Safety Pilot Lights

Pilot devices provide control and condition monitoring of different types of processes, equipment and machinery in industrial and commercial applications. They are used for communication from a machine to an operator or from an operator to a machine. Pilot devices can be an audio or visual indicator, or an actuator that is used to control the flow of energy to a process. Visual indicators are: pilot lights, signal towers, strobes and beacons. Audio indictors are: buzzers and sounder horns. Actuators are: push buttons, selector switches, toggle switches and potentiometers.

Pilot lights are devices that provide visual information about the operating status of a circuit. They are normally used for on/off indication, alarm signaling and changing conditions. Pilot lights come in a variety of designs. Indicator pilot lights use LEDs or incandescent lamps as indicating lights in control panels and automated instruments. Relampable pilot lights feature a lens that can be replaced from the front panel of the lighted device once it stops functioning. Non-relampable pilot lights are designed with a fixed lens. Pilot lights include a colored lens such as, green, red, amber, white or clear. The colored lens represents the condition of the connected equipment or machine. A green pilot light normally indicates that the system is deenergized or off. A red pilot light normally indicates that a system is energized or on.
