Charged Parameters & CEF
If you change the Charged Parameters please use the following rules.
1) The Charged Voltage Parameter MUST BE AT LEAST 0.1V BE-
LOW the voltage at which the charging system finishes charging.
Example: If your charging system finishes the battery at 13.8 Volts, a
Charged Voltage Parameter of 14.0 Volts will not work. Lower the Charged
Voltage Parameter to 13.7 Volts or less.
2) The Charged Current % times declared Battery Capacity MUST be
GREATER than the minimum current at which the charging system
maintains the battery, or turns off.
If the Charged Current % times the Battery Capacity is less than the current
at which the charging system switches off, the Charged Current Parameter
cannot be met. For example, if the charging system shuts off when the
current is 10 Amps, using the factory default value of 4 Amps (2% of 200
AHrs), will not work. Changing the Charged Current % to 6% would give
a Charged Current of 12 Amps which would work.
WHY IS THE CEF IMPORTANT: The CEF determines the rate at which the
meter counts back up during charging to compensate for the inefficiency of the
charging process. The CEF has a factory default value of 90% . This means
that you must return 10.0 Ahrs to store 9.0 Ahr in the battery.
If you have a charging system that cannot satisfy the Charged Parameters, the
CEF will not be recalculated and the meter will use the default CEF of 90%. This
will work fine in most systems. You may notice an accumulation of negative
Ahrs. If so, set up appropriate Charged Parameters or resynchronize
periodically.
