In normal operating status the display shows the following parameters associated with the earth leak-
age protection, Table 8.
Table 8: Parameters visible by display.
Parameter Units
Instant current leakage mA / A
Programmed trip delay, td ms / s
Programmed sensitivity of trip, Id = I∆N mA / A
Contact status: Tripping relay
+ (contact 13-15 NO) / nothing (contact 13 - 15 NC)
+ (contact 14-15 NC) / nothing (contact 16 - 15 NO)
The RGU-10B allow the display and setting of all required parameters to complete the earth leakage
