1.3  Use for the Intended Purpose 
The qSCALE i2 console is the interface of the Rated Capacity Limiter system (RCL).  
The RCL detects a crane overload status depending on various parameters.  
The crane operator is warned well before the onset of an overload status via visual and audible 
warning signals.  
Although the system has signal outputs to switch off the crane movements, this power-off is effec-
tive with corresponding external wiring.  
Although the system incorporates functions for monitoring adjustable geometrical limit values with 
visual and audible warnings and a relay output in the event of limit values being exceeded, the 
system cannot be used as an operational limit switch. 
The crane operator is responsible for the safe operation of the crane.
