    561383-002 Issue 1.1 1.2 Height Limiting The EA Heightmaster+ provides accurate monitoring of height and will alarm and cut motion at a user definable height or by selecting one of the two predefined height limits of 3.7 and 4.6 m. These are indicated on a lamp bar. EA Heightmaster + 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 height limit from being exceeded.
