There is no AC output. The
Green LED marked "POWER"
(2, FIG 6.1A) is lighted. Buzzer
is ON.
Shut-down due to high
input DC voltage – 16.5V
or higher for PST-300S-12E
and 33V or higher for PST-
300S-24E.
• Check that the voltage at the DC input ter-
minals is less than 16.5V for PST-300S-12E
and less than 33V for PST-300S-24E.
• Ensure that the maximum charging voltage
of the battery charger / alternator / solar
charge controller is below 16.5V for PST-
300S-12E and below 33V for PST-300S-24E.
• Ensure that an unregulated solar panel is not
used to charge a battery. Under cold ambient
temperatures, the output of the solar panels
may exceed 22V for 12V Panels or 42V for
24V Panels. Ensure that a charge controller is
used between the solar panel and the battery.
• Automatic Reset when voltage drops to
PST-300S-24E
AC output shuts down
completely. Red LED marked
"OVERLOAD" (3, Fig 6.1a)
is lighted. Buzzer is ON. The
Green LED marked "POWER"
(2, Fig 6.1a) is lighted.
Permanent shut-down of
the AC output due to con-
tinuous overload > 110%
to 115% for 2 to 2.5 sec
or due to short circuit on
the AC load circuit (AC
output voltage is 160VAC
or lower for 1 to 1.5 sec).
• Reduce the load / remove the short circuit
• The load is not suitable as it requires higher
power to operate. Use an inverter with
higher power rating.
• If the unit goes into permanent overload
again after resetting and removing the load
completely, the unit has become defective.
Call Technical support.
note:
The unit will be latched in this shut-
down condition and will require manual reset.
To reset, switch OFF the power ON/OFF switch
(1, Fig 6.1), wait for 3 minutes and then switch
ON again.
Before switching on again, remove the cause
of the shut-down.
There is no AC output. Buzzer
alarm is sounded. Red LED
marked "OVER TEMP" (4, Fig
6.1a) is lighted. The Green
LED marked "POWER" (2, Fig
6.1a) is lighted.
Shut-down due to over
temperature because of
fan failure or inadequate
cooling as a result of high
ambient temperature or
insufficient air exchange
Check that the fans are working. If not, the fan
control circuit may be defective. Call
Technical Support.
If the fans are working, check that the ventilation
slots on the suction side and the openings on the
discharge side of the fans are not obstructed.
If the fans are working and the openings
are not obstructed, check that enough cool
replacement air is available. Also check that the
ambient air temperature is less than 40ºC.
Reduce the load to reduce the heating effect.
After the cause of overheating is removed and
the unit cools down sufficiently, it will reset
automatically.
