c) The High temperature light indicates
the inverter has overheated. The unit will
automatically turn back on when it has
cooled to 40
o
C (104
o
F). Verify that the
inverter is not in a closed compartment and
that the fan is not blocked.
5.03 When the battery charger fails to
operate correctly check the inverter trouble
shooting procedure in 5.02, assure that the
remote trmperature probe is installed
correctly, then observe the front panel
lights:
a) The external power light should be lit, if
not, verify that the external power circuit is
providing 120 or 240 VAC, 60HZ power to
the unit. Check all external power wiring and
external circuit breakers or fuses.
b) The green Timer Complete light indi-
cates the unit’s battery charger was unable
to completely charge the battery(ies) during
the 12 hour charge cycle. One or more of
the following conditions can cause this
condition.
1) Verify that the two switch settings
("BATTERY TYPE" and "BATTERY BANK
SIZE") are correctly set.
2) The charger was unable to detect the
80% charge level point during the 12 hour
cycle due to a defective battery.
3) The battery’s voltage dropped below
25.2 volts while the charger was attempting
to detect the 80% charge level. A battery
with a shorted cell or incorrect acid density
can cause this condition.
4) More than 20 Amps of DC load current
was drawn directly from the batteries during
the charge cycle.
5) AC power loss (brown out) in the
external AC input that limited the amount of
AC power available to the battery charger.
5.04 A new charge cycle may correct the
Timer Complete condition if the cause seems
to be conditions 1, 4, or 5. The new charge
cycle can be started by disconnecting both
external AC inputs for 5 seconds then recon-
necting them.
5.05 Call Sensata for technical assistance
and/or a Return Authorization Number if the
above steps are completed and the inverter
or battery charger will not operate satisfacto-
rily.
