NO OUTP Selects SINGLE or THREE phase mode of operation. In SINGLE
phase mode, all current is delivered to the ø1 and COM terminals of
the OUTPUT terminal block.
Note that even in SINGLE phase mode, a voltage is present at ø2
and ø3 terminals. Connect only a single phase load when operating
in single phase mode.
ST PHASE Selects the start phase angle for output changes made to either
voltage or frequency. This allows changing the output at a specific
phase angle. The Output on/off key also uses this phase angle
setting to program the output voltage up to the set level after the
output relay is closed. The default value for this field is RAND. To set
the start phase angle, set the cursor to the ST PHASE field and use
either shuttle knob to adjust between ± 360°. To set to RAND, use
the BACK key.
