NOTE: Crown and Trojan AGM batteries should be charged with the GEL setting.
**The charger has been tested on batteries from the following manufacturers:
Trojan flooded cell
US Battery flooded cell
Deka flooded cell
Notes on LED indications per DoE compliance:
When first connected to DC (AC not connected), the LEDs will display one or more of the following:
The LEDs will flash the charger's ID code (this is for PCS internal use only). Once the LEDs flash the ID, they will
only display one yellow LED. This configuration will remain until AC is detected and a charge cycle is in progress.
There is also a possibility the LEDs will not flash their ID code and only show a yellow LED.
Lastly, the LEDs may not flash their ID code and may not show any LEDs until AC is detected.
If the AC line and neutral wires are reversed, the unit will wait 2 minutes before starting a charge. NOTE: The 2-
minute wait period will also be a factor if the charger is being powered by anything other than normal grid AC such
as a conventional generator, inverter, etc.
If the AC plug is disconnected during charge, the unit will turn off as expected. The user may hear some clicking
noise, but should not be alarmed. This is the Powered by Battery/DOE functionality checking for AC connection.
