Output Voltage Forms; Audible Alert - Pacific 110ACX Operation Manual

SECTION 4 OPERATION

OUTPUT VOLTAGE FORMS

The ACX is a dual-range power source. The output voltage range is selected by the FORM
setting selected in the UPC controller. See the UPC Series Operation Manual for setup. The
standard output configurations are:
FORM 1: 0 – 150 Vac
FORM 2: 0 – 300 Vac
A recommended strategy for selecting the optimum output voltage form is to select the minimum
voltage range necessary to drive the load. That will provide the maximum available current and
allows the power source to operate more efficiently. This results in less heat being created within
the unit.

AUDIBLE ALERT

An audible alert within the ACX will sound to indicate any of several conditions:
1) When power is applied, it will "beep" 2X indicating normal start-up.
2) If the AutoStart option has been ordered, the unit will "beep" several times indicating
normal start-up and activation of the unit output. Power may be present at the output
terminals immediately, depending on the active program settings. See the Modification
insert if applicable to your unit for more information.
3) During operation a steady tone may be produced, indicating one of the following
operational limits has been exceeded:
•
•
•
Input AC voltage is too high or too low; not within the 90-264 Vac specification.
Input current has exceeded 25 Arms. This could occur at low input voltage and
high power output combination.
Output power demand exceeds the specified 120% overload condition.
