Battery
SEL-351P Quick-Start Installation and User's Guide (Portuguese) 71
MODE = CHARGE - battery is charged
≥
90% (trickle charging)
HICHRG - battery is charged < 90% (high charging)
DISCHRG - battery is discharging
DISTST - battery load test in progress
NOBATT - battery is damaged or disconnected (it
cannot charge or discharge)
FAIL - battery monitor/charger failed or
communications with the battery monitor/
charger are temporarily interrupted
%CAP = 0 to 100 - battery charge level (independent of
temperature).
HRS_LFT = hh:mm – hours and minutes left to run on battery in
discharge mode before the SEL-351P puts itself to sleep
(dependent on setting “% Battery capacity for sleep
[0-100]”). Shows XX:XX if battery is charging.
5V_PSBC internal 5 V power supply level for battery
monitor/charger.
12V_AUX 12 V power output level – available via terminal block
positions 23 and 24 – controlled by two 12 V settings in
preceding
Battery-Related Settings subsection.
VBAT = voltage level of 24 V battery.
IBAT = current level (in mA) at which the 24 V battery is
charging or discharging (preceded by a minus sign for
discharging).
Battery Status via Serial Port
Execute the STATUS command, and have the same information
available via the preceding front-panel STATUS pushbutton.
Automatic Battery Load Test
The SEL-351P automatically load tests the 24 V battery about every 24
hours.
An internal 24-hour timer cumulatively times whenever the SEL-351P is
in the charge mode (120 Vac is powering the SEL-351P and charging the
battery). Even if the battery is fully charged, it is still trickle charged
and thus, the SEL-351P is still in the charge mode.
After the 24-hour timer times out (and the SEL-351P is still in the charge
mode), a 1 Amp load is automatically paralleled with the battery for 5
seconds. If battery voltage drops below 80% nominal (temperature-
compensated voltage level) during this load test, the BATERIA
PROBLEMA LED illuminates and stays illuminated until the next
Was It a Load Test Failure?
If the BATERIA PROBLEMA
LED is illuminated and MODE
displays neither NOBATT, nor
FAIL, then the battery failed the
latest load test. See the
following
Load Test
subsections.
