The harness on the MCK2500SX computer is provided with an additional cable,
ref.
(X) “Actuator”.
The contacts on this cable are normally under a voltage of
+12VDC. During sowing operations, when the computer activates the shut–off
devices on the right-side rows or on the left-side rows or on both sides to create
a “path”, the polarity on the
(X)
cable is reversed and becomes –12VDC.
Therefore, if necessary, cable
(X)
can be connected to a third electric motor
(max. 12V 2A) operated through a by-pass: every time at least one row shut-off
device is activated, the motor connected to cable
(X)
is also activated. N.B. If this
function is not required, insulate the connector on the cable
(X)
with a sheath or
with insulating tape.
Connect the power cable
(H)
(delivered in the box containing the computer)
directly
to the vehicle’s 12VDC battery. Connect the RED wire to the positive
terminal (+) and the BLACK wire to the negative terminal (-). DO NOT use
cigarette lighters or similar devices as connectors.
