Proper Usage
Simple failure diagnosis
● LED indicators flash (for 0.5 sec. in turn), or external
device displays OPEN.
●●Check●input●sensor●setting.●
●●Disconnect●the●power●and●check●the●input●connection.●
●●If●input●is●connected,●disconnect●the●input●wiring●
from●the●temperature●controller●and●short●the●+●and●-●
terminals.●Power●the●temperature●controller●and●check●
if●the●external●device●displays●the●room●temperature.●If●
it●does●not●display●the●room●temperature●and●continues●
to●display●HHHH●or●LLLL,●the●controller●is●broken.●
Please●contact●our●technical●support.●(input●type●is●
thermocouple)
● Output does not operate normally.
●●Check●that●CH●indicators●for●control●output●operates●
normally.●
●●If●CH●indicators●for●control●output●does●not●operates,●
check●the●parameter●settings.
●●If●CH●indicators●●for●control●output●operates,●remove●
the●control●output●connector●and●check●the●output.●
● External device receives no-response or abnormal
data.
●
●●Check●the●communication●converter●(SCM-38I●or●
SCM-US,●sold●separately).●
●●Do●not●install●communication●converter●line●and●AC●
power●supply●lines.
●●Use●different●communication●converter●power●and●
temperature●controller●power.●
●●Indicates●damage●to●internal●chip●by●strong●noise.●●
Please●contact●our●technical●support.●Locate●the●
source●of●the●noise●device●countermeasures.●
● Communication does not work between TM and
external device
●●Check●the●communication●converter●power●and●
connections.●
●●Check●the●communication●settings.●
●●Check●the●temperature●controller●and●external●device●
connections.

Caution during use
● ● Use●DC●power●only.
● ● Must●use●DC●power.●
● ● After●connecting●input●sensors●and●supplying●the●power,●
use●the●controller●20●minutes●later.●
● ● If●measurement●accuracy●is●low,●check●the●Input●Bias●
parameter●setting.●
● ● Install●a●power●switch●or●circuit●breaker●to●control●the●
power●supply.
● ● The●power●switch●or●circuit●breaker●should●be●installed●
where●it●is●easily●accessible●by●the●user.
● ● The●unit●is●for●temperature●controller.●Do●not●use●the●unit●
as●volt-meter●or●ampere-meter.●
● ● When●line●extension●between●thermocouple●and●
temperature●controller●is●required,●use●the●specified●
compensation●line.●If●using●the●general●line,●temperature●
difference●at●the●joint●part●between●thermocouple●and●
extension●lines.●
● ● When●using●RTD●temperature●sensor,●must●wire●it●as●
3-wire●type.●If●cable●is●extended,●use●3●wires●which●are●
same●thickness●as●the●line.●It●might●cause●the●deviation●
of●temperature●when●line●resistance●is●different.
● ● Please●separate●the●unit●wiring●from●high●voltage●lines●or●
power●lines●to●prevent●inductive●noise.
● ● If●power●line●and●input●signal●line●are●close●each●other,●
install●line●filter●for●noise●protection●at●power●line●and●use●
shielded●input●signal●line.
● ● Keep●away●from●the●high●frequency●instruments●(High●
frequency●welding●machine●&●sewing●machine,●large●
capacity●SCR●controller)●or●the●devices●(radio,●television,●
wireless●machines)●which●●causes●high●frequency●
interference.
● ● Before●changing●the●input●sensor,●turn●OFF●the●power.●
Connect●the●input●sensor●and●re-supply●the●power,●
change●parameter●settings●via●communication.●
● ● If●changing●the●communication●address●by●setting●switch,●
use●the●flat●head●driver●which●is●2mm●size●or●plastic●
driver.●If●not,●it●may●cause●product●damage.●
● ● Use●twisted●pair●wire●for●RS485●communication.●Connect●
ferrite●bead●at●each●end●of●line●to●reduce●the●effect●of●
external●noise.●
● ● Do●not●overlapping●communication●line●and●AC●power●
line.●
● ● Install●the●unit●at●well●ventilation●place.●If●not,●take●the●
ventilation●countermeasures.
● ● This●unit●may●be●used●in●the●following●environments.
