Chapter 1 System Description 9

Password protection for important operations

The users must input the correct password before they conduct “Maintenance” and “Settings” operations. The password has 3 levels: user, operator or administrator. The authorities of the 3 levels are the same while conducting “Maintenance”, but different in conducting “Settings”. The operator can see 3 more pages than the user, which are “resetting system”, “resetting password” and “modifying system type”. The administrator can see 2 more pages than the operator, which are “modifying password of all levels” and “controlling alarm sound volume”. In addition, the administrator can browse the rectifier parameter serial No., software version and the setting of internal switches. See the following table:
