Figure 3 Receiver to Power Electric Circuit connection
The contacts of KSTOP1 and KSTOP2 (KSTOP1+KSTOP2=STOP) relays are in series
and must be connected to the main contactor coil circuit.
The K2/START is activated once the start-up command is held down.
The K1/SAFETY relay is a security relay which is activated when any of the other
function control relay are activated.
The receiver is a class II device, according EN50178, containing a functional earth
connection. A (in Europe green-yellow) ground cable is not recommended for this earth
connection.
The power supply and relays must be protected against current overload with convenient
electric devices, limiting the maximum input/ output current to their limits: 1A fuse is
provided in the receiver circuit board for power supply. 8A fuse(s) has to be provided in
the crane control panel for the for the output relays.
