ERROR CODES
This function gives numbers that represent
problems that have occurred with the charger. If a
printer is connected to the charger, error messages
will be printed. For a detailed explanation of the
error messages, refer to Item 10. The error codes
are:

EXTERNAL TEMPERATURE
PROBE
If an external battery temperature probe is to
be used for voltage compensation, set this option
ON (1) (see Item 7). Set this option to OFF (0) if the
voltage compensation is to be based on the
charger's internal temperature sensor. If this option
is selected without an external probe connected, the
charger will respond with an error code.

DISPLAY TIME OUT
Setting this option "ON" (1) turns the display

option "OFF" (0) to keep the display active at all
times.

TEMPERATURE SCALE
Set this function to ON (1) if you want the
temperature

compensation to be in degrees Centigrade (°C).
When this function is OFF (0), the temperature is in
degrees Fahrenheit (°F). IF THIS OPTION IS SET
TO 1, THE TEMPERATURE COMPENSATION
(Function 10) HAS TO BE ADJUSTED OR
BATTERY LIFE WILL SUFFER BECAUSE OF
OVER- AND UNDER-CHARGING.

RESET STATISTICAL DATA
This function resets all of the minimum and
maximum temperature data and sets the power fault
counter to zero. This is the same as the RESET
function from a terminal.

LOG INTERVAL
Setting this flag ON (1) enters data into the

SAMPLE HOLD
When this function is set to 2 (on models
12/501 and 24/301 only), the battery voltage is
measured through the battery sense cable. If the
battery sense is not connected, error number 11 will
occur. When this function is set to 0, the output
voltage of the charger is sensed through the DC
cables.
The output is then compensated for the
voltage drops which occur in the cables and the
terminals.
If the cable drop becomes excessive,
sample hold will be disabled until the problem is
corrected and the errors are cleared.

entry into the terminal mode may be gained if the
password is "0").

of the password is from 0 to 255. When the charger
requests the password, enter a number in the range
from –9000 to –9255, where the last three digits are
the ones selected from the front panel of the charger
(see Item 12).
