Skycoded Control Module CM1
Skycoded Control Module CM1
The Skycoded Control Module (CM1) is a flexible
control system, which provides high-side switched
outputs for the valves and contactor, proportional
outputs and pulse width modulated (PWM) outputs
for the pump/motor, and low-side outputs for indicator
lamps, etc. It also provides active-high inputs from
operator controls and analog inputs from joysticks
and sensors. The control module has specific Skyjack
software and flashed memory for use with load
sensing and overload prevention.
Due to its integral tilt sensor, the control module is
mounted securely below the base at the center of
the machine, and can be located by swinging out the
hydraulic tray.
Factory calibrations for height, load, and level are
completed at Skyjack and only needs to be adjusted if
a major component (i.e. the control module, etc.) has
been replaced.
