radio remote control

Description

Introduction The Wecan series are highly durable, reliable and safe industrial radio remote control systems. The versatile features of the Wecan series permit their use in many different remote control applications. The systems can be used to control factory cranes, mononrail systems, multiple hoists, trolleys, minning equipment, building construction equipment, automatical control systems, and many others. The system incorprates numerous safety circuits that gurranty maximum secuiry and ensure the system is resistant to outside interference. The major features of Wecan series are as follow. The systems uses advanced microprocessors with highly evoloved software that has redundant errow checking and correcting capabilities to ensure **0% errow free transmission, decoding and control of all output relays. This highly evloved software includes CRC (Cryclical Redundancy Check Code) and Hamming codes (Errow Recovery) programming. To insure maximum operating safety, the Wecan series incorperates numerous safety features. Some of these built in safety features include transmitter pushbutton self-diagnosing, transmitter low-voltage detection and warnings, receiver self-diagnosing, MAIN deactivation during transmitter low-voltage and when the transmitter is in sleep mode. The transmitter encode and receiver decoder both utilize advanced microprocessor control. The availability of *2,**8 sets unique ID codes will ensure that only commands from the matching control transmitter can be carried out without any interfernece from other radio systems. For added saftey, the system also incorporates special type of safety MAIN contact relay or relays. If the safety MAIN relay becomes defective (fails to open or close during operation), it will signal the system to shut down immediately to avoid the possiblity of any accidents occuring.   *0 sets of user-adjustable receiveing RF channels plus special designd removable transmitting RF board for easy channel replacement and service maintenance.   **0% waterproofed transmitter and receiver enclosures, including the battery compartment.   The Wecan series radio remote control systems consist of water-resistant IP**6 transmitter and IP**5/IP**6 receivers. All receivers are equiped with a *-foot pre-wired output cable (Wecan ). The transmitter casings are molded using industrial strength composite materials which are impervious to dust, water, oil, acids, alkaline, heat and sunlight as well as being resistant to deformation due to long term use in harsh environments. The pushbuttons are also constructed from industrial strength composite materials with minimum of up to one million press cycles. For battery power savings, the transmiiter is designed and manufactured with a special ultra-efficiency power-savings circuit that requires only two”AA”size alkaline batteries for more than **0 hours of continous operation.               Safety Instruction The Wecan series are relatively simple to use, however, it is very important to oberserve the proper safety, productivity and efficiency in the workplace.   The following procedures should be strictly followed: 1.      Check the transmitter casing and pushbuttons daily. Should any damage that inhibit the proper operation of the tramsitter be found the unit should be immediately removed from service. 2.      The transmitter voltage should be checked on a daily basis. If the voltage is low (red status light blinking or completely off), the two “A” alkaline batteries should be replaced. 3.      The red emergency stop buttons (EMS) should be checked at the beginning of each shift to ensure it is in proper working order and the “stop” command is being received by receiver. 4.      In the event of an emergency press down the EMS button will immediately deactivates the receiver MAIN relay. Then turned the power “off” from the main power source to the crane or equipment. 5.      The transmitter power switch should be turned off after each use and should be never be left in the “power on” state when the unit is unattended. 6.      Don`t use the same RF channel and ID code as any other system in use at the same facility or wintin **0 feet distance. 7.      Ensure the wrist strap (Wecan series) or the waist belt (Wecan) is worn at all time during operaton to avoid accidental damamge to the transmitter. 8.      Never operate a crane or equipment with two transmitter at the same RF channel and ID code.   Caution! Improper storage of your Spare Transmitter is a Safety Hazard! During the initial installation of your remote control system the spare (second) transmitter should be tested to confirm that it is functioning properly and then the batteries must be removed and transmitter stored in a secured place. Faliure to follow this safety procedure can result in the inadvertent operation of your crane or hoist by unauthorized personnel resulting in serious injury or death!
