Problem
Cause / Solution
The poker is not working
1. Verify if there is current
2. Plug in bad conditions
3. Defective switch
4. Connections in bad conditions
The poker works correctly but it overheats
1. Check the poker in not working out of concrete
2. Verify the output voltage of the Poker
3. Bearing in bad condition or without grease.
The poker works slowly and it overheats
1. Verify the out put voltage and frequency of the Poker
2. Check the specifi cations of the extensions cables
The motor is noisy
1. Bearing are not in good conditions
Operation
GB
DO NOT
use damaged or worn out cables.
AVOID
heavy loads on the cables.
CAUTION
PUTTING INTO OPERATION
Switch on:
Through switching on the machine, the voltage and frequency will be booted up synchronously with the nominal par (soft start-up).
Thus, critical current strength at the point of switching on will be prevented.
NOTE:-
The Poker with integrated inverter can be connected to an electric generator aggregate under the following conditions:
·
The operating voltage of the generator must be in any loading case between 230 + 15%;
·
The machine must be operated alone on the generator aggregate;
· The manufacturer of the generator aggregate must permit the operation of consumers with condensers.
Switching off:
Switch off the Poker with integrated inverter fi rst. Only after that pull out the electric connector from the plug.
VIBRATING POKER CONNECTION TO POKER
The poker has a plug to connect the vibrating pokers.
1. Connect the Poker to the electrical supply, ensure that the connection is correct (specifi cation and condition of cable according
to standards of security).
2. To disconnect, switch off the Poker with the switch.
3. Finally remove the Poker plug from the electrical supply.
Connection possibilities:
Make sure the total current (A) does not exceed the out put current specifi ed in the electrical characteristic of the Poker.
EXTENSION CABLES
Use three phase cables with the appropriate plugs. If in doubt, consult a qualifi ed electrician.
RECOMMENDATIONS OF USE OF CONCRETE CONVERTOR
1. Choose the right size of poker for: the size of the job, the spacing of reinforcement, slump of the concrete and the mix design.
2. It is recommended to have an additional concrete convertor available.
3. Pour the concrete evenly, into the form work, in 300-500 mm thick layers.
Do not use the poker convertor to spread the concrete.
4. Vibrate the concrete systematically. Make 300-500 mm vertical insertions at
intervals of 8 - 10 times the tube diameter. Where possible, push the poker
convertor about 150 mm into the previous layer of the concrete, this will help
obtain the best level of bonding between the two layers.
The concrete has been thoroughly vibrated when the surface around the poker
is shiny and no large air bubbles rise to the surface of the concrete. This normally
takes 10 - 20 seconds at each location of the poker.
5. Withdraw the poker slowly so that the concrete can fl ow into the void left by the poker.
6. Do not push or force the convertor against the reinforcement. Keep a distance of
70 mm minimum from the walls.
7. Always remove the poker vertically, so the concrete fi lls the empty space again. Do not switch off until the poker is withdrawn. The
speed of removal is approximately 80 mm per second. When the convertor is almost out, extract quickly to avoid shaking the surface.
