7.9.2 Levelling Function Connections
MFI1: For the levelling function MFI1 (or MFI2) can be used. For the desired function the parameter
setting must be 4-1-1 MFI1 oper. (or 4-2-1 MFI2 oper.) = Level
Single hoist selection: The switch must be closed if only one of the hoist is run without the levelling
function. If the switch is open (as in the drawing) the hoist request is forwarded directly to the MFI1 and
through the levelling limit switch to HIN.
Limit switch: When the hoist reaches the levelling limit, the switch cuts off the HIN line resulting the
hoist to stop in the normal way. MFI1, however, still has the hoist up request and it forwards this
information to all other units through the CAN bus so that they can continue hoisting until they also reach
their levelling limit or the hoist up request goes off.
