Remote Display Unit (TFD Series, Sold Separately)
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 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.
● Compressor operation cycle when sensor break [CLE]
Set compressor operation cycle when sensor break.
Set as [0] and compressor output turns OFF when sensor break.
Setting range: 0 to 100 (min)
● Compressor duty ratio when sensor break [DUT]
Set compressor ON duty ratio when sensor break.
Setting range: 0 to 100 (%)

Operation cycle
(60 min)
E.g.) When compressor operation cycle when sensor break [CLE]
is set as 60 min and compressor duty ratio when sensor break
[DUT] is set as 50%, compressor output has 60 min cycle and
turns ON for 30 min and turns OFF for 30 min.
Functions
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.
※1: When starting compressor, if present value (PV) is out of hysteresis range, compressor output does
not turn ON and the compressor (COMP) output indicator is ashing during compressor start-up delay time.
※2: When compressor delay is completed and it is within compressor min. operation cycle, compressor output
does not turn ON and the compressor (COMP) output indicator is ashing. (The latest one has priority
between compressor restart delay time and compressor min. operation cycle.)
※3: When present value (PV) is out of hysteresis, compressor output does not turn ON and the
compressor (COMP) output indicator is ashing during compressor restart delay time.
※4: If present value (PV) is below the SV, compressor output maintains ON status during compressor
min. operation time. After compressor min. operation time, it turns OFF.
※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.
★For more information about parameters for compressor prevention, refer to user manual.
● Compressor start-up delay time [SDL]
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 [RDL]
To prevent frequent compressor ON/OFF, set compressor ON time after compressor turns OFF.
Setting range: 0 to 60 (min)
● Compressor min. operation time [ONT], compressor min. operation cycle [CYC]
To prevent frequent compressor ON/OFF, set min. operation time and min. operation cycle.
