22.18 Phase order
This function performs a wiring test by checking the phase sequence of the voltage channels. The
calculation is performed over 3 periods and every 10 periods of the input reference signal. If the phase
sequence is incorrect, then a symbol appears in the bottom banner of the display screen.

22.19 Hour meter
The monitors have three hour counters.
•
The first counter accumulates the time during which the power is on, that is to say the time during
which the auxiliary source is present. This counter is called the “Uptime” hour meter.
•
A second counter accumulates the time during which at least one measurement of the “averaged
over a second” phase voltages V
1
[1s], V
2
[1s] and V
3
[1s] is non-zero. This counter is called the
"Network Presence" hour meter.
•
A second counter accumulates the time during which at least one measurement of the “averaged
over a second” phase voltages V
1
[1s], V
2
[1s] and V
3
[1s] is non-zero. This counter is called the
"Charging" hour meter.
22.20 Average measurements
The averages are moving averages, being updated every tenth of the integration time. The integration
time is common to all quantities. This integration time is selected from the predefined values: 1, 2, 3, 4,
5, 6, 10, 12, 15, 20, 30 and 60 minutes.
All average values can be reset by writing a control word via remote or local communication. Resetting
consists of setting the value of the quantity to 0, with the exception of quantities of the type FP
x
and cos
(
ϕ
x
), which are reset to a value of 1.
