1. Installation Precautions
CautionThis instrument is intended to be used under the following environmental conditions (IEC61010-1):
Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 ) that does not change
rapidly, and no icing• An ambient non-condensing humidity of 35 to 85 %RH• No large capacity electromagnetic switches or cables through which large current is flowing.
• No water, oil or chemicals or the vapors of these substances can come into direct contact with the unit.
• Take note that the ambient temperature of this unit – not the ambient temperature of the control panel –must not exceed 50 (122 ) if mounted through the face of a control panel. Otherwise the life ofelectronic components (especially electrolytic capacitors) may be shortened.

2. Wiring Precautions
Caution• Do not leave wire remnants in the instrument, as they may cause a fire and/or malfunction.
• Use a solderless terminal with an insulation sleeve in which the M4 screw fits when wiring the instrument.
• Tighten the terminal screw using the specified torque (1.4 N•m). If excessive force is applied to the screw
when tightening, the terminal screw or case may be damaged.
• This instrument does not have a built-in power switch, circuit breaker and fuse. Therefore, it is necessary
to install a power switch, circuit breaker and fuse externally near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• Do not apply a commercial power source to the sensor which is connected to the input terminal nor allow
the power source to come into contact with the sensor.
• Use a thermocouple and compensating lead wire according to the sensor input specifications of thiscontroller.
• When using a relay contact output type, externally use a relay according to the capacity of the load toprotect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires.
• To prevent the unit from the harmful effects of unexpected high level noise, it is recommended that asurge absorber be installed between the coils of the external relay.
• For the Fan output, be sure to connect a fan to prevent excessive rise of oven internal temperature.
• Be sure to wire the Door Open Input to prevent malfunction. The Door Open/Closed switch is wired,
Timer counting stops while door is opened.

3. Operation and Maintenance Precautions
Caution• It is recommended that AT (auto-tuning) be performed during the trial run.
• Do not touch live terminals. This may cause electrical shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal and cleaning. Working on or
touching the terminal with the power switched ON may result in severe injury or death due to electricalshock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, be careful not to put pressure on, scratch or strike it with a hard
object.

11.1 PD Control Action
PD Control Action is a combination of P (proportional) Control Action and D (derivative) Control Action.
In P (proportional) Control Action, control is performed by the proportional period within the proportionalband in proportion to the deviation between the set temperature and measured temperature.
In D (derivative) Control Action, stable control is performed by minimizing the overshoot and oscillation
caused by rapid temperature change due to disturbance or when power is turned on.

ON/OFF Control Action
In ON/OFF Control Action, control output is turned ON when measured temperature is lower than the[Set temperature – Hysteresis]. If the measured temperature exceeds the set temperature, control output
is turned OFF.
In ON/OFF Control Action, overshoot, undershoot and hunting phenomenon are generated.
When the measured temperature largely exceeds the set temperature as shown below, this is called
overshoot. When the measured temperature largely drops below the set temperature as follows, this isreferred to as undershoot.
In hunting status, the result is an oscillating control status, as shown below.
