6.3.4 UPS Maintenance Menus

Use the UPS Maintenance screens to conﬁgure and adjust the Alpha FXM to meet your operating needs.

To change parameters, either click the On/Off buttons or select an item from a drop down menu.

To execute the changes, click on the Update Conﬁguration button.

UPS Maintenance > Unit Conﬁguration

Sets the unit name, input, output and how often the Alpha FXM parameters update.

AC Output Shutdown

When this function is switched On, the Alpha FXM inverter is shut off. Neither line nor inverter power is sup-

plied to the load.

DC Output Shutdown

When this function is switched On, the LVD conﬁgured relay will be de-energized (Off).

Applies when ANY programmable dry contact is programmed to be the Low Voltage Disconnect indicator.

See "UPS Maintenance > Relay & Load Shed" on page 41. When the function is switched from On to Off, a 10

second delay occurs before the LVD congured relay is energized.

Automatic Frequency Detection

This setting is enabled by default and allows the unit to detect and automatically conﬁgure the AC input

frequency (50Hz or 60Hz).

In cases where the AC input frequency can be out of range for long periods, disabling the automatic conﬁgu-

ration prevents the unit from switching back and forth between 50Hz and 60Hz.

Power Quality or AVR

AVR (Automatic Voltage Regulation) switches on the buck and boost modes.

Quality switches off the buck and boost modes. The input voltage is the Alpha FXM output voltage.

AVR boost/line/buck thresholds (ﬁeld not available for 120Vac units)

For 230Vac units only, the AVR boost/buck thresholds can be conﬁgured (Figure 20). Select Reduced to

decrease the thresholds in order to be in Line mode when the AC input is between 195Vac and 239Vac.

Quality: line/inverter thresholds (ﬁeld not available for 120Vac units)

For 230Vac units only, the Quality thresholds can be conﬁgured (Figure 21). Select Increased to increase the

thresholds by 7Vac in order to be in Line mode when the AC input is between 219Vac and 260Vac.
