CAUTION
HANDLING PRECAUTIONS
• Before wiring the SDC30/31, check the controller catalog No. and terminal Nos.
on the label on the rear of the body. After wiring the SDC30/31, be sure to check the wiring for any mistakes.
• Maintain a distance of at least 50 cm between I/O leads or communications leads and power leads of 100V or more. Also, do not pass these leads through the same piping or wiring duct.
Be sure to provide a switch within operator reach for shutting OFF the mains power supply of this controller in the main supply wiring.
Also, In case of AC power supply models, the main supply wiring also requires a slowoperating type (T) fuse (rated current: 0.5 A, rated voltage: 250 V). (IEC127)

Chapter 3 WIRING
Connect thermocouple wires to the terminals in case of a thermocouple input.
When a thermocouple is connected to terminals, or wiring is extended, connect the wires via a shielded compensating lead wire.
• For input/output other than thermocouples, use a shielded polyethylene insulated vinyl shielded cable for instrumentation use conforming to JCS-364 or equivalent (generally called twisted shielded cable for instrumentation use).
• A shielded multiconductor microphone cord (MVVS) may be used, if electromagnetic induction noise are comparatively low.

HANDLING PRECAUTIONS
• When the auxiliary output of this controller is input into an A/D converter or an analog scanner, variances in read-out data occurs, according to the device which is used in combination, causing inconvenience.
• Especially in the case of combination with a successive approximation type high speed A/D converter.
Therefore, combination with a low speed integration type A/D converter is highly recommended. Be sure to confirm the operation in advance by carrying out a combination test before actual use. Should variation trouble occur,the following countermeasures will be effective:
(1) Provide an isolator having no switching power supply between this controller and the device to be used in combination
(2) Provide a film capacitor of 0.01uF to 0.1uF between the input terminal of the device to be used in combination and the earth (Use a capacitor of rated voltage 250V min.).
(3) Make an averaging process by a personal computer at data read-out.

Chapter 4 SETTING THE SETUP ITEMS
This chapter provides descriptions on the setup items required for the instrument built in an equipment for the first time to be put in operating states.
HANDLING PRECAUTIONS
• It is necessary to set the operating conditions such as the input range and control action according to how to use the equipment, before operating the instrument. This is called a setup.
If the instrument has already been built in and its setup has been completed, this chapter may be skipped.
• When using a 2G model, adjust the motor position (setup item C36).
2G models do not operate normally in their shipped state.
• When the motor hunts on a 2G model, carry out the following:
- Re-adjust the motor position. (External causes sometimes prevent the correct adjustment value from being obtained.)
- Increase the dead zone (setup item C34). (The standard value is 10.0%. If the dead zone is set to a smaller value, revert the value to 10.0%.)
- Re-adjust PID. (If the adjustment is out, output will change unnecessarily, causing the motor to hunt.)
Before starting the setup, check the items and set values, which are necessary for the equipment to be used, in accordance with the setup items table.
Determine the setup values in advance, using the “Setting Work Sheets" at the end of this manual as an appendix.
• To execute the setup, place this instrument in the basic indication states.
The basic indication states means such that the No.1 indicator shows a PV, and No.2
indicator shows an SR, OUT or a heater current value.
If the instrument is not in the basic indication states, press the DISP key.
• There are 51 setup items from C01 to C51 (including missing numbers).
Among these items, set the necessary items only. Some items may use the initial values as they are.
• If there is no relevant item due to a special model, this Item No. is not indicated, but skipped.
Setup item C51 is used for factory adjustment.
After C51, C01 follows.

This setup item selects the control method of modular motor control on 2G (positionproportional) models.
0: MFB control (conventional) + inferred position control
Both the input MFB (Motor Feed Back) value and the internal inferred MFB value are used to achieve smooth motor position control even if the input MFB value is not smooth.
The internal inferred MFB value is sometimes used frequently according to the feedback resistance of the motor that is being used. This is because more accurate position control is being carried out. When the AL07 (T line break) alarm occurs, control automatically shifts over to inferred position control.
1: MFB control (conventional)
The motor is controlled according to the MFB value in the same way as in convention control methods. When the AL07 (T line break) alarm occurs, control automatically shifts over to inferred position control.
2: Inferred position control (MFB OFF)
The motor position is controlled without MFB control.
Check items
• When inferred position control is set, the closed relay turns on at all times when MV is set to 0.0%, and the open relay turns on at all times when MV is set to 100.0%.
• Whichever control method is selected, the modular control motor must be connected and automatically adjusted by C36. However, when “2: inferred position control” is selected, automatic adjustment is no longer required if the time from fully closed to fully open is accurately measured in second units and set to C39.
• By “2: inferred position control,” a deviation sometimes occurs between the MV value and the motor valve opening over prolonged use. This poses no problem in terms of control.

