Operation of the machine is controlled by means of the three buttons on the panel positioned on the left-
hand part of the tank (Figure 4). The upper button is used to start the grinding motor, the bottom button is
used to control the coolant pump. The red button is used to turn-off both functions of the machine. The
machine is ready for grinding when the second button lights blue. When the grinding motor starts, the
first button lights green.
The grinding motor can only be started after the red STOP button has been pulled out. Direction of
rotation of this motor is controlled by an appliance monitoring the phase sequence. The motor is
protected against overload by a thermal protector fitted along with a fuse in the wiring box at the left-hand
side of the machine. The wiring box is marked with a warning sign.
Fig. 4
The thermal protectors are set to the nominal value of the motor current. Their setting can not be
changed without the risk of incurring damage to the motor. The thermal protectors are set to automatic
mode, which means that after they have been tripped, they will automatically reset into the operating
position as soon as the operating parameters have been reached again. If the thermal protection trips
repeatedly, the defect must be detected and repaired by a qualified technician.
The power cable is fitted with a plug that allows the phase terminals to be swapped. The electrical
equipment of the machine has to be checked and inspected regularly in compliance with EN 60 204-1.
