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 Receiver/Controller 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 Receiver/Controller and your harness fuses).  As the power distribution is
complex, please contact OMNEX for information before changing the fuse ratings from
their original values.
