   Failure to follow this instruction may result in explosion or fire.
3. Install on a device panel to use.
   Failure to follow this instruction may result in fire or electric shock.
4. Do not connect, repair, or inspect the unit while connected to a power source.
   Failure to follow this instruction may result in fire or electric shock.”)
5. Check ‘Connections’ before wiring.
   Failure to follow this instruction may result in fire.
6. Do not disassemble or modify the unit.
   Failure to follow this instruction may result in fire or electric shock.

Caution Failure to follow instructions may result in injury or product damage

1. When connecting the power input and relay output, use AWG 20 (0.50 mm2) cable or over, and tighten the terminal screw with a tightening torque of 0.74 to 0.90 N m.
2. When connecting the sensor input and communication cable without dedicated cable, use AWG 28 to 16 cable and tighten the terminal screw with a tightening torque of 0.74 to 0.90 N m.
   Failure to follow this instruction may result in fire or malfunction due to contact failure.
3. Use the unit within the rated specifications.
   Failure to follow this instruction may result in fire or product damage
4. Use a dry cloth to clean the unit, and do not use water or organic solvent.
   Failure to follow this instruction may result in fire or electric shock.
5. Keep the product away from metal chip, dust, and wire residue which flow into the unit.
   Failure to follow this instruction may result in fire or product damage.

Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
• Check the polarity of the terminals before wiring the temperature sensor. For RTD temperature sensor, wire it as 3-wire type, using cables in same thickness and length.
  For thermocouple (TC) temperature sensor, use the designated compensation wire for extending wire.
• Keep away from high voltage lines or power lines to prevent inductive noise. In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input signal line. Do not use near the equipment which generates strong magnetic force or high frequency noise.
• Do not apply excessive power when connecting or disconnecting the connectors of the product.
• Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
• Do not use the unit for other purpose (e.g. voltmeter, ammeter), but temperature controller.
• When changing the input sensor, turn off the power first before changing. After changing the input sensor, modify the value of the corresponding parameter.
• Do not overlapping communication line and power line. Use twisted pair wire for communication line and connect ferrite bead at each end of line to reduce the effect of external noise.
• Make a required space around the unit for radiation of heat. For accurate temperature measurement, warm up the unit over 20 min after turning on the power.
• Make sure that power supply voltage reaches to the rated voltage within 2 sec after supplying power.
• Do not wire to terminals which are not used.
• This unit may be used in the following environments.
  • Indoors (in the environment condition rated in ‘Specifications’)
  • Altitude Max. 2,000 m
  • Pollution degree 2
  • Installation category II

Crimp Terminal Specifications

Unit: mm, use the crimp terminal of the following shape.

Mode Setting

Parameter Reset

1. Press the [◄] + [▲] + [▼] keys for over 5 sec. in run mode, INIT turns ON.
2. Change the setting value as YES by pressing the [▲] , [▼] keys.
3. Press the [MODE] key to reset all parameter values as default and to return to run mode.

Parameter Setting

Some parameters are activated/deactivated depending on the model or setting of other parameters. Refer to the descriptions of each item.
[MODE] key: Move to next item after saving / Return to RUN mode after saving (≥ 3 sec) / Return to previous parameter after saving (within 1 sec returning to RUN mode)
[◄] key: Select parameter / Move digits / Return to the upper level without saving (≥ 2 sec) / Return to RUN mode without saving (≥ 3 sec) ][▲] , [▼] key: Select parameter / Change setting value

• Return to the upper level without saving when there is no key input for more than 30 seconds.
• The range in parentheses ‘( )’ is the setting range when the set value of the ‘input specification’ parameter is used with one decimal point.
• Recommended parameter setting sequence: Parameter 2 group → Parameter 1 group → SV setting mode

Disposal

This symbol must appear on any electrical and electronic equipment placed on the EU market. This symbol indicates that this device should not be disposed of as unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose of it separately from unsorted municipal waste. Spent batteries and accumulators, which are not enclosed by the WEEE, as well as lamps that can be removed from the WEEE in a non-destructive manner, must be removed by end users from the WEEE in a non-destructive manner before it is handed over to a collection point.

Distributors of electrical and electronic equipment are legally obliged to provide free take-back of waste. Conrad provides the following return options free of charge (more details on our website):

• in our Conrad offices
• at the Conrad collection points
• at the collection points of public waste management authorities or the collection points set up by manufacturers or distributors within the meaning of the ElektroG

End users are responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of WEEE may apply in countries outside of Germany.

Parameter 1 group

Parameter 2 group

1. Below parameters are initialized when the setting value is changed.
   1. Parameter 1 group: AL1 alarm temperature,
   2. Parameter 2 group: Input correction, SV high/low limit, LBA band, Alarm output Hysteresis
2. If SV is lower/higher than low/high limit when the value is changed, SV is changed to the low/high limit value.
3. When changing the value from PID to ONOF, each value of following parameter is changed. 2- 28 Digital input key: OFF, 2-29 Sensor error, MV: 0.0 (Setting value is lower than 100.0)
4. After auto tuning, the range is set as twice of the integral time automatically. If the previous setting value is outside of the range automatically set, it is set to the nearest Max. or Min. value of the range.
5. After auto tuning, the range is set as 10% of the proportion band automatically. If the previous setting value is outside of the range automatically set, it is set to the nearest Max. or Min value of the range.
