Device Setup

Serial connection and Modbus addressing.

Step 1

Modbus Address

Baud Rate

Serial Log

Communication messages and status updates.

Meter Options

Line frequency, wiring scheme, and CT ratio (applied via ext.atm).

Line Frequency (Hz)

Wiring Scheme

CT primary (A)

CT secondary (mA)

N = primary / secondary_mA (software scale). Enter or leave the field to write. PGA writes the chip — change only with the input path. N = 2 · input = — % of 60 mA (indicative)

Advanced settings

Sum Mode (0=alg, 1=abs)

PGA (advanced)

L1 channel → meter phase

L2 channel → meter phase

L3 channel → meter phase

Phase mapping is written to ATM90E32 ChannelMap registers on apply.

Calibration (Phase A / B / C)

Press Enter in a field to send. Live refresh pauses while editing.

Alarms (L1, L2, L3, Totals)

Active below min and/or above max (empty side = unused). With Ack required, the LED/DI stays latched after the condition clears until Ack. Chip PQ bits are under Chip Events.

Relays (2)

Enable, invert, Modbus or Alarm Controlled relay follow.

Live Meter

Updated from ENM_Meter / ext.meter (~1 s).

Peaks & Quality

ATM90 peak registers (F1–F3 / F5–F7), neutral current, computed active-power THD (not THD+N).

Chip Events (ATM90)

Hardware PQ faults from ext.chipEv (same bitmasks as Modbus IR 101–104).

Energies

Chip counters from ENM_Sync / ext.energy (saved in flash).

Buttons (4)

Live state via io.btn.

User LEDs (4)

Source 5/6 = relay 1/2 logical state. Alarm/Warning/Event L1..Total = latched alarm state per channel.
