PROTECTIONS AGAINST ABNORMAL CONDITIONS
6.1 LOW BATTERY ALARM:
In case the battery voltage drops below
21.4V, a buzzer alarm will be sounded. Green “Power” L.E.D. will remain on.
Output voltage will still be available.
6.2 LOW BATTERY SHUTDOWN:
In case the battery voltage further
drops to 20V or below, the inverter will shut down the output voltage.
Buzzer will be sounded and the green “Power” LED will be off.
6.3 INPUT OVERVOLTAGE SHUT-DOWN:
In case the input voltage
is 30V or higher, the output voltage will be shut down. ( CAUTION! This
condition may cause permanent damage.)
The green “Power” L.E.D. will be off and the buzzer will be on
.
6.4 OUTPUT OVER-LOAD OR SHORT:
If there is overload or short
in the output, the output voltage will be shut down. The green “Power”
L.E.D. will be off. The red “over-load” L.E.D. will be lit. Remove the
overload/short circuit condition. Switch off the D.C. power with the on/off
switch, and switch on again. (Unit will remain latched in shut down
condition. Input power is required to be switched off and on
again to reset the latch).
6.5 REVERSE POLARITY SHUT-DOWN:
In case the positive (+) or
negative(-) connections on the input side are reversed, the 20A fuses inside
the unit will blow. The LED green “Power” will be OFF. ( CAUTION! This
condition may cause permanent damage.)
6.6 OVER TEMPERATURE SHUT-DOWN:
In case the unit gets
overheated due to inadequate cooling, the output voltage will be shut-
down. The green “Power” L.E.D. will be off. The buzzer will be sounded and
the red “over-temp.” L.E.D. will be on. Switch off the load. Determine and
remove the cause of overheating. The unit will auto reset when it
cools down.
NOTE:
Check the Troubleshooting Guide for possible remedies
to prevent the above abnormal conditions.
