7, Rectifier System Maintenance

(1) Failure: yellow LED on rectifier module flickers, communication fails;

Maintenance solution: check the communication network to see whether the internet connection is loose, internet interface is damaged, or network wire is damaged.

(2) Failure: yellow LED on rectifier lights on;

Maintenance solution: check whether the fan is blocked, load current exceeds the max. value; AC voltage is too low, then the auto rate decrease starts; over temperature pre-alarm starts; remote shut-down is started on PC software.

(3) Failure: Red LED on rectifier lights on;

Maintenance solution: check whether the voltage is too high/too low and over/under voltage protection is on; fan is blocked; ambient temperature is too high; load is short circuit or not.

If above mentioned parts are ok but the red LED is still on, then there is problem on the module, please return it to factory for repairing.

(4) Failure: Yellow, red, green LEDs on rectifier are all off;

Maintenance solution: firstly check whether AC input is available or not, if not, then check the electrical circuit; if yes, the module is in malfunction, please return the module to factory for repairing.
