WARNING

CAUTION

Do not operate the keys with a propelling pencil or sharp-tipped object. Doing so might cause faulty operation.

In addition to the standard ON/OFF and PID controls, the SDC10 is also equipped with self-tuning control which does not require setting control constants. Self-tuning control ensures stable control even during changes in SP values or during disturbances. This is achieved by monitoring and learning the characteristics of the control target to automatically output control constants.

This function should be used according to the instructions given in the manual.

Use the SDC10 within the operating ranges recommended in the specifications (temperature, humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.). Failure to do so might cause fire or faulty operation.

Do not block ventilation holes. Doing so might cause fire or faulty operation.

Wire the SDC10 properly according to predetermined standards. Also wire the SDC10 using specified power leads according to recognized installation methods.

Failure to do so might cause electric shock, fire or faulty operation. Do not allow lead clippings, chips or water to enter the controller case. Doing so might cause fire or faulty operation. Firmly tighten the terminal screws at the torque listed in the specifications. Insufficient tightening of terminal screws might cause electric shock or fire. Do not use unused terminals on the SDC10 as relay terminals. Doing so might cause electric shock, fire or faulty operation. We recommend attaching the terminal cover (sold separately) after wiring

the SDC10. Failure to do so might cause electric shock, fire or faulty operation. Use the relays on the SDC10 within the service life listed in the specifica-

tions. Continued use of the relays after the recommended service life has expired

might cause fire or faulty operation. Use Yamatake Corporation's SurgeNon if there is the risk of power surges

caused by lightning. Failure to do so might cause fire or faulty operation.

Handling Precautions

●

Check the model number of the controller and terminal numbers on the label on the side of the controller to prevent any wiring errors.

●

Use crimped solderless wire connectors for M3.5 screws.

●

I/O signal lines should be routed at least 50cm away from power lines. Also, do not route I/O leads through the same distribution box or ducts.

●

Crimped solderless wire connectors must not contact other connectors.

●

Do not use unused terminals as relay terminals.

●

Two or more SDC10 series controllers can be connected in parallel by external switch input.

●

The controller can be connected with the Yamatake Corporation SDC20/30/40 series in parallel by non-insulated external switch inputs.

●

Before connecting in parallel to other equipment, first check the conditions of the other equipment.

●

Non-insulated external switch inputs are non-voltage contact inputs. So, use external switch for small current.

●

Pass a lead wire for carrying the heater current through a current transformer. Use the controller with the heater current within the specification range (allowable current).

Otherwise, the controller may be damaged.

●

The controller is designed not to function for six seconds after it is turned ON. This is to allow it to stabilize. The controller then enters the operation mode. However, warm up the controller to satisfy standard accuracy requirements. Warming up takes about 30 minutes.

●

Current transformer input cannot be used for 3-phase motors and phase control.

●

Devices and systems to be connected to this unit must have the basic insulation sufficient to withstand the maximum operating voltage levels of the power supply and input/output parts.

●

Use power supply with reinforced insulation for DC model.

CAUTION, risk of electric shock

CAUTION

■ Noise Countermeasures

●

Use power from a single-phase control power supply to reduce noise.

●

Install an insulating transformer when power line noise is excessive and use a line filter. (model number of Yamatake Corporation line filter: 81446364-001)

●

Use a CR filter to counteract fast-rising noise. (model number of Yamatake Corporation filter: 81446365-001)

Handling Precautions

●

When noise countermeasures have been taken, do not bundle primary and secondary cables together or route them through the same distribution box or ducts.

Note 2 Heater line break/overcurrent and control device short-circuit alarm.

Models with a current transformer input detect heater line breaks, overcurrent conditions and control device short-circuit alarms by input from the current transformer.

• Heater line break/overcurrent alarm (operation type: 7) Heater line break: This alarm is activated when the current at control output ON is

lower than the event setting (Ex Low). Set Ex High to “9999” to disable the overcurrent alarm.

Overcurrent: This alarm is activated when the current is higher than the event

setting (Ex High) when the control output is ON. Set Ex Low to “1999” to disable the heater line break alarm.

• Control device short-circuit alarm (operation type: 8) This alarm is activated when the current is higher than the event setting (Ex) when control output is OFF.

Note ● The current display ( C t ) in the operation mode indicates the current value when the

control output is ON. This displayed current value is not updated when control output is OFF and for 300ms after control output changes to ON.

