2 11.. IINNTTRROODDUUCCTTIIOONN The Twister 2X is a highly sophisticated industrial radio control system. The versatile features of the Twister 2X permits a wide range of industrial applications. The Twister 2X industrial radio control system can be used to control all types of cranes, building construction equipment, automatic control systems, mining equipment, and many others. The Twister 2X incorporates numerous safety circuits that guaranty maximum security and ensure the system is resistant to other radio interference. The major features of the Twister 2X industrial radio control system is as follow: * Highly evolved software that have redundant error checking and correcting capabilities to ensure 100% error-free transmission, decoding, and control of output relays. These software designs include CRC (Cyclical Redundancy Check Code) and Hamming Codes (Error Recovery). * The encoding system utilizes an advanced microprocessor for 100% error -free data transmission. The availability of 65,536 sets of unique security ID codes will ensure that only commands from the matching control transmitter can be carried out without any interference from other radio systems. * The decoding system utilizes dual advanced microprocessors, which ensures 100% error-free calculation, bit checking, and correction of incoming transmitted data. * The system also utilizes an additional central microprocessor for data comparison and cross checking between the two decoding microprocessors to ensure 100% error-free decoding and control of all output relays. When faults are detected via this central microprocessor, for maximum safety, the entire system will be shutdown within 0.50 second to avoid any undesired crane movements. * The system utilizes PLL synthesized RF for means of data transmission. It allows the user to select from a wide range of frequency channels best suited for the environment. The frequency channel is selected via a dip-switch in the transmitter unit and LCD control panel in the receiver box. The receiver system also has the ability to auto scan from a wide range of frequency channels. The receiver system will search and locked on to the intended matching transmitter unit. * Optional dual advanced receiving system for optimum receiving capability. * The Twister 2X systems are equipped with numerous self-diagnosing features. These include transmitter low voltage detection  warning  system automatic shutdown, faulty pushbutton and joystick contact switches detection, faulty MAIN contact relay detection, faulty relay boards detection, faulty EEPROM detection, faulty PLL synthesizes RE unit detection, and incorrect security ID code detection.
3 22.. SSAAFFEETTYY IINNSSTTRRUUCCTTIIOONNSS The Twister 2X system is relatively simple to use. However, it is very important to observe the proper safety procedures during ope ration. When use properly the Twister 2X systems will enhance productivity and efficiency in the workplace. The following instructions should be strictly followed: 1. Make a daily check of the transmitter casing, joysticks, and pushbuttons. Should it appear that anything could inhibit the proper operation of the transmitter unit, it should be immediately removed from service. 2. The transmitter voltage should be checked on a daily basis. If the voltage is low, the battery pack should be recharged or replaced. 3. The emergency stop pushbutton (EMS) should be checked at the beginning of each shift to ensure they are in the proper working order. 4. In the event of an emergency, activate the emergency stop pushbutton immediately. Then turned the power “off” from the main power source of the equipment. 5. The power switch should be turned “off” after use and should never left the power “on” when the unit is unattended. 6. Do not use the same RF channel and ID code as any other unit in use at the same facility (within 300-meter range / 900 feet). 7. Ensure the waist belt is worn at all time during operation to avoid accidental dropping. 8. Never operate a crane or equipment with two (2) transmitter units at the same time with same RF channel and ID code. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operations. Changes or Modifications not expressly approved by the party responsible for compliance could void the users’ authority to operate the device.
4 33.. SSYYSSTTEEMM FFUUNNCCTTIIOONNSS TTrraannssmmiitttteerr JJooyyssttiicckk Each transmitter unit is equipped with up to two (2) joysticks with single or double axis per joystick.

Make sure that the red emergency stop button (EMS) is in its elevated position. 5. To activate the receiver MAIN, press and hold the “START” pushbutton located on the right side of the transmitter box for 2.0 seconds. 6. After system start up, if the operator did not give any command by pressing any pushbuttons or moving the joysticks to a non-neutral position, the transmitter unit will go into sleep mode with receiver MAIN contact relays temporarily deactivated. To resume operation, just press any pushbutton or move the joysticks again to re-activate the system. 7. After 1 hours of system non-usage, the entire system will be deactivated. 8. If the frequency channel of the transmitter unit is changed via a dip-switch inside the transmitter box (refer to page 13), you must then also change the frequency channel in the receiver box (refer to page 15~16). If the receiver unit is equipped with an auto-scanning feature, after changing the frequency channel of the transmitter unit, you must then press START button for up to 20 seconds after transmitter unit power “on” in order for the auto-scanning receiver to identify the newly selected channel. 99..22 TTrraannssmmiitttteerr SSyysstteemm SSttaattuuss DDiissppllaayyss (Fig. 17) 1.

To find out which contact point is defected or jammed, activate each pushbutton and joystick by pressing and moving each pushbutton and joystick speed one step at a time. Activating a non-defected pushbutton or joystick contact will display a fast blinking red light on the status LED. This fast blinking red light is to show the operator that the contact point currently activating is not defected. On the other hand, if the defected or jammed contact point is activated, the status LED will remain constant red with out any flashes. The main purpose of function is to let the operator realize which contact point is not working properly.

At discharging mode, the green blinking light will now turned into a constant red light indicating that the battery pack is now being discharged. If you want to cancel the discharge, just press “DISCHARGE” button again. 4. When discharging is completed, it will automatically switch to the charging mode where the green blinking light will appear again. 5. The charging time for a battery pack is approximately 3~6 hours (600mA). 6. When charging is completed, a constant green light will appear to indicate that the battery pack is fully charged. 7. When the battery pack is at 90% charged state, trickle charging will take over to ensure the longevity of the battery pack and as well as to ensure the battery pack is 100% charged. 8. When the battery pack’s temperature exceeds 50, the charger will go into protective mode and charging will be discontinued. 9. To prolong the life of the battery pack, it is recommended that the battery pack be fully discharged prior to every re-charging.
