Electrical connections

Make up all cable connections according to the cranes wiring diagram
Switch on the power and check the lamp comes ON, on phase fault relay U6, if not change two
phases on the incoming power supply.

Start up the crane

Start up the crane by releasing the Emergency stop button, turn the key switch and press the start
button on the right hand control box.

NOTE: When switching OFF the crane use the key switch and not the emergency stop stop.

Engage relay D1A, safety relay D1 and main contactor C1 should now switch ON in the electrical
panel.

In case the engage relay D1A does not activate, check the emergency stop button, the key switch,
all joysticks are in neutral position, no overspeed alarm and phase fault relay U6 is lit green.

In case the safety relay D1 does not activate, check the emergency stop button, over speed relays
U10, ultimate limits. An alarm text in the operator’s display will inform which function to check.

In case main contactor C1 does not activate, check for alarms in the operator display, check the
RUN LED is green on PLC U101, check the READY LED is green on the motor drive unit U108
and all the infeed modules U110 & U111.

Check the operator display whether any alarms are active. After rectifying a fault reset the fault on
the Reset button in the display or by restarting the crane.
