Troubleshooting
Table 4-1 lists possible problems that might arise when using the charge
controller.
Table 4-1 Charge controller problems
Problem Possible Cause Solution
Battery voltage is
exceeding bulk and
float settings in cold
weather and not
reaching settings in
hot weather.
The BTS is compensating charging
voltages based on battery
temperature.
No problem. This is the intended
operation.
The charge
controller’s Error/
Warning (red) LED is
on or flashing.
An active fault, error, or warning is
present on the charge controller.
See “Viewing Active Faults, Errors,
and Warnings” on page 3–5 to
determine which alarm is active on the
charge controller. The tables in this
section provide detailed information
on why various alarms could be
occurring on the charge controller.
Battery equalization
was enabled but did
not occur.
The charge controller must complete a
bulk/absorption cycle before it can
initiate an equalization cycle.
See “Equalizing Batteries” on
page 3–13 for information on
equalization charging. See “Viewing
Status Information on the Charge
Controller” on page 3–2 for information
on determining the status of the
equalization cycle.
BTS information does
not show up on the
charge controller’s
Meters screen on the
SCP.
The BTS reading is only shown on the
Meters screen if the BTS is physically
connected to the device you are
viewing on the SCP. All devices share
BTS information, but they only report
the information to the SCP if they have
the BTS plugged into their BTS port.
Navigate to the Meters screen on the
SCP for the device that has the BTS
connected to it.
