adjustment of the internally located time-out circuit adjustment pot may be recom-
mended. The procedure is as follows:
(Caution: Ensure a.c. input has been disconnected before proceeding)
1) Remove the two phillips head screws on the front panel (bottom right and just above
the output terminals), as well as the two phillips head screws on each side of the unit.
2) Carefully lift the main cover off of the charger base. It is not necessary to remove the
drip shield.
3) Locate the potentiometer labeled "TIMER ADJ" on the lower right hand side of the
front-facing charger function circuit board.
4) Using a small flat tip screwdriver, turn the potentiometer:
* clockwise to increase the amount of time the charger remains in the absorption
mode before timing out
* counterclockwise to decrease the amount of time.
The approximate ranges are illustrated below.
FIGURE 5: Adjusting the Time-out Circuit
Note: Once the time-out circuit has put the charger into float mode, the charger will
remain in this mode. Since the Phase Three Charger is well regulated, it is able to
deliver its full rated output current in this mode and battery discharge will not
occur (provided load current does not exceed charger rating and output wiring is
properly sized).
C) Gel-Cell — Flooded/AGM Switch
According to most battery manufacturers, the ideal charge regimen for gel-cell and
flooded (wet) lead-acid or AGM (Absorbed Glass Mat) batteries differs somewhat.
The gelled electrolyte in a sealed battery may be lost or damaged by high voltage and,
