Note
Assignment channel in diagnostics alarm ⇔ Phase
Channels are counted in the diagnostic messages starting from channel "0" and in the
AI Energy Meter 400VAC ST starting from phase "1".
Note the following assignment:
• Channel "0" ⇔ Phase "1"
• Channel "1" ⇔ Phase "2"
• Channel "2" ⇔ Phase "3"

2 Line voltage (measuring range) is monito-
H
red for tolerance. Violation leads to voltage
3
H
overflow/underflow
4 The measured current is monitored after
H
expiry of the "Tolerance time" for "Tole-
rance value overcurrent [0.1 A]". Excee-
ding this results in overflow current.
The maximum value of the secondary
current (12 A) has been exceeded.
7 Cumulative overflow in the calculated va-

rement. The message occurs when the
configured minimum current or voltage is
below 80 V.

Channel 0 applies to the entire module.
The module is currently not performing any
measurements.
A user calibration is being executed at the
channel.
