DOWN buttons will also advance through the
functions. Press ENTER.
Response:
The function will be executed and
continue to display the function number or the
display

the
programmable function.
(d) To change a programmable function (only
Functions 8-11, 13-15, 18-20, and 22-26 may be
programmed), press the UP and DOWN buttons
until the new value desired is displayed. Press
ENTER.
Response: The new value is stored in the charger's
memory and the function number is displayed. If
CLEAR is pressed, the new value is ignored and the
function number is displayed.
(e) To exit programming, press CLEAR from the
function selection mode. If the charger is left in
programming for an extended period of time, it
will automatically switch back to the display
mode.

Function Descriptions
The descriptions below are given in the following
order:
function number, factory setting (if one is
applicable), function name, and function definition.
1
DATE CODE
The EPROM date code is displayed as three
numbers (month, date, and year) with this function.
2
DAYS FROM LAST POWER FAULT
This function is a counter which adds one
every 24 hours and will reset to zero when the AC
power is interrupted.
3
POWER FAULT COUNTER
Counts the total number of power outages.
Whenever the charger is restarted and has run for 6
minutes, the power fault counter will increase by
one. To reset the counter, either use Function 16 or
the RESET function from a terminal (see Item 12).

This will display the lowest temperature
recorded inside the charger since the last RESET
was executed or since power-up.

"1"
THE USER MUST SET THIS TO THE
NUMBER OF CELLS IN THE BATTERY FOR THE
CHARGER TO OPERATE PROPERLY.
battery cell range for models 12/201 and 12/501 is
from 1 to 12 (for lead-acid, use 1 to 8). For model
24/301, the battery cell range is from 1 to 24 (for
lead-acid, use 7 to 15, and for nickel cadmium, use
10 to 24). BATTERY CELL SETTINGS FROM 1
TO 6 ARE NOT RECOMMENDED FOR NORMAL
USE ON MODEL 24/301. If the number of cells is
set at or near the upper limit and the temperature is
very low, the temperature compensation may cause
the voltage to go over its limit causing an error
(Function 10).
9
"1.00" FLOAT VOLTAGE PER CELL
The user must set this to the float voltage
per cell for a battery temperature of 77°F (25°C).
The range is from 1.00 to 3.00 volts.
electrolytic batteries, use a typical float voltage of
"2.23". THIS FUNCTION MUST BE SET FOR THE
CHARGER TO OPERATE PROPERLY.
10
"3.0"
This function adjusts the output voltage of
the charger depending on the temperature.
reference temperature for compensation is 77°F
(25°C).
If an external temperature probe is not
used, the compensation will be based on the
charger's
internal
compensation value is NEGATIVE because of the
inverse relationship between the temperature and
the voltage (as the temperature increases the
voltage should decrease). The range is from "-9.9"

compensation value to the battery manufacturer's
specifications.
Centigrade (°C) (see Function 15), change the
temperature compensation by the conversion factor
1.80 (Example: "-3.0" in degrees Fahrenheit equals
"-5.4" in degrees Centigrade).
11
"1.0"
Set this function to the maximum current the
charger should provide to the batteries (the range is
from 1 to 20 amps for model 12/201, 1 to 50 amps
for model 12/501, and 1 to 30 amps for model
24/301).
THIS FUNCTION MUST BE SET FOR
THE CHARGER TO OPERATE PROPERLY.
