While mot is displayed, use the Up and Down Keys to set the fully open/close time to a value 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 is displayed, and then press the Level Key again for at least two seconds to display the process value and return to the initial display mode. Settings with a Potentiometer (with Valve Position Display) 1. Turn on power and press the Level Key for at least two seconds. sl–l will be displayed. Then press the Display Key until calb is displayed. This is the initial mode when power is turned on for the first time. 2. Simultaneously press the Up and Down Keys for at least one second. 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 Level Key for at least two seconds, confirm that in–t is displayed, and then press the Level Key again for at least two seconds to display the process value and return to the initial display mode. 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.
