functions, for in-going signal handling e.g. overload and lift reduction functions and for serial
communications if more than one electronicbox is used in so called tandem operation. The
cable has a circular type contact (Amphenol / Hirchmann) at one end.

The crane emergency stop box is a separate unit for fixed mounting on the vehicle. The crane
emergency stop box must
be connected between the vehicle battery and the electronicbox.
• When an emergency stop is activated the main power supply to the entire remote control
system is disconnected.
• The crane emergency stop must be suitably located and easily accessible.
• Before operation is started, the driver must inform all fellow-workers about the emergency
stop function and its location.
With the electronicbox switch in MANUAL position and an electric dump valve, the emergency stop
function is also available during manual hand lever operation.
