2. Caution

(Example)

2-1. Cautions when Installing

Please avoid installing in the following locations.

● Locations in which the ambient temperature falls outside the range of –10 to 50°C when equipment is in use. (If the power supply is 200V AC, the recommended maximum ambient temperature is 45°C.)

● Locations with rapid temperature changes, leading to dew condensation

● Locations with corrosive gases (especially sulde gas, ammonia, etc.) or 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 fire, 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 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.

2-2. Cautions when Attaching to the Panels

● 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 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 xture screws so that no gaps can remain between the equipment

face, the packing and the panels. Once nished, conrm that there are no changes in shape such as displaced or improperly-tted packing, etc. as shown in Fig. 3.

● If the panel does not have enough strength, gaps may develop between the packing and the panel to lose waterproong capabilities.

2-3. Cautions for Wiring

● For thermocouple input, use the designated compensation lead; for resistance bulb 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 lter is recommended.

(Example: ZMB22R5-11, noise lter, Manufacturer: TDK) Always attach a noise lter to a panel that is grounded securely, and keep the wiring between the

noise 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 lter output wiring; otherwise the 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/SSC drive output type is recommended.

[Proportionate cycles] Relay output: 30 seconds or more, SSR/SSC drive output: 1 second or more

● If you selected the version with CT, use a common power line for the heater and the controller.

● 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.

2-4. 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". When replacing the sensor, always turn the power OFF.

2-5. Others

● Please 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 this equipment (within 50 cm). Otherwise a malfunction may result.

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

● This equipment should be treated as an industrial waste when it is disposed of.

PID controls run as long as the parameter is set to " " = (" "). The PID controls calculate PID based on the set values for parameters " result (-5% to 105%). Each parameter can be set either by manually tuning the values or by running auto-tuning (AT) to automatically set the values.

key to set the value.

For more details on auto-tuning, see "7-7 Auto-tuning" (page 15)

7-4. Self-tuning Control

Self-tuning Control is a control which automatically calculates the value of PID, under the condition that the control target or set value (SV) changes. Self-tuning is especially effective for situations when a high level of control is not needed, but autotuning cannot be run due to frequent changes in the control target conditions.

Point

When a high level of control is required, choose PID control, fuzzy PID control, or PID2 control.

Conditions where self-tuning can be used

Self-tuning is used in the following situations:

● When temperature rises when the power is turned on

● When temperature rises when SV changes (or when the controller decides it is necessary)

● When the controller decides it is necessary because the controls have become unstable

Conditions where self-tuning cannot be used

Self-tuning cannot be used in the following situations:

● During control standby

● During auto-tuning

● During ramp soak progress

● When there is error input

● When set for dual output

● When any of the P, I, D, Ar parameters are set to manual

● During manual mode

● During soft start progress

Conditions to halt self-tuning

Halt self-tuning in the following situations:

● When there is a change in SV (This includes the case where SV changes because of the ramp soak function, remote SV function, or ramp SV.)

● When self-tuning has not nished after running for nine or more hours

In the case which the power supply of the control target goes ON → OFF → ON, this PID2 control can suppress the amount of overshoot. This control introduces an algorithm to prevent the calculated PID result from becoming a miscalculation, even when the control loop is open. You will need to run auto-tuning to set the PID parameter when using PID2 control.

7-6. 2-Degrees-of-Freedom PID Control

Suppresses the amount of overshoot during PID control. It uses the SV lter which is effective in reducing overshoot after a SV change or at startup. Controllability in 2-degrees-of-freedom PID control is different depending on the setting of the coefcient α and β. When the coefficient α = 100.0% and coefficient β =0.0% , the system performs the normal PID control. You can adjust the coefcient α and β as follows:

1) Set the coefcient α to 40.0% and β to 100.0%. (factory default setting)

2) Perform a control to check the response (small overshoot). If overshoot is not reduced by this measure, adjust the coefcient α and β in accordance with the following table. We recommend you to x the coefcient α to 40.0% because it usually requires no adjustment.

Control result Coefcient β coefcient α

Large overshoot Raise coefcient β by 20% Lower coefcient α by10%

Small overshoot Lower coefcient β by 20% Raise coefcient α by10%

● PID parameter which is set after auto tuning has finished normally will be maintained even when the power is turned off. However, the PID value will not be

changed if the power is turned off during auto- tuning. In this case, rerun auto-tuning.

● The equipment will use ON/OFF (2 position) control during auto- tuning, so there may be a large change in PV according to the process. Do not use auto-tuning for processes that do not permit a large change in PV. Do not use auto-tuning for processes such as pressure control and flow control that have a fast response.

● Auto-tuning is not behaving normally if it has not finished after four or more hours have

Point

passed. In these cases, recheck parameters such as input/output wiring, control output behavior (normal/ reverse), and input sensor type.

● Rerun auto-tuning if there is a large change in SV, a change in the PV input type, or a change in the control target conditions that reduces the effectiveness of the controls.

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

● You cannot run auto-tuning in manual mode.

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

● Auto tuning is forcibly terminated when SV changes because of the ramp soak function, remote SV function, or ramp SV.

1. Soft start function

When turning on the equipment (including the temperature controller), the soft start function suppresses the MV to become maximum output. It places an upper limit on MV output for a specied amount of time after power is turned on. This function is useful for effects such as suppressing the heater output during equipment startup, and makes load lightened. After the specied time has passed after switching on the equipment (or if SFTM = 0), the soft start function ends and normal controls begin.

4. Ramp SV function

The ramp SV function suppresses a sudden change in SV (step change) when changing SV.It allows SV to change smoothly according to the set slope of temperature per unit of time. This smooth SV change allows you to minimize the effect of the change on controls. You can set both inclining temperature and declining temperature slopes, and choose from "minutes" or "hours" for the time units. You can also choose for the SV display to show the current value or the target value during ramp SV.

9. Error Indications

8-1. Input Setting

Set the type and the range for input sensor. Input can be set in the setup menu (" "]. For more on input types, input scaling, decimal point location, and input codes, see "10 Input Range and Codes (standard range)". (page 19)

1. Choose an input type (" ")

Check the type of the thermocouple or resistance bulb which is used.

2. Set the PV scaling (input range) (" "/" ")

Set Pvb to the lower limit of the temperature range and PvF to the upper limit. It is recommended to set the values at the standard range, even though they can be set at values beyond of it. There is no standard range for DC voltage or DC current input. (-1999 to 9999, lower limit<upper limit)

3. Set the decimal point location (" ")

Sets whether or not to display digits after the decimal point. Two digits can also be displayed after the decimal point when using 1 to 5V DC, and 4 to 20mA DC.

Point

PV scaling and decimal point location can be used with the factory settings.

8-2. Output Setting

Sets the control output. (Only when the output is current or voltage.)

1. Sets the range of the control output (OUT1, OUT2) (" " ")"

Choose any of 0 to 5V, 1 to 5V, 0 to 10V, 2 to 10V, 0 to 20mA or 4 to 20mA DC.

8-3. Control Setting

Sets controls to normal operation or reverse operation.

● Reverse operation: As the process value (PV) rises, the control output (MV) becomes smaller. Used to heat the control object.

● Normal operation: As the process value (PV) rises, the control output (MV) becomes larger. Used to cool the control object.

1. Set the normal or reverse operation (" ") Choose any of the following combinations of heat and cool to suit your system.
