fr–h

 will be displayed, the OPEN output will turn ON,

and the valve will start to open. Press the Display Key as soon
as the valve stops by the limit switch built into the motor. The
count value for the fully open position will be set.

3. Press the Display Key. 

fr–l

 will be displayed, the OPEN output

will turn OFF, the CLOSE output will turn ON, and the valve
will start to close. Press the Display Key as soon as the valve

for the fully close position will be set.

4. Press the Display Key. 

mot

 will be displayed and the CLOSE

output will turn OFF. The automatically set fully open/close
time will be displayed. Use the Up and Down Keys to adjust
the setting if required (value must be between 1 and 999 s in
the units of 1 s).

5. Press the Display Key. 

sl–l

 will be displayed and motor

calibration will be complete. Press the Level Key for at least
two seconds, confirm that 

in–t

WARNING

Never calibrate the motor during control operation. Make sure
that control operations have been stopped before calibrating.

Note:

1. The output mode cannot be changed in motor calibra-

tion mode.

2. If the fully open position is less than the fully closed posi-

tion, the value position will not be displayed and the dis-
play will show “

a––– 

” for automatic and “

m––– 

” for manu-

al operation. If a potentiometer is not being used for
feedback, press the Display Key at steps 2 and 3 without
regarding the position of the valve and then set the fully
open/close time. Here too, the display for value position
will show “

a––– 

” for automatic and “

m––– 

” for manual

operation.
