Regulator Operation

Once the WS100 regulator is properly wired to the alternator and
configured for your battery type, the regulator is ready to begin charging
your batteries. Following a short delay, the regulator will begin to ramp
up charging voltage to a bulk target voltage that’s determined by your
charging profile selection.
Once the regulator reaches bulk target voltage, the regulator will continue
to hold at target until the field pulse width falls below its target level, and
the regulator will advance to the acceptance target voltage (typically two-
tenths of a volt below bulk target voltage). The regulator will continue
to charge at acceptance target voltage until the field pulse width drops
below minimum target, at which point, the regulator will advance to float
voltage.
While at target voltage for float, the regulator will monitor the field pulse
width. If the maximum float pulse width cannot maintain the target voltage
for float charging, the regulator will return to acceptance charging voltage.
During extended engine operation and under varying battery loads, the
voltage may cycle between charge modes multiple times.

During normal operation, the regulator will display a combination of green
lights in positions marked one through five, indicating the progress of the
charge program. A combination of lights, as described below will indicate
charging activity status. Codes are as follows:
1. #1 green light — Indicates regulator is turned on.
2. #1 & #2 green lights — Indicates regulator is in bulk charge mode.
3. #1 & #3 green lights — Indicates regulator is in absorption charge
mode.
4. #1 & #4 green lights — Indicates regulator is in float charge mode.
5. #5 green light — Indicates Dash Lamp mode is active. May be
active as a result of low system voltage, high system voltage, high
alternator temperature (>225°F) or high battery temperature (>125°F).
