F04 - DISPLAY AMP HOURS OR KILOWATT HOURS

DEFAULT OFF = Ah DISPLAY MODE

ON = kWh DISPLAY MODE

When this function is selected the Ah display shows kilowatt hours. Kilowatt hours are used internally by the Link 20 to determine if 100% of the energy consumed from a battery returned during charging. A recalculation of the CEF is not permitted unless this counter is greater than 0.00 kWh. This counter counts down during discharge and the kWh consumedaredisplayedasa negativenumber. Duringchargingitcountsbackupwith100% efficiency. CEF recalculation is prevented until the kWh counter is a positive number. This prevents premature CEF recalculation and Ah reset. Kilowatt hours is a very precise measurement of energy removed from or returned to your battery banks.

F05 - ALTERNATIVE ENERGY MODE

DEFAULT: OFF

ON: BATTERY/SOURCE MONITORING MODE

This function selects between the normal two-battery monitoring mode and the battery/source monitoring mode. When this mode is OFF, the meter works as a two-battery monitor as described elsewhere in this manual.

SOURCE MONITORING: When this mode is ON, the BAT 1 position works normally, showingenergyflowinginto(oroutof)Battery#1.TheBAT2voltandampsdisplays report the charging source voltage and current. The BAT 2 Ah display reports cumulative amp hours from one (or more) charging source(s). The BAT 2 Ah display will count up to 1999 and then roll over to 0 and continue to count up. This is the total number of amp hours supplied since the meter was powered up (or RESET). You may also use the kilowatt hours display (see previous function, F04). The BAT 2 Time display will read CCC. The BAT 2 CEF is set to 100% and is displayed as 100.

CHARGED PARAMETERS: Also, when this mode is ON, the time necessary to meet the Charged Parameters is reduced from five minutes to one minute. This is useful if your alternativeenergy installation uses solarpanelsandyouhave clouds periodicallyobscuring the arraycausing yourchargingto be intermittent. It's alsouseful ifyou'reusing an ON/OFF (high-low voltage set point window) controller. If you're using this type of controller, you may wish to increase Charged Current % to 3% or 4% of Battery Capacity.

F06 - MANUALLY SET CEF (Not Recommended)

DEFAULT OFF = AUTO RECALCULATION OF CEF

DISPLAY = A95

RANGE = 65–99 STEP = 1

Allows manual setup of CEF (Charge Efficiency Factor). Default display A95 indicates automatic CEF recalculation feature. Returning to A95 from a user declared CEF turnstheautomaticCEFfeaturebackon.Ifauser-setupCEFhasbeenselecteditwillappear as a Uxx in the DATA mode.
