LE579WL3902 is a commonly used panel indicator, pilot light, designed for motor control applications. It is a four pole, two-conductor, three-position terminal block structure, providing a three-position switching capability for motor relay control applications. This particular block is rated for current carrying capacities up to 15 A and Volt-amperes up to 9 VAC/DC.

This panel indicator, pilot light, requires an external supply which supplies power through a voltage converter connected to the intended terminals. Typically, a DC voltage of either 9 volts or 5 volts is used depending on the model used. A 0.1uF polarized capacitor should be connected between pins 8 and 7 for the correct functioning of the device. The current carrying capacity depends on the impedance of the connected circuit and should be determined experimentally.

In motor control applications, this panel indicator, pilot light, is often used as a switch for activating the motor relays. When the switch is activated, the relay will start and the motor will begin to run. LE579WL3902 also contains a logically de-energized state, which can be used to turn off the motor after the switch is released. Furthermore, the device is capable of providing specific indications, when connected to indicators that have been properly installed.

In order to operate properly, LE579WL3902 must be mounted to a panel and wired, so that the switch contacts of the three-position terminal block are properly connected to the intended motor relay controllers. These connections must be correctly wired during installation to ensure that the application is operating correctly. Proper installation and connectivity lead to both improved reliability and better efficiency.

The terminals of LE579WL3902 must also be properly insulated for safety. To further security the panel indicator, pilot light can be fitted with several additional safety features such as a ground-fault circuit interrupter, dust cover or a dust-proof film.

LE579WL3902 is a common panel indicator, pilot light, with many different applications. With proper installation and wiring, the device is extremely reliable and can provide effective motor control for any application.
