Circutor CVM-C11 - 5�1�3�- Detection of Incorrect Direction of Rotation; Profile

5.1.3.- DETECTION OF INCORRECT DIRECTION OF ROTATION
The device has a system for detecting the incorrect direction of rotation of the voltages. In other words,
if each of the voltages has been correctly connected to the appropriate terminal, L1 to terminal UL1, L2
to terminal UL2 and L3 to terminal UL3.
If there is an error in the direction of rotation, the icons L1, L2 and L3 flash on the display.
The device has a RS-485 communications parameter, which indicates whether an incorrect direction of
rotation has been detected (“8.3.7. DETECTION OF INCORRECT DIRECTION OF ROTATION.”)


The phase angle between UL1 and UL2 is < 110º or > 130º.
The phase angle between UL2 and UL3 is < 110º or > 130º.
Note: The phase angle is 120º when the voltages are balanced.

PROFILE
This profile is identified with the symbol at the top of the screen.
The installation's consumed and generated energy are displayed on the e
3
profile of the device.
The installation status is also displayed:
Installation is consuming energy.
Installation is generating energy.
A long keystroke, ≥ 3 sec, of key will display the generation values. The generation values are
identified with the negative sign on the screen, which appears in front of each parameter.
A long keystroke, ≥ 3 sec, of key will display the consumption values.
Use keys and to browse the different screens.
