12 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:
0 NO ERRORS FOUND
1
IMPROPER
OUTPUT
2
STUCK
BUTTON
3
INTERNAL
4 DEFECTIVE EXTERNAL TEMPERATURE PROBE
5 DEFECTIVE INTERNAL TEMPERATURE PROBE
6 VOLTAGE SET OVER LIMIT
7

8 BATTERY OVER TEMPERATURE
9 CHARGER OVER TEMPERATURE
10 EXCESSIVE CABLE DROP
11 BATTERY SENSE CABLE (IF USED)
12 PROGRAMMING
LOST
13 "1" 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.
14
"1"
DISPLAY TIME OUT
Setting this option "ON" (1) turns the display
off except for the decimal point in the lower right
corner after one hour of inactivity. Pressing any
display button will turn the display back on. Set this
option "OFF" (0) to keep the display active at all
times.
15 "0" TEMPERATURE
SCALE
Set this function to ON (1) if you want the
temperature display and 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.
16
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.
17
CLEAR ALL ERRORS
This function will clear all of the error
indicators. This is the same as the CLEAR function
from a terminal.
18
"0"
STOP SWITCH DISABLE
When set ON (1), pressing the STOP switch
WILL NOT shut off the charger's output.
19 "0" PRINT
INTERVAL
Setting this flag ON (1) changes the print
interval to 15 minutes. Setting this flag to OFF (0)
changes the print interval to one hour.
20 "0" LOG
INTERVAL
Setting this flag ON (1) enters data into the
data log every 15 minutes. Setting this flag OFF (0)
changes the log interval to one hour.
21
DATA LOG DUMP
Selecting this function will dump the
contents of the data log file to a printer
(approximately 380 lines). The data log dump may
be terminated by pressing and holding the CLEAR
button until "8888" appears on the display or by
striking any key on an attached terminal.
22 "0" BAUD
RATE
When this function is ON (1), the
communication baud rate is set to 1200. When the
function is OFF (0), the baud rate is 300. This
function affects both the printer and terminal baud
rate.
23 "0" 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. Set this
function to "1" to disable sample hold. Optimum
operation occurs when the function is set to "2".
24 "0" SET
PASSWORD
The charger may be used with a modem
over the phone lines. To discourage unauthorized
access, a simple password can be used (automatic
entry into the terminal mode may be gained if the
password is "0"). The password can only be
changed with the charger's push buttons. The range
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).
