Dongguan Changan key electronics factory was established in 2003, located in the factory of the world - Dongguan. Research and development, production, sales as one, with two brands: the the "STAROBOT robot and ELET Iraqi special forces. STAROBOT robot - a leading brand of automation equipment. Production of automatic soldering robot, screw fastening automation, automated dispensing, the automatic soldering tip and tip. ELET Iraqi special forces - the leader of the precise torque. Production of torque, torque tester, approved torque tester, hydraulic pulse torque tester, cap torque tester, automatic cap torque tester, the screw torque tester, shaft torque meter, lamp cap torque tester, split torque tester. , Fault phenomenon: the boot power light is off. Check the contents: the power is connected, the knife is closed, if it is a three-phase power supply phase loss. Remedy: connect the power, closed knife, failure phenomenon: the power indicator, the fan normal working indicator does not light. Check the contents: the start switch is in the start position Remedy: If the start switch in the start position, the machine does not work, the time you turn the start switch to the start position, fault phenomenon: normal light, the current fixed voltage regulator Check: Check the regulator current limiting and steady flow pressure limiting knob is adjusted to the minimum position Remedy: limiting the regulator, steady flow pressure limiting knob plating process requires spin to the appropriate location, fault phenomenon: the work which, sudden lack of current output, normal inspection of the work lights: Check the connection from the power output to the plating tank is disconnected Remedy: replace or re-cable is connected, failure phenomenon: the work which, all of a sudden there is no current output protection indicator flashes check the contents: 1, check the working environment temperature is too high, the fan is working properly Remedy: Troubleshooting the fan to improve ventilation check the contents: 2, to determine whether instantaneous overcurrent protection Remedy: re-boot the boot process, power can work check the contents: 3, the input voltage is normal, whether the lack of any over-voltage, under voltage, three-phase input Remedy: exclusion of distribution lines, power supply failure, reboot check the contents of the boot process: Check the power rectifier for shorts, Remedy: Replace the rectifier check the contents: 5, check the power devices for damage, the input rectifier module for damage Remedy: Replace the power devices of the same model and check the drive circuit for damage, have replaced, the replacement input plating rectifier module.
