Alert Screens and Diagnostics P12 7 5 2 1 A N D 7 5 2 2 B A T T E R Y C HA R GER S If at any time during the chargers life the red Alert light goes on, then the charger is not providing optimal performance. The below Alerts encompass all of the possibilities for the charger to under perform. Alerts will be indicated by the red Alert light as well as a pop-up screen explaining the reason.
Alert Screens and Diagnostics (continued) P12 7 5 2 1 A N D 7 5 2 2 B A T T E RY C HA R GER S AC Input Voltage Too Low The minimum input voltage for the P12 Battery Charger is 90V AC. However, due to common voltage sags caused by spikes in power, the internal hardware of the P12 Battery Charger can continue to charge for brief periods below 90V AC. If the AC input voltage drops below 75V AC, the alert screen on the right will appear. While in this state the charger will cease to charge any batteries.
P12 Optional Installation 7 5 2 1 A N D 7 5 2 2 B A T T E R Y C HA R GER S Integrate the P12 Battery Charger with Blue Sea Systems Automatic Charging Relays to take advantage of Charge Coordination. NOTE: If you have a Blue Sea Systems ACR with Start Isolation, it is possible to take advantage of your P12 charger’s ability to integrate in order to optimize charging of your batteries.
