OPERATING INSTRUCTIONS
For Electronic Polarity Reversing Control Units
WORKHOLDING AND AUTOMATION
All persons, operating, using or maintaining the electronic control-unit have to be qualified
and have read the operating instructions carefully. It is not only necessary for proper
operation it is important for your safety.
To prevent dangers caused by electric current, mounting and installation is only allowed to
be done by licensed electrician.
The polarity reversing control-unit is designed only for use with SAV magnetic chucks.
The type of chuck can be selected at the front of the controller. Changes are possible by
trained personell after consultation with manufacturer. For use of electro permanent
magnetic chucks, it is important, that the cycle-time between two on/off-cycles is not less
than 3 minutes.
The control-unit works with high direct and alternating currents. Before maintenance,
it is essential to disconnect the electrical power supply. Before connection of chuck, the
connection of mains-voltage and the setting of magnet type has to be checked.
The operator must ensure at installation, that coding of controller is corresponding to the type
of magnetic chuck. A wrong presetting of controller can damage the chuck (see chapter 2.b.3).
It is not allowed to use the electronic polarity-reversing control-unit with no protection.
The international protection (IP) has to be considered. In case of no protection, there is the
danger of electric shock. All units must be grounded.
To prevent failures and hazards, it is important for the operator to be properly trained. The
operator is responsible for any other people within the working area. The operation for
several products has to be previously read and followed. The factory management has
to make the operating instructions and manuals accessible for the operator and has to
ensure, that the instructions are read and understood by the operator. For this, also refer to
operating instructions of magnetic chuck or sine table.
