3.5 Communication
There are two types of communication methods, RS232 and RS-485 supported in the SE inverters that may be communicated to the external
computer or terminal with RS-232 and/or RS-485 equipped. There is only one type of the communication can be used at a time. User shall
open the front lid to do the selection for the communication function. Figure 2.3.3.1 shows the selection of the communication type by select
the dipswitch in correspondent position on the control board. User should affirm that the dipswitch positions before using the communication
function.
3.6 Explanations of Error Messages
In the event of a fault, the inverter will stop feeding the AC voltage to the mains utility and display the error message on the LCD. Qualified
service personnel shall do the analysis, measurement, and debug if needed according to the error message in order to resume normal
conditions. It is recommended to screen out the fault condition(s) by referring to the table below and then remove the fault condition(s) to put
the inverter return to normal condition and continue to feed AC voltage to the utility steadily. Please contact Siliken Electronics if the same
error message is persistent.
