optimal PID.

• Setting range

There are the following two types in auto-tuning.

• When auto tuning is normally completed, the automatically set PID parameter value is maintained even if the
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 fluctuate greatly
depending on the process. Do not perform auto tuning for the processes where large fluctuation of PV is not
allowed. Do not perform auto tuning, either, for the processes where the response is quick, such as pressure
control or flow 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.

• When you change SV or PV input type, or when operation does not work properly due to the change in
operating conditions, perform auto tuning again.

• You can run auto-tuning when the control type is set to "fuzzy" or "PID2".

• You cannot run auto-tuning during manual mode.

• 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.

Note:
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).

ON/OFF control
(2-position control)

When the control method CtRL is set to oNoF, ON/OFF control is used. Use the
this function when you want to run simple control without worrying about the
controllability.

PID control

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 with P ≠ 0, I ≠ 0, and D ≠ 0. In normal situations, run auto-tuning
to optimally adjust P, I, and D before using this function.

PI control

When P ≠ 0, I ≠ 0, and D = 0, D control is turned off and PI control is used.

P control

When P ≠ 0 and I = 0, D = 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”.

CH1 PID (Control parameters)

P Proportional band (050)
ｉ Integration time (051)

[Description] ________________________________________________________________

Allows you to set PID (Proportional Band, Integration Time, Differential Time).
Setting range

The following control methods are available with PID settings.

Running auto-tuning automatically sets the optimal PID. See "AT Auto tuning (005) " (page 33)
The PID settings configured 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.
Set the hysteresis for the ON/OFF (2-position) control with the parameter “hyS”.

Note
Do not perform auto tuning during ON/OFF control.

[Description] ________________________________________________________________

Allows you to set the hysteresis for ON/OFF (2 position) control

The controllability varies with the size of the hysteresis.

The relationship between SV and hysteresis in normal and reverse operation is shown below.

• During ON/OFF control, the i and d settings do not affect control.

• If the hysteresis width is narrow, and PV and SV are nearly equal, the output may frequently switch on and
off. Note that it may affect the life of the contact.

Cooling proportional band = (Proportional band P/2) x Coefficient

CooL Cooling proportional band coefficient (054)

[Description] _______________________________________________________________

Allows you to set the proportional band coefficient for cooling.

• Setting range: 0.0 to 100.0
The relationship between heating control output and cooling control output is outlined below.

Cooling proportional band is set after the optimal value for heating proportional band is set.

The following example shows how the cooling proportional band is calculated.
Example: Calculating the coefficient that will give a cooling proportional band of 10% when proportional
band(P) = 50% with full scale cooling
10% = (50%/2) x Coefficient
Coefficient = 0.4
To set cooling as a secondary operation, set "Cool" to 0.0.
With two outputs set as P=0.0 and Cool=0.0, heating and cooling outputs become ON/OFF actions (3-position
control). In this situation, the ON/OFF hysteresis is 0.5% FS (fixed) for heating and cooling outputs. The point
of operation for the heating output can be shifted with the “HYS” parameter. The point of operation for the
cooling output can be shifted with the “db” parameter.
The relationship between SV and hysteresis in normal and reverse operation is shown below.

db Dead band (055)

[Description] _______________________________________________________________

Shifts the cooling proportional band against the set value as follows.

"db" is called dead band when the value is positive, and overlap band when the value is negative.

• Range: -50% to 50%
"db" is measured as a percentage of MV and can be converted to a percentage deviation by the following formula.
DB [%] = deviation × 100/P [%]
Example: Proportional Band (P) = 5.0%, with a desired dead band of 1% deviation from SV:
DB [%] = 1.0 ×100/5.0 = 20 [%]
Dead band = 20 (%)

Note: When the dead band is set, MV for the cooling output will be limited to -5.0%, and the output may reach

less than 105.0%.
At this time, the output upper limit is represented as the equation below
Output upper limit [%] = -2 × (DB-55)/CooL (does not exceed 105.0%)
Example: When the DB = 20[%] and the Cool = 2, the cooling output will be limited to 35.0%

[Description] ________________________________________________________________

These coefficients are used to suppress overshoot generated in PID control.
The 2-degrees-of-freedom PID system of this instrument adopts set value (SV) filter method, which is effective
in suppressing overshoot at the time of setting change or start-up.
If ALPA (α) is set to 100.0%, and bEtA (β) to 0.0%, ordinary PID control (1 degree of freedom PID) is
performed.
Adjust ALPA (α) and bEtA (β) as follows.
(1)Set ALPA (α) to 40.0%, and bEtA (β) to 100.0%. (Factory default setting)
(2)Perform control and check responsiveness (overshoot volume).
If overshoot cannot be improved in this stage, adjust ALPA (α) and bEtA (β), following the definition listed

in the following table.
Generally, ALPA (α) does not require adjustment. Therefore, it is recommended to use the instrument with
ALPA (α) set to 40.0%.

Setting range

[2 degrees of freedom PID block diagram]

Note:
Changing ALPA (α) should be performed during manual mode.
Before changing ALPA (α) setting, set bEtA (β) to 0.0%. First, change ALPA (α) setting, and then set
bEtA (β) to desired value. Improper procedure may cause output (target value) to increase temporarily,
thus posing danger.
The purpose of this function is to suppress overshoot generated in ordinary PID control. Overshoot
may not always be eliminated.

PID palette parameters are used to register SVs, PIDs, and other control parameters. Up to seven sets of SVs and
PIDs can be stored, and you can toggle among them by simply selecting their numbers.
This is very useful when operating conditions change frequently.
The palette menu (CH2) consists of the following function blocks:
