Clockwise calibration - Press the button greater than 8 seconds if you are going
to calibrate using a clockwise rotation from the 4ma position to the 20mA
position. (LED will start flashing a 5 - 2 code indicating that calibration mode is
active and the unit is waiting to calibrate the 4mA position).
Step 3: Rotate valve to the desired position corresponding to 4mA. (This
can be the open or closed position)
Step 4: Press and release the button to capture the 4mA value (The LED
will start flashing a 3-3 code indicating that the unit is waiting to
calibrate the 20mA position)
Step 5: Rotate valve to the desired position corresponding to 20mA (This
will be the position opposite of the position in step 3)
Step 6: Press and release the button to capture the 20mA value (The LED
will turn on continuously)
Pneumatic Hookup Procedures
Prior to connecting the supply air to the spool valve, flush the system to re-
move any debris or contaminates. Galvanized pipe can easily flake and con-
taminate the system and therefore is not recommended. A 50 micron point of
use filter at every device is recommended.
