Delay
This refers to the time in seconds that must occur before the UPS recognizes an alarm function. The
delay can be anywhere from 0 to 99.9 seconds in 0.1 second intervals. If an alarm is set to Latch, it
will only recognize the alarm and latch after the delay period.
Figure 71 Alarm / fault name screen
The Alarm / Fault Name Screen can be accessed from the Configuration Screen (Figure 40) by high-
lighting Alarm Mask and pressing SELECT.
When the Alarm / Fault Name Screen is displayed, the highlighted alarm will be flashing. (In the fig-
ure above, BATT. FUSE FAIL will be flashing.) The DESCRIPTION at the bottom of the screen
defines the letters L, D, F, and E. The DESCRIPTION scrolls from right to left, allowing the Operator
to see the entire list of features.

certain attributes by following these steps.

SELECT navigation button to bring up the Edit screen below.
b. To scroll up the list, highlight UP on the display screen and proceed as in a.
