4.3.12 Dip, Swell and Interruption Alarm
The PMC-592 with Firmware V1.00.05 or later supports Dip/Swell and Interruption Alarms according to
IEC 61000-4-30 with 1-cycle update instead of ½ -cycle as specified by the standard. The following table
illustrates the Dip/Swell and Interruption Alarm parameters and their respective default values.

Table 4-19 Dip/Swell Alarm Parameters
It should be noted that the
Dip/Swell/Interruption Alarm Limits
are calculated based on
Nominal
Voltage
, which is defined as the
a)
Nominal ULN Voltage (Modbus Register 6001)
in Firmware V1.00.09 or before
.
b)
Mains-I/II PT Secondary (ULL) (Modbus Registers 6043 and 6046, respectively)
in Firmware
V1.00.10 or later,
replacing
Nominal ULN Voltage in pervious Firmware versions
.
