1.3 MIN Radius Limiting (Cab Protection)
The Min Radius Limit limits the bucket pin from entering one of two predefined minimum radii. EA Height uses a COMBI BOX
(see section 2.0) which allows the system to interface with hydraulic solenoid valves on the pilot control circuits to physically prevent
the Min Radius Limit from being exceeded. The Min Radii Limits are stored in the memory each time it is set. When the system is
switched on, the last Min Radius Limit selected will become operative. The yellow LED on the display is lit when the bucket radius is
selected and the green LED is lit when the attachment radius is selected. This function cannot be cancelled or adjusted by the opera-
tor. True Height and radius are given with telescopic section equipped machines.
1. Constantly monitors the bucket pivot pin radius
The EA Heigh :
3. Provides the user with a clear display of alarm conditions.
2. Motion is cut to prevent equipment from entering excluded zones
4. Allows two preset Min Radii Limits (Bucket and Attachment) to be
set from the safety of the cab via a key switch.
