Proper usage
Simple failure diagnosis
● When display LED is flashing every 0.5 sec. or when
error message is indicated on external units
It●represents●input●sensor●open●error.●Cut●off●the●power●
of●controller●and●check●input●sensor●connection.
●●●If●sensor●is●properly●connected,●disconnect●sensor●
line●from●the●controller●and●short●the●input●terminal●(+)●
/●(-).●Then,●make●sure●that●current●indoor●temperature●
is●indicated.●If●current●indoor●temperature●is●properly●
indicated,●it●represents●no●errors●detected.●If●external●
unit●displays●'HHHH'●or●'LLLL',●please●contact●our●A/S●
center.●
●●(Current●indoor●temperature●checking●is●available●only●
if●selecting●thermocouple●type.)
Make●sure●proper●input●sensors●are●selected.
● When no output is operated
Check●output●display●LED●at●the●front.●In●case●output●
display●LED●does●not●work●properly,●please●check●
each●parameter●setting●again.●In●case●output●display●
LED●works●properly,●disconnect●the●output●terminal●
and●check●controller's●output●type●(Relay●contact,●SSR,●
Current)●again.
● When external units receive no response or error
data
●Check●communication●converter●first.●
●Do●not●install●the●unit●with●overlapping●communication●
converter●lines●and●AC●power●supply●lines.
●Use●separate●power●supply●(24VDC)●for●communication● ●
converter●if●possible.
Strong●external●noise●could●be●a●possible●cause●for●this●
symptom.●Please●contact●our●A/S●center.●In●addition,●
analyze●the●main●cause●that●triggers●strong●noise●
and●take●measures●to●prevent●it.●Even●though●this●
unit●complies●with●proper●noise●resistance●standards,●
consistent●noise●induction●could●affect●internal●circuit●
break.
● When communication does not work properly
Check●converter's●power●supply●and●connection.
Check●communication●setting.
Check●main●body's●connections●to●external●units.
Multi-Channel Module type PID Control
Caution for using
● ● Use●DC●power●only.
● ● Keep●the●ambient●temperature●-10℃●to●50℃.
● ● For●more●accurate●controlling,●start●temperature●
controlling●approx.●20●minutes●later●after●connecting●
input●sensors●and●supplying●power.●
● ● In●case●display●accuracy●does●not●meet●the●specification,●
check●Input●Bias●parameter●first.●
● ● Power●switch●or●a●circuit●breaker●must●be●installed●for●
proper●application.
● ● Make●sure●that●the●power●switch●or●a●circuit●breaker●
installed●near●operators.
● ● This●unit●is●solely●allowed●for●temperature●controlling●
application.●Do●not●apply●this●unit●as●a●voltage●meter●or●
current●meter.●
● ● When●line●extension●is●required,●please●use●specified●
compensation●line.●If●not,●there●occurs●temperature●
difference●at●the●joint●part●between●thermocouples●and●
extension●lines.●
● ● In●case●of●using●RTD,●line●connection●must●be●done●with●
3●wires.●When●line●extension●is●required,●use●the●same●
wire●with●material,●thickness●and●length.●Different●line●
resistance●may●cause●temperature●difference.●
● ● Make●sure●controller's●line●connection●must●be●separated●
from●high●voltage●line●or●power●supply●line●in●order●to●
prevent●induced●noise.●
● ● If●it●is●required●that●power●supply●line●should●be●
connected●near●input●signal●line,●use●line●filter●on●
controller's●power●supply●line●and●input●signal●line●must●
be●shielded.●
● ● Avoid●installing●controllers●adjacent●to●high●frequency●
noise●generating●units●including●high●frequency●soldering●
machine,●high●frequency●sewing●machine,●and●high●
capacity●SCR●controllers●and●motors.●
● ● Avoid●using●the●unit●near●radio,●TV●or●wireless●machines●
that●may●cause●high●frequency●interference.●
● ● When●changing●input●sensors,●power●off●the●controller●
first.●Connect●input●sensors●as●specified●and●supply●
the●power●again.●Then,●change●&●download●related●
parameters●using●PC●loader●program.●
● ● Use●(-)●driver●screws●(2mm)●or●use●plastic●driver●screws.●
If●not,●it●might●cause●product●damage.●
● ● Twist●Pair●wires●must●be●used●for●communication●cable.●
Connect●Ferrite●Bead●at●each●end●of●line●in●order●to●
reduce●the●effect●of●external●noise.●
● ● Avoid●installing●the●unit●with●overlapping●communication●
line●and●AC●power●line●together.●
● ● Draw●a●draft●while●using●the●controllers.●In●case●of●
installing●at●a●closed●area,●please●take●measures●for●
ventilation.
● ● Installation●environment
It●shall●be●used●indoor.
Altitude●Max.●2000m.
