Electrical configuration

Printer-friendly versionPDF version

The three electrical parts described in this chapter are the cable, the electrical cabinet and the Remote Control Unit (RCU, pic 1).

Each of them may be installed in different combinations. Those combinations are chosen following the client’s need and the tank configuration.

Cable by the bottom

In Rescue & Survival training pools and in order to be able to remove completely the Wave Ball and its cable from the tank, there is no cable inlet integrated in the floor of the pool. The cable is passing over the freeboards and going directly to the electrical cabinet. If even more freedom is needed, the electrical cabinet can be placed on a trolley and the whole set can then be moved away to a stocking place.

WOW can also provide a quick connector (pic 4) on the Wave Ball cable. The Wave Ball cable can then be easily disconnected from the electrical cabinet and moved away while the electrical cabinet stays fixed to the wall for example.

 

However, in some situations when the cable cannot run on the beach, the cable can go to the electrical cabinet trough a pipe under the beach (pic 5); this solution has the disadvantage that the pool can not be easily free from the Wave Ball and the cable. Another easier solution is to pass the cable above the beach (pic 6).

In the water, the cable of the Wave Ball can follow the bottom of the tank (pic 7) or float thanks to buoys (pics 8 and 9). Most of the time, buoys solution is chosen because it spares precious meters of cable (if following the bottom, the length of the cable is too short to reach the electrical cabinet)

Now that we know how the cable is going to the electrical cabinet, we have to know what will be the electrical configuration. The electrical configuration will depend on the client’s need and field configuration.

Configuration 1 and 3

The transformer box and the main electrical box can be separated, this is useful when you can not reach the main electrical box or the technical room with the allowed length of Wave Ball cable. In that case, a smaller box, containing only the transformer, is placed closer to the pool. The box is then connected to the main electrical box with wires that can be up to 70m long or more on request.

Configuration 3 and 4

The remote control can be integrated to the main electrical box or not. It can be interesting to have it integrated when the electrical box is close to the tank in order to have all the parts together.

Note that configuration 1 and 3 with the separated transformer are the only ones available for Wave Balls above 150F; this is because the too heavy weight of the transformer obliges the separation into two boxes.

In addition to those configurations, the BETO or BOTO (if Wave Ball above W150F) can be ordered with the cable entry in four configurations for easier integration: side left/right, bottom left/right.

All the cabinets are called with a name under the form x1x2x3x4 where:

x1 =B Box
x2 =E Electronic : control and command electronic parts are assembled into the box
 O No electronic
x3 = T Transformer: safety power transformer  is assembled into the box
 O No transformer
x4 =B Buttons: commanding buttons are placed onto the box door
 O No buttons

Electrical configuration number 2 : Only the remote control is separated

 

As the RCU allows to start and stop the waves, it is necessary to place it close to the place where the operation chief manager will be. This is mostly important in order to have a direct access to the emergency stop button.

  • The distance between the RCU and the electrical cabinet can be up to 80m.
  • If the tank is outdoor, the RCU should be placed in a watertight housing.

Additionnal emergency stop (option)

If the RCU is far away from the wave site or without a direct view on the tank, an additional emergency stop button should be placed.

Siren (option)

The siren will give a warning when the waves session will begin: at each start of the Wave Ball, the siren flashes and emits a sound for a few seconds.

MIO (option)

This “Multiple Input/Output” box allows the control of the Wave Ball from an external device, different than the Wave Ball remote control. This external device can be for example a computer which controls all weather effects together (rain, wave, wind…).

The computer allows to start various weather configurations by mixing all the effects together with various parameters: quiet wind with small waves and no rain or high wind with big waves and heavy rain for example... Sequences and evolution of various climates are also possible.

As the Wave Ball is an electrical machine combined with the proximity of water, electrical safety rules have to be respected for the installation.

 
Fig 1 : Pool Safety Zone definition for electrical equipment installation (as described in CEI 364-7-702 standards):
Fig 1 : Pool Safety Zone definition for electrical equipment installation (as described in CEI 364-7-702 standards):
 

 

Depending on their position in the several zones described in the diagram (fig 1), it is possible to define electrical equipment as follow:

 

  1. First class equipment: electrical equipment which main insulation does not support protection against electrical shock alone. All the accessible conductor parts must be connected to a protecting conductor so that all the parts cannot become dangerous in case of main insulation failure.
  2. Second class equipment: electrical equipment which all accessible parts and active parts are separated by double insulation or reinforced insulation. This equipment does not include part to connect existing accessible parts to protect conductor.
  3. Third class equipment: electrical equipment in which extra low voltage protection is used against electrical shock.

 

  • Wave Ball is defined as a third class equipment. It can be used in zone 0.
    Wave Ball cannot be directly connected to earth.
  • The remote control is defined as a third class equipment. It is generally used in the second zone (see graphic above). RCU can not be directly connected to earth.
  • Main electrical cabinet and transformer cabinet
    These cabinets are defined as first class equipment and are thus placed outside the numbers 0.1 and 2 zone.

WOW Company respects a distance of 4m for the integrations of the main electrical cabinet or the transformer box.

The following figures will give you all the electrical specifications for each model of Wave Ball.