• Adjustments are not possible in the MANUAL mode.
DISP
• When the key is pressed during adjustment, adjustment is canceled, and the
DISP display returns to the basic indication status. Input by any key other than is not accepted.
• When using a new motor, be sure to carry out this adjustment with the motor actually in use. When adjustment is carried out in a state that differs from the actual state (e.g.
the valve is not fitted), an error may occur in the inferred position due to a different in the load placed on the motor.
• Hunting may occur during a single adjustment operation as a result of the motor characteristics or instrumentation state.
In this instance, carry out the adjustment again.
These setup items set the fully closed and fully open adjusted values when you want to use the valve opening position at the fully closed and open positions of the modular control motor at narrower settings than the current positions.
The following example shows how the new fully closed and open positions are set to a position 30 to 70% of the original fully closed and open positions after automatic adjustment by setup item C36.

Determine P=Proportional band, I=Integral time and D-Derivative time.
When setting I to 0, the integral action turns off so that the manual reset can be set.
When setting P to 0.0, the on-off action is selected, and the differential can be set.
However, P=0 cannot be set on model 5G (current output) and 2G (position-proportional).
Check items
• When setting P to other than 0.0, the differential cannot be set.
• When setting I to other than 0, the manual reset cannot be set.
These parameters oH and oL determine the upper and lower limits of the manipulated variable.
They also serve as the upper and lower limits of the integral limiter.
When no feedback (C35=2) is selected in the set up item C35 (modular motor control selection) on a 2G model, the manipulated variable becomes 0 to 100% regardless of this setting.
Check items
The setting ranges of oL and oH are 0 to oH and oL to 100, respectively.
Chapter 5 SETTING OF PARAMETERS
This is used for manually obtaining a control deviation when the integral is turned off.
This can be done when I=0 and P
≠
0.0.
This parameters can set a difference between the on point and the off point (differential, dead band) in on-off action.
When P=0.0, the on-off action is then ready to set the differential.
However, P=0 cannot be set on model 5G (current output) and 2G (position-proportional).

When use of the external disturbance inhibit PID constants is selected in the setup item
C19, up to eight groups of external disturbance inhibit PID constants (proportional band, integral time, derivative time) are indicated matched to the set value of setup item C08
(SP setting system) in addition to the regular PID constant group. These eight groups can be selected. Controller models on which RSP has been added are provided with external disturbance inhibit PID groups specifically for RSP.
For details, see PID constant (page 5-9).
Check items

External disturbance inhibit PID constants are set automatically by auto-tuning.
If both or one of the proportional band for external disturbance inhibit or regular proportional band is 0, the external disturbance inhibit function will not operate, and on-off action is selected.
3
If both or one of the integral time for external disturbance inhibit or regular integral time is 0, the external disturbance inhibit function will not operate, and control will use the manual reset preset to the regular PID group.
These parameters can set a difference between the event on and off points (hysteresis dead band).
To set an event on when the event is continuous when conditions for turning the event on are set to the event ON delay time, set the desired values to these parameters.

The event relay turns on if the PV value does not rise above the differential set value
(does not fall below the differential set value in the case of direct action) even after the on delay time when a manipulated variable greater than the event set value is being output by the control loop diagnosis event.

The PV value is indicated and controlled using the PV value obtained by adding the PV bias set value to the regular PV value.
Judgment of over-range (AL01) and under-range (AL02) is carried out on the PV value to which bias is added.
The RSP value is indicated and controlled using the value obtained by adding the RSP bias set value to the regular remote setting input (RSP) value.
Judgment of over-range (AL05) and under-range (AL06) is carried out on the RSP value before bias is added.
In the case of time-proportional output, the ratio between on and off is determined by control calculation taking a certain period of time as the basic time unit. The time that forms the “basic time unit” is the cycle time.

Chapter 6 OPERATION
This instrument is set not to function for up to seven seconds after the power is turned ON to allow it to stabilize. Though operation is possible after this seven seconds, allow at least one hour for the instrument to warm up so as to satisfy the specified accuracy.
When the power is turned ON, the No.1 indicator indicates the PV value, and the No.2
indicator indicates the SP value (MV value in the MANUAL mode). This is called the
“basic indication status.” In this basic indication status, the SP value, MV value (only during position-proportional output) and motor valve opening can be displayed on the
No.2 indicator by key operation.
Key operation also changes the status to the setting change status so that the SP value, event set value and assigned parameter set values can be changed.
Key operation also changes the status to the mode change status so that the AUTO/
MANUAL, RUN/READY, LSP/RSP and auto-tuning stop/start mode can be changed.
• In the RUN mode, setup items can be confirmed but their set values cannot be changed.

