Warning (cont.)
Description and Resolution This warning can be caused by the same conditions listed for Ambient Overheat. Another pos- sible cause would be a problem with the battery module, which could prevent the unit from provid- ing backup power. This warning will occur if the input voltage drops below the minimum allowable voltage. If the unit was online when the warning occurred it will transfer to battery backup. If the unit was in bypass the output will be turned off. The unit will reinitialize the startup sequence if input power returns to within specied limits. This warning will occur if the input volt- age exceeds the maximum allowable voltage. If the unit was online when the warning occurred it will transfer to battery backup. If the unit was in bypass the output will be turned off. The unit will return to normal operation if input power returns to within speci- ed limits.
Alarm State Alarm will sound for 1-second at 15- second intervals. Alarm will sound for 1/2-second at 10-second intervals. Alarm will sound for two 1/2-sec- ond beeps at 10-second intervals.
