Toggle SW4 to move between ADJUST V23 and ADJUST V31. When the desired
parameter is shown on the display, toggle SW3 OFF then ON to enter selected menu.
When adjusting output voltage, make changes in small increments (5 V or less) to begin,
then let the menu time out to save the change. After “Programmed Successfully” is
shown on the display, return switches to the OFF position. Turn power to converter OFF,
re-install jumper wire between AUX1 and COM, then reapply power to converter and
measure voltages to verify change in calibration. Repeat this procedure, using smaller
increments as you get close, until desired output voltage is reached. When voltage
calibration has been completed, turn power to the PT OFF. Remove SW3 and SW4, re-
install the jumper wire connecting AUX1 and COM and re-apply power to converter.
Transformer Mode
WARNING! Risk of electric shock. De-energize the unit by disconnecting all incoming
sources of power, then wait 30 minutes for internal charges to dissipate before servicing
the equipment.
Transformer Mode will allow T3 to drop in voltage during heavy startups. This will require
wiring two ON/OFF switches to the converter. Standard light switches will work. See Figure
25, for wiring diagram.
To enable Transformer Mode, follow the steps below:
