CHARGE ICON
In the event the battery charging (24V) mode is
selected (see set-up instructions) the CHARGE icon
is permanently illuminated in addition to the normal
POWER indicator icon. The charging mode is indicated in
two possible states:
– The CHARGE icon is illuminated intermittently
(pulsing amber). In this state the battery charging
output is in boost mode (stage 1) and operating
normally.
– The CHARGE icon is illuminated continuously (steady
amber). In this state the battery charging output is in
fl oat mode (stage 2) and operating normally.

OUTPUT LOAD INDICATOR
The OUTPUT LOAD indicator is used to display the value of
the load connected to the 24V output. The indicator consists
of fi ve LED bars from 25 to 125% (four green and one amber).
Push SET button momentarily to display the load in percentage
terms on the output. The percentage is based on the rating
of the SPCi. Continuous load should not exceed 100% of the
maximum rating of the SPCi specifi cation. In normal mode
only the green bars will be illuminated continuously (steady).
If the unit is overloaded the amber bar will be illuminated
continuously (steady) indicating 125% of load in addition to the
OUTPUT warning indicator. The display will indicate for 60
seconds before turning off automatically.
OUTPUT VOLTS INDICATOR
The OUTPUT VOLTS indicator is used to display the user
selected voltage of the SPCi (see set-up instructions). The
indicator consists of 5 LED bars from 24.0V to 28.0V in 1.0V
increments. The fi rst four bars are illuminated green and
the fi fth amber. The factory default setting is 26.0V which will
indicate for 10 seconds when powered up from the 24VDC
supply. If the output voltage setting has been changed the
new setting will be displayed each time the unit is powered
up. The display will indicate for 10 seconds before turning off
automatically.
