Product Name: Dual-Axis ControllerModel Number: QT7BPlace of Origin: China1. Applications: The master controller QT7B series is a rugged switching device according to the IEC standards for hoisting applications. The modular design enables the switching device to be used universallyA. It is suitable in AC 380V, 50Hz and DC 220V multi- direction control circuitB. The simulative controller, is suitable in DC for timing, commutating, and signals transfer2. Working condition:2.1 Permissible ambient temperature between -30°C to +60°C2.2 Height no more than 2,000 meters2.3 The relative humidity does not exceed 85%2.4 Degree of protection: IP543. Frame summarizeThe master controller is made up of control device and cam switch. The joystick ofthe control device has three types: round, squareness, squareness with button.It works by gear drive. Operate the joystick, via the gear transmission, make thecam of the switch drive, so the opening and close of the contact group will cometrue. We also can produce the master controller with spring return, interlockin zero position, also can install potentiometer, rotary transformer, self-angle-cleaningdevice, optoelectronic encoder, rotary encoder according to clients` request.For avoid mistakes (I.e. when impacted) we installed the device with interlock inzero position, the joystick is made of the upper and nether hemispheres, the joystickwill be off the zero position until the nether hemispheres was pushed up,then it can be operated. Disentwine the nether hemisphere and continue once thejoystick does not in the zero position.The max. operated angle of the joystick is + /- 42°, the max. actuating force is20N, switching sequence 6-0-6. One control device can control no more than 2 camswitches. The joystick can be operated "+" or "*" shaped when control 2 cam switches, the joystick can be operated "|" or"-" shaped when control 1 cam switch.There are no more than 12 contacts mounted in one cam switch normally, can mounted17 contacts specially.4. Technical data4.1 This crane controller is suitable for 8 hours/day working and discontiguous workingsystem, the operate frequency is 1,200 cycles/h, loading ingredient 40%.4.2 The degree of protection of shell is IP30.4.3 The mechanical life of the control unit is 3 million operating cycles under therated frequency, electrical life is 600 thousand in AC-15 application, 300 thousandin DC-13 application.5. Figure and installation dimension5.1 Look at picture 1 for the figure and installation dimension of control unit6. Installation, debugging, maintenance6.1 M12 installed bolts are used for fixing the controller6.2 According to the request of the electrical theory, should be control step bystep, look over if the contact close or open is according with the switching sequence,if not, please adjust it or replace the cam sheet6.3 Before controller electrified, please cut the master switch of the control screenoff, only operate the control loop to look over if the running programs ofthe controlled contacts are correct6.4 After the controller electrified, please check the running of the motor carefullyaccording to the catalog of the controller and control screen6.5 The controller should be examined and maintained frequently according to thefollowing requests:6.5.1 The joint of bolts should be fixed firmly6.5.2 The parts which are often rubbed should be kept lubricative
