The Switch® Pinsetter uses 3-phase power on all motors. Local Voltage and Frequency (380V/50 hertz, 415V/50 hertz, 220V/60hertz, etc.) must be established before the order is placed. The Electrical Installation of the Switch® Pinsetter is designed to be simplified, since one 5-core cable per pair of lanes is all that is required for the Pinsetter and Ball Return installation. The power supply to the Ball Lift (bowlers end) & the Foul Detector is also included in the Switch® Pinsetter control box.
However, it is the responsibility of the customer to provide 2 X 50mm diameter plastic pipes, for under lane cabling and wiring for each pair of lanes (scoring, signal and ball return power cables). The pipes will be approximately 20 metres long, and be placed one on each side of the ball track. The pipes will be installed by the Switch® technicians during installation (effectively 1x20 metres pipe per lane) .
The Switch® Pinsetter Control Box is fitted with the following safety features :
-- Overload Protection - Each pinsetter has its own circuit breaker incorporated.
-- Residual Current Device - (Earth Leakage protection). Each pinsetter circuit breaker is controlled by an RCD to ensure that the risk of electric shock is kept to a minimum.
-- Minimum Voltage Monitor - Since 3-Phase motors are used in the Pinsetter, a special circuit has been provided to protect against the damage that could be caused, if for any reason there is an unacceptable imbalance between the 3 phases, an imbalance occurs or a phase is lost completely, the power is automatically disconnected.
All protection against potential danger overload, earth leakage, and unacceptable phase imbalance, is included in the Switch® Pinsetter control box, reducing the cost of the electrical installation, since these features do not have to be provided in the Main Distribution Panel for the Pinsetters. A “General Circuit Breaker” or Isolator for each group of 6 to 8 lanes is sufficient. One 5-core (5 x 4mm2- 3 phase + neutral + ground) is all that is required per pair of lanes. The cable should be installed above the Pinsetters, at approximately 3 metres behind the Curtain Wall, above the Pinwheels.
