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 BELOW thevoltageatwhichthechargingsystemfinishescharging.

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 Ah), will not work. Changing the Charged Current % to 6% would give a Charged Current of 12 amps, which would work.

WHYTHECHARGEEFFICIENCYFACTOR(CEF)ISIMPORTANT: 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 amp hours to store 9.0 Ah 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 amp hours. If so, set up appropriate Charged Parameters or

resynchronize periodically.
