Type of Error
The BUILDING POWER in-
dicators on the system
control panel and trans-
former control panel are
not illuminated.
The in-
BUILDING POWER
dicators in the transformer
control panel or system
control panel are on, but
pressing the
SYSTEM ON
button does not power up
the system.
Once the SYSTEM ON but-
ton in the system control
panel has been pressed, it
lights up automatically,
however, no output power
is present.
As a result, the system on
indicator in the transformer
control panel does not light
up.
Partial or total failure of the
power output, even if the
green
BUILDING
indicators are illu-
POWER
minated.
Should the isolation transformer malfunction, only qualified personnel should be per-
mitted to perform troubleshooting.
Possible Cause
No mains power present at
the input line.
Due to overload, the mains
input fuse switch on the
transformer control panel
has tripped.
Internal isolation
transformer failure.
The
EMERGENCY STOP
switch is active (pushed
in).
Due to overload, the inter-
nal thermal fuse in the iso-
l a t i o n t r a n s f o r m e r h a s
tripped.
The earth leakage current
breaker has tripped, indi-
cating leakage current ex-
ceeding 30 mA.
Due to overload on one or
more output lines, one or
more circuit fuse switches
have tripped.
