3. Plug 4159 into a 115 V outlet - max AC current draw is 15 Amps. For 230
Volt operation, internal jumper connection are changed (See VI for
diagram).
Do Not Connect Battery
4. Set Charge / Discharge switch (11) to Charge (center position).
5. Set Charge Current Adjust potentiometer (5) completely CCW to minimum.
6. Set Timer (2) to 180 Min (3 hrs). Time may be increased, even during
operation (Also decreased, if it is not at or below the led time displayed).
7. Set On/Off Switch (10) to On, (Meter LED’s, Digital Time and Ampere
hour Meter Displays Illuminate).
8. Set Charge / Discharge Switch (11) to the left “View Charge Voltage
Setting” position and hold it there (this is a momentary position and will
snap back to “Charge” when released). While holding it set Charge Voltage
Adjust potentiometer (6) to 28.5 Volts.
9. Release the Charge / Discharge Switch (11), the toggle will return to center
charge.
10. Switch On / Off Switch (10) to Off.
Connect Battery.
11. Switch On / Off Switch (10) to On. Voltmeter (3) will now read the open
circuit battery voltage.
12.
Adjust the Charge Current Adjust Knob (5) CW to maximum, or to the
current required, per NAVAIR 17-15 BAD-1. When set to maximum, the
Ammeter (17) reads charge current to a maximum of approximately 25
amps or to lesser amperes that the battery accepts due to its capacity/size,
state of charge and condition. The Ampere hour meter (16) records Amp-
Hours of charge into the battery.
13.
As time progresses charge voltage climbs to 28.5 volts. The Voltage holds
Constant at 28.5 volts, Current begins to lower (taper). This is a
Constant Potential Charge. When charge current tapers to a low level
(typically 1-3 amps for larger batteries (20-60 AH) or under 1 amp for
smaller, charge is complete. Usually 2-3 hours. Charge stops at end of
timing.
