Split Air Actuator
Disconnect actuator from
extension harness here.
Connect both leads of
the switchbox to the
now open connectors.
The Actuator Switchbox is to be used for the troubleshooting of the spit air actuator on Air-Pro
planters as well as an aid in the proper installation of a replacement actuator if needed.
DO
NOT USE THIS TOOL AS A REPLACEMENT FOR INTELLI-AG CONTROL DURING
PLANTING!
The switch is a spring centered momentary switch. Moving the switch to one
side or the other will cause the actuator to rotate either clockwise or counter-clockwise. When
the switch is released it will recenter itself and stop actuator motion.
Actuator troubleshooting and replacement.
1. the actuator conatains an internal circuit breaker to protect the
motor in case of torque overload. To reset the breaker, umplug
the actuator for 20 seconnds and then reconnect. You should
see the glow of a red light in the clear dome over the arrow.
2. The range of trave for the actuator is 60 degrees. It contains
internal limit switches to hold it within that range. The cavity
in the valve housing allows the vane slightly more travel room
than that. Operate the actuator through its full range of travel
with the switchbox to ensure there is no physical interference.
3. The mounting hardware for the actuator is located in slots to
allow for adjusmtent. When installing a new actuator, leave
the mounting hardware loose until the final adjustment is made.
a. Use the switchbox to electrically rotate the actuator
to one end of its travel.
b. Manually rotate the actuator housing until you
feel the vane make contact inside the valve. Back
off just slightly and tighten the hardware.
c. Be sure to operate the actuator through its full
range of travel before disconnecting the switchbox.
Split Air Actuator Switchbox
Planter harness must be electrically connected to tractor for switchbox to function. If this is not possible, another
12VDC power supply needs to be connected to the tower connector of the switchbox harness (connector with only two
wires). Pin A of the two wire connector is power and pin B is ground.
