201
Channel
No chargers assigned to output
channel.
Every enabled output channel
must have at least one charger assigned
to it. When none is found, it is presumed
that a charger has failed, has lost SENSbus
data communication, or has an incorrect
channel setting.
- Check for a charger that has failed
(indicated by its LED status).
- Check for disconnected or damaged
SENSbus data cables.
- If the output channel is not to be used,
disable it by using the keypad
"Enable/Disable DC Output Ch" setting in the
"Other Settings" menu or the PC utility.
202
Channel
Too few chargers operating.
The
combined output rating of all chargers
operating on this channel is less than the
channel's rated output. This can occur
because a charger has failed, has an open
AC input or DC output connection, has
lost SENSbus data communication, is
configured for the wrong output channel,
etc.
Note: the channel output settings are
used to determine channel-level output
current limit settings for "N+1" and "N+2"
redundant configurations; non-redundant
systems use channel settings of 0 which
allow up to 100% output from every
available charger.
- Use the "Set DC Output" setting in the
"Other Settings" menu or the setup utility to
verify all chargers' output channel settings.
Each charger must be set for the output
channel corresponding to its electrical DC
output connection.
- Use the setup utility to verify the channel
DC output current and power ratings. For
"N+1" or "N+2" redundant operation use the
required output rating, i.e. the total for the
minimum number of chargers ("N") that will
provide the necessary output ratings. Non-
redundant systems use 0 settings (which
disables this error check).
- If necessary, install additional chargers to
meet the required output rating (plus the
additional chargers needed for "N+1" or
"N+2" redundant operation).
- Verify that each channel is assigned enough
chargers to meet the required DC output
rating (plus any extra chargers needed to
provide "N+1" or "N+2" redundant
operation).
- Check for disconnected or damaged
SENSbus data cables.
- Check for miswired, disconnected, or
damaged input and output connections.
203
Channel
Charger assigned to a disabled
channel.
All chargers must either be set
for non-channelized operation (0, Default
output) or to a valid output channel that
is enabled in this unit or system.
- To use this channel, enable it using the
keypad "Enable/Disable DC Output Ch"
selection in the "Other Settings" menu or the
setup utility. Verify that the DC outputs of all
chargers assigned to this channel are
electrically connected to that output bus.
- To select a different output channel,
reassign the charger to match its actual
output channel connection using the "Set DC
Output" setting in the "Other Settings" menu
or by using the setup utility.
- To operate without channelized outputs,
use the keypad "Enable/Disable DC Output
Ch" selection in the "Other Settings" menu or
the setup utility to disable all output
channels for the display board. Then use the
