With the exception of conveyors fitted with either an air-blast reject system or
Stop-On-Detect reject, a low-pressure air switch is fitted electrically in series with the starter
motor coil. This goes open-circuit if the air pressure drops below 40psi (2.8 bar).
The air supply is connected using 10mm O/D tubing to the 90° elbow. The elbow will be
located on the side of the air regulator unit or the air blast solenoid depending upon the
reject type fitted.
Checking guards
• Check that all guards are securely fastened in place. On some conveyors that are made to
special order, electrical interlocks may be fitted.
• Check that the infeed and outfeed of the conveyor are clear of obstructions.
Powering up the conveyor
• At the electrical services box, switch on the main isolator.
• Switch on the Control Unit.
• Switch on the compressed air supply to the conveyor.
