TCD/TCR Series digital display temperature controller

Pay attention to safety

※"Pay attention to Safety" is for the safe and correct use of the product to prevent the occurrence of dangerous accidents. Please observe the following contents.
※Attention safety can be divided into two parts: "warning" and "attention". The meaning is as follows:
⚠warning: if the violation of the tip, and may cause serious injury or death.
⚠note: such as violation of the tip, and may result in minor injury or product damage.

⚠warning

1. Double-protection safety devices must be installed when the machines (such as nuclear power control, medical devices, ships, vehicles, railways, aviation, inflammable devices, safety devices, disaster prevention/theft devices) have a significant impact on human life and property.Otherwise it may cause fire, personal injury or property damage.
2. The panel must be installed when using.
Otherwise there is a risk of electric shock.
3. Do not carry out maintenance work when the power is on.
Otherwise there is a risk of electric shock.
4. Please confirm the terminal number before connection.
It could cause a fire.
5. The product shall not be modified except the maintenance personnel of the company.
Otherwise it could lead to an electric shock or fire.

⚠note

1. Do not use this product outdoors.
    Otherwise, the service life of the product will be shortened or electric shock accident will occur.
2. When wiring the power input end and the relay output end, please use AWG 20 (0.50mm2) cable and keep the torque of the screw at 0.74N.m~0.90Nm.
    Bad contact may cause fire.
3. Please use the product within the rated specification.
    Otherwise, the life of the product will be shortened and there will be fire hazards.
4. Use loads less than the allowable capacity of relay contacts.
    Otherwise it will cause poor insulation, contact bonding, poor contact, relay damage, fire and so on.
5. Do not use water or organic solvent when cleaning, and wipe with dry towel.
    It could cause an electric shock or fire.
6. Avoid using the product in flammable, explosive, humid, direct sunlight, thermal radiation, vibration and other places.
    It could cause a fire or an explosion.
7. Do not allow dust or cable residue to enter the product.
    Otherwise it may cause fire or damage the product.
8. After confirming the polarity of the terminals, connect the thermocouple wiring correctly.
    Otherwise it could cause a fire or explosion.
9. For the purpose of enhanced insulation, please use a power supply that ensures above enhanced insulation.

Operation

Temperature setting and control

1. ON/OFF control: After the power supply is powered ON, set the required temperature setting value and start operation.When the actual temperature value is lower than the set value, the ON green light will be ON, and the normal opening point of the output relay will be ON, and the normal closing point will be off.When the actual value reaches or exceeds the set value, the OFF red light will be on and the normal opening point of the output relay will be disconnected and the normal closing point will be connected.
2. When the time ratio is controlled, after the power is powered on, set the required temperature setting value and start the operation.When the actual temperature does not enter the proportional band, the ON green light will be ON, and the normally open point of the output relay will be ON, and the normally closed point will be off.When entering the proportional band, the relay starts to switch regularly. The higher the temperature is, the shorter the output time is, and vice versa. The temperature is controlled by changing the average heating power of the load.
3, the use of the panel "RESET" potentiometer: when the time proportional control heating system balance, due to the load heating power of large or small, the actual value is lower than the set value of the static difference correction, adjust the potentiometer can eliminate the deviation, to adapt to different working conditions.

Fault message indication

Attention

1. In order to eliminate inductive interference, please wire the product separately with high-voltage lines, power lines, etc.
2.Use the M3 terminal in the following shape.

3. Please use the power switch or circuit breaker when turning off the power to the product.
4. Please install the switch and circuit breaker nearby for the operator to operate.
5. If the product is used as temperature indication or adjustment, it should not be used as other instruments.
6. When using the thermal resistance (RTD) sensor, 3 wires should be connected. If you want to extend the wire, you must use the same type and length of wire connection.If the impedance of the line is different, it may cause temperature deviation.
7. When the power line and the input signal line have to be installed closer, please add a filter at the power end and shield the signal line.
8. Keep away from high frequency equipment (high frequency welder, high frequency sewing machine, high capacity SCR controller)
9. When the measurement input is switched on, HHH or LLL will be displayed if any error occurs. At this time, check whether the input is wrong after power off.
10. This product is used in the following environments.
①indoor                                                                         ②pollution level 2 (pollution degree2)
③The Installation category ll is below 2000m.              ④Installation category ll
※If you violate the above precautions, it may cause product failure. Please be sure to comply.
