4 Operating and Hazard Situation Recommendations
Operating Recommendations
When using envelope monitoring:
When setting a slew and or height restriction, make sure any implement attached is

in its least favourable position
Check for correct operation once the restriction or restrictions have been set

Reduce operating speed

Do not move the equipment quickly when close to a restriction

Do not operate the machine in a reckless manor

Do not travel with a restriction set

Reset the slew restriction if the machine is relocated

Hazard Situation Recommendations
In a limit hazard state:
Return the control levers to neutral once a limit has been reached if appropriate

Operate the machine at a slow speed

Do not travel


4.1 MEC Override

The system can optionally be fitted with a master override key switch. Turning
the key to the override position will allow normal operation of the hydraulic
services regardless of safety status. When the system is in override, the ex-
ternal alarm (if fitted) will be active, and the beacon (if fitted) will be off, the
RED LED will flash and an 'In Override' message will appear on the display
indicating that the machine limiting is overridden. The override state will auto-
matically return to normal operating mode after 30 minutes (default value),
regardless of the system status. The master override key switch must be cy-
cled to put the system back into override.
The master override key switch should only be used if the safety system is
not operational due to a fault and the machine needs to be moved due to its location pre-
senting a hazard. The override status is recorded in the system data log. To access the
override key switch an anti tamper seal may need to be broken.
