MAINTENANCE/CALIBRATION
!
Important:
All valves must have the position calibrated after installation.
NOTE:
If using an EB_J or EB_S butterfly valve refer to ”Valve Polarity“ in the Programming Mode
section on page 21. This programming must be done before performing the automatic valve position
calibration.
Automatic Valve Position Calibration for APEX-S
The valve position calibration determines the point where the valve is fully open or fully
closed. This process will automatically determine these points by running the valve to the fully
closed position then the fully open position, and then back to the fully closed position. This
calibration must be done after installation, when the actuator has been replaced, or in any
case when valve does not fully close or fully open.
NOTE:
These routines must be utilized so the position of the valve will be displayed accurately.
Valve Calibration (CODE 1113)
1 Turn on power to the valve and controller(s)
Enter Code 1113
2 Press and hold the CLOSE button; then press and hold the OPEN button After 5 seconds, the red
CLOSE LED will flash Code 1113 can now be entered
3 Use the OPEN button to set the first digit of the code 1113 Press the OPEN button once, one
green LED on

Press the OPEN button once, one green LED on
5 Press the CLOSE button to move the cursor to the next digit for the third digit to be entered
6 Press the CLOSE button to move the cursor to the next digit for the fourth digit to be entered
Press the OPEN button three times Valve calibration begins approximately 4 to 5 seconds after
the last digit is entered for Code 1113
7 The valve will move to the closed position, calibrate to the closed position, then move to the open
position, calibrate that position and then return back to the closed position and stop While the
valve is calibrating the LEDs on the controller will turn on and off on at a time from left to right
When calibration is complete all 11 LEDs will flash several times and then the red closed LED will
stay on solid The valve is now position calibrated
