¾ SW1 Equalizing charge timer (Remarks: Do not operate this switch.
)
With the standard settings, when equalizing charge mode is set with the panel's CHARGE
switch, the device automatically returns to floating charge mode after 10 hours. Also, when
the equalizing charge current is less than 3 A, the device automatically returns to floating
charge mode.
¾ SW2 Floating/equalizing charge voltage switching
Used to switch the charging mode when adjusting the floating charge voltage and the
equalizing charge voltage for the battery connected.
¾ SW3 Over discharge prevention (Remarks: Do not operate this switch.
)
When enabled, the BATT breaker is tripped when the battery voltage is less than 19.5 V.
Note 1: Functions only during discharge.
Note 2: Does not operate for momentary (approx 0.1sec or less) voltage fluctuations
from surges when starting the device.
¾ SW4 BATT HI/LOW TEMP input control
When this switch is enabled and a battery temperature detection signal
*1
is connected to the
accessory terminal (described later) BATT HI TEMP or BATT LOW TEMP terminal, charging
voltage is output according to the input battery temperature (high or low).
*1. Output signal of the thermal lead switch attached to the battery.
¾ SW5 Prohibit equalizing charge
When enabled, the panel's CHARGE switch is disabled. Used to prohibit equalizing charge of
a lead sealed battery.
¾ SW6 Detect BATT connection (Remarks: Do not operate this switch.
)
When enabled, if the battery is connected in reverse or a battery is not connected, the
protection circuit trips the BATT breaker.
