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 con-
stants. Self-tuning control ensures stable control even during changes in
SP values or during disturbances. This is achieved by monitoring and learn-
ing 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 specifica-
tions (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 installa-
tion 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.

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 paral-
lel by non-insulated external switch inputs.
●Before connecting in parallel to other equipment, first check the conditions of the other equip-
ment.
●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.

8
●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.

■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 1 Set a negative value as the lower deviation limit (E1). If a positive value is set, a temperature
higher than the SP value will be used as the operating point.
Example: Enter “-10” to set an operating point of SP-10°C
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 ( Ct) 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.