Detection of the current value is not updated for 300ms after the current output state changes.

● The following shows an example of how to set the event setting during detection of a

line break.

Calculate the event setting using the heater current value at control output ON (monitor the displayed CT value) and heater current value at control output OFF (cannot be measured on the product) according to the following equation:

Event setting = {(heater current value at control output ON) + (heater current value at control output OFF)}/2

Direct/reverse setting (C14 and C15 2nd digit setting) The direct/reverse setting is used to reverse (invert an ON/OFF relationship) the operation of the event set

on the 1st digit. (0: Direct, 1: Reverse)

Handling Precautions

● Direct operation of the PV upper limit alarm and deviation upper limit alarm is the

same as the reverse limit of PV lower limit alarm and deviation lower limit alarm operation.

Example: Event operation type setting (1st digit): 3 (PV upper and lower limits)

Direct/reverse operation setting (2nd digit): 1 (reverse)

● When using the heater line break/overcurrent and control short-circuit alarm, set

the area to 3A or more.

Additional function settings (C14 and C15 3rd digit setting) Standby and latch operations can be added as additional functions to an event operation type set on the 1st

digit. Settings 0: No

1: Standby 2: Latch 3: Standby and Latch 4: Non 5: Standby at changing SP

Note ● Standby

The standby function prevents an event from turning ON, even when the ON condition of that event is satisfied at controller power ON or when the READY mode changes to the RUN mode.

Event output is activated when an ON condition is satisfied after an OFF condition has been satisfied. The standby state occurs at power ON when the PV value is the shaded area.

● Latch

Once event output is ON, the latch function holds an event in the ON state even when an OFF condition is satisfied. Follow the procedure below to reset the latch state.

Chapter 5 INITIAL SETTINGS

● When using the PV, deviation upper/lower limit and heater line break/overcurrent and

control device short-circuit alarm, set HYS so that the OFF point is not lost.

● How to Switch the SP Value

Up to four SP values can be switched by the following three methods:

By SP No.

By the

RDY

key

By external switch input

By SP No.

If the value of the 2nd digit of setup item C 1 3 is set to an odd-number (1, 3, 5, 7), pressing the

PARA

key in the operation mode displays the SP Nos. “S P - 0” through

to “S P - 3” on the upper display.

Pressing the , keys in this state changes the SP No. in the upper display, and switches the SP value.

The SP No. is not displayed if the value of the 2nd digit of setup item C 1 3 is set to an even-number (0, 2, 4, 6).

By the

RDY

key

If the value of setup item C 2 1 is set to “4”, the SP value can be switched by the

RDY

key. Holding down the

RDY

key for at least two seconds switches the SP No.

S P 0 → S P 1 → S P 2 → S P 3 → S P 0 and so forth.

By external switch input (optional function)

If the values of both setup items C 1 7 and C 1 8 are set to “1” (SP switching), the four SP values can be switched according to the ON/OFF states of the two external switch inputs.

Chapter 6 TUNING

6-1 Selecting the Control Method

The SDC10 is provided with three types of control method. Select the desired method according to the C t R l (control method) setup in parameter items.

0. ON/OFF control

1. Self-tuning : This control method automatically changes control constants when SP is changed, or disturbance occurs.

2. Control by PID fixed values : Control follows fixed PID values set by auto-tuning or manual operation.

6-2 Self-tuning

The controller can be self-tuned by setting the control method to self-tuning ( C t R l =

1). Tuning is automatically started and control constants are changed by the following op-

eration or when a change in state occurs in this state.

Start by SP change Start conditions:

• Initial start (*1) SP change of ±10%FS (*2) or more

• 2nd start onwards SP change of ±5%FS or more

*1 “Initial start” refers to initial tuning after the C t R l setting is set to 1. *2 “FS (full-scale)” refers to the width between the upper and lower temperatures set

by range code (setup item C04).

Example: ±10%FS when the range is -200 to +400°C becomes:

600 (°C) x 10 (%) = 60 (°C)

Start by generation of deviation Startup conditions:

• When the difference between SP and PV is sb or more

* sb: Self-tuning startup width. This is set in the parameter items.

Start by power ON or mode change from READY to RUN Start conditions:

• When the power is turned ON with the difference between SP and PV at ±sb or

more, or the mode is changed from READY to RUN

● Startup method

● Stop method

Change C t R l from 1 to 2. This fixes the PID values. PID values can also be changed by key entry.