Chapter 6 OPERATION
HANDLING PRECAUTIONS
• Auto tuning does not function normally if it is not connected to a controlled system.
• Optimum PID values cannot always be obtained in certain controlled systems.
In such a case, set the PID values manually.
• During auto tuning operation, hunting may occur in the controlled system. If hunting is not desirable, set PID values manually.
• The time required for tuning depends upon the control system.
• With multi SP, the values obtained by auto tuning are written to the PID group corresponding to the present set SP.
• Auto-tuning is canceled when a PV burnout (alarm code 01, 02), change from the RUN to the READY mode, change from the AUTO to the MANUAL mode, or a power interruption occurs during auto-tuning.
• The SP group cannot be changed during auto-tuning. However, the SP value can be changed.
• When the SP group has been changed by external switch input, the results of auto-tuning are written to the PID group linked with the SP group before the change, and the external switch input is switched to the specified SP group after auto-tuning ends.
• When auto-tuning is carried out when zone PID use is selected, the results will be written to the PID group of the zone to which the SP belongs after autotuning ends.
• When auto-tuning is executed during SP ramp, SP ramp continues to operate.
Chapter 6 OPERATION
Auto tuning is provided to automatically obtain optimum PID values (Proportional band) (Integral time) and (Derivative time) by measuring control systems.
This auto tuning can be operated during the steady-state operation as well as at start-up time.
For the PID values employed during the steady-state operation, it is recommended to obtain these values by operating the auto tuning at the same time (during steady-state operation).
Chapter 7 TROUBLESHOOTING
This instrument always executes PV input check, or self-diagnosis. If a problem is detected, the instruments indicates an alarm code on the No.1 indicator.

EV:
A differential value between control output on point and OFF point.
This prevents the control output from turning ON/OFF on a short cycle when a PV becomes equal to an SP.
This refers to the differential during event action, or more specifically to the difference between the value by which the event status changes from OFF to ON, and the value by which the event status changes from
ON to OFF.

The SDC30/31 is designed for general-purpose applications but specific safety precautions must be taken when using it in applications such as safety devices for worker protection, start/stop control devices for transportation and material handling machines, aeronautical/aerospace machines, and control devices for nuclear reactors. The manual stresses that the device should never be used in applications where human safety may be put at risk.
The manual highlights several safety precautions, including grounding the FG terminal with a maximum resistance of 100 Ω, turning the power OFF before wiring or removing/mounting the device, avoiding contact with electrically charged parts, and not disassembling the controller. It also emphasizes using the device within its recommended operating ranges and ensuring proper ventilation.
The SDC30/31 is powered by 100 to 240V ac (operating power voltage 85 to 264V ac) with a frequency of 50/60 Hz. It has a maximum power or current rating of 18 VA. The operating temperature range is 0 to 50°C and humidity is 10 to 90%RH. It is designed for Installation category II (IEC664-1, EN61010-1) and pollution degree 2.
What does Alarm Code AL06 on the SDC31 Digital Indicating Controller signify?
Alarm Code AL06 indicates an RSP under-range condition. This alarm occurs only in remote SP (Set Point) mode when the RSP input is less than -10% of the input range. Recommended action includes checking the RSP wiring and the RSP input value.
What does the error code AL07 mean and how can it be resolved?
The error code AL07 indicates a T line breakage or FB line input error, which occurs only when C35=0 or 1. To resolve this, check the FB wiring and the FB input value.
What do the No.1 and No.2 indicators display when the device is powered on?
When the power is turned ON, the No.1 indicator indicates the PV value, and the No.2 indicator indicates the SP value (MV value in the MANUAL mode). This is called the “basic indication status.” In this basic indication status, the SP value, MV value (onlyduring position-proportional output) and motor valve opening can be displayed on the No.2 indicator by key operation. Key operation also changes the status to the setting change status so that the SP value,event set value and assigned parameter set values can be changed.Key operation also changes the status to the mode change status so that the AUTO/MANUAL, RUN/READY, LSP/RSP and auto-tuning stop/start mode can be changed.
What does alarm code AL02 indicate?
Alarm code AL02 indicates that the Process Variable (PV) input is less than -10% of the range (an Under-range condition). If this alarm occurs, check the sensor, the wiring, and the PV range.
