This instrument cor responds to a panel thicknes s of 1 to 10 mm.

• Install the noise filter on the panel which is always grounded and minimize the wiring distance between the noise filter output side and the instrument power terminals.

NOTES

(1) For thermocouple input, use the specified compensation wire. (2) For RTD input, use leads with low resistance and having no

resistance differences among the 3 leads.

(3) Conduct input signal wiring away from instrument power,

electric equipment power and load lines to avoid noise induction.

(4) Conduct instrument power wiring so as not to be influenced by

noise from the electric equipment power. If the instrument may be affected by external noise, a noise filter should be used.

• Shorten the distance between twisted power supply wire pitches. The shorter the distance between the pitches, the more effective for noise reduction.

•

Do not install fuses and/or switches on the filter output signal since this may lessen filter effect.

(5) For power supply wires, use twisted wires with low voltage

drop.

(6) About 5 to 6 sec are required as the preparation time for

contact output after power on. Use a delay relay when the output line, is used for an external interlock circuit.

(7) This instrument has no power supply switch nor fuses.

Therefore, install the fuse close to the instrument and the switch, if required.

• Fuse type ; Time-lag fuse

• Recommended fuse rating : Rated voltage ; 250 V

Rated current ; 1 A

(8) For the current input specification, a resistor of 250Ω (±0.02%

±10ppm, 0.25 W or more) must be connected between the input terminals. This resistor must be provided by the customer.

(9) Do not excessively tighten the terminal screws. In addition,

use the solderless terminal appropriate to the screw size. (Screw size: M3x6, recommended tightening torque:0.4N!m [4kgf!cm])

(10) To the instrument with power supply of 24V, please be sure to

supply the power from SELV circuit.

*1: Precautions for heater break alarm (HBA) setting

,#Displayed only for when HBA is selected as second alarm. ,#HBA is not available on a current output. ,#Set HBA set value to a value about 85 % of current transformer input value (CT). However, when power supply variations are

large, set the HBA to a slightly smaller value. In addition, when two or more heaters are connected in parallel, set the HBA to a slightly larger value so that it is activated even with only one heater is broken (However, within the value of CT).

,#When the HBA set value is set to "0.0" or the current transformer is not connected, the HBA is turned on.

*2: Precautions for control loop break alarm (LBA) setting

,#Displayed only for when LBA is selected as first alarm or second alarm. ,#Usually set the set value of the LBA to a value twice the integral time (I). ,#No control loop break alarm can be used at heat/cool PID control action. ,#No LBA function is activated while the AT function is activated. ,#The LBA function is activated only at the 0 % or 100 % of PID computed value. Therefore, the time from trouble occurrence till the

activation of the LBA function equals the time until the PID computed value becomes 0 % or 100 % plus the LBA setting time.

,#If LBA setting time is too short or does not match the controlled object, the LBA may be turned on and off or not be turned on. In

this case, depending on the situation, change the LBA setting time.

6. OPERATIONS

6.1 Operation procedures

(1) Prior to starting operation, check that the mounting and wiring

have been finished, and that the SV and various parameters have been set.

(2) As this instrument does not have a power supply switch, it is

ready to operate as soon as the power is turned on. Prior to factory shipment, the instrument is set to "RUN (operation start)."

•

If the instrument is switched to operation stop (STOP), its display, output, etc. become as follows.

•

Display : The PV display unit shows (STOP).

•

Output: Control output OFF, Alarm output OFF

•

Suspended when the AT function is activated. (The PID constants are not updated.)

•

Stopped when the ST function is activated. (Re-started in RUN mode.)

•

This instrument holds the conditions that exist just before the power is turned on. For example, if the power is turned off in STOP mode, the instrument starts in STOP mode when the power is turned on again.

6.2 Set data lock (LCK) function

The set data lock function is used to prevent misoperation by not setting any parameter which is not used frequently. The parameter thus locked cannot be set or changed, but can only be monitored.

6.3 Autotuning (AT) function

The AT function automatically measures, computes and sets the optimum PID and LBA constants. This function is activated afterON, during temperature rise and/or when control is stabilized from any process state.

!"!"

Requirements for AT start

Start AT when all the following conditions are satisfied:

•

Prior to starting the AT function, end all the parameter settings other than PID and LBA.

•

Confirm the LCK function has not been engaged.

!"!"

Requirements for AT suspension

The AT function is suspended if any of the following conditions is established:

•

When the SV is changed.

•

When the PV bias value is changed.

•

When the RUN/STOP function is changed to the "STOP."

•

When the PV becomes abnormal. (According to the burnout.)

•

When the power is turned on.

•

When a power failure longer than 20 ms occurs.

•

When the AT function does not end in about 9 hours after tuning started.

•

If the AT suspension condition is established, the AT function is immediately suspended to be changed to PID control. The PID and LBA constants at this time are the same as before starting AT. In addition, even if the AT is completed, it is automatically transferred to PID control.

•

If any problems arise due to hunting exists in the control system, do not use the AT function. In this case, set each value to match the controlled object.

6.4 Self-tuning (ST) function

The ST function is used to automatically calculate and set adaptive PID constants anytime when the power is turned on; the SV is changed or the control system becomes oscillatory as the characteristic of the controlled system varies.

••••

In a controlled system in which ripples may be contained by the application of periodic disturbances, use this instrument with the ST function turned off.

••••

When the power is turned on or the SV is changed with the ST function turned on, turn on the power of the controlled system (heater, etc.) before or just when the power of this instrument is turned on.

!"!"

Requirements for ST start

Start ST when all the following conditions is satisfied: The instrument should be in PID control. (P≠0, I≠0, D≠0 and ARW≠0.)

!"!"

Requirements for ST stop

The ST function is stopped if any of the following conditions is established:

•

When PV is out of the input range

(When the instrument is overscaled or downscaled)

•

When the ST function is set to the OFF state.

•

When the AT function is activated.

•

When the RUN/STOP function is changed to the "STOP."

•

When the power is turned off.

*1:

If the AT function is activated, the ST function is set to the stop

state. After the AT function is stopped, the ST function re-starts from the stop state.

*2:

If the operation state is changed from the "RUN" to "STOP," the

ST function is set to the stop state. If the operation state is changed from the "STOP" to "RUN," the ST function re-starts from the stop state.

•

When control action is in heat/cool PID action, the ST function is not activated.

•

The PID and ARW settings cannot be changed while the ST function is being activated. However, they can only be monitored.

NOTES

CAUTIONS

NOTES

CAUTIONS

Connect the input signal wiring, and then turn on the power. If the input signal wiring opens, the instrument judges the input is disconnected.

•

Upscale

: TC input , RTD input (Downscale when the input is shorted.)

•

Downscale

: TC input (To be specified when ordering), Voltage input (Current input)

*1 : Alarm output ON (However, for the W or A control action type, the control output on both heat-side and cool-side is

turned off.)

*2 : For 0 to 5 V DC or 0 to 20 mA DC, both control and alarm outputs are indefinite.

No influence is exerted upon the instrument for power failure of 20 ms or less. For power failure of more than 20 ms , the instrument performs the same operation as that at the time of power on after power recovery (This applies only when alarm action is turned off).

The alarm hold action is activated when not only the power is turned on, but also the SV is changed.
