How the operating hours counter works
Introduction
The AI Energy Meter 480VAC ST provides one operating hours counter for each phase,
which counts the operating hours of the load connected to a phase when there is current
greater than the configurable "Low limit for measuring current". The operating hours counter
for the entire module is calculated from the sum of the operating hours of the individual
phases. The operating hours counter has a value range from 0 to 3.4 x 10
stored retentively in the module and can be read via the data record 143 (energy counter
data record) and data record 150 (measured value for extended measuring and status
values).
Configuring
You configure the following operating hours counter settings in STEP 7:
● Activation of the gate for the operating hours counter
