In the CVM-A1x00-FLEX version, the neutral current is a calculated parameter, except in Single-Phase connec-
tion mode, where it is not supported.
(22)
The integrated variables are those that the device has as standard.
(23)
If in the device there is more than one module connected with the same type of inputs, the module with the
lowest number is the one with the lowest serial number.
(24)
When programming as an alarm a digital input programmed as logic state if:
- You program the maximum value = minimum value = 0 the output will show an alarm when the input has
a value of 1.
- You program the maximum value = minimum value = 1 the output will show an alarm when the input has
a value of 0.
Any other combination of values will cause erroneous behaviour of the alarm.
The pre-alarm value is not considered.

Codes valid only for programming the digital outputs of the transistor in impulse mode.

The quality variables cannot be configured in the expansion modules.
● When programming the pre-alarm value :
If the device exceeds the programmed pre-alarm value, the icon is activated on the
display, and the icon that indicates the alarm status changes colour: .
The value is programmed in %.
● When programming the minimum value below which the relay is activated:
The units and maximum and minimum values of the variables to program are shown in
Table 34
.
● When programming the maximum value above which the relay is activated:
The units and maximum and minimum values of the variables to program are shown in
Table 34
