Health and Safety
GB
For your own safety, as protection for others, and to avoid damage to the motor, read carefully the following usage
recommendations.
· For the safe and proper operation of the ‘‘Vibratronic’’,
make sure
that operators have been instructed in the correct use of this
machine.
· Before connecting the motor to the electrical system,
make sure
that the voltage and frequency match with the ones stated on
the machine serial plate.
·
ENSURE
that all housing screws are tight before starting work.
·
AVOID
the fl attening of the cable by heavy machinery with could cause breakage.
·
DO NOT OPERATE
the motor when this is working and without transmission.
·
DO NOT WORK
poker in bad conditions, the motor overheats.
·
DO NOT WORK
with the cast housing broken.
·
DO NOT PERMIT
untrained personnel to operate the motor or connections.
·
MAINTAIN
free ventilation of air.
·
KEEP
the Poker in a clean and dry area.
·
MAKE
SURE
that the electrical cable is with the proper section and functioning properly.
·
BEFORE DOING
any type of repair,
DISCONNECT
the Poker from the electrical system.
·
WHEN FINISHING
the job or when taking a break, the operator should unplug, disconnect it from the electrical system, and have it
placed in such a way that it should not fall or tip.
·
Pokers with an integrated converter must only be connected to the voltage and frequency indicated on the power rating plate.
Rating plates can be found on the outside and inside of the inverter chassis.
·
The machine must only be operated when all protective devices are in place.
·
The use of Vibratronic Pokers is not permitted in an environment where there is a danger of explosions.
·
Ensure that all parts of the machine are bolted and secured before operating.
·
In addition, all local regulations should be respected.
Vibration
Some vibration from the poker is transmitted through the fl exible hose to the operator’s hands.
PPE (Personal Protective Equipment).
Suitable PPE must be worn when using this equipment i.e. Safety Goggles, Gloves, Ear Defenders, Dust Mask and Steel Toe capped
footwear. Wear clothing suitable for the work you are doing. Always protect skin from contact with concrete. Suitable ear defenders
Should be used.
Measure to ensure the EMC
The machine fulfi ls all requirements for industrial use with regards to interference immunity and interference emissions, as long as all
measures in the Operators Manual are observed.
Grounding and Potential Equalisation
The correct and proper grounding assures the protection of people from dangerous voltage points (entry, exit, and intermediate circuit
voltage) and through the leakage of parasitic currents and the low impendence potential equalisation it is an important instrument for
the reduction of electromagnetic infl uences.
Filtering
Filters are fi tted into the transmission path between the source of interference and the susceptible device. Their function is to reduce
the emissions from conductors and to increase interference immunity. For this reason the machine is fi tted with net fi lters and throttles.
Shielding
It serves the un-coupling of fi elds between two spatial areas. It helps to reduce the emissions of electromagnetic radiation and
increases the interference immunity. The consistent use of metallic chassis is one of the most important measures to assure EMC.
Linking into motor conductors.
The inductive input-coupling in an electric circuit can be reduced considerably by using twisted conductors. Capacitive, inductive and
electromagnetic input-couplings must be reduced by using shields for the cables. Only such shields used on both sides will reduce the
inductive and high frequency electromagnetic input-coupling.
General Safety
GB
Before operation
Intended use:
· The Poker must only be used for the intended purpose, which means for the compression of concrete of various
consistencies. Any other type of use is not in accordance with the intended use and is therefore the sole responsibility of the
respective
company.
· The frequency inverter is a voltage source inverter (VSI) with fully digitalised microprocessor technique. It works in pulse width
modulation (PWM), which assures the trouble-free run of connected equipments. IGBT (Integrated Gate Bipolar Transistors) reduce
the power dissipation (moderate warmth develops) of the transient loss in the power unit.
·
The new CCDS-system (Current Control Dynamic Scan) will not permit a switch-off of the frequency inverter in the case of an
over
load.
· Another protection for the frequency inverter is the short circuit immunity.
· An integrated motor-protection (I x t) and software-adapted limitation of the current offer a high protection for the drive.
· EMC is an important criterion and therefore we use an aluminium chassis as protective umbrella as the best protection against
interference immunity and interference emissions.
· Integrated entry- and exit fi lters are standard.
· The machine corresponds with protection class 1 (earth wire).
