Remote display unit (TFD) displays current temperature or output
status of TF3 at remote place.
TFD cable is TFD-3: 3m, TFD-5: 5m.
Connect the phone-jack of remote display unit (TFD) to the data
loader port of TF3.
This unit is dedicated for TF3 Series and it does not directly
communicate with upper devices (PC, PLC, etc.)

If TFD communication with TF3 error occurs, TFD ashes display

component for 1 sec. Check the connection with TF3.

※

When connecting TFD to the data loader port of TF3, you cannot connect Autonics SCM-US (USB to Serial converter,
sold separately). for communication. Use SCM-US48I(USB to RS485 converter, sold separately), SCM-38I(RS232C to
RS485 converter, sold separately).

Compressor protection

This function is for preventing compressor from life cycle shortening or malfunction by overload and frequent ON/OFF
of compressor. As compressor protection settings, when compressor output does not ON, the front compressor (COMP)

output indicator (green) is ashing.

● Compressor start-up delay time [

If power turns ON instantly from break-down or power OFF, it delays start-up during the set time of compressor.
Setting range: 0 to 60 (min)

● Compressor restart delay time [

To prevent frequent compressor ON/OFF, set compressor ON time after compressor turns OFF.
Setting range: 0 to 60 (min)

● Compressor min. operation time [

To prevent frequent compressor ON/OFF, set min. operation time and min. operation cycle.
Setting range of compressor min. operation time: 0 to 60 (min),

If compressor output does not turn ON due to compressor output condition or parameter settings for compressor

protection, the compressor (COMP) output indicator is ashing.

Compressor control when sensor break

If normal temperature control is impossible due to sensor break, it controls compressor output by the set operation cycle
and duty ratio to protect control object. Until error is cleared, operation cycle and duty ratio are applied repeatedly. When
error is cleared, the compressor operates after completing the currently applied operation cycle and compressor restart
delay time.

Defrost control (except 1CH, compressor output model: TF31-1 )

When operating a compressor for a long time, an evaporator and a freezer are freezing and thermal e󰀩ciency of
compressor is decreased. For increasing thermal e󰀩ciency, defrost operation helps to remove frost or ice around of

evaporator.
Set defrost cycle, time, and end temperature, etc to operate defrost (heater/hot-gas defrost).

The front defrost (DEF) output indicator (green) turns ON during defrost output and it ashes during defrost delay operation.

In case of compressor+defrost or auxiliary (alarm/evaporator-fan) output model (TF3 -2 - ), defrost operation is
available when defrost/auxiliary output [

defrost.

Proper Usage

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 (CT) 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.

● 24VAC, 12-24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.

● 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.

● Install a surge absorber at each end of inductive load coil when controlling high-capacity power relay or inductive load (e.g.
magnet).

● 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.
