4.7.3 Interval Energy Recorder (IER)
The PMC-592 provides an IER which is capable of recording the following parameters.
Mains-I kWh/kvarh Import/Export and kVAh
Mains-I T1/T2 kWh/kvarh Import/Export and kVAh since Firmware V1.00.10
Mains-II kWh/kvarh Import/Export and kVAh
Mains-II T1/T2 kWh/kvarh Import/Export and kVAh since Firmware V1.00.10
1-Ø SM1 to SM84 kWh/kvarh Import and kVAh
2-Ø SM1 to SM42 kWh/kvarh Import and kVAh
3-Ø SM1 to SM28 kWh/kvarh Import and kVAh
VM1 to VM10 kWh/kvarh Import and kVAh
VM1 to VM10 T1/T2 kWh/kvarh and kVAh since Firmware V1.00.10
The programming of the IER is supported over communications or the Web Interface. The IER provides
the following setup parameters:

4.7.4 Waveform Recorder (WFR)
The PMC-592’s WFR has a log capacity of 16 entries organized in a FIFO basis, with the newest log
replacing the oldest one. The WFR Log is stored in non-volatile memory and will not suffer any loss in
the event of power failure. Each Waveform Recorder can simultaneously capture 3-phase Voltage and
Current signals at a maximum resolution of 64 samples per cycles. The WFR can be triggered manually
via communications or by the following alarms if they are enabled: Dip/Swell, Interruption, Mains
Voltage, Mains Current, Mains U/I Unbalance, Harmonics, Frequency,
Power and DI. WFR is triggered
by any alarm going active, and there is no need to do any configuration. The manual trigger command
