Temperature
The air temperature in the
battery string environment
is above or below
configured thresholds.
Default:
50.0° F (10° C): low
threshold
95.0° F (35° C): high
threshold.
Problem:
• Uncorrected high temperature can cause
permanent damage to the batteries.
• Uncorrected low temperature can cause a
reduction in battery runtime.
Response:
Check temperature control and
ventilation systems in the room, and check
for overheated batteries (usually caused by
overcharging).
Input Contacts Activation of input
contacts triggers an
alarm.
Check the status of the external monitoring
device that sent the input signal.
