Each of the eight operations that are controlled by the two joysticks and the eight valves are

1st Boom – The first section of the Telescopic Boom of the Hydraulic Crane extends to get the load near to it intended destination

2nd Boom – The second section of the Telescopic Boom of the Hydraulic Crane extends to get the load directly above its intended loading/unloading destination

Slewing – This controls the rotation of the crane boom to enable the operator to point the boom in the correct direction

Support Leg Left – This will stabilise the crane on the left side and is deployed before any lifting begins and retracted after all lifting has been completed

Extension – The enables further extension from the crane to give a high level of accuracy

Grapple – With this configuration a grapple is included for the forestry application of lifting and moving timber logs

Support Leg Right - This will stabilise the crane on the right side and is deployed before any lifting begins and retracted after all lifting has been completed

Rotator – The rotator controls the angle and direction of the grapple in order to position it directly above the intended loading/unloading point

2 x Joystick controllers each with forward and reverse, left and right positions in additional to buttons to adjust each specific function to the operator’s specific needs

8 x Function Hydraulic Valves each configured with specific flow rate to suit the required functions.

CANBus card for analog/digital inputs.

DESCRIPTION

MDCi is an electronic board with CANBus interface to

simulate 2 JC joysticks with 2 Otto joystick and push button dashboard.

The transmission has course immediately after the turning on of the

electronic card.

FEATURES

- supply voltage from 10 to 30 Vdc

- CAN V2.0B communication bus

- 120 Ohm inner terminator not present in this version

- 2 diagnostic LEDs (red and green)

- firmware updatable by integrated serial port

SIGNALS

Red LED flashing one time: short circuit error on the +5V stabilized output

Red LED flashing two times: one of the analog inputs has been found not at rest position during the turning on, this

input is blocked until a reset.

Green LED On: the electronic card is working correctly.

The green LED flashes one time every time an input (analog or on/off) change status.

MDCi contro unit for OTTO joystick interface
and button panel for Forest Crane
Mounting version: X1

NOTE:
to have the cable L = 1.5m it is necessary to
- make the joystick / cable connections 7x0.75mmq by removing the
original connector
- put the corrugated sheath and fix it to the bottom of the joystick (see photo)
- connect the 7x0.75 cable to the Deutsch 6-pin female connector
to male contacts
