There are two separate power (+12V) and ground pins on the Main Connector. If
you are using the old-style Output Cable or are making your own wire harness, the two
ground pins (A and AF) should be connected to a good ground point at the battery or on
the chassis. The two power pins (AG and B) should be connected to a good switched
source, usually at the vehicle’s PTO switch. While the Controller/Receiver contains
internal fusing, it is highly recommended that in-line fuses be used to protect the wiring
harness in case of short circuits; use a 3A fuse for pin AG, and a 15A fuse for pin B.

The Dump Valve Output (pin C) is a safety feature, and must be used to control a
dump valve in the hydraulic pressure circuit. Whenever this output becomes de-
energized, the dump valve must divert the hydraulic flow back to tank so that all
hydraulically-powered movements stop. Only when this output is energized (driving
+12V out) should the machine have hydraulic power.

The rest of the output functions except for the Electronic Throttle Output (pin e)
are designed to drive either proportional or on/off solenoids at up to 3A each. Note that
the total simultaneous load must not, of course, exceed the ratings of the power fuses
(both inside the Controller/Receiver and your harness fuses). As the power distribution is
complex, please contact OMNEX for information before changing the fuse ratings from
their original values.

To control the engine throttle, use pin e for electronic throttles which take 0 to 5V,
or wire pins b and c to direction-control relays for motor-driven throttles.
The Switch Inputs (pins m, n, p and q) are best switched to the +5V Power
supplied from pin r, although they will work fine if switched to +12V. The +5V from pin
r is preferred because it is already protected against short circuits. Do not feed +12V
back into pin r.

back into pin r.
The proportional sensors must be powered from pin s (+5V) and pin w
(ground). Do not power them from +12V or any other ground.
