Error
Scope
Description
Corrective Action
Duplication is allowed for modules in different
units,
i.e.
with different "Unit Serial Numbers".
Modules using the “default” output do not use
charger positions.
the replacement charger for the same position as the
module being removed.
- To prevent confusion, the position jumper settings
should agree with the position markings on labels,
internal wiring,
etc
. (so the displayed module ID
number will match its physical and electrical position).
201
Charger
(or system)
No charger modules assigned
to output. Every
enabled charger output must have at least one
module assigned to it. When none is found, it is
presumed that a module has failed, has lost
SENSbus data communication, or has an incorrect
output setting.
- Check for a module that has failed (indicated by its
LED status).
- Check for disconnected or damaged SENSbus data
cables.
- If the output is not to be used, disable it by using the
keypad "DC Output #" setting in the "Other Settings"
menu or the setup utility.
202
Charger
(or system)
Too few charger modules operating
. The combined
output rating of all modules operating on this
charger output is less than the rated output. This
can occur because a module has failed, has an open
AC input or DC output connection, has lost SENSbus
data communication, or is configured for the wrong
output.
- Use the "Set DC Output" setting in the "Other
Settings" menu or the setup utility to verify all chargers
output settings. Each module must be set for the
output corresponding to its electrical DC output
connection.
- If necessary, install additional modules to meet the
required output rating (plus the additional modules
needed for "N+1" or "N+2" redundant operation).
- Verify that each output is assigned enough modules to
meet the required DC output rating (plus any extra
modules needed to provide "N+1" or "N+2" redundant
operation).
- Check for a module that has failed (indicated by its
LED status).
- Check for disconnected or damaged SENSbus data
cables.
- Check for miswired, disconnected, or damaged input
and output connections.
203
Charger
(or system)
Charger Module assigned to a disabled output
. All
modules must either be set for single output
operation (0, Default output) or to a valid output
that is enabled in this unit or system.
- To use this output, enable it using the keypad " DC
Output #" selection in the "Other Settings" menu or the
setup utility. Verify that the DC outputs of all modules
assigned to each output are electrically connected to
that output.
- To select a different output, reassign the module to
match its actual output connection using the "Set DC
Output" setting in the "Other Settings" menu or by
using the setup utility.
- To operate without multiple outputs, use the keypad
"DC Output #" selection in the "Other Settings" menu
or the setup utility to disable all outputs. Then use the
"Set DC Output" setting in the "Other Settings" menu
or the setup utility to assign all chargers to the
“Default” DC output .
301
Charger
(or system)
Missing charger modules
. A module that should be
present is missing, has failed, or is otherwise not
found on the SENSbus network.
The number of modules in this system must not be
less than the "Minimum System Number of
Chargers" setting. This setting defines how many
modules should be installed, particularly in "N+1"
and "N+2" redundant configurations (where full
output is possible without all modules operating).
This setting normally is 0 (Off) for non-redundant
systems, which disables this error check.
- Check for a module that has failed (indicated by its
LED status).
- Check for disconnected or damaged SENSbus data
cables.
- Use the "Minimum System Number of Chargers"
selection in the "Other Settings" menu or the setup
utility to verify the system charger count setting. For
"N+1" or "N+2" redundant operation this should be the
number of charger modules connected to the SENSbus
network. Non-redundant systems normally use a 0
setting (which disables this error check), but may be set
if error checking is desired.
