symbol indicates caution due to special circumstances in which hazards may occur.

Warning Failure to follow instructions may result in serious injury or death

Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss.(e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.) Failure to follow this instruction may result in personal injury, economic loss or fire.

Do not use the unit in the place where flammable/explosive/corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact or salinity may be present. Failure to follow this instruction may result in explosion or fire.
Install on a device panel to use. Failure to follow this instruction may result in fire or electric shock.
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.

Check ‘Connections’ before wiring. Failure to follow this instruction may result in fire.
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

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. 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.
Use the unit within the rated specifications. Failure to follow this instruction may result in fire or product damage

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.
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 the same thickness and length. For the 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 equipment that generates strong magnetic force or high-frequency noise.
Install a power switch or circuit breaker in an easily accessible place for supplying or disconnecting the power.
Do not use the unit for another purpose (e.g. voltmeter, ammeter), but for temperature controller.

When changing the input sensor, turn off the power first before changing it. After changing the input sensor, modify the value of the corresponding parameter.
Make a required space around the unit for the 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 that 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

Press the [◄] + [▲] + [▼] keys for over 5 sec. in run mode, INIT turns ON.

Change the setting value as YES by pressing the [▲], [▼] keys.
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 description of each item.
The setting range in parentheses is for using the decimal point display in the input specification.
If there is no key input for more than 30 seconds in each parameter, it returns to RUN mode.

When pressing the [MODE] key within 1 second after returning to the operation mode from the parameter group, it will enter the parameter group before returning.
[MODE] key: Saves the current parameter setting value and moves to the next parameter.
[◄] key: Checks the fixed item / Moves the row when changing the set value
[▲], [▼] keys: Selects the parameter / Changes the set value
Recommended parameter setting sequence: Parameter 2 group → Parameter 1 group → SV setting

Disposal

This 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

The below parameters are initialized when the setting value is changed.
- Parameter 1 group: AL1/2 alarm temperature
- Parameter 2 group: Input correction, SV high/low limit, Alarm output hysteresis, LBA time, LBA band
- SV setting mode: SV
If SV is lower than low limit or higher than high limit when the value is changed, SV is changed to the low/high limit value. If 2-1 Input specification is changed, the value is changed to Min./Max. value of Input specification.
When the setting value is changed, the setting value of 2-20 Sensor error MV is initialized to 0.0 (OFF).

When changing the value from PID to ONOF, each value of the following parameter is changed. 2-19 Digital input key: OFF, 2-20 Sensor error MV: 0.0 (when setting value is lower than 100.0)
