USB Connector
The RDM and ODM each have a USB Connector
(4, Figure 3-14) located immediately below and to the left of
its related display module screen.
The USB Connectors allow a service technician to connect
to the display modules and update its software or download
the data logger from the RDM, which records certain events
that can occur when operating the crane.
NOTE: These USB Connectors are not powered and will
not charge a phone or tablet.
RCL Shutdown Warning Indicator (Non-CE
Certified Cranes)
The RCL Shutdown Warning Indicator (5, Figure 3-14) is
located immediately below and to the right of the RDM
screen.
The RCL Shutdown Warning Indicator comes on (red) when
the RCL senses a lift that is greater than 100% of crane
capacity for the programmed configuration.
When the RCL senses a lift that is greater than 100% of
crane capacity, the crane control system will lock out the
boom up/down, telescope extend, and hoist up crane
functions, which would worsen the overload condition.
RCL Shutdown Warning Indicator (CE
Certified Cranes)
The RCL Shutdown Warning Indicator (5, Figure 3-14) is
located immediately below and to the right of the RDM
screen.
The RCL Shutdown Warning Indicator comes on (red) when
the RCL senses a lift that is between 100% to 110% of crane
capacity for the programmed configuration.
When the RCL senses a lift between 100% to 110% of crane
capacity, the crane control system will lock out the boom
up/down, telescope extend, and hoist up crane functions,
which would worsen the overload condition.
RCL Early Warning Indicator
The RCL Early Warning Indicator (6, Figure 3-14) is located
immediately below and to the right of the RDM screen.
The RCL Early Warning Indicator comes on (amber) and the
buzzer will repeatedly come and go off when the RCL senses
a lift that is between 90% to 100% of crane capacity for the
programmed configuration.
Anti-Two-Block (A2B) Indicator
The Anti-Two-Block Indicator (7, Figure 3-14) is located
immediately below and to the right of the ODM screen.
The A2B Indicator comes on (red) when a two-block
condition occurs.
When a two-block condition occurs, the crane control system
will lock out the hoist up, boom down, and telescope out
crane functions, which would worsen the two-block condition
if operated.
