The phase sequence table is used to control the phase sequence of the three -phase power supply.When the phase sequences are right, the relay of the phase sequence table is sucking; the phase sequence is wrong, and the relay of the phase sequence table will not be sucked.In the three -phase power supply, there are A phase, B phase, and C phase. If you connect to the motor according to the ABC phase -sequential power supply, the motor is positive, and the motor is connected to the motor according to the ACB phase -sequential power supply. The motor is reversed.In order to prevent the turning of the motor, add the phase sequence table to prevent the phase sequence of the power supply in the power supply, causing the motor to reverse.

How to use phase sequence tables
1 wiring: three table lines A (red, R), B (orchid, s), C (black, T) of the phase sequence tables correspondT) Three lines.2 Measurement: Press the measurement button in the upper left corner of the instrument, light up, that is, start measurement.When the measurement button is loosened, stop the measurement.3 Lack of phase indications: The three red light -emitting diode on the panel indicate the corresponding three -phase call.When the sources are lacking, the corresponding luminous pipe is not bright.4 Phase sequence indicator: When the three phase sequences of the measured source are correct, the green light corresponding to the positive phase sequence is on. When the three -phase sequence of the measured source is wrong, the red light corresponding to the counter -phase sequence is turned on, the bee soundsThe alarm sound was issued.Note 1: Positive sequences indicate UA0, UB0, UC0 (or UAB, UBC, UCA) behind 120 degrees in turn; reverse phase sequences indicate UA0, UB0, UC0 (or UAB, UBC, UCA) in turn 120 degrees.Note 2: To turn the counter -phase sequence into positive sequences, just exchange any two lines in the three lines of A, B, and C.The measurement time is not limited.
