5�1�5�- Detection Of Incorrect Connection And Incorrect Direction Of Rotation 4 - Circutor CVM-E3-MINI-ITF Instruction Manual

CVM-E3-MINI
20 V is required to measure the voltage harmonics and of at least 200 mA to measure the cur-
rent harmonics. If the levels are lower, the unit will not calculate them and will display a value
of 0.
The harmonics display screens can be displayed by pressing the key shown after the last
profile screen.
Harmonics are represented as shown in . The figure shows the 15th voltage harmonic
Figure 28
(H15).

The key jumps to the next harmonics screen.
Press the key to jump from the voltage harmonics to the current harmonics, and from the
current harmonics to the home screen of the instantaneous values.
5�1�5�- DETECTION OF INCORRECT CONNECTION AND INCORRECT DIRECTION OF RO-
TATION
 Incorrect connection or disconnection
The device has a system for detecting the incorrect connection or disconnection of the voltage
lines. If this error occurs, the device displays 0 on the lines with a voltage value of less than 50%
of the line with the highest voltage value.
 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 10, L2 to terminal 11 and L3 to terminal 12.
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 ("
7.3.6. DETECTION OF INCORRECT DIRECTION OF
")
ROTATION
Note: The detection of the direction of rotation is only enabled for measurement systems:
Three-phase network measurement (4-3Ph, 3-3Ph y 3-ArOn) and two-phase network meas-
urement with 3-wire connection (3-2Ph).
