Slew Limitation - PROLEC Liftwatch Rail Operator's Manual

6.2 Slew limitation

Setting a slew limit
Liftwatch Rail offers two types of slew limitation, a virtual slew 'wall', or two angular limits. With the key switch in the
Set Limit position, access slew limiting via the LIMIT key and the screen will change as shown below.
Slew limiting is not active during this operation, if enabled, the system will still physically prevent height movement
when that limit is exceeded and will continue to monitor backward stability conditions. RCI remains fully functional,
however, the external blue lamp will be switched off.
Using a slew 'wall'
A virtual slew wall is a line parallel to the
centre line of the machine. Use the left/right
keys to move the 'wall' to the required position.
The value given in the info pop-up box is the
lateral distance from the machine centre line to
the bucket pin. Press exit to save the settings
and return to normal operation.
Once set, the system will not allow the bucket
pin or the left / right extremes of the counter
weight to cross the 'wall' line.
Note: The system is unaware of tool width,
monitoring is to the centre of the bucket pin -
wide tools will breach the line before the
motion can be cut.
