Some errors the charger detects are more serious
than others. When a fatal error occurs, the charger
will shut off to avoid possible further damage to the
charger or batteries. The error code descriptions are
given below in the following order: error code
number, fatal error status (NF = non-fatal; F = fatal),
error code name, and error code definition.
1 (F)
Improper Output
- The charger is
unable to reach either the set output current or the
set output voltage. It will also occur if the input line
voltage drops too low to maintain proper output
levels. Verify the charger's output setting, line
voltages, and battery voltages before clearing this
error.
2 (NF)
Stuck Button
- A button on the front of
the charger is not working properly. If the button
cannot be made to work, the charger needs
servicing.
3 (F)
Internal
- This occurs if the control
module has an internal problem. The charger needs
servicing.
4 (NF)
Defective External Temperature
Probe
- This option is not available.
5 (NF)
Defective Internal Temperature
Probe
- The temperature probe internal to the
charger is not operating properly. The charger will
need to be serviced.
6 (F)
Voltage Set Over Limit
- The voltage
plateau has been set over the maximum level that
the charger is capable of producing.
7 (NF)
Charger Is Warm
- This error occurs
when the charger's internal temperature reaches
160
°
F (71
°
C) to prevent damage to the charger.
8 (NF)
Battery Over Temperature
– This
option is not available.
9 (NF)
Charger Over Temperature
– This
error occurs when the charger's temperature
reaches 170
°
F (77
°
C). At 160
°
F (71
°
C), the output
of the charger is reduced to protect the charger from
damage (error code 7), but when 170
°
F (77
°
C) is
reached the charger will stop until the temperature
decreases.
10 (NF)
Excessive Cable Drop
– The battery
voltage measured at the charger's terminals has
exceeded the voltage measured at the batteries by 4
volts. This indicates there may be a problem with
the cables between the charger and the batteries or
between the batteries.
11 (NF)
Battery Sense Cable
- This option is
not available.
12 (F)
Programming Lost
- If this occurs the
charger sensed one of the function variables to be
invalid and the charger will shut down. All of the
functions will have to be reprogrammed, and then
restart the charger.
13 (F)
Calibration Lost
- This occurs when the
charger senses a problem with the electronic control
module. If this occurs the charger will need to be
repaired.
14 (NF)
Battery Is Warm
- This option is not
available.
15 (NF)
Battery Is Very Cold
- This option is not
available.
16 (NF)
Voltage Outside Limits
- If the battery
voltage is sensed to be either higher than 3.00 VDC
or lower than 1.00 VDC, this error will occur.
9. MAINTENANCE
The battery charger requires minimal maintenance.
It should be kept clean and all connections tightly
secured. In the event of an intermittent operation,
examine and tighten, if necessary, all connections.
BE SURE THE CHASSIS IS SECURELY
GROUNDED. If any problem cannot be resolved,
contact NATIONAL RAILWAY SUPPLY.
10. SERVICING
If the battery charger operates improperly, check for
a possible error code number. When a problem
occurs that is not recognized by the charger, use the
following steps:
a. Begin by pressing all four buttons on the
front of the charger simultaneously. This
resets the charger and may correct the
problem.
b. Check the fuse(s) to see if it has blown and
replace if necessary.
c. Also check for proper AC voltage jumper
selection.
d. Check the polarity between the DC output
and the battery and make sure their
connections are good.
e. If the steps above do not solve the problem,
contact NATIONAL RAILWAY SUPPLY.
