General Information and Motor Features
All AMS motors are designed and engineered to meet the highest technical standards in the industry. They go
through stringent testing at AMS’ ISO 9001-2015 certified facilities and must meet or exceed 30,000 life cycles.
All AMS motors are equipped with mechanical limit adjustments rather than electronic ones to prevent accidental
loss or inadvertent change of limit positions due to power surges, noise, power outages or other electronic
interferences.
AMS motors do not require any maintenance or servicing over their lifespan.
AMS’ tubular motor 4280P is equipped with an internal safety spring-clutch that serves as a safety feature in case of
an unexpected breakage of a motor shaft; this safety feature would prevent the shade from unravelling.
Each motor is equipped with a metal planetary gearbox and metal gears that provide strength and longer durability
than gearboxes made with nylon gears.
A large number of help manuals is available on the AMS website under “Support”’ where you will find detailed and
illustrated help and tips on such issues as replacing shades, wiring diagrams, troubleshooting of electrical shades, etc.
