The three polar meters K1 and K2, are equipped
by a mechanical security (Fig.65) to avoid the
starting of both meters simultaneously saving the
motor from blowing up.
On Ce proved machined the chuck motor is also
equipped by a thermostat R1 connected to K1 and
K2 (Fig.18): in case of overheating it disconnects
K1 and K2 automatically.
When the chuck motor is cold the thermostat gets
closes and K1 and K2 are reactivated
automatically.
All King 5600R are also equipped by a safety
micro switch S7 on the Robotic assy that locks all
hydraulic movements, except the toolholder lifting
and lowering, whenever the toolholder hook is not
well clamped.
5.0 ACCESS TO ELECTRIC PARTS
BEFORE APPROACHING THE
ELECTRIC PARTS OF THE
MACHINE, DISCONNECT THE
MACHINE FROM ELECTRIC

Very often electric failures are only caused by
loosened wires or connectors not well fitted.
Therefore it is VERY IMPORTANT BEFORE
STARTING WITH ANY CONTROL AND/OR
REPLACEMENT VERIFY IF ALL WIRES AND
CONNECTORS ARE WELL FITTED.
To access to electric parts of the machine:
