4.1. MEC Override
The system can optionally be fitted with a key operated master override
switch. To access the master override switch, a tamper detection device
must be broken and the operation of this switch will be automatically logged.
Turning the switch to the override position will allow normal operation of any
of the hydraulic services regardless of safety status. When the system is in
override:
the external alarm (if fitted) will be active
the beacon (if fitted) will be off
the RED LED will flash
an ‘In Override’ message will appear on the display indicating that the
machine limiting is overridden.
The override state will automatically return to normal operating mode after 30
minutes (default value), regardless of the system status. The master override
key switch must be cycled to put the system back into override.
The master override key switch should only be used if the system is not
operational due to a fault and the machine needs to be moved due to its
location presenting a hazard.
