*P8
Max Allowed Charger Voltage 10.0-65.0V
Used only by SC-2030 charger See SC-2030 instructions
P9
Low Battery Audible Alarm Setpoint
0ff or 1-100 percent
OFF
When not OFF, audible alarm will sound and “battery
reminder” (bLO) will flash when “% full” is less than this
value, or if battery “volts” less than P13 setting.
P10
Assumed efficiency factor
60 to 100 percent
94
When meter calculates amp hours: Discharging always
decreases amp-hrs at 100% rate. When charging increases
amp hours at this specified percent rate. Also see section
6.2 step 4.
P11
Shunt type:
Sh.H = 500A/50mV shunt
Sh.L = 100A/100mV shunt
Sh.H
Shunt type for correct Amps and amp hour values. Also
see section 6.4, P11
P12
Automatic reset
ON
OFF
ON
When “ON”, Batt % full reset to 100, and Amp-hrs reset
to 0 when Charge criteria are met: P1, P2. Also see
section 6.2 Step 3, and section 6.4, P12.
P13
Battery low volts alarm:
10.0-65.0 volts
10.0
When volts is at or lower than this value, “b.LO” flashes
occasionally in display as “battery reminder.” Also
audible alarm occurs when P9 is not “OFF”. Also see
section 2.2.3 and section 6.4, P13. .
*P14
For SC-2030 Charger: sets maximum time
allowed to be in “absorb” before “float”
0.0 – 25.0 hours
0.0
For exact description, see charging profile graphs, near
page 14 of SC-2030 Solar Charge Controller User’s
Manual. . See section 6.2 step 4 and section 6.4, P14.
*P15
For SC-2030 charger: Max. voltage allowed
during." finish charge" stage.
10.0-65.0 volts
Used only by SC-2030 charger. See SC-2030
instructions
*P16
For SC-2030 charger: Float voltage
10.0-65.0 volts
Used only by SC-2030 charger See SC-2030 instructions
P17
Time before daily maximum measurement
will be recorded.
0-23 hours
(N/A)
For history data: H7, H8 and H9 (only): Adjust this to
number of hours after present time that daily measurement
should be recorded. (Usually to occur late at night). Also
see section 6.4, P17.
P18
Voltage calibrate. Set to correct batt voltage
(N/A)
This allows slight adjustment of battery voltage. Use
accurate digital voltmeter and adjust to that value. HOLD
RESET to INCREASE. Push RESET repeatedly to
DECREASE. Also see section 6.4, P18
P19
Program all factory values
Sets all values shown as “Factory values” in this table.
Hold RESET for about 4 seconds to accomplish. Also see
section 6.4, P19
*P20
Percent overcharge before float. 0-20 %
Used only by SC-2030 charger See SC-2030 instructions
*P21
Percent of P3 to which "amps" is limited
during "finish charge". 0-10%
Used only by SC-2030 charger See SC-2030 instructions
*P22
One button auto entry of eight most
important program data. Profiles: 1-31
Allows quick entry of all or most program data, especially
when used with SC-2030 charge controller
