The front panel display for B Phase and C Phase units will display the leading
phase angle in degrees.
Typical 3 phase setup:
The A Phase at 0
°
, or reference phase. Switches 9 through 12 should be ON
for the A Phase Master CW-M Unit to set 0
°
.
The B Phase is set for a +240
°
or 240
°
leading phase angle (same as a -120
°
or
120
°
lagging phase angle) relative to A Phase at 0
°
Reference. This would
have Switch 9 OFF, Switch 10 OFF, Switch 11 OFF, and switch 12 ON.
The C Phase is set for a +120
°
or 120
°
leading phase angle (same as a -240
°
or
240
°
lagging phase angle) relative to A Phase at 0
°
Reference. This would
have Switch 9 ON, Switch 10 OFF, Switch 11 ON, and switch 12 OFF.
In this fashion, the phase rotation/sequence will be A-B-C-A-B-C etc.
