The waveform selection is an option for the AC Power system. If the screen cannot be selected the option is not
enabled.
The WVF screen displays the type of waveform selected, sine wave (SNW) or square wave (SQW), for each of the
three outputs. To program a square wave, depress the SQW or any odd number key followed by any combination of
the A, B or C key, the PRG key and ENT key. If no phase key is depressed, the new waveform will be programmed for
all outputs.
To program phase A and C to square wave:
SQW A
C
PRG ENT
To select the sine wave waveform for any phase depress the SNW or any even number key followed by the key
sequence described above.

TO PROGRAM EXTERNAL SYNCHRONIZATION (SNC=1)
The SNC screen displays whether the external or internal SNC mode of operation has been selected. While viewing
this screen to select the external SNC mode, depress the EXT key followed by the PRG and ENT key:
Example:
EXT
PRG ENT
While operating in the EXT SNC mode, the FRQ screen will display the frequency of the External Sync signal. The
signal must be between 45 Hz and 550 Hz.
NOTE
When viewing the SNC, CLK or WVF screens, the MON or PRG keys must be
used to sequence to another screen. The MNU key can also be used to return to
the menu then followed by any screen selection.
To return to the internal SNC mode of operation, depress the INT key or any even numeric key followed by the PRG
and ENT key while viewing the SNC screen.
Example:
INT
PRG ENT
If the External Sync signal is not between 45 Hz and 550 Hz, the message will be 'EXT SYNC ERROR'.
In the EXT SNC mode the A value on the PHZ screen represents the angle of the A output leading the External Sync
input. If the zero degree point of the power source does not match the zero degree point of the External Sync input, the
POF screen may be used for calibration. Select the POF screen and enter a value for calibration.
