Operation - override 

When the system is in a overload condition certain equipment motions will be disabled. Condition No 4 shown on the previous page has 
all motions disabled. To allow the machine to be moved to a safe position the motion control can be cancelled. To override the system 
press the MODE button. The red LED and the internal and external alarms will still operate, but hydraulic control will be released. The 
system will automatically cancel the override function when the machine reaches a safe position. 

Operation - low pressure 

The measurement of hydraulic oil pressure 
in the boom lift cylinder is crucial to the 
operation of the RCI. In the event of low 
pressure being detected the message 
shown here will appear, the amber LED will 
illuminate, and the internal alarm will sound. 

This condition can be ignored it the 
equipment is resting on the ground as low 
pressure under this circumstance is normal.
