All of the situations listed above indicate normal system operation; no action is required. However, if the BBU pump is running or
has run, check the primary pump and actively monitor the charger status for battery life. Always reset the charger after the pump
runs.
During normal system operation, the SYSTEM ALERT LED blinks while the float switch is on,indicating the pump should start
within 3 seconds. The "AC POWER" LED is lighted (solid or blinking) as long as the system is plugged in to an operating AC power
circuit.
