INTRODUCTION
The Alpha 500 series are highly reliable industrial remote control systems. The versatile
features of the Alpha 500 series permit its use in many different remote control applications.
They can be used to control cranes, hoists, trolleys, mining equipment, building construction
equipment, automatic control systems, and many others.
The Alpha 500 series radio control system incorporates numerous redundant safety circuits that
guaranty maximum security and ensure the system is resistant to outside interference. The
major features of the Alpha 500 series are as follow:
* The system uses advanced microprocessors which utilizes highly evolved software that
have redundant error checking and correcting capabilities to ensure 100 % error -free
transmission, decoding, and control of the output relays. These highly evolved software
include CRC (Cyclic Redundancy Check codes) and Hamming Codes.
* To insure maximum operating safety, the Alpha 500 series incorporate many safety features.
Some of these safety features include receiver self-diagnosing, transmitter pushbutton
self-diagnosing, transmitter low voltage detection/warning, transmitter/receiver auto
shutdown after 1 minute of transmitter low voltage warning, and receiver MAIN
deactivation during transmitter non-usage (programmable from 0~30 minutes).
* The encoder/decoder system utilizes advanced microprocessor. The availability of 32,768
sets of unique ID codes will ensure that only commands from the matching control
transmitter can be carried out without any interference from other radio systems. A special
programmable integrated circuit is used to insure the unit can not simultaneously command
conflicting movements.
* Full SMT design for system stability.
The Alpha 500 series radio control system consists of a transmitter handheld, a receiver unit, and
a six-foot (2-meter) output cable. The transmitter casing is molded using an industrial strength
composite material which is impervious to dust, water, oil, acids, alkaline, heat, sunlight, and as
well as being resistant to deformation due to long term use in harsh environments. The
pushbuttons are also constructed from industrial strength composite material with a minimum of
up to one million cycles. For power saving, the transmitter unit uses special high efficiency
power saving circuits that requires only two “AA” alkaline batteries (UM-3).
