Changing the rotational direction
Caution!
Make sure to check the rotational direction of the sewing drive before
initial commissioning of the sewing machine!
Operating the sewing machine with the incorrect rotational direction
can damage the machine.
The rotational direction of the clutch motor (a three-phase motor) is
dependent on the three-phase mains connection and the method of
assembly used. In order to check the rotation before use, do the
following:
–
Connect the clutch motor. Establish equipotential bonding. Connect
the sewing drive to the mains supply.
(Refer to chapters 11.2 and 11.4.)
–
Turn the main switch on.
–
Press the pedal (or the motor's clutch lever) until the belt pulley
starts to turn.
–
The handwheel must rotate in the direction of the arrow.
If the sewing drive is turning in the false direction, then you must swap
two phases at the mains terminals for the sewing drive. Take the
following steps:
–
Turn off the main switch and unplug the mains plug!
–
Swap the positions of two of the three phase wires at the sewing
drive's mains connection.
–
Plug in the mains plug and switch on the main switch.
–
Re-check the rotational direction (refer to chapter 11.4.2).
