3.4.7
Voltage Down and Voltage Up Pushbuttons (12V and 24V sections):
These momentary push button switches will increment and decrement the output voltage of the
charger. Steps are approximately 50mV for the 12 volt output and 100mV for the 24 volt output. If
the unit is in EQUALIZE mode and either of these buttons are pressed then the unit will immediate-
ly revert to FLOAT mode. The voltage setting can not be increased while the unit is in CURRENT
LIMIT mode.
3.4.8
Over Voltage Protection Indicator (12V and 24V sections):
Red LED marked OVP. This LED is on whenever the unit has turned off due to an OVER VOLT-
AGE condition of the output. This LED will always indicate the true condition of the OVP system re-
gardless of a low voltage disconnect unlike the OVP relay.
3.4.9
Low Voltage Disconnect Indicator (12V and 24V sections):
Red LED marked LVD. This LED is on whenever the charger has disconnected the battery from the
load due to a low battery voltage.
3.4.10
Charger Fail Indicator (12V and 24V sections):
Red LED marked FAIL. This LED is on whenever the charger is unable to source power. Possible
fail conditions are AC fail, on battery mode, V
OUT
< 9 V, fuse fail, unable to source current into the
battery.
3.4.11
On Battery Indicator (12V and 24V sections):
Amber LED marked On Battery. This LED is on whenever the battery is connected to the load.
3.4.12
Test Points (12V and 24V sections):
Test points for 0.080” test probes. The test points indicate the charger output voltage inside the
charger output fuse(s). A 4.99 kohm resistor is in series with both the + and - test points to provide
short circuit protection.
3.4.13
Output Current Indicators (12V and 24V sections):
4 Green LEDs. These LEDs indicate the current flowing from the charger to the battery. Each LED
represents approximately 25% of full load. They do not indicate the amount of current following from
the battery to the load during a transfer. A flashing LED indicates current limit mode.
