Installation and adjustment
        Mechanical interlock debug: conversion switch body should be carried out before installing the mechanical interlock debugging. A circuit breaker in the closing state, pulled the handle of another circuit breaker, with normal operating power, try to make the closing should be subject to the limitations of mechanical interlock and can not switch on the two circuit breakers alternate test The mechanical interlock shall be stable and reliable.
        Ontology of the transfer switch installation: selection of a suitable cross-section depending on the size of the rated current changeover switch body fixed wire to the input of the circuit breaker, the output terminal is connected. Special Note: The phase sequence of the input terminals of the two circuit breakers must be consistent, four-pole circuit breaker without additional zero line, but received for the three-pole circuit breaker is the zero line of the N terminal of the changeover switch.
        Will automatically split the installation of the automatic controller: with two support pieces controller fixed on the opening panel.
        The dedicated controller plug is plugged into a dedicated outlet to transfer switch seated and tighten firmly.
        Check the electrical contact parts are reliable and pressed, the fuse is intact.
        To pressure test, you should unplug the controller connector plug, otherwise the controller breakdown pressure test connector should be inserted firmly tight twist.
        The work of the whole power, if the voltage of the common power supply and standby power are within the normal range, the LCD panel indicator lights up when the common power supply and backup power supply undervoltage and phase failure, phase undervoltage indication "flash" , check the reason.
        Press the "Manual" button, select the common power supply and standby power, press the "automatic" button, then use the power at that time to enter the state of the automatic control; "breaking" key is pressed, all part of breaking the two-way power load.

Failure Analysis and Troubleshooting
        Unresponsive after boot, press the key in the control mode of the controller, the motor operating mechanism does not work, please check your circuit breaker power wiring and dedicated cable connection, three-phase power and neutral wire must be connected properly, the cable connection shall be seated twist prison.
        Power voltage of each phase were normal, but the panel display for under voltage, check the circuit breaker power supply is connected, the phase phenomenon.
        The controller is powered electricity, electric operating mechanism does not work, check the fuse conversion devices on whether current is too large due to electric operating mechanism and blown after replacement of the fuse tube and try again.
        Often blown fuse, check the electric operating mechanism is stuck, try the appropriate adjustments.
        After the above debug line connected to the whole power, working system that can be put into use, and control of the controller mode is set to "Automatic", "commonly used" complex "state, then the user needs to select working status, press the corresponding key.
