Rockshaft Control Lever Mounting
The MT-3405M system provides two connection points for
the run/hold. For run/hold in stal la tions in the cab or near
the control con sole, it may be more prac ti cal to use the local
access con nec tor (GRAY tie) ex it ing the rear of the con sole.
For run/hold sensor in stal la tions on im ple ments, it may be
more practical to use the run/hold connector at the module.
A jumper cover must be installed on the unused run/hold
connection point or the system will always be in HOLD and
the boom control valves will not function.
The run/hold sensor cable has a black body and a GRAY tie
near the 3-pin M/P connector and mates with the module
cable having a GRAY cable tie near the 3-pin M/P connector.
Make certain that you install the correct sen sor cable and
connect it to the correct connector on the module. The run/
hold sensor has a BLACK body. DO NOT use a speed/flow
sensor (GREEN body). See wiring diagram on the previous
page. A jumper cover should be installed on the unused run/
hold connection point.
Attach a magnet to a lever or some part of the •
equipment that moves when the im ple ment is raised
and lowered. The Hall-effect run/hold sensor is sensitive
only to the south pole (side with dashed line) of the
magnet. Check the polarity of the magnet by bring-
ing it near the run/hold sensor with the console
turned on. Note and mark the face of the magnet
that is toward the sensor when the console does not
indicate “HOLD.” When the mag net is away from the
sen sor, the con sole will be in HOLD and will shut
off the boom valves and stop count ing acres.
NOTE: The run/hold kit includes a 5’ sensor cable and 10’
extension. You may re quire additional extension cables
which are avail able in 5 ft. (1.5 m), 10 ft. (3 m), 15 ft. (4.5 m),
20 ft. (6 m) and 25 ft. (7.6 m) lengths.
You may also use a toggle or other type switch. Sim ply •
cut the blue jumper wire in the dust cover and splice
on an appropriate length of wire to reach your switch.
When switch is closed, console is in RUN. When the
switch is open, the console is in HOLD.
NOTE: Do not apply power to run/hold wires.
