Batt Ovtemp Limit
One or more of the Battery Temperature Sensors
is reporting a temperature above the limit
setpoint.
There are two user-adjustable Battery
Temperature Setpoints: Battery Over
Temperature Warning and Battery
Overtemperature Limit. The temperature in one or
more battery compartments has risen above the
limit setpoint.
Depending on user settings, the controls may trip
the battery breaker associated with the over
temperature condition.
Press “SILENCE” to silence the audible alarm.
Observe the One-Line Display. To identify which
battery cabinet is reporting the temperature
condition, press the “Battery Box” on the One-Line
Display to cycle through each battery compartment
or string. The temperature display is located under
the voltage reading in the Battery Box.
If the Common Battery Disconnect and/or the
individual battery cabinet or string reporting the over
temperature condition is tripped, check the following
settings.
Press “User Settings,” “Battery Management,”
“Battery Temperature” to check the current Battery
Temperature Setpoints. If none of the Battery Boxes
on the One-Line Display exhibit a temperature in
excess of the temperature setpoint in the user
settings, contact your factory-authorized service
provider.
If the overtemperature limit is being reported
correctly, investigate potential causes such as faulty
air conditioning, or air flow blockage and resolve.
Otherwise, contact your factory-authorized service
provider.
