F07 - SET TEMPERATURE COEFFICIENT

DEFAULT = 0.5

RANGE = 0.1–1.5

STEP = 0.1

This factor compensates for capacity change with temperature. Typical value  0.5%

Capacity/°C. This coefficient must be supplied by the battery manufacturer. The default
value is typical for lead acid liquid or gelled batteries. Normally this value is not changed.

F08 - SET PEUKERT'S EXPONENT

DEFAULT = 1.25*

RANGE = 1.0–1.50

STEP = 0.01

Sets the exponent for Peukert’s equation. A setting of 1.0 defeats Peukert's

calculation. Properly setting Peukert's exponent ensures an accurate display of time
remaining. See page 26 for a discussion of Peukert's equation and typical values for various
batteries. *Default for liquid electrolyte batteries (F10 set to Type 1). When F10 is set to
gelled electrolyte batteries (F10 set to Type 2), a default exponent of 1.11 is used.

F09 - LOW BATTERY DISCHARGE FLOOR

DEFAULT = 100%

RANGE:  50%–100%

STEP: 5%

Your 

Link 20

 allows you to declare the discharge floor used for meter calculations.

An independent discharge floor may be selected for each battery bank. The display
floor will be applied to the battery bank selected (BAT 1 or BAT2) at time this func-
tion is invoked. As supplied by the factory, the discharge floor is 100% of amp-hour
capacity, corrected for high discharge rates. With the discharge floor to 100%, the

TIME 

remaining display essentially reports 

TIME

 to "dead battery." If you change

the discharge floor to 50%, you would essentially see the 

TIME

 "till the battery is

50% discharged." This is when charging should begin to conform to our 

"Mid

Capacity Rule.

"

CAUTIONS:

 If you discharge below the discharge floor, partially charge, but remain

below the discharge floor, the 

TIME

 remaining display will continue to read zero. The

TIME

 display will not show meaningful readings until you have recharged above the

discharge floor you have set. Also, remember that the light bar and 

TIME

 remaining

displays are run on 

rate compensated

 (Peukert equation corrected) amp hours.

 F10 - BATTERY TYPE

DEFAULT = 1

RANGE:

1 = WET (LIQUID) ELECTROLYTE

2 = GELLED ELECTROLYTE

This function declares your choice of liquid or gelled electrolyte batteries. Battery

Type is applied to both battery banks. We strongly recommend against designing
systems using both liquid and gel cells as their charging requirements are quite different.
The default value is Type #1, a liquid electrolyte lead acid battery. To select Type #2,
(gelled electrolyte lead acid batteries) set TYPE to 2. Changing the battery type sets an
approximately appropriate Peukert rate compensation exponent (1.25 for liquid cells and
1.11 for gel cells). When type 1 is selected, a Charged Voltage of 13.2 (or 26.4 V) is
selected, while Type 2 sets a default Charged Voltage of 13.5 (or 27 V). You may wish to
select a different Charged Voltage. See Temperature Compensation Table on page 17.
