1.-4. Conditions for Use
The HIGH FREQUENCY transmissions are designed to vibrate concrete and be used under the hardest
conditions, both environmental as well as use.
The vibrating needle are equipped with a powerful motor encased in EPOXY resin, protecting the from
vibration.
All the models VAF-, are factory-equipped with thermal protection against over-heating. When the
system detects an increase of temperature over the predetermine levels, the needle stops automatically.
One has missing the conditions that have produced the stopping the starting is automatic.
The vibrating needle are protected by a thermal system, the stopped for the needle doesn't mean a fault,
only when the vibrating needle is into the concrete, probably exist a fault.
If the stopped is produced with the needle out of concrete, its not an fault, is simply a natural protection.
The transmissions' needle of HIGH FREQUENCY must be submerged into the concrete as a minimum
two third parts, to facilitate its cooling.
Avoid the vibrating needle working in contact with solid and ridged prominent objects for long periods of
time.
The needles without thermal can't be out of the concrete more than 5 minutes, for avoid a possible
damage of the winding.
In case that the stopping will be produced with the needle into the concrete and vibrating it, the
equipment must be stopped immediately. It will be check and repair if it is necessary. Under any
circumstance, continue vibrating, because it produced the breakdown in the needle motor.
