General system description
The radio controller is connected to the RCL 5300 controller, which is the master controller in a
CAN bus network where the radio remote control system and the safety system of the crane are
communicating in an integrated system.
Depending on the system configuration, the radio controller can control different combinations of
crane and stabilizer functions as well as digital functions.
CAN proportional control of PVED electric activations
The CAN output in the radio controller is via the RCL 5300 controller connected to the PVED
electric activations of the Danfoss PVG 32 control valve, which are activating the individual crane
functions proportionally with the signal from the remote control levers.
Proportional voltage control of the PVE electric activations
The output terminals in the radio controller are via cables directly connected to the PVE electric
activations of the Danfoss PVG 32 control valve, which are activating the individual crane functions
proportionally with the signal from the remote control levers.
In 24 volt systems the proportional voltage control is adjusting according to the following values
6
⇐
12
⇒
18 volt. In 12 volt systems the voltage control is 3
⇐
6
⇒
9 volt.
Please note: The above control requires a radio controller with another type of hardware.
Proportional current control of the PWM electric activations
The digital outputs in the radio controller are via cables directly connected to the PWM (Pulse
Width Modulation) electric activations of the control valve, which are activating the individual crane
functions proportionally with the signal from the remote control levers.
All in all it is possible to connect 8 dual (A and B direction) PWM outputs.
Digital voltage control of ON-OFF solenoid valves (RC-controlled stabilizers)
The digital outputs in the radio controller are via cables directly connected to the solenoid valves of
the stabilizer control valve, which are activating the different stabilizer functions ON-OFF with the
signal from the control levers of the remote control box.
Combined radio remote control functions
The above-mentioned radio remote controls may be combined. Typically the CAN proportional
control of the Danfoss PVED electric activations is combined with the voltage control of the ON-
OFF solenoid valves on the stabilizer control valve.
Digital functions
The radio controller has 14 digital outputs for for example engine functions, horn, light tower as
well as other available functions.
