Pendant Control Stations
Pendant control stations are devices used in industrial settings to control equipment, machinery, and processes. They typically consists of push buttons and switches mounted on a handheld pendant that hangs from a stationary or mobile support. The pendant control station allows the operator to remotely control the machinery, such as a hoist, crane, winches, and carts.
The control station usually has a two speed selection, allowing the operator to control the equipment's movement and speed. The pendant may have emergency stop buttons to provide safety protection in case of any accidents.
The pendant control station is typically housed in an enclosure for protection against environmental conditions and physical damage. The enclosure may have conduit holes for wiring and accessories such as contacts and operator switches. These pendant control stations are commonly used in industrial applications, including factories, warehouses, and construction sites, to control equipment and machinery with high precision and safety.
FAQs
What model of pendant control stations is best for systems that utilize hoists and cranes?
Schneider Electric has several models of pendant control stations available that are suitable for systems that utilize hoists and cranes. The best model will depend on the specific needs and requirements of the system.
Maintaining NEMA 4 Rating When Making Enclosure Penetrations
Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure.
This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure.
There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure.
If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