6-3 Cautions During Self-tuning

Observe the following when using the self-tuning function:

• Turn heaters or other control devices ON before turning the controller ON.

• To turn a control device OFF, set the controller to the READY mode. When turning a

control device back ON again, set the controller to the RUN mode.

• When the power is turned OFF during self-tuning while the LED blinks, the control

constants used during tuning are not stored in controller memory.

If any of the above mistakes have been made, unsuitable control constants are stored to memory, which may result in unexpected control. If this happens, follow the procedure below to reset the controller.

Chapter 6 TUNING

• Use auto-tuning.

For details on how to use auto-tuning, see “6-4 Auto-tuning.”

• Reset the PID values, and resume self-tuning.

Set parameter item C t R l (control method) to “2”. Reset the PID values to the factory settings (P = 5.0, I = 120, d = 30). Set C t R l to “1”, and resume self-tuning.

Handling Precautions

● In the Case of Interference Control Targets

Control targets may be located to the left or right (above or below), and response may slow down as a result of mutual tuning being adversely affected by respective changes in temperature.

If this happens, either use control by fixed PID values (C t R l = 2), or set parameter item (S b) to “0”.

● In the Case of Control Targets Where Disturbance Is Generated Intermittently

Tuning results are sometimes adversely influenced when tuning control targets where intermittent temperature drops occur (e.g. during sealing on packaging machines).

If this happens, either use control by fixed PID values (C t R l = 2), or set parameter item (S b) to “0”.

6-4 Auto-tuning

Use the auto-tuning function in the following instances:

• To automatically calculate PID constants by control by fixed PID value (C t R l = 2)

• When startup is slow in self-tuning control

• When response startup is slow in self-tuning control The auto-tuning function can be used in either of self-tuning control (C t R l = 1) or

control by fixed PID values (C t R l = 2).

● Procedure

Hold the

PARA

key down for at least 3 seconds in the RUN mode and with the SP

value set to enter the parameter setup mode. Press the

PARA

key with C t R l set to “1” or “2”.

A t (auto-tuning) is displayed. Set “1”.

If “1” is already set, set to “0” then back to “1”.

Auto-tuning can also be stopped by using the external switch input function. To forcibly cancel auto-tuning midway, either set A t to “0”, or set the controller to the READY mode.

Phenomenon Remedy

Slow startup time Slow response PV value fluctuates Tuning does not end. PV value

fluctuates with a 2°C or more error between SP and PV value.

Tuning does not end. PV value is stable but PV does not end.

Large overshoot Control signals repeatedly turn

ON and OFF more than necessary.

Handling Precautions

● Auto-tuning does not function normally unless the control target is connected.

● The auto-tuning time from start to finish varies according to the control target.

● When auto-tuning is executed, control is suspended, and 0 to 100% output is

repeated several times. If this hinders operation, manually set the PID values.

● Sometimes suitable PID values cannot be obtained according to the control

target. If this happens, manually set the PID values.

The following describes auto-tuning operation:

Operation when the difference between SP and PV values is 10% FS or more and SP>PV

At startup, operation stabilizes at a temperature of about (SP - PV)/2

↓

The temperature rises again and reaches SP.

↓

Auto-tuning ends when stability is achieved.

Operation when the difference between SP and PV values is 10% FS or less and SP<PV

Cycling is repeated around the SP value.

↓

Auto-tuning ends when stability is achieved.

Chapter 6 TUNING

Execute auto-tuning. Set

C T R L to “2”, reset PID

Set the value of PV filter (parameter item) to “1.0” to “2.0”.

Operation ends though it takes a long time. The slower the response of the control target, the longer tuning takes.

Chapter 7 SPECIFICATIONS

(Note) The primary side and secondary side capacities are joined inside the controller. For

this reason, when performing the withstand voltage test for the panel and controller’s power supply, disconnect the wiring of grounded secondary side terminals and PV input terminals from those terminals. In some cases, the grounding / non-grounding type thermocouples and resistance bulb sensors are not guaranteed for the withstand voltage between the protecting tube and the inner sensor. Because of this, there will be a possible cause of failure if such a withstand voltage test is performed as it is.

● I/O isolation The following table shows mutual isolation between I/O items. Items surrounded by

solid lines are insulated from other signals. Items in dashed lines are not insulated:

Power supply Digital circuit PV input

External switch input 1
