SENS MicroGenius S2/S4 Technical Manual

7.2.2.1.
FLA
This setting is ideal for flooded lead-acid batteries used in engine starting applications. The
charging algorithm for flooded lead-acid batteries includes Float mode (see section
9.2
),
Dynamic Boost™ mode (see section
9.3
) and HELIX mode (see section
9.4
).
7.2.2.2.
AGM
The term, “AGM” in this manual and for the charger refers to AGM (absorbed glass mat) type
batteries that are employed in engine starting applications. For AGM type batteries
employed in non-engine starting applications please see “VRLA” below. The charging
algorithm for absorbed glass mat batteries includes Float mode (see section
9.2
) and
Dynamic Boost™ mode (see section
9.3
).
7.2.2.3.
NICD
This setting is appropriate when using nickel-cadmium batteries. The charging algorithm for
nickel-cadmium batteries includes Float mode (see section
9.2
) and Dynamic Boost™ mode
(see section
9.3
). Nickel-cadmium batteries are used in all applications.
7.2.2.4.
VRLA
The “VRLA” battery profile includes all valve regulated batteries, including AGM types, which
are employed in non-engine starting applications. For AGM batteries employed in engine
starting applications please see “AGM” above. The charging algorithm for valve-regulated
lead-acid batteries includes Float mode only (see section
9.2
).
7.2.2.5.
U12/U24
This setting is appropriate when charging ultracapacitors rather than batteries (see
section
9.5
). U12 indicates a 12V ultracapacitor and U24 indicates a 24V ultracapacitor.
WARNING:
ULTRACAPACITORS ACCEPT AND DISCHARGE CURRENT RAPIDLY. NEVER ATTEMPT TO
JUMP OR CONNECT A BATTERY TO AN ULTRACAPACITOR.
7.2.3.
Configuration Code
The Configuration Code indicates charging algorithm and alarm setpoints configured at the
factory. See sections 8 and 9 for further information.
7.3.
Apply AC Input Voltage
Verify the AC input is the correct value (90-265 VAC, 47-63 Hz) and apply AC to charger.
Depending on the state of charge of the batteries and the load on the DC bus, the charger may go into
current limit at this time, in which case the output voltage will be reduced as the charger operates in
constant current mode. Eventually as the battery is charged, the charging current demand should taper
to a value below the current limit setpoint of the charger, and the charger should revert to constant
voltage output. Chargers configured to use boost may be in boost for up to 24 hours depending on state
of charge of the batteries.
7.4.
Power Off
Power charger off as necessary by disconnecting both AC and DC in any order.

ALARMS, LEDS AND DISPLAY
8.1.
LED Indicators
The charger is equipped with two LEDs, one for AC status and one for DC status. See further alarm
definitions in section
8.4
. LEDs indicate an alarm on any output on chargers with multiple outputs. The
front panel LCD will indicate which output is in an alarm state.
