Section 2: Controls and Indicators

Fault LED This LED flashes on-and-off during an error condition from which the unit will automatically recover and restart when the condition is remedied. The FAULT LED will be lighted steadily when any error occurs from which the inverter/charger cannot automatically recover. It is usually necessary to disconnect the AC or DC supply to recover from this type of error. An error condition is accompanied by an audible alarm if the alarm is enabled.

Temp LED This LED flashes on-and-off to indicate that the internal temperature of the Prosine inverter/charger is too high and the unit has shutdown. When the internal temperature of the unit cools sufficiently, the inverter/charger will automatically restart. The audible alarm that accompanies this condition (if enabled) will also be silenced upon auto-restart.

Reset Button The RESET button on the Faults panel has two functions: pressed and released, it will silence the audible alarm which, if enabled, will sound an insistent intermittent tone anytime an error condition occurs, which can be looked up in a table to determine the nature of the error. Press and hold the RESET button to display error codes. Error codes are listed in an Appendix to this manual.

Inverter Status Indicators and On/Off Button

Invert LED When the green LED labeled INVERT is flashing,

shorepower is not present, Load Sense is enabled, and no AC loads exceed the Load Sense threshold. The inverter is not producing AC power from the batteries. When the INVERT LED is lighted steadily, shorepower is not present and the

inverter is producing AC power from the batteries. The INVERT LED is not lighted when shorepower is present.

Standby LED When the amber LED labeled STANDBY is lighted steadily, shorepower is present and the inverter will pass AC power through to any AC loads that may be present.

If shorepower should fail or be removed while the inverter is in Standby mode, the inverter will automatically begin to produce AC power from the batteries, and the INVERT LED will be lighted.

On/Off Button. A button labeled ON/OFF is provided adjacent to the INVERT and STANDBY LEDs. When pressed, this button switches the inverter from On to Standby mode. Use in conjunction with the charger’s ON/OFF button to set the startup inverter/charger mode. See “Section 3: Configuration‚” on page 25 for instructions on how to set the startup inverter/charger mode.
