Operating Instruction
The Hydrovar-
the control element in the event of a fault, whereby the motor has zero current
but remains energized and comes to a halt. The motor can also be halted by
mechanical blocking. If it is electronically switched off the motor is disconnected
from the mains voltage through the electronics of the Hydrovar-
but is not potential-free in the circuit.
In addition voltage fluctuations, especially power failures can cause the system to switch off
itself.
Repair of faults can cause the motor to start up again!
The system may only be put into operation when it has been earthened. In addition,
equipotential bonding of all pipes must be ensured.
The operating instructions must be read, understood and followed by the operating personnel.
We point out that we accept no liability for damage and operating disorders which are the
result of non-compliance with the operating instructions.
