3.5 Troubleshooting
PURPOSE:
Start
Is
the FAULT
(110%) LED ON
or FLASHING?
YES
Simultaneously press
the % Load and %
Batt buttons for 1
second.
The LEDs now show
a fault code which is
read out on Figure
3.1. Their definitions
are listed in Figure
3.2.
After fixing the fault,
pushing the test
button resets the
UPS, clearing the
fault from the panel.
If the problem is fixed,
the code is cleared
from the panel. If not,
the fault code reap-
pears (Figure 3.3).
