7. Switching between REM (Remote) and LCL (Local)
Remoteandlocalswitchingcanbeperformedusinganyofthefollowing:
(1)Contactinput,(2)Parameter,(3)Communication,and(4)Userfunctionkey.
LCL (Local)
Controlisperformedusingthetargetsetpointsetonthecontroller.
REM (Remote)
Controlisperformedusinganexternalanalogsignalthatisusedasthetargetset-
point.Thefollowingshowsan exampleofswitchingfromlocalto remoteusingthe
parameter.
Fordetailsofotherswitchingmethods,seeUser’sManual(IM05P01C31-01EN).
•ThePIDgroupforthelocalSPnumberisusedasPIDinremotemode.
NOTE
WhenthecontactinputisON,operationcannotbeperformedusingtheparameter,
communication,orkey. Whenthecontactinput isOFFandthe settingisswitched
usingtheparameter,communication,orkey, thelastswitchingoperationis per-
formed.

8. Manipulating Control Output in Manual Mode
NOTE
Inmanualmode,controloutput ismanipulatedbyoperatingthekeys (thevalueis
changedusingtheUp/Downarrowkeys,thenoutputtedasitis).
EveniftheSET/ENTER keyisnotpressed, thecontroloutputvalue changesac-
cordingtothedisplayedvalue.
Instopmode(whentheSTOPlampislit),controloutputcannotbemanipulated.
MAN lamp is lit.
Up arrow key: increases control output.
Down arrow key: decreases control output.
In Position proportional control:
Up arrow key; opens the valve.
Down arrow key; closes the valve.
Output; only while pressing a key.
OUT; valve opening (0-100%)
Output manipulation in Position proportional control
is not restricted from output limiters (OH, OL).

* The LCD (a liquid crystal display) is used for
a display portion of this product.
The LCD has a characteristic that the display action
becomes late at the low temperature.
Additionally, the luminance and contrast degradation
are caused due to aged deterioration.
However, the control function is not affected.
■ Remedies if Power Failure Occurs
during Operations
• Instantaneouspowerfailurewithin20ms.
 Apowerfailureisnotdetected. Normal
operation continues.
• Powerfailureforlessthanabout5seconds,
