Access is an integrated aerial work control
system to control the entire functionality of aerial work platforms
including variable lift, lower and traction. The three modules of the system
are connected simply and easily to enhance machine capability and reduce
installation errors.

The Access Control System consists of a
minimum of three modules as follows:
The Joystick Module (JSM)
The JSM enables selection between Lift/Lower and Drive
at the touch of a button, then precise positioning of the platform is achieved
by variable joystick control.
The Joystick Interface Module (JIM)
If a larger, external joystick and user switches are
preferred, then the Interface Module provides all the connections to these, while
still providing the same display functions as the Joystick Module. The
electronics are 'potted' for maximum environmental protection and the
integrated gasket ensures the panel into which the module is fitted remains
fully water-proofed.
The Traction Module
The Traction Module has two 100A peak variable speed
outputs for permanent magnet motors, plus two associated outputs for
electromagnetic brakes. The module connects to the Ground Control Module via a
serial link, for simple, hassle free wiring.
The Ground Module
This forms the hub of the connection system, simplifying
the wiring harness. This module connects directly to the system batteries and
provides the high current, variable speed output for the hydraulic pump motor
along with the lower current outputs such as a variable down valve, alarm, horn
and beacon. All input switch wiring for pothole switches, elevation or
auxiliary inputs is also connected here to ease servicing of external parts.
The Ground Module features On-Board Programming(OBP), to
allow service engineers and OEMs to adjust parameters and view information for
all three system modules without the need for additional hand-held or PC
programming tools. OBP is accessed via a key press sequence on start-up, the
level of access allowed is determined by the passcode sequence entered and is
customisable for each OEM's requirements. Entering the service engineer
passcode allows editing of a limited number of functions only, whilst the OEM
passcode allows editing of all system parameters.
