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
