POSSIBLE CAUSE
There is no voltage at the
•
DC input terminals.
There is no voltage at
•
the 12V power outlet in
the vehicle (when using
detachable cable set with
Cigar Plug)
Polarity of the DC input
voltage has been reversed
that has blown the exter-
nal / internal DC side fuses
(Note: Reverse polarity
may cause permanent
damage).
AC Load is exceeding
•
166% Surge Overload or
110% to 115% continu-
ous overload
Low DC input voltage
•
when supplying high AC
loads approaching 110%
to 115% continuous
overload.
Low DC input Voltage
•
Alarm
DC input voltage is
•
10.5V or lower but 10V
or higher for PST-300-12
DC input voltage is
•
21V or lower but 20V or
higher for PST-300-24
Shut-down due to low
DC input voltage - 10V or
lower for PST-300-12 or,
20V or lower for
PST-300-24.
REMEDY
Check the continuity of the battery
input circuit.
Check that the internal / external battery fuse /
vehicle fuse for 12V power outlet is intact.
Replace if blown. When powered from 12V
power outlet in the vehicle, ensure that the
Wattage of the AC load is less than 10 times
the Amp rating of the vehicle fuse being used
for protecting the 12V outlet.
Check that all connections in the battery input
circuit are tight.
Check external and internal fuses. Replace
fuses. If unit does not work, call Technical Sup-
port for repair.
Check that the battery is fully charged. Re-
charge, if low.
Check that the battery cables are thick enough
to carry the required current over the required
length. Use thicker cables, if required.
Tighten connections of battery input circuit.
Reduce load.
Check that the battery is fully charged. Re-
charge, if low.
Check that the battery cables are thick enough
to carry the required current over the required
length. Use thicker cables, if required.
Tighten connections of the battery input circuit.
Check that the battery is fully charged. Re-
charge, if low.
