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.

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
