Samlex Europe PST-15S-12E Owner's Manual - Troubleshooting Guide
REMEDY
1 Check the continuity of the
battery input circuit.
2 Check that the battery fuse
is intact. Replace if blown
3 Check that all connections in
the battery input circuit are tight
Correct the polarity of the input
connections and replace the internal
fuse ( Note: Reverse polarity may
cause permanent damage) If the unit
does not work after replacing the
fuse, the unit has been permanently
damaged. Call Technical Support.
1 Check that the battery is fully
charged. Recharge, if low
2 Check that the battery cables
are thick enough to carry the required
current over the required length.
Use thicker cables, if required.
3 Tighten connections of the battery
input circuit
1 Check that the battery is fully
charged. Recharge, if low
2 Check that the battery cables are
thick enough to carry the required
current over the required length.
Use thicker cables, if required.
3Tighten connections of the
battery input circuit
1 Check that the voltage at the
DC input terminals is less than
16.5V for 12V version or 33V
for 24V version
2 Ensure that the maximum
charging voltage of the battery
charger / alternator / solar charge
controller is below 16.5V for 12V
version or 33V for 24 Vversion.
3 Ensure that an un-regulated solar
panel is not used to charge a battery.
Under cold ambient temperatures,
the output of the solar panel may
exceed 18V for a 12V battery system
or 36V for a 24V battery system.
Ensure that a charge controller is
used between the solar panel and
the battery
TROUBLESHOOTING GUIDE
SYMPTOM
On switching on, LED
(2) does not light.
Buzzer is off.
There is no AC voltage
Buzzer alarm is sounded
when load is switched on.
Voltage at DC input
terminals reads between
10 and 10.5Vfor 12 V
version or between 20
& 21V for 24V version
LED (2) is green.AC output
voltageis available.
Buzzer alarm is sounded
when load isswitched on.
Voltage at the DC input
terminals reads below
10V for 12Vversion or 20V
for 24V version. LED (2)
turns orange.
There is no AC output.
There is no AC output.
LED (2) turns orange.
Buzzer is on.
POSSIBLE CAUSE
There is no voltage at
the DC input terminals
Polarity of the input
voltage has been
reversed that has
blown the internal DC
side fuse
DC input voltage is
less than 10.5V for
12V version or less
than 21V for 24V
version.
.
Shut-down due to low
input DC voltage (Less
than 10V for 12V
version or 20V for
24V version.)
Shut-down due to high
input DC voltage
(>16.5V for 12V version
or 33V for 24V version).
