4.4.1.1 Main switch
When you press the main switch (vertical = ON), the ma-
chine is powered up and ready for operation.
NOTE
Working with and without electric re-
mote control.
• When the remote control cable is plugged into the
switching cabinet, the machine is switched on and off
via the green push button at the end of the remote
control cable.
4.4.1.2 Star feeder selector switch
There are two settings:
• 0 = OFF: This setting switches off the star feeder motor
and interrupts the material supply to the mixing zone.
• 1 = AUTOMATIC: This setting couples the star feeder to
the working cycle of the mixing pump. The star feeder
rotates as soon as the pump motor is switched on.
4.4.1.3 Start / stop button
1. Press the green start button (“I”) to start the mixing
pump.
2. Press the red stop button (“0”) to stop the machine.
4.4.1.4 Phase-change switch with locking button
The phase inverter adjusts the direction of rotation of the
machine to the power grid on site.
1. Set the main switch to “0” (horizontal).
2. Turn the phase inverter in the opposite direction of its
current position and hold down the locking button be-
low the phase inverter switch.
!
DANGER
The phase inverter may only be operated
when the machine is switched off. To do this, turn
the main switch to “0” (horizontal).
4.4.1.5 “Water supply” push button
This push button is used for the manual water feed.
• Pressing this button adds extra water to the mixing
zone if required. Keep the push button pressed until
the desired amount of water is added.
