Check direction of rotation
Check the direction of rotation of the motor by switching it on briefly (jog
mode).
The FAM requires a clockwise rotating field at the connecting socket.
NOTICE
Incorrect phase sequence / rotation direction of the motor
The pumps will be destroyed.
►
In jog mode, check the direction of rotation of the motors.
►
A rotation direction arrow on the fan cover of the motor identifies the
correct direction of rotation.
Make sure there is a clockwise rotating field. If this is not the case, then the
phases can be rotated in the 16A / 32 A connection plug with the aid of the
phase changing switch in the plug. For the 63A version, the two phases must
be switched on the terminal block S0 (e.g. L1 and L2).
Prior to start up, ground the FAM using equipotential bonding.
Prior to starting up the FAM, connect the ground bond to the FAM
and the tank to be cleaned.
Check the connection between the tank, the FAM and the ground
potential for good conductivity.
