Ac Input Fuse Protection; Battery Charger Display; Charger Setup: Lead Acid / Nicad; Forced Charging - Eaton FD120 Manual

EATON Diesel Plus
Diesel Engine Fire Pump Controller

3.1.4 AC Input Fuse Protection

The AC Supply is protected by a 6 amp fuse which will blow in
case of a breakdown of the charger. This fuse will not blow as a
result of overloading of the charger since the electronics will
shutdown the charger in this event before the fuse blows. If this
fuse is blown the charger must be replaced.

3.1.5 Battery Charger Display

The Diesel Plus chargers history will display Charging Voltage
and Amperage as well as error messages. The following will be
recorded according to the conditions that exist.
"NO BATTERY" is displayed if no battery is attached to the
charger.
"BATTERY ERROR" is displayed if a battery is connected to the
charger but the voltage is not within the minimum and
maximum thresholds for the selected battery type.
"ERROR, RECOVERING" is displayed if the maximum battery
charger output voltage (31.4V) has been exceeded.

3.1.6 Charger Setup: Lead Acid / NiCad

DIP switches on the charger can be used to select a number of
options including battery type and voltage as well as Forced
Charging. Options currently supported for the charger include
12 or 24 Volt Lead Acid and NiCad Batteries.

3.1.7 Forced Charging

There is provision for the battery chargers to provide a forced
charge to the batteries. The Forced Charge function will only
activate immediately after applying power to the charger with
DIP Switch 8 in the ON position and a battery connected.
When the charger is in the forced charge mode, it will attempt
to recover a battery by delivering 10 amps. If the battery does
not reach the minimum battery voltage (8 volts for a 12 volt
system; 16 volts for a 24 volt system) within 5 minutes, the
recovery attempt will terminate. Once the battery reaches it's
minimum battery voltage, the normal charge sequence will
commence.
Forced charging will only occur once per battery charger power
cycle.
