Wiring the Valve Controller
For a single APEX-S controlling one valve, see diagram on page 15:
1. Connect power and ground to the controller. Use 1 amp fuse for 12v (0.5 amp for 24v)
on positive controller leads.
2. Connect CAN wiring from the APEX-S to the valve. See Wiring Diagrams on the
following page for pin positions and wire colors for wiring a APEX-S.
3. When done there should be continuity between the CAN LOW contacts (Yellow wires
in connector position A), CAN HIGH contacts (Green wires in connector position B),
and CAN SHIELD contacts (Black wires in connector position C) throughout the entire
CAN communication wiring harness.**
For two APEX-S controllers to be controlling one valve, see diagram on
page 16:
1. Connect power and ground to the controllers. Use 1 amp fuse for 12v (0.5 amp for
24v) positive controller leads.
2. Connect CAN wiring from the first APEX-S to a CAN splitter at the valve and then onto
the second APEX-S.
3. Replace the terminated CAN leads going to positions 11 &12 in valves 12 pin connector
with the non-terminated version - Cable D. Plug the triangular connector into the CAN
splitter as shown.The wire length from one APEX-S to the other should not exceed 131 ft.
(40 m) when added together.
4. When done there should be continuity between all CAN LOW contacts (Yellow wires
in connector position A), CAN HIGH contacts (Green wires in connector position B),
and CAN SHIELD contacts (Black wires in connector position C) throughout the entire
CAN communication wiring harness.**
NOTE: ** CAN Shield (black wire connector position C) stops at valve connector

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.
4.Press the CLOSE button to move the cursor to the next digit for the second digit to be entered.
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.

Maintenance Instructions
Preventive Maintenance
The control system should be inspected during each apparatus check. Inspect the valve
controller, wiring, and valve for damage.
• Operate all possible functions to ensure that each works normally
• Fully open and fully close valve to check for full range operation
• During valve check, inspect rotation for smoothness and seats/seals for leaks
• Inspect all exposed wiring for signs of damage

19
OPERATION
On power-up the valve controller will be in the normal operating mode.The green OPEN, red
CLOSE, and yellow PRESET buttons will control valve position.The yellow PRESET button will set
the valve to a programmed position. Once a preset position has been programmed, pressing the
PRESET button will move the valve to that position.
The red LED will be on when the valve is in the fully closed position. The 10 green LED indicators
will show the valve position. Each LED indicator signifies 10 percent of the valve position.When
the valve is in the fully open position, all 10 of the green LEDs will be lit.
All information is supplied to the controller from the E14X or E16X electric actuator on the CAN bus.
