Indicates a potentially hazardous situation which, if not avoided, may result in minor injury or property damage
• Since this product is not equipped with a power switch and fuse, install them separately on the outside.
(fuse rating: 250Va.c. 0.5Aa.c.)
• Please supply the rated power voltage, in order to prevent product breakdowns or malfunctions.
• To prevent electric shocks and malfunctions, do not supply the power until the wiring is completed.
• The product does not have an explosion-proof structure, so avoid using it in places with flammable or explosive gases.
• Never disassemble, modify, process, improve or repair this product, as it may cause abnormal operations, electric shocks or fires.
• Please disassemble the product after turning OFF the power. Failure to do so may result in electric shocks, product abnormal
operations or malfunctions.
• Please use this product after installing it to a panel, because there is a risk of electric shock.
• The contents of this manual may be changed without prior notification.
• Before using the product you purchased, make sure that it is exactly what you ordered.
• Make sure that there is no damage or abnormality of the product during the delivery.
• Please do not use it in case of the time setting is 0. It may be a cause of its malfunction.
• Please turn the power off before changing the time setting. In case of changing the time setting while it is ON, please reset it.
• Please use the product in places where corrosive gases (especially harmful gases, ammonia, etc.) and flammable gases are
not generated.
• Do not use this product at any place with direct vibration or impact.
• Do not use this product at any place with liquid, oil, medical substances, dust, salt or iron contents. (Use at Pollution level 1 or 2)
• Do not polish this product with substances such as alcohol or benzene. (Use neutral detergent.)
• Do not use this product at any place with a large inductive difficulty or occurring static electricity or magnetic noise.
• Do not use this product at any place with possible thermal accumulation due to direct sunlight or heat radiation.
• Install this product at place under 2,000m in altitude.
• When water enters, short circuit or fire may occur, so please inspect the product carefully.
• If there is excessive noise from the power supply, using insulating transformer and noise filter is recommended. The noise
filter must be attached to be a panel grounded, and the wire between the filter output side and power supply terminal
must be as short as possible.
• If putting the power cables closely together then it is effective against noise.
• Do not wire anything to unused terminals.
• After checking the polarity of terminal, connect wires at the correct position.
• When you install this product to a panel, please use switches or circuit breakers compliant with IEC60947-1 or IEC60947-3.
• Please install switches or circuit breakers at close distance for user convenience.
• Write down on a label that if the circuit breaker or switch is operating then the power will be disconnected since the circuit
breaker or switch is installed.
• For the continuous and safe use of this product, the periodical maintenance is recommended.
• Some parts of this product have limited life span, and others are changed by their usage.
• The warranty period for this product including parts is one year if this product is properly used.
• When the power is on, the preparation period of contact output is required. In case of using signals of external interlock
circuit or etc., use it with a delay relay.
• The input/output terminals are subject to electric shock risk.
Never let the input/output terminals come in contact with your body or conductive substances.

▍Function descriptions
※ Control method is determined by product code when ordered.
Proportional control is that an output capacity regarding a setting value (SV) is proportionally operated by a deviation. The
width which the output is varied within 0 ~ 100% is called proportional Band (PB). Therefore, for reverse action, if
PT=Present (Process) temperature.
PT < PB → Output capacity 100%
PT > PB → Output capacity 0%
PT = PB → Output capacity 50%
This is a control method that if PT is higher than SV then output will be OFF or if PT is less than SV, then the output will be ON.
Also, it is called 2-position control since it outputs either 0% or 100%. The status which the temperature is unstable and there is
high/low wave around SV is called hunting. The width between the point where its output is OFF because PT is higher than SV
and the point where its output is ON since PT is less than SV is called adjusting sensitivity, hysteresis. If the width, hysteresis, is
narrow, then high/low wave becomes smaller but the cycle of ON-OFF gets smaller so that it may severely damage to
electromagnetic switch, electrovalve or etc.. Especially, for controlling burner which is using freezer or electrovalve, 2-postion
control is generally used.
