Start-Up, Mpi-System, Adjustment Of The Rotation Speed, Thermo Protection - ALFRA ROTABEST 40 RL-E Manual De Instrucciones

START-UP
You receive a completely assembled magnetic core drilling machine and detailed operation manual. Please
check the condition of the goods on receipt for any transport damage, and make sure the delivery
is complete. Otherwise contact the manufacturer immediately.
!
Always read the operation manual before using the device for the first time!
1. First, check the cable and plug for damage, then insert the plug in the mains socket.
2. Push button MAGNET ON, in order to initiate the magnet and the magnetic adhesion is guaranteed.
3. When working on walls and ceilings, secure machine with safety belt.
For these operations we recommend cooling with our spray ALFRA BIO 4000, Prod.- No. 21040.
4. Push the button MOTOR ON to start the Motor.
5. To switch off the machine proceed in reverse order, first MOTOR OFF, then MAGNET OFF.
MPI-SYSTEM
• At function „magnet on", 100% of the magnet power is available right from the beginning.
• Simultaneously a timing relay will be activated which is preset to 60 seconds. If the motor will not
be switched on after "magnet on" the LED of the magnet switch on the key pad is flashing and a buzzer
sounds at the same time. This time-controlled alarm will be also activated after drilling is done and the
motor is switched off but the magnet is still on.
• A functional check of the LED and of the buzzer is carried out if the machine will be connected to
the mains with the electric cable (short flashing of the LED and short buzzing). With it it is possible to
test the model in use respectively the control in use fast and easily on site.
• The new PCBs are 100% compatible with machines of older type series, i.e. in case of repair they
can be replaced respectively exchanged without problems.
ADJUSTMENT OF THE ROTATION SPEED
The machine has one gear with 4 mechanical reduction stages and a full-wave electronic.
At first you need to adjust the correct mechanical adjustment. Afterwards you need to adapt the rotation
speed with the help of the electrical rotation speed regulator.
If it's possible always choose the adjustment with low gear shifting and high engine speed.
Then the motor is set at a high torque and therefore it's protected against overheating due to high load.
THERMO PROTECTION
The thermo protection stops the motor when it's overheated automatically.
Afterwards you need to let it run with a high rotation speed at the idle speed for about two minutes.
